Abstract

See full text

A projector includes an apparatus casing, a light source module, a flow generating device, a sensing module, and a power module. The light source module is disposed inside the apparatus casing and includes a light-emitting part and a lampshade surrounding the light-emitting part. The flow generating device can generate an air flow for dissipating heat by the light source module. The sensing module is disposed in the apparatus casing and includes a thermo-sensitive component disposed near the lampshade and located in a flowing path of the air flow. The power module is disposed in the apparatus casing and electrically connected to the light source module and the sensing module. The power module selectively stops powering the light source module according to an electric parameter of the thermo-sensitive component. Thereby, the invention protects the projector from being overheated by use of the thermo-sensitivity of the thermo-sensitive component.
