Abstract
The utility model discloses a light guiding reflection structure. The structure is provided with a transparent substrate and a reflecting plate. A reflecting surface of the reflecting plate is provided with several light guiding spots. The transparent substrate is superposed on the reflecting surface of the reflecting plate. Light is penetrated into from the transparent substrate. When the light shines in the each light guiding spot on the reflecting plate located on a back side of the transparent substrate, the reflected light is spread to each angle, a reflection condition is destroyed and the light is emitted from a right side of the transparent substrate so that a line light source can be converted into an area source. According to the structure of the utility model, because the light guiding spots are arranged on the reflecting plate, it is convenient for making in production, a yield rate is high and cost can be reduced.
Description
Technical field
The utility model belongs to photoelectric field, is specifically related to a kind of illumination or display with leaded light and reflection configuration.
Background technology
In the prior art line source being converted into area source realizes through LGP.The LGP of prior art is acrylic (PMMA) sheet material that utilizes optical grade, then with having the high reflectivity and the printing ink of extinction not, the acrylic sheet material bottom surface of optical grade with printing on the leaded light point.The light that utilizes optical grade acrylic sheet material to draw to send from lamp is in the stop on optical grade acrylic sheet material surface, and when light was mapped to each leaded light point, reflected light can destroy conditioned reflex by the positive ejaculation of LGP then toward all angles diffusion.Through various densitys, leaded light point not of uniform size, can make the LGP uniformly light-emitting.LGP generally cooperates reflector plate to use at its back side, in the light reflected back LGP that the purposes of reflector plate is bottom surface of light guide plate is exposed, is used for improving the service efficiency of light.Structure and principle through above-mentioned prior art LGP can know that the leaded light point on the LGP of prior art is directly to be printed on the bottom surface of LGP, and this technology is very difficult in practical operation, and yield is lower, so cost is high.
The utility model content
In order to overcome above-mentioned defective, the utility model provides a kind of guide light reflection structure, and this guide light reflection structure can be converted into area source with line source, and cost is low, simple in structure, easy to implement.
The utility model for the technical scheme that solves its technical matters and adopt is:
A kind of guide light reflection structure is provided with transparency carrier and reflecting plate, has some leaded light points on the reflecting surface of said reflecting plate, and said transparency carrier is superimposed on the reflecting surface of said reflecting plate.Light is injected by the transparency carrier place; When light is mapped to each leaded light point on the reflecting plate that is positioned at the transparency carrier back side; Reflected light can destroy conditioned reflex and penetrate by transparency carrier is positive toward all angles diffusion then, therefore can line source be converted into area source.
The utility model for the further technical scheme that solves its technical matters and adopt is:
Said transparency carrier is glass plate or acrylic board.
Said some leaded light points can directly be printed on the reflecting surface of said reflecting plate; Also can be to be provided with pad pasting, be printed with said some leaded light points on the one side on the said pad pasting, the another side of said pad pasting adheres on the reflecting surface of said reflecting plate.
The beneficial effect of the utility model is: the guide light reflection structure of the utility model is provided with transparency carrier and reflecting plate, has some leaded light points on the reflecting surface of reflecting plate, and transparency carrier is superimposed on the reflecting surface of reflecting plate; Light is injected by the transparency carrier place; When light was mapped to each leaded light point on the reflecting plate that is positioned at the transparency carrier back side, reflected light can destroy conditioned reflex and penetrate by transparency carrier is positive toward all angles diffusion then; Therefore can line source be converted into area source; Because the utility model is arranged at the leaded light point on the reflecting plate, therefore when producing, be convenient to make and the yield height, can reduce cost.

Embodiment
Below through the embodiment of specific instantiation explanation the utility model, the personage who is familiar with this skill can be understood the advantage and the effect of the utility model easily by the content that this instructions disclosed.The utility model also can other different mode be implemented, and, under the category that discloses from the utility model that is not contrary to, can give different modifications and change that is.
Embodiment: a kind of guide light reflection structure, be provided with transparency carrier 1 and reflecting plate 2, have some leaded light points 3 on the reflecting surface of said reflecting plate, said transparency carrier 1 is superimposed on the reflecting surface of said reflecting plate 2.Light is injected by the transparency carrier place; When light is mapped to each leaded light point on the reflecting plate that is positioned at the transparency carrier back side; Reflected light can destroy conditioned reflex and penetrate by transparency carrier is positive toward all angles diffusion then, therefore can line source be converted into area source.
Said transparency carrier is glass plate or acrylic board.
Said some leaded light points can directly be printed on the reflecting surface of said reflecting plate; Also can be to be provided with pad pasting, be printed with said some leaded light points on the one side on the said pad pasting, the another side of said pad pasting adheres on the reflecting surface of said reflecting plate.
The foregoing description is merely illustrative the utility model principle and effect thereof, but not is used to limit the utility model.The rights protection scope of the utility model should be listed like claims.
