Abstract

The invention discloses an LED energy-saving driving system. The LED energy-saving driving system is characterized by manly consisting of a transformer T, a control chip U2, a power supply circuit and a frequency adjustment circuit which are connected with the control chip U2, a diode D4 which has a P electrode connected with the frequency adjustment circuit and an N electrode connected with a VS pin of the control chip U2, and the like. The system, by use of a GR6953 integrated chip as a control chip and through combination with a peripheral circuit, forms a half-bridge control structure, such that starting power consumption is reduced, and the system is more energy-saving.

Description

technical field [0001] The invention relates to a drive system, in particular to an LED energy-saving drive system. 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. With the continuous improvement of people's awareness of energy saving, people's energy consumption requirements for LED drive systems are also getting higher and higher, which brings new challenges to LED drive systems. However, the traditional LED drive system consumes a lot of power when it is started, which cannot meet people's energy-saving needs. Contents of the invention [0003] The object of the present invention is to solve the defect of large power consumption during start-up of the current LED drive system, and provide an LED energy-saving drive system. [0004] The purpose of the present invention is achieved thro...
