Abstract

The utility model belongs to an ultra-thin type light conducting device which is an improvement to the conventional light conducting device. The device comprises an electric light source, a light conducting plate, a box body and a bottom plate and so on. The key technology is that the light conducting plate is the superposition and combination of more than two light conducting slices. One side of the light conducting slice is sprayed with a layer white paint circular point from the large one to the small one and has a vertical row and transverse column and the intersection order. because the white paint circular point of the light conducting plate has the reflection and diffusion effect the lamplight of the device can be uniformly distributed, which can remove the black shadow of the frame edge and has a good soft vision feeling and make the reduction of the thickness of the lamp box possible.

Description

Ultrathin guiding device

Technical field:

The utility model belongs to a kind of ultrathin guiding device, is the improvement to traditional guiding device.

Background technology:

Guiding device often is applied to aspects such as the lamp box making, guideboard guide, exhibition center, photo observation of advertising.The light source of the guiding device of this quasi-tradition is generally used fluorescent tube.Because the observation thing is different with the light source distance, often causes some local light to cross bad visual impression bright or that some local light is dark excessively; Sometimes shadow can occur in the position of edge or the shadow of fluorescent tube on picture screen, occur, have a strong impact on observing effect.It is big slightly that next is that it takes up room, and the thickness of general lamp box is all more than 30mm.

Summary of the invention:

The utility model is to design a kind of both leaded lights, and the ultrathin guiding device of soft even visual impression is arranged again.It is achieved in that by electric light source, light guide plate, casing and bottom panel etc. forms, light guide plate is formed by the light guide sheet stack combinations more than two, and the one side of light guide sheet has capable, horizontal have row and mutual dislocation and descending in order arrangement mode spraying one deck whitewash round dot by indulging.The light guide plate that two equidirectional stack combinations of light guide sheet form is main under the electric light source irradiation to produce unidirectional light, and the light guide plate that two light guide sheet subtend stack combinations form produces bi-directional light under the electric light source irradiation.Various plastic, transparent sheets all can be used as light guide sheet and use.

Because the whitewash round dot on the light guide plate directly shines or the side photograph at electric light source, all has reflection, diffusion effect, thereby the utility model light is evenly distributed, and has good, soft visual impression, and has eliminated the generation of edge shadow.Simultaneously also making lamp box reduce thickness becomes possibility, and the utility model can be made the lamp box that thickness is no more than 10mm, has reduced space occupancy.

Description of drawings:

Fig. 1 is the utility model structure (analyse and observe on the right side) synoptic diagram.

Fig. 2 is the utility model light guide sheet structural representation.

Among the figure: 1 casing, 2 base plates, 3 black paper, 4 opaque blank sheet of paper, 5 light guide plate, 6 picture posters, 7 panels (transparent), 8 electric light sources, 9 light guide sheet, 10 whitewash round dots.

Embodiment:

It is described in detail in detail in conjunction with the accompanying drawings.Referring to Fig. 2, can adopt various plastic, transparent sheets to make light guide sheet 9 uses, light guide sheet 9 one side by vertical row being arranged, horizontal row and mutual dislocation and descending in order arrangement mode spraying one deck whitewash round dot 10 is arranged, two light guide sheet 9 stack combinations are formed light guide plate 5 after to be dried.The round dot 10 that said method sprays out not only has row that row are arranged, and the certain angle that tilts is seen also marshalling.Two blocks of light guide plate 5 unidirectional light of main generation under electric light source 8 irradiations that light guide sheet 9 equidirectional stack combinations form, add the opaque blank sheet of paper 4 of one deck and one deck black paper 3 just can be made unidirection luminous the utility model (see figure 1) at the another side of light guide plate 5, its luminance brightness of sending is than the luminance brightness of U.S. televisor.The light guide plate that two light guide sheet 9 subtend stack combinations form produces bi-directional light under the electric light source irradiation, can make two-way luminous the utility model in view of the above.

According to different requirements, also can form light guide plate by the light guide sheet more than three (9) stack combinations to light.

Claims

1, a kind of ultrathin guiding device, form by electric light source, light guide plate, casing and bottom panel etc., it is characterized in that light guide plate (5) is formed by the light guide sheet more than two (9) stack combinations, the one side of light guide sheet (9) has capable, horizontal have row and mutual dislocation and descending in order arrangement mode spraying one deck whitewash round dot by indulging.

2, ultrathin guiding device according to claim 1 is characterized in that equidirectional stack of two light guide sheet (9) or subtend are superimposed to form light guide plate (5).
