For this purpose, generic lights are designed to be elongated in a horizontal direction on the one hand and on the other hand to provide at the same time an indirect room lighting and a direct room lighting. According to the invention, generic lights are mounted on the ceiling of a room. About the direct room lighting direct illumination of a workplace, such as a desk to be provided on the indirect room lighting backlighting a room should be provided. In generic luminaires, the provision of direct and indirect room lighting is ensured by horizontally juxtaposed sections, namely by at least one indirect gate and by at least one direct section. In a proper installation of a generic lamp in a room, the lamp is mounted on the ceiling of a room that is radiated from the indirect section light from the top of the lamp and of the Direct section light is radiated away from the bottom of the fixture. The terms "top" and "bottom" refer to in a vertical direction, which is perpendicular to the horizontal direction, opposite sides of the lamp. In the case of generic luminaires, the provision of indirect room lighting by the indirect section is preferably ensured in that the indirect section is designed to emit light into a first half-space, which is located at the top of the luminaire, and through a parting plane perpendicular to the vertical is separated from a second half space, wherein the direct portion is adapted to emit light in the second half space.

Due to their described suitability for the illumination of offices generic lights must fulfill various tasks. First, the lights should be visually appealing. On the other hand, the lights should provide as glare-free as possible direct lighting.

In addition, the lights should provide a pleasant backlight. In addition, the lights should be adapted to be adapted to predetermined premises such that for a variety of different sizes of a room to be illuminated and different orientations of the windows in the room a pleasant lighting of the room can be reached. Last but not least, generic lights should also be inexpensive to produce, so that a room can be equipped with a sufficient number of lights, without this being associated with significant costs. These tasks meet generic lights only inadequate. For example, generic lights are available only in predetermined lengths, which makes it difficult to adapt the lights to given premises. Also, a generic lamp is usually not suitable to provide a more pleasant direct lighting a workplace, but there are usually two such lights required to be mounted on one side next to a workplace, so that the workplace is uniformly illuminated from both sides and no glare on a working surface of the workplace arises. In addition, generic lights are perceived by people who are staying in a lit by the lights room, often because of the abrupt change between direct and indirect sections as unpleasant.

The suitability of the indirect section and the suitability of the direct section for respectively providing an indirect or direct room lighting can be provided as explained in the generic luminaires. In general, the luminaire according to the invention can have features which are described above for the generic luminaires from which the invention proceeds. It is essential that the indirect section is designed as described for generic lamps to emit light in a arranged at the top of the lamp first half-space and the direct section is adapted to emit light in a located on the underside of the lamp second half-space , Wherein the two half-spaces are separated from one another by an imaginary sectional plane running perpendicular to the vertical. In particularly preferred embodiments, the indirect section may be formed in addition to providing an indirect room lighting in addition to contribute to the direct room lighting by being designed to emit light not only in the first half-space but also in the second half-space. Likewise, in a particularly preferred embodiment, which is combinable with the aforementioned, the direct section may be designed to contribute, in addition to providing direct room lighting, also to indirect room lighting by sending light not only into the second half space but also into the first half space Half space radiates.

Particularly preferably, the respective areas in which the indirect section exclusively emits light in the first half-space or the direct section only emits light in the second space arranged distributed with respect to the horizontal direction around the center, so that the respective sections only At their horizontal edge regions, light can also radiate into the respective other half-space. In another embodiment, the indirect section is configured to emit light exclusively in the first half-space and the direct section is configured to emit light exclusively in the second half-space. In the luminaire according to the invention, the light sources are arranged on the carrier and / or on the housing, wherein they are preferably arranged such that they are enclosed by the housing in sections perpendicular to the horizontal direction, wherein this enclosing is interrupted by a light exit opening provided in the housing. Preferably both carrier and housing are formed horizontally elongated, wherein the carrier extends over at least 70%, in particular over at least 80% of the horizontal extent of the housing in the horizontal direction uninterrupted. As a result, a particularly high stability of the luminaire can be ensured. In this case, the carrier may be composed of a plurality of carrier elements which are arranged horizontally next to each other but firmly connected to each other, so that the carrier runs horizontally uninterrupted. Particularly preferably, the light sources and in particular an operating device are arranged on the carrier. This can simplify the assembly of the lamp particularly, and in addition light sources and / or operating device can be kept very safe. In general, the operating device, by way of which the light sources of the luminaire are controlled, is particularly preferably arranged inside the housing. Such an operating device may comprise various components, for example an electronic ballast and / or a current and / or voltage limiter and / or a controller which is connected to or provides a light management system. In one embodiment of the invention, the lamp has no such operating device but is powered by an external operating device with power and driven accordingly. In one embodiment, the lamp comprises components of an operating device or components of an operating device are arranged within the housing of the lamp, wherein other components of the operating device outside of the lamp, for example in a ceiling to which the lamp is attached, are arranged. In general, the luminaire is particularly preferably attached via its top to a ceiling. For this purpose, the lamp may preferably have mounting units which are at the top of their Housing are arranged and connected to the housing and / or the carrier, these mounting units via holding devices, such as ropes or wires, is suspended from a ceiling.

According to the invention, the housing is formed from a plurality of, ie at least two, housing elements and the carrier is formed from a plurality of, ie at least two, carrier elements. Housing and support are thus structurally defined by said elements and consist in particular of these elements. The indirect section has a first housing element and a first carrier element which are fixedly connected to a first lamp element. The direct section has a second housing element and a second carrier element, which are fixedly connected to a second lamp element. For example, the first housing element and the first carrier element and / or the second housing element and the second carrier element can each be integrally formed in one piece. Alternatively, the first housing element and the first carrier element and / or the second housing element and the second carrier element are each separate components, which are initially produced independently of each other and then connected to the first and second lamp element firmly together. This connection can be, for example, a non-detachable connection, for example by welding, or alternatively a detachable connection, for example by screwing. The person skilled in various ways to realize a solid connection between the housing element and the support element are known, for example, screw, locking or riveting. In one embodiment, the indirect section consists of the first lamp element and the direct section of the second lamp element, ie the first lamp element forms the indirect section and the second lamp element forms the direct section. The two lighting elements are fixed to each other releasably. Also for such a releasable fixation the usual means are known to those skilled in the art, such as the provision of a locking connection or screw connection or a combination of both. Upon release of the detachable connection of the two lamp elements, the lamp elements are removable from each other, wherein each of the lamp elements comprises its associated carrier element and housing element, which are preferably firmly connected to each other independently of the releasable connection of the two lamp elements. According to the invention, the housing further has, between the two housing elements of the two lamp elements, a recess running vertically from the top to the underside of the lamp for ensuring transversal light emission in a transverse direction which is perpendicular to the horizontal direction and to the vertical direction. The recess thus allows a passage of light between the housing elements of the two adjacent lamp elements. Due to the vertical profile of the recess, the recess allows an optical connection from the top to the bottom, so that light is not only emitted at the top of the indirect section and at the bottom of the direct section but a light path between the two sections is provided , The recess thus runs in any case with a vertical component, but can also be angled to the vertical direction, but extend from the top to the bottom. Particularly preferably, the recess extends continuously from the top to the bottom. Particularly preferably, the recess extends on both transverse sides of the housing in each case from the upper side to the lower side. Particularly preferably, the recess opens at the bottom into a light exit opening provided in the direct section and at the top into a light exit opening provided in the indirect section. This connects the Recess the light exit openings provided in the direct section and the indirect section. Particularly preferably, the recess extends on both transverse sides and terminates respectively at the bottom in a provided in the direct section light exit opening and at the top in a provided in the indirect section light exit opening, so that about the recess in combination with the light exit openings to the housing is provided with respect to the horizontal circumferential opening for emitting light. Thus, in a preferred embodiment, the recess is provided on both transverse sides and extends vertically on both sides from the top to the bottom, wherein through the recess, provided at the top of the housing first light exit opening and provided on the underside of the housing second light exit opening a is provided around the horizontal direction closed circumferential opening in the housing, through which light can pass out of the housing to the outside. This opening does not necessarily have to be perpendicular to the horizontal but, in some embodiments, may also be curved and extend at different angles to the horizontal direction over its course, but always runs closed around the horizontal direction.

Particularly preferably, the housing elements on their inner side and / or the support elements, in particular on their facing the light sources sides, at least partially formed reflective. As a result, a possible loss-free light guide within the housing can be made possible, and in particular a guidance of light to the recess can be ensured in this way.

By providing the recess, there is an abrupt transition between the direct section and the indirect section effectively prevented because the recess allows the escape of light in a transverse direction which is perpendicular to the horizontal direction and in the vertical direction. As a result, the luminaire according to the invention allows a much more pleasant sense of space than luminaires from the prior art. According to the invention the provision of the recess between two adjacent housing elements is made possible in that two adjacent lamp elements are connected to each other via their support members which are disposed within the housing elements, so that over the recess, a lateral light exit opening can be provided, without including the stability of Lamp suffers. Accordingly, a luminaire according to the invention can be provided with a very long horizontal extent, in particular with a plurality of luminaire elements, wherein preferably two adjacent luminaire elements are alternately provided as a direct section and indirect section. While the recess assists a pleasant illumination of a room, the fixation of adjacent lamp elements on their support elements ensures the stability of the lamp and also allows a modular design of the lamp, as depending on the given premises any number of lighting elements can be provided, then on their Carrier elements can be connected together. The connection between adjacent light elements in such a modular luminaire according to the invention can always be provided as explained in the present description, wherein preferably always a direct section is arranged next to an indirect section, so that always a direct radiating light element in addition to an indirect-a radiating lamp element is arranged and these lamp elements as mentioned above and explained below are connected to each other. Particularly preferably, the recess is covered by a translucent optics. By a translucent optics can be prevented because of their diffusely scattering properties a direct view from the outside through the optics into the housing, which may be particularly desirable for covering the support member or the support elements which extend within the housing along the recess. Particularly preferably, the recess has a horizontal extension of at least 0.5 cm, in particular at least 1 cm and / or a horizontal extension, which amounts to at least one tenth, in particular at least one fifth of the vertical extent of the housing over its entire vertical extent. Over a corresponding minimum dimension of the recess over its entire vertical extent, the desired effect of the recess can be achieved particularly advantageous.

Generally, the luminaire preferably has a vertical extent of less than 5 cm, in particular less than 4 cm, over at least 90% of its horizontal extent, and / or a ratio between its transverse and vertical extent of more than 2, in particular more than 2.5. It has been found that a particularly good optical effect in a room can be achieved via such a flat and in particular wide light, since the top and bottom of the lamp are not far apart and at the same time over the wide extension of the lamp a large radiating surface of the lamp can be provided. The invention thus relates in particular straight to such a flat and wide light, wherein despite the geometrical dimensions sufficiently robust light can be provided by the simultaneous provision of housing elements and carrier elements arranged therein and the provision of recesses between the housing elements whose light emission and appearance from People in a room are perceived as very pleasant. Furthermore, the luminaire is generally particularly preferably designed in such a way that, when setting its maximum emission intensity, it has a distribution of the emitted light intensity such that at least 70%, in particular at least 80%, in particular at least 90%, of the light intensity emitted by the luminaire is exclusively in a first, Half space located at the top of the lamp passes. The setting of the light intensity which can be emitted by the luminaire to the maximum can be provided in the case of dimmable luminaires by selecting the maximum light intensity in the dimming parameter. For non-dimmable luminaires, the maximum illuminable light intensity corresponds to the light intensity that the luminaire emits after switching on. The appropriate distribution between the intensity with which light is emitted at the top, and the intensity with which light is emitted at the bottom, has proven to be particularly advantageous, since this can provide a sufficiently bright backlighting of a room. This is based on the finding that for the background lighting of a room preferably a much higher light intensity is to be used than for the direct lighting of a workplace, as this provided sufficient lighting and glare in direct lighting can be avoided if possible.

Particularly preferably, the carrier extends over at least 90% of the horizontal extent of the luminaire in the horizontal direction continuously. Particularly preferably, the support elements of the lamp element extend in each case over at least 70%, in particular at least 90% of the horizontal extent of the respective housing elements of the lamp elements continuously. Due to the corresponding continuous course of the support elements or the carrier the light can be made particularly robust. Particularly preferably, the housing has, at least in sections perpendicular to the horizontal direction, a cross section which forms a U-shape with a base section and an open end opposite the base section in a vertical direction. Particularly preferably, the carrier is arranged within the U-shape of the housing. The U-shape can be realized for example by providing a base portion with two housing legs running vertically to the base portion. For example, the U-shape may be realized by providing a substantially rectangular or oval cross section of the housing to provide a recess at a vertical end of the housing. The U-shape of the housing is realized in particular in that all housing elements have such a U-shape as explained above. The corresponding design of the housing, which forms a U-shape with its cross section, brings several advantages. On the one hand, a light exit opening on the top or bottom can be ensured in a simple manner via the U-shape. On the other hand, the U-shape ensures a high rigidity of the housing, so that the housing can be realized with extremely thin sheets, in particular with sheets having a thickness of less than 1 mm, in particular less than 0.8 mm. In addition, a corresponding configuration of the housing can enable effective concealment of a carrier arranged inside the housing. Particularly preferably, both the first housing element of the indirect section and the second housing element of the direct section each form with its cross section such a U-shape, wherein the open end of the U-shape of the first housing element is arranged on the upper side of the luminaire and wherein the open end of the second housing member is disposed on the underside of the luminaire.

In one embodiment, the luminaire has a first group of light sources, which are arranged exclusively on an upper side of the first carrier element of the indirect section, and a second group of light sources, which are arranged exclusively on an underside of the second carrier element of the direct section, wherein, in particular, the different groups of light sources are independently switchable and / or dimmable. Preferably, the lamp has a control device for ensuring such a circuit and / or dimming. By providing the different light source groups at the top or bottom of the carrier elements, the explained property of the direct section or indirect section can be made particularly simple, wherein the provision of an independent circuit and / or dimming a particularly targeted setting of the radiation characteristics of the lamp allow, in particular an independent variation of the indirect and the direct lighting. Particularly preferably, the luminaire has further groups of light sources, for example further groups of light sources, which are arranged on further support elements further luminaire elements. In particular, in one embodiment, the luminaire has at least one first additional group of light sources, which are arranged on the underside of the first carrier element, and / or a second additional group of light sources, which are arranged on the upper side of the second carrier element, so that the indirect line Section can simultaneously ensure, in addition to indirect lighting of a room, direct lighting of a room and / or the direct section, in addition to direct lighting of a room, can simultaneously provide indirect lighting of a room.

In one embodiment, the first and second support members overlap in a horizontal section and are fixed to each other in this horizontal overlap section releasably. By providing such an overlapping section, a particularly robust attachment of the two adjacent carrier elements to each other can take place. In one embodiment, the overlap portion extends horizontally along the recess. In another embodiment, the overlapping portion extends horizontally within one of the two adjacent housing elements, so that only one of the two adjacent support elements extends horizontally along the recess.

In one embodiment, the support elements of the lamp elements each form with their perpendicular to the horizontal direction extending cross-section of a U-shape with a base region and two thereof vertically extending away wall portions. On the one hand, a particularly robust, torsionally rigid design of the carrier elements can be made possible by the U-shape, on the other hand a simple connectivity of the carrier elements can be made possible, furthermore a robust, smooth mounting surface for the mounting of light sources and / or operating device components can be provided in a simple manner. Particularly preferably, in the horizontal overlapping section the base areas of the two carrier elements abut one another and in the horizontal overlapping section the wall areas of the two carrier elements extend along one another. In this way, a particularly robust detachable fixation of the two carrier elements to each other may be possible. For this purpose, the wall regions of the two carrier elements in the overlapping section are particularly preferably adjacent to one another. Particularly preferably, the light sources are arranged on the base regions of the carrier elements. The base portions each have an inner side facing the wall portions, and an outer side facing away from the wall portions Points away wall areas. The light sources of the above-explained first light source group of the first luminaire element, which comprises the indirect section, are arranged on the outside of the base region of the first carrier element and the light sources of the above-described second group of light sources on the inside of the base region of the second carrier element of the second Luminous element comprising the direct section arranged. As a result, the distance between the light sources of the second light source group and a light exit opening provided on the underside of the second housing element can be kept as large as possible, even in the provision of a flat light, so that the light sources of the direct section for a person in a room on the ceiling the light is attached, as little as possible are visible. Particularly preferably, at least the second carrier element is designed to be reflective on the inside of the base region and on the inner sides of the wall regions facing the base region. This contributes particularly advantageous to a steering of light to the recess.

Particularly preferably, a first vertical distance between a support portion, in particular the base portion of the first support member and an at least partially the top of the lamp forming optical element is less than a second vertical distance between a support portion, in particular the base portion, the second support member and an at least partially the Bottom of the light forming optical element of the lamp, in particular, the second distance is at least 1.5 times, in particular at least 2 times the first distance. In one embodiment, light sources of the respective luminaire module are arranged on the support section of the respective support element. As in the previous paragraph 1, which, unlike the present paragraph, relates to the specific arrangement of the light sources at the base region of the respective carrier element, the described embodiment brings with it the particular advantage that the base portion of the second carrier element that is from the direct section for providing the direct illumination is spaced as far as possible from the optical element, which is visible from a person in the intended use of the lamp from the room to prevent a view of the person on the base portion and disposed thereon elements. The inventors have recognized that such a distance between the support section or base section of the first support element and the optical element forming the upper side of the luminaire is less relevant, since this optical element is not intended to be viewed directly from above by a person as intended. Accordingly, this embodiment is especially advantageous for the realization of a visually appealing, flat luminaire.

In one embodiment, at least one of the support elements extends in the horizontal extension region of the recess, wherein this support element has at its walls in the horizontal extension region of the recess at least one passage for passing light from the inside of the U-shape of the support member to the outside. Particularly preferably, the first and second carrier element extend in the horizontal extension region of the recess and overlap in this area in said horizontal overlap section, the wall regions of both carrier elements each having at least one passage and the bushings of the two carrier elements are aligned with each other for passing light from the Inside the U-shapes of the support elements to the outside. Such passages may be particularly preferred on both transverse sides of the Carrier elements may be provided. The bushings allow in a particularly advantageous manner leakage of light in the transverse direction through the recess, wherein at the same time a high stability is ensured due to the U-shape of the support elements and the continuous wall portions which have only at least one implementation. It will be understood by those skilled in the art that the term "interior" of the U-shape refers to the region of the U-shape surrounded by the base region and the wall region.

In one embodiment, the first carrier element has a first connection side and the second carrier element has a second, with the first corresponding terminal side. The releasable fixation of the two carrier elements can be made possible via the two corresponding connection sides. Particularly preferably, a releasable connection between the adjacent carrier elements is produced by means of horizontal telescoping of the carrier elements, wherein this compound can be released by a horizontal sliding apart. Preferably, securing elements, such as screws or locking devices, may be provided which prevent unwanted sliding apart and thus releasing the connection. By means of the corresponding connection sides, a modular structure can be realized in a particularly simple manner. By the horizontal telescoping a particularly reliable and easy connection of two adjacent support members may be possible.

In one embodiment, the luminaire has an operating device which is arranged horizontally within the indirect section between a section of the underside of the first carrier element and the first housing element. Particularly preferred is a connecting cable for connecting the lamp is provided, which emerges from the top of the direct section, wherein an electrical cable connection is provided between the operating device and the connecting cable and wherein a further electrical cable connection between the operating device and the at least one direct section connected to the indirect section is provided for supplying arranged in this at least one direct section light sources via the operating device, in the indirect section is arranged. At this point, it should be pointed out again that, in general, the luminaire may particularly preferably have a plurality of indirect sections and / or a plurality of direct sections, wherein all indirect sections have further carrier elements and further housing elements with the properties explained with respect to the first carrier element and the first housing element can and all direct sections can have further support elements and further housing elements with the properties described for the second carrier element and the second housing element and two adjacent section or two adjacent lamp elements to each other as explained can be arranged and fixed to each other releasably. Thus, in a particularly preferred embodiment, an indirect section is arranged horizontally between two direct sections, each of the direct sections being electrically connected to the operating section of the indirect section. The provision of the operating device in the indirect section has been found to be particularly advantageous, since between the underside of the first support member and the first housing member may be provided a sufficiently large storage space for a control gear, whereas in the direct sections preferably the greatest possible distance between Carrier element and light exit opening and thus only a smaller storage space between the second support member and the second housing element is provided so that a direct view of the light sources of the direct section can be prevented if possible. The leakage of the cable from the direct section has proven to be extra advantageous, since then the cable does not interfere with the light emission from the top of the indirect section. Preferably, the cable within the housing elements is routed from the direct section and the indirect section from the direct section to the indirect section.

In one embodiment, the upper side of the luminaire is formed in sections by a first optical element and the underside of the luminaire is formed in sections by a second optical element. Particularly preferably, both optical elements are formed translucent at their transverse edge regions. The edge regions preferably have an extent of at least 3%, in particular between 3% and 20% of the transverse width of the respective optical element, starting from the respective transverse end, on each transverse side. Particularly preferably, the optical elements extend with their edge regions into the at least one recess provided between the housing elements and cover this recess. As a result, in the case of a lateral view of the luminaire, a homogeneously diffused light band can be made visible. Particularly preferably, the first optical element has a transparency of at least 90% between its transversal edge regions and is designed here for non-directional transmission of light. Particularly preferably, the second optical element between its transverse edge regions is also formed translucent or designed to effect a predetermined light deflection. For this purpose, the second optical element may comprise optics known from the prior art, for example a prism optics or a foil.

In a further embodiment, which can be combined in particular with the aforementioned, the second optical element protrudes over at least 80% of its horizontal extension, in particular over at least 90% of its horizontal extension over a vertical extension range of at least 0.2 cm, in particular at least 0.4 cm vertically beyond the second housing element. Characterized in that the two optical elements protrude vertically over its associated housing elements vertically, the optical elements are recognizable in a lateral view, as they do not sink into the housing elements, so that realized in a lateral view particularly effective along the horizontal extent of the light extending light strip can be.

In one embodiment, each of the first and second optical elements has a cross-section perpendicular to the horizontal direction having a U-shape with a bottom and side walls extending vertically therefrom, the bottom of the first optical element forming in sections the top of the luminaire and the bottom second optical element sections forms the bottom of the lamp. Particularly preferably, the two optical elements are formed and arranged in the lamp to each other that they overlap horizontally in the region of the recess and are arranged vertically one above the other, in particular vertically abut each other. About the appropriate design and arrangement of the optical elements can be ensured at the same time the cover of light exit openings at the top and bottom of the lamp and the cover of the recess in a particularly simple and expedient manner. Particularly preferably, the first housing element engages behind the first optical element on its upper side for holding the first optical element. Particularly preferred behind the second housing member, the second optical element on its underside for holding the second optical element. Particularly preferably, the engagement behind takes place on both transverse sides of the respective optical elements. Particularly preferably, the first optical element is supported relative to the first carrier element or relative to the first housing element via a first support which presses the first optical element against the rear handle provided by the first housing element. Particularly preferably, the second optical element is supported via a second support on the second carrier element or the second housing element, via which the second optical element is pressed against the rear handle provided by the second housing element.

It should again be noted at this point that the luminaire preferably has a plurality of indirect sections and / or a plurality of direct sections. Each indirect section may comprise a luminaire element having the characteristics as explained with respect to the first luminaire element, and thus a carrier element, housing element and optical element assigned to it which has properties as described for the first carrier element, the first housing element and the first optical element. Correspondingly, each direct section may comprise a luminaire element which has a carrier element, housing element and optical element assigned to it, which has properties as explained for the second carrier element, second housing element and second optical element. Particularly preferably, the luminaire has at least two direct sections, wherein the indirect section is arranged horizontally between the direct sections. Of course, the light on the outside of the one indirect section may have further indirect sections. In one embodiment, the two direct sections each have an asymmetrical emission characteristic. In one embodiment, the two direct sections each a symmetrical radiation characteristic. About the asymmetric radiation characteristic can be particularly preferably made possible without glare radiation directly into the room, as on the asymmetric radiation light can be emitted from both sides below the indirect section, which can then be arranged, for example, over a workstation. In one embodiment, the luminaire comprises at least two indirect sections, wherein the direct section is arranged horizontally between the two indirect sections. Of course, the lamp may have other direct sections outside of the one direct section.
