Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle lighting technology, and more particularly to a light-emitting system, vehicle lamp, and vehicle. Background Technology
[0002] With the advent of LEDs and the development of the automotive lighting field, designing a car headlight is no longer a problem. Effectively combining the cost, personalization, efficiency, and performance of headlight modules has become the goal pursued by people.
[0003] Since its invention, the integrated high and low beam module has evolved into various design forms, with the condenser + baffle + lens configuration being the most widely used. This design typically uses a condenser as the primary optical element to focus the energy of the LEDs and distribute it onto the baffle. A focusing lens then images the shape of the baffle, with the high and low beams positioned on the upper and lower sides of the baffle respectively, thus forming the integrated high and low beam module. However, in high beam mode, when both high and low beams are turned on simultaneously, there is a very obvious dividing line at the junction of the high and low beams, resulting in a noticeable defect in the high beam's shape. Furthermore, the overall beam pattern of the high beam appears higher on distant screens, significantly impacting driving safety.
[0004] In addition, the traditional top-and-bottom arrangement of high and low beam focusing modules has its own limitations. In particular, when the top and bottom openings of the optical module are small, the efficiency and brightness of the module will be greatly reduced, so it cannot adapt to the current development trend of increasingly narrow top and bottom openings of optical modules. Summary of the Invention
[0005] To address the above problems, the technical solution adopted in this application is as follows:
[0006] This application discloses a light-emitting system, including:
[0007] The low beam unit is used to collimate and form a low beam that is emitted at an angle downwards. The low beam unit is located above and behind the baffle.
[0008] The first high beam unit is used to collimate and form a first high beam ray emitted directly forward; the first high beam unit is arranged side by side on the left and right sides of the low beam unit in the horizontal direction, and the first high beam unit is at least partially at the same height as the baffle.
[0009] Baffles are spaced apart on the light-emitting side of the low beam unit and close to the bottom edge of the low beam unit;
[0010] An external lens is disposed on the side of the baffle away from the near beam unit, including a converging imaging lens and a far beam non-focal point offset lens disposed on the left and right sides of the converging imaging lens in the horizontal direction.
[0011] The converging imaging lens is opposite to the near beam unit and is used to converge the near beam to form a near beam pattern; the two far beam unfocused offset lenses are directly opposite the two first far beam units and are used to shift the corresponding two sets of first far beams toward each other to form a far beam pattern.
[0012] Compared with the prior art, this application has at least the following advantages:
[0013] In high beam mode, compared to the scheme of tilting upwards to focus the light to form the high beam pattern, this application adopts a novel method of emitting light directly forward to form the high beam. That is, the first high beam unit on both sides of the low beam unit respectively forms the first high beam light rays to be emitted directly forward. After being horizontally deflected by the high beam unfocused offset lens, a circular bright spot of high beam is formed. The high beam unfocused offset lens on both sides is only used to deflect the first high beam light rays on the left and right sides in a direction closer to each other, and does not have the function of focusing or imaging. Since the light emission direction of the first high beam unit is directly forward and at least part of the first high beam unit is at the same height as the baffle, in high beam mode, when the high beam and low beam are turned on at the same time, the circular bright spot of high beam formed by the two first high beam units emitted directly forward can just cover the horizontal dividing line formed by the baffle, thereby visually eliminating the horizontal dividing line at the junction of high and low beams, and the high beam pattern is more complete.
[0014] Compared to the solution of tilting upwards to focus light to form a high beam pattern, this application adopts a new method of emitting light forward to form a high beam, and at least part of the first high beam module is at the same height as the baffle. As a result, the forward-facing high beam pattern area formed by this application will be positioned lower on the distant screen. According to actual tests, in the CNCAP rating, the high beam score point P5 drops to near or even below the cutoff line, which can correspondingly improve the score and enhance driving safety.
[0015] As an optional implementation, the upper edge of the light-emitting surface of the first high beam unit is lower than the upper edge of the low beam unit, and the center of the light-emitting surface of the first high beam unit is at the same height as the baffle.
[0016] As an optional implementation, it further includes: a second far-beam unit for collimating and forming a second far-beam emitted at an upward angle; the converging imaging lens is also opposite to the second far-beam unit for converging the second far-beam to form a second far-beam pattern.
[0017] As an optional implementation, the slope of the connection between the light-emitting surface of the converging imaging lens and the light-emitting surface of the far-beam non-focal offset lens is consistent, and the connection is smoothly transitioned.
[0018] As an optional implementation, the light-incident surface and the light-outcident surface of the high beam non-focus shifting lens are respectively forward-convex inclined curved surfaces, and the light-incident surface and the light-outcident surface of the high beam non-focus shifting lens are not parallel.
[0019] As an alternative implementation, the thickness of the far-beam unfocused offset lens gradually increases in the front-to-back direction along the width from the center of the outer lens to the side.
[0020] As an optional implementation, the angle between the incident surface of the high beam non-focus shifting lens and the front-back direction is smaller than the angle between the emitting surface of the high beam non-focus shifting lens and the front-back direction.
[0021] As an optional implementation, the ratio of the horizontal dimension to the vertical dimension of the outer lens is greater than or equal to 4:1.
[0022] As an optional implementation, the first high beam unit includes a circular condenser, the light-emitting surface of which faces directly forward and is opposite to the high beam non-focal offset lens, for collimating and forming the first high beam ray emitted directly forward.
[0023] As an optional implementation, the low beam unit includes a plurality of low beam concentrators arranged side by side in a horizontal direction.
[0024] As an optional implementation, the second high beam unit includes a plurality of high beam concentrators arranged side by side along the horizontal direction.
[0025] As an optional implementation, the two first high beam units are located on the left and right outer sides of the baffle in the width direction, and do not overlap with the projection of the baffle in the vertical plane perpendicular to the first high beam rays.
[0026] This application also discloses a vehicle lamp, which is equipped with the light-emitting system described in any of the foregoing embodiments.
[0027] This application also discloses a vehicle including the headlights described in any of the foregoing embodiments.

[0050] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0051] Integrated high and low beam modules have evolved into various design forms, with the condenser + baffle + lens configuration being the most widely used. This design typically uses the condenser as a primary optical element to focus the energy of the LEDs and distribute it on the baffle. A focusing lens then images the shape of the baffle. For example, the low beam lens 1 and the high beam lens 2 are positioned on the upper and lower sides of the baffle 3, respectively. In low beam mode, the light emitted from the low beam source 1' is focused by the low beam lens 1 and emitted diagonally downwards, then collimated by the secondary lens 4 to form low beam, projecting a low-positioned low beam pattern at a distance. In high beam mode, the low beam remains lit, while the light emitted from the high beam source 2' is focused by the high beam lens 2 and emitted diagonally upwards, then collimated by the secondary lens 4 to form high beam, projecting a high beam pattern at a distance.
[0052] When high beams are on and low beams are on simultaneously, there is a very obvious dividing line at the junction of the high and low beams, resulting in a noticeable defect in the high beam pattern. Furthermore, the overall beam pattern of the high beam appears higher on distant screens, which also significantly impacts driving safety. This issue urgently needs to be addressed.
[0053] refer to Figures 2-5 This application provides a light-emitting system, comprising:
[0054] The low beam unit 100 is used to collimate and form a low beam that is emitted at an angle downwards. The low beam unit 100 is located above and behind the baffle 300.
[0055] The first high beam unit 210 is used to collimate and form a first high beam ray emitted forward; the first high beam unit 210 is arranged side by side on the left and right sides of the low beam unit 100 in the horizontal direction, and at least part of the first high beam unit 210 is at the same height as the baffle 300.
[0056] Baffles 300 are spaced apart on the light-emitting side of the low beam unit 100 and close to the bottom edge of the low beam unit 100;
[0057] The outer lens 400 is disposed on the side of the baffle 300 away from the near beam unit 100, and includes a converging imaging lens 410 and a far beam non-focus shifting lens 420 disposed on the left and right sides of the converging imaging lens 410 in the horizontal direction.
[0058] The converging imaging lens 410 is opposite to the near beam unit 100 and is used to converge the near beam to form a near beam pattern; the two far beam non-focus shifting lenses 420 are directly opposite the two first far beam units 210 and are used to shift the corresponding two sets of first far beams toward each other to form a far beam pattern.
[0059] In actual operation, in low beam mode, the low beam unit 100 collimates to form a low beam emitted at an angle downwards. After passing through the baffle 300 to form a horizontal dividing line, a low beam pattern is formed at a position on the lower part of the screen at a distance (the low beam cut-off line is located at the upper edge of the low beam pattern).
[0060] In high beam mode, compared to the scheme of tilting upwards to focus the light to form a high beam pattern, this application adopts a novel method of emitting light directly forward to form a high beam. Specifically, the first high beam units 210 on both sides of the low beam unit 100 respectively generate first high beam rays that are emitted directly forward. After being horizontally deflected by the high beam non-focal point shifting lens 420, they form a circular bright spot of high beam (the first high beam rays basically do not pass through the baffle 300). The high beam non-focal point shifting lenses 420 on both sides are only used to shift the first high beam rays on the left and right sides towards each other, and do not have focusing or imaging functions (e.g., ...). Figure 5 Since the light emission direction of the first high beam unit 210 is directly forward and at least part of the first high beam unit 210 is at the same height as the baffle 300, when the high beam and low beam are turned on at the same time in high beam mode, the circular bright spot of the high beam formed by the two first high beam units 210 emitting light directly forward can just cover the horizontal dividing line formed by the baffle 300, thereby visually eliminating the horizontal dividing line at the junction of high and low beams, and making the high beam shape more complete;
[0061] Compared to the solution of tilting upwards to focus light to form a high beam pattern, this application adopts a new method of emitting light forward to form a high beam, and at least part of the first high beam module is at the same height as the baffle 300. As a result, the forward-facing high beam pattern area formed by this application will be positioned lower on the distant screen. According to actual tests, in the CNCAP rating, the high beam score point P5 drops to near or even below the cutoff line, which can correspondingly improve the score and enhance driving safety.
[0062] The converging imaging lens 410's inherent converging characteristic results in edge aberration at the interface with air, leading to significant chromatic aberration. However, the two focal-shifting lenses 420 on either side of the converging imaging lens 410 are integrally connected to its sides. By fixing these focal-shifting lenses (which lack converging function) to both sides of the converging imaging lens 410, the lens itself no longer has an interface with air, thus eliminating edge aberration and resolving the chromatic aberration problem.
[0063] In this application, the first high beam unit 210 is arranged side by side on the left and right sides of the low beam unit 100 in the horizontal direction, and the high beam non-focus shift lens 420 is arranged on the left and right sides of the converging imaging lens 410 in the horizontal direction. Therefore, the space in the horizontal width direction of the optical module can be fully utilized, which is particularly suitable for the case where the aspect ratio of the module lens size exceeds 4:1. In this case, the size utilization rate of the outer lens 400 can reach 100%. The first high beam unit 210 is arranged side by side on the left and right sides of the low beam unit 100 in the horizontal direction. The emission from both sides greatly increases the area of the entire high beam pattern formed, thereby improving the efficiency and brightness of the narrow aperture optical module.
[0064] It should be noted here that: Figure 3 , Figure 4 Based on this, the forward and backward directions described in this application correspond to Figure 3 The left and right directions described in this application correspond to the left and right directions, respectively. Figure 3 The upward and downward directions, as described in this application, respectively correspond to the downward and upward directions. Figure 4 The up and down directions.
[0065] refer to Figure 4 In some embodiments, the upper edge of the light-emitting surface of the first high beam unit 210 is at a height lower than the upper edge of the low beam unit 100, and the center of the light-emitting surface of the first high beam unit 210 is at the same height as the baffle 300.
[0066] In this embodiment, the center of the light-emitting surface of the first high beam unit 210 is low and at the same height as the baffle 300. The high beam rays formed by the two first high beam units 210 are emitted straight forward. After being horizontally deflected by the high beam non-focus offset lens 420, the center of the circular bright spot formed by the high beam falls exactly on the horizontal dividing line formed by the baffle 300, thus completely covering the horizontal dividing line formed by the baffle 300. Visually, the horizontal dividing line at the junction of the high and low beams is completely invisible, and the high beam shape appears more complete. Furthermore, compared with the traditional design, the method of emitting light straight forward to form high beams is adopted. The height of the upper edge of the light-emitting surface of the first high beam unit 210 is lower than the upper edge of the low beam unit 100, and the center height of the light-emitting surface of the first high beam module is the same as the height of the baffle 300. The overall position of the high beam area formed straight forward on the distant screen is also lower (according to actual measurement, in the CNCAP rating, the high beam scoring point P5 is located at or below the cutoff line), further improving the rating score and night driving safety.
[0067] refer to Figure 2 and Figure 8In some embodiments, it further includes: a second far-beam unit 220 for collimating and forming a second far-beam emitted at an upward angle; the converging imaging mirror 410 is also opposite to the second far-beam unit 220 and is used to converge the second far-beam to form a second far-beam pattern.
[0068] Specifically, in high beam mode, the second high beam unit 220 collimates to form a second high beam that is emitted at an angle upwards. After passing through the baffle 300 to form a horizontal dividing line, a second high beam pattern is formed at a position near the top of the screen at a distance (the high beam cutoff line is at the lower edge of the high beam pattern). In this case, the second high beam pattern and the high beam circular bright spot formed by the first high beam unit 210 together form the high beam pattern, which can increase the area and brightness of the high beam pattern.
[0069] refer to Figure 6 In some embodiments, the slope of the connection between the light-emitting surface of the converging imaging lens 410 and the light-emitting surface 422 of the far-beam non-focal offset lens 420 is consistent, and there is a smooth transition at the connection.
[0070] The above settings can make the converging imaging lens 410 and the far-beam non-focus shifting lens 420 appear uniform in overall appearance.
[0071] Since the converging imaging lens is an externally convex lens, when the slope of the connecting part of the light-emitting surface of the far beam unfocused offset lens 420 is consistent and smoothly transitioned, it means that the light-emitting surface 422 of the far beam unfocused offset lens 420 is also an inclined surface at an acute angle to the front-back direction. In this case, if the light-incident surface 421 of the far beam unfocused offset lens 420 is designed to be perpendicular to the front-back direction, the light will diffuse outward directly from the light-emitting surface of the far beam unfocused offset lens 420 and cannot form far beam. Therefore, it is necessary to adjust the light-incident surface 421 of the far beam unfocused offset lens 420 to make it tilted. Tilting the light-incident surface can ensure that the corresponding two sets of first far beam rays are shifted in a direction closer to each other, rather than diffused outward. Therefore, based on the above, as an example, the light-incident surface 421 and the light-outcident surface 422 of the high beam non-focus offset lens 420 are respectively forward-convex inclined curved surfaces, and the light-incident surface 421 and the light-outcident surface 422 of the high beam non-focus offset lens 420 are not parallel to each other, so that the first high beam rays emitted by the two first high beam units on the left and right respectively are refracted twice by the corresponding inclined light-incident surface 421 and inclined light-outcident surface 422 and then emitted to the side closer to each other.
[0072] Specifically, in this example, the light-incident surface 421 and the light-outcident surface 422 of the high-beam non-focal point shifting lens 420 are not parallel, causing the front-to-back thickness dimension between the light-incident surface and the light-outcident surface of the high-beam non-focal point shifting lens 420 to gradually change in the width direction of the optical module (e.g., Figure 6In the middle of the outer lens 400, the thickness of the far-beam non-focal point shifting lens 420 gradually increases in the front-back direction along the width from the middle to the side. That is, the angle between the light-incident surface 421 and the front-back direction is smaller than the angle between the light-outcrystal surface 422 and the front-back direction. This design allows the first far-beam rays that are incident directly in front of each other to be refracted twice by the inclined light-incident surface 421 and the inclined light-outcrystal surface 422 and then emitted towards each other, thus shifting towards each other. In other words, the non-parallel design between the inclined light-incident surface 421 and the inclined light-outcrystal surface 422 of the far-beam non-focal point shifting lens 420 allows the first far-beam rays on the left and right sides to shift towards each other and merge to form a far-beam pattern.
[0073] refer to Figure 2 In some embodiments, the ratio of the horizontal dimension to the vertical dimension of the outer lens 400 is greater than or equal to 4:1.
[0074] Specifically, the first high-beam unit 210 is arranged side-by-side on the left and right sides of the low-beam unit 100 in the horizontal direction. The emission from both sides greatly increases the area of the entire high-beam pattern, thereby improving the efficiency and brightness of the narrow-aperture optical module, making it particularly suitable for optical modules with a large aspect ratio. Experiments have shown that when the aspect ratio of the outer lens 400 exceeds 4:1, the size utilization rate of the outer lens 400 can reach 100%, thus maximizing the luminous efficiency.
[0075] refer to Figure 2 In some embodiments, the first high beam unit 210 includes a circular condenser with its light-emitting surface facing forward and opposite to the high beam unfocused offset lens 420, for collimating the formation of the first high beam ray emitted forward.
[0076] Specifically, the circular condensers on both sides can converge the light emitted from the rear light source to form the first high beam and emit it directly in front of it. Then, the high beam is further horizontally shifted towards each other by the high beam non-focus offset lens 420 to form a circular high beam spot. The circular high beam pattern is regular and the visual light effect is better.
[0077] refer to Figure 2 In some embodiments, the low beam unit 100 includes a plurality of low beam concentrators arranged side by side in a horizontal direction. Further, there are seven low beam concentrators, with the central one as the center and the side concentrators arranged symmetrically from left to right. This horizontally symmetrical arrangement of the low beam concentrators ensures that the collimated light emitted is symmetrical in the horizontal direction, resulting in a regular beam pattern.
[0078] refer to Figure 9In some embodiments, the second high-beam unit 220 includes a plurality of high-beam concentrators arranged side by side along a horizontal direction. Further, there are three high-beam concentrators, with the middle one as the center and the side high-beam concentrators arranged symmetrically from left to right. This horizontally symmetrical arrangement of the high-beam concentrators ensures that the collimated light emitted is symmetrical in the horizontal direction, resulting in a regular emitted light pattern.
[0079] refer to Figure 3 In some embodiments, the projections of the first high beam unit 210 and the baffle 300 in a vertical plane perpendicular to the first high beam ray do not overlap. That is, the two first high beam units 210 are located on the left and right outer sides of the baffle 300 in the width direction, respectively, and the first high beam ray collimated by the first high beam unit 210 will not pass through the baffle 300, resulting in a more regular light pattern.
