Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fog light technology, specifically relating to a modular LED fog light. Background Technology
[0002] Currently, with the widespread use of automobiles and the continuous development of science and technology, the performance of various automotive components is constantly being improved. Car fog lights (used to illuminate the road in rainy or foggy weather), as an important lighting fixture for safe driving, are also among the areas targeted for improvement. Judging from existing car fog lights, there is still considerable room for improvement. Although existing car fog lights generally improve the driver's visibility in foggy weather and have strong penetrating power, they mostly still use traditional light sources such as halogen lamps. These are not only energy-intensive and environmentally unfriendly, but more seriously, they have a short lifespan and require frequent replacement, causing inconvenience to users.
[0003] Chinese Patent Application No. 2019212719907 discloses a full LED fog light, which includes a lamp holder housing; a fog light circuit board built into the lamp holder housing, the fog light circuit board having a fog light LED bead located in the center, a support sleeve that is screwed through the fog light circuit board and fixed to the bottom of the lamp holder housing, the support sleeve exposing the fog light LED bead, a lens covering the support sleeve and corresponding to the fog light LED bead, and the lens being fixed by a limiting frame, a position light circuit board that is circumferentially arranged around the limiting frame, the position light circuit board being annular and having multiple position light LED beads in a circumferential array, an annular light guide plate that is fixed by screws and covers the position light circuit board, and a lamp cover covering the lamp holder housing.
[0004] The above solution has the advantages of saving resources and being environmentally friendly. However, it uses a lot of parts, making maintenance more complicated. If any part is damaged, the entire fog light assembly may need to be replaced, rather than just a single part, which increases the cost of repair and maintenance. Utility Model Content

[0006] Preferably, the edge of the outer casing has an extension groove that extends vertically through it, the extension groove being connected to a heat dissipation channel, one side of the cover plate being hinged to one side of the outer casing, the other end of the cover plate covering the side of the outer casing, and a locking device being provided between the end of the cover plate and the side of the outer casing.
[0007] Preferably, the locking device includes a locking assembly disposed within the end of the cover plate and a hook groove disposed on the side of the outer casing. The locking assembly includes a rotating plate rotatably disposed on the side wall inside the end of the cover plate. A locking rod is fixedly connected to one side of the rotating plate. A locking hook is connected to the end of the locking rod. The locking hook cooperates with the hook groove. A spring and a pressing rod are respectively provided on the two ends of the rotating plate opposite to the locking rod. The other end of the spring is connected to the side wall inside the end of the cover plate.
[0008] Preferably, the front end of the outer casing is provided with a protective groove, a protective plate is hinged above the protective groove, and the interface is located inside the protective groove.
[0009] Preferably, the surface of the outer casing is also provided with buttons.
[0010] The advantages of this utility model are:
[0011] 1. Each module in this solution can be replaced independently. If a module malfunctions or needs upgrading, the entire fog light system does not need to be replaced, thus reducing maintenance costs. At the same time, the modular design simplifies the assembly process, reduces manual assembly time, and improves production efficiency.
[0012] 2. The design of the ring-shaped reflector array in this scheme allows light to be reflected progressively from the center of the LED light source module outwards. Each layer of reflectors reflects and gradually focuses the light, ensuring that the light achieves the desired illumination effect at the final lens module. This layered design improves the focusing efficiency of the light, ensuring the quality and intensity of the beam.
[0013] 3. In this design, the heat sink module consists of several equally spaced heat sinks. The design of the heat sinks increases the heat dissipation surface area, which helps to dissipate the heat generated by the LED light source module into the air more quickly. This helps to reduce the overheating problem of the LED light source module and ensure its long-term stable operation. Attached Figure Description

[0022] Example 1, as Figure 1-4As shown, a modular LED fog light includes a housing module 1, a lens module 2, an LED light source module 3, and a heat sink module 4. The LED light source module 3 is connected to the front end of the housing module 1, the lens module 2 is sleeved on the front end of the housing module 1, and the heat sink module 4 is connected to the rear side of the housing module 1. The housing module 1 includes a substrate 5, with a front extension 6 and a rear extension 7 on its front and rear sides, respectively. The LED light source module 3 is connected to the front extension 6. The lens module 2 includes a connecting frame 8 and a concave-convex optical lens 9 disposed at the front end of the frame. The rear end of the connecting frame 8 is engaged with the outer edge of the front extension 6, and the optical lens 9 covers the front end of the LED light source module 3. The light emitted by the LED light source module 3 passes through the optical lens 9 and is transmitted forward. The housing module 1, lens module 2, LED light source module 3, and heat sink module 4 can all be replaced independently. If any module malfunctions or needs to be upgraded, such as replacing the LED light source module 3, the entire fog light system does not need to be replaced, thereby reducing maintenance costs. The heat sink module 4 is independently located at the rear of the housing module 1, ensuring that the LED light source module 3 will not overheat during prolonged use, thus extending the lifespan of the LED beads. Through modular design, the selection and replacement of the heat sink module are more flexible; modules with stronger heat dissipation performance can be selected based on actual usage, improving the overall reliability of the lighting fixture. The mirror module uses a concave-convex optical lens 9, which can better focus and guide light, improving luminous efficiency and illumination range. This optical lens 9 design allows for precise control of the beam direction and distribution, enhancing the fog light's illumination effect and improving vehicle visibility in foggy or hazy weather.
[0023] Combination Figure 1 and Figure 4 The side of the connecting frame 8 has a hook hole 10, and the side of the front extension 6 has an elastic hook block 11, which is snapped into the hook hole 10. Through the snap-fit design of the elastic hook block 11 and the hook hole 10, the installation and removal of the lens module 2 and the housing module 1 become very simple, requiring no additional tools or complicated operations.
[0024] Combination Figure 1The LED light source module 3 is surrounded by a ring-shaped reflector group, which includes a first ring-shaped reflector 12, a second ring-shaped reflector 13, and a third ring-shaped reflector 14. These three reflectors are three concentric circles with progressively increasing diameters and thicknesses. This ring-shaped reflector group design allows light to be reflected gradually from the center of the LED light source module 3 outwards. Each layer of reflectors reflects and gradually focuses the light, ensuring that the light achieves the desired illumination effect at the final lens module 2. This layered design improves light focusing efficiency and ensures the quality and intensity of the light beam. Simultaneously, by progressively guiding the light through multiple ring-shaped reflectors, light scattering and waste are effectively reduced, avoiding unnecessary light scattering and light pollution, and improving the overall luminous efficacy of the LED light source. As the diameter and thickness of the reflectors gradually increase, they can handle a wider range of light, ensuring that light loss during reflection is minimized. Each time light passes through a reflector, it is better guided, increasing reflection efficiency and thus improving the final illumination effect. In this embodiment, there are three LED light source modules 3 in total, one above the other, and each LED light source module 3 is surrounded by a ring-shaped reflector group.
[0025] Combination Figure 1 The substrate 5 has heat dissipation slots 15 on its side, and the heat sink module 4 is connected to the rear extension 7. The heat sink consists of several heat sink fins with equal spacing. The design of the heat sink increases the heat dissipation surface area, which helps to dissipate the heat generated by the LED light source module 3 into the air more quickly. This helps to reduce the overheating problem of the LED light source module 3 and ensure its long-term stable operation. Through the reasonable spacing of the heat sink fins, airflow is enhanced and the heat dissipation effect is optimized. The design of the heat dissipation slots 15 can guide airflow and carry away heat through natural convection, improving the overall heat dissipation efficiency.
[0026] Combination Figure 3The system also includes connecting bolts 16, threaded grooves 17 on the upper and lower sides of the base plate 5, and a mounting plate 18 on the side of the lens module 2. The mounting plate 18 has threaded holes on its upper and lower sides. The connecting bolts 16 pass through the threaded grooves 17 and enter the threaded holes to fix the base plate 5. The connecting bolts 16 are locked into the threaded holes, and their shanks lock the base plate 5 onto the mounting plate 18. The mounting plate 18 is also a frame structure, fixed to the position where the fog lights are placed on the vehicle. The entire fog light module can be quickly fixed by tightening the connecting bolts 16. A connector is provided on the rear extension 7, enabling electrical connection between the vehicle's power supply and the LED light source module 3. When the LED light source module 3 is powered on, it emits light from the front end of the lens module 2 and the mounting plate 18. By using bolts and the mounting plate 18, the entire fog light module can be easily disassembled and replaced. If repair or upgrades to the LED light source module 3, lens module 2, or other components are needed, simply unlocking the bolts allows for quick disassembly or replacement without disassembling the entire system. This modular design not only improves the system's flexibility but also simplifies maintenance.
