Definitions

  • the invention relates to a linear luminaire, consisting of a luminaire housing, a mirror arrangement which can be inserted into the light outlet opening of the luminaire housing and, in the region of the end walls of the luminaire housing, both horizontally and vertically adjustable sockets for holding and contacting at least one fluorescent tube.
  • the adjustable arrangement of the sockets in such a way that they are each fastened to an adjustable or pivotable lever in the area of the housing end wall represents a relatively great technical outlay.
  • the literature reference DE-OS 22 52 991 shows, there is the possibility of to fix the socket at predetermined different locations on the front wall of the lamp housing by choosing that partially cut out in the front wall at the specified locations Sheet metal tabs are provided. Depending on the need, these metal tabs can be bent up to hold a frame in a predetermined position and the frames can be anchored therein. Such an attachment of the sockets makes it extremely difficult to subsequently change the position and also requires special tools for this.
  • the object of the invention is to provide a further solution for a lampholder adjustment for a long field luminaire of the type described in the introduction, which solution requires a minimum of additional technical effort, while ensuring an adjustment which can be carried out quickly and without tools.
  • the invention is based on the finding that the socket to be fastened in a luminaire housing generally makes use of a holder and is therefore possible by suitable design of the holder, on the one hand by a displaceable fastening of the holder on the housing base of the luminaire housing and on the other hand the adjustable arrangement the holder in the holder, the desired adjustment in the horizontal and vertical direction can be easily repeated without using special tools.
  • FIG. 1 shows in cross section a box-shaped luminaire housing 1 with side longitudinal walls 1.1 and a housing base 1.2, as is usually provided for a linear luminaire to be installed in a false ceiling.
  • a linear luminaire to be installed in a false ceiling.
  • different mirror arrangements can be used from the side of the light exit opening in the luminaire housing 1.
  • the mirror arrangement shown in Fig. 1 consists of two parabolically curved side mirrors 2 and 3 and transversely arranged, indicated only in broken lines, mirror louvres 4.
  • the fluorescent tube 5 can in its version to change the beam characteristic vertically down into the the circle 5.1 drawn in a broken line can be adjusted.
  • the broken circle 5.2 indicates a possible horizontal adjustment of the fluorescent tube 5, which, however, is out of the question for the mirror arrangement shown in FIG. 1.
  • FIG. 2 A linear luminaire equipped with such a lampholder adjustment is shown in longitudinal section in FIG. 2.
  • Each of the sockets 6, in which the fluorescent tube 5 is inserted, is assigned a holder 7, which has a vertical frame 7.1 accommodating the socket 6 parallel to the end wall 1.2 and a horizontally oriented base plate 7.2 parallel to the housing base 2.
  • the holder 7 is with its frame 7.1, each in the immediate vicinity of the end wall 1.3 of the lamp housing 1 with its base plate 7.2 attached to the housing base 1.2.
  • the base plate 7.2 has two clamping feet 7.21 on its underside in the longitudinal direction one behind the other, with which they engage in a force-locking manner in two sliding slots 1.21 shown in FIG. 7 and running parallel to the end walls 1.3.
  • the socket 6 in the luminaire housing 1 is in the position indicated by the fluorescent tube 5 according to FIG. 1.
  • the socket which is adjustable in the frame 7.1 of the holder 7 in the vertical direction, has on its outside two mutually opposite retaining webs 6.1, with which it engages in one of the pairs of guide grooves 7.11 and 7.12 of the frame 7.1 according to its desired vertical position.
  • the socket 6 has the smallest distance from the base plate 7.2 on the housing base 1.2 of the lamp housing 1 and engages with its retaining webs 6.1 in the groove guide pair 7.12 of the frame 7.1.
  • FIG. 5 corresponds to that of FIG. 4 with the difference that now the socket 6 in its holder 7 is moved in the position parallel to the end walls 1.3 in the direction of the arrow to the right in the sliding slots 1.21 in the housing base 1.2, which is indicated in Fig. 1 by the circle 5.2.
  • the foot shows how the section of FIG. 5 marked by a circle and shown in FIG. 6 and the view of this section shown in FIG. 7 show plate 7.2 on its underside on both sides in the amount of a clamping foot 7.21 additionally a latching cam 7.22, the respective distance a to the associated clamping foot 7.21 shown in FIG. 7 is chosen equal to the maximum displacement of the holder 7 in the displacement slots 2.21. In this way it is achieved that when the holder 7 is horizontally displaced in the sliding slots 2.21 until the stop of the clamping feet 7.21 on one of the two ends of the sliding slots, the latching cams associated with the clamping feet 7.21 engage in the sliding slots 1.21 on the other of the two ends. In the illustration according to FIGS. 6 and 7, it is the two left latching cams 7.22 which additionally engage in the displacement slots 1.21 when the holder 7 is in the shifted position indicated.
  • the described linear luminaire can be used in various configurations, both as a pendant luminaire and as a recessed ceiling luminaire indoors.
