Abstract

The utility model belongs to the technical field of the backlight unit structure technique and specifically relates to a side income formula backlight unit structure, which comprises a back plate, the equal fixed mounting in both sides of backplate inner wall has L ED lamp strip, the bottom fixed connection of backplate inner wall has end reflector plate, cut apart into two light guide plates with the light guide plate, reserve the space of light guide plate inflation between two light guide plates cut apart, avoid the problem of light guide plate inflation dome lamp, set up specular reflection piece on the reflector plate below the clearance of the light guide plate inflation of reserving between two light guide plates cut apart, can carry out the even diffusion to the light in the clearance, reach the purpose of diffused light, accessible printing site or through the proportion that changes reflectivity and scattering rate realize the luminance value that needs on above-mentioned specular reflection piece, through leaving the gap between light guide plate and the L ED lamp strip, played the convenient distance of maintaining between light guide plate and the L ED lamp strip, avoid the light guide plate inflation to cause the less problem in clearance.

Description

Side-in type backlight module structure

Technical Field

The utility model relates to a backlight unit technical field especially relates to a side income formula backlight unit structure.

Background

In the prior art, the backlight source with ordinary brightness basically adopts a single-edge light incidence mode, but for the side-edge light incidence module with the brightness exceeding 600nits, single-edge light incidence cannot be realized, if double-long-edge light incidence is adopted, but double-edge light incidence can cause the problems that the light guide plate expands the top lamp, the light guide plate expands the top screen, the space between the light guide plate and the L ED lamp can not be maintained easily because of the expansion of the light guide plate, and the like.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving and having the bilateral income meeting among the prior art and leading to light guide plate inflation dome lamp, light guide plate inflation top screen, the shortcoming that can't keep the scheduling problem because the light guide plate inflation easily between light guide plate and the L ED lamp, and the income formula backlight unit structure of inclining that proposes.

In order to achieve the purpose, the utility model adopts the technical scheme that the lateral entering type backlight module structure comprises a back plate, L ED lamp strips are fixedly arranged on two sides of the inner wall of the back plate, a bottom reflector plate is fixedly connected to the bottom of the inner wall of the back plate, light guide plates are fixedly connected to two sides of the top of the bottom reflector plate, a gap is reserved between the light guide plates, a mirror surface reflector plate is fixedly connected to the top of the bottom reflector plate and positioned between the two light guide plates, and a diffusion sheet is connected to the inner wall of the back plate and positioned above the light guide plates.

Preferably, the L ED lamp strip is on a horizontal line with the light guide plate, and a gap is left between the L ED lamp strip and the light guide plate.

Preferably, the specular reflection sheet is strip-shaped, the width of the specular reflection sheet is smaller than the width of a gap between the two light guide plates, and dots are arranged on the surface of the specular reflection sheet.

Preferably, the upper diffusion sheet is fixedly connected to the inner wall of the back plate and located at the opening edge.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the light guide plate is divided into two light guide plates, and an expanded space of the light guide plate is reserved between the two divided light guide plates, so that the problem of an expanded top lamp of the light guide plate is solved.

2. The mirror reflection sheet is arranged on the reflection sheet below the expanded gap of the light guide plate reserved between the two divided light guide plates, light in the gap can be uniformly diffused, the purpose of diffusing the light is achieved, and the required brightness value can be achieved on the mirror reflection sheet through printing mesh points or through changing the proportion of reflectivity and scattering rate.

3. Through keeping being equipped with the gap between light guide plate and the L ED lamp strip, played the distance that conveniently maintains between light guide plate and the L ED lamp strip, avoided the light guide plate inflation to cause the less problem in clearance between the two.

Drawings

Fig. 1 is an exploded perspective view of a side-entry backlight module according to the present invention;

fig. 2 is a front view of a side-in type backlight module according to the present invention.

In the figure, a back plate 1, L ED lamp strips 2, a bottom reflecting sheet 3, a light guide plate 4, a mirror reflecting sheet 5 and an upper diffusion sheet 6.

Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

As shown in fig. 1-2, side income formula backlight unit structure, including backplate 1, a serial communication port, the equal fixed mounting in both sides of 1 inner wall of backplate has L ED lamp strip 2, reflector plate 3 at the bottom of the bottom fixed connection of 1 inner wall of backplate, the equal fixedly connected with light guide plate 4 in both sides at the top of reflector plate 3 at the bottom, L ED lamp strip 2 and light guide plate 4 are on a horizontal line, and it is equipped with the space to leave between L ED lamp strip 2 and the light guide plate 4, reflector plate 3 through setting up at the bottom, play and carry out the effect of reflection diffusion to the light that diffuses to 1 bottom of backplate through light guide plate 4, leave between light guide plate and L ED lamp strip 2 and be equipped with the gap, played and conveniently maintained the distance between light guide plate 4 and L ED lamp strip 2, avoid light guide plate 4 inflation to cause the.

Leave between two light guide plates 4 and be equipped with the space, bottom reflector plate 3's top and be located the gap fixedly connected with specular reflection piece 5 between two light guide plates 4, specular reflection piece 5 is the strip, and the width is less than the gap width between two light guide plates 4, specular reflection piece 5's surface is provided with the site, set up specular reflection piece 5 on bottom reflector plate 3 below the clearance of reserving light guide plate 4 inflation between two light guide plates 4 that cut apart, can carry out even diffusion to the light in the clearance, reach the mesh of diffused light, accessible printing the site on above-mentioned specular reflection piece 5 and change the proportion of reflectivity and scattering rate and realize the luminance value that needs.

The upper diffusion sheet 6 is connected to the inner wall of the back plate 1 and above the light guide plate 4, the upper diffusion sheet 6 is fixedly connected to the inner wall of the back plate 1 and located at the edge of the opening, the inner wall of the back plate 1 is shielded by arranging the diffusion sheet 6, and light rays diffused in a reflection mode are further diffused, so that the light rays are diffused more uniformly.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the principles of the present invention may be applied to any other embodiment without departing from the spirit and scope of the present invention.
