Description

Technical Field

[0001] This invention relates to a lighting device for a trim piece. Furthermore, this invention relates to a trim piece for a motor vehicle and a motor vehicle. Background Technology

[0002] The installation of ambient lighting in motor vehicles, especially in the interior space, is becoming increasingly important. This should be actively pursued to enhance the user experience, envisioning users customizing their vehicles to their specific needs through the lighting fixtures. Generally, various variations of lighting fixtures exist, which can be installed in motor vehicles in different ways and for different purposes.

[0003] For example, a reading lamp is known from DE 10 2016 011 561 A1, which is housed in a spherical bracket and whose radiation direction can be adjusted by the user like a ball-and-socket joint.

[0004] Furthermore, DE 10 2018 108 278 A1 describes another concept for an adjustable lighting device. This device includes a light source having multiple semiconductor-based light sources in the form of light-emitting diodes (LEDs), which are collimated so that they each emit light cones in different directions. By appropriate manipulation, the light cones of multiple adjacent LEDs can be selectively overlapped to adjust the direction and intensity of the resulting overlapping light cones.

[0005] To achieve particularly attractive lighting effects, lighting devices feature multiple light-emitting elements, which are often installed over large areas in motor vehicles rather than in isolated locations. Each element can be individually controlled. This allows for the excellent rendering of sometimes dynamic patterns or large graphics.

[0006] However, the large-area installation of light-emitting components to generate dynamic lighting effects makes the manufacturing process difficult and expensive. Furthermore, these components are often difficult to recycle because the electronic components cannot be easily separated from the rest of the components. Therefore, the entire component is often disposed of as electronic waste. Summary of the Invention

[0007] The object of this invention is to provide an improved lighting concept, particularly for motor vehicles, which is especially capable of presenting large-area and / or dynamic lighting effects in a compact space.

[0008] In the type of lighting device described at the beginning, according to the present invention, this objective is achieved by the following means, namely, the lighting device has:

[0009] - Carrier,

[0010] - At least one light-emitting component fixed to a carrier.

[0011] - A mirror, which is fixed to a carrier by means of a reversibly deformable bracket of the lighting device and configured to deflect the emitted light, and

[0012] - A controllable deformable component that deforms the support structure.

[0013] The deformation of the bracket causes a change in the position of the mirror relative to at least one light-emitting element.

[0014] The carrier is used to fix at least one light-emitting element and a support. This fixing can be achieved in any manner. It is conceivable that the fixing is achieved by means of at least one additional fastener (e.g., a screw) and / or by bonding, welding, or brazing. Preferably, at least one light-emitting element is securely fixed to the carrier and configured to emit light in a single direction, preferably perpendicularly away from the carrier.

[0015] At least one light-emitting element is configured to generate and emit light. In principle, the light-emitting element can be any light-emitting element. Preferably, the at least one light-emitting element is an LED, especially an RGB-LED that can emit light of different colors.

[0016] As described above regarding the light-emitting element and the support, the mirror can be fixed to the support in any manner. Therefore, the support serves as a connector through which the mirror is fixed to the carrier. Furthermore, the support is reversibly deformable. That is, the support can deform from its initial shape to a target shape without damage or disruption, and can deform back to its initial shape. Since the support is the connector between the mirror and the carrier, deformation of the support causes a change in the position of the mirror relative to at least one light-emitting element. This change in position can also include a change in the orientation of the mirror relative to at least one light-emitting element. Therefore, such a change can include one or more translational and / or rotational relative movements.

[0017] Light emitted by at least one light-emitting element strikes a mirror and is deflected by the mirror. The way the mirror deflects the emitted light can be determined by, in particular, asymmetrical deformation of the support and the resulting change in the mirror's position relative to the at least one light-emitting element. Thus, targeted light deflection is achieved by means of the mirror through targeted support deformation. For this purpose, the lighting device has a controllable deformation element for targeted and controlled deformation of the support. As the deformation element, any component can be configured to apply targeted and controlled force to the support. To control the deformation element, the lighting device preferably has a control interface by means of which it can be connected to an external control device.

[0018] Therefore, the lighting device according to the invention has the advantage of producing a wide variety of lighting effects, especially dynamic lighting effects, with only a small number of light-emitting elements. Ideally, a single light-emitting element (i.e., just one LED) is sufficient. Thus, different, equally large-area, and dynamic lighting effects can be produced with a compact lighting device. This is achieved through the deformation of the support. Consequently, the mirror can be adjusted or repositioned relative to the light-emitting element, thereby producing different lighting patterns and dynamic lighting effects (e.g., a "spotlight" effect). The lighting patterns and effects can be projected onto, for example, the surface of a decorative element by means of light deflection achieved through the mirror. Thus, the need for the large-area installation of light-emitting elements common in the prior art is eliminated.

[0019] If the lighting device according to the invention comprises multiple light-emitting elements, these light-emitting elements are preferably arranged with a small spacing between them in only one area of ​​the carrier, i.e., locally concentrated. Thus, compared with known lighting devices, the manufacture of this lighting device can be significantly simplified and the cost is more reasonable. Furthermore, the smaller number of light-emitting elements and the local concentration of the light-emitting elements facilitate simplified recycling.

[0020] Preferably, the deformable component has at least one deformable actuator, particularly fixed to a carrier. The at least one deformable actuator enables precise and controllable movement, through which the support can be precisely deformed. Therefore, the mirror can be positioned with high precision relative to at least one light-emitting component. In principle, any controllable actuator can be used as the deformable actuator. Preferably, the at least one deformable actuator is an electronic or electromechanical actuator. For example, a bimetallic actuator or a solenoid is conceivable.

[0021] Particularly preferably, at least one deformation actuator is or includes a shape memory element, particularly a shape memory alloy wire. The shape memory element can, for example, easily deform from a defined first shape to a defined second shape by targeted energization. If the energization is interrupted, it automatically returns from the second shape to the first shape. Therefore, when using a shape memory element, control can be designed to be very simple. Control may only involve switching the current on and off.

[0022] In this regard, the use of so-called SMA wire (English: "shape memory alloy" or Formgedächtnislegierung, shape memory alloy) is particularly suitable. SMA wire can be deformed by applying an electric current. For example, SMA wire can take on a zigzag or accordion shape. If an SMA wire is energized, it contracts and shortens. If the current is interrupted, this causes the SMA wire to stretch again. This change in length can be used to selectively deform the support structure.

[0023] Preferably, a very fine but sufficiently stable SMA filament is used because a fine SMA filament can quickly return to its initial shape when the current is stopped. Therefore, in a feasible design, the SMA filament can have a diameter of less than 1 mm, less than 0.8 mm, or less than 0.6 mm. For example, the SMA filament can be energized using a pulse modulator.

[0024] The support may have at least one, particularly groove-shaped, receiving portion, wherein at least one deformable actuator extends at least partially within or in one of the receiving portions in a manner abutting against the support. At least one receiving portion is used for positioning and / or securing at least one deformable actuator relative to the support. The receiving portion can be understood as, in particular, a recess or groove that is at least substantially linear, in which at least one deformable actuator, or SMA wire, extends. Nevertheless, it is conceivable that the receiving portion or one of the receiving portions forms a latch around which at least one deformable actuator, in particular an SMA wire, is guided or suspended.

[0025] At least one receiving portion enables the connection of at least one deformable actuator to the support by simply "inserting" the deformable actuator into the receiving portion. Thus, the deformable actuator can be form-locked to the support simply by extending within the receiving portion. Alternatively or supplementarily, the deformable actuator can be glued to the receiving portion or secured by one or more fasteners (such as screws or clips).

[0026] Alternatively or supplementally, the support may have at least one retaining section, wherein at least one deformation actuator is fixed to the retaining section or one of the retaining sections. On each retaining section, one or more deformation actuators may be securely connected to the support. This connection may be achieved in any manner, such as by bonding, welding, or by additional fasteners.

[0027] At least one receiving portion and at least one retaining portion are preferably shape-stable to ensure a secure connection between the support and at least one deformable actuator, as well as defined force transmission. Each deformable actuator may be equipped with a corresponding receiving portion and / or a corresponding retaining portion.

[0028] Preferably, the deformable component has multiple deformation actuators. This allows for a particularly large deformation range that can be used to deform the support. Furthermore, the support can be deformed with exceptionally high precision using multiple deformation actuators. Simultaneously, a simpler deformation actuator that can only apply deformation force to the support in one direction can also be used.

[0029] It is conceivable that the deformable component has two deformation actuators fixed to the support in opposition to each other. These two deformation actuators can then function as mating elements. Therefore, the deformation range of the support can be increased, in particular, doubled. With the two opposing deformation actuators, the support can be deformed specifically in two opposite directions.

[0030] Alternatively, the deformable component may have three or more (especially four) deformation actuators evenly distributed around and fixed to the support. Each deformation actuator allows for targeted, and especially asymmetric, deformation of the support in at least one direction. The interaction of three or more deformation actuators enables a particularly large deformation range within which the support can deform more precisely.

[0031] Preferably, the support has at least one reset mechanism that generates a reset force when the support is deformed. This reset mechanism can be, for example, a spring or an elastic member acting as a spring. At least one return member is configured to restore the support to its initial shape after deformation and once the deformation actuator no longer applies a deformation force to the support. If a deformation force is applied to the support by the deformation actuator, this deformation force overcomes the reset force of the reset mechanism. If the support is no longer subjected to a deformation force, the support can return to its initial shape again through the reset force of the reset mechanism.

[0032] If multiple deformable actuators are provided, then supplementarily or alternatively, at least one of the deformable actuators can serve as a reset mechanism. Thus, for example, one deformable actuator can achieve compression while another deformable actuator achieves elongation, and vice versa.

[0033] Preferably, the support includes a shape-stable first component and a reversibly deformable second component, wherein the mirror is fixed to the first component, and the first component is fixed to the carrier by the second component such that deformation of the second component causes a change in the position of the first component and the mirror relative to at least one light-emitting element. In principle, the first component can be any shape-stable component capable of firmly fixing the mirror. For example, the first component can be a plastic or metal component. By fixing the first component to the second component on the carrier, the deformation range of the support is defined, thereby defining the space in which the mirror can be positioned relative to at least one light-emitting element.

[0034] It is conceivable that the second component includes at least one articulator that limits the deformation of the support within a defined range of deformation. Therefore, by means of at least one articulator, the movement of the mirror can be restricted to one or more defined movements, enabling precise positioning of the mirror.

[0035] Preferably, the second component is an elastic component, particularly one made of silicone / silicone resin. For example, the second component could be a silicone pad. Thus, the second component can function as a reset mechanism, eliminating the need for the additional reset mechanism described above. Silicone is relatively inexpensive and particularly heat-resistant. Silicone has exceptionally stable deformation properties, making it generally well-suited as a material for the second component. Alternatively or supplementarily, components made of rubber or foam, etc., can also be considered as the second component.

[0036] In a particularly preferred embodiment, the carrier is a circuit board. Thus, the carrier can have conductor tracks through which at least one light-emitting element and / or at least one deformable actuator can be controlled and / or energized. This allows for a particularly compact structure of the lighting device. The conductor tracks can be printed, thus the carrier is a PCB (printed circuit board). If the lighting device has a control interface, the control interface can be connected to at least one light-emitting element and / or at least one deformable actuator via the conductor tracks.

[0037] Preferably, the lighting device has a housing. The housing can enclose and protect the components of the lighting device. Furthermore, the housing facilitates the operation of the lighting device. The housing can be made of metal and / or plastic and / or ceramic as a one-piece or multi-piece assembly. The housing may have one or more fasteners for fastening to another component, such as a trim piece.

[0038] The housing may have one or more outlets for emitting light. At least one outlet is capable of targeted emission of light emitted by at least one light-emitting element and deflected by a mirror.

[0039] Additionally or alternatively, the housing may have at least one housing wall having at least one transparent or translucent wall segment capable of transmitting emitted light. At least one wall segment is at least partially translucent from the inside of the housing to its opposite outside. The support and mirror are configured to redirect the emitted light towards the inside of the wall segment at multiple defined locations. At least one wall segment may be fully or partially translucent. For example, the wall segment may be made of glass or plastic. The transmittance of at least one wall segment may be at least 0.4 or at least 0.6, and at most 1, wherein these transmittance limits are particularly relevant to the translucency of the wall segment when light is incident perpendicularly.

[0040] At least one outlet and / or at least one transmissive wall segment can act as a schablone, the shape of which pre-determines one or more generateable lighting effects. Advantageously, the housing may have multiple outlets and / or multiple transmissive wall segments. Through their arrangement relative to each other, different lighting effects and animations can be set, especially a "spotlight" effect.

[0041] It is also conceivable that the lighting device has at least one light modulator / dimmer, which is configured to shape the emitted light. The light modulator acts as a light shaper, and in principle, it can be configured for any type of light shaping, including light beaming or light scattering. Preferably, at least one light modulator is a lens. For example, the lens can be a convex lens or a concave lens. It is conceivable that the lighting device has multiple different or identical types of light modulators. At least one light modulator can be arranged between at least one light-emitting element and a mirror. Supplementally or alternatively, at least one light modulator can be arranged between the mirror and at least one wall segment or between the mirror and at least one housing opening. Furthermore, it is conceivable that one or more of the transmissive wall segments have or form light modulators. At least one light modulator can also be used to produce targeted lighting effects (e.g., a "spotlight" effect) by redirecting the emitted light toward the lens in different ways by changing the position of the mirror with the aid of a support.

[0042] A mirror can have one or more mirror surfaces, each of which is either flat, convex, or concave. Therefore, a mirror can be a multifaceted mirror. The number and shape of the mirror surfaces can influence the direction of light emitted through the mirror. If a mirror has multiple mirror surfaces, these surfaces can be at angles relative to each other. Depending on how the mirrors are positioned, the direction of light deflection on one or more of the mirror surfaces can be significantly altered. To achieve particularly simple deflection, at least one light-emitting element and the mirror can at least partially overlap, either perpendicularly or obliquely, relative to the direction in which light is emitted by the at least one light-emitting element.

[0043] In addition to the lighting device, the present invention also relates to a trim piece for a motor vehicle having at least one lighting device according to the invention. All the advantages and details described for the lighting device according to the invention also apply to the trim piece according to the invention, and vice versa.

[0044] Trim elements can be interior trim pieces, particularly door trim pieces. Lighting devices can be used, for example, to provide ambient lighting on the trim pieces and / or to create lighting effects and / or animations on the armrests of the door trim pieces. Alternatively, trim pieces can be body parts of the motor vehicle. For example, they can be door trim pieces, wherein lighting devices are configured to create lighting effects and / or animations on the ground where the vehicle is located when the door is open. Trim elements can also be front trunk lids or luggage compartment lids, wherein lighting devices are configured to create lighting effects and / or animations in the front trunk or luggage compartment.

[0045] The ornament may have at least one translucent outer layer, wherein the lighting device is arranged such that light emitted by at least one light-emitting element and deflected by a mirror is transmitted through the outer layer, wherein the position of the light passing through the outer layer can be adjusted by deformation of the lighting device support. The outer layer may be a cover or top layer of the ornament. The outer layer may be or include translucent fabric (especially textiles) or plastic, etc. The outer layer may consist of one or more layers, for example, also made of paint. Preferably, the outer layer is designed, especially to be mirror-finished and / or colored, such that at least one lighting device is not visible when the ornament is viewed from the outside when at least one light-emitting element is not emitting light.

[0046] Furthermore, the present invention relates to a motor vehicle having at least one lighting device according to the invention and / or at least one trim piece according to the invention. All the details and advantages described in conjunction with the trim piece according to the invention and the lighting device according to the invention also apply to the motor vehicle according to the invention, and vice versa. Attached Figure Description

[0047] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments. The drawings are schematic schematic diagrams, in which:

[0048] Figure 1 A front view of an embodiment of the lighting device according to the present invention is shown.

[0049] Figure 2 Showing a view from above Figure 1 Top view of an embodiment,

[0050] Figure 3 An example was shown crossing section line III-III. Figure 1 A cross-sectional view of an embodiment,

[0051] Figure 4 An embodiment of the ornament according to the invention is shown, and

[0052] Figure 5 An embodiment of a motor vehicle according to the present invention is shown. Detailed Implementation

[0053] Figures 1 to 3 A schematic embodiment of a lighting device 1 according to the present invention is shown. The lighting device includes a carrier 2 in the form of a circuit board 3. A light-emitting element 4 (currently an LED 5) is fixed on the carrier 2, and the light-emitting element is configured to emit light vertically 6 away from the carrier 2. This... Figure 3 The cross-sectional view is indicated by arrow 7.

[0054] In addition, the lighting device 1 includes a mirror 8, which is fixed to the carrier 2 by a bracket 9. Currently, the mirror 8 is convexly curved, and as... Figure 2 As shown in the top view, vertically 6 covers (in) Figure 2 (shown by the dashed line) Light-emitting element 4, so that the light emitted by light-emitting element 4 hits mirror 8 and is deflected by mirror (see...) Figure 3 Arrow 7 in the middle.

[0055] The support 9 is a reversibly deformable support. This support can be specifically deformed by the controllable deformable component 10 of the lighting device 1, thereby adjusting the position of the mirror 8 relative to the light-emitting component 4, such as... Figure 1 As shown by arrow 33. By changing the position of mirror 8 relative to the light-emitting element 4, the deflection of the light emitted by the light-emitting element 4 by mirror 8 can be adjusted.

[0056] Therefore, various lighting effects, even dynamic lighting animations, can be produced using only one light-emitting element 4 through the lighting device 1. The lighting device 1 is particularly compact and requires only a few components. Therefore, the manufacturing of this lighting device is simple and cost-effective. At the same time, the lighting device 1 enables the simplified recycling of the decorative components in which it is installed.

[0057] Currently, the deformable component 10 is a controllable deformation actuator 11, specifically an SMA wire 34, i.e., a shape memory component. The SMA wire 34 is fixed to the carrier 2 with its two ends 12 fixed and extends above the support 9. In other designs, multiple deformation actuators 11, especially SMA wires 34, can also be provided.

[0058] The support 9 consists of two parts. The support includes a shape-stable first component 13 made of plastic, which has a groove-shaped receiving portion 14 for the SMA wire 34, and the mirror 8 is securely fixed to the first component (see...). Figure 3 Furthermore, the support includes a reversibly deformable second component 15, through which the shape-stable first component 13 is fixed to the carrier 2. Currently, the second component 15 is a flexible silicone element that is form-locked with not only the first component 13 but also with the carrier 2 (see...). Figure 3 ).

[0059] like Figure 3 As shown, the SMA filament 34 extends through the groove-shaped receiving portion 14, thus engaging with the bracket 9 in a shape-locking manner. Currently, the SMA filament 34 has a wavy or accordion-like shape, which is not shown in the figure. If the SMA filament 34 is energized, it contracts. This causes the SMA filament to exert a deformation force on the bracket 9 vertically toward the carrier 2, compressing the second component 15 made of silicone. Therefore, the bracket 9 deforms from its initial position to a defined target position. Here, the second component 15 acts as a reset mechanism, generating a reset force to overcome the deformation force when the bracket 9 deforms due to the SMA filament 34. If the energization of the SMA filament 34 is interrupted, the SMA filament 34 elongates and therefore no longer exerts a deformation force on the bracket 9. Thus, the elastic second component 15, acting as a reset mechanism, restores the bracket 9 from the target position to its initial position.

[0060] like Figure 1 As shown, the shape of the bracket 9 is asymmetrical, so the SMA wire 34 can only apply a deformation force to the bracket 9 in the upper right corner of the figure. This causes the bracket to deform asymmetrically, i.e., it is compressed on the right side of the figure. This generates the rotational motion indicated by arrow 33, which allows the mirror 8 to rotate or tilt relative to the light-emitting element 4.

[0061] The control and power supply of the light-emitting element 4 and the SMA wire 34 are realized through a control interface (not shown), which is connected to the control interface by means of the conductor track of the circuit board 3 (i.e., the carrier 2).

[0062] like Figure 3 As shown, the lighting device 1 has a housing 16 that encloses and protects the described components. A translucent (i.e., transmissive) wall section 18 is provided in the housing wall 17 of the housing 16, through which light emitted and deflected by the mirror 8 (see arrow 7) can pass and exit from the housing 16. As a supplement to or alternative to the transmissive wall section 18, the housing 16 may have one or more exit ports.

[0063] The lighting device 1 also includes a light modulator 19 (here, a lens 20) for shaping the emitted light. In this embodiment, the transmissive wall section 18 is formed by the lens 20. The lighting device 1 may also have an additional light modulator 19, which may be disposed between the light-emitting element 4 and the mirror 8 or between the mirror 8 and the wall section 18.

[0064] In another embodiment, the bracket 9 may have one or more retaining sections on which one or more deformable actuators 11 may be securely fixed. The bracket 9 may also have multiple receiving portions 14 through which the deformable actuators 11 are guided for connection to the bracket 9, such as tabs or collars. The lighting device 1 may have two opposing deformable actuators 11 fixed to the bracket 9. The lighting device may also have three or more deformable actuators 11 evenly distributed around the bracket 9 and fixed to it. Furthermore, the second component 15 need not be an elastic component, but may also include multiple rigid components connected by one or more joints / hinges. To return the bracket 9 to its initial position, an additional reset mechanism, such as a spring, may be provided.

[0065] Figure 4 A vehicle door 35 is shown, which has one embodiment of a trim piece 21 according to the invention. The trim piece has, according to... Figures 1 to 3 The lighting device 1 is an embodiment of the lighting device 1. The trim piece 21 is a door interior trim piece 22. The trim piece includes an outer layer 23, which forms a transmissive wall section 18 of the lighting device 1. Light emitted by the light-emitting element 4 and deflected by the mirror 8 is transmitted through the outer layer 23 and projects onto the armrest 24 of the door 35 (indicated by beam 36). The position where the light is transmitted through the outer layer 23 can be adjusted by deforming the bracket 9 of the lighting device 1. Therefore, the armrest 24 can be illuminated in different positions, and a dynamic light effect can be produced (indicated by arrow 37).

[0066] In addition, Figure 5 An embodiment of a motor vehicle 32 according to the present invention is shown. In the interior space 25, various trim pieces 21 (including door trim pieces 22, body pillar trim pieces 26, and instrument panel trim pieces 27) are installed with... Figures 1 to 3 The example lighting device 1. In addition, the motor vehicle 32 includes a front trunk 28 with a front trunk lid 29 (in which the lighting device 1 is provided) and a trunk 30 with a trunk lid 31 (in which the lighting device 1 is installed).
