Description

Technical Field

[0001] This utility model relates to the field of lighting driving technology, specifically a modular LED lighting driving device. Background Technology

[0002] Driven by global green development and energy conservation and emission reduction policies, LED lighting, with its core advantages of low power consumption, long lifespan, and environmental friendliness, has comprehensively replaced traditional incandescent lamps, fluorescent lamps, and other lighting fixtures, becoming the mainstream choice in the global lighting market. Unlike traditional lighting fixtures, LED chips are semiconductor light-emitting devices and cannot be directly connected to the AC mains power grid. They must be driven by a dedicated driver to convert AC to DC and regulate voltage and current to achieve constant current drive, ensuring the stability of light emission and the lifespan of the chips. However, most existing LED drivers adopt an integrated design, containing a large number of rectification, power conversion, and control components. This means that if one component fails, the entire lighting driver becomes unusable and is scrapped. At the same time, the integrated architecture deeply binds the driver to specific lamp models. Lamps with different power and color temperatures have vastly different requirements for driving parameters, resulting in a lack of universality in lighting driver devices. Furthermore, maintenance and replacement require disconnecting and reconnecting the wires and lamp wiring, which can easily lead to wiring errors and short circuits, making use and maintenance extremely inconvenient. Utility Model Content

[0003] The purpose of this utility model is to provide a modular LED lighting driver to solve the problems of inconvenient installation, disassembly and maintenance and lack of versatility of the lighting driver mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a modular LED lighting driver device, comprising a base plate, a waterproof housing fixedly mounted on the outer surface of the base plate, and a circuit board disposed on the inner side of the waterproof housing, wherein the circuit board is not in contact with the outer surface of the base plate and the waterproof housing; a fixing plate is snapped onto the outer surface of the base plate away from the waterproof housing; metal springs are uniformly fixedly welded to the side of the circuit board near the fixing plate; a connecting wire is embedded in the end of the fixing plate near the metal spring, and the outer surface of the connecting wire is in contact with the metal spring; the fixing plate is fixed to the mounting surface by screws; the metal springs pass through the base plate; and a plug-in engagement mechanism is provided between the base plate and the fixing plate.

[0005] Preferably, the insertion and engagement mechanism includes: an insertion block, the insertion block being fixedly disposed on one side of the base plate, the insertion block engaging with a fixed plate, a buckle being fixedly installed at the end of the fixed plate away from the insertion block, and the buckle engaging with the base plate, and a sealing ring being fixedly disposed on the outer surface of the fixed plate, and the outer surface of the sealing ring being tightly fitted with the outer surface of the base plate.

[0006] By adopting the above technical solution, the gap between the inserted base plate and the fixed plate can be sealed by the sealing ring. The base plate and waterproof housing can be quickly and completely removed by snapping the buckle, so that the lighting drive device will not be short-circuited by liquid. It is also convenient to quickly remove and maintain the lighting drive device when it is damaged, without having to unscrew the screws.

[0007] Preferably, copper claw spring terminals are uniformly fixedly welded to the outer surface of the circuit board, and electronic module components are inserted and installed inside the copper claw spring terminals. The outer surface of the electronic module components is in contact with the outer surface of the circuit board, and the top surface of the electronic module components is in contact with the outer surface of the base plate.

[0008] By adopting the above technical solution, some replaceable or damaged electronic module parts can be replaced and maintained through copper claw spring terminals, which greatly reduces the overall scrap caused by the damage of a single electronic module part during use. It also allows for flexible replacement of electronic module parts of corresponding specifications according to the needs of the lighting fixture, which greatly improves versatility, ease of maintenance and reduces the cost of use.

[0009] Preferably, the interior of the waterproof housing is covered with insulating paper, and the two sides of the insulating paper are attached to the side surfaces of the electronic module components. A thermally conductive insulating pad is attached to the side of the circuit board away from the electronic module components, and the outer surface of the thermally conductive insulating pad is attached to the outer surface of the base plate.

[0010] By adopting the above technical solution, the unevenness caused by the copper claw spring terminals on the circuit board can be effectively eliminated by the thermally conductive insulating pad, and the copper claw spring terminals can be prevented from contacting the base plate to avoid leakage. The thermally conductive insulating pad can also conduct heat to the base plate for heat dissipation, ensuring that the circuit board is placed and installed flat while reducing the phenomenon of short circuit leakage.

[0011] Preferably, the base plate and the outer surface of the thermally conductive insulating pad are uniformly provided with insulating through holes, and the insulating through holes are in contact with the outer surface of the metal spring sheet. One end of the metal spring sheet is located outside the base plate, and the fixing plate is recessed on the side near the connecting wire.

[0012] By adopting the above technical solution, the probability of electric shock caused by contact with connecting wires during misoperation can be reduced. At the same time, the metal spring can be insulated through the insulating through hole, so that the base plate and waterproof shell will not come into contact with the metal spring and cause a short circuit.

[0013] Preferably, a waterproof cover is fixedly installed at the end of the fixing plate away from the buckle, and an inlet end and an outlet end are inserted and fixed on the side surface of the waterproof cover. A wire clamping terminal is fixedly installed inside the fixing plate, and the wire clamping terminal is connected to the inlet end and the outlet end respectively. The wire clamping terminal is connected to the connecting wire.

[0014] By adopting the above technical solution, the installation of the power input and output terminals during the installation of the lighting driver is greatly facilitated by the wire crimping terminal. The wire can be fixed by simply inserting it into the wire crimping terminal, and the gap between the power input and output terminals and the waterproof cover can be insulated to reduce short circuits caused by liquid ingress.

[0015] Preferably, a heat-conducting pad is embedded inside the fixing plate, and the outer surface of the heat-conducting pad is in contact with the outer surface of the base plate. Heat dissipation ribs are uniformly fixed on the outer surface of the waterproof shell.

[0016] By adopting the above technical solution, the heat generated by the circuit board and electronic module components during use can be conducted to the outer surface of the base plate and waterproof housing through the thermal pad, allowing the waterproof housing to dissipate heat through the heat dissipation fins, and the heat from the base plate can be conducted to the installed object through the thermal pad, which greatly reduces the damage and failure of electronic module components caused by overheating during the use of the lighting driver device.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This modular LED lighting driver device: 1. When inspecting and maintaining the lighting drive device, simply press the buckle to disengage it from the base plate, allowing the plug block at one end of the base plate to disengage from the fixing plate. This enables the connecting wires and metal springs to be disconnected immediately without disassembling the wiring, greatly improving the convenience and efficiency of disassembling and maintaining the lighting drive device, and reducing the risk of electric shock caused by improper operation during wiring. 2. When connecting LED lights of different sizes and wattages, or when the lighting driver is damaged and unusable, simply remove the base plate from the fixing plate and the waterproof housing from the base plate. Then, the damaged or replaced electronic module parts can be removed from the circuit board, and the electronic module parts that match the specifications of the lamp or are the same can be inserted back into the copper claw spring terminals. This allows for quick and convenient repair of the lighting driver without scrapping the entire device. At the same time, by replacing the electronic module parts of different specifications, it can be adapted to the lamps to be used, which greatly reduces the cost of use and improves versatility. 3. The compression during the fixing of the base plate and the waterproof housing firmly secures the electronic module components to the outer surface of the circuit board, preventing them from moving around inside the waterproof housing and causing poor contact with the copper claw spring terminals. At the same time, the thermally conductive insulating pad conducts and insulates the heat generated during operation, ensuring the stability of the circuit board after placement. This allows the heat generated by the lighting driver to be conducted to the base plate and the waterproof housing, and then dissipated into the air and the mounting object through the thermally conductive pad and heat dissipation fins. This reduces the probability of damage and poor contact of the electronic module components while ensuring the heat dissipation of the lighting driver. Attached Figure Description

[0021] Please see Figures 1-6This utility model provides a technical solution: a modular LED lighting driver device, including a base plate 1, a waterproof housing 2 fixedly mounted on the outer surface of the base plate 1, and a circuit board 3 disposed on the inner side of the waterproof housing 2, wherein the circuit board 3 is not attached to the outer surface of the base plate 1 and the waterproof housing 2. A fixing plate 9 is snapped onto the outer surface of the base plate 1 away from the waterproof housing 2. Metal springs 18 are uniformly fixedly welded to the side of the circuit board 3 near the fixing plate 9. A connecting wire 17 is embedded in the end of the fixing plate 9 near the metal springs 18, and the connecting wire 17 is... The surface is in contact with the metal spring 18, and the fixing plate 9 is fixed to the mounting surface by screws. The metal spring 18 passes through the base plate 1. A plug-in engagement mechanism is provided between the base plate 1 and the fixing plate 9.

[0022] Firstly, when the lighting driver is damaged and requires maintenance, simply press the buckle 12 to disengage from the base plate 1. Then, pinch the waterproof housing 2 and pull it out to disengage the plug block 11 from the fixing plate 9. This allows the base plate 1 and waterproof housing 2 to be quickly removed from the fixing plate 9, enabling the connecting wire 17 and metal spring 18 to be quickly disconnected without rewiring or disconnecting. After that, the base plate 1 and waterproof housing 2 can be disassembled for maintenance, repair, or replacement of parts. The use of the insulating through hole 8 insulates the metal spring 18. After the installation and maintenance are completed, the base plate 1 is inserted back into the fixing plate 9 and fixed. The sealing ring 10 improves the sealing performance after installation. This eliminates the need to spend a long time disassembling the lighting driver in an unsafe environment, greatly improving the convenience of installing, disassembling, and maintaining the lighting driver.

[0023] Copper claw spring terminals 4 are uniformly fixedly soldered on the outer surface of the circuit board 3, and electronic module components 5 are inserted and installed inside the copper claw spring terminals 4. The outer surface of the electronic module components 5 is in contact with the outer surface of the circuit board 3, and the top surface of the electronic module components 5 is in contact with the outer surface of the base plate 1. Insulating paper 6 is attached to the inside of the waterproof housing 2, and the two sides of the insulating paper 6 are in contact with the side surface of the electronic module components 5. A thermally conductive insulating pad 7 is attached to the side of the circuit board 3 away from the electronic module components 5, and the outer surface of the thermally conductive insulating pad 7 is in contact with the outer surface of the base plate 1. Insulating through holes 8 are uniformly opened on the outer surfaces of the base plate 1 and the thermally conductive insulating pad 7, and the insulating through holes 8 are in contact with the outer surface of the metal spring 18. One end of the metal spring 18 is located outside the base plate 1. The side of the fixing plate 9 near the connecting wire 17 is recessed.

[0024] Secondly, after removing the base plate 1 and waterproof housing 2 from the fixing plate 9, and removing the waterproof housing 2 from the base plate 1, the circuit board 3 can be exposed. Then, according to the needs or inspection, damaged or non-compliant electronic module parts 5 can be replaced. The old electronic module parts 5 are pulled out, and the new electronic module parts 5 are inserted into the corresponding copper claw spring terminals 4. Then, the insulating paper 6 and waterproof housing 2 are snapped back and installed and fixed. The corresponding electronic module parts 5 can be replaced according to the usage requirements of the lamp to adapt to the use of different LED lamps, which greatly improves the convenience and versatility of the lighting drive device in use and maintenance.

[0026] Furthermore, when installing the lighting driver, simply fix the fixing plate 9 to the mounting surface with screws, then pass the power input terminal 14 and the output terminal 15 through and fix them to the side of the waterproof cover 13. Then insert the power input terminal 14 and the output terminal 15 into the crimp terminal 16 and press them tightly. Then fix the waterproof cover 13 to the outer surface of the fixing plate 9, which facilitates quick connection and installation of the circuit. After that, simply take out the waterproof housing 2 and insert the plug block 11 into the fixing plate 9 and press it down so that the base plate 1 can be snapped into the buckle 12. After the lighting driver is running, the heat is directed to the base plate 1 and the waterproof housing 2 through the thermally conductive insulating pad 7, so that the heat can be dissipated outward through the heat dissipation fins 20 and conducted into the installed object through the thermally conductive pad 19. Once the power input terminal 14 and the output terminal 15 are installed, they do not need to be moved again, which greatly improves the heat dissipation of the lighting driver during use.

[0027] Working principle: After installation and use for a period of time, if maintenance is required, simply press the buckle 12 and pull down the waterproof housing 2 to remove the plug block 11 from the fixing plate 9. Then, the base plate 1 and the waterproof housing 2 can be disassembled, the circuit board 3 can be removed, and the electronic module component 5 can be pulled out for inspection and replacement. This also makes it easier to inspect damaged electronic module components 5. After that, a new electronic module component 5 can be taken and inserted into the corresponding copper claw spring terminal 4. Different power electronic module components 5 can be replaced to adapt to different LED lights. Then, the circuit board 3 and insulating paper 6 can be reset and placed into the waterproof housing 2. Then, the waterproof housing 2 and the base plate 1 can be snapped together and reinstalled. Then, the plug block 11 can be reinserted into the fixing plate 9 and pressed down to make the buckle 12 snap back into the base plate 1, so that the connecting wire 17 and the metal spring 18 can be connected to complete the inspection, maintenance and replacement of the lighting drive device.
