Abstract

The invention discloses an LED driving circuit comprising a power supply circuit, a driving circuit, an LED module, a switch module, a constant current driving module and a control module. The drivingcircuit comprises an overload protection module, a rectifier module and a constant current module. The overload protection module is connected with the output end of the power supply circuit. The overload protection module is sequentially connected with the rectifier module and the constant current module. The constant current module comprises a constant current sub-module, a peak elimination module, an output isolation module and an output filter module. The constant current sub-module is connected with the output end of the rectifier module. The output end of the driving circuit is connected with the LED module. The power supply circuit comprises a storage battery unit, a BMS battery management system, a bidirectional converter unit and a commercial power unit. The BMS battery management system is connected with the storage battery unit and used for collecting the state parameters of the storage battery unit. The rectifier module and the constant current module are arranged to eliminate the influence of electromagnetic interference, and peak elimination and output filtering are used so that the ripple current is completely eliminated and the stroboscopic phenomenon of the LED module is also eliminated.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to an LED driving circuit. Background technique [0002] With the different application requirements of LEDs in various fields, LED drive circuits are also constantly improving and developing. Compared with traditional light sources, LEDs have significant advantages: LED luminescence is a process in which electrical energy is directly converted into light. Compared with traditional light sources, such as incandescent lamps, which first convert electric energy into heat energy, and then convert heat energy into light energy, LED has the advantages of high light efficiency and energy saving. In addition, under appropriate driving conditions, LED lights have long life, etc. features. At the same time, LED has the advantages of light-emitting response block, changeable light source shape, and flexible color control. Compared with traditional light sources, LED has good low-temper...
