Technical Field
[0001] This utility model relates to the field of automotive lighting technology, and in particular to a novel auxiliary low beam module. Background Technology
[0002] With continuous innovation in automotive lighting technology and consumers' increasing focus on the design of lighting fixtures, in order to achieve a more stylish look...
[0003] In terms of both design and functionality, headlights are gradually moving towards miniaturization, automation, and multi-functionality. This trend has become particularly popular in recent years.
[0004] The ultra-narrow lens module makes the headlights more aesthetically pleasing and technologically advanced.
[0005] When providing low beam functionality, existing ultra-narrow lens modules can only extend the low beam downwards by 7 degrees due to the use of ultra-narrow lenses. The low beam can only extend downwards to 7 meters in front of the vehicle, resulting in a dark area, or blind spot, visible in front of the vehicle from the driver's seat. The existence of the blind spot directly reduces the safety of driving at night.
[0006] Therefore, there is an urgent need to develop a new type of auxiliary low beam module to supplement the low beam function provided by the ultra-narrow lens module, thereby solving the above problems and further improving driving safety. Utility Model Content
[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing a novel auxiliary low beam module that effectively solves the problems existing in the prior art.
[0008] This utility model is achieved through the following technical solution:
[0009] A novel auxiliary low beam module includes a lens, a light source, and a condenser. The condenser is disposed between the lens and the light source. Light emitted from the light source is collected and collimated by the condenser to form an auxiliary low beam with a cutoff line. The auxiliary low beam passes through the lens to form an auxiliary low beam pattern, which is used to extend the downward illumination range of the main low beam pattern and eliminate dark areas. The condenser includes a main body with a focusing structure above it. A forward-extending light shield is integrally disposed below the focusing structure on the main body. A reflective layer is disposed on the outer surface of the light shield, and a cutoff line structure is disposed on the upper surface of the light shield. An angled end face is disposed at the front end of the light shield, which is used to adjust the angle of the total internal reflection light on the lens and reflect it out, so that it may or may not enter the III zone of the main low beam pattern.
[0010] Furthermore, according to the novel auxiliary low beam module of this utility model, the angle α of the end face is 5 to 80 degrees. By setting the angle α, the light reflected from the end face is deflected downward and cannot enter the III zone of the main low beam pattern.
[0011] Furthermore, according to the novel auxiliary low beam module of this utility model, a transition platform of 0.2 to 1 mm is provided on the upper edge of the end face.
[0012] Furthermore, according to the novel auxiliary low beam module of this utility model, the angle α of the end face is 90 to 105 degrees. By setting the angle α, the light reflected from the end face is shifted forward or upward and enters the III zone of the main low beam pattern to supplement the light in the III zone.
[0013] Furthermore, according to the novel auxiliary low beam module of this utility model, the light-concentrating structure includes multiple light-concentrating elements, each light-concentrating element including a light-emitting part and a collimating part; the light source includes multiple LED light sources, each LED light source corresponding to one collimating part, and the light emitted by the LED light source is collected and collimated by the collimating part before being emitted by the light-emitting part.
[0014] Furthermore, according to the novel auxiliary low beam module of this utility model, the focusing structure includes three focusing bodies, the focusing body located in the middle is used to provide the downward illumination range of the auxiliary low beam pattern, and the focusing bodies located on both sides are used to provide the left and right illumination range of the auxiliary low beam pattern.
[0015] Furthermore, according to the novel auxiliary low beam module of this utility model, the longitudinal cross-sectional line of the light-emitting part of the light-concentrating body located in the middle is a convex arc line with an angle set at the top and bottom, and the longitudinal angle adjustment and focusing of the light is realized by the cooperation of the angle and the convex arc line; the transverse cross-sectional line of the light-emitting part of the light-concentrating body located on both sides is a concave arc line with an angle set at the outside and the inside, and the transverse angle adjustment and diffusion of the light is realized by the cooperation of the angle and the concave arc line.
[0016] Furthermore, according to the novel auxiliary low beam module of this utility model, each of the light-emitting parts of the light-concentrating element is provided with longitudinal stripes.
[0017] Furthermore, according to the novel auxiliary low beam module of this utility model, the light-emitting surface of the lens facing outward is provided with a grid pattern.
[0018] Furthermore, according to the novel auxiliary low beam module of this utility model, the light-incident surface of the lens facing the light source is an outwardly convex spherical surface.
[0019] This utility model features a simple structure and convenient installation. Firstly, the provided low-beam auxiliary beam supplements the main low-beam beam, illuminating a range of 2-30 meters in front of the vehicle. This increases the downward illumination range of the main low-beam beam to 18 degrees, eliminating any dark areas visible from the driver's seat and improving overall light coverage, thus enhancing nighttime driving safety and effectively addressing existing technical problems. Secondly, the end face of the condenser can be configured according to the characteristics of Zone III in different main low-beam beams, ensuring the auxiliary low-beam beam meets the needs of Zone III in various main low-beam beams. When Zone III of the main low-beam beam does not require supplemental light, the tilt angle of the end face is 5-80 degrees; when Zone III requires supplemental light, the tilt angle is 90-105 degrees. Secondly, the light-emitting surface of the lens is decorated with a grid pattern. The grid pattern softens the sharpness of the cutoff line between light and dark on the auxiliary beam pattern, so that there is no obvious abrupt change at the point where it meets the main beam pattern, resulting in a clear junction line on the ground.

Detailed Implementation
[0030] 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.
[0031] like Figure 1-8As shown, a novel auxiliary low beam module includes a lens 1, a light source 2, a condenser 3, a lens bracket 4, and a heat sink 10. The lens 1 is located at the front end of the lens bracket 4. From the inside to the outside, the condenser 3, the light source 2, and the heat sink 10 are arranged sequentially at the rear end of the lens bracket 4 and fixed to the lens bracket 4 by the heat sink 10. The heat sink 10 is used to dissipate heat from the light source 2. Thermal grease can also be applied between the two to improve the heat dissipation effect and thus extend the service life of the light source 2. Of course, heat dissipation fins can also be provided on the heat sink 10 to increase the heat dissipation area and further improve the heat dissipation effect. The light emitted by the light source 2 is collected and collimated by the condenser 3 to form a near beam with a cutoff line. The near beam is then passed through the lens 1 to form a near beam pattern. The near beam pattern is used to expand the downward illumination range of the main near beam pattern and eliminate dark areas. The condenser 3 includes a main body 31, a light-gathering structure 311 is provided above the main body 31, and a forward-extending light shield 312 is integrally provided below the light-gathering structure 311. A reflective layer is provided on the outer surface of the light shield 312, and a cutoff line structure 3122 is provided on the upper surface of the light shield 312. An angled end face 3121 is provided at the front end of the light shield 312. The end face 3121 is used to adjust the angle of the total internal reflection light on the lens 1 and reflect it out, so that it may or may not enter the III zone of the main near beam pattern. Specifically, the light source 2 and the condenser 3 are both fixed to the lens bracket 4 by the heat sink 10, making installation convenient and quick. A single installation can simultaneously fix the light source 2, the condenser 3, and the heat sink 10 to the lens bracket 4, greatly improving production efficiency. In this embodiment, mounting platforms 41 are symmetrically arranged on both sides of the rear end of the lens bracket 4. Each mounting platform 41 has two mounting post holes 5, and a limiting post 6 is provided between the two mounting post holes 5. The condenser 3 also includes mounting feet 32, which are symmetrically arranged on both sides of the main body 31. Each mounting foot 32 has a limiting groove 7 and a mounting hole 8. The light source 2 includes an LED light source 21 and a PCB board 22. The LED light source 21 is mounted on the PCB board 22, which also has limiting holes 9 and mounting holes 8. The heat sink 10 also has limiting holes 9 and mounting holes 8. The limiting post 6 passes through the limiting groove 7 on the condenser 3, the limiting hole 9 on the PCB board 22, and the limiting hole 9 on the heat sink 10 in sequence, so that the light source 2, the condenser 3, and the heat sink 10 are simultaneously limited on the lens bracket 4. Then, screws are used to pass through the mounting holes 8 on the heat sink 10, the light source 2, and the condenser 3 in sequence and connect to the mounting post hole 5, thereby fixing the light source 2, the condenser 3, and the heat sink 10 on the lens bracket 4 at the same time. The installation is convenient and quick.The light emitted by the LED light source 21 is collected and collimated by the focusing structure 311. After being blocked by the light shield 312, the emitted light forms a low beam auxiliary beam with a cutoff line between light and dark. The low beam auxiliary beam forms a low beam auxiliary light pattern through the lens 1. The low beam auxiliary light pattern is used to extend the downward illumination range of the main low beam pattern. By supplementing the main low beam pattern with the light of the low beam auxiliary light pattern, the area in front of the vehicle is illuminated within 2-30 meters, so that the downward illumination range of the main low beam pattern reaches 18 degrees. This avoids the dark area that can be seen in front of the vehicle from the driver's position, thus eliminating the dark area, supplementing the light coverage in front of the vehicle, and further improving the safety of night driving. This can effectively solve the problems existing in the prior art.
[0032] Furthermore, the focusing structure 311 includes multiple focusing elements 30, each focusing element 30 including a light-emitting section 301 and a collimating section 302; the light source 2 includes multiple LED light sources 21, each LED light source 21 corresponding to one collimating section 302. The light emitted by the LED light sources 21 is collected and collimated by the collimating section 302 and then emitted through the light-emitting section 301. Specifically, the focusing structure 311 includes three focusing elements 30. The focusing element 30 in the middle is used to provide downward illumination of the near beam auxiliary light pattern, and the focusing elements 30 on both sides are used to provide left and right illumination of the near beam auxiliary light pattern. To improve the downward illumination range and distance of the low beam assist light pattern, the longitudinal cross-section of the light-emitting part 301 on the central focusing element 30 is a convex arc line with an angled arrangement, lower at the top and higher at the bottom. Through the combination of the angle and the convex arc line, the longitudinal angle adjustment and focusing of the light are achieved. Angle adjustment expands the downward illumination range of the low beam assist light pattern, and focusing concentrates the light near the light cutoff line, improving the illumination distance of the low beam assist light pattern. This ensures that the low beam assist light pattern can illuminate an area of 2-30 meters in front of the vehicle, further improving nighttime driving safety. In this embodiment, the focusing structure 311 includes three focusing elements 30 arranged in a straight line. The central focusing element 30 provides the downward illumination range of the low beam assist light pattern, while the two side focusing elements 30 provide the left and right illumination ranges of the low beam assist light pattern. To ensure the illumination range and uniformity of the low beam assist beam on both sides, the transverse cross-section of the light-emitting portion 301 of the light-concentrating bodies 30 on both sides is a concave arc line with an angled shape, lower on the outside and higher on the inside. The combination of the angle and the concave arc line allows for lateral adjustment and diffusion of the light. Angle adjustment expands the illumination range of the low beam assist beam to the left or right, while diffusion improves the uniformity of the low beam assist beam. To expand the downward illumination range and increase the illumination distance of the low beam assist beam, the longitudinal cross-section of the light-emitting portion 301 on the three light-concentrating bodies 30 is a convex arc line with an angled shape, lower on the top and higher on the bottom. The combination of the angle and the convex arc line allows for a wider and longer downward illumination range of the light emitted from the light-emitting portion 301, reaching up to 18 degrees, further improving light coverage and ensuring that the low beam assist beam can illuminate an area of 2-30 meters in front of the vehicle, thus further improving nighttime driving safety.
[0033] To improve the quality of the low beam assist beam, longitudinal stripes 3011 are provided on the light-emitting portion 301 of each light-concentrating element 30. The longitudinal stripes 3011 are used to diffuse a soft and uniform low beam assist beam, further improving the quality of the low beam assist beam. At the same time, it can also avoid the problem of low precision caused by the large area processing of the light-emitting portion 301.
[0034] To prevent the lens holder 4 from needing a light-blocking plate to avoid sunlight focusing and burning it, which would increase production costs and hinder lightweight development, the light-incident surface 11 of the lens 1 facing the light source 2 is an outwardly convex spherical surface. The spherical light-incident surface 11 disperses the incoming sunlight, preventing it from focusing and thus eliminating the need for a light-blocking plate on the lens holder 4. This further reduces production costs and the weight of the module, facilitating lightweight development.
[0035] In order to soften the sharpness of the cutoff line between light and dark on the auxiliary beam pattern and prevent abrupt changes at the point where it merges with the main beam pattern, resulting in a noticeable junction line on the ground, a grid pattern 121 is provided on the outward-facing light-emitting surface 12 of lens 1.
[0036] Example 1
[0037] Depend on Figure 4 It is known that when the III zone of the main near beam pattern does not require supplementary light, the angle α of the end face 3121 is 5–80 degrees. By setting the angle α, the light reflected from the end face 3121 is deflected downwards and cannot enter the III zone of the main near beam pattern, thus ensuring that no light enters the III zone of the main near beam pattern when the near beam auxiliary beam pattern is working. Specifically, in order to prevent the upper edge of the end face 3121 from being too sharp and reducing the life of the concentrator 3 mold, a transition platform 31211 with a width of 0.2–1 mm is provided at the upper edge of the end face 3121. In this embodiment, the angle α of the end face 3121 is 70 degrees and the width of the transition platform 31211 is 0.7 mm, which achieves the best effect.
[0038] Example 2
[0039] Depend on Figure 8 Unlike Embodiment 1, when supplementary light is needed in Zone III of the main near beam pattern, the angle α of the end face 3121 is 90–105 degrees. By setting the angle α, the light reflected from the end face 3121 is shifted forward or upward and enters Zone III of the main near beam pattern, thereby ensuring that the near beam auxiliary beam pattern can supplement the light in Zone III of the main near beam pattern when it is working. In this embodiment, the angle α of the end face 3121 is 100 degrees, which yields the best results.
[0040] To meet the requirements of different main and low beam patterns for Zone III, we only need to develop two concentrators 3 with different end face 3121 setting angles. By selecting the appropriate concentrator 3 for module installation as needed, the requirements can be met. This avoids the need to develop two different auxiliary low beam modules to meet the requirements of different main and low beam patterns for Zone III, further reducing production costs and R&D cycle.
