Abstract

The utility model provides a light conducting plate, includes a rectangular plate body, the plate body upper surface is guiding light face, the plate body lower surface is for going out the plain noodles, the both sides face that the plate body is relative is established respectively to going into the plain noodles, the last leaded light point that is equipped with a plurality of evenly distributed of guiding light face, be equipped with a plurality of arc bosss on the income plain noodles in proper order, the plate body lower surface has set firmly an excitation layer. The utility model provides a light conducting plate sets up the arc boss on two income plain noodles, the arc boss can increase the angle of incident light, makes the light that gets into in the plate body even, the utility model discloses in, the light source that gets into in the plate body adopts single light source, and single light source is brighter, propagates in the plate body, and the optical loss is less, in the time of in single light source enters into the plate body, through leaded light point scattering to excitation layer, is excited the formation white light, has improved the light luminance that the plain noodles.

Description

Light guide plate

Technical field

The utility model relates to a kind of light guide plate.

Background technology

At present, the incident light source of existing light guide plate is all generally adopt white light incident, but white light is complex light, and wavelength coverage is relatively wider, and the refractive direction in light guide plate is different, and in communication process, light has certain loss, and light emission rate is low.

Utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of uniform in light emission and the high light guide plate of light emission rate.

The utility model realizes like this, a kind of light guide plate, comprise a rectangular plate body, described plate body upper surface is light guiding surface, described plate body lower surface is exiting surface, and the two sides that described plate body is relative are set to incidence surface respectively, and described light guiding surface is provided with some equally distributed light guiding points, described incidence surface is provided with multiple arc boss successively, and described plate body lower surface is installed with an excitation layer.

Particularly, the xsect of described light guiding points is the inverted trapezoidal that top is large, bottom is little.

Particularly, the distribution of described light guiding points is encrypted in the middle part of described plate body gradually from described incidence surface.

The light guide plate that the utility model provides, two incidence surfaces arrange arc boss, and arc boss can increase the angle of incident light, make the uniform light entered in plate body; In the utility model, the light source entered in plate body adopts single light source, and single light source is brighter, propagate in plate body, light loss is less, when single light source enters in plate body, scatter to excitation layer through light guiding points, be excited formation white light, improves the light luminance of exiting surface.

Accompanying drawing explanation

In order to be illustrated more clearly in the technical solution of the utility model, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 1 is the schematic diagram of the light guide plate that the utility model provides.

Fig. 2 is the cut-open view along A-A direction in Fig. 1.

Fig. 3 is the schematic diagram of light guiding points in the light guide plate that provides of the utility model.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.

As shown in Fig. 1 ~ Fig. 3, a kind of light guide plate that the utility model embodiment provides, comprise a rectangular plate body 1, plate body 1 upper surface is light guiding surface 11, plate body 1 lower surface is exiting surface 12, the two sides that plate body 1 is relative are set to incidence surface 13 respectively, in the present embodiment, the two sides being preferably Width are incidence surface 13, this kind of design both can make to enter the uniform light in the middle part of plate body 1, also reduce the use number of light source (not shown) simultaneously, reduce cost, light guiding surface 11 is provided with some equally distributed light guiding points 14, incidence surface 13 is provided with successively multiple arc boss 15, plate body 1 lower surface is installed with an excitation layer 2.

The light guide plate that the utility model provides, two incidence surfaces 13 arrange arc boss 15, and arc boss 15 can increase the angle of incident light, makes to enter the uniform light in plate body 1; In the utility model, the light source entered in plate body 1 adopts single light source, and single light source is brighter, propagate in plate body 1, light loss is less, when single light source enters in plate body 1, scatter to excitation layer 2 through light guiding points 14, be excited formation white light, improves the light luminance of exiting surface 12.

Particularly, the xsect of described light guiding points 14 is the inverted trapezoidal that top is large, bottom is little, incident light can be scattered on light guiding points 14 by incidence surface 13, light can be reflexed to exiting surface 12 uniformly bottom light guiding points 14, because light guiding points 14 xsect is the inverted trapezoidal that top is large, bottom is little, light guiding points 14 sidewall also can reflect and catadioptric accordingly, thus the incident light that incidence surface 13 is scattered scatters to exiting surface 12 through light guiding points 14, reaches the object producing uniform source of light.

Particularly, the distribution of described light guiding points 14 is encrypted in the middle part of plate body 1 gradually from incidence surface, and light reflects through each light guiding points 14, by the middle part of light reflection to plate body 1, light can being made according to outranging, improving the brightness of light in plate body 1 further.

The above is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
