Liu Xuechao, a senior technology market development engineer at Texas Instruments, said that the development of LED technology requires the development of driving technology. Today's LED market is 100 million US dollars, and will expand more than 10 times in the next 3 to 5 years.
For the Chinese market, National Semiconductor Asia Pacific Marketing Manager Li Zhiyuan quoted iSuppli's forecast for China's Led Driver IC market. As the global economy and electronics industry sink into recession, China's LED driver IC market grew by only 1% in 2009, from 2008. The $115.3 million rose to $1.16 billion. However, the growth rate in 2010 will accelerate to 9.6%, and the scale will reach 127.7 million US dollars. The LED market in China is expected to reach $139 million in 2013.
Looking forward to 2010. As the global economy gradually recovers, the LED driver IC market for automobiles and communications is expected to stabilize in 2009, and the industrial/lighting market also has a two-digit growth space. For information and consumer electronics markets, There will be jump growth. It is estimated that the global LED driver IC scale will expand to 3.41 billion in 2010, compared with 2.70 billion in 2009, with a growth rate of 26.0%.
However, the requirements for LED drive power are also increasing. According to Bill Weiss, senior product manager at pI. The development trend and characteristics of LED driver IC technology are: high reliability, high efficiency, high power factor, dimming and small size.
Li Shengtai, director of development of OzMicro Technology (China) Co., Ltd., introduced the technical characteristics of LED drivers. He said that the focus of many manufacturers is: 1. The improvement of LED luminous efficiency: 2. The thermal management of LED modules: good heat treatment . Whether it is good for LED life or color rendering; 3. Conversion efficiency: Based on the purpose of energy saving and carbon reduction, whether it can effectively utilize the power provided by public power plants - the conversion of power factor is also the key direction One: 4. Product reliability: more in the material options and circuit design: 5. LED backlight: In technology, the main challenges faced by using LED as backlight: current matching in multiple LED strings . Including power consumption, protection circuits, noise during dimming (Audiblenoiseduringdimming).
The following is a brief introduction to the hot spring technology market for LED lighting, backlighting and LED TV.
Liu Xuechao of Texas Instruments said that LED lighting is developing very rapidly, with an annual growth rate of more than 60%. With the continuous improvement of LED luminous efficiency, packaging technology continues to improve, driving land energy and life expectancy, LED lighting technology will gradually gradually in the next five years. Enter thousands of households.
02Iviicro Li Shengtai said that under the trend of increasing environmental protection issues in various countries around the world, the LED lighting industry will play a very important role. Its main applications are high-power products such as indoor and outdoor lighting and street lights. It is reported that in 2009, the global lighting market was about 121.9 billion US dollars, and LED only accounted for 0.5%, which shows that its future potential is considerable. Among them, the market size in the Asia-Pacific region is the largest, accounting for 33.7% of the world's total: 30.1% in North America and 27.4% in Europe: however. Discuss with application products. Outdoor lighting accounts for about 12%, which has considerable room for growth, especially in the Chinese market, which accounts for 38% of the world's outdoor lighting. In addition, the part that deserves attention is that the streetlight application, which is directly and quickly affected by government policies and promotion, is expected to become the first great growth in the lighting industry: it is estimated that in Europe and the United States, the global trend can be achieved in 2010. The level of 4.5 million LED street lights: and in the footsteps of international energy conservation and carbon reduction, once the standard specifications of street lamps are popular, the Chinese market is expected to occupy more than 50% of the world.
From the perspective of LED brightness, the light output of high-power LEDs has reached an important milestone of 100 lumens / w, while some manufacturers claim to have reached 120 lumens / W in the laboratory. Tony Armstrong, director of power products marketing, Linear Technology That said, this means that, in terms of efficiency, LEDs now exceed CFL (80 lumens/w). However, according to further predictions, by 2012. The LED will reach an output of 150 lumens/W. In addition, the current focus is on "green", unlike CFL, which does not contain any harmful materials.
