Abstract
The invention discloses a liquid crystal on silicon (LCOS) projector, which comprises an engine, a cover body for sealing off the engine, and a radiator, wherein the radiator is connected with the engine and used for transmitting heats produced by the engine; the engine is accommodated in a closed cover body by the LCOS projector, and the heats produced by the engine are transmitted to the outside by the radiator so as to reduce the temperature of the engine, thereby achieving a good cooling effect; meanwhile, external dusts or dirt can not enter the inside of a closed case body, thus being capable of achieving the effects of dust prevention and temperature reduction, and effectively avoiding the pollution of dusts and dirt on the engine.
Description
[technical field]
The present invention relates to a kind of image documentation equipment, especially a kind of LCOS projector.
[background technology]
LCOS shadow casting technique claims that again (Liquid Crystal on Silicon LCOS), is a kind of emerging technology in conjunction with semiconductor technology and LCD (LCD) for liquid crystal on silicon, silicon wafer optical tech.The core devices of LCOS projector is exactly the LCOS chip.The basic structure of this chip is to cover the liquid crystal molecule coating layer on the back plane circuitry of CMOS.
In traditional LCOS projector, traditional mode is exposed outside this imaging system, if dust, oil smoke and dust etc. occur in optical element wherein or the image-forming component, can cause the pollution of parts, thereby influence the contrast of LCOS projector.And traditional method is the pollution of dust in air etc. when being used for stopping the imaging system cooling by making of Air Filter, dustproof sponge, but this traditional dust-control method has caused the imaging system surface dirt to be piled up, cause heat accumulation, produce hot deterioration, seriously reduced the image quality of projected image.
[summary of the invention]
Based on this, be necessary to provide a kind of LCOS projector that can either prevent dust and can lower the temperature.
A kind of LCOS projector comprises engine, seals the lid and the heating radiator of described engine, and described heating radiator is connected with engine and conducts the heat that described engine produces.
Preferably, described lid comprises top shell and drain pan, and the front of described drain pan is provided with breach.
Preferably, the bottom surface of described drain pan is provided with the heat interchange hole, and described heat interchange hole and described heating radiator are suitable.
Preferably, the edge of described heating radiator is provided with the heat absorbing sheet vertical with heating radiator, forms host cavity.
Preferably, the bottom of described heating radiator is the hot fin of barrier shape, and described hot fin is arranged on the outside of lid.
Preferably, described engine comprises prism assemblies, the prism drain pan of fixed prism assembly and the camera lens that connects prism assemblies.
Preferably, an end of described camera lens is provided with stator, and four jiaos of described stator are provided with screw, and screw is fastened to described prism drain pan by described screw.
Preferably, described heat absorbing sheet and described prism assemblies are close to setting.
Above-mentioned LCOS projector is housed in engine in the lid of sealing; by heating radiator the heat that engine produced is conducted to the external world; make the temperature of engine reduce; reach good cooling effect; also make extraneous dust or dust can't enter the inside of enclosed box body; reach the effect that promptly can prevent dust and can reduce temperature, avoided the pollution of dust, dust effectively engine.
Drain pan at lid is provided with the heat interchange hole that exchanges with radiator heat, designs cleverly by this, timely the heat of engine is conducted to the external world.
Three edges of heating radiator are provided with the heat absorbing sheet that and direction vertical with heating radiator extended, and partly accommodate optical module, can increase the contact area with optical module, improve radiating efficiency.
Hot fin is arranged on the outside of lid, utilizes the heat interchange hole that heat is in time passed to the external world cleverly, has also saved material simultaneously.
The prism drain pan is set in the engine, connects prism assemblies and camera lens by this prism drain pan, make projector in carrying, move etc. in the process, this camera lens can not be offset, and has guaranteed that this projector has the projection imaging effect of high-quality when in use.

[embodiment]
Shown in Fig. 1～3, LCOS projector comprises: engine 200, seal the lid 100 and the heating radiator 300 of described engine 200, and described heating radiator 300 is connected with engine 200 and conducts the heat that described engine 200 is produced.
Elaborate the application process of LCOS projector below in conjunction with a specific embodiment, among this embodiment, during LCOS projector work, the engine 200 of lid 100 inside produces a large amount of heat, and especially prism assemblies 210.Prism assemblies 210 is fitted with heating radiator 300, to carry out heat interchange.Heating radiator 300 carries out heat interchange by heat interchange hole 122 and outside, and the heat release that prism assemblies 210 is produced arrives lid 100 outsides.Particularly, the hot fin 310 of heating radiator 300 is carried the pressure air,, reduce the temperature of LCOS projector work, it is worked under suitable temperature by heat being taken away with the convection current of hot fin 310 by the fan that is provided with in lid 100 outsides.
Above-mentioned LCOS projector is housed in engine in the lid of sealing; by heating radiator the heat that engine produced is conducted to the external world; make the temperature of engine reduce; reach good cooling effect; also make extraneous dust or dust can't enter the inside of enclosed box body; reach the effect that promptly can prevent dust and can reduce temperature, avoided the pollution of dust, dust effectively engine.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
