According to the requirement to airborne indicator performance in national military standard " GJB5435 airborne AMLCD luminosity and colour measurement method " and " the airborne AMLCD general specification of GJB5187 ", the display of fighter plane passenger cabin needs to carry out the resolving power test under full daylighting environment under 107640lx direct projection ambient light illumination, realize the simulation of background light radiation condition in high-altitude sunlight direct irradiation condition gets off the plane passenger cabin, below shadow shield, display also needs to carry out resolving power test under the direct projection ambient light illumination of 21500lx.Therefore need to use high brightness direct projection light source during resolving power test under to the full daylighting environment of airborne indicator and the output area of the illuminance between 21500lx to 107640lx is provided.The output illumination of conventional illumination sources is usually at below 1000lx, and the illumination that can not reach direct sunlight rank exports, and therefore needs us to design a kind of new light source, realizes the simulation of the illumination conditions to the full daylighting environment of airborne indicator.
Utility model content
Cannot reach the problem of the measuring illuminance numerical value of airborne indicator for existing lighting source, the utility model provides a kind of adjustable type super brightness direct projection light source.
The utility model adopts following technical scheme:
A kind of adjustable type super brightness direct projection light source, comprise light shell outer cover, direct output light source mechanism and adjustable aperture diaphragm are housed in described light shell outer cover successively, the outside front side of light shell outer cover is equipped with optical alignment system and filtering mechanism successively, and the center of direct output light source mechanism, adjustable aperture diaphragm, optical alignment system and filtering mechanism point-blank.
Preferably, described direct output light source mechanism comprises throwing face mirror, metal halide lamp and the convergent lens of arranging successively, throws the center of face mirror, metal halide lamp and convergent lens point-blank.
Preferably, described filtering mechanism comprises the colour temperature of arranging successively and regulates optical filter and cutoff filter, and colour temperature regulates the center of optical filter and cutoff filter point-blank.
Preferably, the roof of described light shell outer cover and sidewall all offer hole, the hole place of the roof of light shell outer cover is provided with fan.
The beneficial effect that the utility model has is:
The direct projection light source that the utility model provides, the direct output light source mechanism set gradually in light shell outer cover and adjustable aperture diaphragm, the outside front side of light shell outer cover is equipped with optical alignment system and filtering mechanism successively, adjustable aperture diaphragm can by regulating the setting of aperture size realization to emergent light clear aperature, the illuminance that light source is exported can reach between 21500lx to 107640lx, meet the definition requirement that airborne indicator is measured, the background radiation light source that this direct projection light source can use as resolving power test under the full daylight condition of airborne indicator.
Colour temperature in filtering mechanism regulates optical filter to ensure, and the colour temperature exporting light is between 4500k to 6000k, cutoff filter, be used for absorbing the heat radiation light of the infrared band that irradiated object is heated up, avoid and the characteristics of luminescence of airborne AMLCD itself is had an impact, make output light source more be applicable to testing the photometric parameter of airborne indicator.In addition, the hole place of light shell outer cover roof is provided with fan, and fan carries out convective cooling to lamp box inside, ensure that light source internal temperature can not be too high.The output facula of the direct projection light source that the utility model provides has higher uniformity and stability, in the Test Application of reality, achieve good simulate effect.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is specifically described:
Composition graphs 1 and Fig. 2, a kind of adjustable type super brightness direct projection light source, comprise light shell outer cover 9, in described light shell outer cover 9, direct output light source mechanism and adjustable aperture diaphragm 4 are housed successively, the outside front side of light shell outer cover 9 is equipped with optical alignment system 5 and filtering mechanism successively, and the center of direct output light source mechanism, adjustable aperture diaphragm 4, optical alignment system 5 and filtering mechanism point-blank.
Wherein, direct output light source mechanism comprises throwing face mirror 1, metal halide lamp 2 and the convergent lens 3 of arranging successively, throws the center of face mirror 1, metal halide lamp 2 and convergent lens 3 point-blank.
Metal halide 2 is placed on the focus place of throwing face mirror 1, the light that metal halide lamp 2 sends dorsad becomes forward directional light through throwing after face mirror 1 reflects, the light of this forward directional light and metal halide lamp 2 forward direction transmission together through convergent lens 3, thus improves the energy density of emergent ray greatly.
The emergent ray of convergent lens 3 is successively through adjustable aperture diaphragm 4 and optical alignment system 5, and adjustable aperture diaphragm 4 by regulating the setting of aperture size realization to emergent light clear aperature, thus can realize the adjustment of light illumination; After light collimates by optical alignment system 5, ensure the quality of outgoing beam.
