[0002] Among related technologies, LEDs offer numerous advantages, including energy saving, high efficiency, and environmental friendliness. In recent years, they have been increasingly used in general lighting. With the rapid development of the automotive industry and the continuous improvement of LED lighting efficiency, LEDs are becoming increasingly common in automobiles, including interior lighting, brake lights, taillights, and headlights.

[0003] The current LED car lights include a lamp body and a mounting ring arranged on the lamp body. The lamp body and the mounting ring are fixedly connected. The lamp body is installed in the reflector of the LED car light through the mounting ring. The cooperation between the lamp body and the reflector affects the lighting effect of the LED car light. There are differences in the cooperation between different lamp bodies and reflectors. However, since the lamp body and the mounting ring are fixedly connected, and the connection position of the mounting ring and the reflector is fixed, the user cannot adjust the illumination angle of the lamp body by rotating the lamp body, and thus cannot adjust the cooperation angle between the lamp body and the reflector, which affects the lighting effect of the LED car light.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1: Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, this embodiment provides a plug-in LED automotive lamp, comprising:

[0027] A lamp body 1, wherein a mounting hole 100 is formed on the lamp body 1, and an LED light-emitting module 2 is arranged in the mounting hole 100;

[0028] A connector 3 is provided at the end of the lamp body 1 . A drive control module 4 is provided in the lamp body 1 and / or the connector 3 . The drive control module 4 is electrically connected to the LED light-emitting module 2 .

[0029] A chuck 5 is provided with a plurality of clamping portions 51, which are used to connect with the reflector. The chuck 5 is sleeved outside the lamp body 1 and can rotate relative to the lamp body 1.

[0030] The clamping ring 6 is provided with an annular groove 101 on the outer surface of the lamp body 1 . The clamping ring 6 is sleeved outside the lamp body 1 and embedded in the annular groove 101 . The chuck 5 is limited by the clamping ring 6 .

[0031] The direct-plug LED car lamp provided in this embodiment can adjust the lamp body to ensure or improve the lighting effect of the LED car lamp.

[0032] When the lamp body 1 is installed in the reflector through the chuck 5, if it is found that the lamp body 1 and the reflector are not properly matched, the lamp body 1 can be rotated relative to the chuck 5 to adjust the lamp body 1 and the reflector to match, thereby ensuring or improving the lighting effect of the LED car lamp.

[0033] In this embodiment, the connector 3 is fixedly connected to the lamp body 1 and is integrated therewith.

[0034] The above design is simple and reasonable. The rotatable connection mode between the chuck 5 and the lamp body 1 can be designed according to product requirements, thereby meeting the design and installation requirements of different direct-plug LED automotive lamps.

[0035] Furthermore, a heat dissipation structure 102 is provided on the lamp body 1. The heat dissipation structure 102 includes a plurality of heat dissipation ribs distributed at intervals. Its structure is simple, thereby ensuring the heat dissipation capacity of the LED car lamp and preventing the working stability of the LED car lamp from being affected by high temperature.

[0036] Furthermore, an annular protrusion 11 is provided on the lamp body 1, and a limiting groove 110 communicating with the annular groove 101 is provided on the protrusion 11. The chuck 5 includes a sleeve ring 52 and a connecting portion 53 extending outward from the sleeve ring 52. The clamping portion 51 is provided on the connecting portion 53, and the sleeve ring 52 is limited in the limiting groove 110. It has a simple structure and a reasonable design, thereby ensuring the stability and reliability of the rotatable connection between the chuck 5 and the lamp body 1.

[0037] In this embodiment, a drive motor 8 and a cooling fan 7 are provided in the lamp body 1. The drive motor 8 is electrically connected to the drive control module 4 and the cooling fan 7, respectively. The structure is simple, which can further ensure the heat dissipation capacity of the LED car lamp and prevent the working stability of the LED car lamp from being affected by high temperature.

[0038] Preferably, the thickness of the LED light emitting module 2 is 1.2 mm to 1.5 mm, so that the finished LED car lamp can be thinner and lighter.

[0039] More preferably, the LED light-emitting module 2 adopts a double-sided eutectic structure, which includes a substrate and LED chips arranged on the front and back sides of the substrate.

[0040] Double-sided eutectic packaging is a packaging method for LED chips. Its unique feature is that the LED chip is directly press-bonded to the circuit board, achieving electrical and thermal connections. This overcomes the bottleneck of traditional thermal conductivity paths, which cannot be solved without separating heat and electricity. Unlike traditional flip-chip packaging, double-sided eutectic technology shortens the chip connection path, directly eutecticizing the circuit line, reducing material thermal resistance and improving luminous efficiency. The double-sided packaging structure is chip - eutectic copper circuit - aluminum nitride substrate (tested total thermal resistance is 0.616). Single-sided packaging is: chip - eutectic to aluminum nitride substrate - solder paste - copper substrate (total thermal resistance is 2-2.5). The junction temperature calculation is: TJ = maximum substrate temperature + power * thermal resistance. The actual junction temperature of double-sided packaging is much lower than that of single-sided packaging with copper substrate (the difference is 20-30°C). The main breakthroughs of this packaging technology include: reduced electrode connection paths, reducing the number of thermal resistance layers of the chip. The packaging process is simple, does not require wire bonding, and is relatively easy to automate.

[0041] In addition, the light-emitting distance between double-sided eutectic chips is only 1.2mm, which is exactly the same as the size of tungsten filament lamps, bringing unparalleled light pattern and illumination intensity. The low thermal resistance and good thermal conductivity of aluminum parts will bring higher light efficiency, and the product complies with traffic road safety regulations.

[0042] Currently, there are very few products in the LED industry that can pass regulatory testing. Traditional chip modules need to meet regulatory standards, and precision control is very difficult. For example, controlling the amount of solder tin between the lamp beads and the copper plate, controlling the size of the lamp beads and the solder pad, the overlap of the chip sizes on both sides, and controlling the precision of aluminum processing, etc., are all quite difficult. Double-sided eutectic only needs to control the precision of the aluminum parts.

[0043] Example 2: Reference Figure 5 and Figure 6 As shown, this embodiment provides a plug-in LED automobile lamp, which is different from the first embodiment in that the connector 3 and the chuck 5 are fixedly connected and integrated.

[0044] The above design is simple and reasonable. The rotatable connection mode between the chuck 5 and the lamp body 1 can be designed according to product requirements, thereby meeting the design and installation requirements of different direct-plug LED automotive lamps.

[0045] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
