Abstract
The utility model discloses a kind of photoconduction blast microstructure light diffusing sheet, it is characterized in that: the one side of described light diffusing sheet is provided with cylinder mirror array, and another side is provided with convex lens or concave mirror arrangements.The utility model is without the need to adding light diffusing agent, and light diffusion effect is good, and light efficiency is high, and cost is low.
Description
Technical field
The utility model relates to a kind of light diffusing sheet, is specifically related to a kind of photoconduction blast microstructure light diffusing sheet.
Background technology
At present, along with socioeconomic development, increasing light fixture, advertising lamp box, display screen adopt the point/line source of LED or other high brightness, simultaneously in order to reduce the thickness of light fixture, advertising lamp box, display screen, usual employing light diffusing sheet is diffused as side ray source the area source of brightness uniformity, the effect weighing light diffusion is mist degree and transmittance, and both are more high better.Traditional light diffusing sheet is in clear sheet, add astigmatism masterbatch, light diffusion effect is reached by the scattering of astigmatism agent to light, owing to there is the occlusion effect of astigmatism agent to light, the astigmatism agent that the light diffusing sheet that mist degree is higher adds its transmittances more are lower on the contrary, printed reflection horizon in the one side of light diffusing sheet again to improve brightness simultaneously, and printing not only adds cost, also have impact on the reuse of leftover pieces.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of photoconduction blast microstructure light diffusing sheet, and without the need to adding light diffusing agent, 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 photoconduction blast microstructure light diffusing sheet, is characterized in that: the one side of described light diffusing sheet is provided with cylinder mirror array, and another side is provided with convex lens or concave mirror arrangements.
Preferred as one, the height of projection of described cylinder mirror array is 70 ~ 160 μm, width 300 ~ 600 μm.
Preferred as one, the height of projection of described convex lens array is 70 ~ 160 μm; The depth of groove of described concave mirror arrangements is 70 ~ 160 μm.
In the utility model, the radian of cylinder mirror array and width and concave mirror arrangements arrangement, the size of convex lens/concavees lens and the spherical radius of convex lens/concavees lens can regulate, as required to obtain the optimum efficiency of various light diffusion.When the utility model uses, be provided with the one side of one side as light incidence of convex lens or concave mirror arrangements, the one side being provided with cylinder mirror array is then the one side of light diffusion.During as being used as LED lamp panel, will be provided with the one side of one side as LED light source incidence of convex lens or concave mirror arrangements, the one side being provided with cylinder mirror array is then the one side of light diffusion.
The beneficial effects of the utility model are: light diffusing sheet one side is provided with cylinder mirror array, another side is provided with convex lens/concave mirror arrangements, by the repeatedly catadioptric of cylinder mirror array and convex lens/concave mirror arrangements, incident ray light source refraction 90 degree is diffused as the area source of brightness uniformity, light diffusion effect is good, light efficiency is high, and under same light source, its brightness is much higher than common light diffusing sheet, and cost is low.Owing to not adding light diffusing agent, leftover pieces can direct reuse.
