ABSTRACT:
In a rod-like member2through which light can pass, one end2ais formed as a light exit portion, other surface than this one end2ais formed as a light reflecting surface2band a plurality of LEDs3is disposed on the longitudinal direction side surface of the rod-like member2of this reflection surface2balong this longitudinal direction to thereby construct a light source apparatus1. Thus, a light source with high luminance and high focusing efficiency suitable for use with a projection type display apparatus or the like can be realized by using LEDs.
