Description

High-power LED driving module

Technical field

The utility model belongs to photoelectric field, is specifically related to a kind of high-power LED driving module.

Background technology

Tradition LED (light-emitting diode) drive circuit all is special making, and the LED of different capacity needs different drive circuits, does not have versatility, and maintenance cost is high and inconvenient.

Summary of the invention

The high-power LED driving module that the utility model provides; Need not to make specially the different capacity led drive circuit, only need be with some great power LED driver modules parallel connections, just can stabilized driving high-power LED more; Have very strong flexibility and versatility, and be convenient to maintenance.

For achieving the above object; The utility model provides a kind of high-power LED driving module; Comprise several parallelly connected current stabilization drive circuits; Also comprise the power input interface of said several current stabilization drive circuits of circuit connection respectively, and several difference circuit connect the driving LED output interface of each current stabilization drive circuit.

Described current stabilization drive circuit adopts Switching Power Supply current stabilization circuit or linear current stabilization circuit, and the advantage of Switching Power Supply current stabilization circuit is that efficient is high; The advantage of linear current stabilization circuit is that circuit is simple, and price is more cheap;

When driving more powerful light-emitting diode, several high-power LED driving modules through after the parallel connection of driven for emitting lights diode output interface, are driven large-power light-emitting diodes.
