ABSTRACT:
To provide a projector using a light source device that is rapidly and reliably turned on and can stably obtain a desired amount of light and a method of rapidly and reliably turning on a light source device of a projector.A power control unit adjusts the amplification factor of an amplifying unit for microwaves such that microwave power having a pulse form that is higher than the microwave power radiated to keep an electrodeless lamp emitting light is radiated to turn on the electrodeless lamp. Therefore, a microwave having predetermined power is radiated to the electrodeless lamp at once.
