Description
Technical field
The present invention relates to a kind of projecting camera light bulb fixed sturcture, relate in particular to and a kind ofly avoid bulb reflex housing printing opacity to form parasitic light and affect the projecting camera light bulb fixed sturcture of optical property.
Background technology
Light engine in the structure of projector's product (Optical Engine) is an important key component, and it includes a light source lamp and an optical module.Described light source lamp is to be modular structure, there is the composition members such as bulb, reflex housing, lamp socket and Lamp cup, described bulb is arranged in described reflex housing, assembles by described reflex housing the high light that described bulb sends, and irradiates towards described optical module to produce a projecting beam.Described bulb mainly uses as tungsten halogen lamp, metal halide lamp, ultrahigh pressure mercury lamp or xenon lamp etc., and the denominator that these bulbs have is exactly that luminous intensity is high and bright.Therefore, the high light of described bulb, when by described reflex housing optically focused, all can have part high light to see through described reflex housing and form parasitic light.Described parasitic light will carry out scattering by the ventilating opening of projector housing, thereby image projection screen and projection environment are impacted.Be generally the problem that light source bulb parasitic light leaks outside that solves, conventionally can between ventilation fan mouth and bulb reflex housing, light barrier be set, covered described parasitic light by described light barrier.But described light barrier is plates and arranges before ventilating opening, not only the weak effect of shading affects again the cooling performance of projector simultaneously.How to promote shaded effect and avoid affecting cooling performance, should be studied and be improved again.
Summary of the invention
In view of this, be necessary to provide a kind of shaded effect well not affect again the projecting camera light bulb fixed sturcture of heat radiation running.
The invention provides a kind of projecting camera light bulb fixed sturcture, it comprises a lamp module, first housing and second housing, described lamp module comprises a lamp socket and a reflex housing, in described reflex housing, there is a bulb setting, described reflex housing is arranged on described lamp socket, described the first housing and described the second housing snapping form a shell, and described shell is arranged at the outer periphery of described reflex housing and is fixed on described lamp socket.
Compare prior art, projecting camera light bulb fixed sturcture of the present invention, the described shell forming by described the first housing and described the second shell combination, described shell is arranged to the outer periphery of described reflex housing, can hide completely and see through the parasitic light that described reflex housing is dispersed, can avoid stopping the radiating airflow of projector, improve the quality of projector simultaneously.
