Abstract
The utility model discloses a little prism structure light guide plate, it includes the light guide plate, the front of light guide plate is glossy mirror surface, and is equipped with little prism structure on the right reverse side of light guide plate front picture, little prism structure is two sets of above prism groups of parallel arrangement each other, every group the prism group includes the mutual dislocation set of the hemispherical prism body of the hemispherical prism body more than two that the interval set up, adjacent two sets of prism groups. The utility model discloses a preparation simple process of light guide plate, production efficiency is high, and is with low costs, little prism structure and light guide plate integrated into one piece need not the secondary photoprocess, and the plain noodles of advancing that only need cut, polish light can. The utility model discloses a light efficiency of light guide plate is high, and the homogeneity is good, is applicable to comprehensive application of the lamps and lanterns and the lamp house of various structures.
Description
Technical field
This utility model relates to a kind of micro-prism structure light guide plate.
Background technology
The minute surface light guide plate that acrylic makes, after light enters, owing to not having the medium can in light guide plate internal reflection or refraction by light in plate or on border, and owing to angle of incidence is excessive, light is only capable of in light guide plate internal reflection thus tabula rasa cannot be launched, produce total reflection phenomenon, light guide plate is a kind of product that point/line source is changed into area source, be the PMMA/PC utilizing optical grade it is base material, then stamp conduit point with the hitech materials with high emissivity and not extinction at the acryl plates bottom surface screen printing technology of optical grade or make light alignment different angles spread by light guide plate surface micro structure, and then destroy total reflection, light is penetrated from light guide plate front, via different density, the optics site of size form and microstructure design, light source is made to be uniformly distributed on light guide plate.
Light guide plate processing technology in the market is varied, has silk-screen, ink-jet, laser dotting, double-side micro structure and adds the modes such as astigmatism nanoparticle in light guide plate, but the light guide plate of these different processing modes is all there is each inevitably defect.Production environment is required height by silk-screen, and printing-ink environmental pollution is serious；Laser dotting or ink-jet then mass productivity is low, cost is high；Double-side micro structure, the light efficiency adding astigmatism nanoparticle are low, lack of homogeneity.
Summary of the invention
The purpose of this utility model is in that to overcome the deficiencies in the prior art, it is provided that a kind of processing technology is simple, and production efficiency is high, low cost, and light efficiency is high, the micro-prism structure light guide plate that uniformity is good.
The technical solution adopted in the utility model is:
A kind of micro-prism structure light guide plate, it includes light guide plate, the front of described light guide plate is smooth minute surface, it is provided with micro-prism structure with the reverse side of light guide plate vis-a-vis, described micro-prism structure is prism group arranged in parallel more than two, often organizing described prism group and include spaced plural hemispherical prism, the hemispherical prism mutual dislocation of two adjacent groups prism group is arranged.
The front of described light guide plate and reverse side be arranged in parallel.
Described micro-prism structure is one-body molded with light guide plate.
Described light guide plate is made up of the transparent plastic of polycarbonate or poly-methacrylate fat.
This utility model adopts above technical scheme, by arranging micro-prism structure on the reverse side of light guide plate, after making light enter light guide plate, after the transmitting of micro-prism structure and refraction, change the direction of propagation of light, final light is from the front injection with smooth mirror surface of light guide plate, by the arranged distribution to micro-prism structure, the injection of the uniform light under the transmitting and refraction action of micro-prism structure.The processing technology of light guide plate of the present utility model is simple, and production efficiency is high, and cost is low；Micro-prism structure and light guide plate are one-body molded, it is not necessary to secondary optics is processed, only need to cut, polish light enter bright finish.The light efficiency of light guide plate of the present utility model is high, and uniformity is good, it is adaptable to the light fixture of various structures and the overall application of lamp box.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, this utility model is described in further details；
The structural representation of a kind of micro-prism structure light guide plate of Fig. 1 this utility model；
The reverse side schematic diagram of a kind of micro-prism structure light guide plate of Fig. 2 this utility model.
Detailed description of the invention
As shown in Figure 1 or 2, this utility model includes light guide plate 1, the front of described light guide plate is smooth minute surface, it is provided with micro-prism structure 2 with the reverse side of light guide plate vis-a-vis, described micro-prism structure 2 is prism group arranged in parallel more than two, often organizing described prism group and include spaced plural hemispherical prism 21, hemispherical prism 21 mutual dislocation of two adjacent groups prism group is arranged.
The front of described light guide plate 1 and reverse side be arranged in parallel.
Described micro-prism structure 2 is one-body molded with light guide plate 1.
Described light guide plate 1 is made up of the transparent plastic of polycarbonate or poly-methacrylate fat.
This utility model adopts above technical scheme, by arranging micro-prism structure on the reverse side of light guide plate, after making light enter light guide plate, after the transmitting of micro-prism structure and refraction, change the direction of propagation of light, final light is from the front injection with smooth mirror surface of light guide plate, by the arranged distribution to micro-prism structure, the injection of the uniform light under the transmitting and refraction action of micro-prism structure.
In sum, the processing technology of light guide plate of the present utility model is simple, and production efficiency is high, and cost is low；Micro-prism structure and light guide plate are one-body molded, it is not necessary to secondary optics is processed, only need to cut, polish light enter bright finish.The light efficiency of light guide plate of the present utility model is high, and uniformity is good, it is adaptable to the light fixture of various structures and the overall application of lamp box.
