Abstract
The utility model provides a light guide plate, including the main part, near bellying of this main part side is equipped with a plurality of LED light source, be equipped with leading light zone in the main part and mend light zone, leading light zone is equipped with the major network point that is the matrix arrangement, each site is circular in the major network point, and the opposite side that the LED light source was kept away from by LED light source one side orientation to distance between each site reduces gradually, mend light zone and be close to the setting of LED light source one side to be equipped with the light filling site, mend light zone and include and be provided with a plurality of functional groups along the LED light source array direction is equidistant in proper order that every functional group includes a plurality of light filling sites. The utility model discloses a cooperation of major network point and light filling site improves near the uneven situation of light guide plate bellying light and shade, and the effect is showing very much, and the distance between each site moves towards the opposite side of keeping away from the LED light source and reduces gradually on one side of the LED light source, and the leaded light is even, effectual, and easy operation need not to wrap up the bellying, and is efficient, with low costs, is fit for the operation of the mass production of mill.
Description
Technical field
This utility model relates to LED field, particularly relates to a kind of light guide plate.
Background technology
Some light guide plate is irregularly shaped, there will be some projections at side, and such light guide plate will seem non-near projection
Chang Liang, light guide plate entirety presents brightness unevenness state, and in order to solve this problem, traditional method is to stick on a piece of adhesive tape in lobe,
So can play certain effect, but there is also certain defect, artificial rubberized fabric efficiency is low, and cost is high, and manual operation can
Light guide plate can be produced and pollute, be not suitable for factory mass production operation.
In view of this, it is necessary to invent a kind of light guide plate solving above-mentioned technical problem.
Summary of the invention
The technical problems to be solved in the utility model, is to provide a kind of light guide plate, including main body, the projection on this body side limit
Being provided with several LED light sources near portion, described main body is provided with main light guide zone and light filling district, and described main light guide zone is provided with in matrix
The major network point of arrangement, in described major network point, each site is rounded, and the distance between each site is directed away from by LED light source side
The opposite side of LED light source is gradually reduced, and described light filling district is arranged near LED light source side, and is provided with light filling site, described benefit
Light district includes being provided with some function groups along LED light source orientation is the most equally spaced, and each function group includes some light filling nets
Point.
Further, described each function group includes along being perpendicular to some rows that LED light source orientation is arranged, the light filling of each row
The quantity of site is directed away from LED light source direction and reduces successively, and the light filling site of each function group is triangularly arranged.
Further, described each function group is successively set near each LED light source axis between any two.
Further, described light filling site is rounded or polygon.
Further, the area that described light filling site projects in main body is less than major network point.
This utility model improves the situation that near light guide plate lobe, light and shade is uneven, effect by the cooperation of major network point and light filling site
Really highly significant, the opposite side that the distance between each site is directed away from LED light source by LED light source side is gradually reduced, and leads
Light is uniform, effective, simple to operate without wrapping up lobe, and efficiency is high, low cost, is suitable for factory mass production operation.
Accompanying drawing explanation
This utility model is further described the most in conjunction with the embodiments.
Fig. 1 is structural representation of the present utility model；
The main light guide zone of description of reference numerals in figure: 1-, 2-light filling district, 3-LED light source.
Detailed description of the invention
As it is shown in figure 1, be a kind of light guide plate as most preferred embodiment of the present utility model, including main body, this body side limit
Lobe near be provided with several LED light sources 3, described main body is provided with main light guide zone 1 and light filling district 2, described leading light
District is provided with major network point arranged in arrays, and in described major network point, each site is rounded, and the distance between each site is by LED light source 3
Side is directed away from the opposite side of LED light source 3 and is gradually reduced, and described light filling district is arranged near LED light source 3 side, and sets
There are light filling site, described light filling district to include along LED light source 3 orientation is the most equally spaced and are provided with some function groups, each
Function group includes some light filling sites.Preferably, the closer to LED light source 3, light is the strongest but is the most easily concentrically formed dark space,
And then described light filling site is arranged to circle or polygon, and the area that light filling site projects in main body is set smaller than main
Site, can be effectively improved this problem.Described each function group includes along being perpendicular to the some of LED light source 3 orientation setting
Row, the quantity of the light filling site of each row is directed away from LED light source 3 direction and reduces successively, and the light filling site of each function group is triangle
Shape arranges.Described each function group is successively set near each LED light source 3 axis between any two, the closer to LED light source,
Light filling site is the most, and such arrangement fully makes up the dark space problem between each LED light source 3, is uniformly drawn by light filling district 2 by light
Lead in main light guide zone 1.The most easily disperseing inequality from LED light source 3 more distance light line, the major network point of the most intensive arrangement will be big
The big problem reducing light inequality.
In sum, this utility model improves light and shade inequality near light guide plate lobe by the cooperation of major network point and light filling site
Situation, effect highly significant, the distance between each site by LED light source side be directed away from the opposite side of LED light source by
The least, guide-lighting uniform, effective, simple to operate without wrapping up lobe, efficiency is high, low cost, is suitable for factory mass
Production operation.
Above in conjunction with accompanying drawing, this utility model is exemplarily described, it is clear that this utility model implements not by above-mentioned side
The restriction of formula, as long as have employed the improvement of the various unsubstantialities that method of the present utility model design is carried out with technical scheme, or not
Improved design of the present utility model and technical scheme are directly applied to other occasion, all at protection domain of the present utility model
Within.
