Sinrace Power Supply Technology (Shenzhen) Co., Ltd.

LED light principle is let electrical energy converted to light energy,that is put the current to semiconductor compound,through the combination of electronic and electrical hole, the excess energy will release in the form of light,and achieve the effect of light. Because light brightness decision by the current size and brightness, the stronger of the LED current, the light brighter. therefore,the current stability will affect the quality of LED light, generally the method to control LED current will adopt the way of fixed supply voltage,and adjust the LED current strength by the way of resistance, this is the lowest cost solutions.
　　
2. In 2015 LED drive IC market revenue reached nearly $3.5 billion

According to the market research organization prediction from Strategies Unlimited, LED drive (LED driver) IC market revenue scale change the nearly $2 billion in 2010 to nearly $3.5 billion in 2015, the average annual growth rate is 12% during the composite (compound annual growth farther CAGR). The agency points out, the LED backlighting required LED driver IC, is the main power of the growth in the market, the popular applications include side light type television and display, LED lighting is the next potential applications.

    But the Strategies Unlimited also pointed out, the LED driver market scale at the same time, with the price of a product may decline; In addition, although AC-LED products needed the narrow number of the driver IC, and even don't need drive IC, but it will don't make significant revenue impact in the forecast period of market, and even help to speed up the LED lighting products market penetration growth. Strategies Unlimited estimates the market growth rates of LED lighting drive IC, in 2010 ~ 2015, it can reach 40%;  the challenges of this field technology, including adjustable light (dimming) technology, power-efficient, power factor (power factor) and price.
