Definitions

  • the invention relates to a lamp according to the preamble of claim 1.
  • Luminaires according to the preamble of the first claim are used for example as table, wall or ceiling lights, see e.g. FR-A-2 576 668. They correspond to protection class II.
  • the advantages of the invention lie in the uncomplicated and yet safe handling.
  • the arrangement of the socket on a flexible elastic means the additional advantage that lights that are equipped with reflectors of different heights (spot, flood version) can use the same sockets and fittings.
  • the arrangement of the socket according to the invention also allows maximum heat dissipation, since the socket is freely accessible.
  • the flexible mounting of the holder with the aid of an elastic means makes the holder captive and, in principle, at the same time allows a very simple fastening of the reflector in the opening of the holding part due to the spring force directed towards the holding part.
  • a single latching lug located at the opening is sufficient for securely fastening the reflector in cooperation with the elastic holding strap.
  • the tether with its channels ensures strain relief for the electrical leads that run in the tether.
  • the flexible mounting of the socket takes into account the known high tolerances of the lamp base with the simplest of means and allows simple and secure contacting by means of a screw closure.
  • the holding part can be swiveled continuously over a range of 98 °.
  • the weight of high temperature resistant Plastic-made socket is very small (approx. 50 g) and the socket is very small, which is made possible by the new fastening technology.
  • the electrical power supply takes place via a mains cable 13 with a plug, which is led into the interior of the cover 12 and from there reaches the interior of the pot 10 through a central opening of the circular disk with extension piece 14.
  • a circuit board 16 is mounted, which carries the electrical components 17 used for the power supply of the lamp, including in particular a transformer.
  • a possible operating circuit that makes the lamp suitable for dimmer operation is e.g. described in DE-OS 36 35 109.
  • the hinge 7 itself is formed from a long middle piece 19, which is flanked by two shorter end pieces 20, 21.
  • the middle piece 19 is as cylindrical tube section 28 is formed along one side of the holding part 4 and open on both sides.
  • a collar 22 is pulled up inside, which is fitted into a circular groove 23 of the first end piece 20.
  • the first end piece 20 is a loose tube section which is closed on one side and on which a slotted guide channel 24 is formed on the outside, parallel to the axis, for plugging onto a rail 25 formed on the base part 8.
  • the inner wall of the groove 23 is extended to a stop for an inner sleeve 26 inserted in the middle piece, which covers a side slot through which the retaining band 34 (see below) is inserted into the middle piece.
  • the electrical feed lines 18 are guided into the center piece 19 via the guide channel 24.
  • the second end piece 21 is flush with the pipe section 28.
  • the second end piece 21 is in turn formed tangentially on the base part 8.
  • the connection between the middle piece 19 and the second end piece 21 takes place via a conical end region 29, which is molded onto the middle piece (FIG. 3b).
  • the tube section 28 has a constant outer diameter
  • the inner diameter increases towards the collar 22, so that, conversely, the wall thickness increases towards the end region 29.
  • part of the wall thickness is removed on the outside, in such a way that the wall thickness in the end region 29 remains constant and the end region 29 forms a thin conical tube.
  • This conical end region 29 is also slotted and therefore resilient overall. It engages in the second end part 21 over its entire length.
  • a transverse wall 29b designed with a central gap
  • a chamber 30 in which a spiral spring 31 is clamped in the end region 29 transversely to the hinge axis (and the longitudinal axis of the end piece).
  • the spreading by the spring 31 has the effect that the end region in the interior of the second end piece 21 just lies so that a continuous adjustment of the entire hinge is possible.
  • the center piece 19 has a rectangular opening 32 facing the holding part 4, into which the bead-like widened end 3 of an elastic holding band 34 is clamped.
  • the retaining band 34 (FIGS. 4 and 5), which is ribbed transversely to its broad sides (in order to increase the elasticity), is equipped with two longitudinal channels 35 through which the electrical leads are guided from the center piece 19.
  • the other, also bead-widened end 36 of the tether is attached to the underside of the socket 5 in a rectangular opening.
  • the power supply lines 18 are led out of the holding band and bent laterally towards the screws 6 and soldered to metal contact tubes 37, in which the screws 6 are captive but loosely guided.
  • the two screws 6 and contact tube 37 are embedded in the rear wall 38 of the socket, which is also shielded with a plastic plate 40 for better thermal insulation.
  • the plate 40 is held in the socket 5 by means of rails 41.
  • the retaining band 34 is curved from the center piece 19 to the socket 5 to form a quarter circle, so that the socket 5, when screwed to the base, presses the reflector 2 including the lamp 1 into the circular opening of the holding part 4.
  • the quarter circle is somewhat reduced by the bevel in which the rectangular opening on the center piece is oriented with respect to the holding part, which reinforces the pressing spring action of the holding band.
  • three locking lugs 39 are distributed around the opening of the holding part in this exemplary embodiment (FIG. 2). In principle, however, a latch would already be sufficient.
  • the base 27 of the lamp-reflector unit is designed as a ceramic base (base stone) known per se, similar to that described in FIG. 2 of EP-PS 121 819, the external power supply lines of the lamp being held by contact tabs which are arranged in a central rectangular shape Extend the opening of the base stone.
  • the bent ends of the contact lugs are used as guides for the edge strips 5a in the luminaire presented here Put on the version 5 used.
  • the threaded holes of the contact lugs cooperate with the knurled screws of the socket 5, so that the socket 5 is simultaneously held by this arrangement and the intimate one useful for dimming Contact (by placing the contact tubes on the contact lugs and tightening the knurled screws).
