LED technology development needs drive technology development. Current LED market was 100 million U.S. dollars, the next 3 to 5 years will expand more than 10 times.
For the Chinese market, National Semiconductor Asia Pacific market, citing iSuppli, China LED Driver Ic market forecast the global economy and the electronics industry settlement recession, China’s LED driver, Ic market was only up 1% from 2008 of 115.3 million U.S. dollars up to 1.16s billion in 2009. However, growth will accelerate to 9.6% in 2010, it will reach to 127.7 million U.S. dollars. Chinese LED market is expected to reach 139 million U.S. dollars in 2013.
With the global economy to gradually return to warm, in 2009 recession in the automotive, communications with the LED driver IC market is expected to stabilize, industrial / lighting market is also two-digit growth in space, as the information used in consumer electronics with the market, jump will occur growth forecast Ic 2010 LED driver market, will be expanded to 3.41 billion, compared to 2.7 billion in 2009, a growth of 26.0%.
However, LED drive power demand is also rising. senior product manager BillWeiss that, LED Driver Ic trend and characteristics of technological development as follows: high reliability, high efficiency, high power factor, adjustable light and small size.
The LED driver specific technical features that many manufacturers focus on:
1.LED luminous efficiency of the promotion:
2. LED module thermal management: good heat treatment. Whether for life or LED color rendering, can supply a better state;
3. Conversion efficiency: Based on the purpose of saving energy and reducing carbon, it can provide a high degree of use of public power plants – factors that enhance the power conversion is also one of the key directions:
4. Reliability: In the materials and circuit design option Much ink: 5.LED backlight: Technically, the main use of LED backlighting made the challenge are: LED current matching in multi-pieces of string. Including power, protection circuits, dimming when the noise and so on.
The rapid development of LED lighting, annual growth rate of more than 60%, with the continuous improvement of LED luminescence efficiency, packaging technology continues to improve, driven land can and increased life expectancy, LED lighting technology in the next 5 years will gradually into millions of households.
Environmental issues around the world, the trend of increasing importance, LED lighting industry will play an important role, its main application is for indoor and outdoor lighting and street lights high power products. It is reported that the global lighting market in 2009 about 121.9 billion U.S. dollars, LED only 0.5%, which shows considerable potential for its future.
