Specific implementation mode
Below in conjunction with the attached drawing of the utility model, the technical solution of the utility model is clearly and completely described,
Obviously, the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.Based on this practicality
Embodiment in novel, the every other reality that those of ordinary skill in the art are obtained without creative efforts
Example is applied, shall fall within the protection scope of the present invention.
A kind of heavy wall light guide for realizing the big spacing specular removal uniformly light-emitting of light source that the utility model embodiment is provided, profit
With the total reflection principle of light, the recess being equipped with using heavy wall light guide center, by four of concave interior angled faces flat
Row light is divided into the directional light of four direction all around.
As shown in Figs. 1-5, the transparent material of all glass of heavy wall light guide or organic plastics has one in vertical direction
Determine thickness, heavy wall light guide front end is cuboid 1, the rear portion of the cuboid of heavy wall light guide it is horizontally extending go out it is multigroup identical
Catoptric arrangement 2, catoptric arrangement 2 specifically, edge be zigzag, center downward vertically be equipped with recess, concave interior four
The identical cone of a gore 21；Four gores of cone 21 are 31,32,33,34 (being marked in Fig. 3, Fig. 5)；
External recess is smooth arc-shaped surface cone 22, it can be seen that, is scabbled at the top of smooth arc-shaped surface cone or inwardly reversed in Fig. 3, Fig. 4
Recess 23, it can be seen that, the edge surface of heavy wall light guide has 4 35,36,37,38, edge surface 35 and 36 in Fig. 2, Fig. 3, Fig. 5
The right angled isosceles triangle of the right angled isosceles triangle of composition and edge surface 37 and 38 compositions is symmetrical, makes its entire edge be in
Zigzag.
The trend of light when Fig. 5 illustrates use, when operating, LED circuit board work light LED light source, first with
The light that LED light source is sent out is converted to directional light by collimation lens and paraboloid, uniformly gets to 4 triangles of heavy wall light guide respectively
On shape face 31,32,33 and 34 (shown in Fig. 5).
It is totally reflected on side 38 by the light in 31 faces, being then converted into directional light by secondary total reflection gets to heavy wall
The front end of the cuboid of light guide.Equally, it is totally reflected on side 35 by the light in 33 faces, is then converted by secondary total reflection
The front end of heavy wall light guide is got at directional light.Here, the cooperation of gore 31 and edge surface 38, with gore 33 and edge
The cooperation in face 35, their composite structure make transformed directional light realize the horizontal direction upper edge of heavy wall optical guide unit
Uniformity.
In addition, the light by gore 32 is first totally reflected on subsequent edge surface 36 and 37, then pass through edge surface
35 and 38 are totally reflected and are converted into the front end that directional light gets to heavy wall respectively.Here, gore 32, edge surface 36 and 35 it
Between cooperation, the cooperation of gore 32, edge surface 37 and edge surface 38 makes transformed directional light realize heavy wall light guide list
The uniformity of the middle of center and peripheral in the horizontal direction of member.
As a preferred embodiment of the above technical solution, in Fig. 3, Fig. 4, Fig. 5 it can be seen that, in order to allow the light on gore 34
The uniform center for getting to heavy wall light guide can add some stripeds or tartan to realize the uniform expansion of light on gore 34
It dissipates, meanwhile, in order to realize different function optics light distribution requirements, on the front end face of the cuboid 1 of heavy wall light guide, it also is provided with striped
Or tartan, patterned surface interlock at cambered surface protrusion or staged.
In this example, in order to realize total reflection, angle is 90 degree between face 35 and face 36.Equally, between face 36 and face 37
Angle be 90 degree, angle is 90 degree between face 37 and face 38.Of course it is not excluded the change of structural modeling, between these faces
Angle interval can be selected between 80~100 degree.Face 31,32,33 and 34 and the axis direction of LED light source light emission direction press from both sides
Angle changes adjustment between 30~60 degree, to ensure the heavy wall light guide vertical direction i.e. uniformity of upper and lower directions.
The foregoing is merely the preferred examples of the utility model, utility model are not limited to, for this field
Technical staff for, various modifications and changes may be made to the present invention.Within the spirit and principle of the utility model,
Any modification, equivalent substitution and improvements done, should be included within the scope of protection of the utility model.
