Wherein, 1, housing; 11, boss; 2, LED light source; 3, reflection shield; 31, cambered surface is reflected; 4, luminescence window; 41, part is clamped; 5, PMMA light-passing board; 6, LED power driver; 61, installed part; 62, link up with.
Detailed description of the invention
By reference to the accompanying drawings the application is described in further detail below by detailed description of the invention.
Fig. 1 shows the anti-dazzle light fixture of LED located in an embodiment of the application, the anti-dazzle light fixture of this LED comprises housing 1, the both sides, bottom surface of this housing 1 inside are respectively arranged with at least one LED light source 2, the light that the light radiation path of this LED light source 2 is provided with this LED light source 2 is launched carries out irreflexive reflection shield 3, and the reflection cambered surface 31 of this reflection shield 3 is provided with nanoscale highly reflective coatint.Namely first LED lamp bead is hidden in the both sides, bottom surface of housing 1 inside by the anti-dazzle light fixture of this LED, utilizes reflection shield 3 pairs of light to carry out diffuse reflection, to realize indirect lighting.And in order to ensure the luminous efficiency of the anti-dazzle light fixture of this LED, the reflection cambered surface 31 of reflection shield 3 coats the unrestrained anti-coating of nanometer height, and not only reflectivity can reach 97%, and effectively can also adsorb blue light.Generally, this reflection cambered surface 31 can carry out board design with computer optical software.
Further, penetrate through the bottom of irreflexive light from this housing 1, the bottom of this housing 1 offers luminescence window 4, this luminescence window 4 is provided with PMMA polymethyl methacrylate light-passing board.PMMA is macromolecule transparent material the most excellent at present, and visible light transmissivity reaches 92%, higher than the light transmittance of glass.And this PMMA light-passing board 5 can also filtering more than 70% LED ultraviolet light.
Further, this diffuser is arranged on this housing 1 inside and is positioned at the top of this LED light source 2, and the top of this diffuser is provided with LED power driver 6, and this LED power driver 6 is electrically connected with this LED light source 2 each.
To sum up, the operation principle of the anti-dazzle light fixture of this LED is as follows: when a branch of parallel incident ray that LED lamp bead is launched is mapped to nano coating surperficial, surface can light towards reflecting from all directions, so although incident ray is parallel to each other, because the normal direction of each point is inconsistent, cause reflection ray irregularly to reflect to different directions, the LED lamp bead hidden in other words be not light is directly injected working surface but nanoscale highly reflective coatint in the reflection cambered surface 31 of directive reflection shield 3 to carry out diffuse reflection work.Thus effectively avoid the generation of dazzle, in addition up to 97% reflectivity nano coating, the luminous efficiency of the anti-dazzle light fixture of this LED there is no loss.
