A lamp-driven integrated LED packaging structure

Abstract

The utility model relates to LED packaging technical field, concretely relates to a lamp drive all -in -one's LED packaging structure. It includes: as the substrate's PCB board, a plurality of packaging integrated module, including the lamp pearl of PCB board front packaging and the drive chip of PCB board back packaging, every red green blue three lamp pearl constitutes a pixel point, the lamp pearl with the solder pad connection of PCB board back, and the solder pad is connected with the signal end of drive IC through PCB wiring, the drive chip is used for providing matching current for all lamp pearl and receiving the input signal of external controller and resolving into three channel's PWM control signal to independently control every the red green blue three color brightness of pixel point, solved the problem that traditional LED packaging yield is low, cost is high, maintenance is difficult, the problem of low integrated level, high power consumption.
