Definitions
- the invention relates to a low-voltage lighting device, with a pair of busbars laid in parallel and a pantograph slide that is displaceably guided on the pair of busbars and that isolates the current flow between the two busbars and a pivotable holder for one on the two by this insulation electrically separate carriage parts from a lamp holder or the like.
- a low-voltage lighting device which has a block-shaped current collector which is displaceably fitted on the pair of busbars and which has a receiving trough and a magnet for receiving a lamp with a spherical housing.
- the power connection between the pick-up carriage and the lamp must be closed by means of a separate cable, and the mounting of the lamp via magnetic cranes remains rather unsafe because of the electromagnetic fields which are often caused by the high current strengths of the low-voltage systems.
- the ball housing can be freely pivoted within the receiving trough, the possible lighting area is considerably restricted by the current collector block itself.
- the invention is therefore based on the object of eliminating these deficiencies and of creating a low-voltage lighting device of the type described at the outset, which is characterized by its space-saving, compact design, its robustness and functional reliability and, above all, by its freedom of pivoting and its all-round luminance distinguished area.
- the pick-up carriage consists of two pick-up devices sitting on the rails. and a holder between the pick-up heads rotatably mounted about a transverse axis normal to the carriage guide direction, the mount holder articulated electrically conductively on the pick-up heads being divided by an intermediate piece forming the insulation and itself being provided as a holder and power connection for the lamp holder.
- the lamp holder or the lamp is therefore seated directly on the holder which forms the freely rotatable middle part of the pick-up carriage and can thus be rotated between the pick-up heads as desired. No separate swivel arms and no wire connections are required, and a compact, stable lighting device is created in the smallest space.
- the holder for holding the lamp holder has a holding arm which is rotatable about a normal axis relative to the holder axis of rotation between the one holder part and a holding bracket attached in a conductive manner to the other holder part, whereby the receptacle arm, which is supported on both ends in an electrically conductive manner, is divided by an insulating intermediate piece, like the lampholder carrier, and in turn receives the lamp holder.
- the space requirement remains minimal and the self-conducting support and arm parts guarantee the wireless power connection to the power rails and ensure trouble-free, long-lasting operation.
- the mount support and, if appropriate, the receiving arm each consist of two metal bushings, which are fitted on both sides of the disc-shaped intermediate piece forming a plug, the result is a simple, low-cost construction which is optimally suited for fulfilling on the one hand its insulating and on the other hand its current-carrying tasks is.
- the plug poles protrude radially inwards through the
- these plug poles can be used at the same time to fix the intermediate piece with respect to the metal sleeves, which further simplifies the construction.
- the metal bushings with an end-side bearing bore can be plugged onto a metal bearing pin inserted in the supporting part and rotatably mounted between the supporting part and a bolt head via a for the rotational mounting of the mount carrier or the receiving arm metal spring be tensioned.
- FIG. 1 shows a low-voltage lighting device according to the invention
- FIGS. 2 and 3 show two exemplary embodiments of the pick-up carriage of this lighting device in the partially cut diagram of different scales.
- a current collector chute On a busbar pair 1, which is connected to a low-voltage power source in a manner not shown, which can be laid parallel to one another and insulated from one another in any position and direction via busbar supports 2, is a current collector chute
- the customer chute 3 has a holder 7 for the lamp holder of a low-voltage lamp L, which is rotatably mounted between the holder heads 4 about a transverse axis A normal to the guide bores 6, which holder is in turn subdivided by an insulating intermediate piece 8, the holder holder
- the holder 7 can now directly form a holder and holder for the low-voltage lamp 11, for which purpose a pair of plug-in poles 12 are inserted on both sides of the intermediate piece 8 into the metal bushings 7a, 7b of the holder 7, which plug-in poles 12 simultaneously Securing the cohesion of the mount carrier 7 protrude through the metal bushings 7a, 7b and engage in the plug pins 8a of the intermediate piece 8. Because the plug poles
- the mount carrier 7 can be equipped with a receiving arm 13 which can be rotated about a normal axis B to the transverse axis A between the one metal bushing 7b or a saddle-shaped one which can be fitted onto the metal bushing 7b Extension piece 7c of the mounting bracket 7 and a metal holding bracket 14 inserted into the other metal sleeve 7a and is similar to the mounting bracket 7 made of two metal sleeves 13a, 13b and an insulating intermediate piece 15 composed.
- the plug-in pole pair 12 forms the lamp holder, the plug-in poles 12 in turn projecting into the interior of the metal sleeves 13a, 13b and into the plug pins 15a of the intermediate piece 15 engage.
- the result is a lighting device, the lamp of which is not only longitudinally displaceable along the pair of rails 1 and pivotable about the transverse axis A, but also can also be rotated about a normal axis B, so that practically a usable lighting area is available.
