Abstract
A light source apparatus includes a light source emitting light, an optical deflection element deflecting and exciting the emitted light, and a light conversion member cyclically outputting source light components having a plurality of hues in accordance with irradiation positions in a time-sharing manner based on the irradiation using the light deflected by the optical deflection element.
Claims7
A light source apparatus comprising:
- a light source which emits light;
- an optical deflection element which deflects and excites the emitted light;
- and
- a light conversion member which cyclically outputs source light components having a plurality of hues in accordance with irradiation positions in a time-sharing manner based on the irradiation using the light deflected by the optical deflection element.
1 more element
A light source control method comprising:
- a step of driving an optical deflection element which defects light from a light source with a predetermined frequency to excite light exiting therefrom with respect to a light conversion member which selectively outputs source light components having a plurality of hues in accordance with each position of light to be applied;
- a step of irradiating the light conversion member with the exiting light;
- and
- a step of cyclically outputting the source light components having the plurality of hues from the light conversion member in a time-sharing manner.

A projector apparatus comprising:
- a light source unit including:
- a light source which emits light;
- an optical deflection element which deflects and excites the emitted light;
- and a light conversion member which cyclically outputs source light components having a plurality of hues in accordance with irradiation positions in a time-sharing manner based on the irradiation using the light deflected by the optical deflection element;
- a display element;
- a light guide optical unit which guides the light from the light source unit to the display element;
- a projection optical unit which projects an image exiting from the display element;
- and
- a control unit which controls the light source unit and the display element.
