Abstract

The utility model relates to a new optic product, particularly a rainbow film which can be bent and used independently and be glued to the bending or flat surface of objects according to need. The rainbow film can be wiped. Light transmitting or reflected by the rainbow film can be divided into seven-color light. The utility model has the advantages of low cost and simple technology, and is suitable to decorate lamps and lanterns and toys, beautify public places, etc.

Description

Diffracting grating film with able to be deformed function

This utility model is a kind of optics new product.

Background: all be to utilize the technology of replica grating to manufacture transmission or reflection grating in the plane in the past.The grating film always adheres on flat glass or the plane mirror.The always inseparable entity of flat glass or catoptron and grating film, and the utility model when manufacturing grating not with flat glass or catoptron etc., be not that objects such as grating film and flat glass are bonded together inherently.But select to form transparent, tough and tensile rete material, produce and can independently use with the method for replica grating, can be bonded in also that bending (or plane) is lip-deep, tough and tensile, bending deformed grating film.

Because former grating film is the plane, can not bending maybe can only does slight bending, it can not change with the variation of light source form.Therefore its scope of application is comparatively narrow, and this grating has overcome the shortcoming of traditional raster, and it can the flexural deformation with light source or object surface shape.Thereby can utilize this grating film to create new artistic glory by people's will.

Grating film in the past, unless it is clipped in the middle of two slidies (as glass etc.), otherwise can not wiping.And the grating film that makes by the utility model, the equal erasable in two sides.

Technology contents: can form transparent, tough and tensile, wear-resisting film material and become liquid state (fusion or dissolving), water then on the grating mould, after treating its levelling (it being flattened) and film-forming, take off to get final product from the grating mould as flattening or wipeing off.

Here be noted that the film material of selecting for use must be to form transparency height and film material tough and tensile, hard wear resistant here.This class material is a lot.

In order to obtain satisfactory grating film, available a kind of, also which floor available several filmogen pours into a mould.The character of each rete complements each other, and will improve the character of grating greatly.Make that it can independently use, flexible distortion, also can be adhered to other surface.Both the transmission grating film can be manufactured, also the reflection grating film can be made.

When the grating film is adhered to other body surface, fluted one side should be bonded on this body surface.The grating film that obtains so just has not been afraid of wiping.

Technique effect is: the flexible distortion of this grating film, can independently use, and also can be bonded in the transmission or catoptron on bending or plane.This grating handle sees through or reflected white light is decomposed into seven color light.Because the flexible distortion of this grating, thus white light from this grating see through glory that (or reflection) back produces with before plane grating also inequality.Can be more rich and varied.When go up on surfaces such as this grating film being bonded to glass, just made scrubbable grating.

This grating membrane technology is simple, material source wide, be easy to produce (not needing), cost is low.Can be used to decorate furniture, door and window, writing case, photograph album, button, ear pendant etc., can beautify public places such as dance hall, shop.

Accompanying drawing is a rainbow film effect synoptic diagram.(1) is light source among the figure; (2) be white light; (3) be crooked rainbow film; (4) be the colorama net.

Claims

1, a kind of rainbow film is characterized in that going out the grating film with the reprography of replica grating, and it is tough and tensile, and flexible distortion can independently be used.

2, rainbow film according to claim 1 is characterized in that there is groove on grating film surface.

3, rainbow film according to claim 1 is characterized in that pouring into a mould film forming several times with multiple filmogen branch, and each membranous layer property complements each other like this, has just obtained this rainbow film.

4, according to claim 1,2 described rainbow films is characterized in that also can being bonded on other body surface, and as fluted one side and object are joined, just having made outside surface does not have groove not to be afraid of the grating of wiping.
