Description

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

[0002] Lighting arrangements for vehicle interiors are known. Lighting arrangements with LEDs (light-emitting diodes) as light sources are also known. These lighting arrangements can be designed to illuminate vehicle interiors and / or as decorative or accent lights. In particular, lighting arrangements for generating luminous structures are known. Such lighting arrangements generally have a complex structure and little flexibility in the representation of luminous structures.

[0003] An object of the embodiments of the present disclosure is to provide a visually appealing lighting arrangement with a small installation space, high luminous efficacy and high flexibility in the representation of luminous structures.

[0004] To achieve this object, a first aspect provides a lighting arrangement for the interior of a vehicle. The lighting arrangement comprises a housing, a luminous element for generating a luminous structure within the housing, and at least one light source for illuminating the luminous element. In particular, the at least one light source can comprise one or more illuminants and be configured to illuminate the luminous element by illuminating the luminous element.

[0005] The lighting arrangement further comprises a mirror arrangement for creating an appearance of the lighting arrangement in which the luminous structure appears multiple times at different depth levels within the housing. The appearance of the luminous structure at different depth levels can create not only a volume effect but also a visual infinity effect, in particular an illusion of infinitely repeating structures.

[0006] The lighting arrangement also comprises at least one electro-optical element arranged in the beam path of the lighting arrangement with controllable optical properties for modifying the appearance of the lighting arrangement.

[0007] In particular, the at least one electro-optical element can comprise an optical body with variable optical properties, the optical properties of which can be modified by applying an electrical voltage or an electric field. The possibility of modifying the appearance of the lighting arrangement by means of the at least one electro-optical element can, in particular, expand the lighting design options of the lighting arrangement.

[0008] In some embodiments, the at least one electro-optical element is configured to be switched between a substantially diffusely translucent and / or opaque state and a substantially transparent state by applying a voltage or by applying current. With the electro-optical element in the diffusely transparent state in the beam path of the illumination arrangement, the infinity effect based on specular reflections can, in particular, be suppressed, attenuated, or converted into a diffuse glow with a luminance that increases radially outward.

[0009] The mirror arrangement can comprise a substantially non-transparent or opaque mirror with a mirror surface facing away from the at least one light source. In particular, the mirror arrangement can be designed such that the light emitted by the luminous element and reflected back within the mirror arrangement is reflected back forward by the mirror surface facing away from the light source. The resulting multiple reflections can lead to an enhancement of the visual effect of the repeating structures. The non-transparent mirror can rest against the luminous element with a side facing the at least one light source. 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, wherein 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 luminous structure.

[0010] The mirror arrangement can further comprise at least one partially transparent mirror arranged downstream of the substantially non-transparent mirror. The at least one partially transparent mirror can, in particular, have a specific degree of transparency. In particular, the partially transparent mirror can be designed such that a specific portion of the light incident on the partially transparent mirror is transmitted. A specific 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.

[0011] 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 arrangement. 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.

[0012] 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, in particular 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 arrangement. The support of the partially transparent mirror can simultaneously function as a cover plate or as a light exit window of the lighting arrangement.

[0013] 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 arrangement.

[0014] The at least one electro-optical element can be arranged, in particular, within the mirror arrangement. By arranging the at least one electro-optical element within the mirror arrangement, in particular between the non-transparent mirror and the partially transmissive mirror, light recycling can be actively influenced. In particular, the diffusivity or the proportion of diffusely scattered light in the space between the non-transparent and partially transmissive mirror can be controlled by controlling the at least one electro-optical element.

[0015] In some embodiments, the at least one electro-optical element is arranged downstream of the mirror arrangement. In particular, the illumination arrangement can comprise at least one electro-optical element arranged downstream of the partially translucent mirror. In the diffusely translucent state, the electro-optical element can thus serve as a diffuse cover or privacy screen, in particular to shield the interior structure of the illumination arrangement.

[0016] In some embodiments, the lighting arrangement comprises a cover plate, in particular provided with lettering or a pictogram, wherein the lighting arrangement can further comprise an electro-optical element arranged downstream of the cover plate. In particular, the electro-optical element can be arranged such that, in the diffusely light-scattering state, it can conceal the lettering or the pictogram on the cover plate in the unlit state of the lighting arrangement. In some embodiments, the at least one electro-optical element is designed or positioned such that the lettering on the cover plate has a higher contrast in the diffusely light-scattering state of the electro-optical element than in the transparent state of the electro-optical element. By setting the electro-optical element to the basic state, the lettering can thus be specifically highlighted.

[0017] In some embodiments, the lighting arrangement comprises a mirror optics system upstream of the luminous element, wherein the mirror optics system is designed to direct the light generated by the at least one light source to the luminous element in a targeted manner. In particular, the mirror optics system can be designed as an optical booster for the targeted illumination of one or more areas of the luminous element. Due to the targeted illumination of the luminous element, the luminous brightness of the luminous structure can be significantly increased, so that a target brightness can be achieved with less electrical power or with fewer LEDs.

[0018] The mirror optics can comprise at least one light guide channel for guiding the light generated by the at least one light source to the luminous element. By means of the light channels, in particular, the light generated by the at least one light source can be channeled such that it reaches the luminous element with essentially no or minimal light loss. In particular, the mirror optics can comprise mirror surfaces that are essentially directed towards one another. The mirror surfaces that are essentially directed towards one another can, in particular, form a light channel in the form of a cavity in which the light can be guided to the luminous element in a particularly efficient manner, in particular by reflections or multiple reflections at the mirror surfaces.In particular, the mirror optics can be designed such that at least one hollow space is created between the two mirror surfaces, which tapers in the axial direction to the defined size of the diffuser area to be illuminated, so that the illumination of the diffuser or the luminous element is essentially limited to specific areas of the luminous element. By limiting the illumination to specific areas of the luminous element, a particularly pronounced luminous structure can be created.

[0019] The housing can comprise a substantially axially symmetrical side wall and a flat housing base, wherein the at least one light source can be arranged substantially planarly on an inner side of the flat housing base. In particular, the light source can comprise a carrier plate or circuit board arranged planarly on the flat housing base, with a number of LEDs distributed over the surface of the circuit board. The luminous element and the second mirror arrangement can be arranged downstream of the at least one light source and the mirror optics in the axial direction and can be designed substantially plane-parallel to the housing base. Due to the planar structure of the light source on the housing base, the structure of the lighting arrangement can be simplified overall and the overall dimensions of the lighting device, in particular in the radial direction, can be reduced.

[0020] According to a second aspect, a vehicle is proposed. The vehicle has at least one interior with at least one lighting arrangement according to the first aspect for the lighting design of the interior of the vehicle. Due to the targeted illumination of the luminous element, the brightness of the luminous structure can be increased, so that a clearly perceptible glow for vehicle occupants can be achieved even in high ambient brightness.

[0021] 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 a perspective exploded view of a lighting arrangement according to an embodiment, Fig. 2 shows an exploded perspective view of a lighting arrangement according to another embodiment, Fig. 3 shows a perspective exploded view of a lighting arrangement according to a further embodiment, Fig. 4 shows a perspective view of a lighting arrangement according to an embodiment in operation, and Fig. 5 shows a perspective view of a lighting arrangement according to Fig. 3 in a switched off state.

[0022] Fig. 1 shows a perspective exploded view of a lighting arrangement according to an embodiment. From the exploded view of the Fig. 1 the arrangement of individual components or the structure of the lighting arrangement 1 can be seen particularly well.

[0023] The lighting arrangement 1 comprises a number of light sources 2 and a housing 3. The lighting arrangement 1 further comprises a carrier plate 4 or carrier board, on which the light sources 2 are arranged in a circle. In the illustrated embodiment, LED light sources or LEDs are used as the light sources.

[0024] The housing 3 has a substantially octagonal, flat bottom. The support plate 4 also has a substantially octagonal shape and is aligned substantially parallel to the bottom of the housing 3.

[0025] The lighting arrangement 1 also includes a luminous element 5 or diffuser. In this exemplary embodiment, the luminous element 5 is essentially flat and also has a substantially octagonal shape, with the luminous element having a peripheral edge of increased thickness.

[0026] In the illustrated embodiment, the lighting arrangement 1 comprises a front mask 6, a non-transparent mirror 7, and a cover plate 8 with a partially transparent mirror 9 and lettering 10. In the illustrated embodiment, the front mask 6 is designed in the form of a tube with an octagonal cross-section and, when viewed from the side, has an upwardly tapered profile. A pictogram 13 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.

[0027] In the exemplary embodiment shown, the lighting arrangement 1 comprises a mirror optics 11 having a radial mirror arrangement which is arranged upstream of the luminous element 5. The mirror optics 11 is designed, in particular, between the carrier plate 4 and the diffuser 5 or luminous element in such a way that the light generated by the light sources 3 can pass through the mirror optics 11 to the luminous element, whereby certain areas of the luminous element can be illuminated more brightly than other areas. The mirror optics 11 functions, in particular, as an optical booster which is designed such that the light generated by the lighting means 2 is directed mainly to the edge areas of the luminous element 5. In this way, the edge areas of the luminous element 5 can be illuminated more brightly than other areas, for example in the middle of the luminous element 5. With an optical booster, a pronounced orA visually clearly perceptible luminous structure can be created.

[0028] In the illustrated embodiment, the non-transparent mirror 7 is embedded in the diffuser 5. In particular, the diffuser 6 has an octagonal recess on a side facing away from the illuminants 3, into which the likewise octagonally shaped non-transparent mirror 7 is received. On the side facing away from the illuminants 3 or toward the partially transparent mirror 9, the non-transparent mirror 7 has a mirror surface or reflective surface.

[0029] The partially transparent mirror is designed in the form of a two-way mirror film 9 or a Venetian mirror film, with the cover plate 8 acting as the carrier of the mirror film. A structured film can be formed on the outer side of the cover plate 9 to form the lettering or inscription 10. In this embodiment, a clear polycarbonate carrier is used as the cover plate 9 or carrier of the partially transparent mirror.

[0030] The lighting arrangement 1 further comprises an electrically controllable optical element or electro-optical element 12, which in the embodiment of the Fig. 1 is arranged between the non-transparent mirror 7 and the partially transparent mirror 9.

[0031] The electrically controllable optical element 12 is designed in the form of a pane with controllable or switchable optical properties. The controllable optical element 12 can, in particular, comprise a switchable privacy film, coating, and / or glass. In some embodiments, the at least one electro-optical element comprises a liquid crystal-based switchable pane with a polymer liquid crystal film embedded between two flat glass panes. In a ground state, for example when no voltage is applied to the liquid crystal film, the liquid crystal film has essentially randomly aligned liquid crystal molecules that essentially diffusely scatter incident light. When an electrical voltage is applied, the liquid crystal molecules can arrange themselves in the electric field such that the glass becomes transparent.

[0032] The possibility of electrically controlling or switching the electro-optical element 12 is described in Fig. 1 symbolically represented by an electrical switch, electrical leads and plus-minus signs.

[0033] In the embodiment shown, the electro-optical element 12 is designed such that it can be reproducibly switched electrically, in particular by applying a corresponding electrical voltage, between a substantially transparent state and a substantially diffuse or diffusely light-scattering state.

[0034] Fig. Figure 2 shows a perspective exploded view of a lighting arrangement according to another embodiment. The embodiment according to Fig. 2 essentially corresponds to the embodiment of the Fig. 1 and has all components of the embodiment according to Fig. 1 on.

[0035] The difference between the two embodiments is essentially in the order of arrangement of optical components. In particular, the electro-optical element 12 is located in the embodiment of the Fig. 2 relative to the light exit direction of the lighting arrangement 1 after the end plate 8, in particular directly after the end bar 8. In the embodiment shown, the lettering 10 is applied directly to the electro-optical element 10.

[0036] Fig. 3 shows a perspective exploded view of a lighting arrangement according to another embodiment. The embodiment according to Fig. 3 essentially corresponds to the embodiments of the Fig. 1 and Fig. 2 and has all components of the embodiments according to Fig. 1 and Fig. 2 on.

[0037] In contrast to the examples of the Fig. 1 and Fig. 2, the electro-optical element 12 is arranged behind the cover plate 8 provided with the lettering 10, with respect to the light exit direction of the lighting arrangement 1.

[0038] From the exploded views of the Fig. 1, Fig. 2 and Fig. 3 it is particularly clear that the lighting arrangement 1 can be assembled in a simple manner.

[0039] For example, in a first step, the base of the housing 3 can be provided, onto which the carrier plate 4 equipped with LEDs as light sources 2 can be arranged or mounted. In a further step, the side wall of the housing 3 can be provided and equipped with the diffuser 5 and the non-transparent mirror 7. The mirror optics 11 or the radial mirror arrangement with an inner mirror and an outer mirror formed essentially coaxially to the inner mirror can then be inserted into the housing 3. In some embodiments, the mirror optics 11 or the optical booster can first be placed on the carrier plate 4 and then introduced into the housing 3.

[0040] The end plate 8 with the semi-transparent mirror 9 can be placed on the front side of the side wall of the housing 2. In a final step, the front mask 6 can be placed on the housing 2. The front mask 6 can also function as a fixing element for securing the end plate 8 or the semi-transparent mirror 9.

[0041] In some embodiments, the partially transparent mirror 9 is formed in the form of a thin coating on the inside of the cover plate 8. In some embodiments, the inside of the cover plate 8 has no coating, so that the cover plate or the uncoated inside of the cover plate 8 can function as a partially transparent mirror with correspondingly low reflectivity or high transparency.

[0042] During operation of the lighting arrangement 1, light or primary light is generated by lamps 2 to illuminate the luminous element 5 or diffuser and is fed into the mirror optics 11 or into the light channel created by the radial mirror arrangement of the mirror optics 11. The light fed into the light channel is guided to the diffuser 5 so that certain areas, particularly at the exit of the light channel, can be specifically illuminated. Due to the diffuse properties of the diffuser 5, the incident light spreads inside the diffuser 5 and creates a diffuse glow from the diffuser 5. The diffuser 5 emits a diffuse secondary light, with the specifically illuminated areas of the diffuser shining particularly brightly. These more intensely illuminated areas of the diffuser can then be more easily perceived visually from the outside, directly or indirectly, depending on the design.By means of the mirror optics 11, the visual perceptibility of luminous structures can be significantly improved.

[0043] In the exemplary embodiment of the lighting arrangement 1 shown here, the primary light is guided by the optical booster to an edge region of the diffuser 5 in the form of an octagonal frame. This edge region of the diffuser 5 is not covered by the non-transparent mirror 7 on the side facing away from the lighting means 2. From this region, the light can thus emerge from the diffuser 5 and be visually perceived. The light emerging from the diffuser 5 can reach 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 8 to the outside. The diffuser 5 can thus be visually perceived from the outside as a luminous structure or as a luminous frame.

[0044] A portion of the light incident on the partially transparent mirror 9 can be reflected back by the mirror and redirected by the non-transparent mirror 7 onto the partially reflected mirror 9. A portion of this light can in turn pass through the partially transparent mirror 9 and through the cover plate 8 to the outside. In this way, images of the second, third, and higher orders can be created, which are visually perceptible from the outside. Multiple reflections between the mirrors thus create a multitude of repetitions of the light graphic or luminous structure with decreasing luminance within 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.

[0045] If the lighting arrangement 1 is used as an interior lighting device of a vehicle, the lighting arrangement 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 coaxial arrangement of the images remains intact due to the laws of geometric optics. This creates the illusion for the observer that the lighting arrangement 1 has an infinite depth and that an infinite number of luminous rings are arranged one behind the other inside the lighting arrangement 1.

[0046] In some embodiments, the inner walls of the housing 2 are black or light-absorbing, at least in some areas, particularly in the area between the non-transparent mirror 7 and the partially transmissive mirror 9. This allows the scattered light or background light to be suppressed or reduced, in particular to visually emphasize the images of the diffuser 5.

[0047] Fig. Figure 4 shows a perspective view of an illumination arrangement according to an embodiment during operation. The right side of the image shows an operating state of the illumination arrangement 1 in which the electro-optical element 12 is in a substantially diffuse light-scattering state. The electro-optical element 12 can be in a basic state in which no voltage is applied to the electro-optical element, which is symbolically represented by an electrical switch in the top right of the image.

[0048] The left side of the image shows an operating state or illumination state of the illumination arrangement 1, in which the electro-optical element 12 is in a substantially transparent state. In some embodiments, this state of the electro-optical element is achieved by applying a voltage to the electro-optical element, which is symbolically represented by an electrical switch in the top left of the image.

[0049] As can be seen from the two illustrations of the Fig. As can be seen in Figure 4, the appearance of the illumination arrangement 1 can be significantly influenced by switching the electro-optical element between these states. In particular, in one illumination state (left in the image), a pronounced infinity effect with repeating luminous rings or ring-shaped images of the diffuser 5 can be seen, while in another illumination state (right in the image), the infinity effect is essentially completely suppressed, switched off, or converted into a diffuse glow with luminance increasing radially outward.

[0050] Fig. 5 shows a perspective view of a lighting arrangement according to Fig. 3 in a switched-off state. In particular, Fig. 5 the lighting arrangement 1 in an unlit state in which the light sources 2 are not energized. No voltage is applied to the optoelectronic element 12, which is symbolically represented by an electrical switch at the top of the image. The electro-optical element 12 is in the basic state or in the diffuse light-scattering state. In this state, the luminous surface or the cover plate of the lighting arrangement 1 appears as a diffuse or milky surface and shields the internal structure of the lighting arrangement 1 from external views. If the light sources 2 are now energized or the electro-optical element 12 is supplied with an operating voltage, the lighting arrangement 1 can be switched to one of the Fig. 4 shown states similar to the state.

[0051] It should be noted that the lighting devices described here offer interior designers considerable design freedom. All components can be implemented in various variants. The housing 3 can also have a different shape, possibly polygonal or round. Furthermore, the optical properties of the diffuser 5, the semi-transparent mirror 9, and the cover plate 8, as well as the position of the electro-optical element 12, can be varied. For example, the transparency of the semi-transparent mirror 9 can be reduced, in particular 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 arrangement 1.The lettering or inscription 10 on the cover plate 8 as well as the pictogram 13 or the logo on the inner wall of the front mask 6 are intended, in particular, to underline the design possibilities of the lighting arrangement 1. The cover plate 8 with a high transmission or a clear pane as the cover plate 8, particularly with a high transparency of the semi-transparent mirror 9, could, for example, be used to make the inscription 10 appear to be floating in space.

[0052] The mirror optics 11 can also be designed differently, in particular specifically adapted to design requirements. For example, the mirror surfaces of the mirror arrangement with radial mirrors can have different angles of inclination. The mirror surfaces of the radial mirrors can, for example, be designed essentially parallel to one another. In some embodiments, the mirror optics 11 is designed such that the light channel widens on the output side. This can, in particular, increase the structural width of the luminous structure and increase the overall luminous efficacy of the lighting arrangement. It is also conceivable for the mirror optics 11 to have mounting elements, in particular mounting pins and / or hooks, with which the optical booster can be mounted on the carrier plate 4, if necessary, on corresponding counter-mounting elements.The optical booster can be manufactured in particular using an injection molding process and provided with mirror surfaces in a coating step.

[0053] The lighting devices described here are characterized by a particularly compact and cost-effective design and, in addition to the clearly visible light structures with pronounced volume or infinity effects, offer considerable design freedom. Due to the axial arrangement of the light sources and the boost effect, a significant increase in the luminance of the light structure or light graphic can be achieved. Compared to the state of the art, 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 impression, 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 circuit board to be designed as a solid body, thus avoiding the need for a circuit board with varying surface normals.

[0054] By controlling the electro-optical element 12 or the switchable layer, very different illumination states of the illumination arrangement 1 can be realized. It is also conceivable that the electro-optical element 12 is controlled to assume an intermediate state, in particular between the transparent and diffuse states, or is gradually transitioned from one state to the other.

[0055] It is also conceivable to place the lettering 10 behind (from the viewpoint of the observer) the electro-optical element 12 or behind the switchable layer in order to be able to conceal it when the electro-optical element 12 is not subjected to a voltage.

[0056] If the electro-optical element suddenly becomes transparent, for example by applying a voltage, the viewer can experience a surprise effect in which a whole series of repeating structures suddenly reveals themselves behind the cover.

[0057] It is also conceivable to use one or more additional controllable or switchable elements in order to vary the degree of diffuse scattering by individually or combined control of these elements and thus expand the variety of possible lighting states.

[0058] 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.
