Hong Kong and drive the development of new LED transformer, LED lamp life extension

At present, LED lighting market is increasing rapidly, is expected in 2018 will reach $31 billion 200 million, with this opportunity, more LED technology came into being, the University of Hong Kong's first light thermoelectric unified theory and the development of new LED drivers and transformers, claimed that LED can solve the lighting for a long time and light uneven problem, and the LED lamp life can also be extended to 10 years.

The LED bulb light and heat and focus only on the interaction of three electric elements, but "light power unification" theory is the combination of light, heat, electricity and the color of the four elements, the technique can accurately adjust the lighting brightness and color temperature of LED, and the lamp bulb is reduced due to temperature and aging parts caused by uneven color.

The research unit in order to make the theory applied to the market, also developed the LED driver and the corresponding transformer. The driver is different from the liquid electrolytic vessel in the past, because the temperature effect of light output and easy, the solid electrolytic container can bear relatively large temperature, there will be uneven lighting problem. While the LED transformer is composed of iron and copper, compared with the semiconductor chip now use the loss rate is lower, and there are 85% parts can be reused, reduce electronic waste LED.

Dr. Xu Shuyuan led the research said that the new LED driver is modified at the street, in addition to color is more accurate, the LED energy saving lamp life from 3 years to more than 10 years, the new LED lamp has been applied to the outdoor lighting has been installed about 300 streetlights in Guangdong, and plans to expand the scale of installation to 8000 street lamp. Xu Shuyuan pointed out that if Hongkong can be used LED lamps, estimated to save 30% to 40% of the electricity.

The team also has a new invention, a LED can accurately adjust the lighting brightness and color temperature of the lighting intelligent system, combined with networking, use of intelligent mobile phone Bluetooth or WiFi linked LED bulb, can accurately adjust the color temperature and the light is dark, the temperature error is + 5K, compared to the market on + 300K has significantly improved. After the lamp can be used for commercial wisdom for museums and other indoor places require high temperature.
