Description

technical field [0001] The invention relates to an LED system, in particular to a two-stage low-pass filter amplification LED voltage stabilization system based on linear drive. Background technique [0002] LED is called the fourth-generation lighting source or green light source. It has the characteristics of energy saving, environmental protection, long life, and small size. It is widely used in various indications, displays, decorations, backlights, general lighting, and urban night scenes. [0003] In large shopping malls or supermarkets, in order to achieve better lighting effects, many LED lights are often used at the same time, which has high requirements for the LED drive system. The output power of the current LED system is not high, which cannot meet the needs of some large supermarkets. Contents of the invention [0004] The purpose of the present invention is to overcome the defect that the output power of the LED system is not high enough to meet the needs o...
