Description

Light guide device

Technical Field

The utility model relates to a light guide device, in particular to light guide device.

Background

With the development of society and the progress of science and technology, people pursue higher and higher light and shadow efficiency. Referring to fig. 1, there is a light guide device a on the market in which various patterns are formed by light from a light source. The principle is that imaging points 2 are mainly arranged on the surface of a light guide body 1, the positions of the imaging points 2 are correspondingly arranged according to a pattern to be formed, and the imaging points 2 can form refraction and diffusion effects on incident light rays, so that a person can watch the pattern. The light guide body 1 and the imaging points 2 can be integrally formed by injection molding in the early stage, and the imaging points 2 can be formed on the light guide body by carving and the like after the light guide body 1 is formed in the early stage. However, the existing light guide device a has some problems: firstly, the image forming dots 2 are arranged on the surface of the light guide body 1, are easily worn, influence the pattern forming effect and influence the surface beauty; secondly, the imaging points 2 are arranged on the surface of the light guide body 1, the light emitting effect is poor, the light of the formed pattern is dark, the imaging points are only suitable for the plate-shaped light guide body 1, and the imaging effect and the light of the light guide body 1 with arc or various curved surfaces are poorer; thirdly, the light guide body 1 and the imaging points 2 are formed by an injection molding tool, a mold is required to be opened for one pattern, the cost is high, and the imaging points 2 are easy to deform and shrink during injection molding processing to influence the light emitting efficiency of the imaging points; fourthly, forming the imaging points 2 on the light guide 1 by means of engraving and the like, the processing efficiency is slow, and time and labor are wasted.

SUMMERY OF THE UTILITY MODEL

The utility model provides a light guide device, the imaging point of having solved current light guide device arranges on the surface of light conductor, and easy wearing and tearing, the light-emitting effect is not good, only is fit for platelike light conductor, the light conductor of unsuitable arc or various curved surfaces to machining efficiency is low and defect with high costs.

The technical scheme of the utility model is realized like this:

a light guide device comprises a light guide body for light to penetrate through, wherein a plurality of mesh points and/or grains are arranged in the light guide body, and the mesh points and the grains are used for forming refraction and diffuse reflection effects on incident light.

Further, the light guide body is a flat plate, an arc-shaped plate or a special-shaped plate.

Further, the light guide body is a glass plate or a transparent plastic plate.

Further, the mesh points are triangular cylinders, quadrangular cylinders, pentagonal cylinders, hexagonal cylinders, seven-sided cylinders, octagonal cylinders, cylinders or special-shaped cylinders.

Further, the mesh points and the lines are formed by focusing and engraving laser inside the light guide body.

The utility model has the advantages that: the mesh points or lines of the utility model are arranged inside the light conductor, which can not be worn, the light emitting effect is good, and the formed pattern light is good; the light guide body is suitable for various shapes such as plate shape, arc shape and special shape; the net point with the line is in through laser the inside focus sculpture of light guide forms, can carve various shapes, and the richness is good and laser can be one row of scanning sculpture, and machining efficiency is high, and is with low costs.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

FIG. 1 is a schematic structural diagram of a conventional light guide device;

fig. 2 is a schematic structural diagram of a light guide device according to the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 2, a light guide device B includes a light guide body 3 for light to pass through, a plurality of dots 5 and/or lines are provided in the light guide body, and the dots 5 and the lines are used for forming refraction and diffuse reflection effects on incident light.

The light guide body 3 is a flat plate, an arc-shaped plate or a special-shaped plate. The light guide body 3 is a glass plate or a transparent plastic plate. The mesh points 5 are triangular columns, quadrangular columns, pentagonal columns, hexagonal columns, heptagonal columns, octagonal columns, cylinders or special-shaped columns. The mesh points 5 and the lines are formed by focusing and engraving laser inside the light guide body 3.

The mesh point 5 or the grain of the utility model is arranged inside the light conductor 3, which can not be worn, the light emitting effect is good, and the formed pattern light is good; a light guide body 3 adapted to various shapes such as a plate shape, an arc shape, and a special shape; the mesh point 5 with the line is in through laser the inside focus sculpture of light guide body 3 forms, and before the laser sculpture, the pattern that will carve earlier is arranged the point in the CAD picture, then with the leading-in laser engraving machine of CAD cloth point picture, on projecting the light guide body model, then according to the shape of light guide body 3, mesh point and the position of line in light guide body 3, carries out data correction, is in through the laser engraving machine at last the focus sculpture of light guide body 3 inside forms mesh point 5 or line, can carve various shapes, and richness is good to according to CAD cloth point picture, laser can scan the sculpture one row by one row, and machining efficiency is high, and is with low costs.
