Multifunctional constant current module for high power LED

The utility model relates to a pulse constant current module for LED illumination, which is composed of a controllable current unit, a sampling comparison unit, an amplifying and adjusting unit.

With the amplitude of the output is stable and adjustable, and can realize the ON / OFF utility function in a variety of control circuit, constant current module and solves various rectifier power output is DC power consumption during the operation, the problem of low efficiency of energy conversion, it is especially suitable for LED lamps used in a variety of different fields.
