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 .

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.

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.

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.
