Problems solved by technology

[0002] In the existing LED lighting and display system, the light efficiency loss is very large, and the diffusion film or diffusion plate used will generally reduce the light efficiency of the LED light source by about 20%.
Taking the LED panel lights currently on the market as an example, the general luminous efficacy is 80~100 lm / W. To achieve higher brightness, it is necessary to increase the power of the light source or increase the number of lamp beads, which is not economical nor energy-saving and environmentally friendly.

Abstract

The invention discloses a microprism structure and an application thereof. A microprism structure is an array composed of lying pyramid structures, the angle between the inclined surface of the microprism structure and the bottom surface of the microprism structure is 30 to 90 degrees, and the vertical depth of a single pyramid structure is 20 to 30 [mu]m, and the top spacing of every two adjacentpyramid structures is 50-80 [mu]m. According to the microprism structure, the light efficiency utilization rate can be increased, and light diffusion and uniformization effects are good.

Description

technical field [0001] The invention relates to a microprism structure and its application. Background technique [0002] The light efficiency loss in the existing LED lighting and display system is very large, and the diffusion film or diffusion plate used generally reduces the light efficiency of the LED light source by about 20%. Taking the LED panel lights currently on the market as an example, the general luminous efficacy is 80~100 lm / W. To achieve higher brightness, it is necessary to increase the power of the light source or increase the number of lamp beads, which is not economical nor energy-saving and environmentally friendly. Contents of the invention [0003] The purpose of the present invention is to provide a micro-prism structure and its application, aiming at improving light utilization rate and having good diffusion and homogenization effect at the same time. [0004] In order to achieve the above object, the technical solution of the present invention i...
