[0002] Currently, with the increasing demands for intelligent driving and aesthetic design, LED automotive lights are developing towards higher brightness, miniaturization, and integration. However, in practice, it has been found that the traditional heat dissipation method for LED automotive lights typically involves setting heat dissipation fins on the heat sink housing of the lamp body, along with a cooling fan, as shown in the "An LED Automotive Light" described in patent number "CN201820131991.0". Clearly, traditional LED automotive lights mostly require additional space (height and radial) for the cooling fan installation, significantly increasing the overall size of the lamp, especially adding unnecessary vertical height, making it difficult to adapt to compact automotive lamp housings. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing LED automotive lights, such as the need for additional space for cooling fans, which significantly increases the overall size of the light fixture, especially adding unnecessary vertical height, making it difficult to adapt to compact car light housings. Therefore, this invention proposes an LED automotive light with an embedded heat sink.

A conductive plug 12 is provided at the bottom of the lamp body heat sink housing 1 to be electrically connected to the rectifier board 33 on the PCB driver board 3.

[0006] Furthermore, the rectifier board 33 is located at the bottom of the PCB driver board 3. The rectifier board 33 is provided with a first slot 331 for the conductive plug 12 pins to be inserted and soldered, and a second slot 332 for the bottom pins of the PCB driver board 3 to be inserted and soldered.

[0007] Furthermore, a second LED light source component 34 is provided on the rear end face of the PCB driver board 3, and a second window 16 is provided on the heat dissipation shell 1 of the lamp body to expose the second LED light source component 34. The opening 32 is also located below the second LED light source component 34.

[0008] Furthermore, a heat pipe 35 located on one side of the cooling fan 4 is attached to the front end face or the front and rear end face of the PCB driver board 3.

[0009] Furthermore, the air outlet of the cooling fan 4 faces the first LED light source 31 and the second LED light source 34; and / or, the air outlet of the cooling fan 4 faces the heat pipe 35; and / or, the air outlet of the cooling fan 4 faces the first LED light source 31, the second LED light source 34 and the heat pipe 35.

[0010] Furthermore, the first window 11 can also be detachably provided with a light-blocking strip 6 located above the light outlet of the reflector cup 5.

[0011] Furthermore, the lamp body heat dissipation housing 1 includes a first housing body 13 and a second housing body 14 that are disposed with the front and rear covers. The length of the first housing body 13 is less than that of the second housing body 14. The first window 11 is formed between the top end of the first housing body 13 and the top end of the second housing body 14. The top end of the second housing body 14 is provided with a lens fixing member 141 for fixing the lens 2 therein.

[0012] Alternatively, the lamp body heat dissipation housing 1 includes a first housing body 13 and a second housing body 14 that are left and right overlapping each other. A lens fixing member 141 is formed between the top ends of the first housing body 13 and the second housing body 14, and the first window 11 is located below the lens fixing member 141.

[0013] Furthermore, the cooling fan 4 includes a fan fixing member 41 fixed inside the opening 32, the fan fixing member 41 is provided with a fan main member 42, and the top of the fan fixing member 41 is provided with ventilation holes 43 that communicate with the inside of the lamp body heat dissipation shell 1.

[0014] Furthermore, the lamp body heat dissipation shell 1 is provided with a plurality of slots 15 that communicate with the interior of the lamp body heat dissipation shell 1.

[0015] Furthermore, the lamp body heat dissipation shell 1 is fitted with a chuck 7 fixedly connected to the headlight assembly. The chuck 7 is an integrated or separate structure formed by die casting or extrusion.

[0016] The LED automotive light with an embedded heat sink proposed in this utility model has the following advantages:

[0017] In this invention, by integrating the cooling fan with the PCB driver board, this integrated design makes full use of the PCB driver board's space, avoiding the cooling fan occupying additional internal space of the lamp body. This makes the entire LED automotive lamp structure more compact, reducing the lamp body's size and facilitating installation and use in automobiles. It also avoids the problem of low heat dissipation efficiency caused by excessively long airflow paths in traditional external fan solutions. Furthermore, the design of the lamp body's heat dissipation shell is simpler, avoiding the increased size caused by external heat dissipation devices.

[0018] Secondly, in this invention, the cooling fan is embedded in the PCB driver board and located below the LED light source component. This design allows the cooling fan to directly dissipate heat from the LED light source component at close range, resulting in a short airflow path and high heat dissipation efficiency.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1-6 An LED automotive light with an embedded heat sink includes a heat sink housing 1 and a lens 2 disposed on the top of the heat sink housing 1. The heat sink housing 1 is typically made of a high thermal conductivity material (such as aluminum alloy), which can dissipate the heat generated inside to the surrounding environment through the surface of the housing. At the same time, the heat sink fins on the heat sink housing 1 can further increase the heat dissipation area and improve the heat dissipation efficiency. The lamp body heat dissipation housing 1 houses a PCB driver board 3 and a cooling fan 4. A first LED light source 31 is located on the front surface of the PCB driver board 3. The lamp body heat dissipation housing 1 has a first window 11 that exposes the first LED light source 31 and provides a light emission channel for it. The first window 11 has a reflector 5 that covers the first LED light source 31 and faces the lens 2. The PCB driver board 3 also has an opening 32 for the cooling fan 4 to be embedded and installed therein. The opening 32 is located below the first LED light source 31. The cooling fan 4 is embedded and installed on the PCB driver board 3 through this opening, which can directly dissipate heat from the high-temperature area below the first LED light source 31, while reducing the space occupied by the cooling fan. This achieves an integrated design of the heat dissipation system and the circuit board. The bottom of the lamp body heat dissipation housing 1 has a conductive plug 12 that is electrically connected to the rectifier board 33 on the PCB driver board 3. The rectifier board 33 can convert the vehicle power supply into the DC power required by the first LED light source 31 and also power the fan.

[0028] In this invention, after the LED car light is installed on the car, the conductive plug 12 is connected to the car's power system. External AC power enters the rectifier board 33 on the PCB driver board 3 through the conductive plug 12. The rectifier board 33 can convert the input AC power into DC power suitable for the operation of the first LED light source 31, providing a stable power supply for the first LED light source 31. Subsequently, the first LED light source 31 can emit light under the action of DC power. The light emitted by the first LED light source 31 can be emitted through the first window 11 and shine on the reflector cup 5. The reflector cup 5 can reflect and converge the light, making the light more concentrated and directed towards the lens 2. The lens 2 focuses and shapes the light emitted from the reflector cup 5, so that the light is emitted at a specific angle and direction, providing illumination for the car. During the operation of the lamp, the PCB driver board 3 and the first LED light source 31 will generate heat. At this time, the cooling fan 4 will start, which can generate vertical airflow and accelerate the flow of air inside the lamp body heat dissipation shell 1. The cold air drawn in from the bottom of the lamp body can flow through the heat-generating areas of the first LED light source 31 and the PCB driver board 3, and finally dissipate the heat from the lamp body heat dissipation shell 1 to the surrounding environment, ensuring that the lamp operates within the normal operating temperature range.

[0029] Furthermore, in this invention, the cooling fan 4 is embedded in the opening 32 of the PCB driver board 3 and located below the first LED light source component 31. This design allows the cooling fan 4 to directly dissipate heat from the first LED light source component 31 at close range, resulting in a short airflow path and high heat dissipation efficiency. Simultaneously, the cooling fan 4 is integrated with the PCB driver board 3. This integrated design fully utilizes the space of the PCB driver board 3, avoiding the cooling fan 4 occupying additional internal space of the lamp body. This makes the entire LED automotive lamp structure more compact, reducing the lamp body's size and facilitating installation and use in automobiles. It avoids the problem of low heat dissipation efficiency caused by excessively long airflow paths in traditional external fan solutions. Moreover, the design of the lamp body heat dissipation shell 1 is also simpler, avoiding the increased size caused by external heat dissipation devices.

[0030] Furthermore, in this invention, the light cup 5 can reflect and focus the light emitted by the first LED light source 31, so that the light is projected onto the lens 2 in a more concentrated and uniform manner. The lens 2 can then further adjust the direction and distribution of the light, thereby improving the lighting effect of the LED car light, making the light illumination range more reasonable and the brightness more uniform, improving driving safety, and better meeting the lighting needs of cars at night or in complex road conditions.

[0031] Furthermore, in this utility model, when installing the LED car light of this application, it is only necessary to insert the conductive plug 12 into the corresponding socket of the car to realize the connection between the LED car light and the car circuit. There is no need for complicated wiring operations, which makes the installation and maintenance of the LED car light more convenient and quick. It not only improves the installation efficiency and reduces the maintenance cost, but also reduces the risk of failure caused by improper installation.

[0032] Furthermore, in this embodiment, as Figure 2 , Figure 4 and Figure 6 As shown, the rectifier board 33 is located at the bottom of the PCB driver board 3. In automotive lamps, space is typically limited. This application places the rectifier board 33 at the bottom of the PCB driver board 3, which fully utilizes the space at the bottom of the lamp body, avoids interference with other components, makes the entire lamp body structure more compact, and improves space utilization. The bottom position also facilitates connection with the conductive plug 12 located at the bottom of the lamp body's heat dissipation housing 1, and also allows for easy docking with the pins at the bottom of the PCB driver board 3, making the wiring connection simpler and clearer, reducing the length and complexity of the wiring, and lowering the probability of failure due to wiring problems. The rectifier board 33 has a first slot 331 for inserting the pins of the conductive plug 12 for soldering and a second slot 332 for inserting the pins at the bottom of the PCB driver board 3 for soldering. In this application, the first slot 331 and the second slot 332 can respectively position and fix the conductive plug 12 and the pins of the PCB driver board 3. During the soldering process, the pins will not easily move, thus ensuring the soldering quality and making the connection more stable and reliable. Meanwhile, when soldering the pins, the operator only needs to accurately insert the conductive plug 12 and the pins of the PCB driver board 3 into the corresponding slots and then solder them. There is no need for complicated alignment and fixing operations, which improves the installation efficiency. When maintaining or replacing, it is also easier to remove the conductive plug 12 from the slot, which facilitates repair or replacement of new parts.

[0033] Furthermore, in this embodiment, as Figure 5 and Figure 6 As shown, a second LED light source 34 is provided on the rear end face of the PCB driver board 3. The second LED light source 34 can be independently controlled or work in conjunction with other components according to actual needs, providing a more comprehensive lighting effect and adapting to various complex driving environments. A second window 16 is provided on the heat dissipation housing 1 of the lamp body to expose the second LED light source 34. The opening 32 is also located below the second LED light source 34, so that the cooling fan 4 set in the opening 32 can directly blow air to dissipate heat from the second LED light source 34, allowing the heat to be dissipated quickly and ensuring that the second LED light source 34 operates at a suitable temperature.

[0034] Furthermore, in this embodiment, as Figure 4 and Figure 6 As shown, a heat pipe 35, located on one side of the cooling fan 4, is attached to the front or rear end face of the PCB driver board 3. The heat pipe 35 is typically filled with a working medium. During operation, the working medium absorbs heat at the evaporation end (closer to the heat source, i.e., the surface of the PCB driver board 3) and undergoes a phase change, changing from a liquid to a gaseous state. The gaseous working medium then rapidly flows through the heat pipe 35 to the condensation end (the end furthest from the heat source), releases heat at the condensation end, and then reverts to a liquid state, flowing back to the evaporation end under capillary force or gravity. This cycle repeats, achieving efficient heat transfer. This phase change heat transfer method gives the heat pipe 35 extremely high thermal conductivity, enabling it to conduct a large amount of heat away from the heat source in a short time. Simultaneously, the airflow generated by the cooling fan 4 provides the necessary conditions for heat dissipation from the heat pipe 35. As the airflow passes over the surface of the heat pipe 35, it carries away the heat released by the heat pipe 35, accelerating the phase change cycle inside the heat pipe 35 and further improving heat dissipation efficiency. By placing the heat pipe 35 on one side of the cooling fan 4, the airflow of the cooling fan 4 can be fully utilized to achieve the best heat dissipation effect.

[0035] Furthermore, in this embodiment, as Figure 2 , Figure 4 and Figure 6 As shown, the air outlet of the cooling fan 4 faces the first LED light source 31 and the second LED light source 34, allowing the airflow to directly act on the heat source, quickly removing heat and meeting the heat dissipation requirements of the LED light source. This ensures that the LED light source operates within a suitable temperature range, thereby guaranteeing its stable performance and providing reliable lighting for the vehicle. Alternatively, the air outlet of the cooling fan 4 faces the heat pipe 35, enhancing convective heat transfer on the heat pipe surface, accelerating heat dissipation, and enabling the heat pipe to operate continuously and efficiently, achieving efficient heat transfer and dissipation, and ensuring the stable operation of the entire cooling system. Or, the air outlet of the cooling fan 4 faces the first LED light source 31, the second LED light source 34, and the heat pipe 35, combining the advantages of the above two designs to provide a more comprehensive and efficient heat dissipation solution for LED automotive lights. On the one hand, it directly dissipates heat from the light source, reducing its temperature and ensuring its luminous performance and lifespan; on the other hand, it enhances the heat dissipation effect of the heat pipe, optimizes the overall heat dissipation cycle, improves the efficiency of the entire cooling system, and ensures that the LED automotive lights can operate stably and reliably under various operating conditions.

[0036] Furthermore, in this embodiment, as Figure 4 and Figure 6As shown, a detachable light-blocking strip 6 is provided on the first window 11 above the light outlet of the reflector cup 5. This light-blocking strip 6 can be either a left or right light-blocking strip. The design and size of these two light-blocking strips may differ slightly to accommodate driving habits in different countries or regions, i.e., whether the steering wheel is located on the left or right side of the vehicle. The specific light-blocking strip used depends on the position of the steering wheel. When the car is designed for left-hand drive (with the steering wheel on the right), a left light-blocking strip should be installed to ensure that light does not directly illuminate the driver of oncoming vehicles, thereby reducing glare and improving road safety. Conversely, when the car is designed for right-hand drive (with the steering wheel on the left), a right light-blocking strip should be installed to achieve the same safety purpose. This application provides both left and right light-blocking strips, a design that can adapt to driving habits in different countries and regions, regardless of whether it is left-hand or right-hand drive. Furthermore, the detachable design of the light-blocking strip 6 makes maintenance and replacement simple and quick, requiring no special tools or complex operations. Users can easily replace the light-blocking strip as needed, improving product flexibility and user satisfaction. With this design, LED automotive lights can better adapt to the needs of different markets, while ensuring a safe and comfortable lighting experience under various driving conditions.

[0037] Furthermore, in this embodiment, as Figure 2 , Figure 4 and Figure 6 As shown, the lamp body heat dissipation housing 1 includes a first housing body 13 and a second housing body 14 that are configured to be fitted together. The length of the first housing body 13 is shorter than that of the second housing body 14. This design allows for a reasonable layout based on the size and shape of the internal components. For example, a longer component (such as the PCB driver board 3) can be placed in the second housing body 14, while the shorter first housing body 13 is placed on top, making full use of the internal space of the lamp body and making the structure more compact. A first window 11 is formed between the top end of the first housing body 13 and the top end of the second housing body 14. The top end of the second housing body 14 is provided with a lens fixing member 141 for fixing the lens 2 therein, to ensure that the installation position of the lens 2 is accurate and can be stably fixed.

[0038] Alternatively, the lamp body heat dissipation housing 1 includes a first housing body 13 and a second housing body 14 that are left and right overlapping each other. A lens fixing member 141 is formed between the top ends of the first housing body 13 and the second housing body 14, and a first window 11 is located below the lens fixing member 141. In this utility model, the first housing body 13 and the second housing body 14 are assembled together by overlapping, making the assembly process of the LED automotive lamp simpler. During the production process, workers can install each component onto the first housing body 13 and the second housing body 14 separately, and then close them together, reducing the complexity and difficulty of assembly. At the same time, in the later maintenance or replacement of components, only the two housing bodies need to be opened to easily operate the internal components, improving maintenance efficiency and reducing maintenance costs.

[0039] Furthermore, in this embodiment, as Figure 4 and Figure 6 As shown, the cooling fan 4 includes a fan mounting bracket 41 fixed inside the opening 32. The fan mounting bracket 41 houses the main fan component 42. The inwardly protruding design of the fan mounting bracket 41 more effectively utilizes the space at the rear end of the lamp body heat dissipation housing 1, providing sufficient installation space for the main fan component 42. It also ensures that the airflow of the fan can smoothly pass through the lamp body heat dissipation housing 1, improving heat dissipation efficiency. Ventilation openings 43 are provided around the top of the fan mounting bracket 41, communicating with the interior of the lamp body heat dissipation housing 1. This allows the cool air drawn in by the main fan component 42 to directly act on the lamp body heat dissipation housing 1, while simultaneously promoting airflow inside the lamp body heat dissipation housing 1 and improving the heat dissipation effect.

[0040] Furthermore, in this embodiment, as Figures 1-6 As shown, the lamp body heat dissipation shell 1 has several slots 15 that penetrate the interior of the lamp body heat dissipation shell 1, allowing air to flow more freely between the inside and outside of the lamp body. When the cooling fan 4 is working, external air can enter the lamp body through the slots 15, carrying away the heat generated by internal components (such as the PCB driver board and LED light source components), and then exhausting from the slots 15 on the other side, forming a good air convection circulation and greatly improving heat dissipation efficiency. For example, without slots, airflow is restricted, and heat easily accumulates inside the lamp body; with slots, air can quickly enter and exit, carrying away heat in time, just like installing a "ventilation duct" for the lamp body.

[0041] Furthermore, in this embodiment, as Figures 1-6As shown, a chuck 7 is fixedly connected to the headlight assembly and fitted onto the lamp body heat dissipation housing 1. The chuck 7 is an integrated or split structure formed by die casting or extrusion. Integrated molding reduces processing steps and assembly stages in the production process, improving production efficiency and reducing production costs. Simultaneously, reducing the use of connecting parts also lowers maintenance costs due to loosening or damage to connections. For some complex-shaped or large-sized chucks 7, a split structure reduces manufacturing difficulty; the chuck 7 can be disassembled into multiple smaller parts for separate manufacturing and then assembled, improving manufacturing feasibility and quality. During installation, simply fit the lamp body heat dissipation housing 1 into the chuck 7 and connect the chuck 7 to the headlight assembly using appropriate fixing methods (such as bolt fixing, clip fixing, etc.). This installation method does not require complex tools or operating procedures, improving installation efficiency. When maintenance or replacement of the LED automotive light is required, the design of the chuck 7 allows for easy removal of the lamp body heat dissipation housing 1 from the chuck for necessary inspection, repair, or replacement of parts. After the operation is completed, the heat dissipation shell 1 of the lamp body is put back into the chuck 7 and fixed in place, and it can be put back into use, which reduces the difficulty and cost of maintenance.

[0042] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
