[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0028] See Figures 1 to 4 As shown, a motorcycle lighting structure includes a PCB board 7 and an aluminum alloy housing 8. The aluminum alloy housing has a mounting cavity 9, and at least one limiting groove 10 is provided on the inner wall of the mounting cavity. Limiting protrusions 11 are integrally formed along the edge of the PCB board. The PCB board is located within the aluminum alloy housing, and the limiting protrusions are engaged in the limiting grooves. Heat from the PCB board is dissipated through the aluminum alloy housing. The aluminum alloy housing has limiting grooves at the top and bottom, whose shapes precisely match the limiting protrusions on the PCB board, ensuring that the PCB board can be completely and securely embedded within the aluminum alloy components, enhancing overall mechanical stability while expanding the heat dissipation area. The aluminum alloy components, acting as the housing, not only provide physical protection for the PCB board but also play a crucial role in heat dissipation. When the light is working, heat is conducted from the PCB board to the aluminum substrate and then seamlessly transferred to the aluminum alloy housing. Thanks to the excellent thermal conductivity and heat dissipation properties of aluminum alloy, heat is efficiently dissipated to the surrounding environment, maintaining the various components of the light within a suitable temperature range and extending its service life.
[0029] In this embodiment, the PCB board includes a substrate 6 and a driving circuit disposed on the substrate. The driving circuit includes a power input terminal 1, an integrated controller 2 connected to the power input terminal, a current detection circuit 3 connected to the integrated controller, and a multi-channel lamp control circuit 4 connected to the integrated controller. In practical applications, the integrated controller includes a main chip that is a four-level power-down switching chip and several MOS switches connected to the four-level power-down switching chip. The multi-channel lamp control circuit includes a red light control circuit, a white light control circuit, and a yellow light control circuit. The red light control circuit, white light control circuit, and yellow light control circuit are respectively connected to different MOS switches. The four-level power-down switching chip receives and processes signals from the current detection circuit and controls the switching of different lamps through different MOS switches. The model of the four-level power-down switching chip is XL-6280A. The detection element of the current detection circuit is a resistor. It can switch between different lamps according to different currents based on the detected circuit conditions, thereby ensuring the effectiveness and stability of intelligent switching, improving the lighting effect, and expanding its applicability. In this embodiment, the red light serves as a daytime running light, the yellow light provides low-beam illumination in rainy or foggy weather, and the white light provides high-beam illumination at night; these three colors can be freely switched. An integrated microcontroller with pre-programmed logic enables precise control of the lighting modes. In daytime running light mode, the MCU regulates the circuitry to keep the red light dimly lit, effectively marking the vehicle's location during the day while reducing power consumption. In low-beam mode, the yellow light is activated; this yellow light, optically optimized, possesses strong penetrating power in rainy or foggy weather, providing the rider with a clear view of nearby objects. Switching to high-beam mode activates the white light source, providing strong illumination over long distances.
[0030] Furthermore, the substrate is a 1.6mm thick PCB board. The substrate is also circular, with a C-shaped recessed groove 5 along its edge. This structure improves the effectiveness of switching control. The 1.6mm thick aluminum alloy PCB board provides good insulation and a certain degree of flexibility, offering a stable substrate for circuit layout. The upper aluminum substrate is tightly bonded, utilizing the high thermal conductivity of aluminum to quickly dissipate the heat generated by the electronic components.
[0031] This utility model has positive effects: The structure of this utility model is reasonable. It is equipped with an aluminum alloy shell, which not only has good insulation and flexibility, but also effectively stabilizes the PCB board. The PCB board can also dissipate heat through the aluminum alloy shell.
