Abstract
Description
Technical Field
[0001] This utility model relates to the field of motorcycle headlight technology, and in particular to an integrated high and low beam LED headlight. Background Technology
[0002] Motorcycle headlights are crucial components for ensuring nighttime driving safety. With the widespread adoption of LED technology, integrated high and low beam LED headlights are increasingly used in motorcycles due to their compact structure, high luminous efficiency, and long lifespan. However, due to the inherent structural characteristics of motorcycles, headlights operate in harsher environments, facing numerous core challenges: inherent flaws in the heat dissipation system design, the limited space in motorcycle headlights, poor heat dissipation, and the frequent spikes in LED junction temperature to the critical high-temperature point, leading to luminous flux attenuation and severely impacting lighting performance and lifespan. Furthermore, motorcycles are frequently exposed to rain, washing, and dust, and motorcycle headlights have weak sealing designs (such as relying on a single sealing ring), making them prone to failure under long-term vibration and thermal shock. To address these issues, a solution is proposed below. Utility Model Content
[0003] The purpose of this invention is to provide an integrated high and low beam LED headlight with the advantages of good heat dissipation and excellent sealing performance.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0005] A high / low beam integrated LED headlight includes a housing. A ring groove is provided on one side of the housing, and several LED daytime running light beads are installed inside the ring groove. A light-transmitting cover is connected to one end of the housing. A detachable heat-conducting base is also provided inside the housing. A reflector is fixed to the inner side of the heat-conducting base, and a heat sink is fixed to the rear end of the heat-conducting base. Several heat dissipation fins are fixed to the inner wall of the heat sink. A heat dissipation mounting base is also fixed to the inner side of the heat dissipation mounting base. An illumination module is fixedly mounted on the heat dissipation mounting base by bolts, and the top of the illumination module is located inside the reflector. Several pin-fin heat sinks are arranged around the heat dissipation mounting base, and a detachable cooling fan is connected to the inner side of the heat dissipation mounting base.
[0006] Preferably, the outer shell has a first contact surface and a second contact surface on one side, and the light-transmitting cover has a first contact block and a second contact block on the inner side. The first contact surface has a first sealing groove, and the first contact block has a first sealing protrusion that is adapted to the first sealing groove. The second contact surface has a second sealing groove, and the second contact block has a second sealing protrusion that is adapted to the second sealing groove.
[0007] Preferably, a plurality of connecting blocks are fixedly provided on the rear side of the housing, and each connecting block is provided with a fixing screw, the top of which is inserted into the heat-conducting base.
[0008] Preferably, the cooling fan is connected to several mounting brackets, and the inner side of the cooling mounting base is fixed with several mounting plates. The mounting brackets are fixedly connected to the mounting plates by bolts.
[0009] Preferably, a protective cover is also fixed to the rear side of the outer shell, and a number of fixing blocks are fixed to the outer side of the protective cover, each of the fixing blocks having a fixing hole.
[0010] Preferably, the top of the heat-conducting base is provided with a limiting protrusion ring, the second contact surface is provided with a limiting groove, and the limiting protrusion ring is located in the limiting groove.
[0011] The beneficial effects of this utility model are as follows:
[0012] 1. When connecting the light-transmitting cover to the housing, simply apply sealant into the first sealing groove and the second sealing groove respectively. Then, the light-transmitting cover can be placed on the housing, so that the first sealing protrusion is embedded in the first sealing groove, and at the same time, the second sealing protrusion is embedded in the second sealing groove. After the sealant cures, the light-transmitting cover and the housing can be fixed together. The cooperation between the first sealing protrusion and the first sealing groove, as well as the second sealing protrusion and the second sealing groove, can effectively increase the accuracy of the connection position between the housing and the light-transmitting cover, and at the same time ensure the sealing performance between the housing and the light-transmitting cover, further improving the overall sealing performance of the headlight.
[0013] 2. The heat-conducting base provides excellent heat conduction, transferring the internal heat of the headlight during use to the heat sink. Several heat sink fins further enhance heat dissipation, and the cooling fan further cools the lighting module. This effectively prevents overheating and reduced lifespan of the headlight. The numerous pin-fin heat sinks also contribute to efficient heat dissipation, resulting in superior overall headlight cooling and facilitating widespread use. Attached Figure Description

[0019] like Figures 1 to 3 As shown, an integrated high and low beam LED headlight includes a housing 1. A ring groove 2 is provided on one side of the housing 1, and a plurality of LED daytime running light beads 3 are installed inside the ring groove 2. A light-transmitting cover 4 is connected to one end of the housing 1, providing daytime illumination through the LED daytime running light beads 3. A first contact surface 13 and a second contact surface 14 are provided on one side of the housing 1. A first contact block 28 and a second contact block 29 are provided inside the light-transmitting cover 4. A first sealing groove 15 is provided on the first contact surface 13, and a first sealing protrusion 16 is provided on the first contact block 28, which is adapted to the first sealing groove 15. A second sealing groove 17 is provided on the second contact surface 14, and a second sealing protrusion 18 is provided on the second contact block 29, which is adapted to the second sealing groove 17. When the light-transmitting cover 4 is connected to the housing 1, sealant is simply applied into the first sealing groove 15. The light-transmitting cover 4 can then be placed on the outer shell 1 within the second sealing groove 17, allowing the first sealing protrusion 16 to be embedded in the first sealing groove 15, while the second sealing protrusion 18 is embedded in the second sealing groove 17. After the adhesive cures, the light-transmitting cover 4 and the outer shell 1 can be fixed together. The cooperation between the first sealing protrusion 16 and the first sealing groove 15, as well as the second sealing protrusion 18 and the second sealing groove 17, can effectively increase the accuracy of the connection position between the outer shell 1 and the light-transmitting cover 4, while ensuring the sealing performance between the outer shell 1 and the light-transmitting cover 4, and further improve the overall sealing performance of the headlight.
[0020] The outer casing 1 also includes a detachable heat-conducting base 5, which is made of aluminum oxide alloy and has excellent thermal conductivity. Several connecting blocks 19 are fixed to the rear side of the outer casing 1. Each connecting block 19 is fitted with a fixing screw 20, the top of which is inserted into the heat-conducting base 5. The fixing screws 20 securely connect the connecting block 19 to the heat-conducting base 5, thus achieving a fixed connection between the outer casing 1 and the heat-conducting base 5. Similarly, quick disassembly between the outer casing 1 and the heat-conducting base 5 is also possible. A limiting protrusion 26 is provided on the top of the heat-conducting base 5, and a limiting groove 27 is provided on the second contact surface 14. The limiting protrusion 26 is located within the limiting groove 27. When the heat-conducting base 5 is installed on the outer casing 1, its outer limiting protrusion 26 is embedded in the limiting groove 27. The second contact block 29 simultaneously presses against the limiting protrusion 26, further improving the stability of the heat-conducting base 5 installation.
[0021] A reflector 6 is fixedly mounted on the inner side of the heat-conducting base 5, and a heat sink 7 is fixedly mounted at the tail end of the heat-conducting base 5. Several heat sink fins 8 are fixedly mounted on the inner wall of the heat sink 7, and a heat sink mounting base 9 is also fixedly mounted on the inner side of the heat sink 7. The lighting module 10 is fixedly mounted on the heat sink mounting base 9 by bolts, and the top of the lighting module 10 is located inside the reflector 6. Several pin-fin heat sinks 11 are arranged around the heat sink mounting base 9, and a detachable cooling fan 12 is connected to the inner side of the heat sink mounting base 9. The internal heat of the headlight during use can be conducted through the heat-conducting base 5, and then the heat can be conducted to the heat sink 7. The several heat sink fins 8 can achieve excellent heat dissipation effect, and the cooling fan 12 can further dissipate heat from the lighting module 10. Therefore, it can effectively prevent the headlight from overheating during use and thus reduce its service life. At the same time, the several pin-fin heat sinks 11 can achieve efficient heat dissipation effect, so the overall heat dissipation effect of the headlight is better, which is conducive to its widespread use. The lighting module 10 is an integrated high and low beam LED lighting lamp containing a lens. Its structure and model are existing technologies, so they will not be described in detail.
[0022] Several mounting brackets 21 are connected to the cooling fan 12. Several mounting plates 22 are fixedly mounted on the inner side of the cooling mounting base 9. The mounting brackets 21 are fixedly connected to the mounting plates 22 by bolts. The bolts allow for the fixing and disassembly of the mounting plates 22, thus enabling quick assembly and disassembly of the cooling fan 12. A protective cover 23 is also fixedly mounted on the rear side of the outer casing 1. Several fixing blocks 24 are fixedly mounted on the outer side of the protective cover 23. Each fixing block 24 has a fixing hole 25. The fixing blocks 24 and fixing holes 25 allow for the fixed connection between the headlight and the motorcycle body.
