Light machine module and projector

Abstract

The invention provides a light machine module and a projector. The light machine module comprises a shell, an assembly part, a light valve and a first heat exchange assembly, wherein the shell is provided with an assembly port; the assembly part is provided with an opening and is assembled on the shell in a non-direct-contact mode, and the opening corresponds to the assembly port; the light valveis arranged on the assembly part and comprises a base and an imaging element, and the imaging element comprises an imaging surface; the base is supported against the assembly part, and the imaging surface of the imaging element is located at the opening of the assembly; a cavity is defined by the shell, the assembly part and the light valve; the first heat exchange assembly is arranged on the assembly part and comprises at least one first heat conduction piece and first heat dissipation fins; the first heat dissipation fins are located outside the shell; the first heat conduction piece extendsout of the shell from the assembly part and is connected with the first heat dissipation fins. The heat dissipation effect of the front end of the light valve can be improved.

Description

technical field [0001] The invention relates to an optical device and a projector, and in particular to an optical machine module and a projector with the 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 ...

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
