[0025] The following will make a detailed description of the implementation manner of the present utility model with reference to the accompanying drawings.

[0026] Please refer to Figures 1 to 8 , an LED car lamp, comprising a lamp body 1 of the car lamp, the lamp body 1 of the car lamp comprising a lamp cover 2, a first light source board 3, a top light source board 4 connected to the first light source board 3, a lamp body 5 connected to the lamp cover 2, and a lamp base 6 connected to the lamp body 5. Side lights 31 are provided on both sides of the first light source board 3, and a top light 41 is provided on the upper side of the top light source board 4. The side lights 31 and the top light 41 are located inside the lamp cover 2. The lamp cover 2 is used to protect the light source inside the LED car lamp and help the light to be evenly diffused. The first light source board 3 and the side lights 31 provide a light source for side illumination of the LED car lamp. At the same time, by providing the top light source board 4 and arranging a top light 41 for top illumination on the top light source board 4, the illumination direction of the internal light source of the LED car lamp is increased, solving the problem that the existing LED car lamp can only irradiate in two opposite directions, resulting in a dark area in the irradiation area of the LED lamp, and effectively improving the functionality and practicality of the LED car lamp.

[0027] Further, please refer to Figures 1 to 8, an LED automotive lamp, at least one protrusion 32 is provided at the front end of the first light source board 3, the top light source board 4 is provided with a connecting portion 42 matching the protrusion 32, and the protrusion 32 is connected to the connecting portion 42 to fix the top light source board 4 to the first light source board 3. Through the cooperation of the protrusion 32 and the connecting portion 42, the top light source board 4 can be accurately positioned and tightly fixed to the first light source board 3, ensuring a stable connection between the two light source boards and avoiding loosening or displacement caused by vibration during vehicle driving. In some embodiments, by welding at the connection between the first light source board 3 and the top light source board 4, the electrical connection between the first light source board 3 and the top light source board 4 is realized, and the connection between the first light source board 3 and the top light source board 4 is further fixed, effectively improving the connection reliability between the two light source boards and the reliability of the LED automotive lamp.

[0028] Further, please refer to Figures 1 to 8 , an LED automotive lamp, the number of the side lights 31 is at least two, and they are symmetrically distributed on both sides of the first light source board 3. Adopting such a design means that at least two LED lamp beads are provided on both sides of the first light source board 3 to provide side lighting, and the symmetric distribution of the side lights 31 on both sides of the first light source board 3 helps to provide a more uniform side lighting effect for the LED automotive lamp, avoiding uneven lighting of the LED automotive lamp caused by uneven distribution of the LED lamp beads, thereby affecting the overall lighting effect of the LED automotive lamp. Therefore, adopting such a design can effectively improve the practicability and functionality of the LED automotive lamp.

[0029] Further, please refer to Figures 1 to 8 , an LED automotive lamp, the number of the top lights 41 is at least one, and the light emitting direction of the top lights 41 is perpendicular to the light emitting direction of the side lights 31. The light emitting direction of the top lights 41 and the light emitting direction of the side lights are set to be perpendicular to each other, realizing the simultaneous coverage of light in the horizontal and vertical directions, forming a three-dimensional lighting effect, which can more comprehensively illuminate the road ahead and the surrounding environment, reduce blind spots, effectively improve the functionality of the LED automotive lamp. At the same time, the top lights 41 supplement the insufficient lighting of the side lights 31 in the vertical direction, improving the lighting efficiency of the LED automotive lamp, reducing the lighting dark area, and effectively improving the performance of the LED automotive lamp.

On the upper surface of the lamp cover 2 there are a plurality of second ridges 22, and the plurality of second ridges 22 are evenly distributed. On the side of the lamp cover 2 there are a plurality of heat dissipation holes 24, and the plurality of heat dissipation holes 24 are evenly distributed.

Further, the design of the first ridges 21 and the second ridges 22 can increase the surface area of the lamp cover 2, effectively improving the heat dissipation capacity of the LED car lamp. The heat generated when the LED light source works can be transferred to the air through the lamp cover 2, thereby reducing the temperature of the light source, effectively improving the stability and service life of the LED car lamp. Further, the design of the heat dissipation holes 24 enables the heat generated inside the LED car lamp to diffuse to the outside through the heat dissipation holes 24, improving the heat dissipation efficiency of the LED car lamp, effectively reducing the working temperature of the LED car lamp, and further effectively improving the service life and stability of the LED car lamp.

[0031] Further, on the surface of the light source board 3 there is a printed circuit, and the circuit serves to electrically connect the side lights 31 on the light source board and other electrical components. Further, the circuit also serves for heat dissipation. Since the circuit is printed on the surface of the light source board 3, the heat generated by the side lights 31 can be propagated to the air through the surface of the circuit, thereby accelerating the heat dissipation of the side lights 31, reducing the temperature of the side lights 31, preventing the side lights 31 from being damaged due to excessive temperature, and effectively improving the stability and reliability of the LED car lamp.

[0032] Further, please refer to Figures 1 to 8 , an LED car lamp, on the side of the lamp cover 2 there are two oppositely arranged arc surfaces 23, and the arc surfaces 23 are arranged corresponding to the side lights 31. The arc surfaces 23 arranged corresponding to the side lights 31 can guide the light emitted by the side lights 31 to propagate in a predetermined direction, effectively reducing the scattering and waste of light, improving the utilization rate and illumination effect of the light. At the same time, the reflection effect of the arc surfaces 23 can further enhance the diffusion range of the light, making the illumination more uniform and bright, and effectively improving the functionality of the LED car lamp.

[0033] Further, please refer to Figures 1 to 8, an LED car light, the lamp body 5 is provided with a card slot 51, the card slot 51 runs through the lamp body 5, and the card slot 51 is used to fix the first light source board 3. The design of the card slot 51 makes the installation and disassembly of the first light source board 3 simple. The first light source board 3 can be snapped in or taken out without complex fixing parts, effectively improving the production efficiency and maintenance efficiency of the LED car light. The card slot 51 runs through the lamp body 5, providing stable support and fixation for the first light source board 3, and can effectively ensure that the first light source board 3 will not loosen or fall off due to vibration or impact during use, ensuring the stability and reliability of the LED car light.

The design of the first groove 61 provides a space for accommodating the first extension 52, enabling the lamp body 5 and the lamp base 6 to be tightly connected, improving the integrity of the LED car light. And the cross-sectional diameter of the first groove 61 being smaller than the cross-sectional diameter of the arc-shaped protrusion 53 enables the arc-shaped protrusion 53 to be fixedly snapped into the second groove 62, playing a role in fixing the lamp body 5 and the lamp base 6. During the installation process, only need to align the first extension 52 with the first groove 61 and gently press to make the arc-shaped protrusion 53 snap into the second groove 62 to complete the connection between the lamp body 5 and the lamp base 6. Using this design does not require additional connecting parts for connection, simplifies the installation of the LED car light, effectively improves the production efficiency of the LED car light and reduces the production cost.
