2013 (3rd) High-tech LED Lighting Exhibition Green integration brings high-order segmented constant current stroboscopic LED driver IC solution
[High-tech LED reporter/Wang Cairong] On November 25th, in the 2013 (3rd) High-tech LED Lighting Exhibition, which was successfully held at the Poly World Trade Center in Guangzhou, the company launched the Green Integrated Technology Co., Ltd. ") High-voltage segmented constant current LED driver IC solutions have been awarded to many exhibitors who have been awarded a number of invention patents.
“This solution is the first time in the industry to increase the power of constant current drive to 25W, leading the industry in the application of integrated photovoltaic modules. Taking the four-stage linear constant current scheme commonly used in the market as an example, the efficiency of lamps is generally below 85%. The IC can drive up to 9W applications, and there will be problems such as 100Hz strobe and low wick utilization.†Chen Heng, general manager of green integration of the disc, said that the company’s SDS3108 series of high-end points was introduced at the current high-tech LED lighting exhibition. The segment constant current chip will completely solve the above bottleneck.
According to Chen Hengyu, the "high-order segmentation" technology adopts a control scheme in which N-type switches and P-type switches cooperate with each other, and realizes twelve-segment linear constant current drive with only a small cost cost, and heat dissipation. The power is reduced by 60% compared to the four-stage linear constant current chip, and the power efficiency is up to a record 93%, providing a solid platform for the application of "dynamic configuration" and "capacitor filling" technologies.
