Description

Technical Field

[0001] This utility model relates to the technical field of LED street lights, specifically a high-power semiconductor lighting module for LED street lights. Background Technology

[0002] With the development of the times, streetlights have become an indispensable lighting tool for urban nightlife. Streetlights generally need to work for long periods of time, even in severe weather such as storms, rain, and snow. At the same time, with the increasing emphasis on the brightness of streetlights illuminating the ground, high-power LED lighting modules have emerged. However, the higher the LED power, the greater the heat generation. If the heat dissipation capacity is insufficient, the temperature inside the LED light will become too high, which will cause danger, burn out the circuit board or other electronic components, and seriously affect the working life and quality of the high-power LED lighting module.

[0003] Currently, many so-called high-power LED lighting module products have appeared on the market. Most of these products adopt a large-area planar structure to increase the heat dissipation capacity of LED lights, resulting in heavy weight and large volume. When encountering strong winds, rain, or snow, high-power LED lighting modules hanging on high poles either cannot withstand strong winds or snow accumulation, or their large area makes them prone to dust accumulation, thus affecting heat dissipation and performance. Installation is also inconvenient. In addition, many high-power LED lighting modules on the market are simply traditional streetlights with some basic optical treatments, which do not meet the requirements of road lighting at all.

[0004] In conclusion, many existing high-power LED lighting modules are not truly applicable to the road lighting field. Therefore, the market is calling for the emergence of a brand-new high-power LED lighting module product. Utility Model Content

[0005] The purpose of this invention is to provide a high-power semiconductor lighting module for LED streetlights that allows for quick installation and disassembly while ensuring the normal operation of high-power lighting components.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-power semiconductor lighting module for LED streetlights includes an aluminum substrate with an internal circuit. The aluminum substrate has several slots, each containing an LED chip. A mounting plate is detachably connected to the periphery of the aluminum substrate. The end of the mounting plate furthest from the aluminum substrate is mounted inside the streetlight cover. Several heat sink fins are detachably connected inside the mounting plate, and a metal tube is fixed through each fin. A heat-conducting pipe is fixed to the aluminum substrate facing the heat sink fins, and the heat-conducting pipe is detachably connected to the metal tube.

[0008] Furthermore, connecting plates are fixed at both ends of the heat dissipation fins, and fixing plates are welded to the connecting plates facing the inner wall of the mounting plate. One end of the fixing plate is provided with a through groove, and a crossbar is fixed inside the through groove. A support rod is rotatably connected to the outside of the crossbar. An abutment plate is fixed to the end of the support rod away from the crossbar, and the abutment plate is fitted against the inner wall of the mounting plate.

[0009] Furthermore, a torsion spring is sleeved on the outside of the crossbar, with one end of the torsion spring fixed to the inner wall of the through groove and the other end fixed to the side of the support rod.

[0010] By adopting the above technical solution, when the connecting plate is placed inside the mounting plate, the abutment plate that is in contact with the inner wall of the mounting plate slides in along the inner wall of the mounting plate. At the same time as the abutment plate slides in, the abutment plate drives the support rod to rotate. At this time, the torsion spring located outside the crossbar begins to compress, and then the torsion spring has the potential energy of rebound. This potential energy can drive the abutment plate to rotate toward the inner wall side of the mounting plate, thereby making the two connecting plates and the heat dissipation fins between the connecting plates stably clamped and installed inside the mounting plate.

[0011] Furthermore, a connecting pipe is provided between the metal tube and the heat-conducting pipe, the connecting pipe and the metal tube are threaded together, and the connecting pipe and the heat-conducting pipe are plugged together.

[0012] By adopting the above technical solution, after the heat dissipation fins are installed, the connecting pipe is rotated and screwed to both ends of the metal pipe. After the connecting pipe is connected to the metal pipe, it is then inserted and fixed to the heat conduction pipe fixed on the aluminum substrate, thereby stably installing the heat dissipation fins inside the mounting plate.

[0013] Furthermore, an L-shaped connecting plate is screwed onto the aluminum substrate, and the other end of the L-shaped connecting plate is screwed onto the inner wall of the mounting plate. Several L-shaped connecting plates are provided on the aluminum substrate.

[0014] By adopting the above technical solution, the aluminum substrate and the mounting plate are fixed by multiple L-shaped connecting plates, and the mounting plate can be installed quickly.

[0015] Furthermore, the mounting plate has screw insertion holes on its side, and a plurality of screw insertion holes are provided at equal intervals along the edge of the mounting plate.

[0016] By adopting the above technical solution, it is easy to install the mounting plate inside the street light cover.

[0017] In summary, the beneficial technical effects of this utility model are as follows:

[0018] 1. It adopts a mounting plate and heat dissipation fins, so the heat dissipation fins can be selected according to the required power. It has a built-in heat dissipation structure to ensure the normal operation of high-power lighting components, and has a high degree of selectivity.

[0019] 2. A crossbar and abutment plate structure is adopted. When the connecting plate is placed inside the mounting plate, the abutment plate, which is in contact with the inner wall of the mounting plate, slides in along the inner wall of the mounting plate. At the same time as the abutment plate slides in, the abutment plate drives the support rod to rotate. At this time, the torsion spring located outside the crossbar begins to compress, and then the torsion spring has the potential energy of rebound. This potential energy can drive the abutment plate to rotate toward the inner wall of the mounting plate, so that the two connecting plates and the heat dissipation fins between the connecting plates can be stably clamped and installed inside the mounting plate.

[0020] 3. A heat pipe is used. After the heat sink fins are installed, the connecting pipe is screwed to both ends of the metal pipe. After the connecting pipe is connected to the metal pipe, it is then inserted and fixed to the heat pipe fixed on the aluminum substrate. This allows the heat sink fins to be stably installed inside the mounting plate, while also enabling rapid heat conduction and dissipation. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] 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.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a high-power semiconductor lighting module for LED streetlights, comprising an aluminum substrate 1, with an internal circuitry on the aluminum substrate 1, and a plurality of slots 2 on the aluminum substrate 1, each slot 2 having an LED bead 3 inserted inside. A mounting plate 4 is detachably connected to the periphery of the aluminum substrate 1, and the end of the mounting plate 4 away from the aluminum substrate 1 is installed inside the streetlight cover. A plurality of heat dissipation fins 5 are detachably connected inside the mounting plate 4, and a metal tube 6 is fixedly inserted through all the heat dissipation fins 5. A heat-conducting pipe 7 is fixed to the end of the aluminum substrate 1 facing the heat dissipation fins 5, and the heat-conducting pipe 7 is detachably connected to the metal tube 6.

[0030] Among them, the heat dissipation fins 5 are fixed with connecting plates 8 at both ends, and the connecting plates 8 are welded with fixing plates 9 facing the inner wall of the mounting plate 4. One end of the fixing plate 9 is provided with a through groove 10, and a crossbar 11 is fixed inside the through groove 10. A support rod 12 is rotatably connected to the outside of the crossbar 11. An abutment plate 13 is fixed at the end of the support rod 12 away from the crossbar 11. The abutment plate 13 is fitted to the inner wall of the mounting plate 4.

[0031] Meanwhile, a torsion spring 14 is fitted on the outside of the crossbar 11. One end of the torsion spring 14 is fixed to the inner wall of the through groove 10, and the other end is fixed to the side of the support rod 12.

[0032] When the connecting plate 8 is placed inside the mounting plate 4, the abutment plate 13, which is in contact with the inner wall of the mounting plate 4, slides in along the inner wall of the mounting plate 4. As the abutment plate 13 slides in, it drives the support rod 12 to rotate. At this time, the torsion spring 14 located outside the crossbar 11 begins to compress, and the torsion spring 14 has the potential energy of rebound. This potential energy can drive the abutment plate 13 to rotate toward the inner wall of the mounting plate 4, thereby allowing the two connecting plates 8 and the heat dissipation fins 5 between the connecting plates 8 to be stably clamped and installed inside the mounting plate 4.

[0033] Meanwhile, a connecting pipe 15 is provided between the metal pipe 6 and the heat-conducting pipe 7. The connecting pipe 15 is threadedly connected to the metal pipe 6, and the connecting pipe 15 is plugged into the heat-conducting pipe 7.

[0034] After the heat sink fins 5 are installed, the connecting pipe 15 is screwed to both ends of the metal pipe 6. After the connecting pipe 15 is connected to the metal pipe 6, it is then inserted and fixed to the heat conduction pipe 7 fixed on the aluminum substrate 1 through the connecting pipe 15, thereby stably installing the heat sink fins 5 inside the mounting plate 4.

[0035] Furthermore, an L-shaped connecting plate 16 is screwed onto the aluminum substrate 1. The other end of the L-shaped connecting plate 16 is screwed onto the inner wall of the mounting plate 4. Several L-shaped connecting plates 16 are provided on the aluminum substrate 1, and the aluminum substrate 1 and the mounting plate 4 are fixed by multiple L-shaped connecting plates 16.

[0036] Meanwhile, screw insertion holes 17 are provided on the side of the mounting plate 4. Several screw insertion holes 17 are provided at equal intervals along the edge of the mounting plate 4, which makes it easy for the mounting plate 4 to be installed inside the street light cover.

[0037] The working principle of this utility model is as follows: Based on an aluminum substrate 1 containing electrical circuits, multiple LED beads 3 are installed on the aluminum substrate 1. The multiple LED beads 3 are connected in series, so the number of installations can be adjusted. When the number of installations is large, the internal power of the aluminum substrate 1 increases, and the heat dissipation of the aluminum substrate 1 increases. A quick-installation mounting plate 4 is set on the outside of the aluminum substrate. The mounting plate 4 is fixed to the aluminum substrate 1 with screws. At the same time, multiple heat dissipation fins 5 are installed inside the mounting plate 4. The heat dissipation fins 5 dissipate heat through the connection between the metal tube 6 and the heat conduction pipe 7, which can quickly remove the heat on the aluminum substrate 1, so that it can work normally under high power conditions.
