Description

Technical Field

[0001] The present application relates to the technical field of vehicle lamps, and in particular to a low-beam light output module, a high- and low-beam lighting device, and a vehicle lamp. Background Art

[0002] With the development of society and the economy, the automotive industry has also grown accordingly. As automotive lighting technology continues to advance, more requirements have been placed on the functionality of headlights. In lighting devices that achieve these functions, dual-beam modules are typically installed to achieve both high and low beam patterns, thereby achieving better lighting effects.

[0003] Existing dual-beam modules all use a single, large lens (light-emitting element) to achieve both high and low beams. However, to meet specific requirements for light shape and light efficiency, modifications to this shared lens are necessary. In actual design, this often has ripple effects across the entire system. For example, to meet low beam requirements, modifications to the shared lens would require corresponding adjustments to the high beam element, often leading to a lengthy development cycle. Furthermore, optical design using a single, large lens makes it difficult to simultaneously meet the diverse requirements of multiple lighting functions.

[0004] Chinese invention patent application CN113958921A discloses a lighting module, a lighting device and a vehicle. The lighting module disclosed in the Chinese invention patent application includes only one optical lens. The optical lens adopts a single optical lens, and the light input part includes multiple light input surfaces, but all the light input surfaces share one light output surface. In essence, it is still a single large lens structure.

[0005] Taiwan invention patent TW202232024A (TWI793524B) discloses a vehicle lamp device, which includes: a light-emitting unit, which includes at least one first light-emitting element and at least one second light-emitting element, at least one of the second light-emitting elements is adjacent to the at least one first light-emitting element; a first reflective unit, which corresponds to the at least one first light-emitting element; a second reflective unit, which corresponds to the at least one second light-emitting element; and a lens module, which has a light incident surface and a light emitting surface, the light incident surface facing the light-emitting unit, the first reflective unit, and the second reflective unit; wherein, the first light beam generated by the at least one first light-emitting element is projected onto a first portion of the light incident surface by the first reflective unit; wherein, the second light beam generated by the at least one second light-emitting element is projected onto a second portion of the light incident surface by the second reflective unit. This Taiwan invention patent TW202232024A uses dual reflection units (the first reflection unit controls the low beam and the second reflection unit controls the high beam) to direct light to different areas of the light incident surface of the same lens module, but still relies on a single shared lens.

[0006] Taiwan invention patent TW202233990A (TWI788114B) discloses a vehicle lamp device, which includes a light-emitting unit, which includes at least one first light-emitting element and at least one second light-emitting element, the at least one second light-emitting element being adjacent to the at least one first light-emitting element; a first optical unit, which corresponds to the at least one first light-emitting element; and a lens module, which has a light-incident surface and a light-outcending surface, the light-incident surface facing the light-emitting unit and the first optical unit; wherein the first light beam generated by the at least one first light-emitting element is projected onto a first portion of the light-incident surface by the first optical unit; wherein the at least one first light-emitting element has a first light-emitting surface, and the at least one second light-emitting element has a second light-emitting surface, and the first light-emitting surface and the second light-emitting surface directly face the light-incident surface. Taiwan's invention patent TW202233990A utilizes a "light-emitting surface directly incident on the light-entering surface" + "optical unit reflection and light control" design to precisely control the position of the light-cutoff line, meeting regulatory requirements and eliminating the need for a reflector cup, improving assembly efficiency. However, in this patent, all light ultimately enters the light-entering surface of the same lens module, failing to implement a unitized design within each module.

[0007] Taiwan Utility Model Patent TWM611948U discloses a vehicle lamp device comprising: a light-emitting unit comprising at least one first light-emitting element and at least one second light-emitting element, the at least one second light-emitting element being adjacent to the at least one first light-emitting element; a first reflector corresponding to the at least one first light-emitting element; a second reflector corresponding to the at least one second light-emitting element; and a lens module having a light-incident surface and a light-exiting surface, the light-incident surface facing the light-emitting unit, the first reflector, and the second reflector. A first light beam generated by the at least one first light-emitting element is projected onto a first portion of the light-incident surface by the first reflector, while a second light beam generated by the at least one second light-emitting element is projected onto a second portion of the light-incident surface by the second reflector. This utility model addresses the core issue of conventional vehicle lamps with a narrow light beam range by utilizing dual reflectors for coordinated light control (the first reflector reflects the low beam in a directionally directed manner, while the second reflector reflects the high beam in a directionally directed manner). The light shape can be flexibly controlled by adjusting the spacing (adjusting the spacing between the third notch of the second reflective unit and the light source (H1-H3)), but the light still converges to the same lens module, and the unitized design within each module is not realized.

[0008] Chinese utility model patent CN215372307U discloses a lighting module, lighting device, and vehicle. The lighting module includes a light source, a reflective element, and an optical lens. The reflective element is arranged to reflect light emitted by the light source and allow it to enter the optical lens. The optical lens includes a light input portion with horizontal unidirectional collimation and a light output portion with vertical unidirectional collimation. The light input portion includes at least two light input surfaces. The reflective element includes reflectors connected in sequence and corresponding to the light input surfaces. The reflectors are parabolic reflectors or quasi-parabolic reflectors. Chinese utility model patent CN215372307U uses a parabolic reflector array in conjunction with the optical lens, but all reflectors share multiple light input surfaces of the same lens, essentially integrating multiple light sources into a single lens.

[0009] Korean invention patent application KR1020220032243A discloses a vehicle lamp comprising a first light-emitting unit for generating light to form a first beam pattern; and a light-emitting unit for generating light to form a second beam pattern, the second beam pattern being arranged perpendicularly to the first light-emitting unit and also perpendicular to the first beam pattern. The transmitting unit comprises the first light-emitting unit and an optical unit for transmitting light generated by at least one second light-emitting unit. The shielding portion comprises a first shield and a second shield, the first shield blocking a portion of the light generated by the first light-emitting unit, and a second shield positioned to one side of the first shield blocking a portion of the light generated by the second light-emitting unit. Furthermore, the first and second shields are positioned at different vertical positions in the vehicle lamp. Korean invention patent application KR1020220032243A utilizes two vertically arranged light-emitting units and two shields for zoned light control, but all light is emitted through a shared optical system.

[0010] Chinese utility model patent CN217816527U discloses a lens optical module comprising: a light source, at least one reflector, and an optical lens assembly; the reflector is arranged to reflect light emitted by the light source and direct it into the optical lens assembly; the optical lens assembly comprises an inner lens and an outer lens arranged in sequence along the optical axis; the outer lens has a linear focus along the horizontal direction, and the inner lenses each have an arc focus along the vertical direction; the focal length of the outer lens is greater than that of the inner lens. This Chinese utility model patent CN217816527U achieves high light efficiency and a wide light pattern through a separate design of "vertical light control by the inner lens + horizontal light control by the outer lens," while still maintaining a single optical system.

[0011] Chinese invention patent CN112513522B discloses a lighting module for a motor vehicle, comprising: a light source capable of emitting light; a light collector having a reflective surface configured to collect the light emitted by the light source and reflect the light into a light beam along the optical axis of the module; and an optical system configured to project the light beam; the optical system configured to form an image of the reflective surface of the light collector, the optical system having a focal point located on the optical axis and located between the light source and a rear edge of the reflective surface along the optical axis relative to the overall propagation direction of the light beam. Chinese invention patent CN112513522B replaces a traditional sunshade with a physical edge of the reflective surface of the light collector, achieving "what you see is what you get" light shape control, but relies on a single optical system to project the light beam.

[0012] Chinese utility model patent CN212618084U discloses an optical lens comprising a light input portion and a light output portion. The light input portion is formed with a first unidirectional alignment surface, and the light output portion is formed with a second unidirectional alignment surface. The alignment orientation of the first unidirectional alignment surface and the alignment orientation of the second unidirectional alignment surface are perpendicular to each other, and the first unidirectional alignment surface and the second unidirectional alignment surface together form the focal point or focusing area of the optical lens. This Chinese utility model patent CN212618084U improves the traditional optical path by using a "hyperbolic orthogonal lens" to achieve an asymmetric light shape, but with a single lens structure.

[0013] Chinese utility model patent CN211694711U discloses a vehicle lighting optical element comprising multiple primary optical units and a secondary optical unit. The primary and secondary optical units are capable of receiving light and sequentially projecting it through the primary and secondary optical units into an illumination light pattern. The secondary optical units comprise secondary light entrances and secondary light exits, each light entrance having a secondary light entrance surface corresponding to each primary optical unit. The secondary light exit surfaces are smoothly curved, and the multiple primary optical units are arranged along the length of the secondary light exit surfaces. To address gap and volume issues associated with multi-module splicing, CN211694711U integrates the optical paths of multiple primary optical units using secondary curved surfaces, but all units share the same light exit surface.

DETAILED DESCRIPTION

[0039] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. It should be noted that, in the absence of conflict, the various features in the embodiments of the present application can be combined with each other, and the combined embodiments are still within the scope of protection of the present application.

[0040] In the description of this application, the terms "first," "second," "third," etc. are used only to distinguish descriptions and should not be understood to indicate or imply relative importance. The terms "perpendicular" and "parallel" do not mean absolutely perpendicular or parallel, but can mean approximately perpendicular or approximately parallel.

[0041] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0042] It should be understood that, in order to facilitate the description of this application and simplify the description, the terms "front and rear" refer to the front and rear direction y of the lighting device along the light-emitting direction, the terms "left and right" refer to the left and right direction x of the lighting device itself, and the terms "up and down" refer to the up and down directions z of the lighting device itself, which are usually roughly the same as the front, back, left, right, up and down directions of the vehicle; the terms are based on the orientation or position relationship shown in the accompanying drawings, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application; moreover, the orientation terms for the lighting device of this application should be understood in combination with the actual installation status.

[0043] In this application, the "beam pattern" refers to the shape of the headlights projected onto a light distribution screen 25 meters in front of the vehicle. The "cutoff line" refers to the line where the light projected onto the light distribution screen significantly changes in brightness. The primary low-beam pattern is the central area of the low-beam pattern, with high illumination. The auxiliary low-beam pattern is the extended area of the low-beam pattern, ensuring that the left and right illumination ranges meet the requirements.

[0044] In one aspect of the embodiment of the present application, Figure 1 or Figure 2 As shown, a light output module 100 is provided, comprising a plurality of light sources 101 and a plurality of optical units 110, wherein the light sources 101 are located on the light incident side of the optical units 110, so that the optical units 110 can modulate the light emitted by the light sources 101. Figure 1 As shown, a plurality of optical units 110 are arranged in a horizontal direction, as shown in FIG. Figure 2 As shown, a plurality of optical units 110 are arranged vertically.

[0045] like Figure 1 or Figure 2 As shown, each optical unit 110 includes a reflecting part 120 and a lens unit. The light source 101 corresponds to the reflecting part 120. The lens unit is located on the light-emitting side of the reflecting part 120, and the focus of the lens unit is set on the reflecting surface of the reflecting part 120 or near the reflecting surface to ensure clear imaging. Therefore, after the light source 101 emits light, the light is reflected by the reflecting surface of the reflecting part 120 and then enters the lens unit. After being modulated by the lens unit, it is finally emitted to form a light-shaping unit.

[0046] Therefore, the multiple optical units 110 of the light output module 100 can form multiple light-shaping units, and the multiple light-shaping units are combined to form the light output shape of the light output module 100 .

[0047] by Figure 1 Take the light-emitting module 100 shown as an example: the light-emitting module 100 includes four optical units 110 arranged horizontally (along the x direction), each optical unit 110 has a reflective portion 120 and a lens unit, and each optical unit 110 cooperates with the light source 101 to form a light-shaped unit. Finally, the four light-shaped units are combined horizontally to form the light-emitting shape of the light-emitting module 100.

[0048] by Figure 2 Take the light-emitting module 100 shown as an example: the light-emitting module 100 includes two optical units 110 arranged vertically (along the z direction), each optical unit 110 has a reflective portion 120 and a lens unit, and each optical unit 110 cooperates with the light source 101 to form a light-shaped unit. Finally, the two light-shaped units are combined to form the light-emitting light shape of the light-emitting module 100.

[0049] In summary, the light output module 100 is unitized (multiple light sources 101 and multiple optical units 110), thereby making the optical units 110 in the light output module 100 relatively independent, and their respective light shape modulations are more flexible, so that when making local adjustments to the light output shape, only some of the optical units 110 can be adjusted, and the remaining optical units 110 can be avoided from being adjusted. Compared with directly setting a single large lens in the light output module 100, the present application is conducive to shortening the research and development cycle, and can achieve more refined light shape adjustment, thereby improving the accuracy of achieving the ideal light shape.

[0050] It can be understood that in the light output module 100 of the present application, multiple light sources 101 and multiple optical units 110 can correspond one to one or not one to one, as long as each optical unit 110 can receive the light emitted by the light source 101 and modulate it accordingly to form a light-shaped unit.

[0051] In addition, multiple optical units 110 can be arranged horizontally or vertically, and can be roughly horizontally or vertically, and does not refer to absolute horizontal and absolute vertical. When arranged specifically, they can be adjusted according to the extension direction of the light-emitting surface of the lighting device using the light-emitting module 100 (for example, a flat surface, a curved surface, etc.) and the light distribution requirements.

[0052] Furthermore, when the focus of the lens unit is located on or near the reflecting surface of the reflecting portion 120, including but not limited to the focus being located at the boundary, near the boundary, and non-boundary of the reflecting surface, for example, when the focus is located at or near the boundary of the reflecting surface, the light output module 100 can be applied to a low-beam lighting device; when the focus is located on or near the reflecting surface (except at or near the boundary of the reflecting surface), the light output module 100 can be applied to a high-beam lighting device.

[0053] Optionally, the lens unit includes a lens 130, which can firstly contribute to the miniaturization of the lens unit and at the same time, can also prevent more light from being refracted to the outside, thereby reducing light loss. Figures 1 to 2 As shown, the cross-section of the light incident surface of the lens 130 (along the x-direction) and the longitudinal section of the light emitting surface (along the z-direction) are both curves. Thus, after the light enters the lens 130 through the reflecting surface, bidirectional collimation can be achieved by the light incident surface and the light emitting surface of the lens 130, thereby obtaining a better light shaping effect in the light emitting direction (along the y-direction). Of course, in another embodiment, when the lens unit includes one lens 130, one of the cross-section and the longitudinal section of the light incident surface of the lens 130 is a curve, and the other is a straight line. Thus, after the light enters the lens 130 through the reflecting surface, unidirectional collimation can be achieved by the light incident surface of the lens 130, and the collimation direction can be horizontal or vertical. It is not excluded that in another embodiment, the cross-section and the longitudinal section of the light incident surface of the lens are both curves.

[0054] Optionally, the lenses 130 of two adjacent lens units can be spliced together to form a module lens 141, for example Figure 1 The lenses 130 arranged laterally are sequentially spliced in the transverse direction to form a module lens 141, for example Figure 2 The lenses 130 arranged vertically are sequentially spliced vertically to form a module lens 141 .

[0055] Optionally, the lens unit may also include multiple lenses, thereby enabling the light to be modulated multiple times, which helps to obtain a better light shape. Figure 3 As shown, the optical unit 110 is arranged horizontally (along the x-direction), and the lens unit may further include an inner lens 150 and an outer lens 160, wherein the outer lens 160 is arranged on the light-emitting side of the reflective portion 120, and the inner lens 150 is located between the reflective portion 120 and the outer lens 160. As a result, after passing through the reflective portion 120, the light first enters the inner lens 150, and then exits from the inner lens 150 to the outer lens 160 and finally exits to form a light-shaping unit. It should be understood that in other embodiments, when the optical unit 110 is arranged vertically (along the z-direction), the lens unit may still include the inner lens 150 and the outer lens 160. The arrangement thereof differs from the embodiment of the horizontal arrangement only in the arrangement direction. Therefore, the arrangement and understanding can be referred to and will not be repeated.

[0056] The inner lens 150 in the lens unit is along the optical axis direction (ie Figure 3 The front and rear position (in the y direction) can be determined according to the focal length of the inner lens 150. In addition, when the focal length of the inner lens 150 becomes larger, the brightness of the light shape will increase, but the size of the light shape will decrease. The focal length can be flexibly adjusted according to the light shape and customer needs.

[0057] When the lens unit realizes the collimation function, the light incident on the inner lens 150 can collimate the light emitted from the reflective portion 120 along a first direction, and the light emitting surface of the outer lens 160 can collimate the light emitted from the reflective portion 120 along a second direction, wherein the first direction and the second direction are perpendicular. Thus, bidirectional collimation can be realized by combining the inner lens 150 and the outer lens 160. In a specific implementation, as Figure 3 As shown, the first direction may be the x-direction, the second direction may be the z-direction, the cross-section of the light incident surface of the inner lens 150 along the x-direction may be a curve, and the longitudinal section along the z-direction may be a straight line, and the longitudinal section of the light exit surface of the outer lens 160 along the z-direction may be a curve, and the cross-section along the x-direction may be a straight line.

[0058] Optionally, adjacent inner lenses 150 in a plurality of optical units 110 may be spliced together to form a module inner lens 142, and adjacent outer lenses 160 in a plurality of optical units 110 may be spliced together to form a module outer lens 143. Figure 3 As shown, the four inner lenses 150 are sequentially spliced in the transverse direction to form the module inner lens 142 , and the four outer lenses 160 are spliced in the transverse direction to form the module outer lens 143 .

[0059] Optionally, the light-emitting surfaces of multiple lens units are connected to form a smooth light-emitting surface of the light-emitting module 100. Figure 2 As shown, when the lens unit includes a lens 130, the light-emitting surface of the module lens 141 formed along the vertical arrangement can be a smooth curved surface. Of course, in other embodiments, the light-emitting surface of the module lens 141 can also be a smooth flat surface. Figure 3 As shown, the light emitting surface of the lens 142 inside the module can be a smooth plane, and the light incident surface and the light emitting surface of the lens 143 outside the module can be smooth curved surfaces.

[0060] It should be understood that when the light incident surface and / or light emitting surface of the spliced module outer lens 143 is a smooth curved surface or a flat surface, and the module outer lens 143 is integrally formed, there may not be obvious boundary lines between the units in the actual product, for example Figure 3 In the embodiment, the light incident surface of the outer lens 143 of the module is a smooth curved surface, and in the actual product, there may not be a clear boundary line between the units. Figure 3The dotted line on the light incident surface of the lens 143 outside the module is only a virtual line for easier understanding of the unit division and may not be set in the actual product. Correspondingly, the light incident surface and light emitting surface of the lens 142 inside the module are similar.

[0061] Optional, such as Figures 1 to 3 As shown, the reflecting surface of the reflecting portion 120 can be any one of a parabola, a quasi-parabola, an ellipsoid and a quasi-ellipsoid. The quasi-parabola refers to a curved surface that is similar to a parabola, and the quasi-ellipsoid refers to a curved surface that is similar to an ellipsoid. Regardless of the type of curved surface, as long as the reflecting surface can emit the light emitted by the light source 101 roughly parallel to the lens unit, it will help to improve the utilization rate of light and improve the lighting brightness.

[0062] The light output module 100 provided in the present application can be used in a lighting device. The light output module 100 can be used as any module in the lighting device, such as high beam, low beam, auxiliary high beam, corner light, fog light, etc. When the lighting device includes multiple light output modules 100, it can realize multiple lighting functions such as low beam and high beam, low beam and ADB high beam, main low beam and auxiliary low beam, etc. According to different lighting functions, the lighting device can be divided into a low beam lighting device, a high beam lighting device, a high and low beam integrated lighting device, etc., and the present application does not impose any specific restrictions on it.

[0063] By applying the aforementioned light-emitting module 100, the unitized characteristics of the light-emitting module 100 can be utilized to make the light shape modulation of each light-emitting module 100 in the lighting device more flexible, which is conducive to shortening the research and development cycle, and can achieve refined light shape adjustment within the light-emitting module 100, thereby improving the accuracy of achieving the ideal light shape. On this basis, when the lighting device includes multiple light-emitting modules 100, each light-emitting module 100 can also be made independent of each other, that is, during design, the optical unit 110 in each light-emitting module 100 only needs to consider the light emission requirements of its own module, and the light shape modulation of each light-emitting module 100 is more flexible and does not interfere with each other, avoiding the need to design a single large lens that simultaneously meets the light emission requirements of multiple light-emitting modules 100. When adjusting the light shape of some modules in the multiple light-emitting modules 100, only the light-emitting modules 100 that need to be adjusted need to be adjusted, which is conducive to shortening the research and development cycle.

[0064] In addition, since the two adjacent light-emitting modules 100 are independent of each other, there is no problem of sharing. Therefore, it is possible to avoid setting up a device that divides the light shape between the two, such as a shading structure. While saving costs, the connectivity of the two light-emitting light shapes corresponding to the two adjacent light-emitting modules 100 can be improved through flexible adjustment, avoiding the appearance of dark areas between the two adjacent light-emitting light shapes or excessive brightness at the connection.

[0065] For the convenience of description, the low beam lighting device, the high beam lighting device and the high and low beam integrated lighting device will be schematically described below with reference to the accompanying drawings.

[0066] Another aspect of the embodiment of the present application is as follows Figure 1 、 Figure 3 or Figure 4 As shown, a low-beam lighting device is provided, comprising at least one light-emitting module 100 as described above, wherein the focus of the lens unit is arranged at or near the boundary of the reflecting surface of the reflecting portion 120 close to the light source 101. Thus, the boundary of the reflecting surface or the vicinity of the boundary can be conveniently utilized as a cut-off line structure 121, so that the light-emitting module 100 emits a low-beam light shape having a bright and dark cut-off line.

[0067] Optional, such as Figure 1 As shown, the low beam lighting device includes a light output module 100, which has a plurality of optical units 110 arranged laterally. Each optical unit 110 includes a reflective portion 120 and a lens unit, and the lens unit includes a lens 130. Thus, the light reflected by the reflective portion 120 is formed into a plurality of light-shaped units through the plurality of lens units. The plurality of light-shaped units can be combined to form a low beam light shape.

[0068] Optional, such as Figure 3 As shown, the low-beam lighting device includes a light output module 100, which has a plurality of optical units 110 arranged laterally. Each optical unit 110 includes a reflective portion 120 and a lens unit. The lens unit includes an inner lens 150 and an outer lens 160. Thus, the light reflected by the reflective portion 120 is formed into a plurality of light-shaped units through the plurality of lens units. The plurality of light-shaped units can be combined to form a low-beam light shape.

[0069] Optional, such as Figures 1 to 4 As shown, the reflective portion 120 corresponds to the lens unit one by one. Of course, in other embodiments, multiple reflective portions 120 may correspond to one lens unit, for example, Figure 8 The multiple reflective parts 120 in the high-beam light output module 320 are arranged corresponding to one lens unit.

[0070] Optionally, the low-beam lighting device may further include a plurality of light emitting modules 100 , whereby the light emitting patterns formed by the plurality of light emitting modules 100 are superimposed to serve as the low-beam light pattern of the low-beam lighting device.

[0071] For example Figure 4As shown, the low beam lighting device includes two light emitting modules 100, namely a main low beam module 220 and an auxiliary low beam module 210. For ease of understanding, the low beam lighting device is divided into the main low beam module 220 and the auxiliary low beam module 210 by a dotted line. The main low beam module 220 can emit a main low beam light shape, and the auxiliary low beam module 210 can emit an auxiliary low beam light shape. Specifically: Figure 4 In the example, the main low beam module 220 includes multiple light sources 101 and multiple optical units 110. The multiple optical units 110 include a reflector 120 and a lens unit. The lens unit includes an inner lens 150 collimated along the x-direction and an outer lens 160 collimated along the z-direction. The multiple inner lenses 150 are spliced to form a module inner lens 142. The multiple outer lenses 160 are spliced to form a module outer lens 143. Figure 5 As shown, for the main low beam module 220: the light source 101 emits light along the y direction after passing through multiple optical units 110 to form multiple light shape units, and the multiple light shape units are combined to form a main low beam light shape with a bright and dark cut-off line.

[0072] Figure 4 In the figure, the auxiliary low beam module 210 includes multiple light sources 101 and multiple optical units 110. The multiple optical units 110 include a reflector 120 and a lens unit. The lens unit includes an inner lens 150 collimated along the x-direction and an outer lens 160 collimated along the z-direction. The multiple inner lenses 150 are spliced to form a module inner lens 142. The multiple outer lenses 160 are spliced to form a module outer lens 143. Figure 6 As shown, for the auxiliary low beam module 210: the light source 101 emits light along the y direction after passing through multiple optical units 110 to form multiple light shape units, and the multiple light shape units are combined to form an auxiliary low beam light shape with a bright and dark cut-off line.

[0073] By Figure 5 The main low beam pattern shown and Figure 6 The auxiliary low beam light shapes shown are superimposed to obtain the low beam light shape of the low beam lighting device. The main low beam light shape can improve the central brightness of the low beam light shape, and the auxiliary low beam light shape can better widen the low beam light shape.

[0074] Of course, the multiple light output modules 100 can be arranged horizontally or vertically. This application does not impose any special restrictions on this and can be reasonably arranged according to needs.

[0075] Optionally, the plurality of optical units 110 are arranged horizontally, and the arrangement direction of the light output module 100 is parallel to the arrangement direction of the optical units 110. Figure 4As shown, the optical units 110 in the main low beam module 220 and the auxiliary low beam module 210 are arranged in the transverse direction (along the x-direction), and the main low beam module 220 and the auxiliary low beam module 210 are also arranged in the transverse direction (along the x-direction).

[0076] Optionally, the plurality of optical units 110 are arranged horizontally, and the arrangement direction of the light output module 100 is perpendicular to the arrangement direction of the optical units 110. For example, the optical units 110 in the main low beam module 220 and the auxiliary low beam module 210 are both arranged horizontally, and the main low beam module 220 and the auxiliary low beam module 210 can also be arranged vertically.

[0077] Optionally, two adjacent light output modules 100 in the plurality of light output modules 100 may not be spliced together, that is, there may be a certain distance between them, for example Figure 4 As shown, there is a gap between the main low beam module 220 and the auxiliary low beam module 210 .

[0078] Optionally, the light emitting surfaces of two adjacent light emitting modules 100 in the plurality of light emitting modules 100 are connected to form a smooth curved surface or a flat surface, for example, Figure 4 There is no gap between the main low beam module 220 and the auxiliary low beam module 210, so that the light emitting surfaces of the module outer lens 143 or the module lens 141 in the main low beam module 220 and the auxiliary low beam module 210 are connected, thereby forming a smooth curved surface or a flat surface.

[0079] In another aspect of the present application, a high-beam lighting device is provided, comprising at least one light output module 100 as described above. The focal point of the lens unit can be set on or near the reflective surface (except at or near the boundary of the reflective surface), thereby avoiding obstruction of the formed high-beam light pattern.

[0080] The high beam lighting device includes a light emitting module 100, such as Figure 7 In the figure, the light output module 100 is located below the dotted line and serves as a high beam light output module 320. The high beam module has a plurality of optical units 110 arranged laterally. Each optical unit 110 includes a reflecting portion 120 and a lens unit. The lens unit includes a lens 130. Thus, the light reflected by the reflecting portion 120 forms a plurality of light-shaped units through the lens unit. The plurality of light-shaped units can be combined to form a high beam light shape.

[0081] The high beam lighting device includes a light emitting module 100, such as Figure 9In the figure, the light output module 100 is located below the dotted line and serves as a high beam light output module 320. The high beam module has multiple optical units 110 arranged laterally. Each optical unit 110 includes a reflecting portion 120 and a lens unit. The lens unit includes a high beam inner lens 191 and a high beam outer lens 192. Thus, the light reflected by the reflecting portion 120 forms multiple light-shaped units through the lens unit, and the multiple light-shaped units can form a high beam light shape after being combined.

[0082] Of course, in other embodiments, the high-beam lighting device may further include two or more light output modules 100. When two or more light output modules 100 are arranged, they may also be arranged horizontally or vertically.

[0083] Optional, such as Figure 7 or Figure 9 As shown, the reflective surface of the high beam module corresponds to the lens unit one by one. Of course, in other embodiments, for example Figure 8 In the figure, the multiple reflective surfaces in the high beam light output module 320 correspond to one lens unit, which is used for ADB high beam lighting.

[0084] Optionally, two adjacent light output modules 100 among the multiple light output modules 100 in the high-beam lighting device may not be spliced together, that is, there may be a certain distance between them.

[0085] Optionally, the light emitting surfaces of two adjacent light emitting modules 100 among the multiple light emitting modules 100 in the high-beam lighting device are connected to form a smooth curved surface or a flat surface.

[0086] Another aspect of the present application provides a high and low beam integrated lighting device, such as Figures 7 to 11 As shown, the high and low beam integrated lighting device includes the two aforementioned light emitting modules 100 , one of which is a low beam light emitting module 310 capable of forming a low beam light shape, and the other light emitting module 100 is a high beam light emitting module 320 capable of forming a high beam light shape.

[0087] For example Figures 7 to 11 As shown, the high and low beam integrated lighting device is divided into a low beam light emitting module 310 and a high beam light emitting module 320 by a dotted line.

[0088] Optionally, the lens unit of at least one of the low beam light output module 310 and the high beam light output module 320 includes a lens 130. For example Figure 7As shown, the low beam light output module 310 includes multiple light sources 101 and multiple optical units 110. The multiple optical units 110 include a reflector 120 and a lens unit. The lens unit includes a bidirectional collimating lens 130. The multiple lenses 130 are spliced to form a module lens 141. Therefore, for the low beam light output module 310: the light source 101 is emitted along the y direction after passing through the multiple optical units 110 to form multiple light-shaped units. The multiple light-shaped units are combined to form a low beam light shape with a bright and dark cut-off line. Figure 7 As shown, the high beam emission module 320 includes multiple light sources 101 and multiple optical units 110, the multiple optical units 110 include a reflective part 120 and a lens unit, the lens unit includes a bidirectional collimating lens 130, and the multiple lenses 130 are spliced to form a module lens 141. Therefore, for the high beam emission module 320: the light source 101 is emitted along the y direction after passing through the multiple optical units 110 to form multiple light-shaped units, and the multiple light-shaped units are combined to form the high beam light shape.

[0089] Optionally, the lens unit of one of the low beam light emitting module 310 and the high beam light emitting module 320 includes a lens 130, and the lens unit of the other includes an inner lens 150 and an outer lens 160 sequentially arranged on the light emitting side of the reflector 120. Figure 8 As shown, the low beam light output module 310 includes multiple light sources 101 and multiple optical units 110. The multiple optical units 110 include a reflector 120 and a lens unit. The lens unit includes an inner lens 150 collimated along the x direction and an outer lens 160 collimated along the z direction. The multiple inner lenses 150 are spliced to form a module inner lens 142, and the multiple outer lenses 160 are spliced to form a module outer lens 143. Therefore, for the low beam light output module 310: the light source 101 is emitted along the y direction after passing through the multiple optical units 110 to form multiple light shape units. The multiple light shape units are combined to form a low beam light shape with a bright and dark cut-off line. Figure 8 As shown, the high-beam light output module 320 includes multiple light sources 101 and multiple optical units 110. The multiple optical units 110 include reflectors 120 and lens units. The lens units include lenses 130 that are bidirectionally collimated along the x-direction and the z-direction. The multiple lenses 130 are spliced together to form a module lens 141. Thus, for the high-beam light output module 320: the light source 101, after passing through the multiple optical units 110, is emitted along the y-direction to form multiple light-shaping units, which are combined to form the high-beam light pattern.

[0090] Optional, such as Figure 9As shown, the lens unit of the low beam output module 310 includes a low beam inner lens 181 and a low beam outer lens 182 which are sequentially arranged on the light output side of the reflective portion 120; the lens unit of the high beam output module 320 includes a high beam inner lens 191 and a high beam outer lens 192 which are sequentially arranged on the light output side of the reflective portion 120; adjacent low beam inner lenses 181 are spliced to form the low beam inner lens 181, and adjacent low beam outer lenses 182 are spliced to form the low beam module outer lens 143; adjacent high beam inner lenses 191 are spliced to form the high beam inner lens 191, and adjacent high beam outer lenses 192 are spliced to form the high beam module outer lens 143.

[0091] Optional, such as Figures 7 to 11 As shown, the low-beam light-emitting module 310 and the high-beam light-emitting module 320 are arranged in the longitudinal direction (along the z direction).

[0092] Optionally, the low beam inner lens 181 and the high beam inner lens 191 are arranged front to back along the front-to-back direction (along the y direction), for example Figure 10 As shown, the low-beam inner lens 181 is positioned rearward, while the high-beam inner lens 191 is positioned forward. This can be determined based on their respective focal lengths. It should be understood that increasing the focal length increases brightness but reduces the size of the light pattern. Therefore, a reasonable focal length setting can be made based on the light pattern and customer needs. Of course, in another embodiment, the low-beam inner lens 181 and the high-beam inner lens 191 are arranged longitudinally (along the z-direction) and integrally formed, i.e., the low-beam inner lens 181 and the high-beam inner lens 191 are spliced longitudinally.

[0093] Optionally, in order to dissipate heat for the light source 101, a heat sink 330 may be provided between the light sources 101 of two adjacent light output modules 100. By utilizing the opposite sides of the heat sink 330, the light sources 101 of the two light output modules 100 can be cooled separately. Thus, the space between the light sources 101 of the two light output modules 100 can be fully utilized to reduce the volume. Figure 11 As shown, a heat sink 330 can be provided between the light sources 101 of the low-beam light emitting module 310 and the high-beam light emitting module 320 , and the light sources 101 of the two light emitting modules 100 can be cooled separately by utilizing the opposite sides of the heat sink 330 .

[0094] Optionally, in order to improve the heat dissipation capability of the light source 101, a corresponding heat sink 330 may be provided for each light source 101 of the light output module 100, for example Figure 21 As shown, a radiator 330 for dissipating heat for the light source 101 of the low beam emitting module 310 is provided on the side of the low beam emitting module 310 away from the high beam emitting module 320. Similarly, a radiator 330 for dissipating heat for the light source 101 of the high beam emitting module 320 is provided on the side of the high beam emitting module 320 away from the low beam emitting module 310.

[0095] Optional, such as Figure 12 As shown, for the low beam light output module 310, there are 4 light sources 101 and 4 optical units 110. Figure 12 The four dotted boxes shown in the figure are for reference only, and are respectively the first unit 111, the second unit 112, the third unit 113 and the fourth unit 114 arranged along the x-direction, and the light emitting direction is the y-direction, wherein the first unit 111 and the second unit 112 are respectively two units close to the edge, and the third unit 113 and the fourth unit 114 are respectively two units close to the middle.

[0096] In order to obtain a better low beam shape, the inner lenses 150 of different optical units 110 in the low beam output module 310 may be configured differently, for example Figure 12 In the embodiment, the cross-sectional curvature of the light incident surface of the inner lens 150 of the first unit 111 and the second unit 112 near the edge is greater than the cross-sectional curvature of the light incident surface of the inner lens 150 near the third unit 113 and the fourth unit 114 in the middle. Figure 13 As shown, when the light reflected by the reflective surface enters the low beam inner lens 181, part of the light entering the first unit 111 and the second unit 112 can be refracted at a larger angle, thereby expanding the irradiated area and obtaining the light corresponding to the first unit 111. Figure 15 The right half light shape shown and the corresponding second unit 112 are as shown in FIG. Figure 16 The left half of the light shape shown in FIG. 1 makes the light shape incident on the third unit 113 and the fourth unit 114 form as shown in FIG. Figure 14 The middle light shape shown in the figure is superimposed on the three to obtain the following Figure 17 As shown in the figure, the low beam light shape is better widened. Figure 13 As shown, the light incident through the light-entering surfaces with larger cross-sectional curvatures on both sides of the low-beam inner lens 181 (the inner lenses 150 of the first unit 111 and the second unit 112) will be refracted at a large angle, and at this time, these two parts of light will intersect in the transverse direction (x direction), that is, in the horizontal direction. When the module outer lens 143 is placed at a certain point in the light path during the crossing process, the module outer lens 143 does not need to be very wide to allow the light to pass through, and ultimately the left and right openings of the lens can be further reduced.

[0097] like Figure 18 or Figure 19 As shown, the surface shape 1431 of the light-emitting surfaces of the outer lenses of adjacent light-emitting modules after being connected can be a convex or concave surface, thereby improving the continuity of the appearance. Of course, according to needs, the surface shape 1431 of the light-emitting surfaces of the outer lenses of adjacent light-emitting modules after being connected can also be changed accordingly, for example Figure 20 As shown, the surface shape 1431 after the light-emitting surfaces of the outer lenses of adjacent light-emitting modules are connected can also be a plane.

[0098] Optional, such as Figure 21 As shown, the high and low beam integrated lighting device includes a reflective assembly 450 fixed with a reflective portion 120, a low beam circuit board 440 integrated with the low beam light emitting module 310 light source 101, a high beam circuit board 430 integrated with the high beam light emitting module 320 light source 101, an inner lens assembly 420 provided with a low beam inner lens 181 and a high beam inner lens 191, a lens bracket 410, a low beam outer lens 182 and a high beam outer lens 192 connected as a whole, which can be assembled along the direction of the light path.

[0099] In another aspect of the embodiments of the present application, a vehicle lamp is provided, comprising the aforementioned low-beam lighting device, the aforementioned high-beam lighting device, or the aforementioned integrated high- and low-beam lighting device. The vehicle lamp of the present application can be used in vehicles such as bicycles, motorcycles, automobiles, ships, aircraft, etc., without limitation in the present application.

[0100] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.

[0101] The above describes specific embodiments of the present invention. It should be understood that the present invention is not limited to the specific embodiments described above, and those skilled in the art may make various changes or modifications within the scope of the claims, which do not affect the essence of the present invention. The embodiments of this application and the features in the embodiments may be combined with each other in any manner unless there is a conflict.
