Abstract
The invention discloses a reflector plate with a light diffusion function. The reflector plate comprises a substrate, a metal plating layer for reflecting lights and a protection layer for preventing the metal plating layer from damage and oxidation, wherein the metal plating layer is plated on the surface of the substrate; the protection layer covers the metal plating layer; the contact surface between the substrate and the metal plating layer is a concave-convex rough surface; the contact surface of the metal plating layer and the protection layer is a concave-convex rough surface; when in reflection, the concave-convex rough surface generates diffuse reflection which can diffuse the lights and enable the reflected lights to be more uniform; and in addition, the reflector plate with the light diffusion function has the advantages of relatively good light reflection performance as well as long service life and simple structure, is easy to implement and can be widely applied to various products needing light reflection.
Description
Technical field
The present invention relates to a kind of material structure, specifically relate to a kind of reflector plate structure that can make the light reflection and have light diffusion function.
Background technology
The visible light that general light source sends to around disperse; When the visible light that need light source be sent is in the direction set; Can adopt the device with reflex to reflex to required direction to the light that other direction is propagated, reflector plate (reflecting plate) just has such effect.
Now, to large-sized televisor, LCDs is widely used in all kinds ofly having on the device that image shows demand from undersized MP4 and colour screen handset; Reflector plate then is widely used in LCDs; LCDs mainly comprises liquid crystal panel and module backlight, and liquid crystal panel is used to adopt light to come display image, and module backlight is used for to liquid crystal panel light being provided; Module backlight has the light source that light much is provided for liquid crystal panel; Reflector plate is used for the light that light source sends is reflexed to liquid crystal panel, and reflector plate can improve the effective rate of utilization of the light that light source sends, thereby improves the display quality of LCDs.
Traditional reflector plate generally is made up of white polymer such as macromolecule polyesters, and reflex can take place on rayed its surface, because there are some defectives in this type of reflector plate, can't well be applicable to all kinds of LCDs.So there is the dealer to work out various reflector plates; Comprising reflector plate and have reflector plate of special shape etc. with multilayer material structure; Obtain better effect with expectation; But every kind of reflector plate all has its advantage and shortcoming, so be the content that the dealer researches and develops for the improvement of reflector plate always.
A kind of reflector plate is arranged; Constitute by base material, the coat of metal and protective seam; Directly on smooth substrate surface, plate can reflection ray the coat of metal (being reflector layer); Protective seam is protected on metal coating surface covers then, and this reflector plate does not have light diffusion function, and the light of reflection is inhomogeneous.
Summary of the invention
In order to overcome above-mentioned defective; The invention provides a kind of reflector plate with light diffusion function; This reflector plate with light diffusion function not only has light reflective properties preferably, and has light diffusion function, can make the light reflection more even; Again and the life-span long, simple in structure, easy to implement, can be widely used in all kinds of products that light reflection demand is arranged.
The present invention for the technical scheme that solves its technical matters and adopt is:
A kind of reflector plate with light diffusion function; By base material, be used for the coat of metal of reflection ray and be used to prevent that the coat of metal is destroyed with the protective seam of oxidation forms; The coat of metal is plated on substrate surface; Protective seam covers the coat of metal, and the surface of contact of the said base material and the said coat of metal is concavo-convex alternate out-of-flatness face.
Further technical scheme of the present invention is:
The surface of contact of the said coat of metal and said protective seam is concavo-convex alternate out-of-flatness face.
Said base material is a plastic sheet.This base material can adopt plastic sheets such as PET, PP, PS, PC.
The said coat of metal is an aluminium coated.This coat of metal is to be formed at substrate surface through the mode that vacuum is plated, and except vacuum aluminum-coated, also can adopt other reflective metal material vacuum to be plated on the substrate surface formation coat of metal.This coat of metal has been the main material layer of reflex, is used for reflection ray, and when irradiate light arrived this coat of metal, the light more than 95% can be reflected back.
Said protective seam is any one in overlay, pouring film, curing glue-line and the transparent ink layer.
The invention has the beneficial effects as follows: of the present invention have the reflector plate of light diffusion function because the surface of contact of its base material and the coat of metal is concavo-convex alternate out-of-flatness face; The surface of contact of the coat of metal and protective seam is concavo-convex alternate out-of-flatness face; At reflex time, what concavo-convex alternate out-of-flatness face took place is diffuse reflection, can make the light expanding; Make the light of reflection more even; And this reflector plate with light diffusion function has light reflective properties preferably, again and the life-span long, simple in structure, easy to implement, can be widely used in all kinds of products that light reflection demand is arranged.

Embodiment
Embodiment: a kind of reflector plate with light diffusion function; By base material 1, be used for the coat of metal 2 of reflection ray and be used to prevent that the coat of metal is destroyed with the protective seam 3 of oxidation forms; The coat of metal 2 is plated on base material 1 surface; Protective seam 3 covers the coat of metal 2, and said base material 1 is concavo-convex alternate out-of-flatness face with the surface of contact of the said coat of metal 2.
The surface of contact of the said coat of metal 2 and said protective seam 3 is concavo-convex alternate out-of-flatness face.
Said base material 1 is a plastic sheet.This base material specifically can be used plastic sheets such as PET, PP, PS, PC.
The said coat of metal 2 is an aluminium coated.This coat of metal is to be formed at substrate surface through the mode that vacuum is plated, and except vacuum aluminum-coated, also can adopt other reflective metal material vacuum to be plated on the substrate surface formation coat of metal.This coat of metal has been the main material layer of reflex, is used for reflection ray, and when irradiate light arrived this coat of metal, the light more than 95% can be reflected back.
Said protective seam 3 is any one in overlay, pouring film, curing glue-line and the transparent ink layer.
