Description

Technical Field

[0001] This utility model relates to the field of LED light source board technology, and in particular to a waterproof LED light source board backplate. Background Technology

[0002] LED backplate is a key component installed on the back of the LED light source board, which provides support, fixation and heat dissipation. It is usually made of metal materials (such as aluminum), which can provide a solid structural foundation to protect the fragile LED chips and circuits on the board, and can also use its good thermal conductivity to quickly conduct and dissipate the heat generated by the LED during operation, thereby ensuring the stable operation and long life of the LED light source.

[0003] Existing LED backlight panels are installed outdoors or indoors depending on the actual usage requirements. Outdoor backlight panels are constantly exposed to rain. Power cords are usually installed at the rear of the backlight panel. When rainwater falls on the backlight panel and slides down its back wall, it may enter the interior through the gap between the backlight panel and the front cover, which may cause the internal circuit to break and cause safety hazards.

[0004] Therefore, those skilled in the art have provided a waterproof LED light source board backplate to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a waterproof LED light source board backplate. By using a protective plate and drainage pipe set at the upper end of the main frame, rainwater can bypass the power cord and drain out, thus preventing it from entering the interior. At the same time, the sealing gasket set in the rectangular groove at the rear end of the cover frame can effectively prevent rainwater from seeping in from the connection between the cover frame and the main frame, further improving the waterproof performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof LED light source board backplate, comprising a main frame, a protective plate, and a cover frame. The protective plate is fixedly mounted on the upper end of the main frame by screws on both sides. A drainage tube is fixedly mounted on the lower middle part of the protective plate. The body of the drainage tube is embedded in the rear end of the main frame. A wiring hole is opened at the center of the rear end of the main frame. A wiring tube is hinged to the rear end of the wiring hole. A rubber tube is sleeved on the body of the wiring tube. One end of the rubber tube is fixedly mounted at the wiring hole.

[0007] Furthermore, a backlight module is provided inside the front frame of the main body frame, the backlight module includes a backlight source, and the backlight source is fixedly installed on the inner wall of the rear end of the main body frame.

[0008] Furthermore, a light guide plate is provided at the front end of the backlight source, a reflective film is provided at the front end of the light guide plate, a diffusion film is fixedly provided at the front end of the reflective film, and a brightness enhancement film is provided at the front end of the diffusion film.

[0009] Furthermore, a rectangular groove is provided at the rear end of the cover frame, and a sealing gasket is embedded inside the rectangular groove.

[0010] Furthermore, several evenly distributed holes are provided at the front edge of the main frame, and several evenly distributed holes are provided at the edge of the cover frame.

[0011] Furthermore, screws are threaded inside several of the holes one and several of the holes two.

[0012] This utility model has the following beneficial effects: 1. The present invention proposes a waterproof LED light source board back plate. Compared with existing light source board back plates, this back plate has a protective plate at the upper end of the main frame. When rainwater drips onto the protective plate, it will then enter the drainage pipe. The rainwater will then slide down along the drainage pipe, bypass the power cord, and be discharged. In addition, the worker bends the rubber tube downwards, causing the wiring tube to bend simultaneously, so that its opening faces downwards, thereby preventing rainwater from entering the opening of the rubber tube. Through the above method, rainwater can be prevented from entering the interior of the main frame from the power cord, thus improving the safety of the light source board back plate.

[0013] 2. The waterproof LED light source board back plate proposed in this utility model has a sealing gasket embedded in the rectangular groove at the rear end of the cover frame. When rainwater seeps in from the connection between the cover frame and the main frame, the sealing gasket can effectively block the penetration of rainwater, thereby improving the waterproof effect and preventing water from entering the interior.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 1 - Figure 4 This utility model provides an embodiment of a waterproof LED light source board backplate, comprising a main frame 1, a protective plate 2, and a cover frame 8. The protective plate 2 is fixedly mounted on the upper end of the main frame 1 by screws on both sides. A drainage tube 3 is fixedly mounted on the lower middle part of the protective plate 2. The body of the drainage tube 3 is embedded in the rear end of the main frame 1. A wiring hole 4 is opened at the center of the rear end of the main frame 1. A wiring tube 5 is hinged to the rear end of the wiring hole 4. A rubber tube 6 is sleeved on the body of the wiring tube 5. One end of the rubber tube 6 is fixedly mounted at the wiring hole 4. Specifically, the protective plate 2 has a U-shaped design and is fixed to the upper part of the main frame 1 by screws on both sides. When the protective plate 2 is set on the upper part of the main frame 1, it will cover the gap between the main frame 1 and the cover frame 8, thereby preventing rainwater from entering the main frame 1 through the gap. A drainage pipe 3 is also fixedly installed in the middle of the lower end of the protective plate 2. The upper end of the drainage pipe 3 is open and located in the middle of the upper end of the protective plate 2. The opening is designed to be low-lying. When rainwater falls on the protective plate 2, it will flow towards the low-lying area and enter the drainage pipe 3. Next, the lower end of the drainage pipe 3 is a branch pipe. The rainwater entering the drainage pipe 3 flows downward from the branch pipe, thereby diverting the rainwater away from the rubber pipe 6 and reducing the risk of rainwater directly hitting the rubber pipe 6 and causing leakage. In addition, the wiring hole 4 and the wiring tube 5 provide wiring paths for the backlight module 7. The wiring tube 5 is composed of multiple short tubes that are hinged together. When the worker bends the rubber tube 6, it will cause the multiple short tubes to rotate relative to each other, thus forming a bend. In this way, it provides auxiliary support for the bent rubber tube 6, so that it can still remain in the open-down position after bending, thereby preventing rainwater from entering the main frame 1 from the rubber tube 6.

[0018] Reference Figure 1 - Figure 4A backlight module 7 is provided in the front frame of the main body frame 1. The backlight module 7 includes a backlight source 705. The backlight source 705 is fixedly installed on the inner wall of the rear end of the main body frame 1. A light guide plate 704 is provided at the front end of the backlight source 705. A reflective film 703 is provided at the front end of the light guide plate 704. A diffusion film 702 is fixedly installed at the front end of the reflective film 703. A brightness enhancement film 701 is provided at the front end of the diffusion film 702.

[0019] Specifically, the backlight module 7 is a common light source board in the prior art, which mainly consists of a brightness enhancement film 701, a diffusion film 702, a reflective film 703, a light guide plate 704, and a backlight source 705. Among them, the backlight source 705 is fixedly installed on the inner wall of the rear end of the main frame 1 and faces the side light incident surface of the light guide plate 704; The light guide plate 704 is set at the front end of the backlight source 705 to convert the line light source into a surface light source. The reflective film 703 is set on the back side of the light guide plate 704 to reflect the back light back. The diffuser film 702 is fixedly set at the front end of the reflective film 703 to make the light distribution more uniform. Finally, the brightness enhancement film 701 is placed at the front end of the diffusion film 702 to enhance the brightness of the front light output. Through the above multi-layer design, they work together to achieve a uniform and high-brightness backlight effect.

[0020] Reference Figure 1 - Figure 4 The rear end of the cover frame 8 has a rectangular groove 9, and a sealing gasket 10 is embedded inside the rectangular groove 9. Several evenly distributed holes 11 are opened at the front edge of the main frame 1, and several evenly distributed holes 22 are opened at the edge of the cover frame 8. Screws 13 are threaded inside the holes 11 and holes 22.

[0021] Specifically, a sealing gasket 10 is embedded inside the rectangular groove 9, which matches the shape of the groove. The sealing gasket 10 is made of rubber. When the cover frame 8 is fixed to the main frame 1 by screws 13, the sealing gasket 10 will be compressed between the two, sealing the gaps on the contact surface, thereby preventing external rainwater from seeping into the interior from the connection between the cover frame 8 and the main frame 1.

[0022] Working principle: When rainwater falls, it first drips onto the protective plate 2, then collects at the opening at the top of the drain pipe 3, and then falls into the drain pipe 3. The rainwater will roll down along the drain pipe 3, bypassing the power cord until it is discharged. Then, the staff bends the rubber tube 6 downwards, which drives the cable conduit 5 to bend simultaneously. The cable conduit 5 provides support for the bent rubber tube 6, making its opening face downwards, thereby preventing rainwater from entering through the opening of the rubber tube 6. Secondly, a sealing gasket 10 is embedded inside the rectangular groove 9 at the rear end of the cover frame 8. The workers fix the cover frame 8 at the front end of the main frame 1 by screwing the screw 13 into the hole 11 and the hole 12. When rainwater seeps in from the connection between the cover frame 8 and the main frame 1, it will be blocked by the sealing gasket 10, thus preventing internal water seepage.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
