Opportunities and Challenges Facing the Trend of Intelligent LED Technology

　LED lighting with energy-saving, environmental protection, longevity, earthquake, small, fast response and so on. Currently, LED applications include backlighting, general lighting and automotive lighting of the three markets. With LED lights prices, comfort and safety become technical direction of the semiconductor lighting. In addition, the semiconductor lighting era of intelligent lighting will open. Intelligent lighting with light brightness adjustment, color temperature adjustment, light soft-start, timing control, scene settings and other functions, and to achieve a personalized, comfortable, secondary energy saving, safe and efficient requirements.

　LED lighting has many outstanding advantages: energy - DC drive, electro-optical power conversion close to 100%, the same lighting effects than traditional energy sources more than 80%; long life - life of up to 60,000 to 100,000 hours, compared to traditional light sources long life more than 10 times; more color variation - red, green, and blue color theory, under the control of computer technology to make three colors with 256 gray scale, and any mix can produce 256 -- 256 -- 256-16777216 colors; environmental protection - neither heat nor radiation, glare is small, recyclable, no mercury elements, cold light source, safe touch; high - low voltage microelectronic products, the integration of computer technology, network communications technology, image processing technology embedded control technology, semiconductor optoelectronic devices digital information products, with online programming, unlimited scalability, flexible features.

　 LED lighting is relatively higher than the price of conventional light sources, which became one of the barriers to enter the LED market. In addition, excess capacity has also led to fierce competition in the LED market. Promote the development of LED lighting market is a key driver with high brightness LED and smart LED controller. High brightness LED product designers face many design challenges, including thermal management, driver program, topology architecture and infrastructure.
