    description
    LUMINAIRE OPTICS The following invention relates to a luminaire optics for directional light emission and a luminaire optics system comprising at least two luminaire optics according to the invention and also a luminaire with luminaire optics according to the invention or luminaire optics system according to the invention.
    Different optical elements are known from the prior art in order to provide an optical system with the lowest possible beam divergence, that is to say the smallest possible opening angle and a small amount of scattered light. Areas of application are, for example, spotlights, spots, bicycle lights, headlights and the like.
    [0003] Different attachment optics in different forms are known from the prior art, such as reflectors or TIR lenses 300 (see FIGS. 3c and 4c). Optical systems are also known in which the optical components are arranged one after the other in several stages; see. see, for example, DE 10 2010 039 306 A1. In the spotlight area, in addition to lenses for many applications, apertures for reducing stray light are often used as optical components. The latter, for example, in the area of projectors.
    A special form of light concentrators is also known, for example, from the solar field. So-called CPC concentrators (CPC = Compound Parabolic Concentrator) 200 are used there. Such is shown by way of example in FIG. 2. With reference to FIGS. 3b and 4b, it can be seen that this optics 200 has an uncontrolled direct light component 201, which makes directional light emission more difficult and leads to a comparatively high beam divergence. Furthermore, there are disruptive corona-like rings or images around the central spot (area). Similar effects result from the previously described TIR lenses 300 (cf. FIGS. 3c and 4c).
    It is an object of the present invention to provide an optical system with particularly low beam divergence.
    [0006] This object is achieved by the subject matter of the independent claims. The dependent claims further develop the central idea of the invention in a particularly advantageous manner.
    According to a first aspect, the invention relates to a luminaire optics. This has a first optic and a second optic. The first optic extends from a flat bottom area to a tip. In this case, the first optical system is preferably essentially conical. The side surfaces of the first optics connecting the base region to the tip are preferably rotationally symmetrical, the present invention being not restricted to this. The second optic in turn has an opening into which the first optic protrudes at least with its tip. The second optical system is also designed in such a way that it couples light from the first optical system (preferably into the opening) into the opening and emits it in a directed manner from the second optical system. According to the invention, “coupling in” means that the light enters or is emitted into the corresponding optics (here the second optics). On the one hand, this includes the introduction of light into a full-body optic, but it can also mean the emission of light into a hollow optic (e.g. reflector).
    A crucial aspect of the present invention thus lies in particular in the first optics, which in itself is the subject of the present invention. This first optic is a type of aspherical beam splitter, the surface of which can preferably be described by an inclined conic section rotating about the central axis; alternatively, an arc shape or any spline geometries are also conceivable. In contrast to the known CPC concentrators, in the first optics described here the conic section, as can be seen in FIG. 1, is inclined downwards towards the axis of rotation, see / 17
    AT16 245U1 2019-05-15 Austrian
    Patent office that the surface of rotation ideally tapers. In this way, preferably all light coupled into the first optics can be deflected on the side surfaces of the first optics connecting the bottom regions with the tip; preferably by total reflection on these side surfaces. This deflected light is then decoupled at the counter surfaces and is ready for coupling into the second optics, so that a direct light component - that is, a component of light that is not deflected by the conical section surface shown in FIG. 1 but emerges again directly at the front - is avoided is (see FIG. 3a and in particular FIG. 4a). In the second optics, the entire light can then be influenced or redirected in the desired manner for the directed light emission.
    Also a conventional central lens 302 in conventional TIR auxiliary lenses 302, as shown, for example, in FIGS. 3c and 4c, is omitted, as a result of which possible corona-like phenomena can be controlled significantly and at best can even be eliminated. FIGS. 3c and 4c also show the beam paths of a TIR lens 300, it being shown in FIG. 4c that the (direct) light 301 guided via the central lens can emerge in a problematic manner in an uncontrollable manner, particularly in the case of a relatively large light source for optics and thus directional light emission is difficult.
    The first optics is preferably formed as a solid body and, as already described above, represents in particular a beam splitter. The corresponding light control of the first optics is shown by way of example in FIG. 3a.
    In a preferred embodiment, the bottom region of the first optics has a light coupling surface for coupling light into the first optics or into the lamp optics or the lamp system. The side surfaces of the first optics connecting the base region to the tip are preferably designed such that everything coupled into the base region of the first optics is (totally) reflected on the side surfaces in such a way that it is reflected on the opposite side surfaces of the first optics is extracted from this. As already described above, a direct light component described above can be avoided in this way.
    The focal point of the totally reflecting side surfaces is preferably in the center of the floor area as a light coupling surface. The focal point of the totally reflecting side surfaces is preferably within the first optics or outside the first optics. The focus point is particularly preferably on an axis of rotational symmetry thereof. However, it is also conceivable that it lies away from the axis of rotational symmetry. The light distribution through the first optics works particularly well when the focal point of the totally reflecting side surfaces is in the center of the light entry surface. With corresponding parabolic outer or side surfaces, a particularly high divergence of the beam splitter (= first optics) can be achieved. However, it is also conceivable to provide flat side surfaces. As just mentioned, the first optics can have a parabolic or else an arcuate or other curved outer contour running from the bottom region to the tip. The divergence of the first optic can be varied depending on the outer contour, which can also be flat (that is to say, overall conical).
    The side surfaces of the first optics connecting the base region to the tip can extend in an area near the base surface from the base surface to the tip or cylindrically. In this way, it is possible to provide the first optics in a demoldable manner for manufacturing reasons. In a preferred embodiment, the widening or cylindrically extending region then forms a region for light control or optically ineffective. The light is then to be coupled into the first optics in such a way that as little light (fraction) as possible falls on this ineffective optical area. This can be done, for example, by a defined arrangement of the light source or the illuminant, as will be described below.
    A distance is preferably provided between the tip of the first lens and the area of the second lens delimiting the opening. The light emerges from the first lens and is then guided through the opening to the second lens, where it is switched on accordingly

    Patent office is coupled. Thus, the light optimally or definedly divided by the first optic enters the second optic of the luminaire optic in order to be made available and redirected there for directional light emission. Since there is no direct light component, all of the light coupled into the luminaire optics can consequently preferably be deflected in a correspondingly directed manner and a particularly low beam divergence can thus be achieved.
    The second stage of the luminaire optics, ie the second optics, is now provided in order to deflect the 'fanned out' light in the desired direction by the beam splitter. In the simplest case, classic reflectors are suitable as a second stage in order to redirectly deflect the light coupled out by the first optics. TIR optics or other optics are also conceivable, for example, for more demanding tasks.
    The second optics can consequently also be designed as a solid body, wherein this solid body can be correspondingly connected to a reflector in order to be available in combination with one another for the deflection of the light coupled into the second optic.
    As already mentioned, the second optical system is designed to couple light coupled out of the first optical system into the opening. Fundamentally, it is also conceivable to couple part of the light outside the opening, but with a corresponding coupling in of all light, a particularly efficient light yield is achieved via the opening.
    The second optical system is preferably designed to deflect the light by means of reflection or total reflection for directional light output from the second optical system. A reflection is present in particular when using a normal reflector. When using the appropriate optics, as will be described below (for example TIO optics), a light deflection by means of total reflection is also conceivable and even preferred.
    The second optics can have a shape extending and widening away from the first optics from a side having the opening that receives the first optics. Such a shape is shown for example in FIG. 6. The second optic then preferably forms a frusto-conical shape which is opposite to the first optic and preferably has a flat bottom area in its side facing away from the first optic, which tapers towards the first optic towards a flat end area. In the context of the invention, “flat” generally means that a corresponding geometrical surface can be stretched on a corresponding side at least between the delimiting edge regions thereof, even if the said side has an opening or the like.
    [0020] The forehead region can have the opening that at least partially accommodates the first optics. The opening that at least partially accommodates the first optics can be cylindrical or conical or conical. It is also conceivable that the opening is formed continuously through the second optics.
    According to a preferred embodiment, the flat bottom area of the second optics forms the decoupling surface of the lamp optics.
    The bottom region of the second optics can furthermore have a recess, preferably a central recess, which is particularly preferably provided in a region that is not effective for the light emission. This cutout on the light exit side of the luminaire optics or second optics preferably serves to optimize the volume, so that the optics can be better manufactured using the injection molding process and ultimately manufacturing costs can be saved and weight can be reduced. However, the geometry of the second optics can also be used for a new internal total reflection; this can be followed by a further optic after the second optic. However, it is primarily used for decoupling from the luminaire optics.
    [0023] According to a preferred embodiment, the first optics and the second optics can also be formed integrally with one another. This has particular advantages in terms of manufacturing and assembly, since the optics are already optically optimized in the manufacturing process

    Patent office can be aligned to each other.
    [0024] According to a further aspect, the invention also relates to a luminaire optics system which has at least two luminaire optics according to the invention. The first optics and / or the second optics are connected to one another by means of connecting elements. According to a preferred embodiment, at least two connecting elements are provided, in which case the first connecting element carries or (fix) connects the first optics and the second connecting element the second optics. These can thus be provided separately and brought together in a desired manner to form the luminaire optics system.
    The connecting elements can furthermore have fixing elements in order to connect a plurality of connecting elements to one another. This is particularly so in that a defined positioning of the first optics with the second optics is provided for the targeted and desired directional light emission.
    It is particularly preferred that the connecting elements and optionally also the fixing elements are integrally formed with the respective optics.
    According to a further aspect, the invention further relates to a lamp which has a lamp optics or a lamp optics system according to the present invention. Furthermore, a corresponding luminaire has at least one illuminant for coupling light into the first optics or the luminaire optics or the luminaire optics system.
    The illuminant can preferably be provided at a distance from the first optics, in particular the light coupling surface of the first optics. In this way, for example if there is an air gap between the illuminant and the first optics, the first refraction of the light takes place as soon as the light emerges from the illuminant, so that the light does not appear in the area of the foot or ineffective for the optics to steer the bottom of the beam splitter / cone. The light can thus be directed in a targeted manner to the effective area on the aforementioned side surfaces of the first optics, at which point all the light that is emitted by the illuminant can then preferably be totally reflected, as has already been described above.
    Further advantages, embodiments and exemplary embodiments are described below with reference to the figures of the accompanying drawings. Show it:

    Patent Office [0039] Figure 7 shows an embodiment of a lamp 1 according to the present invention. The lamp 1 has a lamp optics 10 according to the present invention. Furthermore, the lamp 1 according to the invention has a lamp 2 for coupling light into the lamp optics 10. The illuminant 2 can preferably be an LED or an OLED, the invention being not restricted to this.
    The lamp optics 10 has a first optics 20 and a second optics 30, which are described in more detail below.
    The first optics 20 is also shown in FIG. 1, for example. It can be seen from FIG. 1 that the first optics extends from a flat bottom region 21 to a tip 22. The first optical system 20 also has the side area 23 connecting the base region 21 to the tip 22. As can be seen in Figure 1, the side surface 23 is preferably rotationally symmetrical. As shown, the first optics 20 have an essentially conical shape for this purpose. Other shapes are also conceivable, for example linear, rectangular, square or polygonal shapes, the rotationally symmetrical shape being preferred in order to achieve a particularly low beam divergence of the lamp optics 10.
    The first optics 20 may preferably have a parabolic or circular arc or other curved outer contour running from the base region 21 to the tip 22; thus an essentially convex outer contour. A parabolic outer contour is shown. Ultimately, this also describes the side surface (s) 23 connecting the base region 21 to the tip 22.
    The first optics 20 is preferably designed as a solid body. It ideally forms a beam splitter, with which preferably all light which is coupled into the luminaire optics 10 is divided or 'fanned out' accordingly, so that preferably no direct light passes through the first optics and then leaves the luminaire optics 10 directly.
    5 and 7, the base region 21 of the first optics 20 has a light coupling surface for coupling light into the lighting system or the lighting optics 10. The side surface (s) 23 is (are) designed in such a way that preferably everything on the base region 21 of the first optics 20 is totally reflected into the light coupled into the side surfaces 23. This preferably means that the totally reflected light is coupled out of the first optics 20 on the opposite side surfaces 23 thereof. This is particularly preferably shown in FIG. 5 and also results from FIG. 7b. As can be seen in FIG. 5, the focal point F of the totally reflecting side surfaces 23 is preferably in the center of the base region 21; particularly preferred as the light coupling surface described above. This, preferably in combination with a parabolic outer contour of the side surfaces 23, leads to a particularly effective beam splitting of the entire light coupled into the first optics 20, as is shown in simplified form in FIG. 5 for the right light component. The focal point F of the totally reflecting side surfaces 23 can be inside or outside the first optics 20. In this case, as shown in FIG. 5, for example, it can also lie on a longitudinal axis, central axis or rotational symmetry axis Rt of the first optics 20 or also away from this axis Ri. This can be varied depending on the desired light output.
    According to a particularly preferred embodiment, the illuminant 2 can be provided at a distance from the first optics 20; in particular from the light coupling surface of the first optics 20. This is particularly advantageous because in this way a first light refraction of the light occurs after it emerges from the illuminant 2, in order to thus refract the light in a defined manner before it is coupled into the lamp optics 10. This is particularly advantageous if the side surface 23 of the first optics 20 connecting the base region 21 to the tip 22 extends in an area 24 near the base surface 21 from the base surface 21 to the tip 22 in a widening or cylindrical manner. This can be seen, for example, in FIG. 1. Such a configuration in the foot region of the conical first optics 20 shown here is provided, in particular for procedural reasons, in order to enable the optics to be easily removed from the mold during their manufacture. This area
    5.17
    AT16 245U1 2019-05-15 Austrian
    Patent Office preferably represents an optically ineffective area, which due to its geometric configuration is not suitable for a desired defined light control and should therefore be avoided as far as possible. In this respect, a light control is available which specifically keeps the light away from these areas 24. In this respect, a spacing of a lamp 2 from the first optics 20 with an air gap preferably in between is conceivable, in order to achieve a corresponding refraction of the light emanating from the lamp 2, in order to avoid the ineffective optical region 24 in the beam guidance. This preferred beam guidance can be clearly seen in FIGS. 3a, 5 and 7b.
    Returning to FIG. 7, the light 1 shown or the light optics 10 also has the second optics 30. This optics 30 has an opening 31 into which the first optics 20 protrude at least with its tip 22. There is preferably a distance between the tip 22 of the first optics 20 (more precisely the area 25 of the first optics 20 projecting into the opening 31, which at the same time preferably defines the coupling-out area 25 of the first optics 20) and the area of the second optics 30 delimiting the opening 31 provided in order to enable a defined and targeted light guidance or light control.
    The second optical system 30 is designed in such a way that it couples light coupled out of the first optical system 20 into the opening 31 and deflects it accordingly in order to emit the light coupled into the second optical system 30 in a directed manner from the second optical system 30, as shown in FIG. 7b can be seen. The combination of the two optics 20, 30 according to the invention thus essentially leads to the elimination of an uncontrolled light (portion), as is known, for example, from CPC concentrators (cf. FIG. 4b) or TIR optics (cf. FIG. 4c). The light which is preferably completely split or fanned out via the first optics 20 in the form of a beam splitter can thus preferably be completely collected and directed in a targeted manner entirely via the second optics 30. By avoiding direct light components and the defined light control of the preferably entire light component, the two-stage system enables a particularly low beam divergence.
    The second optics 30, like the first optics 20, can be designed as a solid body.
    The deflection to the directional light output from the second optics 30 is preferably achieved in that the second optics 30 enables a corresponding directed light emission of the light coupled into this optics 30 by means of total reflection. This can be seen, for example, from the light control, as shown in FIG. 7b.
    Possible embodiments of the second optics 30 according to the invention are shown for example in FIG. 6. Thereafter, the second optics 30 preferably have a shape that extends and widens from a side having the opening 31 receiving the first optics 20 away from the first optics 20. As can be seen in FIG. 6, the second optics 30 can consequently have a conical shape in the opposite direction to the first optics 20. This can have a flat bottom area 32 on its side facing away from the first optics 20, which runs towards the first optics 20 towards a flat end area 33. The flat end region 33 can form the entry into the opening 31. In particular, the end region 33 has the opening 31 that at least partially accommodates the first optics 20. This then extends from the end region 33 to the bottom region 32. The shape of the opening 31 is preferably adapted optically and preferably also geometrically to the shape of the first optics 20 - at least to the part 25 to be accommodated in the first optics 20. The opening 31, which at least partially accommodates the first optics 20, can be cylindrical (cf. FIG. 6a) or also conical (cf. FIGS. 6b and 6c). Other configurations are also conceivable.
    As shown in Figure 6a, the opening 31 can preferably be formed continuously through the second optics 30. The decisive factor here is that the structural features of the second optics 30 are retained in such a way that they receive the light emitted by the first optics 20 accordingly (ie couple them in) and then deflect all of the light in a defined manner and preferably emit it in a directed manner.
    6.17
    AT16 245U1 2019-05-15 Austrian
    Patent Office [0052] As can be seen in FIG. 7b, the flat bottom region 32 of the second optics 30 preferably forms the coupling-out surface of the lamp optics 10. According to a preferred embodiment, as shown for example in FIGS. 6a and 6c and FIG. 7, the bottom region 32 has the second Optics 30 a recess 34. This is preferably a central recess 34, which is thus arranged centrally or coaxially with respect to the longitudinal axis, central axis or rotational symmetry axis R 2 of the second optics 30. This recess 34 is used in particular to optimize the volume of the second optics 30 and is therefore preferably provided in an area 35 of the second optics 30 which is not effective for light emission. This can also be clearly seen, for example, in FIG. 7b, according to which the recess 34 lies outside the beam guidance of the lamp optics 10.
    The axes Rj and R 2 are preferably provided coaxially and are congruent with a corresponding axis R of the lamp optics 10.
    According to a preferred embodiment, as shown for example in FIG. 8, the first optics 20 and the second optics 30 can be formed integrally with one another. For this purpose, as shown in FIG. 8, a cylindrical attachment 40 extends from the rear of the second lens 30, which is laterally connected in its end objected to by the second lens 30 to the first lens 20 by means of a connecting area or ring 41. The first lens 20 extends into a cavity 42 formed by the projection 40, which in turn extends into the opening 31 provided in the second lens 30. The first optics 20 thus protrude from the connection area 41 through the cavity 42 into the opening 31 of the second optics 30, in order to thus provide a lighting optics 10, as already described above. The light guidance would then result, as shown, for example, in FIG. 7b. The gap 43 that results between the projection 40 and that of the first optics 20 is given by the manufacturing process and can preferably be reduced to a minimum. The geometry of the areas (40-43), which are in particular ineffective for the light guidance, is not restricted by the invention and can essentially be designed as long as it does not impair the required light guidance.
    It can also be seen in this embodiment that the first optics 20 in its foot region 24, that is to say the region of the side walls 23 facing the base region 21, do not continue the contour of the conical or paraboid-shaped side walls 23, but rather are cylindrical. This is provided in particular in order to bring about a simple demolding of the luminaire optics 10 during its manufacture.
    In a particularly simple embodiment, not shown here, it is also conceivable that the second optic is designed as a simple reflector, which can have essentially the same shape or outer contour as the second optic 30 shown. In particular, the shape of a corresponding reflector should be designed in such a way that the light coupled out from the first optics 20 is deflected in the desired manner in order to enable a particularly directed light emission with a low beam divergence. In this case, the coupling into the opening 31 of such a reflector coincides with the coupling out of the light from the first optics 20 and then corresponds to the light emission in or the opening of the reflector.
    A combination of reflector and solid material as second optics 30 is also conceivable, in which, for example, to increase efficiency, the second optics 30 is provided, for example, on its outer side surfaces 36 with a reflector or reflector material.
    FIG. 9 shows a further embodiment which represents a luminaire optics system 100 according to the invention. Such a lighting optics system 100 preferably has at least two lighting optics 10 according to the present invention. At least the first optics 20 and / or at least the second optics 30 are connected to one another by means of connecting elements 101, 102. These connection elements 101, 102 are preferably, as shown in FIG. 9, in the form of plate-like elements which carry the respective optics 20, 30. Other forms of embodiment are of course also conceivable. As shown in Figure 9, preferably at least two such connecting elements
    7.17
    AT16 245U1 2019-05-15 Austrian
    Patentamt te 101, 102 be provided, in which case a first connecting element 101 carries the first optics 20 and a second connecting element 102 carries the second optics 30.
    The connecting elements 101, 102 may also have fixing elements 103, 104 in order to connect a plurality of connecting elements 101, 102 to one another. By means of these fixing elements 103, 104 it can also be made possible to enable a defined positioning of the two connecting elements 101, 102 or optics 20, 30 relative to one another.
    In a preferred embodiment, it is also conceivable here that the respective optics 20, 30 are integrally formed with the connecting element 101, 102 assigned to them. The entire luminaire optics system 100 can also be integrally formed as a whole.
    [0061] The present invention is not limited to the preceding exemplary embodiments. The features of the individual exemplary embodiments can be combined with one another in any manner, provided that they are covered by the subject matter of the following claims. In particular, the present invention is not restricted to certain materials of the optics and their specific geometry, as long as they fulfill the task of minimizing beam divergence with defined or desired directed light emission.
