Abstract
The utility model discloses a light guide plate of parabolic dish relates to geometrical optics's dispersed propagation field, especially relates to the technical field of light guide plate, characterized in that: the light guide plate constitute by two kinds of different guiding light face of A guiding light face and B guiding light face, a guiding light face be equipped with many recess leaded light posts, recess leaded light post be and throw the thing column, the degree of depth of every recess leaded light post be 0.05~0.9mm, string of a musical instrument distance between the 0.05~2mm of parabola opening width, every recess leaded light post is 0~2mm, B guiding light face be smooth mirror surface, the thickness of light guide plate is 0.5~6mm, the utility model discloses not only the process is few, and the qualification rate is high, and production cycle is short, and the cost is lower, need not in addition to specific size, and easy to carry out, the dispersion is propagated evenly, can't see out the luminous point, makes light softer and have a stronger light guide effect.
Description
Technical field
This utility model relates to the dispersive propagation field of geometric optics, especially relates to the technical field of light guide plate.
Background technology
Light guide plate the most in the art is used among various display, such as LED flat lamp, flat pannel display and the backlight module of television set, light guide plate typically uses plastic plate or sheet, enter luminous point and be arranged on side or the surrounding of light guide plate, by sags and crests light source reflected and scatter, make light source become soft uniformly, tradition is to make by the way of laser dotting or ink silk screen printing on smooth base material, process various sizes of product needed according to different layout designs, requirement to producing is strict, operation is various, processing cost is high, production cycle is long, easily batch type occurs that leaded light dispersion is uneven, loss brightness.
Summary of the invention
This utility model provides the light guide plate of a kind of parabolic cylinder, and not only operation is few, and qualification rate is high, with short production cycle, cost is lower, and without for specific dimensions, it is easy to implement, dispersive propagation is uniform, can't see out luminous point, makes light softer and have higher light guide effect.
For solving the problems referred to above, this utility model adopts the following technical scheme that described light guide plate is made up of two kinds of different light guiding surfaces of A light guiding surface and B light guiding surface, described A light guiding surface is provided with a plurality of groove light-guiding pillar 1, described groove light-guiding pillar 1 is in parabolic column, the degree of depth of every groove light-guiding pillar 1 is 0.05～0.9mm, parabola A/F 0.05～2mm, the string of a musical instrument between every groove light-guiding pillar 1 is away from for 0～2mm, described B light guiding surface is smooth mirror surface, and the thickness of described light guide plate is 0.5～6mm.
Among geometric optics, the critical dimensions of optics depends primarily on the shape of propagation medium, size, distance, just the shape left and right forwards, backwards all directions up and down along propagation medium are propagated, according to diffraction theory employing of the present utility model parabolic cylinder, in conjunction with above-mentioned size parameter, and this structure can use extruded method to produce, make without the laser dotting in later stage or the mode of ink silk screen printing, so arbitrarily can cut according to the demand of product, not only operation is few, qualification rate is high, with short production cycle, cost is lower, and without for specific dimensions, easy to implement, dispersive propagation is uniform, can't see out luminous point, make light softer, and there is higher light guide effect.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is cross-sectional schematic of the present utility model.
Detailed description of the invention
By optimal embodiment, this utility model is described in detail below.
As shown in Figure 1-2, described light guide plate is made up of two kinds of different light guiding surfaces of A light guiding surface and B light guiding surface, described A light guiding surface is provided with a plurality of groove light-guiding pillar 1, described groove light-guiding pillar 1 is in parabolic column, the degree of depth of every groove light-guiding pillar 1 is 0.05～0.9mm, parabola A/F 0.05～2mm, and the string of a musical instrument between every groove light-guiding pillar 1 is away from for 0～2mm, described B light guiding surface is smooth mirror surface, and the thickness of described light guide plate is 0.5～6mm.
Among geometric optics, the critical dimensions of optics depends primarily on the shape of propagation medium, size, distance, just the shape left and right forwards, backwards all directions up and down along propagation medium are propagated, parabolic cylinder is used according to diffraction theory is of the present utility model, in conjunction with above-mentioned size parameter, and this structure can use extruded method to produce, make without the laser dotting in later stage or the mode of ink silk screen printing, so arbitrarily can cut according to the demand of product, not only operation is few, qualification rate is high, with short production cycle, cost is lower, and without for specific dimensions, easy to implement, dispersive propagation is uniform, can't see out luminous point, make light softer, and there is higher light guide effect.
It is last that it is noted that obviously above-described embodiment is only for clearly demonstrating this utility model example, and not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also cannot all of embodiment be given exhaustive.And the obvious change thus amplified out or variation still in protection domain of the present utility model among.
