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.
Below in conjunction with specific embodiment, specific implementation of the present utility model is described in detail:
Please refer to Fig. 1 ~ 3, the utility model embodiment provides a kind of optical texture plate, for in LED light device, to high angle scattered light, there is receipts light action, this optical texture plate comprises flat transparent body 1 and multiple convex light focusing unit 2 of evenly arrangement at least one surface of body 1, the surface of convex light focusing unit 2 is mirror surface structure, body 1 and convex light focusing unit 2 one-body molded, multiple convex light focusing unit 2 lines up multiple row, the convex light focusing unit 2 of adjacent column is interspersed, and makes multiple convex light focusing unit 2 entirety in cellular.
This optical texture plate adopts high light transmissive material fluoropolymer resin class plastic production, specifically can adopt PC (Merlon, Polycarbonate), PS (polystyrene, Polystyrene), PMMA (polymethyl methacrylate, or MS ((methyl methacrylate PolymethylMethacrylate), and (styrene Methylmethacrylate), Styrene) synthetic copolymer) material made by injection moulding or extrude, wherein undoped other light diffusing particles, this optical texture plate has higher transparency and good mechanical strength.
Above-mentioned convex light focusing unit 2 can be formed at a surface 11 of body 1, and another surface 12 is mirror plane or frosted plane.Also can all form above-mentioned convex light focusing unit 2 on two surfaces of body 1, the structure of the convex light focusing unit 2 on this two surface and quantity and arrangement mode preferably identical.
