Description

Technical Field

[0001] This application relates to the field of automotive lighting technology, and in particular to an integrated high and low beam lens assembly and automotive lamp. Background Technology

[0002] The integrated design of high and low beam headlights is the current mainstream trend. Its core requirement is to achieve "compliant and anti-glare low beam, wide and bright high beam coverage" within a limited lamp cavity space, while ensuring that there is no obvious dark layering in the boundary area when switching between high and low beams (hereinafter referred to as "layering").

[0003] Existing high and low beam integrated lens modules generally suffer from the following technical defects: The core issue of high beam obstruction causing layering is as follows: To prevent high beams from directly hitting oncoming lanes, existing solutions typically place the "high beam LED light source + high beam reflector" below the beam pattern baffle (the beam pattern baffle is used to shape the low beam cutoff line and prevent low beam glare). However, because the high beam LED light source and high beam reflector are located below the beam pattern baffle, the high beam light, after being reflected by the reflector, will propagate towards the "upper edge area of ​​the low beam pattern" (i.e., the high and low beam boundary area). However, the beam pattern baffle itself has a certain thickness, and under its influence, the "lower edge" of the beam pattern baffle will block this propagation path, resulting in a "10°-15° light gap" in the high beam pattern at the boundary area. The low beam pattern complies with regulations (with a clear cutoff line), but the high beam pattern cannot completely coincide with the upper edge of the low beam cutoff line due to obstruction, ultimately resulting in a layering phenomenon of "a dark area above the low beam cutoff line and a discontinuity below the high beam coverage."

[0004] To solve this layering problem, the following methods are typically used for supplemental lighting: Option 1 (Adding an auxiliary light source): Adding an independent supplementary LED in the junction area can fill the gap, but it will increase the module size (the lamp cavity space is limited) and require an additional heat dissipation structure, thus increasing the cost by 15%-20%. Option 2 (adding a reflector): such as the "double reflector supplementary light structure" disclosed in patent CN209688732U, which uses a reflector to reflect the light from the distance and block the light, but the reflector angle needs to be precisely adjusted. Assembly errors can easily lead to light pattern deviation (error ±3° will cause failure), and multiple components increase the failure rate. Summary of the Invention

After being refracted by the deformable optical unit, it tilts towards the first beam to form a high beam pattern.

[0008] In some embodiments of the first aspect of this application, the edge of the beam pattern baffle facing the lens is arc-shaped, and a portion of the first beam emitted along this edge forms a cutoff line on the near beam pattern.

[0009] In some embodiments of the first aspect of this application, the second focal point is located on the edge of the light pattern baffle on the side facing the lens.

[0010] In some embodiments of the first aspect of this application, the lens body is a plano-convex lens, with the light-incident surface being a plane and the light-outceasing surface being a convex surface.

[0012] In some embodiments of the first aspect of this application, the concave surface on the light-incident surface of the lens body gradually bends towards the light-outceasing surface from the height of the optical axis along the height direction; as the height increases, the angle between the tangent direction of the concave surface and the light-incident surface of the lens body gradually increases.

[0013] In some embodiments of the first aspect of this application, the second reflecting surface is a first parabolic surface, the first parabolic surface includes a fourth focus, the fourth focus coincides with the first focus; the first parabolic surface is connected to the opening side of the ellipsoid away from the first focus and extends toward the second focus.

[0018] According to a second aspect of this application, a vehicle headlight is provided that employs an integrated high / low beam lens assembly as described in any embodiment of the first aspect.

[0019] Compared with the prior art, this application has the following advantages: 1. This application provides a deformable optical unit on the light-incident surface of the lens body, so that the light beam emitted by the high beam source is refracted by the deformable optical unit and tilted towards the first light beam emitted by the low beam source to form the low beam pattern, thereby forming the high beam pattern. The lower edge of the high beam pattern coincides with the cutoff line of the low beam pattern. Without the need for additional light source and reflector, the defect of layering phenomenon caused by the lower edge of the light pattern baffle blocking part of the light beam of the high beam source, resulting in "dark area above the low beam cutoff line and discontinuity below the high beam coverage", can be eliminated.

[0035] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] Example 1: This embodiment provides an integrated high and low beam lens assembly to prevent the layering phenomenon of "dark areas above the low beam cutoff line and discontinuities below the high beam coverage".

[0037] Please refer to Figure 1 and Figure 2 The integrated high and low beam lens assembly includes: a low beam light source 100, a high beam light source 200, a lens 300, a beam pattern baffle 400, a low beam reflector 110, and a high beam reflector 210.

[0038] Both the low beam light source 100 and the high beam light source 200 use LED light sources.

[0039] In order to control the low beam light source 100, this embodiment also includes a first PCB board 120, on which a circuit for controlling the low beam light source 100 to be turned on / off is provided.

[0040] Similarly, in order to control the high beam light source 200, this embodiment also includes a second PCB board 220, which is provided with a circuit for controlling the high beam light source 200 to turn on / off.

[0041] The first PCB board 120 and the second PCB board 220 are located at the bottom of the low beam light source 100 and the high beam light source 200, respectively. To secure them, mounting brackets 500 are provided at the bottom of the first PCB board 120 and the second PCB board 220, such as... Figure 2 As shown, the mounting bracket 500 is Z-shaped to accommodate the mounting positions of the first PCB board and the second PCB board 220.

[0042] The lens 300 includes a lens body 310 and a deformable optical unit 320 disposed on the light-incident surface of the lens body 310. It is worth mentioning that, as... Figure 2 As shown, the lens body 310 is a plano-convex lens, wherein the light-incident surface is flat and the light-excising surface is convex. The deformable optical unit 320 is located on the light-incident surface of the lens body 310 and shares the same light-excising surface with the lens body 310.

[0043] A beam pattern baffle 400 is positioned between the low beam reflector bowl 110 and the lens 300 to form a cutoff line for the low beam pattern.

[0044] According to low beam lighting regulations, the light pattern baffle 400 blocks upward / oncoming lane light (to avoid glare). Therefore, in this embodiment, the light pattern baffle 400 blocks the upper portion of the light beam at an angle greater than 15° to the horizontal before it enters the lens 300. Please refer to... Figure 2 and Figure 8 The edge of the light pattern baffle 400 facing the lens 300 is arc-shaped, and part of the light beam emitted along this edge forms a cutoff line on the near-beam light pattern.

[0045] The low-beam reflector 110 is used to reflect the light beam emitted by the low-beam source 100. For details, please refer to... Figure 2 The near-beam reflector 110 is mainly divided into two parts, including a first reflective surface 111 and a second reflective surface 112.

[0046] It is worth mentioning that the low-beam reflector 110 is made of a material with good heat resistance, such as glass or synthetic polymers such as polycarbonate PC, polyetherimide PEI, etc.

[0047] like Figure 4As shown, the first beam emitted by the near light source 100 is reflected by the first reflecting surface 111, partially intercepted by the light pattern baffle 400, and then reaches the lens body 310. After being refracted by the lens body 310, it forms a near light pattern with a cutoff line.

[0048] like Figure 5 As shown, the second beam emitted by the near-light source 100 is reflected by the second reflecting surface 112 and reaches the deformable optical unit 320. After being refracted by the deformable optical unit 320, it forms supplementary light above the cutoff line of the near-light pattern. It is worth mentioning that "refracted by the deformable optical unit 320" means that the beam enters from a part of the deformable optical unit 320 and exits through the light-emitting surface shared by the deformable optical unit 320 and the lens body 310.

[0049] It should be noted that the low beam pattern of the headlight is divided into Zone I, Zone II, Zone III, and Zone IV. The "upper side" mentioned here refers to Zone III.

[0050] In this embodiment, redundant light (i.e. light beam not reflected by the first reflective surface 111) emitted by the near-light source 100 is reflected by the second reflective surface 112 to the deformable optical unit 320, and the propagation path of the light beam is changed by the deformable optical unit 320. Finally, without the need for additional light source and reflector, supplementary light can be formed above the cutoff line of the near-light pattern to eliminate the dark area.

[0051] To achieve the above effects, the present application has made the following design to the first reflecting surface 111, the second reflecting surface 112, and the deformable optical unit 320.

[0052] Please refer to Figure 2 and Figure 4 The first reflecting surface 111 is an ellipsoid, which includes a first focal point k1 and a second focal point k2. The near light source 100 is disposed at the first focal point k1. Therefore, the first light beam emitted from the near light source 100 is reflected by the first reflecting surface 111 and converges at the second focal point k2, and then reaches the light incident surface of the lens body 310 through the second focal point k2.

[0053] Meanwhile, in order to form the cutoff line of the near beam pattern, the second focal point k2 is located exactly on the edge of the beam pattern baffle 400 facing the lens.

[0054] like Figure 2 and Figure 5 As shown, the second reflecting surface 112 is a first parabolic surface, which includes a fourth focus k4 that coincides with the first focus k1. The first parabolic surface is connected to the opening side of the ellipsoid away from the first focus k1 and extends towards the second focus k2.

[0055] The parabolic surface has a single focal point (such as the fourth focal point k4 in this embodiment), at which light emitted by a light source placed in the focal point is projected a great distance after being reflected by the surface. Being projected a great distance means that these rays do not converge toward an area located at least 10 times the size of the reflector. In other words, the reflected light does not converge toward a converging region; or, if the reflected light does converge, the converging region is located at a distance greater than or equal to 10 times the size of the reflector.

[0056] like Figure 2 , Figure 3 and Figure 6 As shown, the deformable optical unit 320 includes a concave surface 321 disposed on the light-incident surface of the lens body 310, a prism, or a group of microlenses. The concave surface, prism, or microlens group has a third supplementary light focus k3, which is located between the first focus k1 and the second focus k2. This embodiment forms the deformable optical unit 320 by changing part of the shape of the light-incident surface of the lens body 310, thereby changing the local beam propagation path.

[0057] Taking the concave surface 321 as an example, such as Figure 3 As shown, the concave surface 321, starting from the height of the optical axis L1 on the light-incident surface of the lens body 310, gradually curves towards the light-outceasing surface along the height direction; and, as the height increases, the angle β between the tangent direction of the concave surface 321 and the light-incident surface of the lens body gradually increases. With this shape of the concave surface 321, a third supplementary light focus k3 is formed in this area between the first focus k1 and the second focus k2.

[0058] Finally, redundant light emitted from the near-light source 100 is reflected by the second reflective surface 112 to the deformable optical unit 320, forming supplementary light on the cutoff line of the near-light pattern and eliminating the sense of layering.

[0059] Please refer to Figure 2 and Figure 8 The high beam reflector 210 is disposed on the lower side of the light pattern baffle 400. The light beam emitted by the high beam light source 200 is reflected by the high beam reflector 210 to the deformable optical unit 320. After being refracted by the deformable optical unit 320, it tilts towards the first light beam to form a high beam pattern. The lower edge of the high beam pattern coincides with the cutoff line of the low beam pattern.

[0060] In this embodiment, the deformable optical unit 320 further changes the propagation path of the beam emitted by the high beam source 200 reflected by the high beam reflector bowl 210, causing the beam to tilt toward the first beam (i.e., the near beam pattern), so that the high beam pattern as a whole shifts toward the near beam pattern, thereby eliminating the discontinuity formed by the partial obstruction of the beam of the high beam source 200 by the beam pattern baffle 400.

[0061] It is worth mentioning that the high beam reflector bowl 210 is made of a material with good heat resistance, such as glass or synthetic polymers such as polycarbonate PC, polyetherimide PEI, etc.

[0062] Specifically, the high beam reflector 210 includes a third reflective surface 211, which is a second parabolic surface. This second parabolic surface includes a fifth focal point k5, and the high beam source 210 is positioned at the fifth focal point k5. For example... Figure 6 As shown, the light beam emitted by the far-light source 210 is collimated into the deformable optical unit after being reflected by the second parabolic surface.

[0063] In order to control the width of the high beam pattern, such as Figure 9 and Figure 10 As shown, the high beam reflector bowl 210 has a fourth reflector surface 212 on each side of the third reflector surface 211 along the horizontal direction; the fourth reflector surface 212 reflects the light beam emitted by the high beam source 200 in the horizontal direction to form a convergence, thereby achieving the purpose of controlling the width of the high beam pattern.

[0064] On the other hand, in the horizontal direction, the high beam reflector bowl 210 is provided with a light-blocking part 213 on the outer side of the fourth reflective surface 212. The light-blocking part 213 is partially made of opaque material to block the beam emitted by the low beam source 100 and other stray light, so as to prevent these stray lights from leaking out from both sides and affecting the high beam pattern.

[0065] In this embodiment, the back side of the high beam reflector 210 is provided with a fifth reflective surface 214 facing the low beam light source 100. For example... Figure 7 As shown, the third beam emitted by the near-beam light source 100 is reflected by the fifth reflecting surface 214 to the first reflecting surface 111, and then reflected by the first reflecting surface 111 to the deformable optical unit 320. After being refracted by the deformable optical unit 320, a zone III light pattern is formed above the cutoff line of the near-beam light pattern, which is used to illuminate road signs, signs, traffic signs, etc. In this embodiment, the redundant light of the near-beam light source 100 is utilized again through the joint cooperation of the fifth reflecting surface 214, the first reflecting surface 111, and the deformable optical unit 320, so that a zone III light pattern can be formed without adding a new light source and a reflector.

[0066] Example 2: This second embodiment provides a vehicle headlight that uses the integrated high and low beam lens assembly as described in the first embodiment.
