Abstract
Provided is a projector lamp body dustproof heat dissipation structure, comprising a lamp body and a housing on the periphery of the lamp body, and characterized in that the tail of the housing is provided with a heat dissipation fan; a heat dissipation air duct is arranged between the housing and the lamp body; one side of the housing close to a lamp holder is provided with four air outlets arranged at intervals; the heat dissipation fan, the heat dissipation air duct and the air outlets are combined to be used for heat dissipation of the lamp body; a filter screen is arranged outside the heat dissipation fan to be used for filtering dust and impurities in air. The projector lamp body dustproof heat dissipation structure has good heat dissipation effects, and can effectively prevent dust and impurities in air from penetrating into a projector, or reduce the amount of dust and impurities in air penetrating into the projector, maintain clean environment in the projector, further improve lamp body heat dissipation efficiency, and prolong the service life of the projector.
Description
Technical field
The present invention relates to projector's technical field, be specifically related to the dust-proof radiating structure of a kind of projector lamp body.
Background technology
Due to making rapid progress of science and technology, the application of projector is also all the more extensive with the life of convenient people.Common projector generally comprises housing and is arranged on photo engine, circuit board, apparatus for lighting up, light source and the corresponding cooling mechanism in housing.According to the number of camera lens used in photo engine, projector can be divided into single-lens projector and tri-lens projector again.Generally all first the white light that light source produces is isolated red, green, blue three coloured light in design, modulate three coloured light respectively by three liquid crystal light valves, three coloured light after modulation adopt diverse ways to process according to difference that is single-lens or three-lens design.In single-lens projector, be three coloured light are closed color components to be synthesized and by single lens projection imaging.In tri-lens projector, be that three coloured light are projected to imaging on same screen via different three camera lenses respectively.Wherein single-lens projector has the advantages that volume is little, be convenient for carrying, but its back focal length is longer, and the bore of camera lens requires comparatively large, and the optical module such as the camera lens used and spectroscope is very high to the requirement of quality, precision, causes cost higher.And tri-lens projector can project larger picture in comparatively short distance, picture brightness and contrast all improve a lot than single-lens projector.
Projector in the course of the work lamp body can produce a large amount of heats, the energy of lamp body bulb is except a part becomes luminous energy, major part is distributed in projector with the form of heat, and these heats, as left not in time, can have a strong impact on the normal work and use life-span of projector.Therefore in projector, be all provided with heat abstractor, generally establish the heat abstractor having plenty of projector's lamp body.The radiating principle of these heat abstractors is by arranging fan and corresponding air channel, sucks air, discharged by heat by air channel from air port when projector works from outside.But while ventilation, also the dust in air and impurity can be brought into, when applying over a long time, these dusts and impurity can stick on optical element and accessory, have a strong impact on the optical property of optical element, and affect the heat radiation of lamp body, and then to affect projector be serviceable life.
Summary of the invention
Not enough for prior art, the invention provides the dust-proof radiating structure of a kind of projector lamp body, solve the demand of projector heat radiation, there is dust-proof function simultaneously.
The technical scheme that the present invention solves the problems of the technologies described above employing is: the dust-proof radiating structure of projector's lamp body, comprise the housing of lamp body and lamp body periphery, it is characterized in that, described housing afterbody arranges cooling fan, heat dissipation wind channel is provided with between housing and lamp body, described housing is positioned at that lamp holder side is equidistant arranges 4 air outlets, and described cooling fan, heat dissipation wind channel and air outlet combine the heat radiation being used for lamp body; Described cooling fan outer setting screen pack, for the dust in filtered air and impurity.
Described cooling fan is vortex flow fan, for pumping into cooling-air.
Inside described air outlet, aerofoil fan being set, arranging outward for accelerating hot-air in heat dissipation wind channel.
Described screen pack is arranged in slot, is pluggable screen pack, after using the regular period, can extract screen pack and carry out changing or clearing up impurity, easy to use.
Described cooling fan is positioned at inside screen pack and on described air outlet and is respectively arranged with noise-abatement equipment.
The beneficial effect that the present invention has: the good heat dissipation effect of radiator structure of the present invention, effectively can stop or reduce dust in air and impurity enters in projector, keep projector's internal environment to clean, improve lamp body radiating efficiency further, extend the term of life of projector.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further.As shown in Figure 1, the dust-proof radiating structure of a kind of projector lamp body, comprise the housing 2 of lamp body 1 and lamp body periphery, it is characterized in that, described housing 2 afterbody arranges cooling fan 5, be provided with heat dissipation wind channel 3 between housing 2 and lamp body 1, described housing is positioned at that lamp holder side is equidistant arranges 4 air outlets 4, and described cooling fan 5, heat dissipation wind channel 3 and air outlet 4 combine the heat radiation being used for lamp body; Described cooling fan 5 outer setting screen pack 7, for the dust in filtered air and impurity.
Described cooling fan 5 is vortex flow fan, for pumping into cooling-air.
Inside described air outlet 4, aerofoil fan 6 being set, arranging outward for accelerating hot-air in heat dissipation wind channel.
Described screen pack 7 is arranged in slot 9, for pluggable screen pack, after using the regular period, screen pack can be extracted carry out changing or clearing up impurity, easy to use, effectively can stop or reduce dust in air and impurity enters in projector, keeping projector's internal environment to clean, further raising lamp body radiating efficiency, extends the term of life of projector.
Described cooling fan is positioned at inside screen pack 7 and on described air outlet 4 and is respectively arranged with noise-abatement equipment 8, reduces the noise that cooling air produces at cooling fan and air outlet flow at high speed, and purification working environment, improves the result of use of projector.
