Abstract
The invention discloses a light source diffusion plate, comprising two tooth-shaped plates (1) with opposite tooth faces; one face of each tooth-shaped plate (1) is a plane while the other face is provided with a plurality of tooth-shaped bulges (2); the tooth-shaped bulges (2) have thick root parts and thin head parts; the tooth-shaped bulges (2) of one tooth-shaped plate (1) point to bulge gaps (3) of the other tooth-shaped plate (1). Light rays diffused by the light source diffusion plate are soft and uniform.
Description
Technical field
The present invention relates to a kind of light source diffusion plate.
Background technology
In liquid crystal display and other various light sources illumination use field, usually wish to obtain the light high conformity, evenly soft light.Light source diffusion plate is arranged on the light source outside usually, for conduction and scattered beam, make diffuser plate after the light rule unified, thereby obtain uniform light.
In the liquid crystal display industry, diffuser plate commonly used is the two-layer composite through being polymerized by transparent substrate and one deck diffusion barrier, this diffuser plate, the surface diffusion film is compounded on transparency carrier with coating method, the surface of the diffusion barrier applied and the basic depth of parallelism are not ideal enough, and diffusion effect is poor.Cause the distribution of light inequality, and easily jaundice after the long-term use of composite membrane.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the purpose of this invention is to provide a kind of light source diffusion plate, obtain evenly soft diffusing light.
Technical scheme of the present invention is such: a kind of light source diffusion plate, it is characterized in that: comprise two castellated plates that the flank of tooth is relative, described castellated plates is simultaneously plane, another side is provided with some dentations, described dentation is the thick and thin projection of head of root, and the dentation of described castellated plates points to the projection gap of another piece castellated plates.
Preferably, described castellated plates spacing is less than 5cm, and described dentation height is less than 4cm.
The advantage of technical scheme provided by the present invention is, illuminating source is luminous in light source diffusion plate one side, light can form refraction and reflection repeatedly after by light source diffusion plate, while by a castellated plates, conducting to another piece castellated plates, same produce repeatedly refraction and reflection, it is soft and even that the light that makes finally to send from the opposite side of light source diffusion plate is thought.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with embodiment, the invention will be further described, but not as a limitation of the invention.
Refer to Fig. 1, light source diffusion plate, comprise two castellated plates 1 that the flank of tooth is relative, castellated plates 1 one side is plane, another side is provided with some dentations 2, and dentation 2 is the thick thin projection of head of root, and the dentation 2 of castellated plates 1 points to the projection gap 3 of another piece castellated plates 1.This light source diffusion plate is made with the high light transmittance ratio glass base material, and castellated plates 1 spacing is less than 5cm, and dentation 2 highly is less than 4cm and obtains good diffusion effect.
Claims (2)
1. a light source diffusion plate, it is characterized in that: comprise two castellated plates (1) that the flank of tooth is relative, described castellated plates (1) one side is plane, another side is provided with some dentations (2), described dentation (2) is the thick thin projection of head of root, and the dentation (2) of described castellated plates (1) points to the projection gap (3) of another piece castellated plates (1).
2. light source diffusion plate according to claim 1, it is characterized in that: described castellated plates (1) spacing is less than 5cm, and described dentation (2) highly is less than 4cm.
