Description

Technical Field

[0001] This utility model relates to the field of motorcycle lighting technology, specifically to a novel motorcycle auxiliary light. Background Technology

[0002] Currently, in the motorcycle market, many motorcycle enthusiasts and self-driving tourers install auxiliary lights on their motorcycles to allow drivers to see road conditions more clearly and intuitively. However, traditional auxiliary lights only provide simple illumination and cannot adjust the light according to actual conditions. Therefore, in order to control the auxiliary headlights according to actual road conditions while riding a motorcycle, LED integrated high and low beam lens modules are used to enable users to drive more safely in different road conditions.

[0003] Currently, most motorcycle auxiliary lights on the market place the most frequently used main light assembly (usually low beam) in the center of the light body, while the less frequently used auxiliary light assembly (usually high beam) is arranged around the main light assembly to achieve the best lighting effect. Furthermore, to improve the working stability of the auxiliary lights, the light body is usually made of a metal material with a high heat dissipation coefficient, ensuring that the light assembly can transfer heat to the outside air through the light body. However, in practical applications, the inventors have found that since the light body mainly relies on its exterior contact with the air for heat conduction, and the main light assembly, located in the center, is far from the outer edge of the light body, the heat transfer path is longer, resulting in relatively poor heat dissipation for the main light assembly. After prolonged operation, the operating temperature of the main light assembly will be relatively high, which will not only affect the lifespan of the main light assembly but may also affect the lighting effect. Secondly, due to the layout design of the circuit wires in the center of the light body, it is difficult for the main light assembly, also located in the center, to form effective contact with the light body, further affecting the heat dissipation effect of the main light assembly. To address this problem, this utility model proposes a novel motorcycle auxiliary light. Summary of the Invention

[0004] This invention provides a novel auxiliary light for motorcycles to solve the problems mentioned in the background section.

[0005] The objective of this utility model is achieved through the following means:

[0006] A novel motorcycle auxiliary light includes a metal housing and a light source module disposed within the metal housing. A light-transmitting lampshade assembly is disposed on one side of the metal housing. The light source module includes a first lamp group and a second lamp group. The second lamp group is mounted around the first lamp group on the inner wall of the metal housing. A heat dissipation backplate is mounted on the side of the metal housing away from the lampshade assembly, and the first lamp group is mounted on the heat dissipation backplate.

[0007] Furthermore, the first lamp group includes a main lamp bead and a main circuit board, the main circuit board being provided with a first light-emitting element corresponding to the main lamp bead, and the main circuit board being mounted on the heat dissipation backplate; the second lamp group includes a sub-circuit board and at least two sub-lamp beads, the main circuit board being provided with a second light-emitting element corresponding to the sub-lamp beads, and the sub-circuit board being mounted on the inner wall of the metal casing.

[0008] Furthermore, the light source module also includes a fixing plate for fixing the main lamp bead and the auxiliary lamp bead, the main lamp bead being arranged at the center of the fixing plate, and the auxiliary lamp bead being mounted around the main lamp bead on the fixing plate.

[0009] Furthermore, the metal housing is provided with a sidewall extending toward the center of the metal housing, and a platform for mounting the second lamp assembly is provided on the side of the sidewall near the lampshade assembly.

[0010] Furthermore, the outer side of the metal casing is provided with multiple through-type heat dissipation ducts.

[0011] Furthermore, the heat dissipation backplate has a plurality of outwardly protruding heat-conducting columns evenly arranged on the side away from the first lamp group.

[0012] Furthermore, the heat dissipation backplate is fixedly installed on the side of the metal housing away from the lampshade assembly by screws, and a sealing ring is provided between the heat dissipation backplate and the metal housing.

[0013] Furthermore, the lampshade assembly includes a cover plate and a light-transmitting cover, wherein the cover plate securely mounts the light-transmitting cover to one side of the metal housing.

[0014] Furthermore, a rotatable fixing bracket is installed on the metal casing, and the fixing bracket is provided with screw holes and / or screw slots.

[0015] Furthermore, the wire is disposed on the heat dissipation backplate, and the center of the wire is offset from the center of the metal casing.

[0016] The structural design of this utility model effectively solves the problem of poor heat dissipation in existing motorcycle auxiliary lights. Specifically, the beneficial effects of this utility model are mainly reflected in the following:

[0017] First, this invention utilizes a heat dissipation backplate and a metal casing to dissipate heat from the first and second lamp groups respectively. This partitioned heat dissipation layout achieves efficient heat dissipation for both lamp groups, significantly shortening the heat dissipation path of the first lamp group without affecting the heat dissipation of the second lamp group, thus improving heat dissipation efficiency. Second, the lamp module still places the most frequently used first lamp group in the center of the lamp body, while the less frequently used second lamp group is arranged around the periphery of the first lamp group, ensuring optimal lighting effect. This design allows both lamp groups to maintain a low temperature during prolonged operation, effectively extending their lifespan and ensuring lighting performance. Attached Figure Description

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] In this embodiment, refer to Figure 1 - Figure 6A novel auxiliary motorcycle light, specifically implemented therein, includes a metal housing 3 and a light source module disposed within the metal housing 3. A light-transmitting lampshade assembly is disposed on one side of the metal housing 3. The light source module includes a first lamp group 1 and a second lamp group 2. The second lamp group 2 is mounted around the first lamp group 1 on the inner wall of the metal housing 3. A heat dissipation backplate 4 is mounted on the side of the metal housing 3 away from the lampshade assembly. The first lamp group 1 is mounted on the heat dissipation backplate 4.

[0027] like Figure 6 As shown, in this embodiment, the first lamp group 1 includes a main lamp bead 101 and a main circuit board 102. The main circuit board 102 is provided with a first light-emitting element 103 corresponding to the main lamp bead 101. The main circuit board 102 is mounted on the heat dissipation backplate 4. The second lamp group 2 includes a sub-circuit board 201 and eight sub-lamp beads 202. The main circuit board 102 is provided with eight second light-emitting elements 203 respectively corresponding to the sub-lamp beads 202. The sub-circuit board 201 is mounted on the inner wall of the metal casing 3. By directly mounting the main circuit board 102 and the sub-circuit board 201 on the heat dissipation backplate 4 and the metal casing 3 respectively, the heat dissipation path of the first light-emitting element 103 and the second light-emitting element 203 can be effectively shortened, improving the heat dissipation efficiency of the lamp group and extending the service life of the lamp group.

[0028] In this embodiment, eight auxiliary LED beads 202 are arranged around one main LED bead 101 within the metal casing 3. The main LED bead 101 is a low beam LED, and the eight auxiliary LED beads 202 are arranged alternately as four floodlight high beam LEDs and four spotlight high beam LEDs. This ensures that when the motorcycle is driving at night or in low-light conditions, it can provide sufficient low beam illumination while also achieving a longer field of vision through the high beam LEDs, thus enhancing driving safety. Both the heat dissipation backplate 4 and the metal casing 3 are made of high thermal conductivity materials, such as aluminum alloy, to further accelerate heat transfer and dissipation.

[0029] Furthermore, the lamp source module also includes a fixing plate 5 for fixing the main lamp bead 101 and the auxiliary lamp bead 202. The main lamp bead 101 is installed at the center of the fixing plate 5, and the auxiliary lamp bead 202 is installed around the main lamp bead 101 on the fixing plate 5. The fixing plate 5 is fixed inside the metal housing 3 with screws, and the auxiliary lamp bead 202 is fixedly covered on the sub-circuit board 201. The bottom of the auxiliary lamp bead 202 is also provided with a positioning post for fitting and cooperating with the sub-circuit board 201. The main lamp bead 101 is fixedly installed on the fixing plate 5 with screws, thereby fixing the main lamp bead 101 and the auxiliary lamp bead 202. The fixing plate 5 is provided with light-transmitting holes corresponding to the positions of the main lamp bead 101 and the auxiliary lamp bead 202. The function of the fixing plate 5 is to stably fix the main lamp bead 101 and the auxiliary lamp bead 202 inside the metal housing 3 to prevent them from loosening.

[0030] like Figure 5 As shown, the metal housing 3 has a sidewall 301 extending towards its center. A platform 302 for mounting the second lamp assembly is located on the side of the sidewall 301 near the lampshade assembly. By aligning the bottom plane of the sub-circuit board 201 with the plane of the platform 302, sufficient contact area is ensured, preventing any impact on heat dissipation efficiency. Furthermore, to ensure the stability of the contact between the two planes, thermally conductive silicone grease can be filled between the sub-circuit board 201 and the platform 302. In practical applications, the heat generated by the second lamp assembly 2 is directly conducted to the outer circumference of the metal housing 3 through the sidewall 301. This structure has a short heat conduction path and high heat dissipation efficiency, thereby achieving external heat dissipation through the outer surface of the metal housing 3.

[0031] Furthermore, the outer side of the metal casing 3 is surrounded by multiple through-type heat dissipation ducts 303. The design of the heat dissipation ducts 303 helps to quickly dissipate heat from the metal casing 3, further enhancing the heat dissipation effect. Each heat dissipation duct 303 is elongated and evenly distributed along the circumference of the metal casing 3, ensuring that heat can be evenly dissipated and avoiding local overheating. The openings of the heat dissipation ducts 303 face the side of the metal casing 3 closest to the lamp cover assembly, and carry away heat through natural convection, thereby keeping the operating temperature of the lamp source module within a reasonable range.

[0032] like Figure 2As shown, the heat dissipation backplate 4 has multiple outwardly protruding heat-conducting pillars 401 evenly arranged on the side away from the first lamp group 1. The design of the heat-conducting pillars 401 further increases the heat dissipation area of ​​the heat dissipation backplate 4 and improves the heat dissipation efficiency. These heat-conducting pillars 401 can effectively conduct the heat generated by the first lamp group 1 to the external environment through the heat dissipation backplate 4, ensuring optimal heat dissipation performance and structural strength. In practical applications, the air convection between the heat-conducting pillars 401 and the external environment can quickly remove heat, reduce the operating temperature of the lamp source module, and extend its service life.

[0033] Furthermore, the heat dissipation backplate 4 is fixedly installed on the side of the metal housing 3 away from the lampshade assembly by screws. The heat dissipation backplate 4 is detachable to facilitate maintenance and replacement of the first lamp group 1 on the heat dissipation backplate 4. The detachable design of the heat dissipation backplate 4 not only improves the maintainability of the product but also facilitates users to upgrade or adjust the lamp source module according to actual needs. A sealing ring 6 is provided between the heat dissipation backplate 4 and the metal housing 3 to ensure good sealing performance at the connection between the two, preventing moisture or dust and other impurities from entering the interior of the metal housing 3 and damaging the lamp source module. In addition, the design of the sealing ring 6 also improves the waterproof and dustproof rating of the product, making it more suitable for harsh outdoor environments.

[0034] The lampshade assembly includes a cover plate 7 and a light-transmitting cover 8. The cover plate 7 securely mounts the light-transmitting cover 8 to one side of the metal housing 3. The light-transmitting cover 8 is made of a highly transparent material, such as transparent polycarbonate, to ensure that the light emitted by the lamp source module can fully penetrate, providing a bright lighting effect. The cover plate 7 and the metal housing 3 are fixedly connected by screws to ensure structural stability while facilitating disassembly and replacement.

[0035] Furthermore, a rotatable mounting bracket 9 is installed on the metal housing 3. The mounting bracket 9 is provided with screw holes and / or screw slots, allowing the user to adjust the angle and position of the light source module according to actual needs to ensure optimal lighting performance. The design of the mounting bracket 9 not only improves the product's flexibility but also facilitates the installation and adjustment of the motorcycle auxiliary lights in different environments. In practice, the user simply needs to fix the auxiliary light to the motorcycle using the mounting bracket 9 to achieve the installation of the motorcycle auxiliary lights. In addition, the rotating design of the mounting bracket 9 allows for adjustment of the angle of the light source module at any time according to the motorcycle's driving direction and lighting requirements.

[0036] Furthermore, the wire 10 is disposed on the heat dissipation backplate 4, and the center of the wire 10 is offset from the center of the metal housing 3, thereby avoiding the first light-emitting element 103, so that the position of the main circuit board 102 corresponding to the first light-emitting element 103 can be directly attached to the heat dissipation backplate 4, thus avoiding affecting the heat dissipation efficiency of the first lamp group 1.

[0037] One end of the wire 10 is connected to the main circuit board 102 and the sub-circuit board 201, while the other end passes through the heat dissipation backplate 4 and is connected to an external power source to provide power to the entire lamp source module. The arrangement of the wire 10 is carefully designed to ensure that it can meet the power transmission requirements without adversely affecting the heat dissipation of the lamp source module.

[0038] The structural design of this utility model effectively solves the problem of poor heat dissipation in existing motorcycle auxiliary lights. Specifically, the beneficial effects of this utility model are mainly reflected in the following:

[0039] First, this invention utilizes a heat dissipation backplate 4 and a metal casing 3 to dissipate heat from the first lamp group 1 and the second lamp group 2, respectively. This partitioned heat dissipation layout achieves efficient heat dissipation for both lamp groups, significantly shortening the heat dissipation path of the first lamp group 1 without affecting the heat dissipation of the second lamp group 2, thus improving heat dissipation efficiency. Second, the light source module still places the most frequently used first lamp group 1 at the center of the lamp body, while the less frequently used second lamp group 2 is arranged around the periphery of the first lamp group 1, ensuring optimal lighting effect. This design allows both lamp groups to maintain a low temperature during prolonged operation, effectively extending their service life and ensuring lighting performance.

[0040] This invention significantly shortens the heat dissipation path of the main lamp assembly and improves heat dissipation efficiency by mounting the first lamp assembly 1 on the heat dissipation backplate 4 and utilizing the heat-conducting columns 401 on the heat dissipation backplate 4 to conduct heat to the outside of the metal casing 3. This design allows the main lamp assembly to maintain a lower temperature during operation, thereby extending its service life and ensuring lighting performance.

[0041] Secondly, the sealing ring 6 between the heat dissipation backplate 4 and the metal casing 3 effectively prevents moisture, dust, and other impurities from entering the lamp body, ensuring the normal operation of the lamp assembly. Meanwhile, the heat dissipation backplate 4 is fixed to the metal casing 3 with screws; this installation method is not only stable and reliable but also facilitates later maintenance and replacement.

[0042] Furthermore, in this invention, the second lamp group 2 is mounted around the first lamp group 1 on the inner wall of the metal casing 3. This layout not only achieves optimal lighting effect but also allows the auxiliary lamp group to fully utilize the heat dissipation area of ​​the metal casing 3 for heat dissipation. In addition, multiple through-type heat dissipation ducts 303 arranged around the outer side of the metal casing 3 further improve heat dissipation efficiency, enabling the entire lamp body to maintain a low temperature during operation.

[0043] Finally, the lampshade assembly of this utility model includes a cover plate 7 and a light-transmitting cover 8. This design not only ensures the light transmission effect but also makes the overall appearance of the lamp body more beautiful and elegant. At the same time, the rotatable fixing bracket 9 installed on the metal shell 3 allows the user to adjust the angle of the lamp body according to actual needs, thereby achieving a more flexible lighting effect.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
