Description

Light guide plate structure for backlight source of pin lamp

technical field

The utility model relates to a light guide plate structure of a pin lamp backlight source.

Background technique

With the development of the backlight market, customers have higher and higher requirements for backlight. At present, in order to meet customer needs and achieve the best lighting effect, due to the single plug-in LED of the backlight, the single plug-in LED The assembly with the backlight is fixed with quick-drying glue. At present, the light trough of the light guide plate is a notch structure with a bottom that is arc-shaped, and the side wall is directly connected to the arc. When this kind of light trough is used to fix the LED light with glue, it is easy for the glue to flow to the bottom of the light trough, thereby affecting the backlight. At the same time, there is also the problem that the fixing of the LED light is not reliable enough.

Utility model content

The purpose of this utility model is to provide a light guide plate structure for the backlight of the pin lamp, and solve the problem that the light groove of the light guide plate structure of the existing pin lamp backlight is not reasonable enough to make the glue overflow easily during the assembly process of the LED lamp to the bottom of the light trough, which in turn affects the luminous effect of the backlight.

The technical solution adopted by the utility model to solve the technical problem is: a light guide plate structure for the backlight source of the pin lamp, including a light guide plate body, a light trough arranged at one end of the light guide plate body, the bottom of the light trough is an inverted fan-shaped structure, The left and right side walls of the fan-shaped structure and the left and right side walls of the lamp trough respectively form a chamfer; the distance between the tops of the left and right side walls of the fan-shaped structure is adapted to the lamp holder of the LED lamp.

The left and right side walls of the lamp trough both include an upper side wall, a lower side wall and a concave gap between them, and the bottom of the lower side wall is connected with the side wall of the fan-shaped structure. By setting the concave gap, the amount of glue is increased, and at the same time, it will not cause too much glue to flow down to the bottom of the lamp trough, which improves the fixing effect of the LED lamp, and at the same time will not cause the glue to overflow to the bottom of the lamp trough, affecting the luminescence of the backlight Effect.

Further, the recessed notch has a rectangular structure, and the recessed notches located on the left and right side walls of the lamp trough are arranged symmetrically.

In order to ensure the best fixing effect and the glue will not overflow to the bottom of the light trough, the side wall of the fan-shaped structure extends upwards by 1-2mm from the position where it meets the lower side wall of the light trough.

The beneficial effects of the utility model: by designing the bottom of the light trough to be an inverted fan-shaped structure, and the left and right side walls of the fan-shaped structure and the left and right side walls of the light trough respectively form a chamfer; thus ensuring In the process of flowing down, the glue will be diverted into the chamfer by the chamfer, and will not stay inside the fan-shaped structure, thus effectively solving the problem of the light groove of the light guide plate structure of the existing pin lamp backlight because the design is not reasonable enough, so that During the assembly process of the LED lamp, the glue is prone to overflow to the bottom of the lamp groove, thereby affecting the luminous effect of the backlight source. At the same time, a recessed notch is set on the side wall of the lamp trough, which increases the amount of glue that can be incorporated and improves the fixing effect of the LED lamp.

The utility model will be described in detail below in conjunction with the accompanying drawings and embodiments.

Description of drawings

FIG. 1 is a schematic structural view of a light guide plate of a conventional pin light backlight.

FIG. 2 is a structural schematic diagram of the present invention, and the part of the light guide plate body is omitted.

Detailed ways

Embodiment, as shown in FIG. 2 , a light guide plate structure of a pin lamp backlight source includes a light guide plate body 1, a light groove 2 arranged at one end of the light guide plate body 1, and the bottom of the light groove 2 is an inverted fan-shaped structure 3, The left and right side walls of the fan-shaped structure 3 and the left and right side walls of the light groove 2 form a chamfer 4 respectively; the distance between the tops of the left and right side walls of the fan-shaped structure 3 is compatible with the lamp holder of the LED lamp 5 .

The left and right side walls of the lamp trough 2 all include an upper side wall 6, a lower side wall 7 and a concave gap 8 between the two, and the bottom of the lower side wall 7 is connected to the side wall of the fan-shaped structure 3. The recessed notch 8 has a rectangular structure, and the recessed notches 8 located on the left and right side walls of the lamp groove 2 are arranged symmetrically. The side wall of the fan-shaped structure 3 extends upwards by 1-2 mm from the position where it meets the lower side wall 7 of the lamp groove 2 .

The utility model has been exemplarily described above in conjunction with the accompanying drawings. Apparently, the specific implementation of the present invention is not limited by the above methods. As long as the various insubstantial improvements made by adopting the method concept and technical solution of the present utility model; within the scope of protection.
