Technical Field

[0001] The utility model relates to the technical field of LED driving power supplies, in particular to an LED driving power supply with a protection structure. Background Art

[0002] LED driver power supply is a power converter that converts power supply into a specific voltage and current to drive LED to emit light. Usually, the input of LED driver power supply includes high-voltage industrial frequency AC, low-voltage DC, high-voltage DC, low-voltage high-frequency AC, etc. However, there are still some problems with the existing LED driver power supply;

[0003] When existing LEDs are used outdoors, they are prone to surges when encountering thunderstorms. The LED's ability to resist surges is relatively poor, which causes damage to the LED and greatly reduces its service life. The LED driver power supply is required to have a surge protection function. The surge protector absorbs energy to protect the LED lamp, which greatly reduces its own lifespan and requires a high frequency of replacement when damaged. The LEDs that are convenient to disassemble are easy to loosen and fall off, while those that are fixed and stable are difficult to disassemble, making installation and disassembly very inconvenient. To this end, we propose an LED driver power supply with a protective structure. Utility Model Content

By setting a surge protector, in thunderstorm weather, when encountering a surge caused by a lightning strike, the sudden huge energy can be effectively absorbed to protect the LED from damage, thereby greatly improving the service life of the LED. Since the surge protector absorbs energy instead of the LED, its own service life is greatly shortened. The disassembly and installation operation is simple, and it is easy to replace. While the disassembly and installation are portable, the structure is stable to avoid loosening and falling off.

[0019] Embodiment:

[0020] like Figure 1-Figure 3 As shown, an LED driving power supply with a protective structure includes a power supply 1, a mounting groove 18 is provided inside the power supply 1, a surge protector 2 is arranged on one side of the power supply 1, one end of the surge protector 2 is located inside the mounting groove 18, an inner groove 15 is provided inside the surge protector 2, a card groove 17 is provided on the inner wall of the mounting groove 18, a plug rod 7 is arranged inside the inner groove 15, a slider 8 is provided on the top of one side of the plug rod 7, a card block 10 is provided on the top of the slider 8, the top of the card block 10 is located inside the card groove 17, a first spring 9 is provided at the connection between the slider 8 and the card block 10, and the bottom end of the plug rod 7 A limiting groove 16 is provided, a limiting block 14 is provided inside the inner groove 15, the top of the limiting block 14 is inside the limiting groove 16, a second spring 13 is provided at the bottom of the limiting block 14, a support block 12 is provided at the bottom of the second spring 13, a card plate 3 is provided inside the surge protector 2, a convex block 11 is provided at the top of the card plate 3, and the bottom of the support block 12 is in contact with the top of the convex block 11; a first rotating shaft 4 is fixedly connected to the connection between the card plate 3 and the inner wall of the surge protector 2, a release alloy sheet 5 is provided at the middle bottom of the card plate 3, and a tension spring 6 is fixedly connected to the bottom of one side of the surge protector 2;

[0021] When the existing LED is used outdoors, it is easy to generate surges when encountering thunderstorms. The ability of LED to resist surges is relatively poor, which causes damage to the LED and greatly reduces its service life. The LED driving power supply needs to have a surge protection function. The surge protector absorbs energy to protect the LED lamp, which greatly reduces its own service life. The frequency of replacement is high when it is damaged. The convenient disassembly is easy to loosen and fall off, and the fixed and stable ones are difficult to disassemble. The installation and disassembly are very inconvenient. By setting a surge protector 2, when installing, align the surge protector 2 with the installation slot 18 and insert it. The installation slot 18 will squeeze the card block 10, and the first spring 9 will be forced to shrink until the surge protector 2 terminal is inserted into the inner side of the interface of the power supply 1, and the card block 10 reaches the card slot 17 The first spring 9 pushes a part of the top of the card block 10 into the inner side of the card slot 17, and then the insertion rod 7 is inserted into the inner side of the inner slot 15, and the insertion rod 7 pushes the limit block 14 to slide downward on the inner side of the inner slot 15. Since the convex block 11 at the top of the card plate 3 presses against the support block 12 and cannot slide downward, the second spring 13 is forced to contract, and the insertion rod 7 continues to slide forward, and the insertion rod 7 touches the bottom end of the slider 8. The inclined surface of the insertion rod 7 pushes the slider 8 to slide upward on the inner side of the inner slot 15, and the slider 8 pushes the first spring 9 and the card block 10 to move upward. After the card block 10 touches the inner wall of the card slot 17, it cannot move upward. The insertion rod 7 continues to advance, and the first spring 9 is forced to contract until the limit slot 16 of the insertion rod 7 reaches the position above the limit block 14. The second spring 13 in the compressed state pushes the limit block 14 into the inner side of the limit groove 16 to complete the installation; when the surge protector 2 ages, the leakage current of the varistor inside the surge protector 2 gradually increases and generates heat, and the heat causes the leakage current to increase, resulting in the melting and separation of the connection of the tripping alloy sheet 5, and the bottom end of the card plate 3 loses support. The tension spring 6 pulls the card plate 3 to rotate clockwise around the first rotating shaft 4, and the convex block 11 at the bottom end of the card plate 3 no longer resists the support block 12. Under the action of gravity, the support block 12 slides down, and the limit block 14 also leaves the limit groove 16, releasing the lock on the plug rod 7. The plug rod 7 is no longer restricted, and the plug rod 7 is pulled out from the inside of the inner groove 15. The first spring 9 in the compressed state pushes the slider 8 to fall back to At the bottom of the inner groove 15, the surge protector 2 is pulled, and a part of the top of the card block 10 is still inside the card block 10. When the surge protector 2 slides inside the installation groove 18, the card block 10 will be squeezed into the inside of the inner groove 15 until the surge protector 2 is completely pulled out from the inside of the inner groove 15, and a new surge protector 2 is replaced to complete the operation; by setting the surge protector 2, in thunderstorm weather, when encountering a surge caused by lightning strike, it can effectively absorb the sudden huge energy to protect the LED from damage, greatly improving the service life of the LED. Since the surge protector 2 absorbs energy instead of the LED, its own life is greatly reduced. The disassembly and installation operation is simple, easy to replace, and the disassembly and installation are portable, and its structure is stable to avoid loosening and falling off.

[0022] In other embodiments, the present embodiment discloses, please Figure 1As shown, a groove is provided at the top of the power supply 1, a hook 19 is provided at the top of the power supply 1, the bottom end of the hook 19 is located inside the groove, and a second rotating shaft 20 is fixedly connected to the connection between the hook 19 and the inner wall of the groove;

[0023] Select two points at the installation position and screw on the screws. After rotating halfway, hang the hook 19 on the screws, then tighten the screws completely, and then screw the screws into the holes in other directions of the power supply 1 to fix it, and the installation is completed. By setting the hook 19, it can be hung on the screws and then tightened. It is not necessary to hold the power supply 1 with your hands all the time to install it. When there is a slight deviation in the selected point position, the second shaft 20 allows the hook 19 to rotate, and it can be hung on the screw by adjusting the angle. There is no need to unscrew the screws again to find the position again, which saves time and effort and improves work efficiency.

[0024] In other embodiments, the present embodiment discloses, please Figure 1 As shown, a red indicator block is fixedly connected to the inner side of the surge protector 2, a green prompt block is arranged on one side of the red indicator block, and the green prompt block is fixedly connected to one side of the top of the card board 3; by setting a red indicator block fixedly connected to the inner side of the surge protector 2, a green prompt block is arranged on one side of the red indicator block, and the green prompt block is fixedly connected to one side of the top of the card board 3, the green prompt block shows that the surge protector 2 is still working normally, and when the tripping alloy sheet 5 is disconnected, the green prompt block descends with the tripping alloy sheet 5 and no longer blocks the red indicator block, exposing the red indicator block to indicate that the surge protector 2 cannot be used any more and the surge protector 2 needs to be replaced.

[0025] In other embodiments, the present embodiment discloses, please Figure 1 As shown, a square hole is provided on one side of the surge protector 2; by providing a square hole on one side of the surge protector 2, it is convenient to observe whether it is a red indicator block or a green prompt block.
