Description

Technical Field

[0001] This invention relates to vehicle lights, specifically, to a lighting module. Furthermore, this invention also relates to a vehicle light. Background Technology

[0002] Currently, to achieve intelligent light patterns, lighting modules typically require two rows of LEDs arranged on the circuit board, used for the upper and lower light patterns respectively, such as... Figure 1 As shown.

[0003] The upper row of LEDs 2001 and the lower row of LEDs 2002 each use silicone pin-type condensers 2003 to modulate the light, and the light-emitting surfaces of the silicone pin-type condensers 2003 converge at the focal plane of the lens 2004, achieving a double-row light pattern. The main disadvantage of the pin-type solution is that the divergence angle of the silicone pin-type condensers used is relatively large, requiring a large aperture of the lens 2004 to achieve good brightness; common sizes are 50mm×70mm or 40mm×60mm. This large aperture of the lens 2004 limits the design of automotive front combination lights and is not suitable for the trend of increasingly narrow lens apertures in headlight design. At the same time, the pin-type solution requires two silicone pin-type condensers, necessitating more structural components for positioning, support, and installation.

[0004] Therefore, this solution has the disadvantages of high silicone cost, numerous parts, complex installation, and high installation cost.

[0005] In view of this, it is necessary to design a lighting module that can overcome the above-mentioned technical difficulties and effectively solve or alleviate the above-mentioned technical defects. Summary of the Invention

[0006] One of the objectives of this invention is to provide a lighting module with a narrower opening, which is beneficial for the design of vehicle lights while reducing parts and installation costs.

[0007] The second objective of this invention is to provide a vehicle lamp with a narrow opening in the lighting module, which is beneficial for the lamp's design while reducing parts and installation costs.

[0008] To achieve the above objectives, the present invention provides a lighting module comprising a light source module, a reflector, and a light-emitting element arranged sequentially along the light transmission direction. The reflector includes a plurality of first reflectors and a plurality of second reflectors arranged laterally. The light source module includes a plurality of first light-emitting units corresponding to the first reflectors and a plurality of second light-emitting units corresponding to the second reflectors. The light beam emitted by the first light-emitting unit is adapted to be reflected by the corresponding first reflector and then projected by the light-emitting element to form a first light pattern. The light beam emitted by the second light-emitting unit is adapted to be reflected by the corresponding second reflector and then projected by the light-emitting element to form a second light pattern. The first light pattern and the second light pattern extend laterally and are arranged vertically.

[0009] Specifically, the light-emitting element includes a first light-emitting section and a second light-emitting section arranged in a transverse direction. The first light-emitting section is arranged corresponding to a plurality of first reflectors and is configured to project the reflected light from the plurality of first reflectors to form a first light pattern. The second light-emitting section is arranged corresponding to a plurality of second reflectors and is configured to project the reflected light from the plurality of second reflectors to form a second light pattern.

[0010] Specifically, the lower edge of the reflecting surface of the first reflector is higher than the lower edge of the reflecting surface of the second reflector; and / or the upper edge of the reflecting surface of the second reflector is lower than the upper edge of the reflecting surface of the first reflector.

[0011] Specifically, the longitudinal distance between the focal point of the first light-emitting part and the light source module is smaller than the longitudinal distance between the focal point of the second light-emitting part and the light source module.

[0012] Specifically, the first light-emitting part includes a plurality of first light-emitting units, the second light-emitting part includes a plurality of second light-emitting units, and the plurality of first light-emitting units and the plurality of second light-emitting units are arranged side by side in the transverse direction; or, the plurality of first light-emitting units and the plurality of second light-emitting units are arranged alternately in the transverse direction.

[0013] Specifically, multiple first light-emitting units are respectively configured to correspond to one or more first reflectors. The first light-emitting unit is configured to project the reflected light pattern of the corresponding first reflector to form a first sub-light pattern. The first light pattern includes the first sub-light patterns projected by multiple first light-emitting units.

[0014] Multiple second light-emitting units are respectively arranged corresponding to one or more second reflectors. The second light-emitting units are configured to project the reflected light from the corresponding second reflector to form a second sub-light pattern. The second light pattern includes the second sub-light patterns projected by the multiple second light-emitting units.

[0015] Preferably, the plurality of first sub-light patterns are arranged laterally in an alternating pattern to form a complete first light pattern;

[0016] Multiple second sub-light patterns are arranged laterally in an alternating pattern to form a complete second light pattern.

[0017] Specifically, the light-emitting surfaces of the first light-emitting part and the second light-emitting part form a light-emitting surface, and the light-emitting surface of the light-emitting element is a convex curved surface formed by sweeping a convex curve along a first sweep line, wherein the first sweep line is a straight line or arc extending laterally.

[0018] Specifically, the light-incident surface of the first light-emitting unit and the light-incident surface of the second light-emitting unit are calculated based on the light-emitting surface of the light-emitting element.

[0019] Preferably, the lighting module further includes a light-blocking plate, which is disposed between the reflector and the light-emitting element, and the light-blocking plate is arranged at the boundary of each first light-emitting unit and / or each second light-emitting unit.

[0020] Specifically, the lighting module is adapted to provide a high beam pattern, wherein the upper edge of the second beam pattern is configured to be flush with the high shoulder of the low beam pattern.

[0021] Preferably, the first reflectors and the second reflectors are integrally formed.

[0022] Preferably, the first light-emitting unit and the second light-emitting unit are controlled separately so that the lighting module provides an adaptive high beam pattern.

[0023] A second aspect of the present invention provides a vehicle lamp, which includes a lighting module of any of the above-described technical solutions.

[0024] Through the above technical solution, the light beams emitted by several first light-emitting units of the lighting module of this application can be reflected by corresponding first reflectors and then projected by light-emitting elements to form a first light pattern. The light beams emitted by several second light-emitting units are suitable for being reflected by corresponding second reflectors and then projected by light-emitting elements to form a second light pattern. The first and second light patterns extend laterally, and the first ADB light pattern and the second ADB light pattern are arranged vertically, thereby forming a double-row light pattern arranged vertically. The desired light pattern is achieved by controlling the on / off state of the first light-emitting units and / or the second light-emitting units. Furthermore, compared with the existing vertically arranged silicone needle-type condensers, the horizontally arranged first and second reflectors of this application can make the divergence angle of the emitted light smaller, the longitudinal dimension of the light-emitting element smaller, and the opening of the light-emitting element narrower. This is beneficial to the design of the vehicle headlights. At the same time, the reflector installation requires fewer parts, making installation simple and effectively reducing part costs and installation costs. Attached Figure Description

[0048] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The detailed description of the following embodiments and the accompanying drawings are used to illustrate the principles of the present invention by way of example, but should not be used to limit the scope of the present invention. The present invention can be implemented in many different forms and is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.

[0050] It should be noted that, in the description of this invention, unless otherwise stated, "a plurality of" means two or more. It should also be noted that, for ease of description and simplification, the orientation of the headlight module is generally the same as that of the headlight in actual use on a vehicle; for example, the lens is in front, and correspondingly, the primary optical element (e.g., a reflector) is behind. The lateral arrangement of the individual optical systems means that the individual optical systems are arranged approximately along the left-right direction, and the vertical arrangement means approximately along the up-down direction. In the description of this application, the indicated orientations or positional relationships are only for ease of description and simplification, 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, they should not be construed as limitations on this application. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0051] Furthermore, the terms "first," "second," and similar terms used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different parts. Terms such as "comprising" or "including" mean that the element preceding the term encompasses the element listed after the term, and do not exclude the possibility of encompassing other elements as well.

[0052] It should also be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention depending on the specific circumstances. When a specific device is described as being located between a first device and a second device, an intermediary device may or may not be present between the specific device and the first or second device.

[0053] All terms used in this invention have the same meaning as understood by one of ordinary skill in the art to which this invention pertains, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and not as idealized or highly formalized, unless expressly defined herein.

[0054] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0055] To achieve the above objectives, this application provides a lighting module, see below. Figures 3-12The lighting module includes a light source module 1, a reflector 2, and a light-emitting element 3 arranged sequentially along the light transmission direction. The reflector 2 includes a plurality of first reflectors 201 and a plurality of second reflectors 202 arranged laterally. The light source module includes a plurality of first light-emitting units 101 corresponding to the first reflectors 201 and a plurality of second light-emitting units 102 corresponding to the second reflectors 202. The first light-emitting units 101 and the second light-emitting units 102 can be LEDs, laser light sources, or other types of light sources. Those skilled in the art can choose to set them according to the actual situation, and this application does not limit them. The light beam emitted from the first light-emitting unit 101 is adapted to be reflected by the corresponding first reflector 201 and then projected by the light-emitting element 3 to form a first light pattern. The light beam emitted from the second light-emitting unit 102 is adapted to be reflected by the corresponding second reflector 202 and then projected by the light-emitting element 3 to form a second light pattern. The first light pattern and the second light pattern extend laterally and are arranged vertically, thereby forming a double-row light pattern arranged vertically. The desired lighting pattern is achieved by controlling the brightness of the first light-emitting unit 101 and / or the second light-emitting unit 102. Compared to the vertically arranged condensers and light sources of the prior art, the first reflector 201 and the second reflector 202 of this application are arranged horizontally, with the first light-emitting unit 101 corresponding to the first reflector 201 and the second light-emitting unit 102 corresponding to the second reflector 202. This results in a smaller divergence angle of the emitted light and a smaller light-transmitting area required in the vertical direction for the light-emitting element 3. Consequently, the light-emitting element 3 can be made narrower. In some specific embodiments, the vertical opening height of the light-emitting element 3 of this application can be greater than or equal to 10 mm and less than or equal to 30 mm, which is beneficial for the narrow-aperture design of vehicle lights. At the same time, the reflectors required for the dual-row light pattern are fewer in number, making installation simple and effectively reducing component and installation costs.

[0056] Specifically, the horizontal direction refers to the left-right direction when the lighting module is installed on the vehicle's headlights and the vehicle is on a horizontal plane (such as the ground), and the vertical direction refers to the up-down direction when the lighting module is installed on the vehicle's headlights and the vehicle is on a horizontal plane (such as the ground). The "up-down" direction mentioned in the vertical arrangement of the first and second light patterns refers to the direction perpendicular to the horizontal direction when the first and second light patterns are projected onto the ground or wall.

[0057] Specifically, the first light pattern is a light pattern formed by the projection and combination of a plurality of first light-emitting units 101 through a first reflector 201 and a light-emitting element 3; the second light pattern is a light pattern formed by the projection and combination of a plurality of second light-emitting units 102 through a second reflector 202 and a light-emitting element 3.

[0058] As a specific implementation method, such as Figure 3 , Figure 4 and Figure 10As shown, the light-emitting element 3 includes a first light-emitting section 301 and a second light-emitting section 302 arranged laterally. The first light-emitting section 301 is disposed corresponding to a plurality of first reflectors 201 and is configured to project the reflected light rays from the plurality of first reflectors 201 to form a first light pattern. The second light-emitting section 302 is disposed corresponding to a plurality of second reflectors 202 and is configured to project the reflected light rays from the plurality of second reflectors 202 to form a second light pattern. In some specific embodiments, the focal point of the first light-emitting section 301 is a first focal point 401, and the focal point of the second light-emitting section 302 is a second focal point 402. By adjusting the position of the first focal point 401 relative to the corresponding first reflector 201 in the horizontal and vertical directions, the position of the first light pattern formed by the reflected light rays from the corresponding first reflector 201 projected by the first light-emitting section 301 in the horizontal (left-right) and vertical (up-down) directions is adjusted. Similarly, by adjusting the position of the second focal point 402 relative to the corresponding second reflector 202 in the horizontal and vertical directions, the position of the first light pattern formed by the first light-emitting section 301 is adjusted. The positions of the second light pattern formed by the reflected light from the second reflector 202 and the second light-emitting part 302 in the horizontal (left-right direction) and vertical (up-down direction) directions are determined to ensure that the light patterns formed by the first light-emitting units 101 projected by the first reflector 201 and the light-emitting element 3 are arranged horizontally to form a first light pattern that meets the design requirements, and to ensure that the light patterns formed by the second light-emitting units 102 projected by the second reflector 202 and the light-emitting element 3 are arranged horizontally to form a second light pattern that meets the design requirements, thereby ensuring that the vertical arrangement of the first light pattern and the second light pattern meets the design requirements.

[0059] For example, such as Figure 6 and Figure 7 As shown, pixels U1-U10 represent the pixel light patterns projected by the 10 first light-emitting units 101 that make up the first light pattern in the double-row light pattern, and pixels D1-D10 represent the pixel light patterns projected by the 10 second light-emitting units 102 that make up the second light pattern in the double-row light pattern. The number of first light-emitting units 101 and second light-emitting units 102 in this application is not limited thereto.

[0060] In some specific embodiments, such as Figure 6 As shown, the left and right boundaries of the first and second light patterns are aligned. In other specific embodiments, such as... Figure 7 The first and second light patterns can be staggered, and the amount of stagger can be adjusted according to actual needs, such as overlapping by 0.5, 1, 1.5 or 2 pixels of light pattern width. This application is not limited to this.

[0061] like Figure 3 , Figure 4 , Figure 10 and Figure 11As shown, in one specific embodiment, the lower edge of the reflective surface of the first reflector 201 is higher than the lower edge of the reflective surface of the second reflector 202; in another specific embodiment, the upper edge of the reflective surface of the second reflector 202 is lower than the upper edge of the reflective surface of the first reflector 201; in yet another specific embodiment, the lower edge of the reflective surface of the first reflector 201 is higher than the lower edge of the reflective surface of the second reflector 202, and the upper edge of the reflective surface of the second reflector 202 is lower than the upper edge of the reflective surface of the first reflector 201. In some specific embodiments, the vertical height of the first reflector 201 is greater than the vertical height of the second reflector 202, so that the vertical height of the first light pattern is greater than the vertical height of the second light pattern, thereby meeting the light pattern requirements of the lighting module.

[0062] As a specific implementation method, such as Figure 5 As shown, by adjusting the positions of the first focal point 401 and / or the second focal point 402, the longitudinal distance between the first focal point 401 and the light source module 1 is made smaller than the longitudinal distance between the second focal point 402 and the light source module 1. This allows the lower side of the first light pattern and the upper side of the second light pattern to overlap by a predetermined pixel width, thereby improving the overall uniformity of the dual-row light patterns. Furthermore, the first focal point 401 and / or the second focal point 402 can be located near the root of the corresponding reflector 2 on the side closest to the light source module, or the first focal point 401 and / or the second focal point 402 can be located above the root of the corresponding reflector 2 on the side closest to the light source module. In a preferred embodiment, the first focal point 401 is located near the root of the corresponding reflector 2 on the side closest to the light source module, and the second focal point 402 can be located above the root of the corresponding reflector 2 on the side closest to the light source module. This allows the first and second light patterns to be further arranged vertically, resulting in a better connection effect after the first and second light patterns are superimposed, and the upper boundary of the second light pattern is flush with the high shoulder of the near-light cutoff line.

[0063] In some specific embodiments, the first light-emitting section 301 includes a plurality of first light-emitting units 3011, and the second light-emitting section 30) includes a plurality of second light-emitting units 3021, with the plurality of first light-emitting units 3011 and the plurality of second light-emitting units 3021 arranged side by side in the transverse direction. Figure 2 Taking four light-emitting units as an example, light-emitting units b1 and b2 are first light-emitting units 3011, and light-emitting units b3 and b4 are second light-emitting units 3021. In other embodiments, multiple first light-emitting units 3011 and multiple second light-emitting units 3021 are arranged in a staggered manner along the lateral direction. Figure 2Taking four light-emitting units as an example, light-emitting units b1 and b3 are first light-emitting units 3011, and light-emitting units b2 and b4 are second light-emitting units 3021. Correspondingly, the plurality of first reflectors 201 corresponding to light-emitting units b1 and b3, and the plurality of second reflectors 202 corresponding to light-emitting units b2 and b4 are also arranged horizontally in a staggered manner; the plurality of first light-emitting units 101 corresponding to light-emitting units b1 and b3, and the plurality of second light-emitting units 102 corresponding to light-emitting units b2 and b4 are also arranged horizontally in a staggered manner. In the embodiment where the plurality of first light-emitting units 3011 and the plurality of second light-emitting units 3021 are arranged horizontally in a staggered manner, as long as the relative positions of the corresponding focal points a1, a2, a3, and a4 and the corresponding reflectors are adjusted so that a double-row light pattern can be formed, the arrangement order of the plurality of first light-emitting units 3011 and the plurality of second light-emitting units 3021 in this application can be freely adjusted.

[0064] In some specific embodiments, a plurality of first light-emitting units 3011 are respectively disposed corresponding to one or more first reflectors 201. The first light-emitting unit 3011 is configured to project the reflected light from the corresponding first reflector 201 to form a first sub-light pattern. The first light pattern includes the first sub-light pattern projected by the plurality of first light-emitting units 3011. The second light-emitting part 302 includes a plurality of second light-emitting units 3021. The plurality of second light-emitting units 3021 are respectively disposed corresponding to one or more second reflectors 202. The second light-emitting unit 3021 is configured to project the reflected light from the corresponding second reflector 202 to form a second sub-light pattern. The second light pattern includes the second sub-light pattern projected by the plurality of second light-emitting units 3021.

[0065] In some specific embodiments, multiple first sub-light patterns can be arranged side by side in the horizontal direction, and multiple second sub-light patterns can also be arranged side by side in the horizontal direction.

[0066] In some specific embodiments, the first sub-light pattern formed by the reflected light from a single first reflector 201 through the first light-emitting unit 3011 and the second light pattern formed by the reflected light from a single second reflector 202 through the second light-emitting unit 3021 may exhibit wavy brightness variations, resulting in poor illumination of the lighting module. As a preferred embodiment, the bright and dark areas of multiple first sub-light patterns are arranged laterally in an alternating pattern to form a complete first light pattern. That is, the bright area of ​​first sub-light pattern one can illuminate the dark area of ​​first sub-light pattern two to connect adjacent bright areas of first sub-light pattern one, thereby forming a complete first light pattern. Furthermore, the bright and dark areas of multiple second sub-light patterns can also be arranged laterally in an alternating pattern to form a complete second light pattern. This application can implement many more variations, which will not be elaborated here.

[0067] Taking two first light-emitting units 3011 and two second light-emitting units 3021 as examples. One of the two first light-emitting units 3011 projects a plurality of pixel light patterns to form a first sub-light pattern 1 with alternating brightness and darkness, while the other projects a plurality of pixel light patterns to form a second sub-light pattern with alternating brightness and darkness. The second sub-light pattern 2 is configured to project the bright areas of the second sub-light pattern 2 onto the dark areas of the first sub-light pattern 1, thereby forming a complete first light pattern. Similarly, one of the two second light-emitting units 3021 projects a plurality of pixel light patterns to form a second sub-light pattern 1 with alternating brightness and darkness, while the other projects a plurality of pixel light patterns to form a second sub-light pattern 2 with alternating brightness and darkness. The second sub-light pattern 2 is configured to project the bright areas of the second sub-light pattern 2 onto the dark areas of the second sub-light pattern 1, thereby forming a complete second light pattern. By superimposing the bright area of ​​the second sub-light pattern onto the dark area of ​​the first sub-light pattern, the brightness of the formed first light pattern is made more uniform. Similarly, by superimposing the bright area of ​​the second sub-light pattern onto the dark area of ​​the second sub-light pattern, the brightness of the formed second light pattern is made more uniform, thereby improving the overall lighting effect of the dual-row light patterns formed by the lighting model. In other embodiments, it is understood that the number of first light-emitting units 3011 may be greater than two, so as to project the reflected light from the corresponding first reflector 201 to form multiple alternating bright and dark first sub-light patterns, and to superimpose the multiple first sub-light patterns to form a first light pattern with more uniform brightness. The number of second light-emitting units 3021 may be greater than two, so as to project the reflected light from the corresponding second reflector 202 to form multiple alternating bright and dark second sub-light patterns, and to superimpose the multiple second sub-light patterns to form a second light pattern with more uniform brightness.

[0068] As a specific way of stating facts, such as Figure 2 , Figure 3 and Figure 10 As shown, the light-emitting element 3 can be a lens. The light-emitting surfaces of the first light-emitting portion 301 and the second light-emitting portion 302 of the light-emitting element 3 form a light-emitting surface 303. The light-emitting surface 303 can be, for example, a smooth curved surface. In some specific embodiments, the light-emitting surface 303 is a convex curved surface formed by sweeping a convex curve along a first sweep line, where the first sweep line is a straight line or arc extending laterally, so that the light-emitting surface 303 can converge and collimate in the vertical direction, thereby enabling the imaging of the light beam reflected by the mirror.

[0069] In some embodiments, the light-incident surface of the first light-emitting unit 3011 and the light-incident surface of the second light-emitting unit 3021 are calculated based on the light-emitting surface of the light-emitting element 3.

[0070] As a specific implementation method, such as Figure 2 , Figure 3 and Figure 10As shown, the light-incident surface of the first light-emitting unit 3011 is a convex surface formed by a convex curve sweeping along a second sweep line, and the second sweep line is a straight line or arc extending vertically; the light-incident surface of the second light-emitting unit 3021 is a convex surface formed by a convex curve sweeping along a third sweep line, and the third sweep line is a straight line or arc extending vertically, so that the light-incident surfaces of the first light-emitting unit 3011 and the second light-emitting unit 3021 have a converging and collimating effect in the horizontal direction.

[0071] The light-emitting surface 303 of the light-emitting element 3 is designed according to appearance requirements and vertical convergence requirements. The light-incident surface of the first light-emitting unit 3011 is calculated using a freeform surface algorithm based on the position of the light-emitting surface 303 and the corresponding first focal point 401. The light-incident surface of the second light-emitting unit 3021 is calculated using a freeform surface algorithm based on the position of the light-emitting surface 303 and the corresponding second focal point 402. In some embodiments, the lateral dimension of the light-incident surface of the first light-emitting unit 3011 can be set to be different from the lateral dimension of the light-incident surface of the second light-emitting unit 3021. For example, the lateral dimension of the light-incident surface of the first light-emitting unit 3011 is larger than the lateral dimension of the light-incident surface of the second light-emitting unit 3021, thereby making the brightness of the first light pattern greater than the brightness of the second light pattern.

[0072] In a preferred embodiment, the lighting module further includes a light-blocking plate 5, which is disposed between the reflector 2 and the light-emitting element 3. The light-blocking plate 5 is disposed between two adjacent first light-emitting units 3011, two adjacent second light-emitting units 3021, and two adjacent first light-emitting units 3011 and second light-emitting units 3021 to ensure that the reflected light from the first reflector 201 will not enter the first light-emitting unit 3011 that is not corresponding to it, nor will it enter the second light-emitting unit 3021, and to ensure that the reflected light from the second light-emitting unit 3021 will not enter the second light-emitting unit 3021 that is not corresponding to it, nor will it enter the first light-emitting unit 3011, thereby avoiding light leakage.

[0073] As one specific implementation, the lighting module is suitable for providing a high beam pattern, where the first beam pattern is mainly used to achieve the high beam function, and the upper edge of the second beam pattern is configured to be flush with the high shoulder of the low beam pattern. For example... Figure 8 As shown, this embodiment is applied to left-hand drive vehicles. The cut-off line 6 of the low beam pattern, from left to right, consists of a left low shoulder, an inflection point, and a right high shoulder 7. The upper edge of the second beam pattern is flush with the right high shoulder 7 of the low beam pattern. Figure 9 As shown, this embodiment is applied to right-hand drive vehicles. The cut-off line 6 of the low beam pattern is, from left to right, the left high shoulder 8, the connecting section and the right low shoulder. The upper edge of the second beam pattern is flush with the left high shoulder 8 of the low beam pattern.

[0074] In some specific embodiments, when the vehicle is in motion, as shown in Figure 1:

[0075] model D1 D2 D3 D4 D5 D6 D7 D8 D9 D10 Zero 0％ 0％ 0％ 0％ 0％ 60％ 45％ 35％ 25％ 25％ Left turn limit 60％ 45％ 35％ 25％ 25％ 25％ 25％ 25％ 25％ 25％ Right turn limit 0％ 0％ 0％ 0％ 0％ 60％ 70％ 80％ 70％ 60％

[0076] Table 1. Brightness distribution at zero position, left turn limit, and right turn limit.

[0077] The percentages in Table 1 represent the brightness percentage of that pixel. The rightmost portion of the multiple second light-emitting units 102 is controlled to activate at an appropriate brightness to enhance the brightness of the near beam on the right front, such as... Figure 8 As shown in Table 1, in some specific embodiments, the second light-emitting units 102 corresponding to pixels D1-D5 are turned off, and the second light-emitting units 102 corresponding to pixels D6-D10 are lit at an appropriate brightness to enhance the brightness of the right front of the low beam. When the vehicle turns left, the leftmost second light-emitting units 102 are lit one by one from right to left as needed, such as... Figure 8 As shown in Table 1, in some specific embodiments, when the vehicle is traveling straight, the second light-emitting units 102 corresponding to pixels D1-D5 are turned off, and the second light-emitting units 102 corresponding to pixels D6-D10 are lit at an appropriate brightness. When the vehicle turns left, the second light-emitting units 102 corresponding to pixels D5-D1 are gradually lit to move the inflection point of the low beam cutoff line to the left, increasing the brightness of the road surface to the left front. When turning right, as shown in Table 1, the brightness of the second light-emitting unit 102 on the right is increased as needed to enhance the brightness of the road surface to the right front. Thus, dynamic steering can be achieved. Steering is a function of automotive headlights that continuously adjusts the headlights dynamically according to the steering wheel angle, vehicle deflection rate, and driving speed. This function can provide the driver with a wider range of illumination in the corresponding direction when the vehicle is turning, significantly enhancing the safety of driving in the dark. The above solution can enhance the brightness of the low beam to the right front when driving straight and increase the illumination brightness to the left (or right) of the cutoff line when driving on a curve. This solution achieves the steering function by controlling the current of the light-emitting units, and has the advantages of reliable operation, rapid response, and low cost.

[0078] In a preferred embodiment, the first light-emitting unit 101 and the second light-emitting unit 102 are controlled separately to control the on / off state of the pixel light pattern corresponding to the light-emitting unit, so that the lighting module can provide an adaptive high beam light pattern.

[0079] In a preferred embodiment, a number of pixel patterns of the first light pattern are arranged in a one-to-one correspondence with a number of pixel patterns of the second light pattern, thereby facilitating the correspondence and control of individual pixel patterns and projection positions.

[0080] As a preferred implementation method, such as Figure 11As shown, the first reflectors 201 and the second reflectors 202 are integrally molded. Compared with the existing silicone needle-type condensers, the first reflectors 201 and the second reflectors 202 of this application can be made of PC (polycarbonate) and PMMA (polymethyl methacrylate) materials, which is cheaper. Moreover, this application does not require silicone brackets, has fewer parts, more reliable structure, shorter tolerance chain, and lower installation cost.

[0081] As a preferred method of fact-finding, such as Figure 12 As shown, the lighting module of this application also includes a circuit board, on which a plurality of first light-emitting units 101 and a plurality of second light-emitting units 102 are mounted together. By setting the light-emitting element 3, the first reflector 201 and the second reflector 203, this application enables the first light-emitting units 101 and the second light-emitting units 102 to be set on the same board, avoiding the complex structure caused by separate boards when arranging light sources vertically in the prior art.

[0082] Based on the lighting module mentioned in the above technical solution of the present invention, the present invention provides a vehicle lamp with a narrower opening in the lighting module, which is beneficial to the design of the vehicle lamp.

[0083] Based on the vehicle headlights provided by the above-mentioned technical solutions of the present invention, the present invention provides a vehicle in which the opening of the headlight lighting module is narrow, which is beneficial to the headlight design.

[0084] As can be seen from the above description, the advantages of the present invention are as follows: First, the lens opening of the lighting module of the present application is relatively narrow, which is beneficial to the design of the vehicle headlight; Second, the primary optical element of the present application uses a reflector, which can be made of PC and PMMA materials, resulting in lower cost, no need for silicone brackets, fewer parts, more reliable structure, shorter tolerance chain, and lower installation cost; Third, the first light-emitting unit and the second light-emitting unit are set on the same board, avoiding the complex structure caused by separate boards for the light source.

[0085] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0086] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately.
