Projection apparatus and method for adjusting a driving voltage of the projection apparatus

摘要

A projection apparatus and a method for adjusting a driving voltage of the projection apparatus are provided. The projection apparatus comprises an illuminant module, an output voltage control module, an illuminant driver module, and an illuminant driver management module. The output voltage control module is configured to output a driving voltage. The illuminant driver module is configured to output an illuminant voltage to the illuminant module after receiving the driving voltage. The illuminant driver management module is configured to receive the illuminant voltage and to detect a variation in the illuminant voltage. Then, the illuminant driver management module outputs a control signal to the output voltage control module according to the variation of the illuminant voltage. Finally, the output voltage control module adjusts the driving voltage according to the control signal.
