Original Abstract Submitted
A projector includes a light source module, a light valve, and a projecting lens. The light source module includes a light-emitting element, a light diffusion assembly, a first structural component, and a first temperature-sensing element. The light-emitting element is adapted to emit an illumination light beam. The light diffusion assembly is adapted to diffuse the illumination light beam. The light diffusion assembly has a front end and a rear end opposite to each other, the front end of the light diffusion assembly faces the light-emitting element, and the rear end of the light diffusion assembly faces the first structural component. The first temperature-sensing element is disposed on the first structural component and corresponds to the light diffusion assembly. The light valve is adapted to convert the illumination light beam from the light source module into an image light beam. The projecting lens is adapted to project the image light beam.
