Description

Light display device

Technical field

The utility model relates to a kind of light display device, more particularly, relates to a kind ofly utilize a plurality of light sources to show the light display device of different colours figure that light is formed simultaneously.

Background technology

Light display device has been widely used in advertising lamp box, Christmas gift and each electronic product to strengthen decorative effect.In the prior art; light display device only has single light source usually; for strengthening lighting effects; light display device also can comprise a control circuit usually; light source can be under the indication of control circuit turn colors and light and shade state regularly; because a plurality of light sources in the same space mixed color phenomenon can take place, this light display device is difficult to show simultaneously the formed figure of different colours light, thereby has reduced decorative effect.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of light display device, and it can utilize a plurality of light sources to show the formed figure of different colours light simultaneously.

The technical solution of the utility model is: a kind of light display device is provided, it comprises at least two light sources and light shows district, between described light source and described light shows district, be provided with the first polaroid group and the second polaroid group, the described first polaroid group has the quantity polaroid corresponding with described light source and blocks respectively on the exit direction of described light source, the described first polaroid group has two parts, and the polarizing axis of first's polaroid is vertical with the polarizing axis of second portion polaroid; The described second polaroid group has at least two polaroids, also have two parts, the polarizing axis of its first's polaroid is vertical with the polarizing axis of first's polaroid of the first polaroid group, and the polarizing axis of its second portion polaroid is vertical with the polarizing axis of the second portion polaroid of the first polaroid group.

Compared with prior art, technique scheme utilizes polaroid only to allow the characteristic of passing through at the light wave that some directions shake, between light source and light shows district, be provided with the first polaroid group and the second polaroid group, after the light that Different Light penetrates simultaneously passes through first, second polaroid group respectively, can in the light shows district, show simultaneously.

Fig. 2 is another STRUCTURE DECOMPOSITION schematic diagram embodiment illustrated in fig. 1.

The specific embodiment

In order to make the technical problems to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Please refer to Fig. 1 and Fig. 2, be a preferred embodiment of the utility model light display device, this light display device comprises light source 1 and light shows district 4.Between light source 1 and light shows district 4, be provided with the first polaroid group 2 and the second polaroid group 3; The first polaroid group 2 has the corresponding polaroid of quantity and light source 1 and blocks respectively on the exit direction of light source 1, and it has two parts, and the polarizing axis of first's polaroid 21 is vertical with the polarizing axis of second portion polaroid 22; The second polaroid group 3 has at least two polaroids, also have two parts, the polarizing axis of its first's polaroid 31 is vertical with the polarizing axis of first's polaroid 21 of the first polaroid group 2, and the polarizing axis of its second portion polaroid 32 is vertical with the polarizing axis of the second portion polaroid 22 of the first polaroid group 2.

The quantity of light source 1 can be two, also can be for a plurality of, they can have different colors, in the present embodiment, the quantity of light source 1 is two, i.e. light source 11 and light source 12, correspondingly, the first's polaroid 21 and the second portion polaroid 22 of the first polaroid group 2 only have a polaroid respectively, and their polarizing axis is orthogonal.The polaroid quantity of the second polaroid group 3 can be a plurality of, and in the present embodiment, the polaroid quantity of the second polaroid group 3 is a plurality of.

Like this, because the characteristic that polaroid only allows the light wave in the vibrations of some directions to pass through, the light that light source 11 sends just becomes linearly polarized light during by first's polaroid 21, because the polarizing axis of first's polaroid 31 of the second polaroid group 3 is vertical with the polarizing axis of first's polaroid 21 of the first polaroid group 2, this linearly polarized light can only be by the second portion polaroid 32 of the second polaroid group 3, in like manner, the light that light source 12 sends can only be by first's polaroid 31 of the second polaroid group 3, light source 11,12 light that sent can show in light shows district 4 simultaneously.

Between two adjacent light source 11,12, be provided with an isolation part 13 so that adjacent light source 11,12 is isolated mutually, certainly, also can directly polaroid be bent into arc to isolate adjacent light source 11,12.For strengthening the decorative effect of light, light source 11,12 can have color not of the same race, and can in light display device, establish a control circuit (not shown), make light source 11,12 turn colors and light and shade state regularly under the indication of control circuit, first,

second part polaroid

31,32 of the second polaroid group 3 arrangement that intermeshes.

For making the light diffusion uniformly that sees through the second polaroid group 3 and passing on; be provided with a light diffusing sheet 41 in the second polaroid group, 3 outsides; establish pattern or decorative pattern on the light diffusing sheet 41 to strengthen the effect of the shown figure of light; be provided with a light transmission protecting film 42, the second polaroid groups 3, light diffusing sheet 41 and light transmission protecting film 42 is close together in light diffusing sheet 41 outsides.

In the present embodiment, light display device is one to be the box body of cuboid, and has the holding part 5 and a lid 6 of accommodating light source 1, the first polaroid group 2, the second polaroid group 3 and light shows district 4.Light source 1 is positioned at the inboard of a side of box body, and light shows district 4 is located on the relative another side of box body and light source 1.Certainly, light display device can also be cylinder or spheroid, when light display device is cylinder, light source 1 can be placed a certain position near the cylinder central axis, and light shows district 4 is located on the cylindrical side; When light display device is spheroid, light source 1 can be placed a certain position near ball centre, light shows district 4 is located on the sphere.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
