Description

Technical Field

[0001] This utility model belongs to the field of automotive lighting technology, specifically relating to a novel fog light lens. Background Technology

[0002] Fog lights are essential safety lighting devices for automobiles in low-visibility weather conditions such as rain, snow, and fog. Their core design requirement is to provide a wide, straight beam with good penetration and without glare. Traditional fog lights mostly use a single reflector cup with a single light source and a lens with fixed light distribution. They have limited functionality, poor beam pattern adjustability, and cannot meet the needs of both wide-area illumination at close range and penetrating illumination at long distances.

[0003] With the development of automotive lighting technology, fog lights using bi-xenon lenses have emerged, capable of switching between high and low beams. However, existing bi-xenon fog light lenses typically have a relatively simple structure and limited beam pattern variation, making it difficult to simultaneously achieve optimal uniformity of the low beam spot and the range and width of the high beam. Especially in complex road conditions, a single high or low beam mode may not provide sufficient and appropriate illumination. Furthermore, traditional fog lights still have room for improvement in terms of heat dissipation, aesthetic integration, and coordination with the overall vehicle design. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a novel fog light lens that can achieve better light pattern combinations and more flexible lighting mode switching through more precise optical design and multi-channel control, thereby significantly improving the overall lighting effect and driving safety under different weather and road conditions while ensuring good penetration.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A novel fog light lens, comprising: Two reflectors; Two light-changing mechanisms are respectively set corresponding to the two reflectors; The two lenses in the middle are used to switch between near and far beams; A direct beam is positioned above to supplement the low beam spot; The bottom center lens is used to supplement either low-light or high-light; And two oval lenses located on both sides to supplement the high beam spot.

[0006] Preferably, the two reflectors are of the right-hand reflector type, and each reflector corresponds to an independent light-changing mechanism.

[0007] Preferably, the two middle lenses can work separately or simultaneously to switch between high beam and low beam.

[0008] Preferably, a dual-path drive board is also included for controlling the working modes of the light-changing mechanism and each lens respectively.

[0009] Preferably, the light path of the upper direct beam head is a straight beam, which is used to supplement the light spot in the central area in low beam mode.

[0010] Preferably, the lower center lens has a switchable light pattern structure, which can provide low-beam or high-beam supplement as needed.

[0011] Preferably, the two elliptical lenses have an elliptical light-emitting structure, which is used to extend the lateral illumination range in high-beam mode.

[0012] Preferably, the system also includes a heat sink structure, which is manufactured using a die-casting process and is used to dissipate heat from the lens system.

[0013] Preferably, a glass decorative cover is also included, positioned in front of the lens, and has a transparent or semi-transparent structure.

[0014] Preferably, the fog light lens supports at least one of the following operating modes: pure white light mode; pure yellow light mode; simultaneous yellow and white light mode; and combined high beam and low beam lighting mode.

[0015] The beneficial effects of this utility model are as follows: By integrating two independent reflectors and a light-changing mechanism, a central main switching lens, and multiple dedicated supplementary lenses (a direct low-beam head, a switchable mid-lower lens, and an elliptical high-beam lens), this invention can achieve pure white light, pure yellow light, a mixture of yellow and white light, and various high / low beam combination modes. Users can flexibly select the optimal lighting scheme based on real-time weather (such as fog, rain, and snow) and road conditions (such as urban areas, highways, and curves), achieving an upgrade from a single function to scene-adaptive operation. Through the collaborative work of multiple optical channels, highly optimized light patterns can be generated. Specifically, the upper direct head effectively supplements the central area illuminance in low-beam mode, improving low-beam uniformity; the elliptical lenses on both sides significantly expand the lateral illumination range in high-beam mode, improving visibility on both sides of the road; and the lower central lens, as a variable supplementary unit, further enhances the flexibility of light pattern adjustment. Ultimately, the low beam pattern was wide and uniform (e.g., from 40° left to 40° right, and from 0° up to 13.5° down), while the high beam pattern showed better performance in both width and height (e.g., from 40° left to 40° right, and from 4° up to 13.5° down), and the illuminance index was excellent.

[0016] Despite its complex optical functions, the integrated design of multiple lenses, reflectors, and drive control unit (dual-path drive board) results in a compact lens system that is easy to arrange within limited fog light installation space, thus optimizing the overall vehicle styling. The die-cast radiator efficiently dissipates heat generated by LEDs and other light sources, ensuring stable temperatures for optical components during prolonged operation and preventing light decay or component damage due to overheating, thereby improving the lifespan and reliability of the entire fog light system. The front glass decorative cover not only protects and seals the internal precision optical components, but its transparent or semi-transparent properties also allow it to better integrate with the front design of the car, enhancing the overall aesthetic appeal.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0019] Example refer to Figures 1 to 4 As shown, this embodiment provides a novel fog light lens.

[0020] Core Optical System Components: Reflector Assembly: The system comprises two independent right reflectors 101 for collecting and initially directing light emitted from a light source (such as an LED chip). Each reflector 101 has a specific curved surface design on its inner wall to optimize light reflection efficiency and emission angle. Beam Modulation Mechanism: Corresponding to the two reflectors 101, two independent beam modulation mechanisms 102 are provided. Each beam modulation mechanism 102 preferably employs an electromagnetically driven or stepper motor-driven light-blocking plate (such as a baffle or lens holder) structure. By controlling the movement position of the light-blocking plate (such as raising or lowering), the blocking state of the corresponding light path can be changed, thereby achieving the switching of the light pattern of that channel (e.g., switching from a near-beam cutoff line light pattern to a high-beam unblocked light pattern). Main Switching Lens Assembly: Located in the middle of the optical system, this assembly comprises two optical lenses 103. These two lenses 103 work in conjunction with the two beam modulation mechanisms 102 and are the main components for generating the standard near-beam and high-beam core light patterns. By controlling the state of the two light-changing mechanisms 102 (such as working simultaneously or working individually), the main lens group can output different combinations of light patterns.

[0021] Auxiliary supplementary lens group: Direct supplementary head: Located above the system, it is a collimating lens 104 with a fixed focal length. Its optical axis is substantially parallel to the vehicle's direction of travel. In low beam mode, it is illuminated to project a concentrated spot of light onto a distant area directly in front of the vehicle to compensate for any insufficient illumination in that area by the main low beam pattern. Lower switchable lens: Located in the middle of the lower part of the system, it can integrate a miniature beam-changing mechanism in front of it or employ a bifocal design 105. Through drive control, this lens 105 can switch between "low beam supplement" mode (providing a wider near-field paving light) and "high beam supplement" mode (providing a more concentrated forward searchlight). Elliptical high beam lenses: Located on both sides of the system, one on each side 106. The optical surfaces of these lenses 106 are designed with different curvatures in the vertical and horizontal directions, thus forming an elliptical light spot. They are primarily activated in high beam mode to project wide illumination onto areas on both sides of the road, significantly increasing the lateral coverage of the high beam.

[0022] Control and Drive System: The system is equipped with a dual-channel drive board 201. This drive board 201 integrates power management circuitry and a logic control unit. One output is used to independently or jointly drive the electromagnets or motors of the two main dimming mechanisms 102. The other output is used to independently control the switching and dimming (e.g., to achieve pure yellow light, pure white light, or a mixture of yellow and white light) of the light sources (LEDs) corresponding to each auxiliary supplementary lens 104, 105, and 106. The drive board 201 receives signals from the vehicle lighting control switch or the intelligent body control module (BCM) and automatically configures the status of each dimming mechanism and the on / off state and brightness of each light source according to preset or selected modes (such as "city low beam," "high beam," "severe weather yellow light mode," etc.).

[0023] Heat dissipation and mechanical structure: The entire optical module (reflector, lens, etc.) is mounted on a heat sink 301 base made of aluminum alloy using a die-casting process. The back of the heat sink 301 is designed with dense heat dissipation fins to increase the contact area with the air. The light source (LED module) is directly mounted in a designated position on the heat sink 301 base, ensuring that the heat it generates is efficiently conducted to the heat sink body through thermally conductive materials (such as thermal grease) and dissipated into the environment through the fins, guaranteeing stable long-term system operation.

[0024] Appearance and Protection: At the very front of the lens system, a glass decorative cover 401 is installed. This cover is made of high-transmittance polycarbonate (PC) or glass, and its surface can be treated with anti-reflective, anti-fog, and abrasion-resistant coatings. The glass decorative cover 401 is sealed to the lamp housing, serving to prevent dust and water damage (typically meeting IP67 or higher standards) and protect the internal precision optical components from physical damage. Its design can seamlessly integrate with the lines of the car's front bumper, enhancing its aesthetics.

[0025] Example of working modes: Pure white light low beam mode: The two main beam-changing mechanisms 102 are in the low beam position, forming a clear low beam cutoff line; the upper direct beam supplement head 104 is lit; the middle and lower switchable lenses 105 are in "low beam supplement" mode and lit; the elliptical lenses on both sides 106 are not working; all light sources are white light. This mode provides wide and uniform near-field illumination, suitable for urban night roads. Pure yellow light fog mode: The light pattern configuration is similar to the "pure white light low beam mode", but all light sources are driven by yellow light (or amber LEDs are used). Taking advantage of the strong penetrating power of yellow light, it is suitable for foggy, rainy, and snowy weather. Yellow and white light mixed enhancement mode: The main light pattern is low beam, but white light and yellow light sources are lit simultaneously in a certain proportion, improving the overall brightness while ensuring a certain degree of penetrability. Full-function high beam mode: Both main beam-switching mechanisms 102 switch to the high beam position, and the cutoff line is removed; the upper direct beam head 104, the middle and lower switchable lens 105 (set to "high beam supplement" mode), and the two elliptical lenses 106 are all illuminated. This mode provides powerful illumination with a long illumination distance and a wide lateral range, suitable for use in the countryside or on highways where there are no oncoming vehicles.
