| titleOfInvention | Light source unit and projector |
| abstract | The present invention prevents deterioration due to heat of combustion of a phosphor by controlling rotation and stop of a luminescent wheel in a state in which excitation light is radiated by an excitation light source to the phosphor layer. While providing a projector that can reduce power consumption. The projector of the present invention includes a light source unit having an excitation light source, a fluorescent wheel in which a phosphor layer emitting light emitted from the excitation light source as excitation light is placed in the circumferential direction, a wheel motor for driving the fluorescent wheel, and a display. An element, a light guiding optical system for guiding the emitted light from the light source unit to the display element, a projection-side optical system for projecting the projection light generated by the display element, and an excitation light source to the phosphor layer And a motor controller for determining whether to stop or drive the wheel motor while the excitation light is being irradiated, wherein the motor controller checks the projection mode at the time of projection and the driving current flowing through the excitation light source. Switching control between stop and drive is performed. |
