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.
Utility model content
This utility model provides the concave surface light guide plate of a kind of pair of round dot, and not only operation is few, and qualification rate is high, with short production cycle, and without for specific dimensions, it is easy to implementing, dispersive propagation is uniform, can't see out luminous point, make light softer, identical to visual light brightness at any angle.
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, A face is provided with multiple bead concave point 1, B face is provided with multiple big ball impression point 2, each bead concave point 1 and big ball impression point 2 are all in hemispherical, each bead concave point 1 and big ball impression point 2 are outer from circle, a diameter of the 0.05～5mm of each bead concave point 1, spacing between each bead concave point 1 is 0.05～2mm, the degree of depth of each bead concave point 1 is 0.05～0.9mm, the diameter 0.06～5mm of each big ball impression point 2, the degree of depth of each big ball impression point 2 is 0.05～0.9mm, spacing between each big ball impression point 2 is 0.04～2mm, 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, concave surface according to the double round dot of diffraction theory employing 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, and without for specific dimensions, easy to implement, dispersive propagation is uniform, can't see out luminous point, make light softer, identical to visual light brightness at any angle.

Detailed description of the invention
By optimal embodiment, this utility model is described in detail below.
As Figure 1-3, 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, A face is provided with multiple bead concave point 1, B face is provided with multiple big ball impression point 2, each bead concave point 1 and big ball impression point 2 are all in hemispherical, each bead concave point 1 and big ball impression point 2 are outer from circle, a diameter of the 0.05～5mm of each bead concave point 1, spacing between each bead concave point 1 is 0.05～2mm, the degree of depth of each bead concave point 1 is 0.05～0.9mm, the diameter 0.06～5mm of each big ball impression point 2, the degree of depth of each big ball impression point 2 is 0.05～0.9mm, spacing between each big ball impression point 2 is 0.04～2mm, 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, concave surface according to the double round dot of diffraction theory employing 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, and without for specific dimensions, easy to implement, dispersive propagation is uniform, can't see out luminous point, make light softer, identical to visual light brightness at any angle.
Last 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.
