[0028]

[0023] The embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. In this specification, the same or similar components are designated by the same or similar reference numerals. The following description of the embodiments of the present disclosure with reference to the drawings is intended to explain the overall concept disclosed in the present disclosure and should not be construed as limiting the present disclosure.

[0029] Additionally, in the following detailed description, for ease of explanation, numerous specific details are given to provide a comprehensive understanding of the embodiments of the present disclosure. However, it will be apparent that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in diagrammatic form to simplify the drawing.

[0030] 1-14 schematically illustrate the structure of a lighting module according to an exemplary embodiment of the present disclosure. The lighting module can function as a component of a lamp device that directs light from a light source to be emitted with a desired lighting effect (e.g., a desired intensity distribution or direction) to achieve a lighting or signaling function. As an example, the lamp device may be installed as a lamp in a vehicle, including, but not limited to, a headlight, such as a dipped headlight and / or a full-beam headlight, or a lamp providing other lighting functions, such as interior lighting. It will be understood that in addition to the lighting module, the lamp device may further include other components not shown, such as a housing for accommodating the lighting module, an optional light distribution screen, a connector, and installation / positioning elements. The term "vehicle" as used herein can refer to any type of vehicle, such as an automobile, a motorcycle, or other mobile machine capable of carrying at least one passenger or used to transport people or goods.

[0031] In the illustrated embodiment, the lighting module mainly includes a light source (110; 120) and an integrated light distribution control component (210; 220). The light source (110; 120) may include any suitable light-emitting device, such as a halogen bulb, a xenon lamp, an LED, or a laser. Depending on actual needs, the lighting module may include one or more light sources (110; 120) arranged in various formats. The light source may be arranged on a conductor. As an example, the lighting module may further include a circuit board 300, such as a PCB, and the light source (110; 120) is mounted on the circuit board 300.

[0032] In order to timely and effectively dissipate heat from the lighting module (e.g., a light source or other heating component), the lighting module may further include a heat sink 400. As an example, the heat sink 400 may include a heat sink 410 for heat conduction and a plurality of heat dissipation fins 420 extending from the heat sink 410, and the circuit board 300 (110; 120) on which the light distribution control component (210; 220) and the light source are mounted may be fixed to the heat sink 410 by fasteners 201 and 301, respectively, and attached to a surface 411 of the heat sink 410, for example, so that the light distribution control component (210; 220) is at least partially or entirely located on one side of the circuit board 300 opposite the heat sink 400.

[0033] In one embodiment of the present disclosure, the light distribution control component (210; 220) can shape and emit light from the light source (110; 120) into a beam having a desired lighting function (e.g., low beam or high beam function). The structure of the light distribution control component will be further described below with reference to the accompanying drawings.

[0034] Optionally, in some embodiments, the lighting module may further include a light projection component for receiving the beam from the light distribution control component (210; 220) and providing or projecting a lighting beam having a desired lighting effect (e.g., intensity distribution or emission direction), such as a low beam and / or a high beam, which may be a parallel beam or a nearly parallel beam, toward, for example, the ground or an area in front of the vehicle. It will be understood that various types of light projection components may be employed in the present disclosure, including, but not limited to, various different arrangements of transmissive components, reflectors, or light guides. The illustrated embodiment describes an example in which a lens 500 is used as the light projection component, but the lens 500 may be attached to a lens bracket 600, which may also be attached to the same heat sink 400. In some examples, the optical axis of the light projection component (e.g., the lens 500) may be coincident with or parallel to the optical axis OO′ of the lighting module.

[0035] 1 and 5, the lens bracket 600 may have a frame-like structure including a hollow housing 601, which defines a window 605 for accommodating and mounting the lens 500, thereby allowing the beam shaped by the integrated light distribution control component (210; 220) to propagate through the hollow housing 601 and exit through the lens 500. The housing 601 may be formed with or provided with mounting legs 604 for being fixed to the heat sink 400, for example, so as to cover the light distribution control component, the circuit board, and the light source.

[0036] According to one embodiment of the present disclosure, the light distribution control component (210; 220) includes an integrated light collecting portion (211; 221) and a cutoff line forming portion (212; 222), wherein the light collecting portion (211; 221) is configured to collect light from the light source (110; 120) and direct it to the cutoff line forming portion (212; 222), and the cutoff line forming portion (212; 222) is configured to receive light from the light collecting portion (211; 221) and shape the light into an output beam having a cutoff line (e.g., a horizontal cutoff line). Therefore, the cutoff line forming portion and the light collecting portion are formed as an integrated part, that is, the two portions are integrated (e.g., molded) to form an integrated light distribution control component, which reduces material costs and manufacturing costs, eliminates the need to assemble the cutoff line forming portion, relaxes assembly requirements, saves space, and the relative position between the cutoff line forming portion and the light collecting portion is fixed and will not change due to any vibrations or other factors, ensuring a stable light distribution control effect.

[0037] As used herein, the terms "unitary" and "integrated" are used in contrast to "independent" or "separate" to mean that an integral or integrated component exists as a single entity and excludes parts that are spatially independent or separate from one another; for example, it will be understood that various parts of an integral or integrated component may be formed (e.g., molded) simultaneously or separately and then assembled together to form a single part.

[0038] In an exemplary embodiment, the light distribution control component can shape and guide light emitted from a light source by reflecting it, so at least one of its light concentrating portion and cutoff line forming portion may include a reflector or mirror, or may have a reflective surface or reflective coating. Specifically, the light concentrating portion may reflect light from the light source toward the cutoff line forming portion, and the cutoff line forming portion may reflect light from the light concentrating portion toward a desired or designed direction. For example, the light distribution control component may be molded from a highly heat-resistant material, such as glass or a polymer, for example, polycarbonate plastic (e.g., PC-HT) or polyetherimide, and the reflective surface may be formed by evaporating or coating metal on the surfaces of the formed light concentrating portion and cutoff line forming portion.

[0039] As an example, one or both of the light-collecting unit and the cutoff line forming unit may have one or more elliptical, parabolic, or semi-elliptical reflective surfaces. For example, the light-collecting unit may be a reflector at least partially facing the corresponding light source and cutoff line forming unit, with the light source located at or near the focal point of the light-collecting unit and the cutoff line forming unit located at or near the focal point of the light-collecting unit. As an example, the reflective surface of the light-collecting unit may be a surface obtained by rotating around an axis parallel to the optical axis of the lighting module. As described below, the reflective surface of the cutoff line forming unit may be formed with a cutoff line forming structure, for example, a raised edge or a stepped edge on a substantially horizontally extending edge. For example, light coming from the light-collecting unit and falling beyond the cutoff line forming structure is absorbed or blocked by other components of the lighting module rather than being emitted, thereby forming a bright and dark cutoff line in the output beam, for example, a stepped horizontal cutoff line that is lower on the left side and higher on the right side when viewed from the forward direction. This satisfies relevant regulations and driving safety requirements.

[0040] In the embodiments shown in Figures 1-2, 5-7, and 13-14, a single lighting module is integrated with two different lighting functions or can provide two different lighting beams, and the light distribution control component includes a first light distribution control component 210 and a second light distribution control component 220, which respectively realize two lighting functions, such as a low beam lighting function and a high beam lighting function. Correspondingly, the light source includes one or more first light sources 110 for emitting light to a first light distribution control component 210 and one or more second light sources 120 for emitting light to a second light distribution control component 220, where the first light distribution control component 210 is configured to shape the light from the first light source 110 into a first beam having a first cutoff line used for a first lighting function (as shown in FIG. 13), and the second light distribution control component 220 is configured to shape the light from the second light source 120 into a second beam having a second cutoff line used for a second lighting function (as shown in FIG. 14).

[0041] As an example, the first lighting function may be a low beam function and the second lighting function may be a high beam function, meaning that the first light distribution control component 210 is configured to provide a low beam, either alone or in conjunction with a light projecting component, and the second light distribution control component 220 is configured to provide a high beam, either alone or in conjunction with a light projecting component. Depending on the application, the first light source and the second light source may be independently activated to provide a low beam, a high beam, or a mixed or complementary beam that combines low and high beams, at different times, from a single lighting module.

[0042] In an exemplary embodiment of the present disclosure, a lighting module integrating two lighting functions may include only a single circuit board 300, with the first light source 110 and the second light source 120 mounted at an interval on the same circuit board 300, thereby reducing the number of connectors and wire harnesses used to connect two or more circuit boards and reducing the volume of the lighting module. As shown in Figures 5 to 7, the circuit board 300 may have a U-shaped contour defining an opening 310, with the first light source 110 and the second light source 120 mounted on two sides of the U-shaped opening, respectively.

[0043] In addition, a lighting module integrating two lighting functions may include only a single heat sink 400, and the circuit board 300 on which the first light source 110 and the second light source 120 are mounted, and the first light distribution control component 210 and the second light distribution control component 220 are also attached to the same heat sink 400, thereby further reducing the volume of the lighting module. The second light distribution control component 220 and the first light distribution control component 210 may be disposed on the same side of the circuit board 300 opposite to the heat sink 400.

[0044] In some other embodiments, as shown in Figures 3-4 and 8-12, a single lighting module may include only a first light distribution control component 210 for providing a low beam or only a second light distribution control component 220 for providing a high beam.

[0045] In one embodiment of the present disclosure, first light distribution control component 210 and second light distribution control component 220 are each formed as a single or integral component integrated with a light collecting portion and a cutoff line forming portion. When a single lighting module is integrated with a low beam lighting function and a high beam lighting function, first light distribution control component 210 and second light distribution control component 220 may be disposed adjacent to each other in a direction intersecting the optical axis OO′ of the lighting module (e.g., substantially perpendicular to or inclined with respect to the optical axis OO′) and substantially on opposite sides of the optical axis OO′ (see FIGS. 13 and 14 ).

[0046] In some applications, the lighting module may be slightly tilted within the housing of the lamp device according to the arrangement of the light distribution control component and the direction in which the emitted light is directed. For example, the surface 411 of the heat sink 400 for mounting the light distribution control component or circuit board 300 may be tilted at an angle θ with respect to the vertical direction or the focal plane (FP) of the light-projecting component (e.g., a lens). This allows the light from the light source to be shaped and guided by the light distribution control component, then projected from the light-projecting component and emitted over an appropriate distance ahead of the vehicle, without being projected downward at an excessively inclined angle toward the road surface too close to the vehicle, or upward at an excessively inclined angle. The angle θ can be appropriately set depending on the actual application, for example, in the range of 10° to 15°. In addition, such a tilt is convenient for mounting the light distribution control component and allows the light distribution control component to have an appropriate shape, such as a sloped surface shape that can be easily removed from a mold during manufacturing. In some embodiments, removal from the mold may be performed via a cutoff line forming portion.

[0047] In the illustrated embodiment, the first light distribution control component 210 includes the first light concentrating portion 211 and the first cutoff line forming portion 212 integrally (for example, by molding or manufactured by another method), and a gap or opening for allowing light to exit is defined between the first light concentrating portion 211 and the first cutoff line forming portion 212. In addition, the first light distribution control component 210 may include a first mounting base 213 extending from the first light concentrating portion 211 and attached to the heat sink 400 by the fastener 201; in this case, the first light concentrating portion 211 and the first cutoff line forming portion 212 may be spaced apart from the circuit board 300.

[0048] For example, the first light collecting portion 211 may include a dome-shaped reflector formed to have a first reflecting surface 2111, for example, an ellipsoid, a paraboloid, or a semi-ellipsoid, facing the inner wall of the first light source 110. As an example, the first light collecting portion 211 may be formed with a plurality of segments or reflecting surfaces, for example, concave surfaces, corresponding one-to-one to the plurality of first light sources 110.

[0049] As shown in the figure, the first cutoff line forming portion 212 may include a first main body 2121 and two first side surface connecting portions 2122 located on two opposing side surfaces of the first main body 2121, and the first side surface connecting portions 2122 extend from the first main body 2121 to the first light concentrating portion 211 so as to join or integrate the first light concentrating portion 211 and the first cutoff line forming portion 212. The first main body 2121 may have a plate shape spaced apart from the first light concentrating portion 211, and defines a gap or opening between the first main body 2121 and the first light concentrating portion 211 that allows light to exit to the outside, i.e., allows light to be reflected from the first light concentrating portion 211 without any or almost no obstruction by the first main body 2121. The surface of the first body 2121 facing the first light-concentrating portion 211 may be an elliptical, parabolic, or semi-elliptical reflective surface 2123 to reflect light from the first light-concentrating portion 211 outward.

[0050] The end of the reflective surface 2123 of the first cutoff line forming unit 212 may be formed as a stepped end with, for example, two horizontal flat portions, such that the first cutoff line forming structure 2124 from the first light collecting unit 211 falls over the cutoff line forming structure 2123, and the light coming from the first light collecting unit 211 and falling over the cutoff line forming structure 2123 is absorbed or blocked by other components of the lighting module or lamp apparatus instead of being emitted, thereby forming a bright and dark cutoff line in the emitted beam, for example, a stepped horizontal cutoff line or an upper cutoff line that is lower on the left side and higher on the right side when viewed from the front direction, thereby meeting relevant regulations and driving safety requirements.

[0051] In some embodiments, the first cutoff line forming structure 2124 configured to form a cutoff line for the low beam may be located at or near the focal plane (FP) of the light projecting element (e.g., lens 500) (as shown in Figures 13 and 14) to form a clear cutoff line for the low beam, while the remaining part of the reflecting surface 2123 of the first cutoff line forming portion 212 may be located upstream of the focal plane (FP) (i.e., upstream of light propagation along the optical axis OO').

[0052] Similarly, second light distribution control component 220 includes (for example, manufactured by molding or another method) integrated second light concentrating portion 221 and second cutoff line forming portion 222, with a gap or opening for emitting light defined between second light concentrating portion 221 and second cutoff line forming portion 222. In addition, second light distribution control component 220 may further include second mounting base 223 extending from second light concentrating portion 221 and attached to heat sink 400 by fastener 201; in this case, second light concentrating portion 221 and second cutoff line forming portion 222 may be spaced apart from circuit board 300.

[0053] For example, the second light collecting unit 221 may include a dome-shaped reflector formed to have a second reflecting surface 2211, such as an ellipsoid, a paraboloid, or a semi-ellipsoid, facing the inner wall of the second light source 120. As an example, the second light collecting unit 221 may be formed with a plurality of reflecting surfaces, for example, concave surfaces, corresponding one-to-one to the plurality of second light sources 120.

[0054] The second cutoff line forming portion 222 may include a second main body 2221 and two second side surface connecting portions 2222 located on two opposing side surfaces of the second main body 2221, and the second side surface connecting portions 2222 extend from the second main body 2221 to the second light concentrating portion 221 so as to join or integrate the second light concentrating portion 221 and the second cutoff line forming portion 222. The second main body 2221 has a plate shape, for example, and is spaced apart from the second light concentrating portion 221, defining a gap or opening between the second main body 2221 and the second light concentrating portion 221 that allows light to exit to the outside, i.e., allows light to be reflected from the second light concentrating portion 221 without any or almost no obstruction by the second main body 2221. The surface of the second body 2221 facing the second light-concentrating portion 221 may be an elliptical, parabolic, or semi-elliptical reflective surface 2223 to reflect light from the second light-concentrating portion 221 outward.

[0055] In some embodiments, at the end of the reflecting surface 2223 of the second cutoff line forming portion 222, as shown in the figure, the second cutoff line forming structure 2224 may be formed, for example, as a stepped end having two horizontal flat portions, so that the light coming from the second light collecting portion 221 and falling beyond the second cutoff line forming structure 2223 is absorbed or blocked by other components of the lighting module or the lamp apparatus instead of being emitted, thereby forming a bright and dark cutoff line in the emitted beam, for example, a stepped horizontal cutoff line that is lower on the left side and higher on the right side when viewed from the forward direction, thereby meeting relevant regulations and driving safety requirements.

[0056] In some embodiments, the second cutoff line forming structure 2224 configured to form a cutoff line for the high beam may be disposed near the focal plane (FP) of the light projecting component (e.g., the lens 500) (as shown in FIGS. 13 and 14), for example, near but downstream of the focal plane (FP), or at a position slightly offset from the focal plane (FP) in the optical axis direction, or within the focal plane (FP), thereby forming a substantially clear cutoff line for the high beam. The remaining majority of the reflecting surface 2223 of the second cutoff line forming portion 222 may be located upstream of the focal plane (FP).

[0057] In some embodiments, as shown in Figures 2, 6, 7, 13, and 14, the second light-concentrating portion 221 is arranged above the first light-concentrating portion 211, and the second cutoff line forming portion 222 is arranged mostly or entirely below the first cutoff line forming portion 212, in which case the second cutoff line forming portion 222 may be partially embedded in the first cutoff line forming portion 212, so that the second cutoff line forming portion 222 is at least partially exposed from a gap or opening defined between the first light-concentrating portion 211 and the first cutoff line forming portion 212, thereby allowing the light from the second light source 120 to be shaped and guided by the second light-concentrating portion 221 and the second cutoff line forming portion 222, and then emitted from the gap or opening between the first light-concentrating portion 211 and the first cutoff line forming portion 212.

[0058] As an example, a groove 2125 may be formed in the first body 2121 of the first cutoff line forming portion 212, similar to the lower part of the first body 2121, and the second side connection portion 2222 of the second cutoff line forming portion 222 is at least partially embedded in the groove 2125, but the reflecting surface 2223 of the second body 2221 of the second cutoff forming portion 222 is spaced from the first body 2121 of the first cutoff portion forming portion 222 (for example, its lower end portion), so that the light is reflected by the reflecting surface 2223 and then emitted at an appropriate angle.

[0059] Furthermore, as shown in Figures 2, 4, and 5, a groove 412 can be formed on the surface 411 of the circuit board 300 facing the heat sink 410, and the second cutoff line forming portion 222 can be positioned at least partially inside the groove 412, thereby making the structure more compact.

[0060] Although the present disclosure has been described in conjunction with the accompanying drawings, the embodiments disclosed in the drawings are intended to illustrate preferred embodiments of the present disclosure and should not be construed as limiting the present disclosure. The dimensional proportions in the drawings are merely schematic and should not be construed as limiting the present disclosure.
