Description

[Technical Field]

[0001] FIELD Embodiments of the present disclosure relate generally to the field of lighting and / or signaling, and more particularly to a lighting module that can reduce manufacturing costs, and a lamp apparatus and a vehicle including such a lighting module. [Background technology]

[0002] Various lamp devices that provide light for illumination or signaling are known in various fields. For example, vehicle lamps are used to provide illumination or signaling functions in vehicles, to ensure safe driving, or to provide decorative functions.

[0003] For example, in vehicle applications, the light collector commonly used for low beam and the light collector for high beam are independent components and are assembled separately; even in a lighting module with dual functions of high beam and low beam, the low beam collector and the high beam collector are also independent components and are assembled separately, which results in high material costs and manufacturing costs for the independent components, high assembly precision requirements, and the need for additional connectors, wiring harnesses, circuit boards, mounting components, etc., which further occupy the assembly space in the vehicle lamp, which leads to a larger volume of the vehicle lamp.

[0032] Specific Embodiments

[0023] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. In this description, 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 generally describe the disclosed concepts of the present disclosure and should not be construed as a limitation of the present disclosure.

[0033] Furthermore, in the following detailed description, for ease of explanation, numerous specific details are set forth in order 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 illustrative form to simplify the drawings.

[0034] 1-11 schematically illustrate the structure of an illumination module according to an exemplary embodiment of the present disclosure. The illumination module can function as a component of a lamp device, guiding light from a light source to be emitted with a desired illumination effect (e.g., a desired intensity distribution or direction) to achieve a lighting function or a signaling function. As an example, the lamp device may be mounted on a vehicle as a vehicle lamp, including, but not limited to, headlights such as dipped headlights and full-power headlights, e.g., integrated high and low beam vehicle lamps, or vehicle lamps providing other lighting functions. It is understood that in addition to the illumination module, the lamp device may further include other components not shown, such as a housing for accommodating the illumination module, an optional light distribution screen, a connector, and mounting / positioning elements. The term "vehicle" as used herein refers to any type of vehicle, such as a motor vehicle, a motorcycle, or any other mobile machine capable of carrying at least one occupant or used to transport people or goods.

[0035] In the illustrated embodiment, the lighting module mainly includes a first light source 110, a second light source 120, an integrated light collecting unit 200, a first reflecting unit 500, and a second reflecting unit 430. In the exemplary embodiment of the present disclosure, the first light source 110 and the second light source 120 can generate light for different lighting functions, such as a low beam function and a high beam function, and may include any suitable light-emitting device, such as a halogen bulb, a xenon lamp, an LED, and a laser. Depending on actual requirements, the lighting module may include one or more first light sources 110 and / or one or more second light sources 120 arranged in various forms. For example, a single lighting module may be integrated with two different lighting functions or provide two different lighting luminous fluxes.

[0036] The light source of the lamp device or lighting module can be disposed on the carrier. For example, the lighting module can further include a circuit board 300, for example a PCB, and the first light source 110 and the second light source 120 for providing different lighting functions can be mounted on the same circuit board 300.

[0037] Illustratively, the light collecting unit 200 is configured to collect light from the first light source 110 and the second light source 120 and direct the light toward the corresponding first reflecting unit 500 and second reflecting unit 430, which in turn reflect the light from the light collecting unit 200 toward the light projecting components. In some examples, as described below, the first reflecting unit or the second reflecting unit may be formed with a cutoff line forming structure for forming a cutoff line in the light flux exiting the lighting module.

[0038] In order to timely and effectively dissipate heat from the lighting module (e.g., its light sources or other heat-generating components), the lighting module may further include a heat sink 400. For example, the heat sink 400 includes a heat dissipation plate 410 for heat conduction and a plurality of heat dissipation fins 420 extending from the heat dissipation plate 410, and the circuit board 300 supporting the first light source 110 and the second light source 120 and the light concentrator 200 may be provided on a mounting surface 411 of the heat dissipation plate 410, for example, by fasteners (not shown), so that the light concentrator 200, the first light source 110, and the second light source 120 are all disposed on a side of the circuit board 300 away from the heat sink 400.

[0039] In an embodiment of the present disclosure, the light collecting unit 200 cooperates with the first reflecting unit 500 and the second reflecting unit 430 to shape the light from the first light source 110 and the second light source 120 into a beam having a desired illumination function (e.g., low beam function or high beam function) for emission. The structures of the light collecting unit and the reflecting unit will be described in detail below with reference to the drawings.

[0040] Optionally, in some embodiments, the lighting module may further comprise a light projection component that receives the beam from the first reflecting portion 500 and / or the second reflecting portion 430 and provides or projects an illumination beam, such as a low beam and a high beam, with a desired lighting effect (e.g., intensity distribution or emission direction), e.g., towards the area in front of the vehicle or the ground, which may be a parallel or nearly parallel beam.

[0041] It is understood that various forms of light projection components may be employed in the present disclosure, including, but not limited to, various different arrangements of transmitting components, reflectors, or light guides. In the illustrated embodiment, the light projection component includes a lens 610, which may be mounted to a lens bracket 620, which may also be mounted to the same heat sink 400. As a non-limiting example, as shown in FIGS. 10 and 11 , the lens 610 may include a biconvex lens having two convex surfaces 611 and 612. In some examples, the optical axis of the light projection component (e.g., lens 610) may be coincident with or parallel to the optical axis O-O' of the lighting module.

[0042] 1 and 5, the lens bracket 620 may have a frame-shaped structure and include a hollow housing defining a window 621 for receiving and mounting the lens 610, allowing the beams formed by the light collecting portion 200, the first reflecting portion 500, and the second reflecting portion 430 to travel through the hollow housing, pass through the lens 620, and exit at the same window. The lens bracket 620 may be formed or provided with mounting feet 626, for example, for fastening to a jack 406 formed in the heat sink 400, such that the lens bracket 620 covers the light collecting portion 200, the first reflecting portion 500, the second reflecting portion 430, the first light source 110, and the second light source 120.

[0043] According to an embodiment of the present disclosure, the light collecting unit 200 is an integrated or single component comprising an integrated first light collecting portion 210 and a second light collecting portion 220, where the first light collecting portion 210 is configured and arranged to collect light from the first light source 110 and direct the light towards the first reflecting portion 500, while the second light collecting portion 220 is configured and arranged to collect light from the second light source 120 and direct the light towards the second reflecting portion 430. Thus, the first light collecting portion and the second light collecting portion providing different illumination functions are formed into an integrated component, meaning that the two portions are integrated into an integrated light collecting unit, which may reduce material costs, manufacturing costs, ease assembly requirements, and save space.

[0044] The terms “integral” and “integrated” are used herein in contrast to “independent” or “separate” and should be understood to mean that an integral or integrated component exists as a single entity, eliminating spatially independent or separate portions from one another; for example, various portions of an integral or integrated component may be formed (e.g., molded) simultaneously or separately and then assembled together to form a single component. Preferably, first light collecting portion 210 and second light collecting portion 220 are formed as a single unit using the same material through a molding process, which may reduce material and manufacturing costs, reduce assembly requirements, and save space. In another example, the two light collecting portions may be formed separately and then secured together with buckles, threads, or other means, which may also save space.

[0045] The first reflecting portion 500 is configured and arranged to reflect light from the first light collecting portion 210 to form a first light beam for emission (see FIG. 10), while the second reflecting portion 430 is configured and arranged to reflect light from the second light collecting portion 220 to form a second light beam for emission (see FIG. 11).

[0046] In an exemplary embodiment, the light collecting portion may shape and direct light generated from the light source in a reflective manner, and at least one of the first light collecting portion and the second light collecting portion may include a reflector or mirror, or may have a reflective surface, or a reflective coating or plating. Specifically, the first light collecting portion 210 may reflect at least a portion of the light from the first light source 110 toward the first reflector 500, which may reflect the light from the first light collecting portion 210 outward in a desired or designed direction to form a first light flux for a first lighting function. The second light collecting portion 220 may reflect at least a portion of the light from the second light source 120 toward the second reflector 430, which may reflect the light from the second light collecting portion 220 outward in a desired or designed direction to form a second light flux for a second lighting function.

[0047] For example, one of the first and second light beams is a low beam, and the other is a high beam. However, the present disclosure is not limited thereto, and the first or second light beam may be a light beam used for other lighting functions, such as daytime running lights, parking lights, fog lights, and brake lights. For example, the combination of the first light-collecting portion 210 and the first reflector may provide a low beam, either alone or in conjunction with a light-projecting component, while the combination of the second light-collecting portion 220 and the second reflector 430 may provide a high beam, either alone or in conjunction with a light-projecting component. Depending on the specific application, the first and second light sources may be separately activated to provide a low beam, a high beam, or a mixed or complementary light beam formed by a combination of low and high beams at different times through a single lighting module. As an example of a mixed or complementary light beam, the low beam and the high beam may partially coincide or overlap when emitted.

[0048] 9-11, the first light concentrating portion 210 may have a first reflecting surface 211 facing both the first light source 110 and the first reflecting portion 500, and the second light concentrating portion 220 may have a second reflecting surface 221 facing both the second light source 120 and the second reflecting portion 430. Correspondingly, the first reflecting portion 500 has a third reflecting surface 503 for receiving and reflecting light from the first reflecting surface 211, and the second reflecting portion 430 has a fourth reflecting surface 431 for receiving and reflecting light from the second reflecting surface 221.

[0049] For example, the first and second light-collecting portions may be made of a material that is resistant to high heat, such as molded from glass or polymers such as polycarbonate plastic (e.g., PC-HT) or polyetherimide, and their reflective surfaces may be formed by metallizing or coating or plating the surfaces of the formed light-collecting portions.

[0050] For example, at least one of the first to fourth reflecting surfaces may include one or more curved surfaces (such as elliptical, parabolic, or semi-elliptical) or flat reflecting surfaces, and the curved reflecting surfaces may shape the light into a desired profile. For example, the reflecting surface of the light-collecting portion may be a surface obtained by rotating it about an axis parallel to the optical axis of the lighting module, such as a concave surface. For example, as shown in FIGS. 2, 3, 5-7, and 9-11, the first light-collecting portion 210 may include a reflecting portion at least partially facing the corresponding first light source 110 and the first reflecting portion 500, and the first light source 110 may be positioned at or near the focal point of the first light-collecting portion 210 or the reflecting portion, such that the first light-collecting portion 210 or the reflecting portion may reflect light from the first light source 110 to the first reflecting portion 500 in a substantially collimated manner, thereby improving optical efficiency; similarly, the second light-collecting portion 220 may include a reflecting portion at least partially facing the corresponding second light source 120 and the second reflecting portion 430, and the second light source 120 may be positioned at or near the focal point of the second light-collecting portion 220 or the reflecting portion, such that the second light-collecting portion 220 or the reflecting portion may reflect light from the second light source 120 to the second reflecting portion in a substantially collimated manner, thereby improving optical efficiency. As shown, the inner wall of the first light collecting portion 210 or reflecting portion defines a first reflecting surface 211 and the inner wall of the second light collecting portion 220 or reflecting portion defines a second reflecting surface 221 .

[0051] 2-3, 5-7, and 9-11, the first light collecting portion 210 and the second light collecting portion 220 are spaced apart from each other in a direction intersecting the optical axis O-O' of the illumination module (e.g., a direction substantially perpendicular or inclined to the optical axis O-O') (see FIGS. 10 and 11), and define a light outlet 201 therebetween that allows the first light beam and the second light beam to be emitted separately or simultaneously. The light collecting portion 200 may further include two side connection portions 230 located on opposite sides of the light outlet 201, each extending from the first light collecting portion 210 to the second light collecting portion 220, whereby the first light collecting portion 210, the second light collecting portion 230, and the side connection portion 230 form an integral component with the intermediate light outlet 201.

[0052] The third reflecting surface 503 of the first reflecting portion 500 and the fourth reflecting surface 431 of the second reflecting portion 430 are both partially exposed from the light outlet 201 to allow the reflected light beam to exit from the light outlet 201. In the illustrated embodiment, a slot 232 is formed in each side connection portion 230, and the first reflecting portion 500 is partially inserted into the slot 232 and fixed. For example, as shown in FIGS. 2, 3 and 5 to 9, the first reflecting portion 500 includes a plate-shaped reflecting body 501 and plug-in side portions 502 arranged on opposite sides of the reflecting body 501, the reflecting body 501 defining a third reflecting surface 503 facing the first light collecting portion 210, and the plug-in side portions 502 are configured to be inserted into the slits 232 of the side connection portions 230 and fixedly positioned. As shown in Figures 2, 3, 6 and 8, one end 506 of the plug-in side part 502 is pressed against a stop part 236 arranged near the slit 232 of the side connection part 230, while the opposite end of the plug-in side part 502 is formed with a shoulder 505 and a retaining part 235 is provided on the side wall of the slot 232, which can be pressed against the shoulder 505 to retain the plug-in side part 502 in the slot 232.

[0053] In some embodiments, as shown in FIGS. 3 and 9-11, the first light-collecting portion 210 and the second light-collecting portion 220 may be disposed on opposite sides of the first reflecting portion 500 or its reflecting body 501, while the fourth reflecting surface 431 of the second reflecting portion 430 is spaced apart from the reflecting body 501 and has a portion located on the same side of the reflecting body 501 as the first light-collecting portion 210 and another portion located on the other side of the reflecting body 501 as the second light-collecting portion 220, so that light from the second light-collecting portion 220 at the back surface of the reflecting body 501 may be reflected for emission through the gap between the reflecting body 501 and the first light-collecting portion 210 (i.e., the portion of the light outlet 201).

[0054] In some embodiments, as shown in Figures 2, 5, 8, 10 and 11, the reflective body 501 of the first reflective portion 500 may be formed with a first cutoff line forming structure 504, which is configured to shape a portion of the light from the first light concentrating portion 210 so as to form or provide a first cutoff line, e.g., a horizontal cutoff line, in the emitted first light flux. For example, the third reflecting surface 503 of the reflecting body 501 may be formed with a first cutoff line forming structure 504 at a substantially horizontally extending edge (a lower edge in the drawing), such as a protruding edge or a stepped edge having two horizontal flat portions, and light from the first light concentrating portion 210 that falls beyond the first cutoff line forming structure 504 is not emitted but is absorbed or blocked by other components of the lighting module, thereby forming a bright or dark cutoff line in the emitted first light flux, 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, thereby satisfying relevant regulations and driving safety requirements. Similarly, the second reflecting portion 430 may be formed with a second light ray cutoff line forming structure for providing a cutoff line in the emitted second light flux, which is formed at or defined by, for example, a lower edge 432 of the fourth reflecting portion 431.

[0055] In some examples, the first cutoff line forming structure 504 configured to form a cutoff line for a low beam may be disposed in or near the focal plane (FP) of the light projection component (e.g., lens 610) (as shown in FIGS. 10 and 11 ) to form a clear cutoff line in the low beam, while the remaining part of the first reflecting surface 503 of the first reflecting portion 500 may be disposed downstream of the focal plane (FP) (i.e., downstream of light propagation along the optical axis O-O′). In some examples, the second cutoff line forming structure configured to form a cutoff line for a high beam may be disposed near the focal plane (FP) of the light projection component (e.g., lens 610), for example, disposed near but downstream of the focal plane (FP) or slightly offset from the focal plane (FP) in the optical axis direction, or may be disposed within the focal plane (FP), thereby forming a substantially clear cutoff line in the high beam, while the remaining most part of the fourth reflecting surface 431 of the second reflecting portion 430 may be disposed upstream of the focal plane (FP).

[0056] In an exemplary embodiment of the present disclosure, a lighting module integrated with two lighting functions may include a single circuit board 300, with the first light source 110 and the second light source 120 spaced apart on the same circuit board 300, thereby reducing the number of connectors and wiring harnesses used to connect two or more circuit boards and reducing the size and cost of the lighting module. As shown in FIGS. 5-7, the circuit board 300 has a U-shaped profile defining an opening 310, and the first light source 110 and the second light source 120 are mounted on either side of the U-shaped opening. As shown in FIGS. 2, 4, and 5, only a single connector 320 is provided on the circuit board 300 to supply power / transmit signals to the circuit board.

[0057] Furthermore, the lighting module integrating the two lighting functions may only include a single heat sink 400, a circuit board 300 on which the first light source 110 and the second light source 120 are provided, and a light collector 200 attached to the mounting surface 411 of the same heat sink 400, which allows for further reduction in the volume of the lighting module.

[0058] As shown in FIGS. 2 to 7 , the light-concentrating portion 200 may further include a mounting base 240 connected to the first light-concentrating portion 210 and the second light-concentrating portion 220, and the mounting base 240 may have mounting holes 202 formed therein, the circuit board 300 may have corresponding mounting holes 302 formed therein, and the heat sink 400 may have corresponding mounting holes 402 formed therein, and the light-concentrating portion 200 and the circuit board 300 may be attached to the heat sink 400 by inserting fasteners (not shown) into the aligned mounting holes 202, 302, and 402. In some examples, positioning holes 303 may be further formed in the circuit board 300, positioning grooves 403 may be formed on the edge of the mounting surface 411 of the heat dissipation plate 410, and positioning posts 203 may be formed on one side of the light concentrator 200 facing the circuit board 300, and the positioning posts 203 are inserted into the aligned positioning holes 303 and positioning grooves 403, thereby fixing the relative positions among the light concentrator 200, the circuit board 300, and the heat sink 400. In other examples, limiting posts 404 are formed on the edge of the mounting surface 411 of the heat dissipation plate 410, and limiting holes 304 are formed on the edge of the circuit board 300, and after assembly, the limiting posts 404 are positioned in the limiting holes 304 to prevent the circuit board 300 from moving relative to the heat sink 400.

[0059] In some applications, depending on the arrangement of the light collector and reflector and the direction in which the light is guided, the lighting module may be slightly tilted within the housing of the lamp unit, for example, the mounting surface 411 of the heat sink 400 or the circuit board 300 may be tilted at an angle θ relative to the vertical or the focal plane (FP) of the light projection components (e.g., lenses) (see FIGS. 10 and 11 ), so that the light from the light source is guided by the light collector and reflector and projected from the light projection components to emit over an appropriate distance in front of the vehicle, rather than projected downward at an excessively oblique angle toward the road surface immediately in front of the vehicle or projected upward at an excessively oblique angle. The angle θ may be appropriately set according to the actual application, for example, within a range of 10° to 15°. Furthermore, such a tilt is convenient for providing the light collector and reflector.

[0060] In the illustrated embodiment, the second reflecting portion 430 is formed on the side of the heat dissipation plate 400 facing the circuit board 300. This means that the second reflecting portion 430 is formed as a part of the heat dissipation plate 400, thereby reducing the number of parts of the lighting module so as to reduce assembly difficulty and improve compactness. For example, as shown in FIGS. 2 to 5 and 9, the second reflecting portion 430 may include or be formed as a rib that partially protrudes from the mounting surface 411 of the heat dissipation plate 400. However, the present disclosure is not limited thereto. In other embodiments, the second reflecting portion may be separately disposed depending on the actual application. The relative positions between the first reflecting portion, the second reflecting portion, and the light collecting portion are not limited to the arrangements shown in the figures and may be appropriately set. For example, if the output window is sufficiently large, the second reflecting portion may be disposed above the first reflecting portion.

The dimensional proportions in the drawings are merely approximate and should not be construed as limiting the present disclosure.

[0062] While several embodiments of the general concepts of the present disclosure have been shown and described, those skilled in the art will understand that changes can be made to these embodiments without departing from the principles and spirit of the general concepts of the present disclosure. The scope of the present disclosure is defined by the claims and their equivalents.
