Definitions

  • the invention relates to a surface or wall lamp referred to in the preamble of claim 1.
  • Art. A lamp of this kind is in the US 2004/0037068 described.
  • the invention is based on the object for the US2004 / 0037068 well - known wall or ceiling lamp to create a surface mounted luminaire, with which an optimal workplace and room lighting is possible and on the one hand easy to assemble and on the other to a high degree service - friendly.
  • the known luminaire consists essentially of an elongated housing of approximately triangular cross-section. Inside the housing, a lamp is arranged, the light is emitted with the help of parallel to the lamp extending reflectors and angularly arranged mutually apertures on the workplace directly or indirectly in the direction of the ceiling.
  • the overall structure of the luminaire 1 according to the invention is shown in perspective view Fig. 1 to recognize.
  • the luminaire housing consists essentially of a rear wall 30, to which perpendicular to this standing with the aid of countersunk screws 16 side parts 10 and 20 are screwed, which at the front over a profiled rail 40 with each other are connected. This is also connected with countersunk screws 16 with the side parts 10 and 20.
  • the recording of the countersunk screws 16 serving sink holes 11 are, as above all Fig. 3a can recognize, provided with so-called Kratznocken 12, which ablate when adhering the countersunk screw adhering to this varnish and thus ensure a good electrical connection between the side members 10, the countersunk screws 16 and connected to these rear wall 30 and the front rail 40.
  • a fluorescent lamp 2 which is inserted in mounted on the side parts 10 and 20 lamp sockets 3.
  • the lamp is covered by transparent panels, of which in Fig. 1 only the upwardly opened aperture 50 is shown.
  • the lamp connecting cable 91 For electrical connection of the lamp connecting cable 91 are provided within the lamp housing between the rear wall 30 and reflector 61a, which are located at the ends plug 92 and sockets 93 can be seen, which passed through provided in the side walls 10 and 20 through openings 18 and 18 ' can be. Furthermore, 10 and 20 associated locking pins 15 and latching openings 17 are provided in the side parts, which, as explained below, serve the alignment and locking of the arranged in a row lamp elements.
  • back wall keyhole-shaped apertures 31 are provided in series next to each other.
  • the most important measures for the design of the lamp according to the invention relate to the light distribution and light guidance, as the latter with the cross section according to Fig. 2 are illustrated, in which the light beams generated by the lamp 2 for generating the indirect light A, for generating the direct light B and the side light C are indicated schematically.
  • symbolized here light guide is made possible by the special design of the rear reflector with the reflector surfaces 61a and 61b and the front reflector with the reflector surfaces 62a, 62b and 62c and the aperture 50 and 70th
  • the reflector surfaces 61a and 62a delimit a lower chamber 63 opening downwards in a funnel shape, the reflector surfaces 61b, 62b and 62c delimiting an upper chamber 64 which opens upwards in a funnel-shaped manner.
  • the lower chamber 63 is covered by a lower aperture 70 with a groove-like structure.
  • the reflector surfaces 61a and 62a, together with the grooved lower panel 70, cause the light generated by the lamp 2 to illuminate the workstation to be deflected mainly vertically downwards in the direction B, while laterally exiting light in the direction C is largely suppressed, resulting in an extremely good glare-free leads.
  • the upper chamber 64 is covered by a frosted aperture 50.
  • the light emitted upward from the lamp 20 becomes reflected by the reflector surfaces 61b, 62b and 62c and diffused by means of the matted aperture 50 to a greater extent than with the lower aperture 70, whereby an emerging in the direction A, reflected from the ceiling indirect light is generated.
  • the reflector surfaces 61a and 61b and the reflector surfaces 62a, 62b and 62c are made in one piece.
  • the upper panel 50 is pivotally mounted with a located at the rear edge 51, bent down lip 51a in a provided on the upper edge of the rear wall groove 35.
  • the upper panel 50 as with Fig. 4a is shown, are swung upwards.
  • A likewise at the rear edge of the upper panel 50 parallel to the lip 51 a extending front lip 51 b, which abuts the groove 35 delimiting the front wall portion 35 a of the rear wall 30, prevents the upper panel 50 is released during folding.
  • the rear wall 30 runs upwards into an extension 35c which forms a stop for the panel 50, the function of which mainly consists of Fig. 7 is apparent.
  • This design allows the bezel 50 to be locked in the folded up position so that the service technician has both hands free for lamp replacement, repair or cleaning.
  • the closed upper panel 50 engages with a downwardly directed elastically resilient lip 52 for locking in a groove 42 of the rail 40 a.
  • the upper panel 50 and the rail 40 are dimensioned so that when the shutter 50 is closed, its surface is flush with the surface of the rail 40, so that there is only a narrow gap between the adjacent edges of the panel 50 and rail 40. This accidental opening of the aperture is largely prevented, as to open a tool, for. As an inserted into the gap screwdriver is required.
  • the diaphragm 70 on both sides against the diaphragm thickness tapered edges 71 which is at one end in a groove 32 of the profiled rear wall 30 and the other end in a groove 41 of the profiled rail 40 releasably inserted.
  • the distance between the mutually facing edges 32 a of the rear wall 30 and 41a of the rail 40 is less than the width of the inserted aperture 70, the distance of the bottoms 41b of the groove 41 and 32b of the groove 32, however, greater than the width of the lower aperture 70, whereby on the one hand a slight insertion and holding the aperture 70 secured is.
  • a fixing pin 13 which, as above all Fig. 3 shows, is provided on the side part 10.
  • the edges 71 and 72 of the lower panel 70 and the aperture are sized so that when inserted aperture 70 results in a smooth transition.
  • a number of keyhole-shaped openings 31 are provided in the rear wall 30 of the lamp 1, which already in connection with Fig. 1 are mentioned.
  • Their special training shows the perspective view according to Fig. 5a .
  • the lamp 1 is placed during assembly on the supply channel 80 located threaded pins 81 which pass through the keyhole-shaped openings 31.
  • the screwed onto the grub screws 81 nuts, preferably locking nuts 33, are attracted.
  • the opening 31 provided on the slot 31a allows alignment of the lamp 1 in the vertical direction.
  • an upwardly cranked tab 82 is provided at the lower end of the supply channel 80, which engages in a receiving groove 36 of the rear wall 30.
  • a spring-loaded locking pin 15' is provided, which in an associated with this, z. Tie FIGS. 1 and 3 recognizable, latching opening 17 engages. When disassembling this locking pin 15 'is to be solved.
  • the spaces between the rear walls 30, 30 'and the reflector surfaces 61a and 61a' are dimensioned such that, after disconnecting the connection cables 91 and 91 ', these together with their sockets 93 and the plugs 91' are easily stowed behind the reflectors 61a and 61a ' can.
