Epistar promotes Co-activation Service, adopts DoB with HV chips to win over lighting brands
HV DOB is popular in the market
Due to the demand aforementioned, Epistar currently relies on Co-activation Service to mainly promote driver on board (DoB) solutions with high-voltage (HV) chips. The one big advantage of HV chips is their ability to operate under HV direct current, hence in the process of turning alternative current (AC) into direct current (DC) there is no need to dramatically lower the voltage. This also means the chip does not require expensive drivers but can rely on linear driver circuits. In fact, in the 2014 Frankfurt Light + Building exhibition, some of Epistar’s major customers such as Philips and other Europe- and US-based firms showcased HV linear lighting products.
The DoB technology is to package power drivers directly onto the circuit board which can help minimize the size of the light source. This means the integration of HV chips into the DoB can greatly lower BoM costs and simplify designs. The DoB module introduced by the Co-activation Service provided by Epistar and its fellow partners can be immediately used after the lighting fixture firm takes delivery and puts two screws on it. This greatly lowers the entry barriers faced by traditional lighting fixture firms in the LED lighting market, and therefore this solution is quite popular.
