Abstract
The invention relates to a directional light reflecting sheet which is provided with a front light face and a reverse light face. A prism face is arranged above one light face. Multiple directional light reflecting strips are arranged on the prism face in a clamped and embedded mode. A propylene material layer is arranged on an upper plane of each directional light reflecting strip. Particle materials different in refractive indexes are added into the propylene material layers. The upper plane of each directional light reflecting strip is of an arc shape concave down. According to the scheme, the light condensation effect can be achieved, the use effect is improved, due to the direction light reflecting strip structure arranged on the prism face, emergent light is uniform, and the radiance degree is high; the propylene material layers different in refractive index are additionally arranged on the direction light reflecting strips, the surface of the directional light reflecting sheet is more uniform, light transmission can be carried out well, and a light source can be diffused forward and outward well.
Description
Technical field
The present invention relates to a kind of optical model sheet, be specifically related to a kind of directional reflector plate.
Background technology
The existing directional reflector plate for lamp decoration industry, two surfaces of directional reflector plate are all planes, like this for the guide-lighting performance of directional reflector plate and astigmatism performance all poor, can not carry out well light transmission and can not make light source well forward, to external diffusion.
Summary of the invention
For the technical matters of above-mentioned existence, the object of the invention is: propose a kind of directional reflector plate that can improve guide-lighting performance and astigmatism performance.
For achieving the above object, the technical solution used in the present invention is: a kind of directional reflector plate, and described reflecting piece has positive and negative two light faces, is provided with prism facets wherein above a light face, and described prism facets inlay card is provided with many group directional reflective bars; On described directional reflective bar, plane is provided with propylene material layer; The granular materials of different refractivity is added in described propylene material layer.
Improve further as the present invention, on described directional reflective bar, plane is recessed arc-shaped.
Improve further as the present invention, described granular materials is MMA methacrylate.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of directional reflector plate of the present invention program, incorporates prism facets and can reach optically focused effect, and improve result of use, the directional reflective bar structure that prism facets is provided with makes uniform in light emission, and brilliant degree is high; The propylene material layer that directional reflective bar adds different refractivity makes directional reflector plate surface light emitting more even, namely can carry out the transmission of light well, can make light source well forward, to external diffusion.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of a kind of directional reflector plate of the present invention;
Wherein: 1, reflecting piece; 2, prism facets; 3, directional reflective bar; 4, propylene material layer.
Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing 1 is a kind of directional reflector plate of the present invention, described reflecting piece 1 has positive and negative two light faces, be provided with prism facets 2 above a light face wherein, optically focused effect can be reached, improve result of use, above this prism facets 2, inlay card is provided with many group directional reflective bars 3, the upper plane of directional reflective 3 is provided with propylene material layer 4, makes mating plate uniform in light emission, and brilliant degree is high, in propylene material layer 4, add the MMA methacrylate of different refractivity, make directional reflector plate surface light emitting more even.
For the transmission of light can better be carried out, can make light source well forward, to external diffusion, on directional reflective bar 3, planar design is recessed arc-shaped.
Below be only embody rule example of the present invention, protection scope of the present invention is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within rights protection scope of the present invention.
Claims (3)
