In recent years, the CE marks are more and more widely used in the market of European economic area (Member states of the European Union and the European Free Trade association, except Switzerland). More customs of different countries set out the requirements of CE certification for imported products. Exporter will be in trouble as well as unnecessary loss if their shipping goods don’t have CE c...
LED package is mainly to provide a platform for LED chips, so that LED chips have better performance of light, electricity and heat. Good packaging can make LEDs have better luminous efficiency and good heat dissipation environment, and good heat dissipation environment can enhance LEDs. The service life. LED packaging technology is mainly built on five main considerations, namely optical extracti...
High frequency fluorescent lamp came out in 1990. Fine tube, small current and high power is the distinct features. Because of the above design structure, high frequency current working, electronic ballast with low power consumption, the work system of this high frequency fluorescent lamp is superior to the traditional lamp on the aspect of lighting effect and photometric. How to measure the chara...
LED has the features of long time. According to different power drivers and use conditions, the life of LED can be up to 50,000 hours or more. LED will not extinguish directly like other light source but decay gradually. Therefore, luminous decay will lead to output low light after long time use, which will make products not meet requirements. And how to use TM-21 to estimate LED luminaries life? ...
According to the requirements of the LM-79 optical testing standards applicable to the widest range in the world, although there are many photometric measurements for light sources and lamps are available, but these standards are dedicated to the measurements for light sources and lamps. Because the form of current SSL products are lamps or luminaires, and LED in the luminaires is not easy to be ...
Due to the LED solid-state lighting products have good luminous efficiency, long life and high reliability unique characteristics, so it’s became more popular by markets and customers. But at the same time, the LED solid lighting have fast response characteristics, it haven’t thermal inertia and afterglow effects, like traditional lamps, so it have big influence by current fluctuations, the cu...
Energy Star certification (Energy Star certification) is a certification which can adapt to the requirements of the United States Energy Department. In addition to UL, FCC certification, it is the most popular certification of lighting products to enter the United States market. UL reflects the goods safety performance, FCC reflects the electromagnetic compatibility of products, while the Star En...
Comparing with traditional fluorescent lamp, the LED tube have high light effects, low power consume, long life time and stable luminous efficiency advantages etc. At the same time, for the LED tube performance testing is became more simple, in recent years more and more customers has chosen the LED tube to replace fluorescent lamp. Due to the main lighting products are consist of traditional fluo...
With 4.0 concepts emerged on the industry, the traditional mind of manufacturing is experiencing unprecedented impact, integration and upgrade of industrialization and information will be the main theme of the transformation for production structure in the future. LED industry as a huge lighting market, in the new historical situation, only LED intelligent road can go farther. For now, the direct...
