Power IC fierce fighting LED drive into new hope

With the increasing depletion of the earth's resources, all sectors of environmental protection and energy saving issues of increasing importance, the implementation of the science and technology industry, it is the demand for more energy saving technology products, so the role of power IC play an important role. In addition, it is from the point of view of energy saving and environmental protection, led LED backlight, lighting and panel market prospects are promising, but also attract many analog IC industry have invested in the field of LED driver IC.

First of all, let us examine the market prospects of LED, according to a comprehensive report of the topology Research Institute for 2008 days before the trend of science and technology industry pointed out that in the demands of environmental protection and energy conservation today, four yuan LED and high brightness red, orange, blue and green LED have been published, white LED has become one of the highest the voice of green energy. The topology Research Institute estimated that in 2008 global white LED application value of about $8 billion, annual growth rate of 16.6%, showing modest growth in the year, mainly from the mobile phone and the output of automobile and LED light source, the mobile phone market is still the largest application areas, 7~10 inch LED backlight panel, special applications (such as LED lamps) increased and the proportion of the use of the car inside and outside the LED, notebook computer panel backlight and commercial lighting LED stable trend.

In addition, with the 2008 Beijing Olympics, driven by new construction and consumer electronics industry demand, coupled with environmental protection and energy saving policies play white LED industry push, LED market will become a a hotly contested spot, the application of LED products to larger size LCD TV, car LED, large billboards, notebook computer, LED backlight lamps, indoor outside the building decoration, and even the general lighting market.

As governments, relevant organizations and industry to actively develop environmentally friendly, energy saving, energy-saving ideas and application products, LED industry with a wide range of applications advantages to catch up, the traditional light source will be faced with being "marginalized" crisis, especially LED lighting will become the product of high brightness LED fastest growing.

The topology research institute further pointed out that in 2008, due to a substantial application of digital photo frame, low-cost computer, notebook computer and LCD TV backlight and Beijing Olympic effect, increase the proportion of white LED in the infiltration of consumer electronic products and indoor lighting, white LED production cost is expected to decline, will help accelerate shorten the LED spread.

LED drive market prospects can be expected, Power IC industry into

From the above trends, the LED market in 2008 and 2009 will be a key growth, so Power IC industry are actively layout LED driver IC field. Peng Peng, deputy general manager of science and technology Jian Shifang pointed out that the outlook in 2008, the main technology will still be on the LED Peng drive IC. Jian Shifang said that the company is in the LED backlight, lighting and other parts of the board are quite gains. In the backlight part, current customers have been included in South Korea and Taiwan panel makers; in the lighting part, wide cooperation with well-known Peng has lighting industry, the other in the Kanban part Guangpeng also find partners, will join in this field.

For the LED lighting market, Jian Shifang pointed out that the current brightness of LED per watt is 136 lumens, but it is estimated that by 2009, the lumen per watt will be able to increase to 300 lumens, LED lighting market will help further mature. However, this must overcome the biggest problem of LED lighting, that is, heat dissipation. However, Jian Shifang believes that with the development of technology, the heat problem should be able to get effective solution.

In the face of conversion efficiency, Jian Shifang pointed out that in the past AC conversion to DC current efficiency is not good, but Peng Peng's patented technology to launch the model A704 AC/DC converter, it can effectively improve the conversion efficiency. Jian Shifang mentioned Guangpeng another original ideas, it is called the LED Bridge, the last LED lighting series, with packaging factory cooperation, change LED and specific IC in parallel combination, thus, when the LED bulb is damaged, not to replace a string of LED, only need to change off the damaged LED can, so can greatly reduce the cost.

To solve the problem of heat dissipation, LED lighting business opportunities

Waiting for the LED lighting market to further mature, Guangpeng quite positive in LED board market development, Jian Shifang pointed out that the market of the product cycle is long, the relative difficulty is higher, so the Guangpeng is in cooperation with third parties together into the market. Jian Shifang stressed that the main market for LED lighting will be in mainland China, therefore, for the nearest customer service, Peng Peng has been built in the FAE team in Shenzhen.

Observation of the LED lighting market, Jian Shifang believes that due to the LED lighting there is still the heat problem, so in 2008 the market size is not too large, but by 2009, estimated to 300 lumens per watt of lumens, and the traditional lighting of the price gap by 4 times now reduced to 1.5 times after the LED lighting market will obviously take off.

In view of the LED lighting market, Jia Tong Technology Marketing Director Zhang Shili also admitted that currently the company is actively research and observation of LED driver IC market. He pointed out that, on the whole, in the backlight market, due to the large number of competitors, so even if you can get into Baoshan, but empty handed back to the people there should be a lot. As for the lighting market segment, Zhang Shili believes that the U.S. Energy Star (Energy Star) has yet to be further specification. It is understood that the American energy star in September 2007 for LED lighting launched the 1.1 version of the specification, the specification includes home auxiliary lighting, such as lamps, lamp, lamp block, small garden stairs
