Description

technical field [0001] The invention relates to an LED driving circuit, in particular to a drain driving system for a blue LED lamp. Background technique [0002] At present, due to the characteristics of low energy consumption, long service life, safety and environmental protection, LED lamps have become one of the mainstream products for people's living lighting. Since the LED lamp is different from the traditional incandescent lamp, it needs to be driven by a dedicated driving circuit. However, due to the unreasonable design structure of the drain driving circuit widely used by people at present, the current drain driving circuit has defects such as high energy consumption, large current noise, and long start-up time. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of high energy consumption, large current noise and long start-up time in the current drain drive circuit, and provide a reasonable structural design, which...
