Abstract
The invention discloses a medical optical film. The medical optical film comprises two diffusion sheets, lenses, a light guide sheet and a reflector sheet. The medical optical film is characterized in that the lenses are arranged between the diffusion sheets, the light guide sheet is connected below the diffusion sheets, the reflector sheet is connected below the light guide sheet, the lenses comprises a V-shaped lens and an H-shaped lens, and the V-shaped lens is arranged above the H-shaped lens. According to the technical scheme, at least one of line stacking, local adhesion, scratches and wear with other optical components can be effectively improved, and the medical optical film is simple in structure and easy to produce.
Description
Technical field
The present invention relates to medical instruments field, be specifically related to a kind of medical optical diaphragm.
Background technology
Along with the progress of medical science opto-electronics, the requirement of the bright dipping light shape that light source module provides also little by little is increased.Now, blooming piece miscellaneous is just developed, with the various demands because of reply light shape.These blooming pieces comprise diffusion sheet (diffusion sheet), bright enhancement film (brightnessenhancement film, BEF), be such as prismatic lens (prismsheet), lens arra (lensarray) etc.
Summary of the invention
The object of the invention is to overcome prior art Problems existing, a kind of medical optical diaphragm is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of medical optical diaphragm, comprises two panels diffusion sheet, lens, light guide plate and reflector plate, is characterized in that, is provided with described lens between described two panels diffusion sheet, in described two panels diffusion sheet be in below be connected with described light guide plate, be connected with reflector plate below described light guide plate.
Preferably, described lens is respectively V-type lens and H type lens, and described V-type lens is arranged on above described H type lens.
Further, described diffusion sheet, lens, compresses into row adhesion by carrying out heat zone between light guide plate and reflector plate.
Further, described diffusion sheet includes macromolecule resin and diffusion particle.
Further, plastic rubber case 5 is connected with below described reflector plate.
Beneficial effect of the present invention:
Adopt technical solution of the present invention, can effectively improve produce with other optical elements folded line, local stick, scrape injure wear phenomenon at least one of them; And structure is simply easy to produce.
