Abstract
The utility model discloses a total internal reflection prism line light diffusion plate. A surface of the total internal reflection prism line light diffusion plate is a plane, and the other surface is provided with a concave dihexagonal prism line array. Light diffusion of the total internal reflection prism line light diffusion plate is good, lighting effect is high, and cost is low.
Description
Technical field
The utility model relates to a kind of light diffusing sheet, particularly a kind of total internal reflection prism line light diffusing sheet.
Background technology
Along with socioeconomic development, increasing light fixture, advertising lamp box, display screen adopt the point/line source of LED or other high brightness, usually adopt light diffusing sheet that light source is diffused as the uniform area source of brightness, the effect of weighing the light diffusion is mist degree and transmittance, and both are more high better.Traditional light diffusing sheet is to add astigmatic masterbatch in clear sheet, by astigmatic agent scattering of light is reached the light diffusion effect, owing to exist astigmatic agent to the occlusion effect of light, more its transmittances of the astigmatic agent that the light diffusing sheet that mist degree is higher adds are lower.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of total internal reflection prism line light diffusing sheet, and the light diffusion effect is good, and light efficiency is high, and cost is low.
The technical scheme that the utility model technical solution problem adopts is: a kind of total internal reflection prism line light diffusing sheet, and it simultaneously is the plane, another side is provided with recessed six prism pattern arrays.
The angle on the relative inclined-plane of six prisms need meet the total reflection condition of incident light in the utility model, the arranging of recessed six prism pattern arrays, the size of prism and the angle of minute surface can be regulated as required, to obtain the optimum efficiency of various light diffusions, the less smooth diffusion effect of prism is better, to obtain the optimum efficiency of various light diffusions, can make thinner high efficiency, low cost light diffusing sheet or sheet simultaneously.
The beneficial effects of the utility model are: plate body simultaneously is provided with recessed six prism pattern arrays, to put or line source is diffused as the uniform area source of brightness by the catadioptric of prism, the light diffusion effect is good, and light efficiency is high, its brightness is much higher than the normal optical diffuser plate under same light source, and cost is low.
