An RGB-LED(Red, Green, Blue Light Emitting Diode) module is provided to reduce total weight of the module and to configure a thinner and simplifier module by using different powers at each module and providing the powers with two lines. A constant current unit(29) provides a constant current. RGB-LED Modules(30,31,32) are comprised of plural RGB-LEDs. An R-mapping voltage unit(34) generates an R-mapping voltage for driving the R-LED module. An R-driving unit(33) is switched to be turned on by the mapping voltage to drive the R-LED module. A G-mapping voltage unit(36) generates a G-mapping voltage for driving the G-LED module. A G-driving unit(35) is switched to be turned on by the G-mapping voltage to drive the G-LED module. A B-mapping voltage unit(38) generates a B-mapping voltage driving the B-LED module. A B-driving unit(37) is switched to be turned on by the B-mapping voltage to drive the B-LED module.
