Problems solved by technology

However, this will greatly increase the size of the projector and generate excessive noise
In addition, only installing a heat dissipation module at the rear end of the light valve without effectively cooling the front end of the light valve will cause an excessive temperature difference between the front end of the light valve and the rear end of the light valve, resulting in unexpected internal stress, making the use of the light valve Reduced lifespan

Abstract

A projector includes a light source, an optical engine module, and a projection lens. The light source is configured for providing an illumination beam. The optical engine module includes a light valve, a casing, and a heat conducting structure. The light valve is configured to convert the illumination beam into an image beam. The light valve has a front portion and a rear portion opposite to each other. The casing is connected to the front portion. The heat conducting structure is disposed on the casing and at at least one side of the front portion. The projection lens is disposed on the casing and configured to project an image. The heat conducting structure is configured to dissipate heat of the casing and the front portion of the light valve.

Description

technical field [0001] The present invention relates to an optical device and an optical module, and in particular to a projector and an optical machine module. Background technique [0002] The projector uses a light valve to convert the illumination beam from the light source into an image beam, and uses a projection lens to convert the image beam into a projection beam and project it out. As the projection brightness of the projector increases, the heat generated when the light valve acts increases correspondingly. In order to prevent the light valve from overheating, the heat dissipation efficiency of the light valve will be improved by increasing the volume of the heat dissipation module and the speed of the heat dissipation fan. However, this will greatly increase the size of the projector and generate excessive noise. In addition, only installing a heat dissipation module at the rear end of the light valve without effectively cooling the front end of the light valve...
