Title:
LED LIGHT SOURCE MODULE DIRECTLY USING METAL HEAT SINK AS POSITIVE/NEGATIVE ELECTRODE CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2017/167316
Kind Code:
A1
Abstract:
An LED light source module directly using a metal heat sink as a positive/negative electrode circuit. In the LED light source module, LED chips (C) are directly and fixedly connected to the metal heat sink, the good conductivity of the metal heat sink is used, and the heat sink is divided into blocks which respectively act as circuit positive/negative electrodes, according to circuit design requirements, for connecting the chips (C) and connecting to an external circuit to form a complete circuit. Other PCB circuits need not be designed and added. The LED light source module significantly facilitates circuit design, reduces production processes, and decreases production costs.
