Abstract
The utility model discloses a light guide plate which comprises a transparent light guiding plate. The back of the transparent plate is provided with a plurality of opaque bumps as light guiding spots. The light guiding plate provided by the utility model has a plurality of light guiding spots which can reflect the ray coming from the backward radiation of the light source, and guide the light directionally to the facade of the transparent light guiding plate. The transparent light guiding plate used as the light source of a light lamp box is arranged at the side edge of the light guiding plate, so the transparent light guiding plate can be used for producing super-thin lamp boxes. And due to the excellent light guiding quality of the transparent light guiding plate, while reaching the same luminance, the number of the light source and the power consumption of the lamp box can be substantially reduced.
Description
Technical field
The utility model provides a kind of light guide plate, especially is specially adapted to make a kind of light guide plate of lamp box.
Background technology
Lamp box of the prior art generally all has a very thick casing, the front of this casing sets firmly the lamp box exhibiting pictures, on the boxboard of the back of lamp box, set firmly light source, in order to have uniform light on the picture that is demonstrated that makes this lamp box, will on the area of corresponding picture place several this light sources be set equably on the picture back lamp box wallboard that be demonstrated, this light source is separated with certain distance between also wanting between the picture, otherwise, picture is too near from light source, near the light source light is very inhomogeneous, therefore, the light and shade stick very easily appears on picture.Above-mentioned everything all cause existing lamp box that a very big thickness is arranged.The thickness of general existing lamp box often will reach more than 200 millimeters.Thick like this lamp box, if the area of the picture of being showed is bigger in addition, it takes up space just very big, and firm for it is set firmly, lamp house supporting rack also will be done firmly, and it also can occupy bigger space, increases simultaneously and sets up difficulty.In addition, light source in the existing lamp box will evenly distribute with certain spacing on the area at picture place, just by using fluorescent tube commonly used to come for example as light source, its arranging density is to want a fluorescent tube to be close to a fluorescent tube basically, if not like this, also the light and shade stick will occur on the picture of showing, this will greatly influence the bandwagon effect of lamp box picture.If the picture that is demonstrated is bigger, more than the quantity of the used light source of this lamp box and its energy consumption big be conspicuous.
Fluorescent tube arrange more sparse and cause light that the reason of the light and shade stick on the exhibiting pictures is that fluorescent tube sends to around disperse, wherein shining on the exhibiting pictures is the part of source light.In order to make being demonstrated of lamp box gather light source as much as possible above the picture light and light to be distributed on picture more equably, the general employing established reflecting plate on the prior art on the inwall of lamp box, gets on so that the light of light source is reflexed to picture as much as possible.This method effect is unconspicuous, and also is not resolved for the existing big problem of lamp house thickness.
Summary of the invention
The purpose of this utility model is to improve deficiency of the prior art, provides a kind of and can make light even light guide plate that penetrates on its front of being located at the light source on its side.Can make power saving, ultra-thin lamp box with it.
The purpose of this utility model is achieved in that
The light guide plate that the utility model provides comprises a transparent light guide panel, and it can be to be made by glass, also can be to be made by transparent organic glass, is provided with some opaque protrusions as leaded light point on the back side of this transparent light guide panel.
The crowning of described leaded light point is preferably cambered surface, and the leaded light point can be the hemisphere or the semiellipsoid of projection, and its height of projection is preferably in 0.1～3 millimeter.
Described leaded light point is that ground, a unit is arranged with 9 preferably on described transparent light guide panel, these 9 leaded light points form equidistant dot matrix to be 3 in length and breadth, the size of 9 leaded light points in this unit all is identical with spacing in length and breadth, and size of leaded light point described in the spacing between each unit and each unit and spacing can be inequality.Distance in this unit between each leaded light point is inequality, or more greatly or smaller.Be located at onesize, the same spacing component units of above-mentioned 9 leaded light points and can obtain best photoconduction on the transparent light guide panel to effect.
The leaded light principle of this light guide plate is such: light source such as daylight lamp are placed on the side of this light guide plate, and some passes light guide plate forward the light of light source, and some passes light guide plate backward.For light guide plate general in the prior art, this part light just can't make it to forward to front irradiation, but because the back side of this light guide plate is provided with many protrusion leaded light points, the light that penetrates light guide plate backward can reflect again after injecting described leaded light point, because in everywhere the reflection angle difference thereon of the leaded light point with arcwall face, so, with regard to being arranged, many light that shine backward have been reflected to front irradiation, therefore, the light intensity in the front of this light guide plate has just strengthened greatly.
When making lamp box, the light guide plate that the utility model is provided is located at the back of the picture that is demonstrated, on the periphery of this light guide plate, be provided with light source, as fluorescent tube, downward in the tube groove of the light of light source on the light guide plate periphery, forward, irradiation is come out backward, all can impinge upon on the picture that is demonstrated to forward light to the light of front irradiation with through described leaded light point reflection and used, therefore, use this light guide plate lamp box if light guide plate up and down or about the same or better radiation response of several light sources that light source just can obtain to be closely arranged in the prior art picture back that is demonstrated is set.
For the light that some is shone in the gap between the adjacent leaded light point backward also reflexes to front irradiation, this light guide plate can also include a reflecting plate, and it is located at the back at the back side of described transparent light guide panel.
More even for the light that irradiation is forward come out, this light guide plate can also include a diffusion sheet, and it is located at the front in the front of described transparent light guide panel.
The light guide plate that the utility model provides, it is by being provided with several leaded light points on the back side of transparent light guide panel, the light that light source is shone backward arrives its front by the orientable leaded light of the reflection of leaded light point, because using this light guide plate to make lamphouse light source is provided in a side of on the side of light guide plate, can make ultra-thin lamp box so use such light guide plate, have because the outstanding photoconduction tropism of this light guide plate, reach same illumination, the quantity that light source is set can be reduced significantly, the power consumption of lamp box can be significantly reduced.
