Description

Technical Field

[0001] This utility model relates to the field of LED vehicle lighting technology, specifically an integrated LED bracket vehicle lighting system. Background Technology

[0002] With the continuous development of automotive lighting technology, LED headlights have gradually replaced traditional halogen lamps and xenon lamps and become the mainstream headlight configuration due to their advantages such as high brightness, low energy consumption and long life.

[0003] In existing technologies, LED automotive lights typically adopt a split structure, mainly including components such as a base plate, circuit board, LED light source, power module, and antenna.

[0004] The circuit board needs to be soldered onto the base plate first, and then connected to the power module by soldering or plugging. The contacts also need to be soldered separately onto the power module or circuit board.

[0005] This structure has the following problems: First, the assembly process is complex, requiring multiple welding and assembly processes, resulting in low production efficiency and high cost. Secondly, the numerous welding points make it prone to problems such as incomplete welding and poor contact, affecting the reliability and lifespan of the headlights; Secondly, the heat dissipation path of the split structure is not continuous, and the heat generated by the LED during operation is difficult to dissipate quickly, which can easily lead to accelerated light decay. In addition, the existing headlight structure is large in size, which is not conducive to its placement in a compact headlight space, and its installation and maintenance are also relatively inconvenient.

[0006] Therefore, the industry urgently needs an integrated LED vehicle light structure that is simplified, has good heat dissipation, is easy to install, and has high reliability in order to improve product performance and reduce manufacturing costs. Summary of the Invention

[0007] The purpose of this invention is to provide an integrated LED bracket vehicle light to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: Integrated LED bracket car light, including: The support circuit is a one-piece conductive structure having a substrate portion and at least two extension portions; At least one LED light is disposed on the substrate and electrically connected to the bracket circuit; At least two tentacles are respectively located at the ends of the extension and are integrally formed with the bracket circuit; The power module is located on the bracket circuit and is electrically connected to the LED light and the contact point through the bracket circuit. Several groups of LED lights are folded and attached to the outside of the power module through the bracket circuit.

[0009] In a preferred embodiment of this utility model, the antennae are integrally bent and formed with the extension of the bracket circuit for electrical connection with an external power supply and a controller.

[0010] In a preferred embodiment of this utility model, the LED lamp includes LED beads and an LED lamp holder, and the LED lamp holder is fixedly connected to the substrate portion of the bracket circuit.

[0011] In a preferred embodiment of this utility model, a heat-conducting layer is provided on the surface of the bracket circuit, and the heat-conducting layer is in contact with the back of the LED lamp.

[0012] In a preferred embodiment of the present invention, a housing is further included, on which a support circuit and a power module are fixedly mounted, and the tentacles extend out of the housing.

[0013] In a preferred embodiment of this utility model, the power module includes a voltage regulator circuit and a terminal block, the terminal block being used to connect an external power source and a control signal line.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0015] Simplified structure and high integration: By using a one-piece molded bracket circuit to replace the traditional base plate and discrete circuit board, the LED lights, power modules and contacts are directly integrated on the bracket circuit, reducing the number of parts and welding processes, greatly simplifying the assembly process, improving production efficiency and reducing production costs.

[0016] Reliable electrical connections: The one-piece molded structure avoids problems such as poor contact and incomplete welding caused by multi-section welding, improves the stability and reliability of electrical connections, and extends the service life of vehicle lights.

[0017] Excellent heat dissipation performance: The bracket circuit is made of a metal material with good thermal conductivity and is in direct contact with the back of the LED lamp to form a continuous heat dissipation path. It can quickly conduct the heat generated by the LED to the housing for dissipation, effectively reduce the operating temperature, delay light decay, and improve the lighting effect and lifespan.

[0018] Easy installation and maintenance: The overall modular design makes the headlight structure compact, which is convenient for installation and fixation in limited space; the antennas extend directly out of the housing, which facilitates quick docking with external power supplies and controllers, simplifies the wiring process, and also facilitates later maintenance and replacement.

[0019] Highly adaptable and expandable: The bracket circuit can be flexibly designed in shape and size according to different vehicle models and installation requirements. The power module supports external power supply and controller, is compatible with multiple voltage and signal control methods, and is suitable for various vehicle lighting scenarios.

[0020] Environmental protection and energy saving: The use of welding materials and auxiliary structures is reduced, which is in line with the trend of green manufacturing; LEDs themselves have high energy efficiency characteristics, and combined with excellent heat dissipation design, the overall energy efficiency ratio is further improved.
