Description
Technical Field
[0001] This utility model relates to the field of automotive lighting technology, and in particular to a fog light for automobiles. Background Technology
[0002] Automotive fog lights are functional lights specifically designed to cope with low visibility weather conditions such as rain, fog, snow, and sandstorms in automotive lighting systems. They are a key auxiliary equipment for safe driving. Their core function is to emit light with strong penetrating power, providing short-range road illumination for the vehicle itself, helping the driver clearly identify the road outline, obstacles, and markings ahead. Simultaneously, they significantly improve the vehicle's visibility, allowing other vehicles and pedestrians to spot it in time, thereby effectively reducing the risk of rear-end collisions, scrapes, and other traffic accidents in low-visibility environments, and ensuring driving safety.
[0003] Currently, automotive front fog lights are typically mounted low on the sides of the bumper or grille, while rear fog lights are often integrated into the taillights or positioned separately at the bottom of the bumper. The overall mounting position is generally low to accommodate their close-range, wide-angle illumination needs. However, because the current fog lights are installed close to the curved areas of the vehicle body, the light-emitting area is easily obstructed by the body structure, resulting in insufficient light diffusion and limited illumination range. In dense fog or heavy rain, drivers may still face significant blind spots. Furthermore, existing fog lights have poor heat dissipation, which can shorten their lifespan.
[0004] Therefore, there is an urgent need to design a fog light for automobiles that can significantly widen the illumination area of the light source, effectively eliminate the blind spots caused by the obstruction of the vehicle body in traditional fog lights, further improve the visibility of vehicles in low visibility environments, reduce the incidence of traffic accidents caused by limited visibility, and thus effectively improve the safety and stability of vehicles in adverse weather conditions. In addition, the structure is simple and compact, the heat dissipation effect is good, the stability of fog light operation is effectively improved, and the service life is extended.

[0023] Currently, automotive front fog lights are typically installed in a low position below the vehicle's bumper or on either side of the grille, while rear fog lights are mostly integrated into the taillight assembly or installed separately at the bottom of the bumper. The overall installation position is generally low to accommodate the vehicle's close-range, wide-angle lighting needs. However, because the current fog lights are installed close to the curved areas of the vehicle body, the light-emitting area is easily obstructed by the body structure, resulting in insufficient light diffusion and limited illumination range. In dense fog or heavy rain, drivers may still face the problem of excessively large blind spots.
[0024] To address the aforementioned problems, this application provides an automotive fog light that significantly widens the illumination area of the light source, effectively eliminating blind spots caused by the vehicle body blocking the light from traditional fog lights. This further enhances vehicle visibility in low-visibility environments, reduces the incidence of traffic accidents caused by limited visibility, and effectively improves vehicle safety and stability in adverse weather conditions. Furthermore, the fog light has a simple and compact structure, excellent heat dissipation, and effectively improves operational stability and extends its service life. The technical solution of this application embodiment is described in detail below with reference to the accompanying drawings. Example
[0025] Please see Figures 1-7 The automotive fog light of this application includes a housing 1, a mounting bracket 2, a first light source assembly 3, and a second light source assembly 4. The housing 1, serving as the external protective structure of the entire fog light, is made of high-strength, corrosion-resistant engineering plastic, providing excellent protection while effectively reducing the overall weight of the fog light. The mounting bracket 2 is disposed within the housing 1 and is stepped in shape. Specifically, the mounting bracket 2 includes a first mounting step 21 and a second mounting step 22 arranged sequentially, with the first mounting step 21 being higher than the second mounting step 22. The first light source assembly 3 is disposed on the first mounting step 21 and protrudes from the housing opening 11, while the second light source assembly 4 is disposed on the second mounting step 22 and protrudes from the housing opening 11. For example, one end of the housing 1 has a housing opening 11, which is an inclined surface, meaning one end of the housing opening 11 is higher than the other end, facilitating adaptation to the shape of the vehicle body. The first mounting step 21 and the second step are arranged sequentially from high to low along the opening 11 of the housing, so that both the first light source assembly 3 and the second light source assembly 4 can protrude from the opening 11 of the housing. By setting the first light source assembly 3 and the second light source assembly 4 at different heights, a vertically distributed light-emitting area is formed, effectively widening the illumination range of the light source 32 and avoiding the problem of light emitted by traditional fog lights being blocked by the vehicle body structure. This effectively expands the illumination area and reduces the incidence of traffic accidents caused by limited visibility.
[0026] Furthermore, both the first light source assembly 3 and the second light source assembly 4 include a light source fixing plate 31, a light source 32, a lens bracket 33, and a lens 34. The light source fixing plate 31 is fixed on the first mounting step 21 and the second mounting step 22, respectively, and is located inside the lens bracket 33, providing a stable mounting base for the light source 32. The light source 32 is mounted on the light source fixing plate 31, and its light emission direction faces the housing opening 11, ensuring that the light can be emitted directly without being blocked by the internal structure. One end of the lens bracket 33 is fixed on the first mounting step 21 and the second mounting step 22, respectively, and the other end has an opening 331 for mounting the lens 34 and guiding the light to be emitted, so that the light emitted by the light source 32 located inside the lens bracket 33 can be emitted from the opening 331. The lens 34 is mounted on the lens bracket 33 and is located at the opening 331 and protrudes from the opening 331 and the housing opening 11. It is used to focus and refract the light emitted by the light source 32, further optimizing the propagation direction and illumination effect of the light, making the light more concentrated and covering a wider range, and improving the utilization rate and illumination intensity of the light source 32.
[0027] Furthermore, to improve the sealing and protective performance of the fog light, a base 12 is provided inside the housing 1. The base 12 is located at the bottom of the housing 1 and is integrally connected to the housing 1, providing a relatively sealed environment for the first light source assembly 3 and the second light source assembly 4. The mounting bracket 2 is mounted on the base 12 to ensure that the mounting bracket 2 is installed firmly and reliably. Further, to prevent dust, moisture, and other impurities from entering the fog light and affecting the normal operation of the first light source assembly 3 and the second light source assembly 4, the automotive fog light also includes a face shield 5. An annular groove 13 is provided at the opening 11 of the housing, and the face shield 5 is inserted into the annular groove 13. The face shield 5 is made of a transparent material, such as high-transmittance glass or plastic, ensuring that light can pass smoothly through the face shield 5 and protect the internal first light source assembly 3 and the second light source assembly 4 from damage by the external environment. Furthermore, in order to enhance the sealing between the face shield 5 and the housing 1, the automotive fog light also includes a sealing ring, which is disposed in the annular groove 13 to achieve a tight fit between the face shield 5 and the housing 1, effectively preventing external moisture and dust from entering the fog light and improving the service life and reliability of the fog light.
[0028] To dissipate the heat generated by the first light source assembly 3 and the second light source assembly 4 in a timely manner, the automotive fog light also includes several heat dissipation fins 6. These fins 6 are arranged parallel to each other at the bottom end of the housing 1 and connected to the base 12, integrally formed with the housing 1, effectively increasing the heat dissipation area and improving heat dissipation efficiency. Furthermore, a gap is provided between any two adjacent heat dissipation fins 6 to facilitate airflow and further enhance the heat dissipation effect. In addition, the automotive fog light also includes a heat dissipation guide post 7, which is inserted into the base 12. One end of the heat dissipation guide post 7 extends towards the housing opening 11, and the other end is connected to the heat dissipation fins 6. This guide post is used to quickly conduct the heat generated by the first light source assembly 3 and the second light source assembly 4 to the heat dissipation fins 6, and then dissipate it through the heat dissipation fins 6, ensuring that the fog light maintains stable performance even during prolonged operation. Furthermore, to further improve the heat dissipation effect, the automotive fog light also includes a cooling fan 8, which is located at the bottom end of the heat dissipation fins 6 and fixed to them with screws. When the fog lights are in use, the cooling fan 8 is activated to accelerate airflow, thereby further improving heat dissipation efficiency and ensuring that the fog lights are always in good working condition.
[0029] To facilitate the fixing of the entire automotive fog light to the vehicle body, the automotive fog light also includes a mounting base 9, which is sleeved on the housing 1 and connected to the heat dissipation fins 6. The mounting base 9 is provided with mounting screw holes, and screws are passed through these holes to fix the mounting base 9 to the vehicle body. This securely fixes the fog light to the vehicle body, ensuring it will not loosen or fall off due to vibration during driving.
[0030] It should be noted that the circuit control components of the automotive fog lights are existing technology and will not be described in detail here.
[0031] Working principle: When a car is driving in low-visibility conditions, the fog lights of this application are activated, and the first light source assembly 3 and the second light source assembly 4 emit light simultaneously. Since the first light source assembly 3 and the second light source assembly 4 are at different heights, they form vertically distributed light-emitting areas. Light can pass through the cover 5 from the housing opening 11, effectively widening the illumination range of the light source 32 and avoiding the problem of light emitted by traditional fog lights being blocked by the vehicle body structure, further eliminating blind spots. Simultaneously, the lens 34 focuses and refracts the light emitted by the light source 32, making the light more concentrated and covering a wider area, improving the utilization rate and illumination intensity of the light source 32. Furthermore, during fog light operation, the heat generated by the first light source assembly 3 and the second light source assembly 4 is quickly conducted to the heat dissipation fins 6 through the heat dissipation guide pillars 7, and then dissipated into the air through the heat dissipation fins 6. At the same time, the cooling fan 8 is activated to accelerate airflow, further improving heat dissipation efficiency and ensuring that the fog lights are always in good working condition.
[0032] In this embodiment, the automotive fog light provided by this application includes a housing, a mounting bracket, a first light source assembly, and a second light source assembly. By positioning the first and second light source assemblies at different heights, a vertically distributed light-emitting area is formed. Furthermore, by positioning the first and second light source assemblies protruding from the opening in the housing, the illumination range of the light source is effectively widened, avoiding the problem of traditional fog light beams being blocked by the vehicle body structure, eliminating blind spots, and reducing the incidence of traffic accidents caused by limited visibility. Simultaneously, the lens focuses and refracts the light emitted by the light source, making the light more concentrated and covering a wider area, improving the utilization rate of the light source and the illumination intensity. By incorporating cooperating heat dissipation fins, heat dissipation guide pillars, and a cooling fan, the heat generated by the first and second light source assemblies can be dissipated in a timely manner, ensuring stable operation of the fog light for extended periods and extending its service life. The mounting base securely fixes the entire automotive fog light to the vehicle body, preventing it from loosening or falling off due to vibration during driving.
