Description

An auto-heating car light fixture Technical Field

[0001] This utility model relates to the field of automotive lighting, specifically an automotive lighting fixture with automatic heat dissipation. Background Technology

[0002] Automotive lights play a vital role in automobiles, providing illumination for nighttime driving and warning signals for other vehicles and pedestrians. Based on their function, automotive lights can be divided into two main categories: headlights and signal lights. They can also be divided into external lights and internal lights based on their installation location.

[0003] With the development of the automotive industry, the functions of automotive lighting are becoming increasingly diversified, especially with the widespread application of new light sources such as LEDs in automotive lighting. Although LED light sources have advantages such as energy saving and long lifespan, they generate a lot of heat during operation. If the heat cannot be dissipated in time, it will cause the internal temperature of the lamp to rise. If the lamp relies solely on the lamp housing for heat dissipation and lacks automatic temperature control, it cannot adjust in time according to changes in the internal temperature of the lamp, which will affect the luminous efficiency, light decay rate and lifespan of the LED light source, and may even cause circuit failures, posing safety hazards. Summary of the Invention

[0004] The purpose of this utility model is to provide an automatic heat dissipation automotive lamp to solve the problems mentioned in the background art and overcome its technical defects.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an automatic heat dissipation automotive lamp, including a housing, a heat dissipation cylinder fixedly connected to the outer surface of the housing, a lamp body fixedly installed inside the housing, a precision temperature sensor fixedly installed on the inner wall of the housing, multiple air guide channels fixedly connected inside the heat dissipation cylinder, a cooling fan fixedly installed inside the heat dissipation cylinder, a protective railing fixedly connected to the outer surface of the heat dissipation cylinder, and an integrated control module fixedly installed on the outer surface of the heat dissipation cylinder.

[0006] As a further embodiment of this utility model: a square box is fixedly connected to the upper surface of the heat sink, the integrated control module is located inside the square box, and a cover plate is installed on the upper surface of the square box.

[0007] As a further improvement of this utility model, a vent is provided on the outer surface of the shell.

[0008] As a further improvement of this utility model: the outer surface of the heat sink is provided with a plurality of ventilation slots, and a protective net is installed inside each ventilation slot.

[0009] As a further improvement of this utility model: multiple heat dissipation fins are fixedly connected to the outer surface of the shell, and each heat dissipation fin is wavy.

[0010] As a further improvement of this utility model, the outer surface of the housing is provided with a plurality of mounting cylinders.

[0012] As a further improvement of this invention: the integrated control module is electrically connected to a precision temperature sensor and a cooling fan via wires.

[0013] Compared with the prior art, the beneficial effects of this utility model include:

[0014] The internal temperature of the lamp is monitored in real time by a precision temperature sensor, and the data is transmitted to the integrated control module. When the temperature exceeds the set threshold, the integrated control module automatically starts the cooling fan, accelerates air circulation through the air guide channel, realizes automatic temperature control and heat dissipation, ensures that the lamp body works at a suitable temperature, extends the lamp body's service life, and improves luminous efficiency.

[0022] An embodiment of the present invention is shown in conjunction with Figures 1-4.

[0023] An automatic heat dissipation automotive lamp includes a housing 2, a heat dissipation cylinder 1 fixedly connected to the outer surface of the housing 2, a lamp body 3 fixedly installed inside the housing 2, a precision temperature sensor 12 fixedly installed on the inner wall of the housing 2, multiple air ducts 13 fixedly connected inside the heat dissipation cylinder 1, a cooling fan 14 fixedly installed inside the heat dissipation cylinder 1, a protective railing 15 fixedly connected to the outer surface of the heat dissipation cylinder 1, and an integrated control module 16 fixedly installed on the outer surface of the heat dissipation cylinder 1. The integrated control module 16 is electrically connected to the precision temperature sensor 12 and the cooling fan 14 via wires. The cooling fan 14 is a silent direct-drive type. The cooling fan has an adjustable speed. The heat sink 1, lamp body 3, precision temperature sensor 12, cooling fan 14 and integrated control module 16 work together to realize automatic heat dissipation and temperature control of the lamp. When the precision temperature sensor 12 detects that the internal temperature of the lamp has reached the set start temperature, it transmits a signal to the integrated control module 16. The integrated control module 16 starts the cooling fan 14. As the internal temperature of the lamp decreases, when the temperature is lower than the set stop temperature, the integrated control module 16 controls the cooling fan 14 to stop running, realizing automatic temperature control and heat dissipation, and ensuring that the lamp works at a suitable temperature.

[0024] In this embodiment, a square box 8 is fixedly connected to the upper surface of the heat sink 1. The integrated control module 16 is located inside the square box 8. A cover plate 9 is installed on the upper surface of the square box 8. The square box 8 provides protection for the integrated control module 16, preventing it from being affected by external factors. The cover plate 9 makes it easy to open the square box 8, facilitating the maintenance, repair, and debugging of the integrated control module 16. A vent 17 is provided on the outer surface of the housing 2, and multiple ventilation slots 6 are provided on the outer surface of the heat sink 1. A protective net 7 is installed inside each ventilation slot 6. When the cooling fan 14 is working, air enters the lamp through the vent 17, exchanges heat with the lamp body 3, and is discharged outside the lamp through the air guide channel 13. The ventilation slots 6 increase the contact area between the heat sink 1 and the outside air, improving the heat dissipation efficiency. The protective net 7 is made of fine mesh to prevent dust, insects, and other foreign objects from entering the lamp through the ventilation slots 6, while not affecting the airflow and protecting the internal structure of the lamp.

[0025] In this embodiment, multiple heat dissipation fins 5 are fixedly connected to the outer surface of the housing 2. Each heat dissipation fin 5 is wavy. Multiple mounting cylinders 4 are provided on the outer surface of the housing 2. A mounting ring 10 with an opening is fixedly connected to the outer surface of the housing 2. A sealing ring 11 is fixedly connected to the inner ring of the mounting ring 10 with an opening. Heat is conducted from the housing 2 to the heat dissipation fins 5. The wavy heat dissipation fins 5 have a larger surface area and can fully contact the outside air to accelerate heat dissipation. The mounting cylinder 4 can be connected to the corresponding mounting point on the car body by bolts or other connectors to ensure that the lamp is firmly installed. The mounting ring 10 with an opening enhances the stability of the lamp installation. The sealing ring 11 ensures the sealing of the lamp and prevents rainwater, dust and other substances from entering the lamp and protects the lamp body 3 and other internal components.

[0026] Working principle: When the automotive lights are working, the lamp body 3 generates heat. The precision temperature sensor 12 monitors the internal temperature of the lamp in real time. When the temperature rises to a certain level, the precision temperature sensor 12 transmits a signal to the integrated control module 16. The integrated control module 16 starts the cooling fan 14. The cooling fan 14 runs, and air flows rapidly through the air guide channel 13, carrying away the heat inside the lamp and achieving automatic heat dissipation. When the cooling fan 14 is working, air enters the lamp from the vent 17, exchanges heat with the lamp body 3, and is then discharged outside the lamp through the air guide channel 13. The wave-shaped heat dissipation fins 5 increase the heat dissipation area, effectively transferring the heat inside the lamp to the outside air, improving the heat dissipation effect, achieving automatic temperature control heat dissipation, and ensuring that the lamp works at a suitable temperature.

[0027] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
