Description

Technical Field

[0001] This utility model relates to the field of panel light backplate technology, specifically a panel light backplate that is protected against short circuits. Background Technology

[0002] A light backplate is a back panel structure used for light-emitting devices. It is usually made of light-transmitting materials such as acrylic and PS, and is mainly used for light-emitting backplates in LED light boxes, display cabinets, and cabinets. Acrylic light guide plate: Made of acrylic material, it has high light transmittance and is often used in ceiling lights, fan lights and other home lighting fixtures. PS light guide plate: Made of polystyrene, it has a lower cost and is suitable for outdoor billboards, shelf lighting and other scenarios. Luxury stone light guide plate: Made of high-transmittance acrylic or luxury stone material, it is suitable for high-end display cabinets, wine cabinets and other scenarios, and has the characteristics of high brightness and uniform light emission.

[0003] The existing panel light backplates lack insulation material. When the wires and LEDs inside the panel light backplate are detached from the solder joints, or when the surface of the wires is damaged, the metal backplate can easily come into direct contact with the circuit, causing a short circuit and posing a safety hazard.

[0004] Therefore, a short-circuit-proof panel light backplate is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a short-circuit resistant panel light backplate, which can solve the problem that metal backplates are prone to direct contact with circuits, leading to short circuits and posing a safety hazard.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A short-circuit resistant panel light backplate in this embodiment includes a panel light backplate body. A first cavity is formed in the inner wall of the panel light backplate body. A first heat dissipation mesh is fixedly installed inside the panel light backplate body. A second heat dissipation mesh is fixedly installed inside the panel light backplate body. A through hole separates the first and second heat dissipation meshes. All through holes penetrate the left and right side walls of the panel light backplate body. Multiple mounting plates are fixedly installed on the inner wall of the panel light backplate body. Two arc-shaped plates are fixedly installed on the surface of each mounting plate. A spring is fixedly installed on the opposite side of each of the two arc-shaped plates. A first insulating pad is fixedly installed at the end of the spring facing away from the arc-shaped plate. The arc-shaped outer surface of the first insulating pad abuts against the inner wall of the arc-shaped plate.

[0007] Preferably, a second insulating pad is fixedly installed on the front side of the back panel body of the panel light, and the second insulating pad is made of silicone material.

[0008] Preferably, an aluminum alloy substrate is fixedly installed on the side of the second insulating pad away from the back panel body of the panel light, and the second insulating pad and the aluminum alloy substrate are fixed together with high-temperature adhesive.

[0009] Preferably, both the first and second heat dissipation meshes have heat dissipation holes of mm in diameter, and the heat dissipation holes are coated with a polyimide insulating coating.

[0010] Preferably, a second cavity is formed inside the first insulating pad, and the inner wall of the first insulating pad is sleeved on the surface of the spring.

[0011] Preferably, the first heat dissipation mesh and the second heat dissipation mesh are connected from left to right, and the size of the second heat dissipation mesh is two-thirds that of the first heat dissipation mesh.

[0012] Preferably, the contact surface between the first insulating pad and the mounting plate is in a sliding connection, and the material of the first insulating pad is polyurethane elastomer.

[0013] Compared with the prior art, this utility model provides a short-circuit resistant panel light backplate, which has the following beneficial effects:

[0014] 1. The inner wall of the first insulating pad not only protects the surface of the wires, but also, through the polyurethane elastomer material, effectively isolates metal-to-metal contact between electrons, prevents short circuits, and ensures the safe operation of the equipment. In addition, the elastic properties can stably clamp the wires, improving the stability of the LED beads within the panel backplate body.

[0015] 2. By installing both the first and second heat dissipation meshes inside the back panel of the panel light, the back panel of the panel light is protected from dust. At the same time, the polyimide insulating coating sprayed on the surface forms a dense, high-temperature resistant insulating barrier that directly blocks current leakage and short circuits.

[0021] 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.

[0022] Example:

[0023] Please see Figure 1 - Figure 4 In this embodiment, a short-circuit-proof panel light backplate includes a panel light backplate body 1. A first cavity 13 is formed in the inner wall of the panel light backplate body 1. A first heat dissipation mesh 6 and a second heat dissipation mesh 7 are fixedly installed in the panel light backplate body 1. A through hole 4 separates the first heat dissipation mesh 6 and the second heat dissipation mesh 7. The through hole 4 penetrates the left and right side walls of the panel light backplate body 1. Multiple mounting plates 8 are fixedly installed in the inner wall of the panel light backplate body 1. Two arc-shaped plates 9 are fixedly installed on the surface of each mounting plate 8. A spring 11 is fixedly installed on the opposite side of the two arc-shaped plates 9. A first insulating pad 10 is fixedly installed at the end of the spring 11 away from the arc-shaped plate 9. The arc-shaped outer surface of the first insulating pad 10 abuts against the inner wall of the arc-shaped plate 9.

[0024] Through the first heat dissipation mesh 6 and the second heat dissipation mesh 7, air circulation is achieved within the panel light backplate body 1, while also providing dual dust interception. This not only dissipates heat within the panel light backplate body 1 but also prevents dust from entering and causing short circuits. Simultaneously, the polyimide insulating coating 5 forms a dense, high-temperature resistant insulating barrier on the surfaces of the first heat dissipation mesh 6 and the second heat dissipation mesh 7, directly blocking current leakage and short circuits. Furthermore, the first heat dissipation mesh 6 is larger than the second heat dissipation mesh 7, so when the airflow enters the through hole 4 and is discharged into the panel light backplate body 1, it can compress the air, resulting in stronger airflow and better heat dissipation when the airflow is discharged into the panel light backplate body 1.

[0025] Among them, a second insulating pad 2 is fixedly installed on the front of the back panel body 1 of the panel light, and the second insulating pad 2 is made of silicone material;

[0026] The second insulating pad 2 can increase the sealing between the aluminum alloy substrate 3 and the panel light backplate body 1, preventing dust from entering the panel light backplate body 1.

[0027] Among them, an aluminum alloy substrate 3 is fixedly installed on the side of the second insulating pad 2 away from the back panel body 1 of the panel light, and the second insulating pad 2 and the aluminum alloy substrate 3 are fixed with high temperature glue.

[0028] The first heat dissipation mesh 6 and the second heat dissipation mesh 7 are both provided with 3mm heat dissipation holes, and the heat dissipation holes are coated with a polyimide insulating coating 5.

[0029] The first insulating pad 10 has a second cavity inside, and the inner wall of the first insulating pad 10 is sleeved on the surface of the spring 11.

[0030] By setting the spring 11, when the inner wall of the first protective insulating pad is in contact with the surface of the wire, the spring 11 can use its own elasticity to control the first insulating pad 10 to abut against the surface of the wire, thereby achieving the positioning and installation of the wire.

[0031] The first heat dissipation mesh 6 and the second heat dissipation mesh 7 are connected from left to right, and the size of the second heat dissipation mesh 7 is two-thirds that of the first heat dissipation mesh 6.

[0032] The first insulating pad 10 and the mounting plate 8 are in a sliding connection, and the first insulating pad 10 is made of polyurethane elastomer.

[0033] The working principle of the above embodiments is as follows:

[0034] When in use, firstly, the array of LED beads that needs to be placed into the back panel body 1 of the panel light is placed inside the back panel body 1 through the first cavity 13;

[0035] The wires on the lamp bead are inserted into the inner wall of the first insulating pad 10, and the spring 11 can use its elasticity to control the first insulating pad 10 to slide on the surface of the mounting plate 8.

[0036] The inner wall of the first insulating pad 10 is attached to the surface of the wire and installed against it. The lamp bead is placed between the mounting plates 8. While completing the installation and positioning of the lamp bead, the first insulating pad 10 is made of polyurethane elastomer material, which can effectively isolate metal contact between electrons.

[0037] It can also prevent short circuits and ensure the safe operation of the equipment. In addition, it can stabilize the wires through its elastic properties, thereby improving the stability of the LED beads in the panel backplate body 1.

[0038] Since the joint surface between the panel light backplate body 1 and the aluminum alloy substrate 3 is installed with the second insulating pad 2 and fixed with high temperature glue, a reliable and stable structure is formed. At the same time, it can prevent external dust from entering the panel light backplate body 1 and causing a short circuit.

[0039] Meanwhile, the elastic shell of the second insulating pad 2 can buffer the stress generated by the aluminum alloy substrate 3 during vibration, impact or thermal expansion and contraction, and protect the aluminum alloy substrate 3 and components from damage. Through the first heat dissipation mesh 6 and the second heat dissipation mesh 7, it can force or assist air circulation.

[0040] The heat inside the back panel body 1 of the panel light is quickly discharged to prevent heat accumulation from causing overheating inside the back panel body 1 and melting and breaking of the internal insulation material, thereby preventing short circuits in exposed parts. The surface is coated with a polyimide insulating coating 5, which forms a dense, high-temperature resistant insulating barrier on the surface of the first heat dissipation mesh 6 and the second heat dissipation mesh 7, directly blocking current leakage and short circuits. The first heat dissipation mesh 6 and the second heat dissipation mesh 7 are set on one side to intercept dust in a double layer.

[0041] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
