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.

LED light source is known as long life, energy saving, easy application, low cost, and thus it will receive a flood of applications in home lighting, OSRAM optical semiconductor company surveyed that the global annual shipments of the home lighting lamp was about 50 billion in 2008,.

LED light source technology matures, the lumens per watt LED grow rapidly, prompting its diminishing prices. Taking the 1WLED light, for example, the price in the spring of 2008 is one-third of the price of the spring of 2006, the spring of 2009 has be reduced to one quarter of 2006.

The mass market and a steady growth in demand of the LED green lighting for several years will be super tsunami of the IC industry following VCD, DVD, mobile phones, MP3 on the consumer electronics market!

The superiority of high energy saving, long life and good for environmental protection of the LED lamps is being universally recognized.

1.LED High energy: DC drive, ultra-low power consumption (single tube is 0.03 ~ 1W) the electro-optical power conversion is close to 30%, the same lighting effects is 10% more than that of the traditional energy sources.

2.LED Long life: LED light source is called as longevity lamps. It is the solid cold light source, epoxy resin, there is nearly no loose parts in the light body, and there is no filament that is easy to burn, heat deposition, the fast light fades and other shortcomings, the service life is up to 50,000 hours, the life is 5 times longer than that of the conventional light sources.

3.LED is good for environmental protection: LED is a green light, the environmental benefits is better. The spectra contains no ultraviolet and infrared, low in calories and no flicker, no radiation, and recyclable waste, no pollution, no mercury elements, cold light source, safe touch, typical of the green lighting.

The work characteristics of the LED light

The VF used for lighting of the LED lighting source is of low voltages, which is normally 2.75 ~ 3.8V, IF is generally 15 ~ 1,400 mA. Therefore, the output voltage of the LED driver IC is VFxN or VFx1, IF keep the constant that is at 15 ~ 1,400 mA. There are two kinds of power that are the small power (IF is 15 ~ 20mA) and high power (IF is greater than 200mA) used for the LED light source. The Small power LED is mostly used to produce LED tube light, decorative lights, grille light. The big Power LED is used for household lighting, LED flood light, underwater lights, wall lights, street lamps, tunnel lights, car lights. Power of the LED light source is the device that is suitable for the low voltage, high current drive, the luminous intensity is determined by the current flowing through the LED. the LED light attenuation is caused by the General Assembly Current, the too small current will affect LED luminous intensity. Therefore, LED driver needs to provide constant current power to ensure the safety of high power LED, and to achieve the desired luminous intensity. In the field of LED lighting, the correct choice of LED driver IC is essential to reflect the characteristics of energy saving and long life of LED lights,. Not a good driver IC matched, LED lighting advantage can not be reflected.

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.

With the acceleration of urban construction, more and more mountain are connected by the tunnel , we have been concerned about how to choose a good tunnel lighting, as the tunnel is semi-closed environment, we must choose the lamp which can properly light up the tunnel and come through the fog and have the features of the strong waterproof and rustproof ,the high-pressure sodium lamps is currently the most widely used, but with increasing demands on energy saving, plus that the light colour of the high pressure sodium and mercury lamp is narrow, the brightness is low, we begin to turn to LED tunnel lights, so, what is the difference between the LED tunnel lights and high pressure sodium in the end?

1, just from the luminous efficiency, the LED tunnel light is 90lm / w,the sodium light reach 120lm / w;

2, from the performance of through the fog, the golden yellow light of the sodium light can better through the fog, of course, which can also be replaced with warm white LED tunnel light;

3, in view of the initial investment cost, the price of the LED tunnel light is three to four times more than the sodium light;

4, as far as the saving the cost is concerned, taking into account the factors such as the power , LED lights can save more than 60 percent;

5, long life, LED tunnel lights can theoretically reach 50,000 hours or more, but limited by a variety of factors, such as lamps heat dissipation, the life of the power and so on, the life of the sodium lamp can reach 12,000 hours, considering the high cost of maintenance in the tunnel, the LED tunnel lighting is more appropriate;

Generally speaking, 100W LED lighting can completely replace 200W high pressure sodium (the specification of the sodium light is typically 250W), but we should choose the right products from the color temperature, light efficiency, heat dissipation, etc., in addition to a large number of products must be used for the project, we can make a relatively detailed investment plan to contrast,after the initial investment of the product, energy-saving performance and maintenance costs are analyzed. LED tunnel lights is better than the high sodium sodium light.

Tools / materials

Multimeter

Methods / steps

1.First, we must ensure that there is no problem with the circuit of the LED lamp in our own families, the main problem is that the switch has gone wrong , the switch is the focus of our detection.

2.Check the the power converter on the back of LED lights (that white box that is in the figure is the power converter), for this,the converter would be directly removed, and powered with a multimeter to measure the voltage or current, if the power converter is damaged,which can be directly purchased for the replacement, it is generally very cheap.

3.If there is no problem with the LED power converter,then we can cut the multimeter to the voltage output gear, and then place in the corresponding positive and negative point of the LED lamp to look up it will be lit or not. Replace it If it is can’t be lightened up.

4.Generally speaking, after the above three steps,60% of the LED lights problem can be solved, so our LED lights should be able to re-radiate the glory.

Precautions

Before we purchase the energy-saving LED lights, there are several things you need to know. For consumers who do not understand the market, a qualified energy-saving lamps must be achieve high standards in the brightness, color and energy use, in addition the content of the mercy must not be exceeded tribute. After tested for more than 3,000 hours, the United States, “Consumer Reports’ released by the United States found that LED bulbs and fluorescent bulbs, LED light bulb, are among the most energy-efficient lamps.

Moreover, we can for look the manufacturer’s information online. We should check the quality of light sense in store. No matter which one you choose, please remember to buy a few to test at home. Besides, pay attention to the following aspects when purchasing and using the lighting:

First, consider configuring

When replacing the lighting, we’d better choose those which are the same as the size of the original to ensure that it can meet its original configuration. The dimmer must be use with the dimmable light fixtures and outdoor lights such as the LED flood light that are designed specifically for outdoor. By rating value, we can understand the purpose recommended by the manufacturer, meanwhile check more detailed information of the bulb specification.

Second, observe the lumen

Lumen is the illuminance (brightness) unit. In suitable brightness, choose the bulb whose power is the lowest(the wattage indicates the energy consumption). Brightness is in lumens (beam energy units) as a unit. Buy LED or fluorescent lamps (This model is generally used in lamps or other configuration, known as A-type lamps), you can use a 450 lumens of light bulb to replace a 40 watt bulb, corresponding to 800 lumens instead of 60 watts, 1100 lumens alternate the 75 watts, 1600 lumens or even higher replace 75-watt bulb. For the R30 floodlight, the bulbs whose lumens is more than 10 times than the original wattage need to be found, such as the 65-watt bulb is equal to the 650-watt floodlights.

Third, choose the color

Warm light is very lovable, so which is widely used in the most family, so Kelvin temperature (temperature unit) is lower. Standard incandescent will produce a warm yellow light, the color temperature is about 2700 Kelvin (K) or so. If you like this warm colors, then select the LED lights, you can choose LED lights that is around 2700K. If you prefer the cool, bright white light, you can choose 3500K to 4100K bulbs. Between the 5000K and 6500K, the light will be close to natural light or sunlight.

Fourth, pay attention to CRI

CRI is the color rendering index, which is to tell you the color change. CRI ranges from 0 to 100, the 100 incandescent bulbs is close to the sun during the day. The CRI of the Indoor lamp is generally recommended to 80, within 5 points difference is negligible. Comparing bulbs, you can check the different CRI values at the same Kelvin temperature.

Fifth, away from children

As a user, do not view any high-powered light, or put them anywhere the children can closely look up – High Power Flashlight, LED lights, or other similar product is not a toy, please let these things away from children who are not in custody . Also, if you want to install LED lights in public places, consider installing warning notices. At home and in the workplace, avoid cold white LED lights, especially the lights whose surface brightness is close to 10,000 cd/m2.

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.

Because LED tube light is known as energy saving and high brightness, moreover the prices have been gradually reduced, so LED tube light enjoys a increasing popularity, but there are vastly different LED tube light on the market, which one is better in the end,then that let me share with you!

Tools / materials

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.

Precautions

The advantages of the LED tube:

High brightness, low power, energy-saving effect is obvious.

Start fast, flicker-free when started.

“Visible light communication” as new communication technologies taking advantage of the LED has been closely watched , which is about to enter the practical stage. The LAMP SERVE company which is a venture in Naha Okinawa Japan will begin to conduct the world’s first outdoor demonstration experiments to start establishing the high-speed communications technologies in September. If successfully developed, which will be expected to show their talents in Africa and Asia and the emerging market countries that is lack of the communication infrastructure.

It is reported that LAMP SERVE has found the local cooperative enterprises, the underlying technology and the hardware is provided by Japan, Estonian is responsible for the development of software, etc., culminating the visible light communication transceiver has been successfully developed for in Estonia.

Toyoko Ichiro who is the president of the LAMP SERVE said that one street light only currently takes 100,000 yen or so to lay the equipment that is used to send and receive the communications. Allegedly the communication speed usually can be granted at 100 megabits per second or so.

LAMP SERVE May this year can be carried out outdoors visible light communication technology was patented. Scheduled in September tested first in Estonia, followed by empirical tests are carried out in Okinawa.

LAMP SERVE conceived that the using the street lights as one of the visible light communication tools. That is the LED is installed on a street light, it also have communication capabilities. Data have demonstrated that, at present visible light communication can be done between about 200 meters, LAMP SERVE idea is to use the street light as the infrastructure to achieve high-speed communications.

Thus, the communication combining with LED outdoor lighting provides us with the more convenient service, later when we walk in the street, with the help of LED street lights and other LED outdoor lighting, we can real-time communication, LED lighting is indeed relative to traditional lighting, in addition the energy saving lighting brings us the better experience, but also the semiconductor technology applying in other areas gives our lives more convenient service,now LED outdoor lighting such as LED flood light, LED tunnel light have gradually replace the traditional lighting and stepped into our lives,there are a large number of LED flood light and LED tunnel light that have been adopted in the square and stadiums, parks, commercial buildings, fountains, road and rail tunnel , while there are also some professional manufacturer specializing in researching and producing the LED light, Lead lighting’s more professional R & D and production teams have been using high quality materials to focus on producing affordable LED lighting to meet the public demand, if you want to know more LED tunnel light,please Log in http://www.lead-lighting.com/products/bid32-1.htm or return to the homepage for other LED lighting.

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 choosing LED lamps, it is undoubtedly that we take into account the more energy-efficient, environmentally friendly, no flicker, but in the case of long-term use, LED lamps also easily suffer from wear and tear, plus some wrong operation, the LED lamps can be easily damaged. the LED lamps as the third generation of high-tech energy-saving lighting also need a good maintenance in order to maximize the effectiveness and have a longer service life. With the popularity of LED lighting in 2013, more and more consumers also raise issues about the small series of LED maintenance, the experts have invited to answer it.

What circumstances make the LED lamps be bad?

A) poor quality of the LED lamps tend to be broken,recognize the quality assurance brand to buy.

2) the LED lamps that are not properly used in accordance with product instructions prone to failure, there is a risk.

3) When used,the excessive current exceeds the rated current of LED lamps, some components of the LED driver power will result in the breakdown or burned and other hazards.

4) LED lamps “mist” issue, after the pointed candle light, bulb lights, LED flood light and other lights is lightened up for a while,there is water droplets on the inner wall of housing, which is the mist phenomenon. LED lamps are generally the assembly of several different materials, for instant,the heat part of the lamp cup is made of the metal, the lampshade is made of the plastic; lamps generate a certain amount of heat at work, different materials with different coefficients of thermal expansion, a gap is generated at the inlet in the bonding of different materials after extensive use; when used in an environment where the humidity is relatively large, the inside and outside of the lampshade is of different temperature, the gases heated of the internal lamp shade is cooled, if this gas contains more water vapor, which will produce the phenomenon of water
fog and water droplets, continue to light for some time, this phenomenon will disappear. Therefore, humid environment is also the factor affecting the LED lamp life.

LED use rules and methods for maintenance:

First, having bought the lamps, not busy installing, we should carefully read the installation instructions, and then follow the installation instructions to install the lighting, otherwise there may be dangerous.

Second, when cleaning and maintain the LED lamp, do not change the structure of light, do not arbitrarily change the lamp parts, having maintained, we should installed the lamp as-is, not to leave and wrongly install the lighting components;

Fourth, try not to frequently turn on and off when using the lamps, although resistance switching times of the LED light are 18 times more than those of the ordinary fluorescent lamp, but too often still affect the life of the internal electronic components of the LED lights, thus affecting the lamp life.

Five, in particular, note that the ordinary LED lamps should be avoided using in wet environments, except special LED lamps,. , Humid environment will affect the electronic components of the LED lamp driver power, electronic components is affected by damp, which will shorten the lamp life.

Therefore, moisture-proof is the key of maintaining the lighting, especially the LED light lamp in the bathroom, the bathroom and the kitchen stove must be installed dampness shade to prevent moisture ingress, corrosion damage or leakage so that avoid short circuit.

Finally, it is best not to use water to clean LED lights, just use a dry cloth that is dipped in water to wipe, if you accidentally hit the water,then try to dry, avoid immediately wiping with a wet cloth after the lights is lightened up.

Warm TIPS:

1) LED lights can not be used in the circuit of the ordinary lamp dimmer, delay switch, sensor switch.

2) Avoid using in high temperature and humidity environments

3) LED internal lighting is mainly supply-driven, recommend non-professionals do not self-handling assembly, in order to avoid electric shock hazard.

4) LED lighting lamps are generally used in the ambient temperature of 5 ~ 40  circumstances.

5) the metal part of the LED lighting can not be free to use polish powder chemicals.

6) properly use the dry cloth or duster suitably to clean the dust behind the LED lighting.

Having known how to maintain the LED light,beyond doubt, choosing the excellent enterprise specializing in researching and manufacturing LED lighting is also the key. Fortunately,there are a large number of excellent manufacturer engaging in manufacturing and researching the LED light,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.
