Abstract
A lighting apparatus for a projector comprises a control module, a lamp driver and a transient voltage suppression circuit, in which the control module is used for generating a lighting signal, the lamp driver is used for receiving the lighting signal and controlling a lamp according to the lighting signal, and the transient voltage suppression circuit is disposed between the control module and the lamp driver, used for transmitting said lighting signal to the lamp driver and attenuating a high transient voltage generated at the instant the lamp driver lights up the lamp. The present invention is used to lower the high transient voltage through the transient voltage suppression circuit. Whereby, the control module is protected and the stability of the projector is further enhanced.
