    Description: The present invention relates to a lighting arrangement with which linearly arranged point-shaped light sources can be generated for illumination purposes. In particular, the illumination arrangement according to the invention has a laser as the light source and represents a fully integrated optical solution.
    Various variants of Beleuchtungsan¬ordnungen are already known from the prior art, which use a laser as the light source. All these lighting arrangements have a free-beam optics. In this case, the light of the laser is typically deflected by means of a microelectromechanical system (MEMS) chip, which in the simplest case is an adjustable mirror, and output from the illumination arrangement. The advantage of a laser as a light source is the higher efficiency and that the light of the laser can be transported better in waveguides than, for example, the light of classical LEDs. Another advantage of a laser as a light source is that a more dynamic illumination of areas is possible.
    However, the disadvantage of the illumination arrangements known from the prior art, in particular of the MEMS solutions, is that free-field optics have a high sensitivity to environmental influences, such as, for example, water vapor on the surfaces of the mirrors. Furthermore, such free-beam optics can not be integrated and are extremely sensitive to alignment inaccuracies between laser and mirror, for example caused by vibrations. Furthermore, the illumination arrangements known from the prior art are very complicated to manufacture and operate due to the free-field optics, in particular with regard to a necessary exact alignment between laser and mirror. Insbeson¬dere mirrors are also mechanically very sensitive and can be easily damaged. Another disadvantage of the known MEMS solutions is that only the light distribution, i. H. the position is given to the light, but not the light intensity is changeable.
    Starting from the known from the prior art lighting arrangements, in particular MEMS solutions, it is therefore an object of the present invention, at least to reduce the disadvantages described above, at best to eliminate. In particular, it is an object of the present invention to provide a lighting arrangement with a laser as a light source which is more compact, reliable and independent of environmental influences than the prior art. Another object of the present invention is to provide an integrated optical solution for such a lighting arrangement. It is a requirement of the lighting arrangement that an exact alignment of the components of the lighting arrangement is relatively simple. A further requirement is that the lighting arrangement is not only very compact, but in particular can also be integrated as a flat unit. Finally, the lighting arrangement should make it possible to change the distribution as well as the intensity of the light.
    The objects described above are achieved by a lighting arrangement according to independent claim 1. The dependent claims further advantageously form the essence of the invention in order to meet further requirements.
    The present invention relates to a lighting arrangement comprising an elongated main waveguide, one or more distributed to the main waveguide and vor¬zugsweise at least partially arranged transversely to this auxiliary waveguide, at least one laser, which is adapted to light in at least one End of the main waveguide einzuloppeln, and one or more decoupling units, which are adapted to couple light from the main waveguide in the auxiliary waveguide.
    The illumination arrangement represents an integrated optical solution with a laser as the light source. All the advantages of a laser as a light source over, for example, an LED, i. Higher efficiency and more dynamic illumination are used by the present invention without the disadvantages of a free-beam optics to be accepted.
    For example, the illumination arrangement according to the invention is less sensitive to environmental influences than the prior art. Since no mirrors are used, as in arrangements known from the prior art, the illumination arrangement according to the invention is also less sensitive to adjustment inaccuracies, vibrations and shocks. Even an exact alignment between the laser and the mirror is eliminated, i. The present invention is easier to manufacture and operate. Finally, the illumination arrangement can be designed to be smaller, in particular significantly flatter, than illumination arrangements known from the prior art.
    Advantageously, the decoupling units are ring resonators.
    Advantageously, the ring resonators are arranged to the outer circumference of Hauptwel¬lenleiters and designed such that light from the main waveguide can couple into the ring resonators.
    In particular, the ring resonators fulfill a specific resonance condition which enables light extraction from the main waveguide. The distance to the main waveguide and the radius of the ring resonators are chosen accordingly. The underlying principle of light extraction is based on a kind of tunnel effect, which is known from the field of signal transmission and not intrinsically core component of the invention. Thus, punctiform light sources of the illumination arrangement along the preferably elongated main waveguide are arranged by the ring resonators, preferably at regular intervals.
    Advantageously, the ring resonators are so angeord¬net to the secondary waveguides that light from the ring resonators can couple into the auxiliary waveguide.
    By the same effect as described above, light passing through or localized in a ring resonator is transmitted through a kind of tunneling effect into a sub-waveguide associated with the ring resonator, and ultimately output from the end-face of the sub waveguide facing away from the illumination arrangement. The distance of the ring resonators to the correspondingly assigned secondary waveguides is chosen accordingly.
    According to another advantageous variant, the coupling-out units are end portions of the auxiliary waveguides facing the main waveguide, which are curved in such a way that they extend at least partially close enough to the main waveguide to allow the light to be coupled from the main waveguide into the auxiliary waveguide.
    The auxiliary waveguides can be curved in such a way that they run at least partially parallel to the main waveguide. The principle of light decoupling for this embodiment is the same as the principle for the embodiment with ring resonators. Due to a small distance between the main waveguide and the end section, light can be transmitted by a kind of tunnel effect when the end section is suitably formed. However, for this embodiment, there is no need to provide a ring resonator formed separately from the auxiliary waveguide, which simplifies production of the illumination arrangement.
    Advantageously, the decoupling units are end portions of the sub-waveguides, which are approximately rectangular in cross-section and adjacent to the main waveguide.
    Each approximately rectangular end region used in this embodiment is a so-called multimode interference coupler (MMI coupler). Due to the direct adjacency of the end regions to the main waveguide, main waveguides, auxiliary waveguides and Auskoppeleinlein units can be integrally formed.
    Advantageously, the decoupling units consist of a material whose Brech¬zahl is variable.
    By changing the refractive index of the decoupling units, the proportion of the light to be coupled out at these points can be determined. For example, the Resonanzbedin¬gung a ring resonator by changing the refractive index of the material of the ring resonator changeable. The decoupling units can, for example, be changed together. Preferably, the decoupling units can be individually modified with regard to their refractive index. Thus, it can be set individually how much light is emitted from which point-shaped light source of the illumination arrangement. Thus, with the illumination arrangement according to the invention, it is possible to achieve a linear arrangement of punctiform light sources, the intensity of each being individually adjustable. As a result, it can be set, for example, which area (s) is illuminated by the illumination arrangement and even with what intensity the individual area element (s) are / are illuminated.
    Advantageously, the refractive index of the material is variable when the material is exposed to an electromagnetic and / or thermal field and / or light.
    The material is thus changeable, for example by means of electromagnetic radiation, by a magnetic field and / or with heat in its refractive index. Thus, with easily controllable parameters, the amount of coupled-out light can be influenced specifically and individually for each decoupling unit.
    Advantageously, the lighting arrangement comprises at least one element for generating an electromagnetic and / or thermal field and / or light.
    Thus, the illumination arrangement thus has an integrated control for modifying the decoupling areas and thus for changing the light intensities of the decoupling units.
    Advantageously, an element for generating an electromagnetic and / or thermal field and / or light is arranged on one or both sides of each decoupling unit.
    This ensures a particularly effective control of each decoupling unit individually.
    Advantageously, the refractive index of the material is changeable when the material is illuminated, and at least one element for illuminating the decoupling units is provided.
    Thus, the decoupling units are thus controllable by means of an opto-optical effect. For example, the actuation can be realized with a generated control light signal and / or even by means of ambient light. This embodiment promises a particularly rapid change in the refractive index of the material of the decoupling unit (s) and thus an illumination arrangement for which the point-light intensity can be adjusted particularly quickly and extremely selectively.
    Advantageously, the main waveguide is branched into a plurality of parallel waveguides, each of the parallel waveguides being provided with a plurality of coupling-out units.
    As a result, a lighting arrangement with areal or matrix-like light output can be produced.
    Advantageously, a plurality of lasers, in particular lasers of different colors, are provided for preferably simultaneous coupling of light into the main waveguide.
    In such an embodiment of the illumination arrangement according to the invention, it may further be influenced which light color is most efficiently decoupled from the main waveguide. The light color and / or the light color temperature of each ejection unit, ie each point light source of the illumination arrangement, can thus be set individually. It can also be simply a mixed-colored, eg white light generated. For this purpose, for example, three decoupling units can be arranged close to each other and thus combined to form a group or unit. The decoupling units of the group are then controlled so that each decoupling unit emits red, blue or green light, respectively, to produce a total white light. The intensity and / or light color temperature of the white light thus generated is easily and quickly adjustable.
    The three decoupling units of such a group can also be assigned together to a Nebenwel¬lenleiter.
    Advantageously, at least the Auskoppeleinheiten facing Endberei¬che the auxiliary waveguide of a material whose refractive index is changeable when it is exposed to an electromagnetic and / or thermal field and / or light.
    Thereby, further, the intensity of the total light output from each dot-shaped light source of the lighting device can be adjusted. In particular, in conjunction with lasers of different colors, it is thus possible to set individually and selectively the color of the coupled-out light and simultaneously the intensity of the light for each point-like light source. For example, on the one hand, this is influenced by a change in the refractive index of a decoupling unit influence on the color of the coupled-out light, while the adjustment or change in the refractive index of the associated sub-waveguide influence on the intensity of the decoupled light is taken.
    Advantageously, each auxiliary waveguide is assigned an element for generating an electromagnetic field and / or thermal field and / or light.
    It is particularly advantageous to combine these elements associated with the secondary waveguides with further elements which are assigned to the coupling-out units in order to enable an integrated activation for light color or color temperature as well as light intensity.
    The present invention will now be described in detail with reference to the accompanying drawings.
    FIG. 1 shows a first embodiment of a lighting arrangement of the present invention; FIG. 2 shows a second embodiment of a lighting arrangement of the present invention; FIG. 3 shows a third embodiment of a lighting arrangement of the present invention.
    The basic principle of the present invention is based on providing a waveguide which is preferably elongated and in whose at least one end light is coupled by means of at least one laser. Furthermore, one or more decoupling units are provided, preferably at regular intervals, on the elongated waveguide, which decouple the light into one or more relatively short secondary waveguides arranged transversely to the main waveguide. Light is then emitted via the end faces of these secondary waveguides facing away from the main waveguide.
    FIG. 1 shows a first embodiment of the present invention. The lighting arrangement 1 has the main waveguide 2, which is preferably elongated in shape. The longitudinal main waveguide 2 can also branch in its extension direction into a plurality of, preferably parallel, main waveguide branches, in order to form an elongated, surface-area or matrix-type main waveguide 2. The main waveguide 2 or each main waveguide branch can also bend or curve and is shown in FIG. 1 as an example only. The main waveguide may also be annular.
    In a first end of the main waveguide 2 (or at a certain point of a ring-shaped main waveguide 2) by means of a laser 4 light is coupled into the main waveguide 2. It is also possible to feed light from different lasers into one end of the main waveguide 2. It is also possible to couple light from several lasers into both ends of the main waveguide 2. The laser 4 shown in Figure 1 could also be integrated into the main waveguide 2, for example, be cast into it. As a result, the lighting arrangement 1 according to the invention could be rendered even more robust, compact and efficient, since in this case no losses can occur when the laser light is coupled into the main waveguide 2. Furthermore, outcoupling losses from the laser diode itself could also be reduced, since a reduced refractive index difference between main waveguide 2 and laser 4 would result. Advantageously, the light of the laser can also first be converted by a phosphor and / or quantum dot structures in order to eliminate the detrimental effect of the speckling. Speckling can occur due to the coherent laser light.
    Along the main waveguide 2, are generally designated, coupling-out units 5a, 5b, 5c provided. The decoupling units 5a, 5b, 5c are preferably arranged at regular intervals relative to one another or in regularly arranged groups near adjacent decoupling units. In FIG. 1, the decoupling units are designed as ring resonators 5a. Light is coupled out of the main waveguide 2 via these ring resonators 5a and in turn is coupled in auxiliary waveguides 3, which are perpendicular to the main waveguide 2, and output from their front side. For improved output from the front faces of the sub-waveguides 3, corresponding optical elements may still be provided to influence the light output, for example filters, lenses, grids, diaphragms or the like. In particular, conversion means can also be provided on the end faces of the auxiliary waveguides 3, which are suitable for converting the light into a different light suitable for the desired illumination. In this case, for example, a secondary-emitted light can be emitted by a conversion means excited by the light. The conversion medium preferably alters the wavelength of at least part of the light. One or more conversion means may be used to generate white light output from the illumination assembly 1 of the present invention.
    The ring resonators 5a shown in FIG. 1 act as optical output couplers. The ring resonators 5a are located on the outer circumference of the main waveguide 2 and on the other hand in the vicinity of the sub-waveguides 3. The effect of coupling the laser light from the main waveguide 2 into the ring resonators 5a is comparable to the tunneling effect known from quantum mechanics. Specifically, the ring resonators are arranged and formed to the outer periphery of the main waveguide 2 so that light from the main waveguide 2 can tunnel into the ring resonators 5a. In particular, the distance of the ring resonators 5a to the main waveguide 2 and the circumference or radius of the ring resonators 5a must be selected accordingly. The distance and radius of the ring resonators 5a may be selected depending on the wavelength of the laser light. The resonance conditions of the ring resonators 5a are preferably chosen such that the laser light with maximum efficiency i. maximum light intensity coupled into the ring resonators 5a.
    In the same way, then the light running along in the ring resonators 5a, which is located in these quantum mechanical, is coupled into the corresponding associated auxiliary waveguide 3. Due to the recurring arrangement of ring resonators 5a and associated sub-waveguides 3, light can be coupled out at the desired locations along the main waveguide 2.
    Preferably, the resonance conditions of the ring resonators 5a can be selectively changed, preferably individually changed for each ring resonator 5a. By such a change, the proportion of the light to be coupled out at this point of the main waveguide 2 can be adjusted at least in terms of the light intensity. Such an adjustment not only makes it possible to determine which area is illuminated by the illumination arrangement 1 according to the invention, that is to say from which ring resonators 5a light is actually coupled out, but also with what intensity the light is coupled out of the respective ring resonators 5a. The resonance conditions may be changed, for example, by changing the radii of the ring resonators 5a or the material of the ring resonators 5a.
    The present invention preferably proposes to make the ring resonators 5a of a specific material whose refractive index can be changed. For example, the change in the refractive index can be achieved by a thermo-optical, electro-optical, magneto-optical and / or opto-optical effect. For example, special materials may be used that change their refractive index depending on whether they are exposed to an electric field, a magnetic field, a light field or a thermal field. These effects are very pronounced, for example, in polymers, which is why polymers are available as material for the ring resonators 5a, at least for regions to be changed.
    Preferably, the lighting arrangement 1 comprises at least one element 6 for generating an electric field, magnetic field, electromagnetic field, thermal field or a light beam. For example, field-generating elements 6 can be provided on each side of each ring resonator 5a for driving via an electromagnetic field. By means of these adjusting elements 6 can then be adjusted by changing the refractive index of the material of the ring resonators 5a, how much light is coupled out by each entspre¬chenden ring resonator 5a and transmits in the associated sub-waveguide 3. Such an adjustment element 6 can be provided for the entire illumination arrangement 1. However, an individual element 6 can also be provided for each ring resonator 5 a, so that the setting of the material refractive index for each ring resonator 5 a can be carried out individually. Thus, a linear arrangement of point light sources along the main waveguide 2, the intensity of each of which can be set individually, can be achieved.
    Of course, one or more of such elements 6 may also be present for applying approximately one thermal field to the ring resonators 5a or to each ring resonator 5a. By adjusting the heat of the material of the ring resonators 5a, its coupling-out efficiency is then set. As another example, a lighting element 6 may also illuminate and thereby drive a ring resonator 5a or a plurality of ring resonators 5 simultaneously or individually with a light signal. The light impinging on a ring resonator 5a changes its refractive index with a suitable choice of material, so that the coupling-out efficiency also changes.
    FIG. 2 shows a second embodiment of the illumination arrangement 1 of the present invention. The elements provided with the same reference numerals as in Figure 1 are identical as described above for the first embodiment. The difference between the embodiments is merely that in the second embodiment, the Auskoppeleinlein 5a, 5b, 5c are formed differently. Instead of the ring resonators 5a of the first embodiment, end sections 5b of the auxiliary waveguides 3 now act as the coupling-out units 5a, 5b, 5c. In particular, for this purpose, each auxiliary waveguide 3 is bent or curved at its end section facing the main shaft guide 2 in such a way that the end section 5b extends almost parallel and close to the main waveguide 2. By a correspondingly close arrangement of the end sections 5b of the auxiliary waveguide 3 to the main waveguide 2, light can decouple from the main waveguide 2 again.
    Again, an individual setting of the coupling-out efficiency from the main waveguide 2 into each auxiliary waveguide 3 can be achieved by forming at least the end sections 5 of the secondary waveguides 3 located close to the main waveguide 2 of a material which is characterized by a suitable field as described above can be controlled to change and adjust the refractive index.
    FIG. 3 shows a third embodiment of the illumination arrangement 1 of the present invention. The lighting arrangement 1 of the embodiment of Figure 3 is in turn similar to the lighting arrangements 1 of the previously described embodiments. The only difference is that instead of ring resonators 5a in the first embodiment or curved end sections 5b of the auxiliary waveguide 3 in the second exemplary embodiment, so-called multimode interference couplers are now used as the coupling-out units 5a, 5b, 5c. The multimode interference couplers are in particular rectangular Endbe¬reiche 5c of the auxiliary waveguide 3, each having a cross-sectionally approximately rectangular shape and each immediately adjacent to the main waveguide 2. The multimode interference coupler can thus be part of the main waveguide 2.
    Again, at least these rectangular end portions 5c are made of a material so that they are changeable in terms of their refractive index by means of a suitable field as described above. Again, the efficiency of decoupling from each decoupling unit can be controlled by setting a desired refractive index through the appropriate material and appropriately positioned adjustment elements 6.
    For all described embodiments of the illumination arrangement 1, it is possible that not only a single laser 4 is used for coupling light into the main waveguide 2, but that instead a plurality of lasers 4 are used. It is particularly preferable to use lasers 4 that emit or emit light in different colors, for example red, green and blue. By a corresponding adjustment of the refractive indices of the individual decoupling units 5a, 5b, 5c (as described above), it is now possible to influence which color is most efficiently decoupled from the main waveguide 2. In this case, it would therefore be possible to set for the individual auxiliary waveguides 3 which light, in particular of which color, is to be coupled out of the main waveguide 2 in which outcoupling units 5a, 5b, 5c. For this purpose, all the different colored lasers 4 are preferably coupled into the main waveguide 2 simultaneously.
    As a further development of the illumination arrangement 1 according to the invention, it is conceivable that both the color of the light coupled out from the main waveguide 2 and the intensity of the light emitted by the auxiliary waveguide 3 can be adjusted. For this purpose, parts of the auxiliary waveguides 3 can likewise be made of a material whose refractive index can be adjusted by an identical or different field. The auxiliary waveguides 3 can also be completely formed from such a material. For example, Figure 1 shows how adjusters 6 can be arranged adjacent to the sub-waveguides 3 to vary at least the refractive index of their end regions. By appropriately setting the refractive index of these end regions, the efficiency of the coupling out of the light from the coupling-out unit 5 a, 5 b, 5 c in FIG. 1, in particular the ring resonator 5 a, can be changed or adjusted into the auxiliary waveguide 3. In this way, not only the color but also the intensity of the light emitted via the auxiliary waveguides 3 can thus be changed.
    Preferably, both the decoupling units 5a, 5b, 5c and the respectively associated sub-waveguide 3 are made of a refractive index variable material and corresponding adjusting elements 6 are provided on each auxiliary waveguide 3 and on each decoupling unit 5a, 5b, 5c. Advantageously, the decoupling units 5a, 5b, 5c are made of a different refractive index variable material than the associated Nebenbenleiter 3. In particular, the difference in the materials that unterschiedli¬che fields must be used to change the refractive index. Correspondingly, separate adjustment elements are provided in addition to turn-off units 5a, 5b, 5c and secondary waveguides. As an example, the materials of the coupling-out units 5a, 5b, 5c can be changed by their refractive index by heat, and the materials of the auxiliary waveguides 3 can be changed in their refractive index by electrical and / or magnetic fields. This guarantees a separately executable control even with small distances. Other examples are possible. It is also possible to provide such material differences between individual decoupling units 5a, 5b, 5c and / or individual auxiliary waveguides 3 in order to control different point-shaped light sources of the illumination arrangement 1 in a targeted manner separated from one another.
    In summary, the present invention describes an integrated optical solution for a lighting arrangement 1 with a laser 4 as the light source. The laser 4 couples light into a preferably elongated main waveguide 2. The laser light can be coupled into a plurality of outcoupling units 5a, 5b, 5c in a plurality of secondary waveguides 3 arranged transversely to the main waveguide 2. The coupling-out units 5a, 5b, 5c may be ring resonators 5a, curved end regions 5b (couplers) of the auxiliary waveguides 3 or adjacent end regions 5c (multimode interference couplers) of the auxiliary waveguides 3.
    The lighting arrangement 1 of the present invention can replace a free-beam optic of the prior art and is therefore more compact, reliable and more independent of environmental influences. In addition, by changing, for example, the resonance conditions of the ring resonators 5a or, in general, the refractive index of the coupling-out units 5a, 5b, 5c of the portion of the light determined from the point-shaped light sources of the illumination arrangement 1 determined by the coupling-out units 5a, 5b, 5c , is decoupled.
