LIGHT SOURCE APPARATUS AND PROJECTOR HAVING LIGHT SOURCE APPARATUS

摘要

A light source apparatus comprising light sources including laser diodes and collimating lenses, a condenser lens, and a transmissive phosphor wheel. The collimating lens and laser diode are placed with a first shift such that an optical axis of the collimating lens is shifted from that of light from said laser diode in the direction perpendicular thereto. The laser diodes include a first laser or second diode where a direction of a short axis of a condensed shape is placed in a first or second direction, and a second laser diode where a direction of a short axis of a condensed shape is placed in a second direction. The collimating lenses corresponding to said first laser diode and the second laser diode are placed with a second shift in a direction of the optical axis of said collimating lens.

1. A light source apparatus, comprising:
a plurality of light sources each including a laser diode and a collimating lens which corresponds to said laser diode; a condenser lens which condenses lights emitted from said light sources; and a phosphor wheel having a phosphor, said phosphor wheel transmitting a light which is emitted from said condenser lens, wherein at least in a part of said plurality of light sources, said collimating lens and said laser diode are placed with a first shift such that an optical axis of said collimating lens is shifted from an optical axis of a light emitted from said laser diode in the direction perpendicular to the optical axis of the emitted light, wherein said laser diodes include a first laser diode in which a direction of a short axis of a condensed shape thereof is placed in a first direction, and a second laser diode in which a direction of a short axis of a condensed shape thereof is placed in a second direction which is different from the first direction, and wherein said collimating lens which corresponds to said first laser diode and said collimating lens which corresponds to said second laser diode are placed with a second shift in a direction of the optical axis of said collimating lens.
