A motorcycle lamp with a heat dissipation structure

Abstract

This utility model discloses a motorcycle lamp with a heat dissipation structure, including a lamp housing, an LED lamp assembly, a reflector, and a lens. The lamp housing consists of a detachable rear housing and a front housing. The reflector and lens are located in the front housing, and the LED lamp assembly is located in the reflector. Addressing the issues of limited space in motorcycle lamp covers and difficulty in heat dissipation for LED lamps, a lamp housing cooling fan is located at the rear end of the rear housing, while a vent and a movable cover are located on the lower front side. The fan's forced airflow and directional air circulation quickly remove heat from the LED lamps, controlling the lamp body temperature and preventing a decrease in luminous efficiency due to high temperatures, thus ensuring stable brightness. The movable cover allows for flexible opening and closing of the vent, balancing heat dissipation efficiency with protection against harsh environments, preventing moisture and dust from entering. This solves the problems of halogen lamps being prone to burnout and LED lamps having poor heat dissipation, improving driving safety.

Description

Technical Field

[0001] This utility model relates to the field of motorcycle lamp technology, and in particular to a motorcycle lamp with a heat dissipation structure. Background Technology

[0002] Currently, halogen lamps are still widely used as the main lighting source in the field of motorcycle lights. However, halogen lamps have inherent defects: they have high power and high energy consumption, and they generate a lot of heat when working. After long-term use, the filament is prone to melting and the lamp body is burned out due to high temperature. The sudden damage of the lamp will directly cut off the driving light, which will bring great safety hazards to motorcycles at night or in complex road conditions.

[0003] To overcome the drawbacks of halogen lamps, LED lamps, with their significant advantages of low power consumption, low energy consumption, and long lifespan, have become an ideal alternative for motorcycle lights. However, motorcycle lamp covers are limited by installation space and vehicle structure, resulting in narrow and compact internal cavities with extremely poor ventilation. This poses a severe challenge to the heat dissipation of LED lamps. The heat generated by LED lamps during operation cannot be effectively dissipated within the confined space, causing the internal temperature of the lamp body to rise continuously. This temperature increase directly affects the luminous efficiency of the LED lamp; the higher the temperature, the lower the luminous efficiency, which in turn reduces the actual brightness of the LED lamp, failing to meet the lighting intensity required for motorcycle operation and thus affecting driving safety. Utility Model Content

[0004] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a motorcycle lamp with a heat dissipation structure.

[0005] The above objective is achieved through the following technical solution:

[0006] A motorcycle lamp with a heat dissipation structure includes a lamp housing, an LED lamp assembly, a reflector, and a lens disposed on the front side of the lamp housing. The lamp housing includes a rear housing and a front housing detachably mounted on the front side of the rear housing. The reflector and lens are disposed on the front housing, and the LED lamp assembly is disposed on the reflector. A lamp housing cooling fan is disposed at the rear end of the rear housing, and a vent and a movable cover are disposed on the lower front end of the rear housing. The movable cover is used to open or close the vent.

[0007] In some embodiments, a slide rail is provided inside the rear housing, and the movable cover plate is slidably disposed within the slide rail.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] 1. Addressing the issues of limited space in motorcycle headlight housings and difficulty in heat dissipation for LED lights, a cooling fan is installed at the rear of the rear housing. This, combined with a vent at the lower front, creates an active heat dissipation channel. The combination of forced draft and directional airflow from the fan quickly removes heat generated by the LED lights within the confined space, effectively controlling the internal temperature of the headlight and preventing a decrease in luminous efficiency due to high temperatures. This ensures the LED lights maintain stable brightness, meeting the lighting needs of motorcycles. Simultaneously, a movable cover allows for flexible opening and closing of the vents, ensuring efficient heat dissipation while preventing moisture and dust from entering in rainy or dusty environments. This prevents fan malfunction and damage to internal components due to moisture, completely resolving the dual problems of halogen lamps being prone to burnout and LED lights having poor heat dissipation, significantly improving driving safety.

[0016] 2. The headlight housing features a detachable design between the rear and front housings, adapting to the limited installation space of motorcycle headlight covers. The components are compactly arranged and flexibly assembled. When maintenance is required, there is no need to disassemble the entire headlight cover; only the front housing needs to be removed, simplifying the maintenance process and reducing costs.

[0022] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0023] like Figures 1-5 As shown, this embodiment provides a motorcycle lamp with a heat dissipation structure, including a lamp housing 1, an LED lamp assembly, a reflector 2 disposed within the lamp housing 1, and a lens 3 disposed on the front side of the lamp housing 1. The lamp housing 1 includes a rear housing 4 and a front housing 5 detachably mounted on the front side of the rear housing 4. The reflector 2 and the lens 3 are disposed on the front housing 5, and the LED lamp assembly is disposed on the reflector 2. A lamp housing cooling fan 6 is disposed at the rear end of the rear housing 4, and a vent 7 and a movable cover 8 are disposed on the lower front end of the rear housing 4. The movable cover 8 is used to open or close the vent 7.

[0024] According to the above structure, the LED light assembly is fixed on the reflector cup 2. After being powered on, the light emitted is reflected and focused by the reflector cup 2, and then refracted by the lens 3 on the front housing 5 of the headlight housing 1 to form a uniform and concentrated lighting beam, thereby realizing the directional lighting function required for motorcycle driving and meeting the driving vision requirements at night or in low light environments.

[0025] The heat generated when the LED light assembly is working is partly conducted to the front housing 5 through the reflector cup 2, and partly dissipated directly into the internal cavity of the headlight housing 1; after the headlight housing cooling fan 6 at the rear end of the rear housing 4 is started, the hot air is exhausted to the outside of the headlight housing 1 through the ventilation port 7 by the headlight housing cooling fan 6.

[0026] The movable cover 8 works in conjunction with the vent 7 to adapt to different working conditions. When the motorcycle is in a sunny or high-speed environment where enhanced heat dissipation is required, the movable cover 8 can be opened to increase the ventilation volume of the vent 7 and improve heat dissipation efficiency. When encountering harsh environments such as rain, sandstorms, or mud, the movable cover 8 can be closed to seal the vent 7, preventing moisture, dust, mud, and other foreign objects from entering the headlight housing 1. This avoids moisture, dust accumulation, or damage to components such as the LED light assembly, headlight housing cooling fan 6, and reflector cup 2, ensuring stable operation of the equipment.

[0027] In addition, the headlight housing 1 adopts a design in which the rear housing 4 and the front housing 5 are detachably connected. When maintenance is required, the fixing structure of the front housing 5 and the rear housing 4 can be removed to remove the front housing 5 separately. There is no need to disassemble the entire headlight housing 1 and the motorcycle's mounting structure, which simplifies the maintenance operation process.

[0028] In this utility model, a sliding rail 21 is provided inside the rear housing 4, and the movable cover plate 8 is slidably disposed in the sliding rail 21. The sliding rail 21 preset inside the rear housing 4 provides a precise installation guide and limiting channel for the movable cover plate 8.

[0029] Furthermore, a handle 31 is provided on the outside of the movable cover plate 8. When it is necessary to adjust the state of the vent 7 according to the working conditions, the user can apply force through the handle 31 on the outside of the movable cover plate 8 to drive the movable cover plate 8 to slide along the slide rail 21, thereby opening or closing the vent 7.

[0030] In this utility model, a fan mounting base 41 is provided on the inner wall of the rear end of the rear housing 4. The lamp housing cooling fan 6 is mounted on the fan mounting base 41. The fan mounting base 41 provides a dedicated mounting reference for the lamp housing cooling fan 6. The lamp housing cooling fan 6 is assembled on the fan mounting base 41 by bolt fixing, ensuring that the relative position of the lamp housing cooling fan 6 and the rear housing 4 is fixed.

[0031] Furthermore, a chuck seat 51 connected to the LED light group is provided at the rear end of the reflector cup 2. The chuck seat 51 at the rear end of the reflector cup 2 and the LED light group form a precise assembly fit. The LED light group is fixed on the chuck seat 51 by means of snap-fit, so that the light-emitting center of the LED light group is precisely aligned with the reflection focus of the reflector cup 2.

[0032] See Figures 2-5As shown, the LED lamp assembly includes a lamp holder body 61, with a mounting cavity inside the lamp holder body 61. A copper substrate 62, a lamp body cooling fan 64, and a PCB board 63 are arranged sequentially in front and behind the mounting cavity. A light-transmitting hole 68 and a ventilation hole 65 communicating with the mounting cavity are respectively provided on the outer side of the lamp holder body 61. An LED lamp bead 66 is disposed on the copper substrate 62 and is disposed in the light-transmitting hole 68. Several ventilation holes 65 are provided, respectively corresponding to one side of the copper substrate 62 and the lamp body cooling fan 64. A chuck 67 connected to a chuck seat 51 is also provided outside the lamp holder body 61, and an electrical connection plug 69 is provided at the rear end.

[0033] The LED light assembly is precisely fixed by the chuck 67 on the outside of the lamp holder 61 and the chuck seat 51 at the rear of the reflector cup 2, ensuring the relative position stability of the lamp holder 61 and the reflector cup 2. The mounting cavity inside the lamp holder 61 provides a layered assembly space for the copper substrate 62, the lamp body cooling fan 64, and the PCB board 63. The LED beads 66 on the copper substrate 62 are embedded in the light-transmitting holes 68 of the lamp holder 61. The PCB board 63 and the electrical connector 69 enable circuit conduction. After power is applied, the light emitted by the LED beads 66 is emitted through the light-transmitting holes 68, and then reflected by the reflector cup 2 and refracted by the lens 3 to form a directional lighting beam, ensuring the accuracy of the lighting.

[0034] When the LED beads 66 are working, the heat generated is first conducted to the copper substrate 62. At the same time, the lamp body cooling fan 64 is activated. Several ventilation holes 65 on the outside of the lamp holder 61, corresponding to the copper substrate 62 and the lamp body cooling fan 64, enter the mounting cavity, flow over the surface of the copper substrate 62 and carry away the heat. After being accelerated by the lamp body cooling fan 64, the hot air is discharged from the lamp holder 61 through the ventilation holes 65 on the other side. This achieves a dual heat dissipation effect of local heat dissipation inside the lamp assembly and overall heat dissipation of the lamp housing, quickly reducing the working temperature of the LED beads 66.

[0035] Of course, the reflector cup 2 and the headlight housing 1 are not completely sealed, allowing airflow.

[0036] Furthermore, the rear end of the copper substrate 62 is provided with an clearance opening 71, and the lamp body cooling fan 64 is disposed within the clearance opening 71. Thus, the clearance opening 71 at the rear end of the copper substrate 62 provides a precise embedded installation space for the lamp body cooling fan 64, which is directly disposed within the clearance opening 71. At the same time, after the lamp body cooling fan 64 is embedded in the clearance opening 71, the distance between it and the copper substrate 62 and the PCB board 63 is greatly reduced. This not only compresses the overall axial space of the LED lamp assembly, but also allows the lamp body cooling fan 64 to directly act on the heat dissipation surface of the copper substrate 62, accelerating the speed at which cold air flows across the surface of the copper substrate 62. Combined with the ventilation holes 65 of the lamp holder body 61, this makes the local heat dissipation airflow circulation more efficient.

[0037] Furthermore, the copper substrate 62 is provided with a plug-in portion 81 at its rear end. The plug-in portion 81 is inserted into the PCB board 63 and electrically connected to the PCB board 63.

[0038] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
