Problems solved by technology

[0003] And because the light-transmitting element will be arranged between each operating element and the light source, the light-transmitting element will absorb part of the heat energy of the light when the light from the light source passes through, and the operating element will also generate waste heat when it operates. Proper heat dissipation of the optical components may affect the normal operation of the various operating components in the light valve, detracting from the reliability of the light valve

Abstract

The invention discloses a light valve heat dissipation device and a projector. In one embodiment of the invention, a heat conducting element is arranged on the light receiving surface of a light transmitting element in a light valve module, and the heat conducting element is used for conducting the heat of the light transmitting element to another heat sink different from the heat sink on the backsurface of the light valve, so that the light transmitting element is allowed to dissipate heat nearby, and the limitation during mechanism design is reduced.

Description

technical field [0001] The invention relates to a light valve cooling device and a projector, in particular to a light valve cooling device and a projector with better light valve surface temperature relieving ability. Background technique [0002] In the field of projection, a spatial light modulator is a component that can convert illumination light into image light, and a light valve is a kind of spatial light modulator. In projectors, the more common types of light valves include liquid crystal display (LCD), digital micromirror device (DMD), or liquid crystal on silicon (LCOS). In order to protect the active matrix including a plurality of actuating elements that can convert illumination light into image light, the above-mentioned various light valves usually use a light-transmitting element such as glass as a protective cover to cover the surface. [0003] And because the light-transmitting element will be arranged between each operating element and the light source, ...
