Abstract
The invention discloses a light guide reflection structure, which is provided with a transparent substrate and a reflection plate. A plurality of light guide points are arranged on a reflection surface of the reflection plate, the transparent substrate is superposed on the reflection surface of the reflection plate, light enters from the transparent substrate, reflected light can diffuse to all angles when the light irradiates to the light guide points on the reflection plate positioned on the back of the transparent substrate, and then the light exists from the front of the transparent substrate by damaging reflection conditions, so that linear light sources can be converted into surface light sources. As the light guide points are arranged on the reflection plate, the light guide reflection structure is convenient for manufacture and high in yield during production, and cost can be reduced.
Description
Technical field
The invention belongs to photoelectric field, be specifically related to a kind of illumination or display with leaded light and catoptric arrangement.
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, reverberation 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.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of guide light reflection structure, 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 present invention for the technical scheme that solves its technical problem 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; Reverberation 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 present invention for the further technical scheme that solves its technical problem 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 invention has the beneficial effects as follows: guide light reflection structure of the present invention 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, reverberation 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 present invention 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.

Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below through specific instantiation the specific embodiment of the present invention is described, the personage who is familiar with this skill can understand advantage of the present invention and effect easily by the content that this specification disclosed.The present invention also can other different mode implement, and, not being contrary under disclosed category, 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; Reverberation 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 the illustrative principle of the invention and effect thereof, but not is used to limit the present invention.Rights protection scope of the present invention should be listed like claims.
