Compared with prior art, the beneficial effects of the utility model comprise: by arranging luminous intensity distribution reflective mirror, and the light-distribution lens being used for reflecting the collimated light beam that light distribution reflecting mirror reflects is set between luminous intensity distribution reflective mirror and loophole, the light that luminous component sends is reflected, and penetrates in loophole after described light-distribution lens refraction.The light of luminous component is dispersed in preset path, thus by the Angle ambiguity of the light of injection in more among a small circle, light is avoided too to disperse, and disguised bad problem, front black-out lamp described in the utility model, it is hidden functional, and structure is simple simultaneously, practical.
Accompanying drawing explanation
Fig. 1 is the perspective cross section anatomical connectivity schematic diagram of front black-out lamp of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
In order to solve the technical problem of black-out lamp air defense weak effect in prior art, embodiment of the present utility model provides a kind of front black-out lamp, as shown in Figure 1, comprise inner hollow and the housing 1 of one end open, and the lid 2 covered in described housing 1 openend, the inwall of described housing 1 is provided with a luminous component 3, the top of described luminous component 3 is provided with a luminous intensity distribution reflective mirror 4, the horizontal level of the relatively described luminous intensity distribution reflective mirror 4 of described lid 2 is provided with a loophole 21, a light-distribution lens 5 is provided with between described loophole 21 and described luminous intensity distribution reflective mirror 4, concrete, described light-distribution lens is vertically arranged on inside described loophole, the light of described luminous component 3 reflexes to light-distribution lens 5 through luminous intensity distribution reflective mirror 4, and penetrate in loophole 21 after described light-distribution lens 5 reflects.Concrete, the luminous component 3 adopted in the utility model embodiment is high-power bulb.
Concrete, embodiment of the present utility model is by arranging luminous intensity distribution reflective mirror 4, and the light-distribution lens 5 being used for reflecting the collimated light beam that light distribution reflecting mirror 4 reflects is set between luminous intensity distribution reflective mirror 4 and loophole 21, the light that luminous component 3 sends is reflected, and penetrates in loophole 21 after described light-distribution lens 5 reflects.The light of luminous component 3 is dispersed in preset path, thus by the Angle ambiguity of the light of injection in more among a small circle, avoids light too to disperse, and disguised bad problem.
Further, described lid 2 extends a plane 22 in described housing 1, the horizontal level of described plane 22 is higher than the horizontal level of described luminous component 3, but lower than the horizontal level of described luminous intensity distribution reflective mirror 4, the logical optical channel of luminous component 1 is formed between described plane 22 and the inwall of described housing 1, the light that sends of restriction luminous component 1 from logical optical channel direct projection on luminous intensity distribution reflective mirror 4, avoid the scattered beam of described luminous component 3 directly through described light-distribution lens 5 on the one hand, and cause the angle of light guide too to disperse from described loophole 21 injection, be unfavorable for illumination, set the opticpath of luminous component on the other hand, the angle of bright dipping is controlled further in more among a small circle.
Further, the minute surface axis of described luminous intensity distribution reflective mirror 4 and the axis parallel of described loophole 21 arrange and are located at same level, the minute surface of this horizontal plane and described luminous intensity distribution reflective mirror 4 forms one and reflects angle, ensure that the light of described luminous component 3 can from described loophole 21 straight line injection after luminous intensity distribution reflective mirror 4 reflects, and ensure more light is penetrated from loophole 21, the brightness of this front black-out lamp is improved.The shape of described loophole is horizontally disposed rectangular strip.Concrete, described reflection angle is 15 °-75 °, and preferably 45 °, the light that concrete condition luminous component 3 sends is determined.
Further, heat can be produced due to during described luminous component work, these heat accumulations easily cause temperature in housing too high in described housing 1, the service life of shortening equipment, therefore, arrange an air-vent 11 at the closing end of described housing 1, described air-vent 11 protrudes laterally, is also provided with one for covering the ventilating cover 12 of described air-vent 11 outside described air-vent 11.When temperature is too high in housing 1, pull up ventilating cover 12, make the carrying out ventilation cooling in housing 1, thus extend the service life of whole equipment.
Further, described lid 2 and described housing 1, for being connected together, being convenient to dismounting and keeping in repair this front black-out lamp.
Front black-out lamp described in the utility model, by arranging luminous intensity distribution reflective mirror, and the light-distribution lens being used for reflecting the collimated light beam that light distribution reflecting mirror reflects is set between luminous intensity distribution reflective mirror and loophole, the light that luminous component sends is reflected, and penetrates in loophole after described light-distribution lens refraction.The light of luminous component is dispersed in preset path, thus by the Angle ambiguity of the light of injection in more among a small circle, light is avoided too to disperse, and disguised bad problem, front black-out lamp described in the utility model, it is hidden functional, and structure is simple simultaneously, practical.
The above detailed description of the invention of the present utility model, does not form the restriction to the utility model protection domain.Any various other made according to technical conceive of the present utility model change and distortion accordingly, all should be included in the protection domain of the utility model claim.
