Abstract

The invention relates to a modularized LED drive circuit, comprising a voltage stabilizing module, constant current modules, and a load grade mark. In the drive circuit, the voltage stabilizing module is a filter and rectifier step-down circuit, and the voltage stabilizing module gets access to alternating current and outputs direct current with a voltage of 12V to 60V. According to the load grade mark and a number of LED lamps that need to be loaded, the number of the constant current modules is set. An output end of the voltage stabilizing module is in parallel with each constant current module. The constant current module is provided with series interfaces to connect in series with a plurality of external LED lamps. According to the above scheme, through a combination of the filter and rectifier step-down circuit and the circuits of the constant current modules in the common LED drive circuit, the modularized LED drive is achieved, and the combination is beneficial to reducing a development period of an end product. The drive circuit reduces maintenance costs, greatly enhances using effects of users, and has high economic benefits.
