PURPOSE: A light source device using RGB light emitting diodes is provided to determine desired wavelength bands with a manual control knob or controller by simultaneously or selectively outputting all wavelength bands corresponding to red, green, blue, and white. CONSTITUTION: A light source device comprises an RGBW LED(Light Emitting Diode) module(A) comprising red, green, blue, and white LEDs, a rod lens(B) collecting and mixing color lights emitted from the LEDs, a color sensor detecting the wavelength band of color lights emitted from the RGBW LED module, and a cooling device(C) cooling heat emitted from the RGBW LEDs from the rear side of the RGBW LED module. |
