[detailed description of the invention]
Feature of present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, in order to the understanding of technical staff of the same trade:
As Figure 1-5, a kind of anti-dazzle tabula rasa for being arranged on LED projection lamp group front end, include the plate body 1 that LED projection lamp group is played the effect of being in the light, described plate body 1 is provided with mean for several through holes 2 that LED projection lamp group is outwards luminous, the plate body 1 at described through hole 2 place is provided with outward direction and is extended with cylinder 3, being provided with the some pieces of demarcation strips 31 for cylinder 3 is divided into multiple passage in described cylinder 3, every piece of demarcation strip 31 is all perpendicular to described plate body 1.
nullAs mentioned above，During use，Because the LED projection lamp group of its rear end is acted the effect of being in the light by plate body 1，Therefore，LED projection lamp group is outwards luminous only by through hole 2，Namely the effect by the outwards luminescence of other regions outside through hole 2 of the LED projection lamp group is limited，Thus first time reduces the dispersion angle that LED is luminous，And，On the plate body 1 at described through hole 2 place, outward direction is extended with cylinder 3，Namely LED projection lamp group issued light also needs to by getting to the external world after cylinder 3，So，Second time reduces the dispersion angle that LED is luminous，Separately，Cylinder 3 is provided with the polylith demarcation strip 31 for cylinder 3 is divided into several passages，Every piece of demarcation strip 31 is all perpendicular to described plate body 1，So，The light entered in a certain passage will not be dissipated in other passages before injection cylinder 3，Namely third time reduces the dispersion angle that LED is luminous.As mentioned above, 3 restrictions are passed through during the light injection cylinder 3 that LED projection lamp group sends, the light dispersion angle making injection reduces, well it is pointed into specifying region, the anti-dazzle tabula rasa outer surface of LED projection lamp group is not mainly can only see the distant place personnel specifying region, without being immediately seen dazzling LED projection lamp group, this case anti-dazzle effect is very prominent, and practicality is good.
As it has been described above, described cylinder 3 stretches out outside plate body 1, be conducive to, while the dispersion angle suppressing LED projection lamp group luminous further, reducing the thickness of plate body 1；Described demarcation strip 31 is perpendicular to described plate body 1, is conducive to while reducing the dispersion angle that LED projection lamp group is luminous further, and the luminescence not hindering LED projection lamp group is pointed into specifying region.
As mentioned above, when being embodied as, described demarcation strip 31 is 4 pieces, its two horizontal stroke two erects and is arranged in cylinder 3, it is staggered to form " well " character form structure, described cylinder 3 is divided into 9 passages, so, while being conducive to LED projection lamp group to be pointed into specifying region, it is not immediately seen, at the not The book of Changes cylinder 3 of personnel nearby specifying region, the LED projection lamp group that rear end is dazzling.
As it has been described above, when being embodied as, described through hole 2 inwall is provided with draw-in groove 21, and described cylinder 3 outer wall is provided with the fixture block 32 coordinating clamping with described draw-in groove 21.So, it is simple to cylinder 3 is fixed in through hole 2, it is simple to actual manufacture and assembling.
As it has been described above, when being embodied as, on described through hole 2 inwall, draw-in groove 21 is two, its circumferentially spaced apart 180 degree, the fixture block 32 on described cylinder 3 outer wall is also two, its also circumferentially spaced apart 180 degree.
As it has been described above, when being embodied as, described plate body 1 is additionally provided with and is easily installed fixing screw hole 4.
As it has been described above, when being embodied as, described plate body 1 is made by light-proof material or semi transparent material, or made by after light transmissive material is smeared light tight/semi-transparent material, so, it is simple to actual enforcement, it is simple to LED projection lamp group is acted the effect of being in the light.
As it has been described above, as it is shown on figure 3, when being embodied as, described cylinder 3 stretches out the height thickness more than or equal to described plate body 1 on described plate body 1 surface, so, under the depth information not increasing plate body 1, be conducive to the dispersion angle well suppressing LED projection lamp group luminous.
As it has been described above, when being embodied as, described plate body 1 is oblong-shaped or square shape or U-board shape.
As it has been described above, this case protection is a kind of anti-dazzle tabula rasa for being arranged on LED projection lamp group front end, all technical schemes same or like with this case structure all should be shown as in the protection domain falling into this case.
