    LUMINAIRE LUMINAIRE, LUMINAIRE LUMINAIRE SYSTEM AND LUMINAIRE WITH LUMINAIRE LUMINAIRE
    The present invention relates to a lamp optics with a plurality of optical elements, a lamp optics system consisting of several lamp optics of the aforementioned type and a lamp with the aforesaid lamp optics or with the aforesaid lamp optics system.
    Optical elements, such as in particular reflectors or reflector pots, are known from the prior art. In particular, reflectors are used to direct light from one or a cluster of light sources. Such light sources are often in the form of LEDs. These are usually arranged in a row or in a grid, for example on a circuit board. Up to now, reflectors assigned to the lighting means had to be assigned individually to the respective lighting means. These then each map the alignment of the light sources - here LEDs. This results in a desired lighting (aesthetics) and light effect (radiation characteristic). With the separate arrangement of reflectors, there are usually certain tolerances at the transition from one reflector to the next, which makes it more difficult to arrange or align the individual reflectors uniformly with one another. In addition, different types of luminaires generally have different arrangements of correspondingly provided lighting means, for example in a row or in grid form, which should then each be provided with corresponding reflectors. With an increasing number of illuminants, a uniform alignment of the optical elements becomes more difficult and is also time-consuming.
    It is therefore an object of the present invention to provide a corresponding optical system with which a uniform and simple provision of numerous optical elements is made possible.
    This object is achieved by the subject matter of the independent claims. The dependent claims develop the central concept of the invention in a particularly advantageous manner.
    According to a first aspect, the present invention relates to lighting optics. This has several optical elements which are arranged in a row. Two adjacent optical elements are connected to one another via a flexible joint element; so connected to one another in a bendable manner.
    With such a bendable lamp optics it is possible to provide different optical elements at a defined distance (from one another) and to provide them in any contour of the lamp optics (for example straight, curved, wavy, round). In this way it is made possible to evenly realize a large number of optical elements of the lamp optics; also to create several similar luminaires. In this way, a similar reproducibility can be made possible both with regard to the aesthetics and the emission characteristics.
    In a preferred embodiment, the multiple optical elements have the same orientation. For example, the optical axes of the respective optical elements are all arranged parallel and in series with one another. It is also conceivable that the optical elements are divided into defined optical element groups that repeat themselves in their respective orientation. Here, for example, a periodically repeating arrangement configuration of optical elements lined up in a row is conceivable. In this way, it is ensured that a desired light characteristic and, for example, a defined light emission direction, viewed across the entire light optics, is provided reliably and reproducibly, which leads to a harmonious light sensation.
    The joint areas preferably also have the same orientation with respect to one another, for example at least as the associated - that is, adjacent - optical elements. In this case, leave
    For example, the optical elements are offset uniformly from one another in a bend parallel to their optical axes. Of course, it is also conceivable that the joint areas all have the same orientation (at least in, for example, periodically repeating manner for corresponding optical element groups), but this orientation can differ from the orientation of the optical elements - at least the optical elements assigned to the respective joint area, i.e. adjacent optical elements. The configuration can be selected here as desired, with the connection of the optical elements with the flexible joint element always providing a predefined configuration which can also be handled more easily as a whole.
    In a preferred embodiment, the optical elements on the one hand and the flexible joint element on the other hand are formed integrally with one another. The parts can thus be easily produced in an injection molding process, for example. The light optics are then made in particular from a flexible (optical) plastic. However, other materials are also conceivable as long as at least the flexible hinge element is provided from a flexible material or in a flexible configuration. For example, the optical elements on the one hand and the flexible joint elements on the other hand can be made of two different materials, these being made in a common two-component injection molding process for the lamp optics.
    In a preferred embodiment, the flexible joint element can extend flat between the respective optical elements. Due to the quasi plate-like configuration of such a flexible joint element, a defined bending direction can be specified; for example. About an axis extending in the plane of extent of the joint element.
    The flexible joint element preferably has a joint area which is provided, for example, by a material reduction or material reinforcement and is preferably provided centrally between the respective optical elements. In this way, a defined joint area can be provided, which enables a defined bending of the flexible joint element, so that overall a uniform provision of the individual optical elements can also be ensured during use.
    The flexible joint element can have a projection. This projection can particularly preferably be provided by the joint area provided with a material thickening. This projection is used to mechanically fasten the light optics in a corresponding receptacle. Such a receptacle can be provided, for example, in a lamp on which the lamp optics are to be provided. Such receptacles can be provided, for example, in a corresponding printed circuit board which has the lighting means assigned to the optical elements. This enables the light optics to be easily provided and attached at their defined location.
    The optical elements are preferred reflectors, in particular reflector cups, or lenses. Of course, other optical elements are also conceivable. In particular, however, the aforementioned embodiments are generally assigned in the prior art as separate elements, for example LEDs as lighting means, so that their connection by means of the aforementioned flexible joint elements is particularly preferred.
    The optical elements arranged at the opposite ends of the lamp optics preferably each have a corresponding part of a flexible joint element on the side facing away from the adjacent optical element, which together can form a flexible joint element. In this way it is made possible to provide the light optics in a closed contour in which the opposite ends are connected to one another by means of the corresponding parts of the flexible joint element. For this purpose, the two parts can preferably have corresponding coupling areas. These can at least continue the contour or shape of the lens optics and particularly preferably form corresponding locking elements for the interlocking connection of the two lamp optics ends.
    It goes without saying that it is with the two corresponding parts of the lamp optics
    It is also possible to combine several luminaire optics to form a longer luminaire optic. In this respect, according to a second aspect, the present invention relates to a lamp optics system with at least two lamp optics according to the present invention, which are preferably connected to one another at their ends via the corresponding parts of the flexible joint element. Of course, other connection options are also conceivable. In the simplest embodiment, the two luminaire optics are simply in line with one another. With a luminaire optics or a luminaire optics system described above, it is thus possible to provide a module for straight and arbitrarily curved arrangements, which is also provided in a simple manner not only for different lamp shapes but also for different lamp sizes.
    According to a third aspect, the present invention further relates to a lamp with a lamp optics according to the invention or a lamp optics system according to the invention. Furthermore, a corresponding lamp has lighting means. The optical elements preferably follow a defined contour, in particular of the lamp or also another desired contour, by means of a defined bend over the flexible joint elements. A straight extension of the light optics or the light optic system on a light is also conceivable. The flexible joint elements then “merely” form defined spacers.
    At least one part or each of the optical elements is preferably assigned an illuminant of the lamp. This applies in particular to LED lights, with individual LEDs or LED clusters being assigned a corresponding optical system - for example a reflector pot - for defined light output. As a result of the defined positioning and orientation of the optical elements in the form of the lamp optics according to the invention, a light emission that is as precise and uniform as possible is made possible.
    In a preferred embodiment, the light optics (s) is / are mechanically fastened in corresponding receptacles of the light via their projections - that is, the projections of the flexible joint elements. These receptacles can be provided, for example, in the printed circuit board having the lighting means, which enables a particularly simple assignment of the individual optical elements to the lighting means.
    By bending the flexible joint elements, the optical elements are prestressed in a defined position, alignment and preferably in contact with (structural) areas of the lamp. The residual stress of the material of the flexible joint element thus generated ensures that the optical elements preferably attach to structurally specified contour areas (e.g. radii or lines of the luminaire) and thus enable a particularly precisely defined alignment of the optical elements and thus the contour of the luminaire optics or the luminaire optics system.
    Further embodiments and advantages of the present invention are described in the following exemplary embodiments with reference to the drawings of the accompanying figures. Show it:

    Figures 2a-e detailed views of the light optics according to Figure 1,
    FIG. 3 shows a circularly closed arrangement of the light optics according to FIG. 1 in a side view,
    FIG. 4 shows an enlarged detailed view of an end region of the light optics according to FIG. 1,
    Figure 5 is a schematic representation of a lighting optical system according to the invention,
    6a-c three embodiments of a lamp according to the invention, and
    FIG. 7 shows a perspective view of a round lamp according to the invention with a lamp optical system according to the invention.
    Figure 1 shows a lamp optics 1 according to the present invention. The lamp optics have several optical elements 2, which are shown in an enlarged view in FIG. The optical elements 2 are arranged in series. In each case two adjacent optical elements 2 are connected to one another in an articulated manner via a flexible joint element 3, as can be clearly seen in FIG. 4, for example.
    The optical elements 2 can, as shown in the figures, be, for example, reflectors - here in particular reflector pots. However, it is also conceivable that the optical elements 2 are designed as lenses, for example. A mixture of different types of optical elements per luminaire optical system 1 is also conceivable.
    As shown in the figures, the optical elements 2 and the flexible joint elements 3 can be formed integrally with one another. The light optics 1 is preferably made of a flexible material, in particular plastic. Since a bend is to be carried out in particular via the joint elements 3, the optical elements 2 on the one hand and the flexible joint elements 3 on the other hand can also be made of different materials with different flexibility. The two-component injection molding process, for example, can be used for an integral training. A higher dimensional stability of the optical elements 2 compared to the flexible joint elements 3 can also be set by shaping or wall thickness of the corresponding elements 2, 3. The optical elements 2 are preferably barely deformed or preferably not deformed at all when the flexible joint elements 3 are bent.
    In their basic embodiment, the plurality of optical elements 2 preferably have the same orientation. This can be seen, for example, in FIG. 4, where the optical elements 2 all have the same orientation in space. In particular, the optical axes O of the respective optical elements 2 are aligned parallel to one another here and, like the optical elements 2 themselves, are arranged in series. Other arrangements and orientations are also conceivable here.
    In addition to the aforementioned, preferred orientation of the plurality of optical elements 2 to one another, it is also conceivable that the optical elements are divided into defined optical element groups that repeat themselves in their respective orientation. In other words, the orientations of the individual optical elements 2 of an optical element group can differ from one another, this orientation sequence preferably being repeated quasi periodically in each successive optical element group. In principle, however, other orientations - in particular predefined orientations - of the individual optical elements 2 with one another are also conceivable. This predetermined orientation can preferably be reliably provided due to the connection of the optical elements 2 to one another via the flexible joint elements 3.
    The flexible joint areas preferably also have the same orientation with respect to one another. This is shown by way of example in FIG. 4 by the respective axes A, which are arranged parallel and in series with one another. This orientation of the flexible joint areas 3 can preferably correspond to the orientation of the associated optical elements 2. However, other orientations of the respective axes A are also conceivable.
    The optical elements 2 or groups of optical elements 2 are preferably provided at a defined and preferably the same distance X from one another, as can be seen, for example, from all the figures. This results in an overall harmonious appearance of the luminaire optics 1.
    As can be seen particularly clearly from FIG. 4, the flexible joint element 3 can extend flat between the respective optical elements 2. The essentially plate-shaped extension of the flexible joint elements 3 designed in this way thus specifies a preferred bending axis, which here lies, for example, in the extension plane of the flat, flexible joint element 3. This means that a defined bending direction can be
    will give.
    The flexible joint element 3 can have a (defining) joint area 4. This forms a defined area for the defined bending or relative movement of the adjacent optical elements 2 to one another. As not shown in the accompanying figures, this joint area 4 can be provided, for example, by a material reduction in the form of a film hinge. Alternatively, it is also conceivable to provide this joint area 4 in the form of a material reinforcement which is clearly shown in FIG. This material reinforcement is shown here preferably as a rod-shaped element, which here extends parallel to the adjacent optical axes of the optical elements 2. Other orientations and configurations of this material reinforcement are also conceivable. The joint area 4 is preferably provided centrally between the respective optical elements 2 in order to provide a uniform positioning of the respective adjacent optical elements 2 so that, viewed overall, a harmonious and uniform distribution of the optical elements 2 is made possible over the luminaire optics 1.
    As can be seen in FIG. 4, the flexible joint element 3 can have a projection 40. In the embodiment shown, this is preferably provided by the material reinforcement, that is to say the corresponding joint area 4. This projection 40 is designed in particular in order to serve for mechanical fastening of the light optics 1 in a corresponding receptacle. Such a receptacle can be provided in a lamp body, for example. It is also conceivable to provide corresponding receptacles in a printed circuit board that accommodates the lighting means, so that the optical elements 2 can be assigned directly and in a defined manner to corresponding lighting means in order to achieve the best possible, desired light output or light output characteristic.
    The optical elements 2 arranged at the opposite ends of the lamp optics 1 (see, for example, the left optical element 2 in FIG. 4) can each have a corresponding part 30 of a flexible joint element 3 on the side facing away from the adjacent optical element 2. These two parts 30 together preferably form one of the flexible joint elements 3. FIG. 2d shows an enlarged section D from FIG. 1 in which two lamp optics 1 are connected accordingly. The two illustrated parts 30 are designed as corresponding coupling areas 41, 42. These can, for example, simply reproduce the contour or shape of an integral flexible joint element 3 in an assembled form. In a further embodiment, the two corresponding parts 30 can also be (mechanically) connected to one another in an assembled form, as shown in FIG.
    Figures 2a to c show detailed views from Figure 1 with differently curved joint elements 3.
    By means of the corresponding parts 30 it can be made possible, for example, to provide a closed shape with one or more lighting optics 1 lined up next to one another. This is shown by way of example in FIG. 3, in which several light optics 1 are combined to form a ring-shaped light optics system S.
    FIG. 5 shows schematically how, by means of these parts 30, several light optics 1 can be lined up and thus a corresponding light optics system S can be formed, as is also shown in FIG. 1 by way of example. For the rest, a corresponding light optics system S has the same advantages and configurations as the individual light optics 1. Thus, by connecting several lamp optics 1, a lamp optical system S of any length can be provided, which can be adapted to the given conditions.
    The lighting optics 1 can in principle also be provided in such a way that it is shortened to any length. For this purpose, for example, the light optics 1 is attached to any
    Point in the area of a flexible joint area 3 severed in order to provide a defined number of optical elements 2 in a lamp optic 1. For example, a type of endless light optics 1 can be provided, which can be cut to a defined length in accordance with the respective requirements.
    In Figure 6, three embodiments of a lamp according to the invention are shown in a schematically simple form.
    In Figure 6a, an elongated lamp 10 is shown as an example.
    FIG. 6b shows an example of a round lamp 10, the lamp optics 1 or the lamp optics system S being provided on an edge region of the lamp 10 and surrounding it in a ring shape. Such a lamp 10 is also shown by way of example in FIG. 7 in a perspective view. In FIG. 7, a corresponding luminaire optical system S is provided around the outer edge of the luminaire 10. In the embodiment shown, for example, only one of the light optics 1 forming the light optics system S is illuminated, so that desired light effects can also be generated by combining several light optics 1 or by optionally operating different areas of the light optics 1 or the light optic system S. Due to the defined arrangement of the individual optical elements 2, these act particularly harmoniously.
    FIG. 6c shows an asymmetrical luminaire geometry with luminaire optics 1 provided bent accordingly.
    In principle, as can be seen from FIGS. 2a to c, any bending angles are conceivable. The maximum bending angle results in particular from the shape of the optical element 2 on the one hand, their distance X from one another on the other hand, and the design and orientation of the flexible joint elements 3.
    In a luminaire 10 according to the invention, at least a part or also each of the optical elements 2 can be assigned a light source of the luminaire 10. This can be selected as required, taking into account the achievement of a desired radiation characteristic and lighting effect.
    As can not be seen in the figures shown here, the light optics 1 or light optics systems S are mechanically fastened in the lights 10 via their projections 40 in corresponding receptacles of the light 10, in particular a circuit board of the light 10. This enables a defined alignment and orientation of the optical elements 2 to one another. By bending the flexible joint element 3, the optical elements 2 can also be prestressed in a defined position and preferably in contact with structural areas of the lamp 10 (e.g. a lamp housing) so that they can clearly follow a defined contour of a lamp and thus the appearance of a with the lamp optics 1 according to the invention equipped lamp 10 is increased.
