At present, LED lighting market rapid expansion, estimated in 2018 to reach 31.2 billion U.S. dollars, with this business opportunities, more LED technology came into being, the University of Hong Kong pioneered the "Light and Power Unified" theory and research and development of new LED drivers and transformers, claiming to be able to solve the LED light bulb due to long-term use and the life of LED bulbs can also be extended to 10 years.
The previous LED bulbs focused only on light, thermal and electrical interactions, but the "Light and Power" theory is a combination of light, heat, electricity and color of the four elements, the technology can accurately adjust the LED bulb light and color temperature, and reduce the bulb due to temperature and the aging of the parts produced by the color uneven. In order to apply the theory to the market, the research unit also developed the corresponding LED driver and transformer. The driver is different from the previous liquid electrolytic container, it is easy to affect the light output because of the temperature, its solid state electrolytic vessel can withstand the huge temperature difference, also will not have the problem of uneven luminescence. And led Transformers are made of iron and copper wire, compared with the semiconductor chips now used, the loss rate is lower, and 85% of the parts can be reused, reduce led electronic waste.
