DETAILED DESCRIPTION

[0025] The utility model provides a kind of LED vehicle lamp, to make the purpose, technical scheme and effect of the utility model more clear, definite, the following referring to drawing and taking example further detailedly to the utility model of embodiment.It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the protection scope of the utility model.

[0026] Please refer to Figures 1 to 3The utility model provides a kind of LED car light, including LED lamp plate 2, power drive board 3, lamp holder 4, the heat dissipation support 51 being set in the front end of lamp holder 4, the heat dissipation support 51 includes the heat dissipation head 51, heat conduction support plate 52 and heat conduction tail seat 53 connected in order from front to back, the LED lamp plate 2 is fixedly arranged on heat conduction support plate 52, the heat conduction tail seat 53 is butt joint with lamp holder 4, one end of the power drive board 3 is electrically connected with lamp holder 4, and the other end is electrically connected with the LED lamp plate 2;Several heat dissipation holes 511 are set on the outer circumferential surface of heat dissipation head 51.

[0027] When LED car light works, lamp holder 4 is connected, and power drive board 3 supplies power for LED lamp plate 2 to make it light work. With the continuous work of LED lamp plate 2, LED lamp plate 2 generates a large amount of heat, since LED lamp plate 2 is fixed on heat conduction support plate 52, heat is first rapidly conducted to heat conduction support plate 52, and then heat is transmitted to heat dissipation head 51 and heat conduction tail seat 53 through heat conduction support plate 52. As the main heat dissipation component, the several heat dissipation holes 511 distributed on the outer circumferential surface of heat dissipation head 51 greatly increase the contact area with air. Heat dissipation head 51 is in a high temperature state because it receives heat from LED lamp plate transmitted through heat conduction support plate 52, and the surrounding air is relatively in a low temperature state. The several heat dissipation holes 511 set on the outer circumferential surface of heat dissipation head 51 not only increase the contact area of heat dissipation head 51 with air, but also form numerous heat transfer channels between heat dissipation head 51 and air. Heat is quickly transmitted to the surrounding low-temperature air in the form of heat convection and heat radiation through these heat dissipation holes 511, thereby effectively dissipating the heat of LED lamp plate 2 and ensuring the stable work of LED lamp plate 2 at a suitable temperature.

[0028] Unlike traditional LED car lights that use fans for heat dissipation, the LED car light provided by the utility model ingeniously sets several heat dissipation holes 511 on heat dissipation head 51, greatly increases the contact area of heat dissipation head 51 with air, so that heat can be more quickly transmitted from heat dissipation head 51 to the surrounding air, without the need for additional energy-consuming devices such as fans, and only relying on natural heat transfer can effectively remove the heat generated by LED lamp plate 2, ensuring that LED lamp plate 2 always maintains a suitable temperature during work, greatly improving the heat dissipation efficiency. In addition, this compact heat dissipation design provides the possibility for LED car light to develop towards miniaturization and compactness, so that the lamp can better adapt to the limited installation space of a motorcycle while meeting the heat dissipation demand, realize more reasonable layout, and improve the overall space utilization rate of the motorcycle.

[0029] In fact, the heat dissipation support 51 is made of aluminum material, so that the heat dissipation head 51, the heat conduction support plate 52 and the heat conduction tail seat 53 are integrally formed. The integrally formed ensures the close connection between the heat dissipation head 51, the heat conduction support plate 52 and the heat conduction tail seat 53, and there is no thermal resistance caused by component connection. Heat can be conducted freely in the entire heat dissipation support 51, greatly improving the heat dissipation efficiency. The aluminum material also has good heat dissipation performance and high thermal conductivity, which can quickly transfer the heat generated by the LED lamp panel 2.

[0030] In this embodiment, the heat dissipation hole 511 is a vertical through hole structure. When the LED vehicle lamp is working, hot air will naturally rise due to its small density, and be discharged upward through the vertical through hole 511, while the external cold air will be supplemented from below, forming a continuous air convection. This efficient convection mode accelerates the heat transfer, and compared with non-through or other shaped heat dissipation holes 511, it can more quickly dissipate the heat of the heat dissipation head 51 and the LED lamp panel 2 to the surrounding environment, further ensuring that the LED lamp panel 2 works at an appropriate temperature and improving the overall heat dissipation efficiency.

[0031] Further, the inner wall of the heat dissipation hole 511 forms a wave pattern surface 512. The wave pattern surface 512 significantly increases the contact area between the inner wall of the heat dissipation hole 511 and the air. When heat is transferred through the heat dissipation hole 511, a larger contact area means more opportunities for heat exchange. When air flows through the wave pattern surface 512, it forms more complex turbulence, so that heat transfer is no longer limited to simple convection, and the heat conduction efficiency between the air and the wall of the heat dissipation hole 511 is enhanced. This enhanced heat transfer mechanism can more quickly dissipate the heat of the heat dissipation head 51 to the surrounding air, effectively reducing the temperature of the LED lamp panel 2 and ensuring its efficient and stable operation.

[0032] Further, the heat dissipation hole 511 is in the shape of a waist extending front and back and is provided with three, the three heat dissipation holes 511 are arranged in a left-right interval. The design of the waist-shaped and front-back extending heat dissipation hole 511 increases the size of the heat dissipation hole 511 in the front-back direction, which is conducive to the smooth flow of air in the heat dissipation head 51, forming an efficient convection channel. Compared with other shapes such as circular heat dissipation holes 511, the waist-shaped hole can make more air flow through the inside of the heat dissipation head 51, carrying away more heat. The three heat dissipation holes 511 are arranged in a left-right interval, and the layout is relatively uniform, avoiding the situation of excessive or insufficient local heat dissipation, which helps to balance the overall heat dissipation. It not only ensures the overall structural strength of the heat dissipation head 51, but also maximizes the heat dissipation area in a limited space, further improving the heat dissipation efficiency and ensuring that the heat generated by the LED lamp panel 2 can be quickly dissipated to maintain its stable working temperature.

[0033] In other embodiments, the heat dissipation hole 511 can also be provided as a blind hole structure, and the heat dissipation area on the surface of the heat dissipation head 51.

[0034] Specifically, the heat dissipation head 51 is in a round head structure, which has significant processing advantages in the manufacturing process. The round profile is easier to be accurately processed by conventional turning, grinding and other processes than a complex special-shaped structure, thereby reducing the manufacturing cost.

[0035] To further improve the heat dissipation effect of the heat dissipation head 51, a plurality of vertically extending and left-right spaced heat dissipation ribs 513 are arranged on the front end face of the heat dissipation head 51, that is, a heat dissipation groove 514 is formed between adjacent two heat dissipation ribs 513, which greatly expands the heat dissipation surface area. It can be understood that the heat dissipation grooves 514 formed between the adjacent two heat dissipation ribs 513 not only have a spatial interval, but also play a crucial role in the heat dissipation process. When the heat generated by the LED lamp panel 2 is transferred to the heat dissipation head 51, the heat dissipation grooves 514 can promote the formation of natural convection of air. The hot air rises in the groove due to thermal expansion, and the surrounding cold air quickly supplements to form a continuous and efficient air circulation, which continuously takes away the heat, so as to ensure that the LED lamp panel 2 can maintain an appropriate working temperature even in a relatively closed environment inside the lampshade, effectively prolonging its service life and improving the light stability.

[0036] Preferably, the tail of the heat dissipation head 51 is designed in a spreader shape, which can form a smooth transition connection between the tail of the heat dissipation head 51 and the heat conduction branch plate 52, and can also form two left-right symmetrical and large-area heat dissipation arc surfaces 515. The two large-area heat dissipation arc surfaces 515 significantly increase the heat dissipation area of the tail of the heat dissipation head 51, which makes the heat transferred from the LED lamp panel 2 to the tail of the heat dissipation head 51 through the heat conduction branch plate 52 be dissipated to the surrounding environment more quickly and efficiently, further improving the heat dissipation capacity of the entire heat dissipation system, ensuring that the LED lamp panel 2 is always in an appropriate working temperature range, and reducing the performance degradation and service life shortening problems caused by overheating.

[0037] In the first embodiment, referring to Figures 1 to 3 , the left and right sides of the heat conduction branch plate 52 are each provided with an LED lamp panel 2. The two LED lamp panels 2 can be fixed on the heat conduction branch plate 52 by rivets 6 or in other ways (such as by adhesive). The LED lamp panel 2 on the left side is provided with a first lamp bead group 21, and the LED lamp panel 2 on the right side is provided with a second lamp bead group 22. The heat conduction branch plate 52 is provided with the LED lamp panel 2 on the left and right sides, respectively equipped with the first lamp bead group 21 and the second lamp bead group 22. This layout greatly increases the light emitting area. The lamp bead groups on both sides work together to produce brighter and more uniform light, effectively improving the illumination brightness and range of the LED vehicle lamp, providing a better view for vehicle driving, and enhancing the driving safety.

[0038] In the embodiment, the first lamp bead group 21 and the second lamp bead group 22 are each configured with 6 lamp beads, and the 6 lamp beads are closely arranged in a rectangular array. The reasonable layout of each group of 6 lamp beads makes the light distribution more uniform, forms a wider and brighter illumination range, provides a comfortable and non-dazzling lighting environment for the driver, and obtains a wider field of view. Whether on a curve or a straight road, the driver can clearly see the road conditions, the surrounding environment and potential obstacles, greatly improving the safety of night driving.

[0039] In order to form a reliable electrical connection between the power driving board 3 and the LED lamp board 2, the power driving board 3 is located in the heat-conducting tail seat 53 and the lamp holder 4, and the power driving board 3 and the LED lamp board 2 are perpendicular to each other, and the front end of the power driving board 3 forms a clamping groove 31 for inserting the rear end of the heat-conducting branch plate 52 and the two LED lamp boards 2. When installing, the staff only needs to align the LED lamp board 2 with the rear end of the heat-conducting branch plate 52 and insert it into the clamping groove 31, which can quickly complete the preliminary positioning. This avoids the tedious steps of repeated adjustment of position in the traditional installation method, greatly shortens the installation time, improves the production efficiency, and especially in large-scale production of LED car lights, can significantly improve the overall assembly speed. After the clamping groove 31 accurately positions the LED lamp board 2 and the heat-conducting branch plate 52, it creates very convenient conditions for subsequent soldering work. Because the position of the components is fixed, the staff can more easily perform soldering operations on the connection part and accurately form solder joints at the predetermined position. This not only improves the efficiency of soldering, but also ensures the quality of the solder joints, reduces the occurrence of problems such as virtual welding and missed welding, thereby enhancing the reliability of the electrical connection between the LED lamp board 2 and the power driving board 3, and ensuring the stable operation of the circuit of the LED car light during long-term use.

[0040] Since the power driving board 3 also generates heat during operation, the lamp holder 4 and the heat-conducting tail seat 53 are filled with heat-conducting resin, so that the power driving board 3 and the heat-conducting tail seat 53 form heat transfer. Because the heat-conducting resin has good heat conduction performance, it can greatly shorten the heat transfer path, so that the heat of the power driving board 3 is promptly dissipated, avoiding the accumulation of heat causing the temperature of the power driving board 3 to be too high. This helps to maintain the power driving board 3 within an appropriate working temperature range, ensures its stable performance, reduces problems such as aging, performance degradation or even damage of electrical components caused by overheating, thereby prolonging the service life of the power driving board 3.

[0041] Further, the power connection end of the lamp holder 4 is a contact structure 41, which can provide reliable electrical connection. The contact structure 41 generally has good electrical conductivity and elasticity, and can achieve close contact with the external power supply to ensure stable transmission of current to the internal components of the LED vehicle lamp. During the driving of the motorcycle, even if affected by external forces such as vibration and bumping, the elastic design of the contact can maintain good contact with the power supply, reducing the probability of problems such as flickering and extinguishing of the vehicle lamp caused by poor contact, and providing solid power guarantee for stable operation of the LED vehicle lamp. In addition, the lamp holder 4 is provided with a positioning ring 43, which facilitates installation alignment when the LED vehicle lamp is installed with the lampshade, and also plays a positioning role in limiting the rotation of the LED vehicle lamp.

[0042] In a second embodiment, referring to Figure 4 and Figure 5 , the left side or right side of the heat-conducting branch plate 52 is provided with the LED lamp plate 2, that is, only one LED lamp plate 2 is installed, which can be fixed on the heat-conducting branch plate 52 by rivets 6 or in other ways (such as adhesive paste), and the heat-conducting branch plate 52 is provided with a left-right through avoiding opening 521, and one end surface of the LED lamp plate 2 is provided with a third lamp bead group 23, and the other end surface is provided with a fourth lamp bead group 24 located in the avoiding opening 521. On the basis of ensuring that the lighting requirement reaches the standard, compared with the design of installing LED lamp plates 2 on both sides, only one LED lamp plate 2 is used to reduce the cost of raw materials. At the same time, the installation and wiring of a single lamp plate are relatively simple, which reduces the assembly difficulty and time cost in the production process, improves the production efficiency, reduces the area where heat is concentrated, and reduces the overall heat dissipation burden.

[0043] In order to form reliable electrical connection between the power supply driving board 3 and the LED lamp plate 2, the power supply driving board 3 is located in the heat-conducting tail seat 53 and the lamp holder 4, and the power supply driving board 3 and the LED lamp plate 2 are perpendicular to each other, and the front end of the power supply driving board 3 forms a clamping groove 31 for the LED lamp plate 2 and the rear end of the heat-conducting branch plate 52 to be inserted, which facilitates the installation alignment and soldering operation of the power supply driving board 3.

[0044] Since the power supply driving board 3 will also generate heat during operation, the lamp holder 4 and the heat-conducting tail seat 53 are filled with heat-conducting resin, so that the power supply driving board 3 and the heat-conducting tail seat 53 form heat transfer. Since the heat-conducting resin has good heat conduction performance, it can greatly shorten the heat transfer path, so that the heat of the power supply driving board 3 is dissipated in time, avoiding the accumulation of heat to cause the temperature of the power supply driving board 3 to be too high. This helps to maintain the power supply driving board 3 within a suitable working temperature range, ensures its stable performance, reduces problems such as aging, performance degradation, and even damage of electrical components caused by overheating, thereby prolonging the service life of the power supply driving board 3.

[0045] The power connection end of the lamp holder 4 is a pin structure 42, which can provide stable and reliable electrical connection. The pin is usually tightly matched with the corresponding socket to form a stable connection after insertion. This tight connection can effectively reduce the contact resistance and ensure efficient transmission of electrical energy to the inside of the LED vehicle lamp. During the driving of the motorcycle, even if it is subjected to vibration, bumping and other conditions, the pin is not easy to loosen or separate from the socket, thereby ensuring that the LED vehicle lamp continuously and stably obtains power supply and reducing the problem of light flickering, extinguishing and the like caused by poor contact. In addition, the lamp holder 4 is provided with a positioning ring 43, which facilitates installation alignment when the LED vehicle lamp and the lampshade are installed, and also plays a positioning role in limiting the rotation of the LED vehicle lamp.
