Description

Technical Field

[0001] The utility model belongs to the technical field of backlights, and specifically relates to an improved structure of a vehicle-mounted backlight lamp socket. Background Art

[0002] In the prior art, a display backlight module generally includes components such as a display panel, a light guide plate, a back plate, and a reflector. For the company's mature products, generally, no major changes will be made to its interior to avoid unexpected problems, which would be counterproductive. However, there are inevitably some problems that affect the experience for existing backlights. Specifically, since the position of the light guide plate close to the light source is opposite to the iron frame, after the light source emits light, some of the light will be reflected by the iron frame and then enter the light guide plate again, resulting in problems such as yellowing or dark lines at the lamp socket position. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an improved structure of a vehicle-mounted backlight lamp socket to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] An improved structure of a vehicle-mounted backlight lamp socket includes an iron frame housing. The iron frame housing is successively installed with a reflector, a light guide plate, and a panel assembly from bottom to top. One end of the light guide plate horizontally extends out of the reflector to form a light receiving end. A light source assembly is installed outside the light receiving end. There is a gap between the light source assembly and the reflector, exposing the iron frame housing. The iron frame housing corresponds to the bottom surface of the light receiving end. A color coating is provided at the gap, and the color coating matches the color of the light.

[0006] In a further technical solution, the color coating is formed on the surface of the iron frame housing close to the gap.

[0007] In a further technical solution, the light source assembly includes an FPC circuit board installed at the end of the iron frame housing, and the FPC circuit board extends to the bottom surface of the light receiving end. A plurality of lamp beads and a supporting portion are respectively installed on the FPC circuit board. The plurality of lamp beads correspond to the end of the light receiving end, and the supporting portion abuts against the bottom surface of the light receiving end.

[0008] In a further technical solution, one end of the iron frame housing is bent to form a mounting slot. The light source assembly is installed in the mounting slot. The light receiving end extends into the mounting slot, and the upper end surface of the light receiving end abuts against the end surface of a fixing plate. The other end of the fixing plate extends into the mounting slot and is fixed to its inner wall.

[0009] Advantages of the Utility Model:

[0010] The structure of the present utility model can improve the problem of color difference at the lamp socket without changing the structure of the backlight. Since the component structure is not changed, it will not affect the normal assembly of the backlight, nor is it necessary to re-open the mold for customizing the accessories, thus minimizing the manufacturing cost.

[0011] Other features and advantages of the present utility model will be described in detail in the following specific implementation part. Brief Description of the Drawings

[0014] Reference Signs in the Drawings: Detailed Description of the Preferred Embodiments

[0015] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0016] Please refer to Figure 1-2 ;

[0017] The backlight of the present utility model aims to improve the problem of color difference at the lamp socket position, and specifically includes an iron frame housing 1. A reflector 2, a light guide plate 31, and a panel assembly 4 are sequentially installed on the iron frame housing 1 from bottom to top. One end of the light guide plate 31 horizontally extends out of the reflector 2 to form a light receiving end 32. In this embodiment, the area of the light guide plate 31 is larger than that of the reflector 2, and the area of the finally formed display screen is smaller than or equal to that of the reflector 2. A light source assembly 5 is installed outside the light receiving end 32. Of course, the light source assembly 5 is installed on the iron frame housing 1. There is a gap 6 between the light source assembly 5 and the reflector 2. The iron frame housing 1 corresponds to the bottom surface of the light receiving end 32. It should be noted that the gap 6 is formed by the dimensional limitations of various parts in the prior art. Due to the tolerances of each part, it is impossible to make a completely compact setting, and a certain space needs to be reserved for assembly. The reserved space will expose the iron frame housing 1; after the light source assembly 5 emits light to the light guide plate 31, the light guide plate 31 emits light. The part of the light guide plate 31 corresponding to the gap 6 will directly irradiate the light onto the iron frame housing 1, and the iron frame housing will reflect the light;

[0018] Assume that the lamp bead 52 is a three-primary-color lamp bead 52, composed of red, yellow, and blue. Since yellow has strong penetrability, more yellow light will pass through the light guide plate 31 and reach the surface of the iron frame housing, and then be reflected back into the light guide plate 31 again. At this time, the problem of yellowing at the edge will occur; or the lamp bead 52 is white, and the iron frame housing 1 is black or other colors. After the white light enters the light guide plate 31 and irradiates the surface of the iron frame housing, part of it will be absorbed, resulting in a darker situation at the edge.

[0019] In this embodiment, a color coating 7 is provided at the gap 6. In one implementation manner, the formation of the coating is realized by a nickel plating process; specifically, assume that the lamp bead 52 is a three-primary-color lamp bead 52, and a black coating is set in the gap 6 to absorb the yellow or other small amounts of stray light that overflow from the light guide plate 31, so that it cannot reflect light, thereby solving the problem of yellowing at the edge; assume that the lamp bead 52 is white, then a white coating is set in the gap 6, which can re-emit the light into the light guide plate 31 and play a role in brightening; of course, there are many ways to match the color coating 7 with the light color, which is determined according to the actual situation; through the structure of the present utility model, the problem of color difference at the lamp socket can be improved without changing the structure of the backlight source. Since the component structure is not changed, it will not affect the normal assembly of the backlight source, nor is it necessary to re-open the mold for customizing the accessories, and the manufacturing cost is reduced to the lowest.

[0020] In the embodiment of the present utility model, there are two setting methods for the coating. Specifically, it can be set on the bottom surface of the light guide plate 31 or on the surface of the iron frame housing. If the former is adopted, the range of the coating needs to be accurately controlled, otherwise it will affect the light guiding effect. For example, if the coating area extends to the reflector 2, it will affect the reflected light and instead affect the light emitting effect of the backlight source. If the latter is adopted, the position of the coating does not need to be accurately controlled, and only the position of the gap 6 needs to be covered. Therefore, the latter is preferably adopted.

[0021] It should be noted that the above-mentioned implementation manner mentions that there is a tolerance between the accessories. Therefore, the size of the gap 6 cannot be determined, and it is impossible to cover the gap 6 with standard accessories. If standard accessories are adopted, when the tolerance between the accessories is large, the gap 6 cannot be completely covered, and when the tolerance between the accessories is small, the standard accessories cannot be assembled. However, the problem does not exist when the coating method is adopted.

[0022] One embodiment of the present utility model relates to a light source assembly 5, which specifically includes an FPC circuit board 51 installed at the end of an iron frame housing 1, and the FPC circuit board 51 extends to the bottom surface of the light receiving end 32. A plurality of lamp beads 52 and a supporting portion 53 are respectively installed on the FPC circuit board 51. The plurality of lamp beads 52 correspond to the end of the light receiving end 32, and the supporting portion 53 abuts against the bottom surface of the light receiving end 32. Through such a design, the lamp beads 52 can be as close as possible to the light receiving end 32, reducing the loss of light energy. In addition, since the light receiving end 32 extends out of the reflector 2 without support, the supporting portion 53 is used to support this part.

[0023] In the embodiment of the present utility model, one end of the iron frame housing 1 is bent to form a mounting slot 11, forming an integral structure, reducing the use of parts. The light source assembly 5 is installed in the mounting slot 11, and the light receiving end 32 extends into the mounting slot 11. The upper end surface of the light receiving end 32 abuts against the end surface of the fixing plate 8, and the other end of the fixing plate 8 extends into the mounting slot 11 and is fixed to its inner wall.

[0024] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description.
