Technical Field
[0001] This utility model relates to the field of automotive lighting equipment, and in particular to an intelligent cooling LED automotive light. Background Technology
[0002] In today's automotive market, automotive lighting technology is constantly advancing. Traditional automotive headlights and interior lighting mainly rely on devices such as halogen lamps and xenon lamps for illumination, but these devices have drawbacks such as high energy consumption, high heat generation, and short lifespan. With rising ambient temperatures and increased driving time, the continuous high temperatures of automotive headlights not only affect their own lifespan but also cause discomfort and safety hazards for passengers. This problem is particularly prominent in hot summers or during long drives. To address these issues, some designs attempting to reduce heat generation have emerged, such as integrating heat sinks and using more efficient bulbs that operate at lower temperatures. However, most of these measures have limited effectiveness and cannot reliably solve the heat dissipation problem of automotive lights during prolonged operation or in high-temperature environments. Utility Model Content

[0016] The present invention will be further described in detail below with reference to the accompanying drawings.
[0017] Example: A smart cooling LED automotive light, such as Figure 1 and Figure 2 As shown, the device includes a headlight body 1, which is equipped with a light-emitting module, a cooling module, a power supply module, and a control module. The light-emitting module is an LED light source integrated board 2 that is fixedly connected to the headlight body 1. When the LED light source integrated board 2 is lit, the control module controls the opening and closing of the cooling module in real time according to the cooling requirements. The cooling module includes an air-cooling component and a liquid-cooling component. The air-cooling and liquid-cooling channels achieve intelligent switching under the combined action of the control module to meet the combined cooling effect under complex cooling requirements.
[0018] The air-cooling component includes a heat dissipation cavity 3 located at the rear of the light-emitting module and a ventilating cavity 4 fixed to the heat dissipation cavity 3. A heat-conducting plate 17 is also connected to the rear of the LED light source integrated board 2, extending into the heat dissipation cavity 3. This efficiently dissipates heat generated by the light-emitting integrated board. Simultaneously, the heat dissipation cavity 3 also promptly ventilates the light and heat generated at the front of the LED headlight to the ventilating cavity 4. A cooling fan 5 is installed inside the ventilating cavity 4, and an exhaust port 6 is located at the rear of the ventilating cavity 4. A heat dissipation fin groove 13 is located on the side of the ventilating cavity 4. A large amount of high-temperature gas is drawn in along the heat dissipation fin groove 13. The cooling fan 5 quickly blows the heat inside the headlight to the outside, achieving localized air cooling and maintaining the normal operating temperature of the LED light source integrated board 2, preventing overheating that could lead to spontaneous combustion or burnt-out LED beads.
[0019] Considering the fluctuations in the internal air-cooling efficiency of automotive lighting products, especially when the ambient temperature is too high, the control module senses when the actual cooling efficiency of the air-cooling component is poor and promptly controls the liquid-cooling component to work synchronously. The liquid-cooling component includes a first liquid-cooling cavity 7 located on the side of the heat dissipation cavity block 3, a second liquid-cooling cavity 8 located at the rear of the air venting cavity block 4, and a heat exchange cavity 9 located between the first liquid-cooling cavity 7 and the second liquid-cooling cavity 8, achieving a rapid heat exchange and transfer process through the liquid cooling medium.
[0020] The heat dissipation cavity 3 has an aluminum alloy wall, which can promptly transfer the heat accumulated in part of the heat dissipation cavity 3 to the coolant in the liquid cooling cavity 7, achieving a cooling effect through heat transfer. The heat exchange cavity 9 is fixed to the side of the air venting cavity 4. When the control module starts the liquid cooling module, a micro pump 10 is installed in the heat exchange cavity 9. The liquid cooling cavity 7 and the liquid cooling cavity 8 are connected by a medium delivery conduit 11. The micro pump 10 can accelerate the real-time flow of the coolant medium between the liquid cooling cavity 7 and the liquid cooling cavity 8, forming a heat transfer. Since the liquid cooling cavity 8 is located at the rear of the air venting cavity 4, the airflow generated by the cooling fan 5 can simultaneously cool the heat in part of the liquid cooling cavity 8, ultimately achieving a cooling effect on the cooling medium in the liquid cooling cavity 8. This forms a combined linkage between the liquid cooling cavity 7 and the liquid cooling cavity 8, realizing heat transfer. The inner wall of the liquid cooling chamber 2 8 is provided with corrugated grooves 16, which increases the contact area of airflow and helps to improve the cooling efficiency of the cooling medium in the liquid cooling chamber 2 8.
[0021] Since liquid cooling effectively compensates for air cooling, a transparent observation window 14 is provided on the surface of the liquid cooling chamber 7 to further enhance the understanding and control of the cooling process. This allows users to periodically check and observe the status of the cooling medium, including the liquid level and the flow rate during operation. If the liquid level is insufficient or the flow rate decreases, the coolant needs to be replaced or replenished in a timely manner. The side of the liquid cooling chamber 7 is equipped with a coolant replacement port 15, which facilitates timely and targeted maintenance by users.
[0022] Considering the compact structural design of the vehicle headlight components and the fact that the exterior of the headlight is the main heat dissipation and ventilation area, the power supply module in this intelligent cooling LED automotive headlight is located on the side of the heat exchange chamber 9 away from the ventilation chamber block 4, adopting a side-mounted structure. The power supply module is equipped with a power quick-connect slot 12, which satisfies the normal power supply while realizing a reasonable layout of the cooling channel, reducing the possible interference to the power supply module, improving the safety factor of the headlight, and ensuring the overall cooling reliability of the headlight.
[0023] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
