Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to an LED headlight high beam module. Background Technology

[0002] In the field of modern automotive lighting, the performance of LED headlight high beam modules is crucial. With the rapid development of the automotive industry, higher demands are being placed on the brightness, energy consumption, and reliability of vehicle lighting systems. As a new type of lighting source, LEDs, due to their advantages such as high brightness, low energy consumption, and long lifespan, are gradually becoming the mainstream choice for automotive headlight high beam modules.

[0003] Most existing LED headlight high beam modules use a combination of traditional optical lenses and reflectors to focus and project light, and drive LED chips to emit light through circuitry. Their mechanical structure mainly revolves around how to securely mount the LED chips and adapt the optical components. The underlying technology focuses on using optical principles to shape and direct the light emitted by the LEDs to meet lighting needs under different road conditions.

[0004] In existing LED headlight high beam modules, the heat generated by the LED light source mainly relies on the natural conduction of the metal heat sink. During the conduction process, the thermal resistance is relatively large, causing a large amount of heat to accumulate near the LED light source. This prevents the heat from being quickly and effectively transferred to more distant heat dissipation parts, resulting in excessively high operating temperatures of the LED light source. This not only reduces luminous efficiency but also accelerates the aging of the LED chip, affecting the overall performance and lifespan of the LED headlight high beam module. Therefore, an LED headlight high beam module is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an LED headlight high beam module, which aims to improve the problem in the prior art that the heat dissipation cannot be quickly and effectively transferred to distant heat dissipation parts, resulting in excessively high operating temperature of the LED light source, reduced luminous efficiency, and affecting the overall performance and service life of the LED headlight high beam module.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An LED headlight high beam module includes a housing, a rear cover provided on the side wall of the housing, a convex lens provided inside the housing, an inner lens provided on the side wall of the convex lens, an LED light source provided on the side wall of the inner lens, a heat dissipation component provided inside the rear cover, and a fixing component provided on the side wall of the housing.

[0008] The heat dissipation assembly includes a fan, the sidewall of which is fixedly connected to the inside of the rear cover. A protective cover is fixedly connected to the sidewall of the rear cover. A heat-conducting sheet is fixedly connected to the inside of the rear cover. The sidewall of the heat-conducting sheet is attached to the back of the LED light source. Heat dissipation fins are fixedly connected to the inside of the rear cover. A heat pipe is provided on the back of the heat-conducting sheet. A mounting cylinder is fixedly connected to the inside of the rear cover. Multiple air holes are opened on the sidewall of the mounting cylinder. A horizontal plate is fixedly connected to the inside of the mounting cylinder.

[0009] As a further description of the above technical solution:

[0010] The fixing component includes a positioning block and a magnetic block. The sidewall of the positioning block is fixedly connected to the sidewall of the outer shell, and the sidewall of the magnetic block is fixedly connected to the inside of the positioning block.

[0011] As a further description of the above technical solution:

[0012] The evaporation section of the heat pipe is fixedly connected inside the heat-conducting plate, and the condensation section of the heat pipe is fixedly connected inside the heat dissipation fins.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this invention, the heat generated by the LED light source is absorbed and conducted to the heat pipe via a heat-conducting sheet. The heat is then transferred to the heat sink fins for heat dissipation. Simultaneously, a fan is activated, and the resulting airflow is expelled through the gaps in the horizontal plate and the vents, enhancing airflow through the rear cover and further improving heat dissipation. This addresses the problem in some LED headlight high beam modules where heat generated by the LED light source relies on natural conduction through the metal heat sink, leading to a large accumulation of heat near the LED light source, which cannot be quickly and effectively transferred to more distant heat dissipation areas. This causes the LED light source to operate at excessively high temperatures, reducing luminous efficiency and affecting the overall performance and lifespan of the LED headlight high beam module. The above-mentioned structure improves the heat dissipation effect of the device.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 This utility model provides an embodiment of an LED headlight high beam module, comprising a housing 1, a rear cover 2 disposed on the side wall of the housing 1, a convex lens 3 disposed inside the housing 1, an inner lens 4 disposed on the side wall of the convex lens 3, an LED light source 5 disposed on the side wall of the inner lens 4, a heat dissipation assembly disposed inside the rear cover 2, and a fixing assembly disposed on the side wall of the housing 1; the heat dissipation assembly includes a fan 6, the side wall of the fan 6 is fixedly connected to the inside of the rear cover 2, a protective cover 7 is fixedly connected to the side wall of the rear cover 2, a heat-conducting sheet 11 is fixedly connected inside the rear cover 2, the side wall of the heat-conducting sheet 11 is attached to the back of the LED light source 5, a heat dissipation fin 13 is fixedly connected inside the rear cover 2, a heat pipe 12 is disposed on the back of the heat-conducting sheet 11, an installation cylinder 8 is fixedly connected inside the rear cover 2, a plurality of air holes 10 are opened on the side wall of the installation cylinder 8, a horizontal plate 9 is fixedly connected inside the installation cylinder 8, the evaporation section of the heat pipe 12 is fixedly connected to the inside of the heat-conducting sheet 11, and the condensation section of the heat pipe 12 is fixedly connected to the inside of the heat dissipation fin 13;

[0035] When the device is in operation, the LED light source 5 emits light. The light first undergoes preliminary light adjustment and focusing through the inner lens 4. Then, the light is projected onto the convex lens 3, which further converges and refracts the light, focusing the light that has undergone preliminary processing by the inner lens 4 into a beam that meets the requirements of high beam illumination. Finally, it is emitted from the housing 1, providing clear illumination for a long distance in front of the vehicle. The LED light source 5 generates a lot of heat during operation. The heat-conducting plate 11 is attached to the back of the LED light source 5. It is made of copper, which has good thermal conductivity and can quickly absorb the heat generated by the LED light source 5. Based on the principle of heat conduction, heat is transferred from the LED light source 5 to the heat-conducting plate 11, drawing the heat out from the light source. The evaporation section of the heat pipe 12 is connected to the heat-conducting plate 11, allowing the heat absorbed by the heat-conducting plate 11 to be conducted to the evaporation section of the heat pipe 12. In the evaporation section of the heat pipe 12, the working fluid inside absorbs heat and undergoes a phase change, changing from a liquid to a gaseous state. The heat pipe 12 utilizes this gas-liquid phase change characteristic of the working fluid for heat transfer. Due to factors such as the pressure difference between the evaporation and condensation sections, the gaseous working fluid in the heat pipe 12 rises to the condensation section. The condensation section of the heat pipe 12 is fixed to the evaporator... Inside the heat sink 13, the gaseous working fluid transfers heat to the heat sink 13 and then condenses back into a liquid state. The liquid working fluid then flows back to the evaporation section through the capillary structure inside the heat pipe 12 or by gravity. This cycle repeats continuously, transferring heat from the LED light source 5 to the heat sink 13. The heat sink 13 has a large surface area to increase the contact area with the surrounding air, accelerating natural convection heat dissipation. Heat can be quickly dissipated into the surrounding air, reducing the overall temperature. Simultaneously, the fan 6 generates airflow when it starts. The mounting cylinder 8 acts as an airflow guiding component, with multiple openings on its sidewall... The air vents 10 and the internally fixed horizontal plate 9 work together to guide and distribute the airflow generated by the fan 6. Part of the airflow is blown out through the multiple air vents 10 opened on the side wall of the mounting cylinder 8, while another part of the airflow is blown out through the gaps in the internal horizontal plate 9 of the mounting cylinder 8. These blown airflows enhance the airflow near the back cover 2 and accelerate the air renewal around the heat dissipation fins 13. Fresh air can quickly remove the heat emitted by the heat dissipation fins 13, forming a good convection heat dissipation environment, further improving the heat dissipation effect, ensuring that the LED light source 5 is always at a suitable operating temperature, and maintaining its stable and efficient luminous performance.

[0036] Reference Figures 4-5The fixing component includes a positioning block 14 and a magnetic block 15. The side wall of the positioning block 14 is fixedly connected to the side wall of the outer shell 1, and the side wall of the magnetic block 15 is fixedly connected to the inside of the positioning block 14. A fixing sleeve 16 is fixedly connected to the side wall of the outer shell 1. A slider 17 is slidably connected inside the fixing sleeve 16. A slider 20 is fixedly connected to the side wall of slider 17. The side wall of slider 20 is slidably connected inside the fixing sleeve 16. A spring 18 is provided inside the fixing sleeve 16. One end of the spring 18 is fixedly connected to the inside of the fixing sleeve 16, and the other end of the spring 18 is fixedly connected to the lower surface of slider 17. A locking block 19 is fixedly connected to the upper surface of the side wall of slider 17. The side wall of locking block 19 is slidably connected inside the fixing sleeve 16. A pulling block 21 is fixedly connected to the side wall of slider 17. The side wall of pulling block 21 is slidably connected inside the fixing sleeve 16.

[0037] When installing the LED headlight high beam module, when it approaches the corresponding installation position on the vehicle, the magnetic block 15, due to its own magnetism, can attract the corresponding magnetic block 15 on the vehicle's installation location, initially adhering the entire module to that position. This greatly improves the convenience of installation and reduces the time and difficulty of finding the accurate position during installation. Simultaneously, corresponding locking holes are pre-drilled at the vehicle's installation position. As the magnetic block 15 slides into the installation position, when the locking block 19 contacts the edge of the locking hole, it is compressed. This compressive force is transmitted to the spring 18 through the slider 17. Under the action of the compressive force, the spring 18 undergoes compression deformation, storing elastic potential energy. As the magnetic block 15 continues to slide in, when the locking block 19 aligns with the locking hole, the elastic potential energy stored in the spring 18 is released. The resulting elastic force pushes the slider 17 and the locking block 19 to move, causing the locking block 19 to... 9 can be inserted into the corresponding slot, which further fixes the module in the vehicle installation position, enhances the stability of the module installation, and ensures that the module will not loosen or shift due to vibration or other factors during vehicle operation. When the LED headlight high beam module needs to be replaced or repaired, by pulling the pull block 21, the slider 17 slides in the fixing sleeve 16. The sliding of the slider 17 causes the locking block 19 to move with it, while squeezing the spring 18. The spring 18 is compressed and deformed again. As the slider 17 moves, the locking block 19 gradually disengages from the corresponding slot, releasing the fixing effect between the module and the vehicle installation position. At this time, because the magnetic attraction force of the magnetic block 15 is relatively small, the module can be removed from the vehicle installation position under the action of manual outward pulling force, which facilitates subsequent replacement and repair operations and ensures the efficient performance of module maintenance work.

[0038] Working Principle: When the device is in operation, the LED light source 5 emits light. The light first undergoes preliminary light adjustment and focusing through the inner lens 4. Then, the light is projected onto the convex lens 3, which further converges and refracts the light, focusing the light that has undergone preliminary processing by the inner lens 4 into a beam that meets the requirements of high beam illumination. Finally, it is emitted from the housing 1, providing clear illumination for a long distance in front of the vehicle. The LED light source 5 generates a large amount of heat during operation. Since the heat-conducting plate 11 is attached to the back of the LED light source 5, the heat is transferred from the LED light source 5 to the heat-conducting plate 11, causing... The heat absorbed by the heat-conducting plate 11 is conducted to the evaporation section of the heat pipe 12. In the evaporation section of the heat pipe 12, the working fluid inside absorbs heat and undergoes a phase change, changing from a liquid to a gaseous state. Due to the pressure difference between the evaporation and condensation sections, the gaseous working fluid rises to the condensation section within the heat pipe 12. The condensation section of the heat pipe 12 is located inside the heat dissipation fins 13. Here, the gaseous working fluid transfers heat to the heat dissipation fins 13 and then condenses back into a liquid state. Afterward, the liquid working fluid flows back to the evaporation section through the capillary structure inside the heat pipe 12 or due to gravity. This cycle continues continuously. Heat is transferred from the LED light source 5 to the heat sink 13. The heat sink 13 has a large surface area, which can quickly dissipate heat into the surrounding air. At the same time, the fan 6 generates airflow. Part of the airflow is blown out through the multiple air holes 10 on the side wall of the mounting cylinder 8, and another part of the airflow is blown out through the gaps in the horizontal plate 9 inside the mounting cylinder 8. These blown airflows enhance the airflow near the rear cover 2, accelerate the air renewal around the heat sink 13, remove more heat, and further improve the heat dissipation effect. When installing the LED headlight high beam module, the magnetic attraction block 15 is used to... The magnetic block 15 allows the module to be initially attached to the corresponding installation position on the vehicle, serving as a pre-positioning function. Simultaneously, by opening corresponding locking holes at the installation position, the locking block 19 is squeezed and compresses the spring 18 during the sliding of the magnetic block 15. The elasticity of the spring 18 allows the locking block 19 to be locked into the corresponding locking hole for further fixation. When replacement or maintenance is required, the sliding block 17 can be moved by pulling the pulling block 21 to slide within the fixing sleeve 16, thereby squeezing the spring 18 and causing the locking block 19 to disengage from the corresponding locking hole, releasing the fixing effect. At this time, the module can be removed by pulling it outward for replacement or maintenance.
