Abstract
A kind of rainbow thin-plate devices, it comprises at least one substrate, directly is shaped on one deck two-dimensional grating film or the two-layer at least one-dimensional grating film that intersects at a certain angle at least on substrate, forms countless unthreaded holes thus.In the time of before this device is placed any nonmonochromatic source, just can produce multicolour pattern.
Description
The present invention relates to rainbow thin-plate devices, particularly be used as the rainbow thin-plate devices of ornament materials.
China utility application NO.85200328 discloses a kind of grating film rainbow glass.The structure of this glass is that two transparent thin board clampings and gummed are gone up two-layer one-dimensional grating film, makes its groove direction become 90 ° of overlapping placements, and also available one deck crossed grating film replaces the vertical one-dimensional grating film of two-layer groove direction.Just can produce the colorama net before this glass placed ordinary light source.There is complex structure in this glass, the shortcoming that cost is high.At first, make one deck grating film at least, again this film is glued on the glass substrate, be stained with protective seam again, treat the glue drying after, just constituted pearl satin glass.This structure is waste material not only, is difficult to again guarantee bonding homogeneity, also exists transmittance low, the shortcoming of fastness difference.
The purpose of this invention is to provide a kind of improved rainbow thin-plate devices, with the disclosed texture ratio of above-mentioned prior art, the present invention has simpler structure and more reliable usability.
According to the present invention, rainbow thin-plate devices comprises at least one substrate and the two-dimensional grating of one deck at least film that forms at least one first type surface of substrate, certainly, also can at least one interarea of substrate, make the two-layer at least one-dimensional grating film that is crossed as certain angle.Wherein, each group grating line is for being arranged in parallel, and the spacing of groove can be different, and incisure density is 50 to 2400/millimeter, is preferably 100 to 1200/millimeter, constitutes certain angle between two groups of grooves, preferably constitutes to be about 90 °.The grating film is a material with glue such as resins, and substrate can adopt various materials that certain rigidity and physical strength arranged as various glass, organic glass, plastic plate and building materials, paper etc.Utilization printing or other known methods directly built in substrate surface, have just formed rainbow thin-plate devices of the present invention to the grating mould, and certainly, the surface of grating film also can add layer protective layer.
Because the intersection between the grating film groove group has formed countless unthreaded holes, in the time of before rainbow thin-plate devices of the present invention is placed any nonmonochromatic source, will produce multicolour pattern.Along with character, shape, quantity, position, the incisure density of grating film and groove intersecting angle and observer's the position of light source changes, multicolour pattern also correspondingly changes.
The present invention by directly with the grating film built in substrate surface, make structure simpler, this not only easily manufactured cost that also reduced has improved smooth finish and homogeneity, has increased transmittance.
By reference accompanying drawing of the present invention and the description of the drawings, the person skilled in art will have better understanding to the present invention.
Fig. 1 is the front elevation of the amplification of rainbow thin-plate devices of the present invention,
Fig. 2 is the side sectional view of apparatus of the present invention, has represented the state before this device places light source.
In Fig. 2,1 is light source, and it is the nonmonochromatic source that can have various shapes and the characteristics of luminescence; 2 is substrate, and it can adopt glass, lucite, plastic plate, building materials or paper etc., can be transparent or opaque material; 3 is Grating Film, is material with resin etc., with printing or other known methods directly with it on substrate surface; 4 is the colourama net that produces behind light source irradiation.
As seen from the figure, the light that penetrates from the nonmonochromatic source of rainbow thin-plate one side the multicolour pattern that is made of diffraction light occurs at opposite side behind this plate. Certainly, if when substrate adopts opaque material, light source is placed on Grating Film one side, then can produce the colour reflective pattern.
Grating Film rainbow thin-plate devices of the present invention can be used to manufacture various adornments, as: light fixture, toy, furniture, indoor and outdoor building decoration and propaganda advertisement device etc.
In not exceeding following claim limited range, foregoing invention can have various change shape and variations.
