ILLUMINATION OPTICAL SYSTEM AND PROJECTOR USING THE SAME

摘要

A projector in an illumination optical system includes a laser light source, a synchronization signal processor that converts synchronization signals that are synchronized with video signals input from outside the projector into video signals to be used inside the projector, an LD driver that controls a lighting state of the laser light source according to the synchronization signals output from the synchronization signal processor, an LED (Light Emitting Diode) light source, an LED driver that controls a lighting state of the LED light source according to the synchronization signals output from the synchronization signal processor, a rotational state detector that detects a rotational state of a phosphor wheel, and a phosphor wheel driver that, based on a detected result of the rotational state detector, controls the rotational state of the phosphor wheel.

1. A projector in an illumination optical system, the projector comprising:
a laser light source; a synchronization signal processor that converts synchronization signals that are synchronized with video signals input from outside the projector into video signals to be used inside the projector; an LD driver that controls a lighting state of the laser light source according to the synchronization signals output from the synchronization signal processor; an LED (Light Emitting Diode) light source; an LED driver that controls a lighting state of the LED light source according to the synchronization signals output from the synchronization signal processor; a rotational state detector that detects a rotational state of a phosphor wheel; and a phosphor wheel driver that, based on a detected result of the rotational state detector, controls the rotational state of the phosphor wheel such that a color of a video signal indicated by one of the synchronization signals output by the synchronization signal processor matches a color output by the illumination optical system that indicates the rotational state of the phosphor wheel detected by the rotational state detector.
