The excitation type drain electrode driving system for the blue light LED lamp is characterized in that a beam excitation type logic amplification circuit is connected between the partial voltage switch circuit and the power amplification circuit in series. The non-linear triggering circuit, the power amplification circuit and the beam excitation type logic amplification circuit are used jointly, the non-linearity characteristic of the non-linear triggering circuit is guaranteed, safe and reliable trigger voltage can be provided for the power amplification circuit, interference of electromagnetic pulse can be obviously lowered, and stable performance of the power amplification circuit is guaranteed.

Description

technical field [0001] The invention relates to an LED drive circuit, in particular to an excitation type drain drive 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...
