    elements
    The invention relates to an illumination device for a motor vehicle having at least one illumination shaping unit comprising a light source and an additional optical unit, as well as to an optically active component connected downstream of the illumination shaping unit in the optical beam direction.
    The use of luminescent materials in automobiles and headlamps (e.g., fluorescent or phosphorescent phosphor panels, license plate lighting, designer shutter lighting, etc.) to achieve specific lighting and design effects is well known.
    DE 102012018292 A1 discloses a motor vehicle in which one or more component surfaces visible from outside the motor vehicle are designed as fluorescent and / or phosphorescent luminous surfaces. The phosphorescent or fluorescent substances are either applied to the component surfaces or embedded in the component.

    DE 102004045221 A1 discloses a lighting device for a license plate, in which the illumination of the license plate takes place with the aid of fluorescent light generated by fluorescent substances.
    EP 1577609 B1 discloses a vehicle headlamp with a signal device with a phosphor coating, wherein the surfaces of a light guide plate are provided with a fluorescent lacquer.
    DE 2361569 A1 discloses very generally the use of fluorescent, phosphorescent and reflective substances as an admixture to an injection-moldable plastic material in order to thus produce signal and warning means as marking or marking of vehicles.
    It is an object of the invention to provide a lighting device with special lighting effects; In particular, it is an object of the invention to provide a lighting device in which the visual appearance after deactivating the actual light function is still consistent (styling effect, afterglow) and with the additional homogenization of the light emission is achieved.
    This object is achieved by a lighting device as mentioned at the outset, which is inventively characterized in that the light source or the additional optical unit comprise at least partially pigments of at least one luminescent material, and that the optically active component homogenizes the light exit.
    In contrast to the cited prior art, in the invention the luminescent element, i. the light source or the additional optical unit, a part in the interior of the illumination device, which is separated from the outside by the optically acting component and therefore is not directly visible from the outside. Because of this, the visual appearance is still consistent thanks to the invention after deactivating the light function. In other words, the appearance of afterglowing follows that of the actual light function of the illumination device, e.g. Signal light (daytime running or parking light) or dipped beam. The emitted (luminescent) light is further shaped or scattered via the optically active component or via the additional optical unit, for which reason additionally an additional homogenization of the exiting (luminescence) light is achieved.
    In contrast, in the above-mentioned prior art, the appearance in the activated and deactivated state of the light function is different or not homogeneous, because the luminescent material is not part of an optical element (light source such as a light guide or an LED, additional optical unit such as a reflector) and / or directly visible to an outside observer.
    According to the invention, a predetermined light signature should be homogeneously illuminated and provided with a striking styling effect.
    The term "optically effective component which homogenizes the light emission" refers to a component which homogenizes the light emission in such a way that, when the light source is activated or when the light is emitted by the luminescent pigments after deactivation of the light source, an area of the component located behind the component Lighting device is not directly visible, ie the direct view of the area behind the component is denied.The "optically active component", as described in more detail below, for example, be an imaging lens, an intermediate lens or a thick-walled optics; however, it may also be composed of several components (e.g., a multiple lens system) which cooperatively perform the light homogenizing function. The optically effective component also acts as a light-shaping device to correctly display the required lighting function and to ensure the spatial visibility of lighting functions.
    In order to display the afterglow effect on the basis of the light function of the illumination device (for example a signal light function), according to the invention the light source or the additional optical unit are at least partially provided with pigments of at least one luminescent material. The luminescent material is suitably selected from a fluorescent material or a phosphorescent material. The terms "luminescence / luminescent", "phosphorescence / phosphorescent" and "fluorescence / fluorescent" and their functional principle, namely the emission of optical radiation in the transition from an excited state back to the ground state, are assumed to be notoriously well known the phosphorescence is a special form of luminescence, whereby the fluorescence decays rapidly, whereas the phosphorescence fades for a longer time .. Representative examples of luminescent / phosphorescent materials are the pigments 50101 (green, for high luminance), 50105 (grin, low luminance but very low) Pigment size) and 50034 (blue) from Honeywell.
    The term "the pigments of the at least one luminescent material have a signal effect" as used herein means that the luminescence or afterglow appearance after deactivating the light function of the illumination device follows that of the light function (eg signal light, dipped beam), ie Preferably, the appearance of the lighting device is substantially the same for an outside viewer when the light function is on and off, depending on the choice of pigments and their amount, as will be apparent to those skilled in the art based on their knowledge, skill and simple routine experimentation is able to select appropriate pigments or luminescent materials and to measure the quantity thereof The light distribution of illumination devices (eg a signal light such as a limiting light or a daytime running light, dipped beam) is usually regulated by law These requirements are notoriously well-known to those skilled in the art.
    Further, by the choice of the luminescent material (also referred to herein as luminophore or phosphor), the color of the luminescence can be adjusted according to the position on the motor vehicle and different color impressions can thereby be generated. The color range depends on the light function and is subject to legal requirements, e.g. the currently valid ECE or SAE regulations. Direction indicators have a signal light function and, according to currently valid specifications, must be in the yellow range, irrespective of whether they are on the vehicle front, on the rear of the vehicle or as a side marker lamp, for example. attached to the exterior mirror. Taillights, brake lights, rear fog lights and rear parking lights are in the red zone, while daytime running lights, front side or side clearance lights and front parking lights are in the white range according to current regulations. The blue range is intended for emergency vehicles. As mentioned, the selection of suitable luminophores is within the knowledge of a person skilled in the art.
    In certain embodiments, the pigments may comprise two or more different luminescent materials. For example, the respective materials may have a different excitation spectrum. For example, one material can be excited by light in the visible wavelength range and another material by light in the non-visible wavelength range for the emission of luminescence (fluorescence, phosphorescence). For example, with a blue light emitting LED or a blue light emitting laser, a reddish phosphor can be targeted and a bluish phosphor can be excited by a UV LED.
    In certain embodiments, the light source is designed as a light guide or as an LED and the additional optical unit is designed as a reflector with a light-reflecting surface, wherein the light guide or the reflector at least partially comprise pigments of at least one luminescent material. The pigments of the at least one luminescent material advantageously have a signaling effect.
    It has proved in these embodiments in practice to be advantageous if the optically active component is an intermediate lens or a thick-walled optics. The construction, the configuration and the arrangement of an intermediate lens or a thick-walled optics are carried out according to well-known to those skilled in the art principles.
    The attenuation of the light function (e.g., daytime driving or tailing light) is achieved in certain variants by means of a light guide. The optical waveguide is typically rod-shaped with a light-incoupling surface on one end face and a light-emitting surface radiating transversely to the longitudinal axis. The light exit is achieved by a plurality of deflection prisms, which are arranged opposite the light exit surface on the lateral surface of the light guide and follow the longitudinal axis direction. Behind the light guide, a reflector is also arranged, which captures light which emerges from the back of the light guide by means of its light-reflecting surface and beneficially deflects it to the front (i.e., in the optical beam direction).
    In one embodiment, the pigments of the at least one luminescent material in the form of a luminescent layer are applied at least in regions to the light-reflecting surface of the reflector. Preferably, the entire light-reflecting surface of the reflector is coated with the pigments.
    In a further embodiment, the pigments of the at least one luminescent material are at least partially embedded in the reflector. In this case, the reflector can be doped with the pigments already during production; e.g. For example, the reflector may be made of a pigment-doped plastic material.
    In yet another embodiment, the pigments of the at least one luminescent material are at least partially embedded in the light guide. In this case, the light guide can be doped with the pigments already during production; e.g. For example, the optical fiber may be made of a pigment-doped photoconductive plastic material such as e.g. PMMA or polycarbonate.
    The excitation / activation of the pigments for the emission of luminescence can take place in a further development by the light coupled into the optical waveguide by a first light source and emitted by the optical waveguide, i. the excitation is effected by the light when the lighting function of the illumination device is activated.
    In a further variant, the excitation / activation of the pigments to emit luminescence can be actively effected by additional light sources. The illumination device can therefore have at least one further light component which excites the pigments to emit luminescence. The light component may comprise at least one light source for visible light and / or at least one light source for non-visible light, in particular UV light. The light source can be for example an LED, but also a laser. In a sub-variant, the light component comprises at least one light source for visible light and at least one light source for non-visible light, in particular UV light. Advantageously, the at least one light component is positioned on the light guide. Preferably, it is positioned on at least one end face of the light guide. As the afterglow effect on luminescent substances decreases over time, in a specific example it may be expedient to keep the afterglow effect for longer than naturally given by means of active illumination by the additional light source with non-visible light and to maintain it in a controlled manner over time. The invention can also be used when switching on for special lighting effects. For example, when opening the motor vehicle by means of a remote control, first the light source for the non-visible light is activated, which excites the luminescent layer of the illumination device to emit luminescence and thus leads to glowing; a little later, the lighting device (e.g., daytime running light, tailing light) is then dimmed with the actual light function (e.g., glow stick, reflector).
    The reflector preferably has light-homogenizing structures on its light-reflecting surface, preferably groove-like structures around which
    Inhomogeneity of the light guide or the LED to conceal. In order to further homogenize the luminance or to increase the luminous area, an optically active component is connected downstream of the optical waveguide / LED in the optical beam direction as described above.
    In a further embodiment of the illumination device, the illumination shaping unit is designed as a collimator optics, wherein the additional optical unit has a collimator, the collimator (primary optics) at least partially comprising pigments of at least one luminescent material. Illuminators based on collimator optics and their structural design are well known to those skilled in the art. The optically active component is expediently an imaging lens (secondary optics) in this embodiment. In further developments, the imaging lens can be provided in a manner known per se with additional means which enhance the homogenization of the light exit, for example with microstructures.
    The pigments are preferably applied or embedded in deflection edge regions of the collimator. The Umlenkflankenbereiche are located on the rear surface of the collimator. The pigments are therefore applied in a variant on the rear surface of the collimator, where the Umlenkflankenbereiche are located as a surface layer. In the other variant, the pigments may be embedded locally in the Umlenkflankenbereiche.
    The applied or embedded pigments of the at least one luminescent material advantageously have a signaling effect.
    Expediently, the light emitted by the illumination device according to the invention forms the light distribution of a signal light, in particular a daytime running light or a boundary light or a direction indicator, or a low beam and / or high beam, wherein the light distribution of the respective lights as mentioned above subject to legal requirements, which are known in the art ,
    A further subject matter of the invention is a motor vehicle headlight comprising at least one illumination device according to the invention as disclosed herein. Modern motor vehicle headlights often have a plurality of light modules, which can take on their own or in cooperation individual light functions. These light modules are often arranged in close proximity to each other in a spotlight housing.
    Conveniently, the motor vehicle headlamp is constructed according to known headlamp design principles and comprises a housing with a light exit opening, which is covered with a cover plate, wherein the at least one at least one illumination device (and possibly the other provided light modules) are arranged in the housing. If the illumination device according to the invention is a signal light, it may, for example, be designed or arranged such that it follows the lens aperture of a light module or specific design lines.
    The motor vehicle headlight may for example have the shape of a headlight. The construction of a headlight is known to the person skilled in the art. Headlamps often include multiple light modules, e.g. a daytime running light unit, a low beam unit, a high beam unit, a turn signal unit, etc. Accordingly, the respective light modules of the headlamp can form the light distribution of a daytime running light, a low beam, a high beam, a turn signal, etc. An inventive headlight therefore also comprises at least one illumination device according to the invention, in addition to the light modules known per se. The motor vehicle headlight may be a taillight in another example. The construction of a tail light is known to the skilled person. Tail lights often include multiple light modules, e.g. a tail lamp unit, a stop lamp unit, a turn signal unit, etc. Accordingly, the respective light modules of the taillight can form the light distribution of a tail lamp, a brake light, a turn signal, and so forth. A rear light according to the invention therefore comprises, in addition to the light modules known per se, at least one illumination device according to the invention.
    The invention will be further described by way of non-limitative examples and accompanying drawings, in which:

    Fig. 6b shows the section of Fig. 6a with a detailed view of the luminescence.
    Fig. 1 shows a section through a lighting device according to the invention, here a signal light 1 for a motor vehicle. The signal light 1 comprises a substantially rod-shaped light guide 20 and a reflector 10 arranged behind the light guide 20. The light-reflecting surface of the reflector 10 is covered with a luminescent layer 12. The luminescent layer 12 is composed of pigments of a luminescent material (or else several luminescent materials). In the example shown are pigments of a phosphorescent material. However, the layer 12 can also be composed of fluorescent pigments or of a mixture of several different luminescent (fluorescent and / or phosphorescent) materials / pigments. The signal light 1 also has a downstream of the light guide 20 in the optical beam direction
    Lens 30 on. The intermediate lens 30 is designed according to known principles and acts light-shaping, ensures the spatial visibility of signal light functions, homogenizes the luminance and prevents direct insight from the outside to the underlying components (light guide 20, reflector 10). The intermediate lens 30 may be clear or "milky".
    The light exit from the light guide 20 is achieved by a plurality of deflection prisms 21, which are arranged opposite the light exit surface on the lateral surface of the light guide 20 and follow the longitudinal axis direction (see also Fig. 3). The reflector 10 directs the light, which emerges from the back of the light guide 20, by means of its light-reflecting surface beneficial forward. The light emission cone 25 directed forward in the beam direction out of the light guide 20 and the light emission cone 24 out of the light guide 20 toward the rear in the direction of the reflector 10 are shown schematically in FIG. The light 24 from the light guide 20 represented by the light emission cone 24 excites the luminescent pigment layer 12 to emit luminescent light 15 (shown schematically by arrows 15).
    The signal light 1 is arranged in a motor vehicle headlight, which is constructed according to known headlight construction principles and comprises a housing with a light exit opening, which is covered with a lens cover. In Fig. 1, only the lens 50 is shown schematically. The motor vehicle headlight has, in addition to the signal light after per se known type still one or more light modules.
    2 shows a section through a further lighting device according to the invention, here a signal light 2. The construction of the signal light 2 corresponds to the structure of the signal light of FIG. 1, with the only difference that instead of an intermediate lens 30, a thick-wall optical system 40 connected downstream in the optical beam direction having. The light 25 emitted by the light guide 20 is shaped and homogenized by the thick-wall optical system 40. The thick-walled optical system 40 is also designed according to known principles and acts light-shaping, ensures the spatial visibility of signal light functions, homogenizes the luminance and prevents direct insight from the outside to the underlying components (light guide 20, reflector 10). With respect to all other components of the signal light 2 (i.e., light guide 20, reflector 10, luminescent layer 12, etc.), reference is made to the above description of the signal light 1 (Figure 1).
    In Fig. 3 the luminous impression of the signal light 1 of Fig. 1 in front view and without intermediate lens 30 is shown. The light source 22, e.g. A light produced by a 450nm laser diode or InGaN (Indium Gallium Nitride) LEDs enters an end face 26 of the substantially rod-shaped and a design line-following optical fiber 20. The color emission of the light source 22 is matched to the corresponding signal light function. If the light source 22 is designed as a laser diode, then in order to make the laser light usable for a motor vehicle illumination device, the laser light irradiates a luminous element, a so-called phosphor converter, which is thereby excited to emit visible light; The phosphor converter is tuned to the desired color of the signal light function. For this purpose, various materials are known or in use. InGaN LEDs are available in blue, yellow, red or UV, for example. The light exit from the light guide 20 is achieved by a plurality of deflecting prisms 21 ', which are arranged opposite the light exit surface on the lateral surface of the light guide 20 and follow the longitudinal axis direction (dashes 21' symbolize the translucent, ie visible from the front, edges of the Umlenkprisms 21st ). The light 24 emerging from the light guide 20 and striking the back of the reflector 10 as described above impinges on the luminescent layer 12 of phosphorescent pigments, whereby the pigments are excited to emit luminescence 15 (phosphorescence). The reflector 10 also has light-homogenizing groove-shaped structures 13 on its light-reflecting surface, which conceal the inhomogeneity of the light guide 20.
    4 shows an alternative embodiment of the invention in which the luminescent pigments 11 are not applied to the reflector as a luminescent layer, as shown in the other figures, but are embedded in the light guide 20, which has a plurality of deflection prisms 21 as described. For this purpose, the light guide 20 is already doped during production with the luminescent pigments 11; e.g. For example, the optical fiber 20 may be made of a pigment-doped photoconductive plastic material, such as e.g. PMMA or polycarbonate. As shown in FIG. 2, the optical waveguide 20 is followed by a thick-wall optical system 40 in the optical beam direction of the light emerging from the signal light. At or in the immediate vicinity of an end face of the light guide 20 are
    Light sources 22 and 23 arranged. The light source 22 as primary light source is, for example, a 450 nm laser diode or indium gallium nitride (InGaN) LEDs whose color emission is matched to the corresponding signal light function. The light sources 23 may be, for example, UV LEDs or 405 nm laser diodes (visible light in the blue wavelength range). Are the light source 22 and the light sources 23 formed as a laser diode, then, to make the laser light for a car lighting device usable, while the laser light a luminous element, a so-called. Phosphor converter, irradiated, thereby characterized for the emission of visible Light is excited; The phosphor converter is tuned to the desired color of the signal function. For this purpose, various materials are known or in use. InGaN LEDs are available in blue, yellow, red or UV, for example. In this Ausftihrungsform the excitation / activation of the luminescent pigments 11, alternatively or in addition to the light source 22, by the light sources 23. By active illumination by the additional light sources with non-visible UV light, for example, the Nachglimmeffekt longer than natural and temporally controlled maintained become. When the signal light is switched on, this variant can also be used for special lighting effects. For example, when the motor vehicle is opened by means of a remote control, first the light source 23 for the non-visible UV light or for the blue 405 nm light is activated, which excites the embedded pigments 11 to emit luminescence and thus leads to a glow; A little later, the signal light (daytime running light, limiting light) with the actual light function is then dimmed by switching on the light source 22 for visible light. In advantageous developments, the embedded pigments 11 may comprise two or more different luminescent materials. For example, the respective materials may have a different excitation spectrum. For example, a first material can be excited by the light source 22, which emits light in the visible wavelength range, and another material by the light sources 23, which can emit light in the non-visible wavelength range (eg UV), for the emission of luminescence (fluorescence, phosphorescence) become.
    FIG. 5a shows a section through FIG. 3 along the line AA with a detailed view with regard to the excitation of the luminescent layer 12 arranged on the reflector 10 through the light 24 emitted from the light guide 20 towards the reflector 10 (see also FIG Description for Fig. 1 and Fig. 3). The emitted
    Luminescence 15 is directed by means of the reflector 10 in the beam direction of the emerging from the signal light 1 light 25.
    FIG. 5 b shows a section through FIG. 3 along the line A-A with a detailed view with regard to the luminescence 15 emitted by the luminescent layer 12 after the deactivation of the actual signal light function caused by the light guide 20. In the concrete example, as mentioned above, the luminescent layer 12 is composed of pigments of a phosphorescent material. FIG. 5 b therefore illustrates the "afterglow" visible to an outside observer due to the phosphorescence 15 emitted by the layer 12.
    Fig. 6a shows a section through a further embodiment of a
    Illumination device 3 according to the invention with collimator optics, with a detailed view for excitation of the luminescence by the collimator optics. The illumination device 3 comprises, as a primary optic, a collimator optic comprising a light source 22a in the form of a visible light LED and a collimator 60. The collimator 60 is constructed according to known principles and has a feed region 61 for the light emitted by the light source 22a, a light exit surface 63 and deflecting edge regions 62, at which the light is directed forward in the direction of the light exit surface 63, on. The primary radiation after exiting the light from the primary optics (collimator optics) is indicated by reference numeral 66. On the Umlenkflankenbereichen 62 of the collimator 60, a luminescent layer 12 of pigments of a luminescent material (or more luminescent materials) is applied. Alternatively, the pigments may also be embedded locally in the deflecting edge regions 62 (not shown). In the example shown are pigments of a phosphorescent material. However, the layer 12 can also be composed of fluorescent pigments or of a mixture of several different luminescent (fluorescent and / or phosphorescent) materials / pigments. The illumination device 3 further has an imaging lens 65 (secondary optics) connected downstream of the collimator optics (primary optics) in the optical beam direction. The imaging lens 65 prevents the direct view from outside on the area behind it and homogenizes the luminance or the light emission. In further developments, the imaging lens can be provided in a manner known per se with additional means which further enhance the homogenization of the light emission, for example with microstructures. The light distribution of the illumination device 3 is marked with the reference character 66 '. Of course, instead of a single imaging lens 65, a lens system (not shown) may also be used as the secondary optics, which system satisfies the function homogenizing the light exit. The excitation of the luminescent layer 12 for emission of luminescence 15 is effected by the light emitted by the light source 22a and deflected at the deflecting edge regions 62. The emitted luminescence 15 passes through the collimator 60 and the imaging lens 65 to the outside.
    FIG. 6b shows the section from FIG. 6a with a detailed view with regard to the luminescence 15 emitted by the luminescent layer 12 after deactivating the light function caused by the collimator optics (light source 22a, collimator 60). In the concrete example, as mentioned above, the luminescent layer 12 is composed of pigments of a phosphorescent material. FIG. 6 b therefore illustrates the "afterglow" visible to an outside observer due to the phosphorescence 15 emitted by the layer 12.
