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 shape of the luminaire housing also depends in particular on the material to be used, since this often allows only certain shapes. If, for example, metal or sheet metal is used as the housing material, then this leads predominantly to housing types with sharp-edged corners. Other materials in turn also allow the realization of rounded designs, but this often involves an increased production cost.
  • a lighting unit that has a housing that defines a light exit area for emitting light. From a bottom surface of the housing side walls extend to the light exit area.
  • a kit for a lamp which has polypropylene film moldings.
  • the moldings are intended to be mated together to form a lamp housing.
  • 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 basic idea of the present invention is to use a novel housing in which a material which is flexible in a first direction and is rigid in a second direction which is substantially perpendicular to the first direction is used to form at least part of the side walls is.
  • the invention proposes a luminaire with a housing for accommodating at least one light source, the housing defining a light exit area for emitting the light emitted by the light source and having side walls extending from a bottom surface of the housing to the light exit area, and wherein at least a portion the side walls of the lamp housing is formed of a material which is flexible in a first direction and in a second direction which is perpendicular to the first direction, rigid.
  • the material of the side walls is therefore flexible, in particular in the circumferential direction of the housing and rigid in the direction from the bottom surface to the light exit region. It can be provided in particular that the side walls of the lamp housing are completely formed by this material. In such cases, it may further be provided that the material which is flexible in the first direction is interconnected at joints by means of connecting elements, in order thereby to create a stable housing.
  • a so-called web plate material is used as the material for forming the side walls.
  • which may be formed in particular meander-shaped and made of sheet metal, preferably aluminum. It has been shown that such a web plate material particularly well meets the above requirements, since it has a great flexibility in the circumferential direction of the lamp, so it can be well adapted to the desired luminaire shape.
  • there is a very high stability or bending stiffness along the individual webs so that despite the flexibility in the circumferential direction, a stable light housing is created, which meets the highest requirements.
  • the web plate material has on its inner and / or outer side a milling or perforation, whereby special optical effects that can be used, for example. For indirect lighting, are achieved.
  • 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.
  • the bottom surface of the lamp housing according to the invention is preferably formed by a bottom plate, which is provided for attachment to a wall or a ceiling of a room to be illuminated.
  • This base plate can carry all the relevant components of the lamp and accordingly, in particular means for holding the light source and - if necessary - have an associated lamp operating device.
  • the bottom plate may have a wall extending in the direction of the side walls of the housing, which wall is at least partially permeable to light.
  • a lateral light output is achieved in the bottom region of the lamp housing, whereby the light surrounding the wall or ceiling area is somewhat brightened.
  • the light transmission could, for example, be achieved in that the addressed wall of the bottom plate is perforated or formed by a perforated metal strip.
  • color filters are arranged in this area in order to influence the laterally emitted light with respect to its color.
  • a transparent cover pane is furthermore preferably arranged, which, for example, can be designed as a diffuser.
  • light is emitted as uniformly as possible over the entire opening of the luminaire housing.
  • it could be provided that within the cover at least one further radiation area is formed, which is provided for emitting the light of a further light source. If, for example, an emitter is used as a further light source for this purpose, the large-area light output via the cover plate can be supplemented in this way by targeted illumination by means of a radiator. As a result, the possible uses for the lamp according to the invention can be additionally expanded.
  • a particular advantage of the luminaire housing according to the invention is that due to the choice of the specific wall material it is possible to form housing of different shape. Accordingly, it is preferably provided that the side walls form a peripheral shape of the lamp housing, which has no sharp-edged corners. In particular, the peripheral shape may be round or oval. A particularly appealing lamp is also achieved by a slightly amoeba-like shape.
  • 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 basic shape of the lamp is characterized by an in Fig. 1 unrecognizable bottom plate defines the objectionable opposite a Lichtabstrahl Scheme 3 is formed, wherein in the emission area 3, a light-transmitting light exit element 6 is arranged. This is preferably a diffuser over which light can be emitted over a wide area and homogeneously.
  • 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 recording room can be closer to the other representations of the Fig. 2 to 6 are taken, which show different views of the open lamp 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 one in the Fig. 2, 5 and 6 recognizable slight 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 is closer in the Fig. 7a and 7b shown.
  • the material according to the invention for the side walls 5 is characterized in that it is formed by a so-called web plate material.
  • a web plate material This is, for example, a metal or sheet metal strip, preferably made of anodized aluminum, the - as in particular the enlarged view in Fig. 7b can be removed - is curved meandering.
  • the sheet-metal strip therefore has a periodic shape which is formed by outer wall regions 20 and inner wall regions 21 which are arranged alternately parallel to one another and which are connected to one another via intermediate wall regions 22.
  • Such a molded web plate material is characterized in that it in the circumferential direction of the housing, which in Fig. 7b schematically represented by the double arrow I, is extremely flexible.
  • 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 clearly showing a second embodiment of a luminaire 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 entire housing is now held together by the flexible wall material is placed around the cover 6 and the housing ring 8, thereby forming an open towards the top, cup-like body. This is then fastened by means of the brackets 8 to the base plate 4, whereby the housing is closed as a whole.
  • the arrangement is further stabilized in that the wall material is held together at joints by means not shown brackets. In this way, the side walls are closed in the circumferential direction, so that they create tightly around the cover plate 5 and the housing ring 8.
  • On the bottom plate 4 in turn are the aforementioned Light sources 30 and lamp operating devices 31 are arranged, wherein for holding the light source 30, for example, a corresponding lamp socket 32 is used.
  • the bottom plate 4 has no wall, but also here an indirect light output can be achieved, since the ring 8 is arranged with the side walls 5 by the brackets 40 slightly spaced from the bottom plate 4.
  • the design options for the luminaire according to the invention are further expanded.
  • the Fig. 9 to 13 show, so different forms can be realized.
