Description

[0001] The present disclosure generally relates to a lighting device. More specifically, the present disclosure relates to a lighting device for a vehicle interior and a vehicle having the lighting device.

[0002] Lighting devices for vehicle interiors are known. Lighting devices with LEDs (light-emitting diodes) as light sources are also known. These lighting devices can be designed to illuminate vehicle interiors and / or as decorative or accent lighting. Lighting devices for generating multiple patterns, particularly to create volumetric or infinity effects, are also known. The creation of such visual effects generally makes the lighting devices more complex and increases the required installation space. Furthermore, the known lighting devices are limited in their functionality and design options.

[0003] An object of the embodiments of the present disclosure is to provide a visually appealing lighting device with a small installation space and with greater design freedom for an interior of a vehicle.

[0004] To achieve this object, according to a first aspect, a lighting device for the interior of a vehicle is provided. The lighting device comprises a housing, a lighting element for generating a lighting structure within the housing, and at least one light source for illuminating the lighting element. In particular, the housing can comprise one or more viewing windows so that the lighting structure within the housing can be visually perceived from the outside, in particular by vehicle occupants. The at least one light source can in particular comprise one or more lighting means and be designed to illuminate the lighting element by illuminating the lighting element. The lighting device further comprises a mirror arrangement, wherein the mirror arrangement is designed such that images of the lighting structure can appear at different positions or at different depth levels within the housing, in particular multiple times.The appearance of the luminous structure at different positions or depth levels can create not only a volume effect but also a visual infinity effect, in particular an illusion of infinitely repeating structures.

[0005] The mirror arrangement comprises at least one adjustable mirror, allowing the positions of images to be varied. By varying the positions of images of the luminous structure within the housing, any number of individually adjustable illumination states of the luminous device can be realized. Changing the positions of images can also create a particularly appealing variable volume effect.

[0006] The housing can comprise a substantially axially symmetric side wall and a flat housing base. The at least one light source can be arranged in a substantially planar manner on an inner side of the flat housing base. In particular, the light source can comprise a circuit board arranged in a planar manner on the flat housing base, with a number of LEDs distributed over the surface of the circuit board. The planar structure of the light source on the housing base allows the overall design of the lighting device to be simplified, and the overall dimensions of the lighting device, particularly in the radial direction, can be reduced.

[0007] The luminous element and the mirror arrangement can be arranged axially downstream of the at least one light source and can be configured to be substantially plane-parallel to the housing base. The plane-parallel configuration of the components of the lighting device can, in particular, ensure that the images of the luminous structure repeat at regular intervals.

[0008] The at least one adjustable mirror of the mirror arrangement can be mounted displaceably, in particular along an axis of symmetry or an optical axis of the lighting device. By displacing the at least one mirror along the optical axis of the lighting device, the axial positions at which the images appear can be varied, so that depth effects of varying intensity can be created.

[0009] The at least one adjustable mirror of the mirror arrangement can be pivotably mounted. In particular, the at least one adjustable mirror can be designed to be tilted relative to the optical axis of the lighting device. By tilting the at least one adjustable mirror, the images of the lighting structure can be shifted laterally or radially, creating the illusion of a curved space inside the housing.

[0010] By shifting and tilting at least one adjustable mirror, a particularly appealing volume effect with variable depth and variable spatial curvature can be realized.

[0011] The mirror arrangement can comprise a substantially non-transparent or opaque mirror with a mirror surface facing the at least one adjustable mirror. In particular, the mirror arrangement can be designed such that the light emitted by the luminous element and reflected back within the mirror arrangement by the at least one adjustable mirror is reflected back forward by the mirror surface of the non-transparent mirror. The resulting multiple reflections can enhance the visual effect of the repeating structures.

[0012] The substantially non-transparent mirror can rest against the luminous element with a side facing away from the at least one adjustable mirror. In particular, the non-transparent mirror can be designed such that at least a portion of the luminous element is covered by the non-transparent mirror, whereby an uncovered portion of the luminous element can appear as a structured luminous element or as a light structure. Thus, the non-transparent mirror can be used both to generate multiple reflections in the mirror arrangement and to generate the light structure.

[0013] The at least one adjustable mirror can be designed as a partially transparent mirror arranged downstream of the essentially non-transparent mirror. The at least one partially transparent mirror can, in particular, have a certain degree of transparency. In particular, the partially transparent mirror can be designed such that a certain portion of the light incident on the partially transparent mirror is transmitted. A certain portion of the incident light can be reflected back onto the non-transparent mirror for further reflection. Thus, a type of light recycling can occur repeatedly, in particular until the light reaches the outside. The proportion of light reflected by the partially transparent mirror determines the light recycling efficiency and influences the relative brightness of the luminous structures appearing at different depth levels.

[0014] Depending on the design, the semi-transparent mirror can have a transparency between 20% and 80%, in particular between 40% and 60%, and especially between 45% and 55%. In particular, the choice of transparency can be based on the design requirements of the lighting device. In some embodiments, the semi-transparent mirror has a transparency of approximately 50%, which enables a high degree of light recycling with a high luminous efficacy, particularly sufficient for many applications.

[0015] The partially transparent mirror can be designed in the form of a mirror film and / or a mirror layer or coating on a substantially light-permeable, particularly translucent and / or transparent, support. The support can serve both to hold the mirror film and as an optical element for influencing the luminous properties of the lighting device. The support of the partially transparent mirror can simultaneously function as a cover plate or as a light exit window of the lighting device.

[0016] In some embodiments, the carrier has a transmittance of more than 50%, in particular more than 80%, specifically more than 85%, even more specifically more than 89%. In some embodiments, the carrier is made of plastic, for example, polycarbonate. The transmittance of the carrier can be selected, in particular, based on the design requirements. In some versions, the carrier has a structuring or inscription, which, particularly in combination with a high transmittance of the carrier, can appear as if it were floating in space on the front of the lighting device.

[0017] According to a second aspect, a vehicle is proposed. The vehicle has at least one interior with at least one lighting device according to the first aspect for the lighting design of the interior of the vehicle. Due to the variable visual volume or infinity effect of the at least one lighting device, the vehicle offers the vehicle occupants an appealing interior design and an overall improved driving experience.

[0018] The invention will now be explained in more detail with reference to the accompanying figures. The same reference numerals are used throughout the figures for identical or equivalent parts. Fig. 1 shows schematically a lighting device according to an embodiment in different views, Fig. 2 shows a schematic cross section of the lighting device according to Fig. 1 in a first state, Fig. 3 shows a schematic cross section of the lighting device according to Fig. 1 in a second state, Fig. 4 shows a schematic cross section of the lighting device according to Fig. 1 in a third state, Fig. 5 shows a schematic cross section of the lighting device according to Fig. 1 in a fourth state. Fig. 6 shows a schematic cross section of the lighting device according to Fig. 1 in a fifth state, Fig. Figure 7 shows schematically the lighting device according to Fig. 1 in an exploded view, Fig. Figure 8 shows schematically the lighting device according to Fig. 1 in a first exploded partial view, Fig. 9 shows schematically the lighting device according to Fig. 1 in a second exploded partial view, and Fig. 10 shows schematically a perspective view of the lighting device according to Fig. 1 in operation.

[0019] Fig. 1 schematically shows a lighting device according to an embodiment in different views. In particular, Fig. 1 a front view (top center of the image), a side view (top right of the image) as well as a perspective view (bottom left of the image) and a top view (bottom center of the image).

[0020] The lighting device 1 comprises a housing 3 and a number of light sources 2, wherein the light sources are arranged on a carrier plate 4 or carrier board on the bottom of the housing 2. The light sources 2 and the carrier plate 4 are in Fig. 1. The light sources 2 are designed as LEDs or LED light sources and are arranged essentially circularly on the carrier board 4. The housing 3 is essentially axially symmetrical and has an octagonal cross-section and an octagonally shaped base. The carrier plate 4 also has an octagonal layout and is designed to match the housing base, see, for example, the exploded view of the Fig. 7 below.

[0021] The lighting device 1 further comprises a front mask 6 with a light trap 6a. The front mask 6 is particularly clearly visible in the side view, the perspective view, and the top view. The front mask 6 is designed in the shape of a tube with an octagonal opening cross-section and has a flat base and a profile that tapers upwards in the side view. The light trap 6a is formed at the base of the light mask 6, so that the opening cross-section of the light mask 6 is restricted at the base.

[0022] The lighting device 1 further comprises a movably mounted or adjustable cover plate 8 or support. The cover plate 8 has a partially transparent mirror (in Fig. 1 not visible) in the form of a mirror coating. The partially transparent mirror can also be designed as a mirror film laminated to the cover plate. Fig. Figure 1 also shows an adjustment lever 14 for adjusting the movably mounted cover plate 8 and thus also the semi-transparent mirror. The adjustment lever 14 has an ergonomically shaped head with a rounded tip.

[0023] Fig. 2 shows a schematic cross section of the lighting device according to Fig. 1 in a first state. In the cross section of the Fig. 2 the internal structure of the lighting device 1 can be seen particularly well.

[0024] In the exemplary embodiment shown, the lighting device 1 comprises a diffuser 5 serving as a luminous body, a substantially non-transparent mirror 7, and a partially transmissive mirror 9 formed on the inner side of the cover plate 8. The diffuser 5 is aligned substantially plane-parallel to the housing base or to the support plate 4 and is fixed to an inner edge of the housing 3 at a distance from the light sources 2. The non-transparent mirror 7 is embedded in the diffuser 5. In particular, the diffuser 5 has a recess on the side facing away from the light sources 2, in which the non-transmissive mirror 7 is received.

[0025] On the side facing away from the light sources 2, the non-transparent mirror 7 has a mirror surface or reflective surface. The partially transparent mirror 9 is arranged downstream of the non-transparent mirror 7. The partially transparent mirror 9 is designed as a two-way mirror film or Venetian mirror film, with the cover plate 8 acting as the carrier for the mirror film. In this exemplary embodiment, a clear polycarbonate carrier is used as the carrier. A pictogram 6b is engraved or stamped on the inside of the front mask 6. The front mask 6 completes the entire structure and can be specifically designed as a visible part in the vehicle.

[0026] A film 8a is applied to the side edges or outer edge of the cover plate 8 or the polycarbonate carrier to prevent unwanted light coupling or reflections at the edges of the cover plate 8. In some embodiments, the outer edge of the cover plate 8 is painted to prevent reflections at the outer edge.

[0027] In the cross-sectional view of the Fig. 2 also shows the adjustment mechanism for adjusting the end plate 8 or the semi-transparent mirror 9. The adjustment mechanism comprises a linear guide 10 and a piston rod 11 received in the linear guide 10. The linear guide 10 is fixedly mounted at one end on the carrier plate 4 or circuit board, whereby the piston rod 11 can be moved along the linear guide 10. At an end free from the linear guide 10, the piston rod 11 has a joint socket 11a of a ball joint 12 with a joint head 13 received therein. The joint head 13 has a fastening projection which projects through a central round material recess in the end plate 8 and is fixedly connected to the adjustment lever 14. The joint head 13 is mechanically connected to the piston rod 11 by means of a joint nut 13a, so that the joint head 13 can rotate in the joint socket 11a. The ball joint 12 orThe joint head 13 and adjustment lever 14 can, for example, be screwed together, thus connecting the end plate or the polycarbonate carrier with the central round material recess or central opening to the adjustment mechanism. Due to the linear guidance of the ball joint, the adjustment mechanism allows both translational and rotational degrees of freedom.

[0028] The adjustment mechanism of the lighting device 1 can be operated manually. The operation of the adjustment lever 14 is Fig. 2 is illustrated in the bottom left of the figure. The adjustment lever 14 is operated with one hand 18.

[0029] By operating the adjusting lever 14, the piston rod 11, including the joint socket and ball joint 12, can be moved along the linear guide 10 or in the axial direction. The ball joint 12 enables a rotational or tilting movement of the adjusting lever 14 or the end plate 8.

[0030] In the Fig. In the state shown in Figure 2, the cover plate 8 is in a central position and is aligned parallel to the non-transparent mirror 7. In this state of the lighting device 1, the mirror arrangement forms a plane-parallel double mirror arrangement, resulting in a series of coaxial, spaced-apart images of the lighting structure.

[0031] Fig. 3 shows a schematic cross section of the lighting device according to Fig. 1 in a second state. In the Fig. In the state shown in Figure 3, the adjustment lever 14 is pulled out to the stop. The double mirror arrangement 7, 9 has the maximum possible distance between the mirrors 7 and 9, while maintaining the plane-parallel geometry of the double mirror arrangement 7, 9. This also results in a series of coaxial images, with the images being spaced further apart.

[0032] Fig. 4 shows a schematic cross section of the lighting device according to Fig. 1 in a third state. In the Fig. In the state shown in Figure 4, the adjustment lever 14 is pushed in as far as it will go, so that the distance between the mirrors 7 and 9 is reduced to a minimum distance. Here, too, the double-mirror arrangement 7, 9 retains its plane-parallel geometry. The resulting images exhibit a coaxial arrangement, with the distance between the images reduced to the minimum distance.

[0033] Fig. 5 shows a schematic cross section of the lighting device according to Fig. 1 in a fourth state. In the Fig. 5, the axial position of the ball joint 12 corresponds to that shown in Fig. 2. In contrast to the position shown in Fig. In the state shown in Figure 2, the adjusting lever 14 or the end plate 8 is tilted downward. This state can be determined in particular from the first state, cf. Fig. 2, can be achieved by pressing the adjustment lever 14 downwards by hand, see illustration below left in Fig. 5. Due to the inclination of the cover plate 8 or the semi-transparent mirror 9, the gap between mirrors 7 and 9 has a downwardly tapered shape. This results in a series of laterally shifted images, with deeper images appearing more strongly shifted downward.

[0034] Fig. 6 shows a schematic cross section of the lighting device according to Fig. 1 in a fifth state. The fifth state essentially corresponds to the one in Fig. 5, wherein the adjusting lever 14 is tilted upwards. This state can be reached, for example, from the first or fourth state by pushing the adjusting lever 14 upwards by hand, see the figure below left in Fig. 6. Such an adjustment of the adjusting lever 14 or the end plate 8 leads analogously to the Fig. 5, a lateral displacement of images occurs, with lower-lying images appearing to be shifted more upwards.

[0035] Depending on the inclination of the adjustment lever 14, images can be shifted in different lateral directions, with lower-lying images appearing more strongly shifted in this direction. This results in a particularly attractive spatial distortion or curvature effect, which can be perceived as particularly pleasant by viewers and vehicle occupants.

[0036] Fig. Figure 7 shows schematically the lighting device according to Fig. 1 in an exploded view and Fig. 8 and Fig. 9 show schematically the lighting device according to Fig. 1 in different exploded views. In the exploded view of the Fig. 7 and in the exploded views of the Fig. 8 and Fig. 9, the arrangement of individual components of the lighting device 1, from the bottom of the housing 3 to the end plate 8 or the front mask 6, is particularly clearly visible. Fig. 7, Fig. 8 and Fig. 9 clearly shows that the lighting device 1 can be assembled in a simple manner. For example, in a first step, the base of the housing 3 can be prepared, onto which the carrier plate 4 equipped with LEDs as light sources 2 can be mounted. The carrier plate 4 can be equipped with a mounting element, in particular an SMD (Surface Mounted Device) element, for mounting the linear guide 10.

[0037] In a subsequent step, the side wall of the housing 3, equipped with the diffuser 5 and the opaque mirror 7, optionally together with the linear guide 10, can be placed on the bottom of the housing 3. The piston rod 11 with the joint socket 11a can be inserted into the linear guide 10. The joint head 13 can then be inserted into the joint socket 11a and fixed to the joint socket 11a with the joint nut 13a. After the joint head 13 is fixed to the joint socket 11a, the end plate 8 together with the mirror 9 or mirror film can be placed onto the mounting boss of the joint head 13 so that the mounting boss protrudes through the central opening of the end plate 8. The adjusting lever 14 can then be firmly connected to the mounting boss of the joint head 13. The joint head 13 and the adjusting lever 14 can be connected to each other in a force-locking and / or form-locking manner, e.g.are screwed together, thus connecting the polycarbonate carrier with a central, round material recess to the movable system. In a final step, the front mask 6 with the light trap 6a can be placed on the housing 3. The front mask 6 can also function as a fixing element or stop for the cover plate 8 or for the semi-transparent mirror 9, so that when the adjustment lever 14 is pulled out, the cover plate 8 or the adjustment mechanism does not fall out of the lighting device 1.

[0038] During operation of the lighting device 1, light is generated by light sources 2 to illuminate the diffuser 5. Due to the spaced arrangement of the diffuser 5 from the light sources 2, the individual light cones generated by the light sources 2 illuminate the diffuser 5 over a wide area. In addition, any light rays reflected from the side walls of the housing 3 can also fall on the diffuser 5 and contribute to illuminating the diffuser 5. Due to the diffuse properties of the diffuser 5, the incident light spreads out inside the diffuser 5 and creates a diffuse glow of the diffuser 5. The light can emerge, among other things, from the side of the diffuser 5 facing away from the light sources 2, specifically from the areas not covered by the non-transparent mirror 7.

[0039] In the illustrated embodiment, an edge region of the diffuser 5 in the form of an octagonal frame is not covered by the non-transparent mirror 7. From this region, the light can thus exit the diffuser 5 and enter the space between the non-transparent mirror 7 and the partially transparent mirror 9. At least a portion of the light incident on the partially transparent mirror 9 can pass through the partially transparent mirror 9 and through the cover plate 5 to the outside. Thus, the diffuser 5 can be visually perceived from the outside as a luminous structure or as a luminous frame.

[0040] A portion of the light incident on the partially transmissive mirror 9 can be reflected back by the mirror and redirected by the non-transmissive mirror 7 onto the partially reflected mirror 9. A portion of this light can pass through the partially transmissive mirror 9 and through the cover plate 8 to the outside. In this way, images of second, third, and higher orders can be created, which are visually perceptible from the outside. Multiple reflections between the mirrors create a multitude of repetitions of the light graphic or luminous structure with decreasing luminance within the housing or in the inner housing channel. These images can appear spatially offset from one another, particularly according to the laws of geometric optics, which can lead to an infinity or volume effect.

[0041] In some embodiments, the inner walls of the housing 3 are designed to be substantially white or highly reflective in some regions, particularly in the area between the support plate 4 and the diffuser 5. The support plate 4 can also have a substantially white or highly reflective surface. This can increase the overall luminous efficacy of the lighting device 1.

[0042] In some embodiments, the inner walls of the housing 3 are black or light-absorbing in some areas, particularly in the area between the non-transparent mirror 7 and the partially transmissive mirror 9. This allows stray light or background light to be suppressed or reduced, in particular to optically emphasize the images of the diffuser.

[0043] Fig. 10 shows schematically a perspective view of the lighting device according to Fig. 1 in operation. Fig. Figure 10 shows simulation results and illustrates the infinity or volume effect that can be achieved by means of the lighting device 1 at three different positions of the adjustment lever 14. The corresponding positions of the adjustment lever 14 are shown in the upper part of the Fig. 10. The three positions of the adjustment lever 14 correspond to the Fig. 2, Fig. 3 and Fig. 4 shown states of the lighting device 1. On the left in the picture a state of the lighting device 1 is shown in which the adjusting lever 14 or the connecting plate 8 is pushed in as far as it will go, cf. Fig. 4 above. In the center of the image, a state of the lighting device 1 is shown in which the adjusting lever 14 or the connecting plate 8 is in the center position, cf. Fig. 2 above. The right side of the image shows a state of the lighting device 1 in which the adjusting lever 14 is pulled out to the stop, cf. Fig. 3 above. In all three positions, the adjusting lever 14 is aligned along the guide 10 or the piston rod 11, so that the mirror arrangement 7,9 maintains a plane-parallel geometry.

[0044] In the view shown, the lighting device 1 has three different illumination states 15, 16, 17, wherein images of the diffuser 6 are visible in the form of octagonal rings arranged one behind the other at different depths. If the lighting device 1 is used as an interior lighting device of a vehicle, the lighting device 1 can be viewed by vehicle occupants from different perspectives. When the eye positions of the vehicle occupants change, the position of the images changes, but the arrangement of the images relative to one another remains unchanged due to the laws of geometric optics. This creates the illusion for the observer that the lighting device 1 has an infinite depth and that an infinite number of luminous rings are arranged one behind the other inside the lighting device 1. Due to the plane-parallel alignment of the double mirror arrangement in the Fig. The illumination states 15, 16, 17 of the lighting device 1 shown in Figure 10 are the Fig. arranged coaxially one behind the other.

[0045] If the adjusting lever 14 is now tilted in a lateral direction or sideways, the cover plate 8 and the partially transparent mirror 9 connected to it tilt. The mirrors 7 and 9 are thus no longer parallel, but are aligned at an angle of inclination corresponding to the inclination of the adjusting lever 14. The inclination of the mirrors 7 and 9 relative to each other leads to a change in the arrangement or spatial position of the images. In particular, the inclination of the adjusting lever 14 leads to a series of laterally shifted images, with deeper images appearing to be shifted more strongly in the direction of the inclination of the adjusting lever 14, cf. explanations on Fig. 5 and Fig. 6 above.

[0046] It should be noted that the lighting device 1 offers interior designers considerable design freedom. All components can be implemented in various variants. The housing 3 can also have a different polygonal shape. Furthermore, the optical properties of the diffuser 6, the semi-transparent mirror 9, and the cover plate 9 can be varied. For example, the transparency of the semi-transparent mirror 9 can be reduced, particularly to increase the relative brightness of higher-degree images. For example, with a transparency of 50%, a smooth brightness gradation can be achieved between images of different degrees with a relatively high overall luminous efficacy. The transmittance and / or diffusivity of the cover plate 8 can also be used as parameters in the design of the lighting device 1.For example, an inscription, for example in the form of a structured film, can be provided on the outer side of the cover plate 8. The inscription on the cover plate 8 as well as the pictogram 6b or the logo on the inner wall of the front mask 6 are intended, in particular, to emphasize the design possibilities of the lighting device 1. The cover plate 8 with high transmission or a clear pane as the cover plate 8, particularly with a high transparency of the semi-transparent mirror 9, could be used, for example, to make the inscription on the cover plate 8 appear as if it were floating in space.

[0047] By adjusting the position or inclination of the cover plate 8, the user or vehicle occupant can specifically adjust the repeating images or light patterns according to their individual preferences. This allows for any number of individual lighting states to be realized. In addition to the states shown in the figures above, the adjustment lever 14 can have any number of intermediate positions or different inclination angles.

[0048] The lighting device 1 described here is characterized by a particularly compact and cost-effective construction and, in addition to the variable volume and infinity effects, offers considerable design freedom. Due to the axial arrangement of the light sources, a significant increase in the luminance of the luminous structure or light graphic can be achieved. This enables an increase in perceptibility in bright environments with the same number of LEDs or a reduction in the number of LEDs while maintaining constant luminance. Furthermore, a more homogeneous luminance distribution can be achieved within each repetition of the light pattern in the axial direction. The representation of the light pattern thus appears more precise and improves the perceived quality, particularly compared to the state of the art. Furthermore, the complexity of the assembly is reduced, among other things, by positioning the LEDs on a common plane.This allows the carrier plate or board to be designed as a solid body, so that a design of the board with varying surface normals can be avoided.

[0049] In the exemplary example of the lighting device 1 shown, the movable components are moved mechanically by the viewer's hand 18, without the need for additional electrical components. Thus, the desired light pattern display can be adjusted directly and intuitively by the viewer by operating the adjustment lever 14. Furthermore, electrification of the adjustment mechanism with actuation by additionally attached switches or drives would also be conceivable, which should not be excluded from the exemplary mechanical representation.

[0050] By choosing a mechanical solution, costs such as additional motors and their energy consumption, as well as the operational noise of the electric drives, can be avoided. Electrical control of the adjustment mechanism, on the other hand, would allow greater freedom in the design of the visible areas of the lighting arrangement, as well as automated lighting animations.

[0051] Although at least one exemplary embodiment has been shown in the foregoing description, various changes and modifications may be made. The recited embodiments are merely examples and are not intended to limit the scope, applicability, or configuration of the present disclosure in any way. Rather, the foregoing description provides those skilled in the art with a road map for implementing at least one exemplary embodiment; numerous changes may be made in the function and arrangement of elements described in an exemplary embodiment without departing from the scope of the appended claims and their legal equivalents. Furthermore, multiple modules or multiple products may be connected together in accordance with the principles described herein to obtain additional functions.
