Description

The invention relates to a luminaire in the form of an interior or exterior luminaire with an elongated base body, which has a longitudinally groove-shaped receiving space in which a lighting means carrying a lighting means and at least one light directing element are accommodated, according to the preamble of claim 1.

Such a lamp is from the DE 102017110428 A1 known. In this lamp, the side surfaces of the base body form the lateral outer surfaces of the lamp. It is therefore not possible there to change the appearance of the lamp, for example with regard to color, structure and material properties, without having to replace the base body and thus the entire lamp. An aesthetically pleasing, simple and inexpensive variability of the lamp depending on its environment, for example depending on a living facility or other external environment, is therefore not given.

The invention is therefore based on the object of creating a lamp according to the preamble of claim 1, in which the appearance of the lamp can be changed in a simple and aesthetically pleasing manner.

According to the invention, this object is achieved by a luminaire having the features of claim 1. Advantageous embodiments of the invention are described in the further claims.

In the luminaire according to the invention, the base body has a side groove on at least one outer side that extends in the longitudinal direction and up to at least one end face of the base body. Furthermore, the luminaire comprises an elongated side panel at least predominantly covering the outside of the base body and at least one connecting element for the detachable connection of the side panel to the base body, the connecting element being insertable into the side groove over the end face of the base body and being held in this with a positive fit transversely to the longitudinal direction.

In the lamp according to the invention, the side panel, d. H. the lateral cladding element for the base body can be detachably fastened to the base body in a simple and quick manner by means of at least one connecting element pushed into the side groove and held in the side groove in a form-fitting manner. Two or more such connecting elements spaced apart from one another are preferably provided in the side groove. The connecting elements can preferably be displaced as desired along the side groove and can be placed in a simple manner at the locations best suited for the detachable connection with the associated side panel. The slide-in technology makes it possible in a simple manner to position the connecting elements on the base body at the desired locations without having to additionally fasten them within the side groove. In particular, it is not necessary to screw or glue the connecting elements to the base body or to screw the side panel firmly to the base body. The use of different side panels and thus a change in the visual appearance of the interior or exterior light is therefore possible in a simple manner. The base body and the components contained therein, such as the lamp holder, lamp and light-directing element (s), can be retained unchanged.

The connecting element is preferably floatingly mounted in the longitudinal direction of the side groove. As a result, the connecting element can be positioned in a very simple manner at the desired location along the base body.

According to a particularly advantageous embodiment, the connecting element is part of a magnetic holder with which the side panel is attached to the base body. As a result, the side panel can be changed without tools, without having to remove the connecting element from the side groove. In particular, the connecting element can be a magnet which interacts with a holding element made of magnetic material, in particular a strip, preferably a steel strip, of the side cover that is fastened to the side cover. Conversely, it is also possible for the holding element fastened to the side panel to consist of a magnet which interacts magnetically with the connecting element arranged in the side groove. Other types of fastening of the side panel on the connecting element held in a form-fitting manner in the side groove are possible.

The side groove is advantageously T-shaped in cross-section and has a first cross-sectional section of greater width and a second cross-sectional section of smaller width, the first cross-sectional section being designed to accommodate the connecting element, while the second cross-sectional section forms a guide for a holding element that is firmly attached to the Side panel is connected. The holding element fastened to the side panel preferably consists of a bar, in particular a steel bar, which can extend at least over the major part of the length of the side panel. As a result, the side panel can be positioned and fastened relative to the base body in a simple and precise manner transversely to the longitudinal direction, for example upwards and downwards.

According to an advantageous embodiment, the base body has two side grooves arranged on opposite outer sides, in each of which at least one connecting element in the form of a magnet is positively held, opposite magnets being polarized such that they attract each other. As a result, the opposing magnets exert a magnetic force relative to one another through the base body, which prevents them from shifting within the side grooves.

The luminaire advantageously has at least one end piece with at least one plug-in tab, which can be inserted into the side groove of the base body from its end face and for positive and / or non-positive mounting on the base body ( 3 ) is trained. In this way, end pieces, which are provided for decorative purposes and / or can also have functional properties, can be attached to the base body in a simple, precise and inconspicuous manner.
