[0036] The copper plate 11 is made of high-purity red copper, which has excellent electrical conductivity and thermal conductivity. Its shape is designed according to the layout of the lamp beads 2 and other components, generally flat, with pads on the surface for welding the lamp beads 2 and the control reaction electronic element 12. The surface of the pads is treated specially, such as tin plating, to improve the reliability and electrical conductivity of the welding. The thickness of the copper plate is moderate, which can ensure good electrical conductivity and mechanical strength, prevent deformation during installation and use, and help to quickly conduct the heat generated by the lamp beads 2, ensuring the stable operation of the lamp beads 2.

[0037] The control reaction electronic element 12 is a circuit board integrated with multiple electronic chips and components. The core driving chip is responsible for accurately adjusting the size and frequency of the input current, and through the control of the current, it realizes precise control of the brightness and color temperature of the lamp beads 2. For example, during night driving, the brightness of the lamp beads 2 can be automatically adjusted according to the change of environmental light to provide the best lighting effect. At the same time, it can also adjust the color temperature of the light according to different driving scenes, such as expressway, urban road, etc., to make the driver's vision more comfortable. In addition to the driving chip, the circuit board also integrates capacitors, resistors and other components. The capacitor is used for filtering and stabilizing voltage to prevent current fluctuations from damaging the lamp beads 2. The resistor plays a role in current limiting and voltage dividing to ensure that each electronic component works under appropriate voltage and current conditions.

[0039] Radiator 6: The radiator 6 is usually made of aluminum alloy, which takes advantage of the good thermal conductivity and heat dissipation of aluminum alloy. It is mainly composed of heat dissipation fins and a base. The heat dissipation fins are the key heat dissipation components of the radiator, which are thin and numerous and closely arranged. The shape of the fins is usually flat, with a large surface area, which can increase the contact area with air and improve the heat dissipation efficiency. The spacing of the fins is carefully designed to ensure sufficient air flow space and to ensure that the fins do not affect the overall heat dissipation effect due to excessive spacing. The base is in close contact with the light emitting device 10 and is usually designed as a flat surface to ensure good adhesion to the light emitting device 10, which can efficiently absorb the heat generated by the light emitting device 10. In order to further improve the heat dissipation efficiency, the radiator 6 may be equipped with high-efficiency heat dissipation structures such as heat pipes or heat plates inside. The heat pipe is sealed and contains a special working medium. When one end is heated, the working medium evaporates and transfers heat to the other end, releasing heat through condensation to achieve efficient heat conduction. The heat plate can evenly distribute heat on the entire plate surface, improving the uniformity of heat dissipation. The shape and size of the radiator 6 are adapted to the internal space of the lamp, and it is fixed in the heat dissipation mounting groove 16 of the bottom plastic housing bottom plate 5 by screws or buckles, etc. to ensure stable installation.

The number of layers of the PCB board 7 is determined according to the functional requirements of the lamp, which is usually double or multi-layer. In the design, the layout and wiring of the circuit are fully considered to reduce signal interference and current loss.

The fan blade is made of plastic or metal material. The plastic fan blade has the characteristics of light weight and low cost. The metal fan blade has higher strength and durability. The shape and angle of the fan blade are optimized by aerodynamics. Common designs include three-leaf, four-leaf or multi-leaf designs. The angle design of the fan blade can generate a large amount of air under the driving of the motor, and quickly blow the external cold air to the radiator 6. The fan shell protects the motor and fan blade, and at the same time guides the airflow to the radiator 6. The shell is generally made of plastic material. Its shape is designed according to the structure of the radiator 6 and the internal space of the lamp, to ensure that the airflow can pass through the radiator 6 evenly, improving the heat dissipation effect;

[0042] Waterproof rubber ring 1: The waterproof rubber ring 1 is generally made of silicone rubber or ethylene-propylene-diene rubber, which has excellent weather resistance, elasticity and anti-aging performance. The waterproof rubber ring 1 is annular, and its cross-sectional shape is commonly circular or rectangular;

[0043] Fixed connection assembly: The fixed connection assembly is composed of a fixed connection screw 3 and a screw connection table 14. The fixed connection screw 3 is usually made of high-strength metal material, such as stainless steel, to ensure that it is not easily deformed or broken under frequent use. The screw head is generally designed as a cross slot or hexagonal shape, which facilitates the use of a screwdriver or wrench for operation. The screw rod part has standard threads, and its pitch, angle, etc. are accurately designed to ensure tight matching with the thread groove on the screw connection table 14, providing reliable fastening force when tightened;

[0044] Screw connection table 14: The screw connection table 14 is a block structure fixed to the inner front bottom surface of the bottom plastic shell bottom plate 5, and is made of the same material as the bottom plastic shell bottom plate to ensure structural compatibility. The thread groove on the top surface is calculated strictly to ensure that the screw is screwed in deep enough to make the connection stable, and not too deep to weaken the structural strength of the bottom plastic shell bottom plate. The high precision of the thread groove tightly matches the threads of the fixed connection screw 3, effectively preventing the screw from loosening under vibration and other conditions, and ensuring the reliable connection of the top plastic shell cover plate 4 and the bottom plastic shell bottom plate 5;
