<p>PURPOSE: An RGB color LED module driven with AC power is provided to reduce a manufacturing cost and a size of a product by rectifying the input power from the AC to the power for driving the RGB LED. CONSTITUTION: A bridge diode rectification circuit(10) receives the AC power, converts the AC power to the power for driving an RGB LED, and outputs the converted power. A module color control circuit(20) controls and sets the color of the lighting. A plurality of LEDs for emitting the R,G, and B light by the power inputted through the module color control circuit are arranged. A plurality of R LED groups(31) emit the red light. The plurality of G LED groups(32) emit the green light. The plurality of B LED groups(33) emit the blue light.</p> |
