Abstract
The utility model discloses a prismatic surface light guide plate 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 tongue leaded light posts, tongue leaded light post be isosceles triangular prism shape, the height of every tongue leaded light post is 0.05~0.9mm, the bottom surface 0.05~0.9mm of width of tongue leaded light post, the vertex angle of tongue leaded light post is 10~120, the bottom of every tongue leaded light post links to each other, B guiding light face be plain noodles or mirror surface, the utility model discloses separate that not only the process is few, the qualification rate is high, and production cycle is short, and low in production cost need not to specific size in addition, and the dispersion is propagated evenly, can't see out the luminous point, the luminance of reducing the loss.
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 guide-lighting uneven, the bad product of the low grade of light efficiency.
Summary of the invention
This utility model provides a kind of prismatic surface light guide plate, and not only operation is few, and qualification rate is high, and with short production cycle, production cost is low, and without for specific dimensions, dispersive propagation is uniform, can't see out luminous point, reduces loss brightness.
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 tongue light-guiding pillar 1, described tongue light-guiding pillar 1 is in isosceles triangular prism shape, the height of every tongue light-guiding pillar 1 is 0.05～0.9mm, the bottom width 0.05～0.9mm of tongue light-guiding pillar 1, the corner angle of tongue light-guiding pillar 1 is 10 °～120 °, the bottom of the tongue light-guiding pillar 1 of every is connected, and described B light guiding surface is bright finish or minute surface.
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 employing isosceles triangular prism shape of the present utility model, in conjunction with above-mentioned size parameter, make light dispersive propagation uniform, can't see out luminous point, light efficiency is strong, 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, reduce production process, improve qualification rate high, shorten the production cycle.
Accompanying drawing explanation
Fig. 1 is cross-sectional schematic of the present utility model.
Fig. 2 is structural representation 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 tongue light-guiding pillar 1, described tongue light-guiding pillar 1 is in isosceles triangular prism shape, the height of every tongue light-guiding pillar 1 is 0.05～0.9mm, the bottom width 0.05～0.9mm of tongue light-guiding pillar 1, and the corner angle of tongue light-guiding pillar 1 is 10 °～120 °, the bottom of the tongue light-guiding pillar 1 of every is connected, and described B light guiding surface is bright finish or minute surface.
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 employing isosceles triangular prism shape of the present utility model, in conjunction with above-mentioned size parameter, make light dispersive propagation uniform, can't see out luminous point, light efficiency is strong, 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, reduce production process, improve qualification rate high, shorten the production cycle.
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.
