  • Lighting apparatus for projector
    Patent number: 7514880
    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.

  • Method and apparatus for monitoring signals of a projector
    Publication number: 20060055893
    Abstract: A method and apparatus for monitoring signals of a projector includes a power supply, a signal-processing unit, a control unit, a starter and a lamp. The power supply provides the power, and then the signal-processing unit transmits the starting signal to the starter. The control unit monitors and determines if the signal is normal, and then controls the power supply and the signal-processing unit according to the signal. Therefore, the present invention can prevent the lamp from bursting, increase the safety of the users, and raises the stability of the projector.
