Abstract
A light source device includes heat releasing fins for cooling a blue light emitting diode (LED), a red LED, and a green LED, respectively, which are located next to each other in a direction in which a cooling fan blows air. A space formed between an upper surface of an optical unit and the heat releasing fins enable cooling air of the cooling fan to pass through the space.
