Recently there is news that the Seoul City will implement as 2014, 30% (35 thousand)of the city’s civilian facilities ( 114,000 )will be built for Eco friendly LED shops. The main target is sauna, gym and restaurants which open for 24 hours and consume a large quantity of energy.

To this end, Seoul and (social) Korea catering Central Council, (Agency) South Korea bath central Committee industry will sign the business agreements on completion of 35 thousand green LED store as for the 2014 to ensure that the power of promotion on July 29.

Seoul plans to actively announce that lighting electricity consumption savings is nearly 30% after the CFL and other ordinary lamps are all replaced with the LED, and provides a variety of incentives to attract private commercial outlets actively spontaneously replace. The existing lighting is the three wavelengths (25 watts) in most of the shops, after replaced with the bulb-type LED (7 ~ 10 watts), they can re-use the existing fixtures, which is easy to replace, the cost is also low.

First, the Seoul will provide the shops that plan to replace the more than 90% of the existing lighting with LED lighting maximum one billion won low-interest loans (2%) to reduce the cost of replacing the initial burden of LED lighting.

In addition, the Seoul City has associated with the “bulb-type LED lighting direct selling marketing” the Seoul City and the green consumers co-promote to provide with the LED lighting whose average price is up to 35% cheaper than the market price.

In this way, when the existing lighting is replace with the LED light, the payback period will about less than a year, the time is short, but also sustainable enjoy preferential tariff reduction, Seoul City plans to cooperate with the two central committee actively promote replacement works.

The stores completing the replacement will be granted “green LED shop” certification mark, which will be affixed on the door; also set up, “we plot the energy shop” (tentative) column on the district newsletter to publicity the store.

Seoul and the (social) Korean restaurant industry central committee are making efforts to conserve energy by the business agreements, it is also committed to mutual effort to achieve the food waste billing system by weight and radically reduce food waste.

We just generally y care about the optical parameters of the domestic LED lamps that is currently produced at the design stage, we are always considering choosing which chip and driver, how to cool and so on. However, there is no effective means of control in the production process, including large companies , too. How to control the full range of optical parameters in production process?

The incoming inspection firstly detect whether the parameters of each volume chip are the same as per roll labels of , in general, brand chip is unlikely mistaking the entire volume , so detecting one or two pcs is OK, the parameters mainly include the luminous flux , color temperature , power, current and voltage. The sampling ratio should be increased for the unknown branded

In the production process, it is essential that the kitting is checked and recorded . the color temperature, and even different partitions should be completely recorded in the record of the feeding. This process is often ignored because everyone thinks is a simple action . To prevent errors , in addition the detailed records need to be checked and then assemble on the SMT lines . Of course, there is also possibility that the color temperature is made mistake due to the negligence , it is best to use the bar code to control , designed frame special , different barcodes can not be put on , thus avoiding the possibility of manual errors .

The next the quality of patch also affect the normal use of the chip , such as Weld, the solder temperature is so high that burn the chips, the electrostatic breakdown the chips. So the paste deadline should be regularly checked , prohibit using the expired solder paste . Regular cleaning and inspection the tension of the steel is to ensure the thickness and integrity of the solder paste. Testing the thrust and the thickness of the solder paste can guarantee the quality of following weld after the solder paste is printed on the PCB,there is only a handful factory that is really do. It is best to use the PCB board with the temperature sensors to control the temperature curve , so that no accident would not have occurred that the high temperature burn chips. For electrostatic protection,the static ring should be started checking before the workers enter the door , all of the workers have to wear the wrist strap and dress in the static clothing . the whole floor should be painted the antistatic protective layer, all table and transfer device must be antistatic materials. The Corrugated boxes is not anti-static , which is a little known , many workers who are pursuit of the convenience directly use the corrugated board to separate PCB, which is very dangerous. the whole plant must be the purification plant isolated with temperature and humidity control .

After the SMD LED chips is attached,it should be lit to test , the general plant seek the efficient, just using the small current to light up to filter whether the LED is affixed. We all hope the problem of the fixture can be found after the aging test . In fact, this is a common problem of LED lighting plant , preferably test the associated optical parameters after the LED board is affixed, in order to avoid post- production rework. Currently on -line detection is still relatively weak , few can do online testing. Many people think that it is not necessary, as long as the LED chip is selected that all parameters can be granted, which is obviously quite different with the reality. If you can not do online , at least a few in every batch shall be selected to test with the integral ball .

To the lamp assembly, what shall be done for incoming inspection should be the same as that of the LED board,select the sampling to send to the integrating sphere to measure all the parameters. In the assembly process, the IPQC should drawn once every two hours,the final testing before storage is essential.

Some detection may be detected when aging. Currently we are observing and inspecting the brightness and color temperature , but which is affected by the human factors .It is best to measure the parameter while aging, which requires a device to guarantee. I believe that such devices will be available in the near future as LED products more and more mature!

Whenever the Christmas and New Year these grand festive come, the various buildings and trees and flowers are beautiful s with gorgeous dress against the backdrop of the LED strip lights, apparently, LED strip lights have been used as excellent decorative lamps into our lives, but, for most of us, it is not clear how to install LED strip lights, here I will guide you how to install the LED strip lights.

Scope

LED strip, LED light bar has been widely used in furniture, automotive, advertising, lighting, ships and other industries.

Installation Method

` the bandwidth of four wire LED strip lights is about 22mm, the thickness is about 8mm, the weight is about 0.25kg / m (4 meter by Kg)

athere are a total of four wire conductors for the LED strip lights, three rows of lights (note not the four rows of lights), there is 1 meter and 24 lights in each row, 24 * 3 = 72. Because the power of each lamp beads is 0.05W, the power of the 72 beads LED strip light is: 72 * 0.05 = 3.6W.

bthere is the “scissors” mark per meter , only to have to cut on the tag, the scissors cut or the wrong side will lead to that one meter does not shine! Some miss a few because of hitting the mark, it is best to look the mark position carefully before you cut, according to the middle of no where connections to be cut, which can be carefully seen.

c Each strip light must be fitted with a special plug (a plug with a transformer); connection sure to remove the clear plastic cover, and don’t cover until the light is connected and tested. Must not be directly connected with the cover, the short circuit is easy to occur!

When the strip lights is installed, it is generally put on the light trough, and put straightly is OK, you can also use string or thin wire to fix. For the exterior or vertical loading, a clip and a tail plug need to be purchased . The genuine clip is fully transparent, preferably mark with the waterproof glass glue after the installation in the tail plug and the plug, so better waterproof.

Because LED strip lights is known as energy saving, colourful light, convenient layout, etc.,which are widely used as decorative lighting, when using the LED strip light in daily life, we are always troubled in that the LED strip lights can’t be lightened up, then what causes it is not lit? Only identify the causes to solve the problem, the following points summed is clear to everyone :

1, the packaging protection of the LED light strip is imperfect, resulting in the lamp beads is damaged by the impact during the transport process

2, there are cold solder joints on the weld of the LED light bar , the vibrations causes that the solders fall off and result in the lights is not bright during transport

3, less solder, solder joints easy to fall off

4, the solder is of poor quality, the joints of LED strip lights prone to embrittlement shedding in the process of being bended.

5, the bending angle is too large when installed, resulting in that the joints of the LED light strip separate from the copper so that lead to not bright.

6, excessively extrude the products when installing, leading LED strip chip is damaged or joints deform and fall of without light

7, the solder resist layer of the circuit board of the LED light bar is too thick, when welded, the soldering and circuit board can not be completely fused together, but also a Weld phenomenon

8, LED light bar can not be distorted during installation, if distorted, which will cause that the joints of the LED light strip fall of and lead to not light

9, electrostatic burned, because the LED is an electrostatic-sensitive components, there is no good static protection, which will cause that the chip is burned..

As the fourth -generation light source , LED lighting is known as the high luminous efficiency , energy saving , long life, maintenance-free , highly safety and reliability , and environmental protection and so on . With the rise of LED lighting products and the popularity ,its product quality is paid more and more attention by the public.

The pass rate of security is 80-90%

According to the preliminary statistics , the safety pass rate of the product checked from the manufacturers is about 80% ; the one-time pass rate of safety and performance of the product the enterprises entrust check is 70%.

According to the briefing , because LED lighting products too rapidly develops , the quality status and trends is not optimistic. the LED light that is used for Indoor Lighting is the Downlight, LED tube light, LED light bar , LED ceiling light and other forms ,according to the analysis of the testing situation of the LED lighting product, the failed projects mainly focus on thefour aspects: First, unequal power , the labeled power of the LED lights is incompatible with the standard limits power , which generally tend to be large , easy consumption ; Second:the luminous flux reach the value the manufacturer claim,which is generally low ; third is that the rate of the maintain is not enough, because of chip quality and other issues, the rate of the maintain light is not high, which is easy to darken ; Fourth us structure , the protection against electric shock and fire and heat-resistant of insulating material is failed to make the original protection against electric shock of the lamp is failure, resulting in that the live parts is exposed or the short circuit and other safety hazards .

China is still reference to the testing standards of the U.S. “Energy Star ” to test the safety performance and life of the LED lighting product , other supporting standards and supervision and management measures have not yet be perfected, the national testing agencies are being made preliminary data collection, actively participate in the establishment of national standards of the ” reliability test methods of the Semiconductor LED lighting ” .

Which LED lights is suitable for indoor lighting ?

The Prettier and brighter,not the better , we should be more concerned about security. Should choose the lamps which is of high protection level , structural, and low color temperature . A lamp includes two parts that is the lamps and lighting, of which the fixture ensure the safety of use , such as the starting power of the LED lamp is very important to ensure the integrity of its sporadic ; the sources have good light color , and its luminous flux and color temperature should meet the standard requirements , such as the lamp used for writing should have a low color temperature light , high color rendering index , but also restore the original shades ; pay attention to the stroboscopic of the high frequent lights , because the security is controlled by the national compulsory standards , and the power , lumen light and other optical characteristics are determined by the manufacturer ; what should be considered is more blue light hazard the LED light emit.

How to detect ?

The safety, light, life is called ” three threshold .” of the LED lighting products

There are are three basic indicators testing the safety of the LED lighting product: First, dielectric strength, namely anti- pressure capability ; Second, the insulation resistance and leakage current ; Third,the grounding resistance .

The light detection is firstly accomplished by the integrating sphere to measure the performance and characteristics of the light and color , the large distributed photometer lamp is used to measure the light distribution to identify whether there is the light pollution on the surrounding environment . Followed by 3000 hours or 6000 hours ignition cycles testing the light color ,those meeting the requirements is qualify.

Inspection approach

Having bought the LED lighting products, we want to check it is eligibility or not , the semiconductor lighting products can be sent to the National Quality Inspection Center to commission the inspection , the inspection cycle of the routine project is 10 days, the number of samples tested depend on the test need, the inspection charging is determined by the fees of the state regulation standards .

Nowadays,the LED flood light such as the portable 10W LED flood light and LED tube light are the most widely used as the representatives of the decorative lighting and the home lighting in daily life,the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness is needed to illuminate,meanwhile,there a large number of factory engaging in developing and producing the LED light,Lead Lighting is just one of them,which adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED floodlight so that fully guaranteed stable and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is Known as energy-saving and environmental protection ,login http://www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

LED lighting is lighting that the light-emitting diode is used as the light source ,which is known as the third light revolution and has the characteristics of energy saving, environmental protection , long life , rich colors, shock-resistant. Its applications is very broad , the earliest use is the indicator and signals , currently widely used in landscape lighting, automotive lighting , backlight, general lighting and other fields. The general lighting can be divided into indoor lighting ( the typical lighting is LED tube light and LED bulb used in office, home , shopping malls, hotels, etc. ) and outdoor lighting ( the power LED lighting that is the LED flood light such as the rechargeable LED flood light 20W and LED road light used on the roads, squares , tunnels, etc. ) . Theoretically , LED lighting efficiency is 120 lm / W, which can be up to 250 lm / W in the future and is much higher than the previous two generations of light ; the life of lamp source is 50,000 hours , the life of the lamp is up to 25,000 -3 million hours, which is quivalent to 25 times of the first generation light source ( such as incandescent ) , about 5 times as much as the second-generation light source ( such as fluorescent lamps , home energy saving lamps, high pressure sodium ) . In the general lighting field, what type of LED light technology is more mature ? Geng Bo who is the Deputy Secretary of State Lighting R & D and Industry Alliance told the reporters , LED lighting is developed from the small power , compared with the LED road lights,LED floodlight ( 100 watts ) , etc. power lighting , the technology of the household, commercial indoor LED lights ( 30 watts ) is relatively more mature and suitable for promotion. But the qualified interior LED lighting products is at least 40 yuan / lamp , which is much higher than fluorescent lamps . The states should increase subsidies to promote the spread.

The Inspector Li Yiwu working in Nanjing Urban Management Bureau , told reporters in Nanjing , about 85 percent of the landscape lighting is LED lights. “LED can achieve color lights, coupled that the landscape lighting is generally low-power light ,the technology has matured, which enjoy a great popularity , while the street lighting is generally high power lamp , it is more difficult to integrate the technology.”

Nanjing lighting Institute vice president Yang Haifeng calculated : by comparison with a 35 -watt ordinary spotlights, 4.2 watt LED lamps can achieve the same lighting effects , assuming work for five hours a day,56.2 degrees electricity is saved save to a kilowatt a year , take the 0.8 yuan one degree electricity cost for example,we can save 44.96 yuan each day.

Nguyen who is the Deputy Secretary of the National Semiconductor Lighting R & D and Industry Alliance said that many countries are promoting LED lighting, such as South Korea proposed that the country achieved 30% of the LED light fixtures by the end of 2012 ; U.S. promote LED lighting by the subsidies of power companies in the individual states. But the developed countries different with the China vigorously promoting the LED lights,the consumption capacity is high , home lighting market is faster developing ; while the roads and other infrastructure construction has been completed , the quantity of the municipal procurement is less .

General Motors announced that the LED lighting would be used as all the external light source of its subsidiary Cadillac ELR, which also means that Cadillac EUR will be the world’s first electric cars whose all exterior lighting as which the LED will be used.

The obvious advantages of LED lighting is also starting to get a lot of use in automotive lighting. China’s automobile production and sales are very large, according to China Association of the statistics of the Automobile Manufacturers, China’s automobile sales were 19,271,800 and 19,306,400 last year, an increase is 4.6% and 4.3%, driving significantly flourish of related auto parts industry, of which the growth rate of the LED automotive lighting is nearly 10 times more than the sum of production and sales.

According to the Ministry of Planning, automotive lighting need to complete the reduction emission targets of the carbon dioxide by the end of 2015. The LED has the advantages of long life, brightness, low power consumption,for the automotive applications,it is better to reduce the energy consumption. In addition, LED lights can withstand higher intensity strobe,which plays an important role in the car lighting; the response time of the LED lights is shorter, so that can be effectively reduce the reaction time and the incidence of traffic accidents.

However, there are not many of the relevant enterprises in China, the technical strength is not strong enough, which gives an opportunity for other manufacturers. Since the LED lighting manufacturer in Taiwan and in Europe and America found this market,they have also begun to enter the mainland automotive LED lighting market.

Taiwan LED lighting companies whipped a boom of the transition to the automotive lighting last year. Including Epistar, Formosa Epitaxy, AU Optronics, and other established companies, including the East Bay, have extended their own business tentacles to the international automobile brands, and made advantage of the advantages of the mainland labor cost, and actively invest and build factories in mainland China, to speed up the pace of development of their cars in the field of the LED lighting.


Of course, in addition LED lighting is not only applied in the car, as the third generation of lighting that is based on the semiconductor light-emitting diodes, but also closely connected to the fashion design, agriculture, medicine, aerospace, etc. industries to give us the more perfect visual experience and convenient services.

Blue LED lights really is so much harm to our eyes ? Is the Called ” blue spill ” really “potential killers “that hurt our eyes? Many people have had a doubt and anxiety after hearing the problem that the blue LED lamps injury our health , the experts say that LED lights used in outdoor and large spaces is no problem, but the family should be used with caution , especially the three groups of people need to be extra careful.

Although on the issue that the blue LED injury our health , the industry and experts ‘ opinions are not entirely consistent. But one thing has not disputed that the LED light belongs to the rich blue. ,Mou Tongsheng who are the member of the International standardization of optical radiation safety committee, professor of the ZhejiangUniversity reminded, there are three types of people who should be used with caution , first class , apparently, is the delicate eyes of children . The second category , diabetes ,since developed for ten years ,there are lesions of the retina , the approximately of retinal withstanding the light damage is declined significantly. The third category is the patients taking photosensitive drugs, there are many light-sensitive drugs in our lives, such as doxycycline , ciprofloxacin, oral hypoglycemic agents D-860 etc, having taken the pills,the light damage may be more obvious , not only to be careful with the light , the sun should be extra careful .

The blue light does not mean blue light , but the high energy visible light that is of the wavelength of 400-500 nm . It can penetrate the lens to reach the retina , causing optical damage and accelerate the oxidation of macular cells . Thus , the blue light is the most hazardous visible the study confirmed.

How to reduce the harm caused by LED lamps ?

LED light is known as energy saving , but which must avoid a very high color temperature. ( Indoors, color temperature to come down. )

What is the color temperature ? The so-called color temperature is the scale measuring the light source and color , the low color temperature is the warm light we usually say , the red component is more, less blue component . Conversely, the color temperature of the cool bluish light is relatively high . Among Our common light sources , the candlelight is of about 2000K color temperature, incandescent lamp is 3000K, the morning sun is about 4400K, noon rose to 5600K. YuAnQi who are the president of the Senior Engineer , Shanghai Illuminating Engineering Society said that , what is the best is that conform to the laws of nature when we use the light in different times of a day, and the color temperature of the LED lights is currently generally high on the market , which can cause interference on the human body clock more or less :

when most of the Family use the lights is at night , which require the low color temperature light , use the white lighting products beyond the color temperature for long time will affect sleep, affecting the disorders of the biological clock , thereby reducing the human immune system .

The color temperature of most of lamps isn’t marked on the packaging on the market . There are two just marked on the manual . Experts call the State should provide that how much the color temperature of the lighting products should be clearly marked on the packaging.

Consumers should also avoid a misunderstanding, that is , the brighter the light, the better . LED lamps is best to be accompanied by the shade, on the one hand , the light can be softer,on the other hand , testing proved that this can reduce 1-2 orders of magnitude of the blue light spill . Many manufacturers in order to improve the light efficiency , the most obvious is the LED tube, many of which were a bare one , this is uncomfortable for people . there is a hood under the table lamp , which make that the dazzle light becomes not.

Previously want to talk underwater, we mostly use the ultrasound to send dialogue, but this method is very expensive. Divers are generally expressed in gestures, but which only can pass a simple meaning, moreover for the beginners, they may not remember clearly, they would be confused in the crisis and affect communication.

In order to solve the problem of underwater communication, with the help of the LED lights Okinawa, Japan, researchers have developed a set of system, which is used to transmit voice. The Principle is that the sound waves is converted into the LED lights, and then emit to the sensor received by the other and then the light is turn into the sound waves. If the light is blocked, leaving only noise.

The researchers said that the system can only communicate in one meter range at the early stage of development,. But then they took into account the volume, transmission speed, sound, and the diving depth and other factors, finally broaden the scope of application of the system.

Currently, even the distance between the two divers is 30 meters, this underwater communication tools still can be used, either at a depth of 30 meters underwater to communicate. Fully charged, then it can be used for four hours, the system can not only be used underwater, there is no problem that those who are on the shore talk with the divers underwater.

The researchers said that the current system is of large volume, they will be committed to developing a smaller mask to facilitate people to use in different industries.

There is no doubt that LED lighting technology as the third generation of the semiconductor applications also can be perfectly combined with the communication.Nowadays,the LED flood light and LED tube light is most widely used as the representatives of the decorative lighting and the home lighting in daily life,the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness is needed to illuminate,meanwhile,there a large number of factory engaging in developing and producing the LED light,Lead Lighting is just one of them,which adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light so that fully guaranteed stabe and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is Known as energy-saving and environmental protection ,login http://www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

LED lighting requirements for low-voltage driver chip

1.The input voltage range of the nominal DC of the driver chip should satisfy 8 ~ 40V, which is to cover a wider application needs. Pressure capacity is preferably greater than 45V. When the input is AC 12V or 24V, the output voltage of the simple bridge rectifier will fluctuate with the grid voltage, especially when the voltage is high, the output DC voltage will be high. If there is not wide input voltage range for the driver IC, which tends to be

breakdown when the grid voltage rises, thereby burning the LED light source.

2.the nominal output current of the driver chips required is greater than 1.2 ~ 1.5A. For the LED light source used for lighting, the nominal operating current of 1W LED light source is 350mA, 3W LED light source nominal operating current is 700mA. Power LED light source needs more current, the LED lighting driver IC selected must have enough current output, the driving IC must also be operated at the optimum working area that is 70 to 90% of the full load output when the product is designed. There is poor heat dissipation when the driver IC is used in the small spaces at the full-load output current, which easily lead to fatigue and early failure.

3.the output current of the driver chip must be kept constant, so to stabilize the LED light, no flash. When the Same batch driver chip is used under the same conditions, the output current should be as consistent as possible, which is discrete to be small, so that ensure the effectiveness and orderliness on the high-volume automated production line. For the drive chip whose output current has certain discrete, required the sub-file selection before the factory or production line, adjust the size of the resistor set by the current on the PCB, so that LED constant current driver of LED lamps board produced is consistent with the emission luminance of the similar light source in order to maintain the consistency of the final product.

4. the package of the driver chip should facilitate rapid cooling of the die of the driver chip, such as the die is directly bind on the copper, and there is a direct extension of the pin outside of the package, in order to that the copper foil directly soldered on the PCB rapidly transfer the heat. If the chip that is similar to the 4X4mm through 300 ~ 1,000 mA current for long time, the power consumption and heat is inevitably generated, therefore, the physical and thermal structure of the chip itself is also very important.

5. driver chip anti-EMI, noise and high pressure capability is also related to that whether the entire LED lighting products can pass CE, UL certification, so the advanced topology structure and high-pressure production process should be used when the driver chip is designed.

6.driver chip’s own power requirements is less than 0.5W, the switching frequency is greater than 120Hz, in order to avoid visible flicker produced by the frequency interference.

In short, LED driver chip urge the green lighting to the development of innovative design. LED lighting without driver chip, requiring multi-functional LED light source driver IC. If the power supply that is less than 36V AC is used for the LED lamps, the non-isolated power supply can be considered; if the choice is 220V and 100V AC power, you should consider the isolating power supply. For the AC 100 ~ 220V drive chip directly used, because the application excessively depends on the volume demanding, there is higher demand, the greater difficulty on the technically, the countries are currently making efforts to develop. The Massive demand for LED lighting market gives the chances of success to all the IC design company again, if rapid transformation and pushing the product as early as possible, then there is a lot chances to win.

As we all know, the 3528,3014 we often said refers to a package size of lamp beads, 35 refers to that the length of the long side of the lamp beads is 3.5mm and 28 refers to that the length of the short side is 2.8mm, and so on.

Types of lamp beads:

1.The first generation: straw hat lamp beads,which is the indicator we are used to see, the single brightness is low and the power is small,what the significant feature of the LED tube light produced is that the number of the lamp beads are over many,

2.The second generation: 3528 SMD As technology advances,the straw hat lamp beads is gradually replaced by 3528, power increases, single brightness can reach 7-8 lm,the lamp beads is also much more,resulting in the disadvantage that is the high failure rate.

3.Third Generation: 3014 SMD thanks to the emergence of the 3014,the price of the LED fluorescent decreases, the power of a single lamp beads is up to 0.1W, the single brightness is 12-13 lm that is nearly 50% higher than that of the original lamp beads.

4.Fourth Generation: 5630 SMD The advancement of the manufacturing technology born the 5630, single power is 0.5W and single brightness is 50-60lm, the emergence of 5630 rapidly industrialize the LED tube, the energy-saving effect is widely used in factories, hospitals and other long lighting.

5.Fifth Generation: 3020 SMD the emergence of the 5630 contribute to large-scale commercial use of the LED tube light, but the only flaw of the 5630 is so high brightness that single spacing is large, resulting in poor light efficiency, the emergence of 3020 make up for this flaw, single is 0.2W, brightness is 22-24 lm, making the brightness best combine with the light efficiency.

When the power outage at home, do you sill look for the flashlight with stumbling gait? Recently, LED bulbs that is priced at $ 15 (about 91 yuan) and built-in the lithium battery has solved the problem. The bulb named Ascella continues to lit by an internal battery when the power outage to attain the emergency lights effect. Interestingly, Ascella can also be removed from its socket, used as a flashlight.

There is a mode selector switch on the Ascella bulb. Only after switching to emergency mode, Ascella continue to shine during a power outage. The life of the Ascella built-in battery is up to 3 hours. However, when the battery power, the brightness of the Ascella lamp will decline. After Ascella Refit is installed on the base, the internal battery can be filled within three to four hours. In addition, the official said the life of Ascella bulb is up to 18 years under the using frequencies that three hours a day.
Ascella bulb actually not so easy to use. In the actual test, we found that, Ascella brightness is equivalent to that of the 30W ordinary light bulbs, although the official called brightness is up to 150 lumens. In addition, charging, even if the Ascella is mounted on the base, it can not properly lit. I do not know if that was a design flaw.

The idea of the Ascella bulb is still very new. However, the brightness and functional defects makes this bulb is greatly discount the value in actual use.

However, it is clear that LED lights are applied more widely opposed to the traditional fluorescent lamps and energy-saving , with the innovations of the LED lighting technology and people’s increasing emphasis on environmental protection,the energy saving and environmental effects of the LED light is more and more obvious, and the LED light that is based on the Semiconductor is perfectly combine with majority of industries such as the clothing design, medicine, agriculture, aviation and many other fields to provide us with the unique experience and convenience.Nowadays,the LED flood light and LED tube light is most widely used as the representatives of the decorative lighting and the home lighting in daily life,the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness is needed to illuminate,meanwhile,there a large number of factory engaging in developing and producing the LED light,Lead Lighting is just one of them,which adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light so that fully guaranteed stabe and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is Known as energy-saving and environmental protection ,login http://www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

Recently, the U.S. Department of Energy (DOE) published a report on the life of the solid-state lighting product and reliability analysis. What has been clearly pointed out that there is no perfect evaluation way in the current industry standard to define the system life of LED lamps In the report.

Up to now, we have waked on a long way about the development of LED components and systems testing and evaluation criteria of the LED industry. However, as the DOE reported, there is currently no way to provide a very feasible way to assess the expected life of the lamp in the industry. Although lumen maintenance testing and planning standards have been improved, but it is still difficult to quantify for the life of the drive and system-level color maintenance.

DOE’s new report aims to define the existing standards and planning standards, and analysts to point out the existing defects defining LED lighting performance. According to the report, the problem mainly exists in: the lumen attenuation is used as the sole elimination mechanism of the LED lamps in the existing methods, there is no standardized assessment methods to resolve the components in addition to the sources.

IES LM-80 standard has defined the testing methods of the white LED component. LM-80 has regulated the lumen attenuation standard in detail, also has defined the colors maintenance of the component and the color drift. IES TM-21 standards adds the approach planning the life beyond 6000 hours LM-80 test hours required.

In addition, IESLM-84 standard will define lamps or the lighting level lumen and color maintenance measurement method ,which also provides approach planning the life that is based on the data of LM-84 lamp. Thereafter, IES may also add lighting planning approach for the TM-28.

The report does not provide a comprehensive lifetime or reliability of measurement and planning solutions. Report said, as the LED and SSL technology matures, the problem will gradually disappear, but the product will continue to be subject to the impact of a variety of mechanisms and eventually will been eliminated.

DOE also said that as the product life expectancy decline from 30 years to 10-15 years, industry conditions will likely improve. This is because the trend improving lighting cycles is getting shorter. However, the life expectancy of the lighting shortened will produce more waste materials, affecting sustainability.

Topics has not covered in the report include that the mixed color LED used or the non-contact LED phosphor technology relying on the blue light LED affect the lighting life and the reliability. Existing industry standards such as LM-80 only defines the testing the methods of the fluorescence conversion type white LED. However, other system architectures is increasingly popular in some application.

At the same time,there are a large number of high-quality LED manufacturers pouring into the international markets,of which the lead lighting is just one,lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while the low voltage constant current driver convert the AC into DC so that improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ,login http://www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

The choices of factory lighting plague many people, then which kind of plant and height and area of the plant and lighting is the most reasonable in the end? The lighting expert will tell you: how to choose and design the preferable factory lighting?

1 choice for the lighting way

(1) For the illumination requirements that is higher and the working position which is not of high density, the mixed lighting should be adopted a place where it is unreasonable to separately adopt the general lighting

(2) less demanding on the illuminance, when subjected to the technical conditions of production constraints, which is not suitable for installation of local lighting, or unreasonable use of mixed lighting, general lighting should be used alone.

(3) the partitioned general lighting can be adopted in work area where the lighting illuminance needed is more than the general.

(4) When the district illumination can not meet requirements for general illumination ,the local lighting should be added.

(5) the partial lighting shouldn’t only be installed in the work area.

2. illumination standards

The illuminance values of the factory lighting design should be based on the national standard GB 50034 – 2004 “architectural lighting design standards” requirement to select. This standard specifies the illuminance values of the general lighting of 16 Congress of industrial building. More specific illumination standards of all kinds of factories workplace shall also be relevant industry regulations.

3. Lighting quality

Lighting quality is the flag that measure the quality of factory lighting design. It mainly includes the following:

(1) select the lamps whose efficiency is high and the light distribution curve fit. According to the rate of Index feet of the height of hanging lamps in the plant room shelf is to select the different light fixtures.

When RI = 0.5 ~ 0.8, should use narrow light fixtures;

When RI = 0.8 ~ 1.65, the appropriate selection is light fixtures;

When RI = 1.65 ~ 5, should use width light fixtures.

(2) select the appropriate color temperature and the lighting source whose color rendering index meet the production requirements.

(3) achieve the required uniformity of illumination: general lighting illumination uniformity of the operating area should not be less than 0.7,illumination uniformity of adjacent to the surrounding of the operating area shall not less than 0.5.

(4) meet the quality requirements of the directly lighting glare limited: the unified glare rating (UGR) according to the requirements of GB 50034-2004,which is that the generally allowed rate is 22, fine processing rate is 19.

(5) take measures to reduce the voltage fluctuations, prevent the lighting effects of voltage flicker and stroboscopic effect.

(6) lighting device shall be operating within the allowable voltage, the compensation capacitor should be used to improve the power factor where the metal halide lamps and high pressure sodium is used.

4 Industrial lighting options

How to choose the light should be based on the characteristics and requirements of production process. The LED tube light and LED high bay light should be adopted in the office and in the workshop,the metal halide lamps can be used where the height of plant is higher (6m above), the high pressure sodium lamps should be used where there is no requirements on color index.

Nowadays,the LED flood light and LED tube light is most widely used as the representatives of the decorative lighting and the home lighting in daily life,the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness is needed to illuminate,meanwhile,there a large number of factory engaging in developing and producing the LED light,Lead Lighting is just one of them,which adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light so that fully guaranteed stabe and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is Known as energy-saving and environmental protection ,login http://www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.
