Definitions

  • the present invention relates to a luminaire according to the preamble of claim 1, which has a housing for receiving at least one light source, wherein the housing defines a light exit area for emitting the light emitted from the light source and has side walls extending from a bottom surface of the housing to the Extend light exit area.
  • Luminaires which are intended for mounting or partial installation in ceilings or walls, are available in a wide variety of designs. While in so-called. Recessed luminaires, which are completely submerged in a mounting hole of a ceiling, the design of the lamp housing plays a minor role in such surface-mounted lights, the housing is designed such that it fits harmoniously into the overall impression imparted by the luminaire. For this purpose a variety of materials for the design of the luminaire housing are available.
  • the present invention is therefore based on the object of specifying a novel solution for the design of a lamp, with the possibility of making the housing of the lamp in its shape extremely flexible, without this being associated with a significantly higher cost.
  • the mentioned choice of material according to the invention of a wall material that is flexible in the circumferential direction results in that the material can be adapted to the desired housing shape in a very simple manner.
  • the side walls must be additionally stabilized in order to permanently maintain the desired shape.
  • the side walls are then held on a housing ring, which is formed from a rigid material in the circumferential direction and extends along the inside of the housing.
  • Fig. 1 shows a perspective view of a generally provided with the reference numeral 1 lamp according to the invention, which has a lamp housing 2, which is pronounced in terms of its design to the shape of a kidney.
  • the housing 2 is characterized in particular in that, viewed in the circumferential direction, it has no sharp-edged corners. Such often referred to as "organic" form gives the lamp 1 a special, interesting appearance.
  • the bottom plate is connected to the diffuser 6 via side walls 5, so that these three elements form the lamp housing 2 with a receiving space for receiving light sources.
  • This receiving space can be more closely taken from the further illustrations of FIGS. 2 to 6, which show different views of the open luminaire housing 2.
  • the bottom plate 4 is used to hold the essential lighting components within the lamp housing 2. These are in particular light sources in the form of circular fluorescent lamps 30 and associated lamp operating devices 31, which are formed in the example shown by electronic ballasts (ECG).
  • ECG electronic ballasts
  • the bottom plate 4 holes or openings, which allow screwing the bottom plate 4 to a ceiling of a room to be illuminated.
  • the luminaire 1 according to the invention could also be mounted on a wall, that is to say vertically aligned.
  • the light emitted by the fluorescent lamps 30 is emitted primarily through the transparent cover 6, which - as already mentioned above - is designed as a diffuser.
  • the luminaire 1 also allows a certain brightening of the surrounding ceiling area. This is achieved in that the bottom plate is bent in its edge region or has a recognizable in Figs. 2, 5 and 6 easy wall 41, which extends in the direction of the side walls 5 of the housing 2. Because of this wall 41, the side walls 5 are not directly on the ceiling or a wall, but are arranged slightly spaced therefrom. It can now be provided that via this wall 41 itself is a light output, for which it is formed teillicht fashion equipment.
  • the wall 41 is perforated or designed as a perforated plate. In this way, a small portion of the light from the fluorescent lamps 30 is emitted laterally to lighten the surrounding ceiling area. It can be provided in particular that on the inside of the wall 41, a color foil or similar elements are arranged to change the side emitted light in terms of its color.
  • a particular feature of the luminaire 1 according to the invention is the design of the sidewall region, which will be discussed in more detail below.
  • the peculiarity is that a material is selected for the side walls 5, which on the one hand is flexible in one direction and, on the other hand, rigid in a second direction perpendicular thereto.
  • the use of such a material makes it possible to realize a wide variety of shapes for the luminaire housing 2 in a simple manner.
  • a particularly preferred material for this purpose is shown in more detail in FIGS. 7a and 7b.
  • this material is rigid in the direction indicated by the arrow II along the individual webs. This makes it possible to adapt this material in a simple manner to the desired luminaire shape. Despite all, a very stable luminaire housing is achieved, as in the connecting direction between the bottom plate 4 and light exit region 3, a high stability prevails.
  • the material for the side walls 5 of the lamp housing 2 may be formed opaque.
  • the side walls 5 have a specific pattern or a perforation.
  • the outer wall sections 20 and / or the inner wall sections 21 can be correspondingly milled or perforated, in which case light is also emitted laterally via the corresponding hole pattern. In this way, a variety of lighting effects can be achieved.
  • the ribbed web plate material gives the luminaire housing a particularly high-quality appearance.
  • Fig. 8 shows a second embodiment of a lamp 1 according to the invention.
  • the lamp 1 is shown in exploded view, so that again its structure can be described in more detail.
  • the main components of the lamp housing 2 are formed by the bottom plate 4, the side walls 5 and the opposite light exit plate 6 in the form of a diffuser.
  • the connection of these elements with each other now takes place in that the bottom plate 4 is first connected via a plurality of retaining clips 40 with a housing ring 8.
  • This housing ring 8 consists of a circumferentially rigid or stable material and serves to support the side walls 5.
  • the material of the side walls 5 in its upper region a first groove 51, in which the housing ring 8 engages.
  • a second groove 52 is provided in the lower end region of the housing walls 5, wherein in this lower groove 52 on the one hand the cover and on the other hand a closing ring 7 engage.
  • the joining and clamping of the wall material 5 at joints is in particular already sufficient for the formation of a dimensionally stable light housing, if this has only outwardly curved areas.
  • a designated by the reference numeral 25 area is provided in which the side walls 5 are curved towards the inside of the housing 2 out.
  • a special stabilization is provided in this case.
  • an additional retaining element 81 which corresponds approximately to the housing shape, is provided in the form of a plate, which holds the housing wall.
  • the wall material can be connected to the holding element 81 via brackets.
  • FIG. 15 shows a further exemplary embodiment of the luminaire 1 according to the invention.
  • This second light exit region 103 which is of circular design in the illustrated embodiment, can now be used, for example, to emit the light of a radiator arranged in the housing 2.
  • the arrangement of this second Lichtabstrahl Schemes 103 can be freely selected within the first light exit area.
  • a luminaire is created by the present invention, which is extremely flexible in terms of design options.
  • a wide variety of housing shapes can be realized without the need for special additional processing of the material would be required.
  • the use of the material according to the invention for the side walls makes it possible to adapt the shape of the housing to a wide variety of desires and at the same time to give the luminaire an interesting appearance.
