Definitions

  • the invention relates to a ceiling lamp with a housing consisting of a side wall and end wall frame in which lamp holders, at least one ballast and a lamp grid consisting of side rails and intermediate webs are fastened and which is closed at the top by an upper wall and at the bottom one from an inward direction Has border limited frame opening, the width of which is smaller than the frame width.
  • the usual ceiling lights with fluorescent lamps have a box-shaped housing that contains the electrical and lighting components and is closed at the top by an upper wall and open at the bottom.
  • the grid of the reflector device In order to ensure glare-free illumination, the grid of the reflector device must have a certain height, as a result of which the height of the lamp housing is significantly determined.
  • the box-shaped lamp housing has because of the large construction height a chunky look. It is also known to design the upper wall of the lamp housing as a transparent plate, so that part of the light emitted by the lamp is directed upwards in order to achieve indirect ceiling lighting. If the luminaire housing is arranged at a relatively short distance below the ceiling, part of the ceiling is illuminated relatively strongly, which can lead to undesirable lighting effects and reflections in monitor spaces.
  • Ceiling lights are also known, in which the side walls of the frame also extend over the entire height of the housing, consist of three strips, of which the central strip is offset to the outside.
  • a luminaire housing appears slimmer and flatter because the upper and lower stripes of the side wall recede in appearance, the upper stripe generally being covered by the outwardly protruding middle stripe when the luminaire is suspended.
  • the frame which forms the supporting part for the lighting and electrical components, extends over the entire height of the housing and the top wall that closes off the frame is flat.
  • the changes in the light guide are essentially limited to the fact that different reflector devices can be used.
  • the invention has for its object to provide a ceiling lamp of the type mentioned, the housing when using a reflector device, which causes glare-free illumination, has a slim and pleasing appearance and it in particular also allowed to achieve an advantageous light emission upwards.
  • the solution to this problem consists in that the upper wall of the housing consists of an attachment attached to the frame, the height of the frame is greater than 1/5 of the frame height and the width is at most as large as the width of the lower frame opening and that the lamp holders protrude into the interior of the attachment.
  • the height of the frame which forms the supporting component for the electrical and lighting components, is smaller than the height of the light.
  • the attachment placed on the frame which springs back on the sides and on the front sides opposite the frame, enlarges the lamp housing upwards.
  • the high arrangement of the lamp in turn enables the use of higher ridges on the grid.
  • larger and higher reflectors can be used, whereby the light exit opening of the lamp can be enlarged and the efficiency can be increased with the same shielding angle.
  • High reflectors achieve better light control with a sharp limitation of the emitted light.
  • the attachment is separate made of the frame and only attached to it later. This makes it possible to provide the lamp with different attachments.
  • An attachment preferably consists at least partially of transparent material. Since the attachment not only has an upper wall, but also (vertical or inclined) side walls, the light emitted through the attachment can also be distributed laterally so that there is no strong local light concentration on the ceiling. A broadly distributed skylight under the ceiling prevents the brightness of the ceiling from becoming too high locally. This is particularly important in rooms with VDU workstations.
  • the ceiling lamp according to the invention enables numerous variations with the same basic structure. It can be attached directly under the ceiling, with the structure touching the ceiling. Even in this case, ceiling lighting is possible through side light emission from the attachment. Alternatively, the ceiling light can also be attached with spacers under the ceiling or hung on pendulum tubes. In any case, in addition to the downward light emission, it is possible to use an upward light emission if an attachment is used that is completely or partially translucent. A special effect is achieved in that the attachment, which springs back laterally relative to the frame, is generally not visible from below at all and that the lamp shines through this attachment from the side, so that the impression is created that there is an additional light source emitting to the side above the visible part of the luminaire housing.
  • the in Figs. 1 to 4 shown ceiling lamp has a substantially rectangular elongated housing 10 in plan, which consists of the frame 11 and the attachment 12.
  • the frame 11 forms a rigid unit, which is made of metal and represents the supporting structure of the housing 10.
  • Two essentially C-shaped profiles 13, 14 of mutually identical shape form the longitudinal frame parts and similarly shaped profiles 15 form the transverse frame parts.
  • similarly shaped profile corners 16 are provided on the frame corners, their main surfaces (in plan view) at an angle of 45 ° to the main surfaces of the longitudinal profiles 13, 14 and the transverse profile corners 15 (see FIG. 4).
  • Each of the profiles has a horizontal upper wall 17, an inclined surface 18 projecting downwardly from the outer edge of the upper wall, a side wall 19 projecting vertically downward from the lower end of the inclined surface 18, a recessed sloping surface adjoining the lower end of the side wall 19 20 and a horizontal bottom wall, which forms the edge 21 of the lower frame opening 22.
  • the inclined surfaces 18 and 20 are arranged exactly one below the other. Their helix angles are the same, but opposite.
  • the side walls 19 form the lateral outer boundary of the frame 11.
  • each profile 13, 14 there are inwardly directed flanges 23, 24, of which the flanges 23 delimit the longitudinal upper opening 25 of the frame 11, while the flanges 24 delimit the lower frame opening 22.
  • the upper frame opening 25 is smaller than the lower frame opening 22 both in the longitudinal direction and in the transverse direction.
  • the profiles 15 and 16 are shaped in the same way as the profiles 13 and 14 described above. While the profiles 13, 14 and 15 are cut off at right angles at the ends, the profiles 16 are cut off at both ends at an angle of 45 °.
  • form-fitting corner connectors for example made of cast aluminum or plastic, can also be used.
  • the attachment 12 which closes this frame opening, is fastened to the upper frame opening 25.
  • the attachment 12 consists in the illustrated embodiment of a sheet metal hood, which is painted white or mirrored on its underside. Alternatively, the attachment 12 can be made entirely or partially of translucent material.
  • the attachment 12, which protrudes from the frame 11, has a flat top wall 26, from the side edges of which inclined surfaces 27 extend downward at 45 °. At the lower end of the inclined surfaces 27, vertical flanges 28 are provided, which abut against the flanges 23 of the frame 11 and are fastened to them.
  • the height H A by which the attachment 12 projects beyond the frame 11 is at least 1/5 of the height H R of the frame 11 and is preferably greater than 1/4 of the frame height H R.
  • the slope of the inclined surfaces 27 is at most as large as the slope of the inclined surfaces 18.
  • each lamp socket 28 is fastened to a socket holder 30, which in turn is fastened inside the frame 11, but projects into the interior of the attachment 12.
  • the luminous grid 31 has two longitudinal arcuate side strips 32 which, in the present exemplary embodiment, protrude into the vicinity of the top wall 26 of the attachment 12.
  • the lower ends of the side strips 32 are bent outwards and upwards and form flanges 33 which are set against the flanges 24 of the frame 11 from the inside.
  • the light grid is detachably connected to the frame by means of closures (not shown).
  • Transversely extending intermediate webs 35 made of reflective material extend between the two side strips 32, the mutual spacing of which increases downwards.
  • Each intermediate web 35 is designed in a known manner as a wedge-shaped hollow body (Fig. 2).
  • the ends 35a of the intermediate webs 35 are designed as tabs which are snapped through openings in the side strips 32 in order to lock the intermediate webs 35 on the side strips 32.
  • the grid 32, 35 formed from the side strips 32 and the intermediate webs 35 forms an inherently rigid grid insert which is pushed into the frame opening 22 from below and fixed by the closures.
  • the intermediate webs 35 extend from the lower end of the frame opening 22 up to the vicinity of the lamp 29, so that the upper web ends are in the upper third of the frame 11.
  • a transverse wall 36 (FIG. 2) is fastened between the two flanges 23 and 24 of the profile 15. From this vertika len transverse wall 36 is a punched tab 37 horizontally bent outwards. Through a hole in this tab 37, the end of a pendulum tube 38 can be inserted, which is attached to the ceiling to hang the lamp.
  • the frame carrier 30 is also fastened to the wall 36.
  • the pendulum tube 38 projects through a breakout opening provided in the inclined surface 18 of the profile 15. When using pendulum tubes 38, the frame 11 is thus suspended at its ends projecting beyond the attachment 12. This state is shown in Fig. 5.
  • the frame 11 can be used in connection with different attachments 12. It is possible to use an attachment in which only the inclined surfaces 27 are translucent, while the top wall 26 is opaque, or an attachment which is translucent overall. If the inclined surfaces 27 are translucent, a reflector device 31 is used, in which the reflectors 32 do not protrude into the vicinity of the upper wall 26, but are shorter so that the light from the lamp 29 can fall onto the inclined surfaces 27.
  • the attachment 12 springs back both laterally and on the front sides relative to the frame 11, it is not visible at all when the lamp is hung sufficiently high.
  • the frame 11 which has a relatively low height anyway, is given a flat and pleasing appearance.
  • ballast 40 housed in the cavity between a side profile 13 and the luminaire grid 31, this is for the operation of the Fluorescent lamp 29 required ballast 40 housed.
  • the ballast 40 is located essentially in the interior of the profile 13, where there is sufficient space to accommodate the ballast.
  • Other components or a counterweight to the ballast can be accommodated in the interior of the other sheet metal profile 14.
  • FIG. 6 shows two luminaire housings 10 which are placed against one another at the end to form a light band and which are suspended at their mutually opposite ends on a common pendulum tube 38.
  • the gap between the inclined surfaces 18 of the end profiles 15 is filled by a triangular adapter 41 in side view, to which the pendulum tube 38 is attached.
  • the adapter 41 is in turn attached to the frame of the two lamp housings 10.
  • the attachment 12 of the lamp housing 10 is fastened directly under the ceiling, the top wall 26 touching the ceiling.
  • the inclined surfaces 27 of the attachment can be translucent overall or have translucent windows in order to provide ceiling lighting despite direct ceiling mounting.
  • the lateral boundary walls of the attachment 12 do not have to be designed as inclined surfaces 27, but these boundary surfaces can also protrude vertically. It is only important that these lateral boundary surfaces spring back against those of the frame and are part of an attachment which is subsequently attached to the frame 11.
  • the luminaire housing 10 - as in FIG. 1 - is fastened to the ceiling with spacers 42. These spacers are mounted on the top 12.
