[0004] When the existing LED car light heat dissipation assembly is working, the heat of the LED car light is transferred to the base. The base increases the heat dissipation area through the heat dissipation fins, and drives the airflow to flow through the fan, thereby dissipating the heat of the LED car light.

Therefore, we propose a heat dissipation assembly for LED car lights to solve the above problems. Utility Model Content

[0017] By adopting the technical solution provided by the utility model, compared with the prior art, the heat dissipation component of the LED lamp of the utility model has the following specific contents:

[0018] (1) A first air guide cover and a second air guide cover are put on the outer side of the lamp holder. When the LED lamp is dissipated, the LED lamp transfers heat to the lamp holder. The lamp holder increases the heat dissipation area through the heat dissipation fins. At the same time, the heat dissipation fan works, driving the air flow from the air inlet into the first air guide cover and the second air guide cover, and then discharges from the air outlet. The first air guide cover and the second air guide cover can guide the air flow generated by the heat dissipation fan, so that the heat dissipation air flow passes through the heat dissipation fins evenly, and the heat dissipation fins and the flowing air are heat exchanged, thereby dissipating the LED lamp.

At the same time, the thermally conductive copper plug-in plate is closely contacted with the inner wall of the slot through the thermally conductive adhesive, which effectively improves the heat transfer efficiency between the thermally conductive copper plug-in plate and the lamp holder. The heat generated by the LED lamp can be quickly transferred to the lamp holder through the copper substrate, the thermally conductive copper plug-in plate, and the thermally conductive adhesive, which can further improve the heat dissipation effect of the LED lamp.

When the inner wall of the insertion hole abuts against the curved surface of the blocking rod, the blocking rod overcomes the elastic force of the spring and retracts into the blocking rod groove. After the plug rod at the blocking rod completely penetrates the insertion hole, the spring pops out the blocking rod. The blocking rod and the second connecting frame abut against both sides of the first connecting frame respectively, so that the first air deflector and the second air deflector can be fixedly connected. At the same time, the first air deflector and the second air deflector are limited by the card slot, so that the first air deflector and the second air deflector can be installed on the outside of the lamp holder. When disassembly is required, pinch the blocking rods on both sides of the plug rod to retract the blocking rod into the blocking rod groove, so that the blocking rod can be moved out of the insertion hole, and the disassembly of the first air deflector and the second air deflector can be completed.

When the first air guide cover 11 and the second air guide cover 12 are installed, the first air guide cover 11 and the second air guide cover 12 are respectively sleeved on both sides of the lamp holder 1, so that the top of the first air guide cover 11 and the second air guide cover 12 are clamped. In the card slot 10, the second connecting frame 14 drives the insertion rod 16 to be inserted into the insertion hole 15. When the inner wall of the insertion hole 15 abuts against the curved surface of the blocking rod 19, the blocking rod 19 overcomes the elastic force of the spring 18 and retracts into the blocking rod groove 17. After the insertion rod 16 at the blocking rod 19 completely penetrates the insertion hole 15, the spring 18 pops out the blocking rod 19, and the blocking rod 19 and the second connecting frame 14 respectively abut against the two sides of the first connecting frame 13, so that the first air guide cover 11 and the second air guide cover 12 can be fixedly connected.

[0036] Working principle: When using the heat dissipation component of the LED lamp, Figures 1 to 4 As shown, first, the first air guide cover 11 and the second air guide cover 12 are put on the outer side of the lamp holder 1. When the LED lamp is cooled, the LED lamp transfers heat to the lamp holder 1. The lamp holder 1 increases the heat dissipation area through the heat dissipation fins 8. At the same time, the heat dissipation fan 9 works to drive the air flow from the air inlet 20 into the first air guide cover 11 and the second air guide cover 12, and then discharges from the air outlet 21. The first air guide cover 11 and the second air guide cover 12 can guide the air flow generated by the heat dissipation fan 9, so that the heat dissipation air flow passes through the heat dissipation fins 8 evenly, and the heat dissipation fins 8 exchange heat with the flowing air, thereby cooling the LED lamp.

When the copper substrate 3 is installed, the heat-conducting copper plug-in plate 5 is inserted into the slot 2, and then the heat-conducting glue is injected into the slot 2 through the heat-conducting glue injection groove 6. After the heat-conducting glue solidifies, the lamp holder 1 can be fixedly connected with the heat-conducting copper plug-in plate 5. At the same time, the heat-conducting copper plug-in plate 5 is closely contacted with the inner wall of the slot 2 through the heat-conducting glue, effectively improving the heat transfer efficiency between the heat-conducting copper plug-in plate 5 and the lamp holder 1, so that the heat generated by the LED lamp can be quickly dissipated through the copper substrate 3, the heat-conducting copper plug-in plate 5, and the heat-conducting glue. The heat dissipation effect of the LED lamp can be further improved by transferring the heat dissipation to the lamp holder 1. When installing the first air deflector 11 and the second air deflector 12, the first air deflector 11 and the second air deflector 12 are respectively sleeved on both sides of the lamp holder 1, so that the tops of the first air deflector 11 and the second air deflector 12 are stuck in the card slot 10. At the same time, the second connecting frame 14 drives the insertion rod 16 to be inserted into the insertion hole 15. When the inner wall of the insertion hole 15 abuts against the curved surface of the blocking rod 19, the blocking rod 19 overcomes the elastic force of the spring 18 and retracts into the blocking rod groove 17. After the insertion rod 16 at the blocking rod 19 completely penetrates the insertion hole 15, the spring 18 pops out the blocking rod 19. The blocking rod 19 and the second connecting frame 14 respectively abut against the curved surface of the blocking rod 19. By holding both sides of the first connecting frame 13, the first air deflector 11 and the second air deflector 12 can be fixedly connected. At the same time, the first air deflector 11 and the second air deflector 12 are limited by the card slot 10, so that the first air deflector 11 and the second air deflector 12 can be installed on the outside of the lamp holder 1. When disassembly is required, pinch the blocking rods 19 on both sides of the insertion rod 16 to retract the blocking rods 19 into the blocking rod grooves 17, so that the blocking rods 19 can be moved out of the insertion hole 15, and the disassembly of the first air deflector 11 and the second air deflector 12 can be completed. Through the quick disassembly and assembly mechanism, the first air deflector 11 and the second air deflector 12 can be quickly installed or disassembled, thereby completing a series of work.
