Description

Technical Field

[0001] This utility model relates to the technical field of light sources, and in particular to an integrated backlight. Background Technology

[0002] Please refer to the following: Figure 1 and Figure 2 Existing backlights typically include a housing 1, a lamp panel 2, and a diffuser plate 3. The lamp panel 2 is housed within the housing 1, and the diffuser plate 3 covers the slots on the housing 1. The diffuser plate 3 diffuses the light emitted by the internal lamp panel 2 outwards in a diffuse reflection manner to improve the uniformity of illumination. Specifically, the existing housing 1 is usually designed as a structure including a base plate 13 and multiple side plates 14. During installation, adjacent side plates 14 need to be locked together, and all side plates 14 also need to be locked together with the base plate 13. Therefore, the split housing 1 has the disadvantage of low assembly efficiency, which cannot meet the demand for high-efficiency production of light sources. Moreover, the total cost of separately processing the base plate 13 and multiple side plates 14 is high, which cannot meet the demand of manufacturers for low-cost procurement of light sources. In addition, the split housing 1 inevitably suffers from poor heat dissipation performance, which will have a significant impact on the lifespan of the internal lamp panel 2.

[0003] Therefore, improvements to existing technologies are necessary.

[0004] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

[0013] In one of the technical solutions, the diffuser plate has multiple through holes, and the main body has multiple threaded holes on the side facing the diffuser plate, with the positions of the multiple threaded holes corresponding one-to-one with the positions of the multiple through holes.

The main body has a clearance hole, the cable passes through the clearance hole into the mounting groove and is electrically connected to the lamp board, and a connector is connected to the end of the cable away from the lamp board.

[0015] Compared with the prior art, the integrated backlight provided by this utility model has at least the following beneficial effects:

[0016] This solution designs the housing as a one-piece die-cast structural component. During assembly, the lamp board is simply fixed inside the housing, and then the diffuser plate is installed on the housing to cover the slot of the mounting groove, thus completing the backlight assembly.

[0030] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Please refer to the following: Figures 3 to 6 This utility model provides an integrated backlight, mainly comprising a housing 1, a lamp board 2, and a diffuser plate 3. The housing 1 is a one-piece die-cast structural component, specifically including a main body 11 and a heat dissipation part 12. The main body 11 has a mounting groove 111, within which the lamp board 2 is housed. The lamp board 2 can be understood as including a circuit board and multiple LEDs mounted on it. The diffuser plate 3 covers the opening of the mounting groove 111, and is used to diffuse the light emitted by the lamp board 2 outwards in a diffuse reflection manner, thereby improving the uniformity of the backlight's illumination. The heat dissipation part 12 protrudes from the outer wall of the main body 11, and is preferably designed to include multiple heat dissipation blocks 121 protruding from the main body 11 and spaced apart.

[0033] Specifically, this solution designs the housing 1 as a one-piece die-cast structural component. During assembly, the lamp plate 2 is simply fixed in the mounting groove 111 of the housing 1, and then the diffuser plate 3 is installed on the housing 1 to cover the opening of the mounting groove 111, thus completing the backlight assembly. Compared with the existing split-type housing 1, the housing 1 using this solution obviously has higher light source assembly efficiency, which can improve the production efficiency of the backlight. Moreover, the cost of the die-cast housing 1 is lower than the total cost of the base plate and multiple side plates, thus reducing the production cost of the backlight. In addition, the one-piece housing 1 obviously has better heat dissipation performance than the split-type housing 1, and this solution also integrates a heat dissipation part 12 on the housing 1, which can further improve the heat dissipation performance of the backlight, thereby helping to extend the service life of the lamp plate 2.

[0034] Please refer to the following: Figure 4 and Figure 5 The lamp board 2 is preferably fixed to the bottom of the mounting groove 111, and the heat dissipation part 12 protrudes from the side of the main body 11 facing away from the opening of the mounting groove 111. This facilitates the fixing of the lamp board 2 and allows the lamp board 2 to be as close as possible to the heat dissipation part 12, thereby improving the assembly efficiency of the lamp board 2 and also improving the heat dissipation performance of the backlight. Preferably, a heat-conducting component 4 is provided between the lamp board 2 and the bottom of the mounting groove 111. The heat-conducting component 4 can increase the heat conduction area of ​​the lamp board 2 and the outer shell 1, further improving the heat dissipation performance of the backlight. The heat-conducting component 4 is preferably a silicone component with good thermal conductivity.

[0035] Please see Figure 7The main body 11 has a fixing hole 112 on the side facing away from the groove of the mounting groove 111. The fixing hole 112 is located on the outside of the heat dissipation part 12. The fixing hole 112 is a threaded hole or a through screw hole. The outer shell 1 can be fixed in a designated position by passing a bolt through the fixing hole 112.

[0036] Please refer to the following: Figures 4 to 6 The diffuser plate 3 has multiple through holes 31, and the main body 11 has multiple threaded holes 113 on the side facing the diffuser plate 3. The positions of the multiple threaded holes 113 and the multiple through holes 31 are one-to-one. During installation, the diffuser plate 3 can be fixed to the outer shell 1 by passing bolts through the through holes 31 and screwing them into the threaded holes 113.

[0037] Please refer to the following: Figure 3 , Figure 6 and Figure 7 The backlight in this embodiment also includes a cable 5. A clearance hole 114 is provided on the main body 11. The cable 5 passes through the clearance hole 114 into the mounting groove 111 and is electrically connected to the lamp board 2. A connector 6 is connected to the end of the cable 5 away from the lamp board 2. By setting the cable 5 and the connector 6, the external power line can realize the electrical conduction between the lamp board 2 and the external power supply by plugging and unplugging the connector 6. This has the advantage of being easy to connect or disconnect the lamp board 2.

[0038] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
