ABSTRACT:
A light source unit includes a mirror tunnel which has a prism-like shape and whose external sides are formed to taper, and a light source which includes a light emitting device and which is disposed on a side of the mirror tunnel. A reflecting mirror is provided at a first end face of the mirror tunnel, and a second end face of the mirror tunnel, that lies on an opposite side from the first end face, is an end face from which light is emitted, and has an area wider than that of the first end face. The light emitting device of the light source includes red LED's, blue LED's and green LED's, and the LED's are disposed on the side of the mirror tunnel such that the LED's of the same color do not lie adjacent to each other in a longitudinal direction of the mirror tunnel and a direction which is at right angles to the longitudinal direction.
