Technical Field

[0002] Headlights refer to lighting devices installed on both sides of the head of a car for driving on the road at night. There are two-lamp and four-lamp systems. The lighting effect of headlights directly affects the driving operation and traffic safety at night. Therefore, traffic management departments in various countries in the world generally stipulate the lighting standards of automobile headlights in the form of laws to ensure the safety of night driving. With the development and progress of science and technology, headlights have also been upgraded from traditional halogen bulbs or xenon lamps to LED headlights. The brightness of LED is much higher than that of halogen headlights and xenon headlights. LED headlights have a wide illumination range and high brightness, which can greatly improve the vehicle's recognition and improve driving safety.

[0003] When car lights are used for a long time at night in the summer, they will generate high heat. In the hot summer, as the ambient temperature rises, the temperature of the car lights will be higher. Long-term use will damage the bulbs, affecting the normal use of the driver at night. The bulbs will be damaged due to overheating during driving, especially when driving on highways at night, which poses a huge safety hazard. Although existing car lights dissipate heat for the headlights by opening heat dissipation holes, the heat dissipation effect is not ideal, and external dust and water vapor can easily enter the headlights and interfere with internal components. In severe cases, a short circuit may occur, affecting the service life of the headlights. Therefore, an automotive LED headlight body conductive heat dissipation module is proposed to solve the above technical problems. Summary of the Invention

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-3 A car LED headlamp body conductive heat dissipation module includes a lamp holder 1, a heat dissipation mechanism is provided on the lamp holder 1, and a protective mechanism is provided on the lamp holder 1.

[0026] In this embodiment, the heat dissipation mechanism includes mounting blocks 2 fixedly mounted on the front and back of the lamp holder 1. There are four mounting blocks 2, which are fixedly mounted on the outside of the lamp holder 1 in groups of two, making it convenient to install the lamp holder 1 on the car through multiple mounting blocks 2.

[0027] Among them, a lampshade 3 is fixedly installed on the right side of the lamp holder 1, an LED lamp body 4 located inside the lampshade 3 is fixedly installed on the right side of the lamp holder 1, a plurality of temperature sensors 5 are fixedly installed on the right side of the lamp holder 1 and located inside the lampshade 3, two ventilation seats 6 are fixedly installed on the right side of the lamp holder 1, and two sealing mounting grooves are opened on the right side of the lamp holder 1. The ventilation seats 6 are fixedly connected to the lamp holder 1 through the sealing mounting groove, which facilitates the installation of the two ventilation seats 6 through the sealing mounting groove and improves the sealing, thereby discharging the heat generated by the LED lamp body 4.

[0028] Among them, a supply fan 7 is provided inside the bottom ventilation seat 6, an exhaust fan 8 is provided inside the top ventilation seat 6, and a protective net 9 is fixedly installed inside the two ventilation seats 6. An isolation box 10 corresponding to the position of the top ventilation seat 6 is fixedly installed on the right inner wall of the lamp holder 1, and a heat dissipation pipe 11 extending to the top of the lamp holder 1 is fixedly installed on the left side of the top ventilation seat 6.

[0029] Among them, a mounting hole is provided at the top of the lamp holder 1, and the heat dissipation pipe 11 extends to the top of the lamp holder 1 through the mounting hole, so that the heat generated by the LED lamp body 4 can be discharged to the outside of the lamp holder 1 through the heat dissipation pipe 11, thereby improving the stability of the use of the LED lamp body 4. An air inlet pipe 12 is fixedly installed on the left side of the lamp holder 1, and a connecting groove is provided on the left side of the lamp holder 1. The air inlet pipe 12 is fixedly connected to the left side of the lamp holder 1 through the connecting groove, so that the outside air can enter the interior of the lamp holder 1 through the air inlet pipe 12, thereby realizing air circulation, thereby realizing heat dissipation of the LED lamp body 4 and improving its service life.

[0030] In this embodiment, the protective mechanism includes a limit seat 13 fixedly mounted on the inner bottom wall of the lamp holder 1, a sealing sleeve 14 fixedly mounted on the inner top wall of the lamp holder 1, a filter plate 15 is plugged into the top of the limit seat 13, and a moisture-proof plate 16 located on the right side of the filter plate 15 is plugged into the top of the limit seat 13. A docking groove is provided on the top of the limit seat 13, and the position of the docking groove corresponds to the position of the filter plate 15 and the moisture-proof plate 16, so that the preliminary positioning of the filter plate 15 and the moisture-proof plate 16 can be conveniently performed through the docking groove, thereby facilitating subsequent accurate fixed use.

[0031] Among them, a mounting seat 17 is provided on the top of the limit seat 13, and a dust collecting bag 18 is movably plugged into the top of the mounting seat 17. Plug-in slots are provided on the top of the lamp holder 1 and the inside of the sealing sleeve 14. The filter plate 15, moisture-proof plate 16 and dust collecting bag 18 are all installed to the inside of the lamp holder 1 through the plug-in slots, which makes it convenient to install the filter plate 15, moisture-proof plate 16 and dust collecting bag 18 through the plug-in slots, thereby blocking and absorbing dust and moisture in the outside air, and preventing dust or water vapor from entering and interfering with electronic components. A mounting plate 19 is fixedly installed on the top of the filter plate 15 and the moisture-proof plate 16.

[0032] Among them, two fixing blocks 20 are fixedly installed on the top of the lamp holder 1. The interiors of the two fixing blocks 20 are rotatably connected to the limiting screws 21 that are movably engaged with the mounting plate 19. Plug holes are provided on both sides of the mounting plate 19. The limiting screws 21 are movably engaged with the two sides of the mounting plate 19 through the plug holes, which makes it convenient for the limiting screws 21 to fix the installed mounting plate 19 through the plug holes, thereby preventing it from loosening during the driving of the car.

[0033] Among them, a fixing frame 22 is fixedly installed inside the air inlet pipe 12, and a rotating rod 23 is rotatably connected inside the fixing frame 22. A wind blade 24 is fixedly installed on the left side of the rotating rod 23, and a brush plate 25 rotatably connected to the filter plate 15 is fixedly installed on the right side of the rotating rod 23. A rotating hole is opened inside the fixing frame 22, and the rotating rod 23 is rotatably connected to the fixing frame 22 through the rotating hole, so that when the outside air enters the interior of the lamp holder 1, the airflow drives the wind blade 24 and the rotating rod 23 to rotate, thereby driving the brush plate 25 to brush the dust on the filter plate 15, avoiding clogging of the filter plate 15 and affecting the heat dissipation.

[0034] During use, the lamp holder 1 is mounted on the corresponding mounting position of the vehicle via the mounting block 2, and the connecting wires of the internal electronic components are connected to the vehicle power supply. When the LED lamp body 4 is in operation, the vehicle's internal central control system detects a temperature rise via the temperature sensor 5 and activates the exhaust fan 8 and the supply fan 7. The air intake duct 12 then transports outside air into the lampshade 3 to remove heat generated by the LED lamp body 4, and the heat is discharged to the outside of the lamp holder 1 via the heat dissipation pipe 11. This ensures continuous flow of air within the lampshade 3, creating a suitable working environment for the LED lamp body 4 and enabling continuous and stable operation. After the outside air enters the lamp holder 1, the filter plate 15 and the moisture-proof plate 16 remove dust and moisture from the air, thereby protecting the electronic components within the lamp holder 1. Furthermore, the air flow drives the fan blades 24 to rotate, causing the brush plate 25 on the rotating rod 23 to brush dust off the surface of the filter plate 15 and collect it in the dust bag 18. This reduces the frequency of cleaning, and only requires internal cleaning during vehicle maintenance, ensuring the stability of the vehicle lamp during daily use.

[0035] The beneficial effects of the above embodiment are:

[0036] The heat dissipation module of the automobile LED headlamp lamp body, through the provided heat dissipation mechanism, exchanges the heat generated when the LED lamp body 4 is working through the air exchange between the inside and outside of the lamp holder 1, so that the heat is discharged to the outside of the lamp holder 1, so that the internal temperature of the lampshade 3 is suitable for the normal operation of the LED lamp body 4, thereby improving the use stability and extending the service life of the LED lamp body 4, and with the cooperation of the protective mechanism, filtering the dust and water vapor of the air for heat exchange in the lamp holder 1, thereby preventing dust and water vapor from entering the interior of the lamp holder 1 and interfering with the normal operation of electronic components, thereby helping to improve the stability of equipment operation, and brushing and collecting dust through the brush plate 25 and the dust collecting bag 18, thereby avoiding clogging of the filter plate 15, thereby achieving long-lasting heat dissipation inside the lamp holder 1.
