Description

Technical Field

[0001] The utility model relates to the technical field of LEDs, in particular to a high thermal conductivity LED vehicle lamp. Background Art

[0002] LED headlights are widely used in modern automotive lighting systems due to their excellent energy efficiency and long life. These LED headlights are usually integrated with heat dissipation structures to handle the heat generated by LED components during operation.

[0003] However, the heat dissipation structure of existing LED headlights often cannot fully solve the heat dissipation problem, especially in high-power or long-term operation application scenarios. Because the material, design or overall layout of the heat dissipation structure may not be ideal, heat accumulates around the LED components, causing the temperature to be too high, which not only affects the light output efficiency of the LED, but may also cause premature aging and failure of the LED components. Therefore, the lack of heat dissipation in the existing technology has become a technical challenge that needs to be urgently solved in the development of LED headlights. Utility Model Content

[0036] Refer to Figures 1-4, a highly thermally conductive LED headlight is proposed, which includes a lamp body 1 and a heat dissipation base 5 connected to the lamp body 1. An LED substrate 2 is provided on the lamp body 1, and an LED lamp bead 21 and a heat pipe 22 are provided on the LED substrate 2. The LED lamp beads 21 are electrically connected to each other. The heat pipe 22 is connected to the heat dissipation base 5. The heat dissipation base 5 further includes a plurality of heat dissipation ribs 55. The plurality of heat dissipation ribs 55 are arranged vertically and / or obliquely on the heat dissipation base 5. The plurality of heat dissipation ribs 55 form a receiving cavity 56, and a heat dissipation fan 51 is further provided in the receiving cavity 56, where:

[0037] The heat pipe 22 is used to conduct the heat on the LED lamp bead 21 to the heat dissipation ribs 55 through the heat dissipation base 5, and the heat dissipation fan 51 is used to accelerate the transfer of the heat of the plurality of heat dissipation ribs 55 to the external environment.

[0038] In the embodiment of the present utility model, a heat pipe and a plurality of heat dissipation ribs are provided. The heat pipe is directly attached to the LED substrate and is used to absorb heat from the LED lamp bead. Utilizing its high thermal conductivity, the heat is quickly conducted from the LED lamp bead to the heat dissipation base. In the heat dissipation base, the heat is further transferred to the plurality of heat dissipation ribs. By enhancing the air flow through the heat dissipation fan, the heat exchange efficiency is greatly improved, the operating temperature of the LED lamp bead is significantly reduced, and the performance stability and lifespan of the lamp bead are improved.

[0039] In the embodiment of the present utility model, the heat dissipation ribs are arranged on the heat dissipation base in a specific vertical and / or oblique angle manner, significantly increasing the heat dissipation surface area and optimizing the air convection, thereby promoting faster heat transfer. With the assistance of the heat dissipation fan, efficient external discharge of heat energy is achieved, and the operating temperature of the LED lamp bead is significantly reduced.

[0040] Preferably but not limitedly, the end of the heat dissipation rib can be designed to be serrated or wavy. Such non-linear edges can increase the area of contact with the air, thereby enhancing the heat dissipation performance.

[0041] Preferably but not limitedly, the heat dissipation ribs are placed upright and perpendicular to the bottom surface of the heat dissipation base. This arrangement provides a large surface area, which is conducive to air flowing in from the bottom and flowing out from the top, forming natural convective heat dissipation.

[0042] Preferably but not limitedly, the heat dissipation ribs are placed at an angle. This design can increase the turbulence of the air flow and improve the heat dissipation efficiency. The selection of the inclination angle is usually based on optimizing the air flow and increasing the heat dissipation surface area.

[0043] Preferably but not limitedly, the heat dissipation ribs are placed staggeredly, with some being vertical and some being inclined. This mixed arrangement is designed to combine the advantages of vertical arrangement and oblique angle arrangement. By different heat dissipation rib gaps and angles, more air flow channels and surface areas are created, thereby enhancing the heat dissipation performance.

[0044] Optionally, the heat dissipation ribs 55 include main heat dissipation ribs 551 and auxiliary heat dissipation ribs 552, wherein the main heat dissipation ribs 551 are protruding longitudinal extension structures and / or recessed longitudinal extension structures in their length direction, and the auxiliary heat dissipation ribs 552 are column structures.

[0045] In this embodiment, the protruding longitudinal extension structure and / or the concave longitudinal extension structure introduced in the design of the main heat dissipation rib 551 significantly enhances the heat dissipation performance. This structural design increases the surface area of ​​the heat dissipation rib in contact with the air, thereby improving the heat exchange efficiency. The protruding and concave parts create more surface irregularities, which not only helps to break the laminar state of the surrounding air, but also promotes a stronger convection effect. Therefore, heat can be transferred from the LED lamp beads to the heat dissipation ribs more quickly and quickly dissipated into the environment through these complex surface structures, thereby effectively reducing the operating temperature of the LED lamp beads and improving the stability and efficiency of the overall lighting device.

[0046] The auxiliary heat dissipation ribs 552 adopt a column structure design, which is beneficial to maximizing the heat dissipation surface area within a limited space. The auxiliary heat dissipation ribs of the column structure help to form an effective heat channel and accelerate heat flow, thereby more effectively directing heat from the heat sink to the external air. In addition, the column shape also helps to enhance the structural stability of the heat sink, ensuring the reliability and durability of the heat dissipation system during vehicle driving.

[0047] As a preference but not limitation, the heat dissipation ribs are designed with protruding ridge-like or ridge-like structures, which extend along the length direction of the heat dissipation ribs. The protruding ridge-like structures can increase the surface area of ​​the heat dissipation ribs in contact with the air and improve the heat dissipation efficiency. Specifically, the protruding ridge-like structures are reflected on the heat dissipation ribs as a series of continuous, protruding lines or ridges, which extend evenly along the length direction of the heat dissipation ribs.

[0048] As a preferred but not limiting example, a concave groove or groove structure is designed on the surface of the heat dissipation rib. This design can create more surface area and promote air flow, thereby enhancing heat exchange capacity. Specifically, the concave groove structure is embodied on the heat dissipation rib as a series of grooves cut evenly along the length of the heat dissipation rib. These groove structures penetrate into the surface of the heat dissipation rib, similar to the elongated grooves carved on a straight rod. Each groove is parallel to the long axis of the heat dissipation rib and is distributed along the entire length of the heat dissipation rib.

[0049] As a preference rather than a limitation, a protruding ridge structure is designed on one side of the heat dissipation rib, while a concave groove structure is designed on the other side. This design of the heat dissipation rib that combines a protruding ridge structure and a concave groove structure is an efficient heat dissipation solution, and its structural feature is that there are two different surface morphologies on one heat dissipation rib. For example, the heat dissipation rib is a cuboid, and on one side surface of this cuboid, a protruding ridge structure is designed. These ridges are like mountain ridges, extending along the length direction of the heat dissipation rib and protruding from the basic plane. These ridges can be sharp or smooth, and they improve the heat dissipation effect by increasing the physical surface area in contact with air.

[0050] Optionally, the auxiliary heat dissipation ribs 552 and the main heat dissipation ribs 551 are spaced and evenly distributed around the heat dissipation base 5.

[0051] In this embodiment, the design that the auxiliary heat dissipation ribs 552 and the main heat dissipation ribs 551 are spaced and evenly distributed around the heat dissipation base 5, combined with the application of the heat dissipation fan, greatly enhances the overall heat dissipation effect. This configuration enables the cold air blown by the fan to flow evenly through each heat dissipation rib, effectively taking away the heat, and the existence of the spacing ensures that the air flow is not blocked, thereby optimizing the aerodynamic characteristics and improving the heat dissipation efficiency and the overall performance of the system.

[0052] Specifically, the spacing between the main heat dissipation ribs 551 and the auxiliary heat dissipation ribs 552 is about 0.1 - 100 millimeters, where:

[0053] A spacing of about 5 millimeters between the main heat dissipation ribs 551 and the auxiliary heat dissipation ribs 552 is applicable to a smaller heat dissipation base or to increase the density of the heat dissipation ribs when the heat dissipation requirement is high and the space permits.

[0054] A spacing of about 10 millimeters between the main heat dissipation ribs 551 and the auxiliary heat dissipation ribs 552 is a common design that balances heat dissipation efficiency and space utilization and is suitable for most LED headlight applications.

[0055] A spacing of about 15 millimeters between the main heat dissipation ribs 551 and the auxiliary heat dissipation ribs 552 allows more air flow. This is suitable for use in applications with sufficient installation space and can provide better heat dissipation effect.

[0056] In addition, for the application of the heat dissipation fan 51, a potential optimization direction is to adjust its wind direction setting to suck in air from the external environment and discharge the hot air out through the gaps of the heat dissipation ribs 55. This configuration can effectively utilize the cold air in the environment to directly cool the heat generated by the LED lamp beads 21, thereby improving the heat exchange efficiency.

[0057] Specifically, after the fan inhales external cold air, the air flows through the preheated heat dissipation ribs 55. At this time, the heat dissipation ribs have greatly increased their contact area with the air due to their optimized structure (such as vertical or oblique arrangement), which promotes the rapid transfer and dissipation of heat. Subsequently, the heated air is discharged from the gaps between the heat dissipation ribs. In this process, the hot air takes away a large amount of heat energy, effectively reducing the operating temperature of the LED lamp beads. This wind direction design also helps to avoid heat accumulation caused by internal hot air circulation and maintain the efficient operation of the heat dissipation system. In actual applications, the speed of the cooling fan can be intelligently adjusted according to the real-time temperature of the LED lamp beads and external environmental conditions to achieve optimal heat dissipation performance. Wind direction optimization not only improves the heat dissipation efficiency, but also helps to maintain the long-term stability and reliability of the LED lamps.

[0058] Optionally, the LED substrate 2 also includes a first mounting hole 23 and a second mounting hole 24, and the first mounting hole 23 and the second mounting hole 24 are located on both sides of the LED lamp bead 21 along the length direction of the LED substrate 2, and the LED substrate 2 is connected to the lamp body 1 through the first mounting hole 23 and the second mounting hole 24.

[0059] In this embodiment, the LED substrate 2 is connected to the lamp body 1 through the first mounting hole 23 and the second mounting hole 24 by setting mounting holes on both sides of the LED substrate, thereby providing a sturdy and reliable fixing method, ensuring the stability of the LED substrate during vehicle operation. In addition, this symmetrical layout along the length direction of the LED substrate helps to balance the stress distribution on the LED substrate and reduce the risk of deformation caused by vibration or thermal expansion. It not only improves the overall structural strength of the LED car lamp, but also optimizes thermal management, because the position of the fixing point helps to better transfer the heat generated by the LED lamp beads to the lamp body and finally dissipate it into the environment.

[0061] In this embodiment, the third mounting hole 31 and the fourth mounting hole 32 on the mounting plate 3 correspond to the first mounting hole 23 and the second mounting hole 24 on the LED substrate 2, ensuring the precise alignment and fixation between the LED substrate and the mounting plate, thereby enhancing the stability and seismic resistance of the overall structure. In addition, the design of the heat pipe receiving groove 34 is opposite to the position of the heat pipe 22, optimizing the layout of the heat pipe, enabling the heat generated from the LED lamp beads 21 to be conducted to the heat pipe more efficiently and quickly dissipated to the outside through the heat pipe, improving the heat dissipation efficiency. The setting of the first light-emitting hole 33 is opposite to the position of the LED lamp beads 21, and such alignment ensures the direct and efficient transmission of light, enhancing the quality and directivity of the light effect output.

[0062] Optionally, a light-shielding fixing member 4 is further provided on the lamp body 1. A fifth mounting hole 41 corresponding to the position of the first mounting hole 23 is provided on the light-shielding fixing member 4, and a sixth mounting hole 42 corresponding to the position of the second mounting hole 24 is provided on the light-shielding fixing member 4. The first mounting hole 23, the third mounting hole 31, and the fifth mounting hole 41 are fixed with screws, and the second mounting hole 24, the fourth mounting hole 32, and the sixth mounting hole 42 are fixed with screws. A second light-emitting hole 43 corresponding to the position of the LED lamp beads 21 is further provided on the light-shielding fixing member 4.

[0063] In this embodiment, the fifth mounting hole 41 and the sixth mounting hole 42 on the light-shielding fixing member 4 correspond to the first mounting hole 23 and the second mounting hole 24 on the LED substrate 2, as well as the third mounting hole 31 and the fourth mounting hole 32 on the mounting plate 3. By using screws for fixation, a three-point support system is formed. This design greatly improves the mechanical strength and seismic resistance of the overall device. In addition, the setting of the second light-emitting hole 43 corresponds to the position of the LED lamp beads 21, ensuring that light can be efficiently output through the light-shielding fixing member 4, while reducing light pollution and light loss. It not only optimizes the light transmission path but also ensures the consistency and efficiency of the light effect, and significantly improves the lighting performance and durability of the entire LED headlight system.

[0064] Optionally, it further includes a chuck 11, and the chuck 11 is sleeved and connected to the lamp body 1.

[0065] In this embodiment, the design of the chuck 11 is sleeved and connected to the lamp body 1, providing enhanced structural connection for the entire LED headlight system, effectively improving the stability between the lamp body and the mounting surface, and ensuring the ability to resist vibration and impact during vehicle operation. Through this firm fixing method, the chuck 11 not only enhances the mechanical strength of the entire lamp body but also ensures the reliability and safety during long-term use, preventing loosening or damage of the connection caused by frequent vibration.

[0066] Optionally, it further includes a power supply interface 53, the power supply interface 53 is electrically connected to the LED substrate 2, and the main heat dissipation rib 551 and the auxiliary heat dissipation rib 552 further form a notch 57, and the notch 57 is used to accommodate the power supply interface 53.

It not only maintains the integrity of the heat dissipation structure but also ensures the easy access and replacement of the power supply interface, facilitating quick repair and upgrade. In addition, the existence of the notch 57 allows the power supply interface to be closely integrated with the heat dissipation rib, thereby reducing the need for additional space and making the overall lamp body structure more compact and efficient.
