Dustproof, noise-reduction and heat-dissipation device of laser television

Abstract

The invention discloses a dustproof, noise-reduction and heat-dissipation device of a laser television. The dustproof, noise-reduction and heat-dissipation device of the laser television is provided with a heat-dissipation structure matched with an optical engine, wherein the optical engine is a laser optical engine; a red semiconductor laser, a green semiconductor laser and a blue semiconductor laser are adopted as light sources of the optical engine; the heat-dissipation structure is composed of heat-dissipation fans and an air duct; the air duct has two air inlets and four air outlets, wherein the four air outlets respectively are a red light air outlet, a blue light air outlet, a green light air outlet and a polarizer air outlet, and the air inlets are provided with dust-proof nets; and the heat-dissipation fans are arranged in the air duct at a lower portion of the optical engine. With the dustproof, noise-reduction and heat-dissipation device of the laser television adopted, a large quantity of heat can be taken away, and heat dissipation ability can be improved, and dust entering the laser television can be reduced, and noise of a whole machine can be reduced.

Description

technical field [0001] The invention belongs to the technical field of laser televisions, and in particular relates to a dust-proof, noise-reduced and heat-dissipating device for laser televisions. Background technique [0002] At present, there is a common problem in large-screen TVs such as rear-projection TVs, plasma TVs, and flat-screen TVs, that is, the problems of dustproof, noise reduction and heat dissipation of TVs. The optical path system is the key to ensure the image quality of the whole machine. Its rationality determines whether the structure of the whole machine is reasonable and whether the whole machine can be used for a long time without the optical path being polluted and the image quality not degrading. Dust has a very serious impact on the laser TV, because dust will not only affect the heat dissipation effect of the laser TV, but also if there is dust around the laser TV lens, it will affect the quality of the laser TV picture, and in serious cases, it ...
