Uniform light structure and uniform light system

Abstract

The invention discloses a dodging structure and a dodging system. The dodging structure comprises a dodging substrate, wherein the dodging substrate comprises a substrate body, a first pattern structure arranged at any surface of the substrate body, and a reflection layer arranged at one side of any surface of the dodging substrate, wherein the first pattern structure comprises multiple micro structures used for dodging incident light beams irradiated on the surface, and a reflection face of the reflection layer faces towards the dodging substrate. The any surface of the dodging substrate is provided with the reflection layer, when the incident light beam irradiates one side surface of the dodging substrate having no reflection layer, part of the light is reflected by the surface, the part light flows into the surface of the reflection layer and then is reflected out of the dodging substrate, and the light beams is the light beams after secondary reflection after being dodged by the dodging structure. Through the structure, the incident Gauss distribution light beams are shaped into flat-topped distribution light beams, the light beam diffusion angle is small, light beam collection is facilitated, and requirements of small volume and light mass for a display system are satisfied.

Description

technical field [0001] The invention relates to the technical field of uniform light, and more specifically, to a uniform light structure and a uniform light system. Background technique [0002] In the prior art, the uniform light of the light is mainly realized through the compound eye. like figure 1 As shown, it is a schematic diagram of an existing fly-eye uniform light, wherein, when the incident light passes through the first group of fly-eye lenses 100 and the second group of fly-eye lenses 200, the first group of fly-eye lenses 100 divides the incident light beam into multiple sub-beams, and the second group of lenses 200 recombines and superimposes the multiple sub-beams, so as to achieve uniform light effect. When the curvature of the microlens of the fly-eye lens is low, the diffused angle of the light beam after homogenization is large, and it is necessary to use a large-area collection lens or place the collection lens far away from the fly-eye lens to collect...

Problems solved by technology

When the curvature of the microlens of the fly-eye lens is low, the diffused angle of the light beam after homogenization is large, and it is necessary to use a large-area collection lens or place the collection lens far away from the fly-eye lens to collect the light beam after homogenization. This structure is difficult to satisfy Display system requirements for small size and light weight

In order to solve this problem, the curvature of the fly eye lens needs to be processed relatively large, but it is difficult to manufacture a fly eye lens with a large curvature
