Abstract
The utility model relates to a round side backlight source, comprising a reflection plate, a light guide plate, a LED side light source and a frame, wherein the frame is arranged on the edges of the reflection plate and the light guide plate; the LED side light source is mounted on the reflection plate, the light guide plate is arranged above the reflection plate; a plurality of round mesh points are arranged on the light guide plate. The round mesh points arranged in a concentric arc are mounted on the light guide plate to greatly increase the use situation of the side back light source.
Description
[technical field]
The utility model relates to a kind of circular side backlight, belongs to the electric lighting technical field.
[background technology]
LED side backlight is luminous because of the back that the extra long life of LED is widely used in the household electrical appliance luminous button.The side backlight refers to the side that LED is installed in light source; Rely on LGP and back side reflector to make light outside uniformly light-emitting in a plane; Become the area source of each position uniformly light-emitting, for various illuminators provide desirable backlight.
At present; The geometric shape of LED side backlight commonly used is rectangle or square; The design of site also is the geometric shape according to LED side backlight in the LGP, therefore, and in some occasion; When the geometric shape that needs LED side backlight is circular, was used for rectangular light guide plate mesh point design in the past and just no longer can uses.
Therefore, for solving the problems of the technologies described above, necessary a kind of structure improved circular side backlight that has is provided, to overcome said defective of the prior art.
[utility model content]
For addressing the above problem, the purpose of the utility model is to provide a kind of circular side backlight with new light guide plate mesh point design.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is: a kind of circular side backlight is characterized in that: comprise reflector, LGP, LED sidelight source and frame; Wherein, said frame is arranged on reflector and LGP outer rim; Said LED sidelight source is installed on the reflector; Said LGP is arranged on the reflector top; Be provided with some circular shaped lattice points in said LGP.
The circular side backlight of the utility model further is set to: said circular shaped lattice point is arranged to several donut structures, and its diameter increases from inside to outside successively.
The circular side backlight of the utility model also can be set to: state the rounded structure of LGP.
Compared with prior art, the utlity model has following beneficial effect: the circular side backlight of the utility model is the circular shaped lattice point that isocentric circular arc is arranged through on LGP, being provided with, thereby the use occasion of this side backlight is increased greatly.
[description of drawings]
Fig. 1 is the profile of the circular side backlight of the utility model.
Fig. 2 is the sketch map of LGP of the circular side backlight of the utility model.
[specific embodiment]
See also shown in Figure of description 1 and 2, the utility model is a kind of circular side backlight, and it is made up of members such as reflector 1, LGP 2, LED sidelight source 3 and frames 4.
Wherein, wherein, LED sidelight source 3 equally spaced being installed on the reflector 2.
Said LGP 2 is arranged on reflector 1 top, and its concrete shape can be circular configuration.Be provided with some circular shaped lattice points 21 in said LGP 2; These circular shaped lattice points 21 are arranged into several donut structures; Its diameter increases from inside to outside successively; The size that is circular shaped lattice point 21 is along with the distance away from LED sidelight source 3 increases and increases, and the scope of variation is 0.22 millimeter and increases to 0.33 millimeter.
Said frame 4 is arranged on reflector 1 and LGP 2 outer rims, thereby with whole side backlight encapsulation.
The above specific embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection domain of this creation.
Claims (3)
1. a circular side backlight is characterized in that: comprise reflector, LGP, LED sidelight source and frame; Wherein, said frame is arranged on reflector and LGP outer rim; Said LED sidelight source is installed on the reflector; Said LGP is arranged on the reflector top; Be provided with some circular shaped lattice points in said LGP.
2. circular side backlight as claimed in claim 1 is characterized in that: said circular shaped lattice point is arranged to several donut structures, and its diameter increases from inside to outside successively.
