Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting, and in particular to a reversing light outer lens and the reversing light thereof. Background Technology

[0002] As a core component of a vehicle's active safety lighting system, reversing lights play a dual crucial role in reversing scenarios: Firstly, they provide clear illumination of the area behind the vehicle, eliminating blind spots, especially in low-visibility conditions such as nighttime, rain, or fog. They must accurately illuminate the road, obstacles, and surrounding environment behind the vehicle to help the driver judge distances and avoid risks. Secondly, their specific light signals convey warning information that the vehicle is reversing to vehicles, pedestrians, and non-motorized vehicles behind, reminding surrounding road users to avoid collisions in time. Due to their importance, the light distribution of reversing lights must strictly adhere to relevant regulations and standards, as shown in the attached... Figure 1 The image shows the light intensity distribution diagram of the reversing light in GB5920-2024, which is a standard in the existing technology. This standard clearly defines the core parameters of the reversing light, such as the light intensity range, illumination angle, and light spot shape. It requires that the light intensity in key areas must reach a preset threshold to ensure the effectiveness of lighting, while avoiding excessive glare that may affect others. In the international market, it is necessary to meet the relevant ECE regulations to ensure the product's compliance worldwide.

[0003] However, existing reversing lights have significant limitations in their structural design, generally employing a single installation direction adaptation design. This means a single reversing light can only meet the needs of either horizontal or vertical installation. The core problem with this design is that the light distribution characteristics are strongly tied to the installation direction. Key structural elements such as the lens refraction surface and light source layout are optimized based on a preset installation direction. If the actual installation direction deviates from the design direction, it directly leads to deviations in light distribution from standard requirements. For example, if a reversing light designed for horizontal installation is changed to vertical installation, its main light band, originally intended to cover the horizontal area behind the vehicle, will shift to the vertical direction. This results in insufficient light intensity in the core lighting areas behind the vehicle (such as directly behind the rear and the nearby areas on both sides), while non-critical areas experience ineffective illumination, making it difficult for the driver to clearly identify the position and outline of obstacles behind. Conversely, a vertically designed reversing light, when installed horizontally, may produce glare or insufficient illumination angle, failing to meet the standard requirements for horizontal light coverage. This inaccurate light distribution not only significantly weakens the reversing lighting effect but also reduces the visibility of warning signals, seriously threatening the safety of the reversing process.

[0004] Furthermore, the single installation method results in extremely poor versatility for reversing lights, causing numerous inconveniences in vehicle production, modification, and maintenance. In vehicle manufacturing, different vehicle models (such as sedans, SUVs, trucks, and special-purpose vehicles) have significantly different rear structures, requiring different reversing light installation directions: sedans mostly use horizontal installation, while some commercial vehicles or special-purpose vehicles require vertical installation to fit the body structure. To meet the needs of different models, automakers need to develop and produce two types of reversing lights, one for horizontal and one for vertical installation. This not only increases product development cycles and mold investment costs but also leads to an increase in the variety of parts inventory and higher warehousing management costs. In the automotive modification market, with the growth in demand for personalized modifications, some car owners upgrade or adjust their vehicle's rear lighting system. However, the single installation direction of reversing lights limits modification flexibility. Car owners need to spend a lot of time selecting products compatible with the original vehicle's installation direction. If the wrong selection is made, either the lights cannot be installed, or the installed lights may face penalties from traffic management departments due to non-compliant light distribution. In repair and replacement scenarios, repair shops need to stock reversing lights with various installation directions to meet the repair needs of different car models, which increases the shop's operating costs. If car owners purchase and replace them themselves, they are also prone to making the wrong purchase due to a lack of understanding of the installation direction, which affects repair efficiency and generates additional time and economic costs.

[0005] As the automotive industry moves towards diversification and customization, the market share of special-purpose vehicles and modified vehicles is gradually increasing, placing higher demands on the installation flexibility and versatility of reversing lights. Existing reversing lights with only one installation direction can no longer meet the actual needs of the entire industry chain. Their problems, such as light distribution compliance depending on the installation direction, poor versatility, and high costs, have become key bottlenecks restricting the adaptability and safety improvement of vehicle lighting systems. Therefore, developing a reversing light that is compatible with both horizontal and vertical installation methods and meets the relevant standard light distribution requirements has significant practical significance and market value.

[0009] Another advantage of this utility model is that it provides a reversing light outer lens and a reversing light, which provides more comprehensive lighting coverage.

[0032] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0033] Those skilled in the art should understand that, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0034] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0035] Reference Appendix Figure 2 To be continued Figure 6 As shown, the reversing light outer lens 11 of this utility model is schematically illustrated. (See attached diagram.) Figure 2 and 3As shown, the reversing light outer lens 11 includes a base plate 112 and a plurality of tower-shaped lens units 111. The tower-shaped lens units 111 are uniformly mounted in a rectangular array on the base plate 112. Each tower-shaped lens unit 111 has a light band refraction area 81 and a light spot refraction area 82. The light spot refraction area 82 is arranged around the edge of the tower-shaped lens unit 111. The light band refraction area 81 extends upward from the light spot refraction area 82 and converges to a point, so that light rays perpendicular to the direction of the base plate 112 are refracted by the light band refraction area 81 and emitted from the base plate 112, presenting a light band of 0° to 40°. Light rays refracted by the light spot refraction area 82 and emitted from the base plate 112 present a light spot of 40° to 50°. This allows the reversing light outer lens 11 to emit a light spot that meets national standards whether it is installed vertically or horizontally.

[0036] In particular, such as Figure 3 The diagram shown is a partially enlarged schematic of the reversing light outer lens 11. The light spot refraction area 82 includes a pair of horizontal light spot refraction areas 821 and a pair of vertical light spot refraction areas 822, which are spaced apart and arranged around the bottom edge of the tower-shaped lens unit 111. Specifically, the bottom of the tower-shaped lens unit 111 is square, and the tower-shaped lens units 111 are mounted in a rectangular array on the base plate 112. The direction along the long side of the base plate 112 is defined as the horizontal direction, and the direction along the short side of the base plate 112 is defined as the vertical direction. The horizontal light spot refraction area 821 is symmetrically arranged on both sides of the bottom edge of the tower-shaped lens unit 111, and is aligned with the vertical axis, extending upwards to form a curved surface. The vertical light spot refraction area 822 is symmetrically arranged on the other two sides of the bottom edge of the tower-shaped lens unit 111, and is aligned with the horizontal axis, extending upwards to form a curved surface. In other words, the horizontal light spot refraction area 821 and the vertical light spot refraction area 822 together form the four bottom edges of the tower-shaped lens unit 111.

[0037] It is worth mentioning that the light band refraction area 81 includes a pair of horizontal light band refraction areas 811 and a pair of vertical light band refraction areas 812. The horizontal light band refraction area 811 corresponds to the horizontal light spot refraction area 821, and the vertical light band refraction area 812 corresponds to the vertical light spot refraction area 822. That is, the horizontal light band refraction area 811 is located above the horizontal light spot refraction area 821, and the vertical light band refraction area 812 is located above the vertical light spot refraction area 822. The horizontal light band refraction area 811 and the vertical light band refraction area 812 converge at an intersection point 90 from the upward converging curved surface extensions of the horizontal light spot refraction area 821 and the vertical light spot refraction area 822. The projection of the intersection point 90 is located at the geometric center of the tower-shaped lens unit 111. In other words, the horizontal light refraction zone 811 and the vertical light refraction zone 812 are roughly curved triangles that converge from above the tower-shaped lens unit 111 to form a square tower shape with the base square and the four sides converging upwards.

[0038] Specifically, a light beam perpendicular to the base plate 112 is refracted by the horizontal light strip refraction area 811 and emitted from the base plate 112 to form a horizontal light strip of 0° to 40°. A light beam of 40° to 50° is refracted by the horizontal light spot refraction area 821 and emitted from the base plate 112. Similarly, a light beam perpendicular to the base plate 112 is refracted by the vertical light strip refraction area 812 and emitted from the base plate 112 to form a vertical light strip of 0° to 40°. A light beam of 40° to 50° is refracted by the vertical light spot refraction area 822 and emitted from the base plate 112. This allows the reversing light outer lens 11 to emit a light spot conforming to national standards whether installed vertically or horizontally. The reversing light outer lens 11 is compatible with both horizontal and vertical installation methods, eliminating the need to change to different models depending on the vehicle model or installation scenario, thus adapting to the rear structure requirements of various vehicle types.

[0039] The base plate 112 and the tower-shaped lens unit 111 are integrally formed. This ensures the consistency of the overall structure, reduces mold, processing and assembly costs, avoids splicing errors, ensures the accurate relative positions of the curved surfaces of the tower-shaped lens unit 111, and ensures that the light distribution meets the design standards, effectively avoiding light effect deviation.

[0040] As attached Figures 7 to 9As shown, the reversing light 1 includes a circuit board 14, multiple light-emitting units 13, and multiple focusing lenses 12. The multiple light-emitting units 13 are arrayed and mounted on the circuit board 14. The multiple focusing lenses 12 are correspondingly mounted in front of the light-emitting units 13 to collimate the diffused light emitted by the light-emitting units 13 into parallel light L. The reversing light outer lens 11 is mounted in front of the focusing lens 12, so that the multiple tower-shaped lens units 111 face the focusing lens 12, and the plane of the base plate 112 is parallel to the plane of the circuit board 14. (See attached diagram) Figure 9 The diagram shows the optical path of the reversing light 1. Multiple focusing lenses 12 collimate the diffused light emitted by the light-emitting unit 13 into parallel light L. The parallel light L is refracted by the horizontal light strip refraction area 811 and emitted from the base plate 112, forming a horizontal light strip of 0° to 40°. It is also refracted by the horizontal light spot refraction area 821 and emitted from the base plate 112, forming a horizontal light spot of 40° to 50°. Similarly, the parallel light L is refracted by the vertical light strip refraction area 812 and emitted from the base plate 112, forming a vertical light strip of 0° to 40°. It is also refracted by the vertical light spot refraction area 822 and emitted from the base plate 112, forming a vertical light spot of 40° to 50°. This allows the reversing light 1 to emit a light spot conforming to national standards whether installed vertically or horizontally. The reversing light 1 is compatible with both horizontal and vertical installation methods, eliminating the need to change to different models depending on the vehicle type or installation scenario, thus adapting to the rear structure requirements of various vehicle types. (See attached diagram.) Figure 10 The diagram shown is a schematic representation of the optical simulation light spot of the reversing light 1. It can be understood that the reversing light 1 can emit a light spot conforming to national standards whether it is installed vertically or horizontally. Figure 11 This is a simulation verification data diagram of the light intensity when the reversing light 1 is installed horizontally. Figure 12 This is a simulation verification data diagram of the light intensity when the reversing light 1 is installed vertically.

[0041] The light-emitting unit 13 is an LED white light source. The use of white LEDs in the light-emitting unit 13 offers several core advantages: excellent color rendering, accurately reproducing the colors and details of objects behind the vehicle, significantly improving target visibility even at night or in low-visibility environments such as rain and fog, effectively reducing visual misjudgments by the driver when reversing; simultaneously, LED white light has a much higher luminous efficacy than traditional light sources, consumes less power for the same illumination brightness, generates less heat, and has strong operational stability, meeting the design requirements for energy conservation and emission reduction in vehicles; furthermore, LED light sources have extremely fast response speeds, instantly illuminating without delay after power-on, providing ample illumination and clear warnings immediately upon initiating reversing operations, helping to avoid collision risks more promptly than traditional light sources; in addition, its lifespan is up to tens of thousands of hours, with a failure rate far lower than traditional light sources, significantly reducing the frequency of reversing light replacements, lowering user maintenance costs and ease of use, further enhancing the product's practical value and market competitiveness.

[0042] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
