The arrangement has a light emission area 1, and an edge area 2, which is formed extending around the light emitting area 1 around. As in the example shown, the arrangement as a whole is shaped to be a flat unit.

In Fig. 2 a cross-sectional sketch of a peripheral portion of the arrangement is shown. In the example shown, the light-emitting region 1 comprises a cover element 10 and a carrier element 15, the design being such according to the invention that an interior 17 of the light-emitting region 1 is formed by the cover element 10 and the carrier element 15. In the interior 17, a light source for generating a light is emitted, which is discharged through the arrangement in an outdoor space.

According to the invention, the light-emitting region 1 is designed to be closed in a housing-like manner. For this purpose, the design may, for example, be such that the carrier element 15 extends as close as possible to the cover element 10, so that an inadvertent penetration by a user of the arrangement between the two components 10, 15 into the interior 17 is practically prevented. In this way, suitable protection against inadvertent contact with the light source or with other components of the light emitting region 1 which may be located in the interior space 17 and possibly carry current can be formed.

In the example shown, the light-emitting region 1 comprises a plurality of reflector-cell-like cells, which are arranged together in a grid pattern. This grid area formed in this way can be formed in particular by a grid element which is preferably formed by the cover element 10 or designed as part of the cover element 10. The at least one light source can be formed, for example, in the form of LED light sources (LED: light-emitting diode), the design being, for example, such that a light emitted by the LED light sources passes through the cells of the raster element or cover element 10 is discharged through into the outer space of the arrangement. In the example shown, the light emitting area 1 exemplarily has thirty-two LED light sources and thirty-two cells, each of which emits the light of an LED light source through a cell. The cover 10 is preferably designed opaque or opaque; In this case, an opening can be formed through each cell, through which the light is emitted. For example, lenses may be used in these openings.

The light emitting area 1 may be configured to be arranged for operation so that the light emitted from the array is emitted downwardly. It can be provided that the cover 10 has a downwardly facing flat surface area 19 which extends horizontally in the intended orientation and is formed by the particular an outer surface region of the arrangement. In the following it is assumed that such an orientation of the arrangement. However, in principle, a different orientation of the arrangement to the operation be provided for the vertical; In this case, the directions etc. are to be reinterpreted accordingly in this description. Accordingly, in the example shown, the cells of the raster element are arranged in a horizontal plane, in the orientation of the arrangement considered here.

Preferably, the support member 15 is mechanically connected to the cover 10, for example via a latching connection. The carrier element 15 is furthermore preferably designed such that it comprises the light sources of the light emission region 1 from above and on all sides, for example in a first approximation in the shape of a cuboid.

The edge region 2 of the arrangement has a support part 3, which is suitable for supporting the arrangement and which is designed to extend at least substantially in a plane E, this plane E being a horizontal plane in the orientation considered here. The support member 3 may in particular have a downwardly facing surface region 5, which is suitable for supporting the arrangement, for example - as in Fig. 2 indicated - to rest on at least one T-beam 20 a suspended ceiling. The downwardly facing surface region 5 of the support part 3 is therefore preferably designed plan. Preferably, the support part 3 extends around the light delivery area 1 on all sides, in particular in a ring-like manner. In this way, the arrangement can advantageously be placed on at least two opposite sides corresponding to T-beams 20. Thus, the arrangement is in this embodiment, in particular as an insert light.

Furthermore, the edge region 2 comprises a side wall region 4, which is formed by the support part 3 at least substantially in a direction perpendicular to the plane E projecting. In particular, in the orientation of the arrangement considered here, the side wall region 4 extends upwards from the support part 3. By the side wall portion 4 can be advantageous attack points for a mechanical connection of the arrangement with a lamp housing, for example in the form of a light pan.

Accordingly, according to the invention, a lamp is provided which comprises an inventive arrangement, and a corresponding lamp housing, in particular in the form of a light sump, wherein the arrangement is mechanically connected to the lamp housing.

How out Fig. 1 By way of example, the design is preferably such that the side wall region 4 is designed to extend in a ring-like manner around the light emission region 1. This makes it comparatively easy to achieve a particularly suitable stability of the edge region 2.

In the example shown, the side wall portion 4 has a uniform height H at all points. Preferably, the design is such that, with respect to the plane E, the height H of the sidewall region 4 varies over the entire length of the sidewall region 4 by less than 20%, in particular less than 10%.

As mentioned, the side wall region 4 can thus form points of attack for a mechanical connection of the arrangement with a luminaire housing. Fig. 3 shows by way of example in a cross-sectional sketch a peripheral portion of the arrangement, mechanically connected to such a lamp housing in the form of a lamp cover 8, here an extension trough 82, which is provided or designed for attachment to a ceiling. Accordingly, it can be formed by the mounting trough 82 and the mechanically connected to this arrangement, a surface-mounted luminaire, such as a ceiling-mounted luminaire.

According to the invention, at least one, also in FIG Fig. 1 designated, recess 6, for example in the form of an opening for engagement formed at least one mounting member of a lamp housing. The mounting element may be, for example, a mounting spring 7 of the mounting trough 82.

This design is particularly suitable in the case of a surface-mounted luminaire, because in this way the space within the extension trough can be used particularly well.

As in Fig. 3 shown by way of example, the at least one mounting spring 7 can be fastened to the latter at a corresponding distance from an outer edge region of the mounting trough 82, that is, as it were, offset a little bit inwards. At its lower end region, it may have an inwardly directed projection which is provided for engagement in the at least one recess 6.

To assemble the arrangement with the mounting trough 82 it can be provided that the trough 82 is aligned with its opening downwards, for example by attachment to a ceiling surface and the arrangement is then moved from below into the mounting trough 82, wherein the at least one Mounting spring 7 slides along the outer surface of the side wall portion 4 until it engages with its projection in accordance with the at least one recess 6.

According to the invention, the arrangement is further designed such that - as also exemplified in Fig. 3 sketched - the support part 3 of the edge region 2 has a projection 9, which extends with respect to the light emitting area 1, in particular on all sides, beyond the side wall portion 4 outwards. In this way, a particularly even appearance of the surface-mounted luminaire can be achieved when viewed from below or diagonally below. The projection 9 may preferably - advantageously with respect to the external appearance - extend at least substantially to all sides as far or at least as far as the mounting trough 82. For example, it may be provided that the projection 9 has a width b , the is greater than 5 mm on all sides, preferably greater than 1 cm.

In Fig. 4 is shown a further example in which the lamp housing is given in the form of a mounting trough 81, which is provided or designed for installation in an installation opening of a ceiling. Accordingly, the arrangement with the mounting trough 81 can be combined to form a recessed luminaire or recessed ceiling luminaire. In this case, leveling elements can be provided, which are connected to the mounting trough 81 or can be designed as parts of the mounting trough 81, by means of which the luminaire can be suitably adjusted in relation to the surrounding ceiling surface in its vertical position.

In contrast to the above, it can be provided here that the at least one mounting element or correspondingly at least one mounting spring 7 'is arranged to contact the side wall area 4 from the inside with respect to the light output area 1. This makes it possible in particular to avoid that the mounting element collides with an installation of the recessed light in an installation opening with an edge of the mounting hole.

For assembling the arrangement with the mounting trough 81 it can be provided that the mounting trough 81 is aligned with its opening downwards, for example by installation in a corresponding installation opening and the arrangement is then moved from below into the mounting trough 81, wherein the at least one Assembly spring 7 ', for example, guided by a, formed below the corresponding projection bevel, on the inner surface of the side wall portion 4 slides along until it snaps into the at least one recess 6 accordingly.

In any case, the arrangement preferably has at least two recesses 6 and the relevant luminaire housing or the relevant luminaire pan 81, 82 at least two, corresponding thereto mounting elements, with respect to the light emitting area 1 on two opposite sides. However, particularly preferably at least four recesses 6 and corresponding thereto mounting elements are provided, so that in the case of a rectangular design of the edge region 2 of the arrangement on each of the four sides in each case a support point can be formed for mechanical connection.

Advantageously, with regard to the external appearance of the arrangement or a corresponding luminaire, it can be provided that the covering element 10 of the light-emitting region 1 merges into the edge region 2. In particular, an integral configuration of the cover element 10 and the edge region 2 can be provided. Like, for example Fig. 2 can be seen in the example shown, the downwardly facing planar surface portion 5 of the support member 3 in a plane with the downwardly facing planar surface portion 19 of the cover 10 is configured. The two mentioned surface areas 5, 19 are preferably designed to be flowing into one another.

Due to the special configuration of the arrangement can be achieved that the arrangement can be used particularly suitable as an insert light or for a surface-mounted luminaire or for a recessed luminaire. In this case, the arrangement is readily suitable as an insert light and in this respect constitutes a "base light" in itself. For use in a surface or recessed luminaire, it is mechanically connected to a corresponding with a mounting trough or a mounting tray.
