Abstract
The utility model discloses a colored light guide plate, comprising a light guide plate and a colored transparent film, wherein a transparent base plate with a plurality of light guide points is arranged on the back surface of the light guide plate; and the colored transparent film is stuck on the front surface of the light guide plate. With the adoption of the light guide plate, the light rays are uniform, and the line light source is converted into a face light source while the color of the light rays is converted by the colored transparent film, therefore, the colored light guide plate has double functions of guiding the light and converting the color of the light ray.
Description
Technical field
The utility model belongs to field of photovoltaic materials, is specifically related to a kind of illumination or display light guide plate.
Background technology
Light guide plate is the high-tech product that line source is converted into area source.The light guide plate of prior art is to utilize the acrylic of optical grade (PMMA) sheet material, then with having high reflectivity and the printing ink of extinction not, the acryl plates bottom surface of optical grade with printing on light guiding points.The light that utilizes the optical grade acryl plates to draw to send from lamp is in the stop on optical grade acryl plates surface, and when light was mapped to each light guiding points, reflected light can toward all angles diffusion, then destroy conditioned reflex and penetrate by light guide plate is positive.By various densitys, light guiding points not of uniform size, can make the light guide plate uniformly light-emitting.Then the light guide plate of prior art can only namely can only be converted into area source with line source with equalizing light rays, and does not possess the function that changes light color.
The utility model content
In order to overcome defects, the utility model provides a kind of coloured light guide plate, and this coloured light guide plate not only has traditional light guide plate with the function of equalizing light rays, and can also change the color of light, again and simple in structure, easy to implement.
The utility model for the technical scheme that solves its technical matters and adopt is:
A kind of coloured light guide plate is provided with light guide plate and coloured printing opacity pad pasting, and described light guide plate is the transparency carrier that the back side has some light guiding points, and described coloured printing opacity pad pasting is covered on the front of described light guide plate.
Described some light guiding points can be shaped in the back side of described transparency carrier.
Described some light guiding points also can be that the printing ink by the back side that is printed in described transparency carrier is consisted of.
Described transparency carrier is glass plate or acrylic board.
The utility model is to form light guiding points at the back side of transparency carrier, this is prior art, can make transparency carrier have light-guiding function, line source can be converted into area source, be traditional light guide plate, and stick coloured printing opacity pad pasting in the front of transparency carrier, can be according to the color transition color of coloured printing opacity pad pasting during this coloured printing opacity pad pasting of light process, therefore coloured light guide plate of the present utility model not only can be converted into area source with line source, and can make light change color.
The beneficial effects of the utility model are: coloured light guide plate of the present utility model is made of light guide plate and coloured printing opacity pad pasting, light guide plate is the transparency carrier that the back side has some light guiding points, coloured printing opacity pad pasting is covered on the front of light guide plate, light guide plate can make light even, be about to line source and be converted into area source, coloured printing opacity pad pasting then can change the color of light, and therefore coloured light guide plate of the present utility model has leaded light and changes the light color dual-use function.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment: a kind of coloured light guide plate, be provided with light guide plate 1 and coloured printing opacity pad pasting 2, described light guide plate is the transparency carrier that the back side has some light guiding points 11, described coloured printing opacity pad pasting is covered on the front of described light guide plate.
Described some light guiding points can be the back side that is shaped in described transparency carrier.
Described some light guiding points also can be that the printing ink by the back side that is printed in described transparency carrier is consisted of.
Described transparency carrier is glass plate.
Described transparency carrier is acrylic board.
Above-described embodiment only is illustrative the utility model principle and effect thereof, but not is used for restriction the utility model.Rights protection scope of the present utility model should be listed such as claims.
