<p>An adjustable lamp holder for low-voltage lamps comprises conducting clamping pieces 9, 10 arranged parallel to one another and capable of being braced by a screwed connection (joint) 4, 5; 6, 7; 8, and which can be mounted on a busbar (conductor bar) in a manner of pincers. The busbar is formed by conductors 1, 2 held at a spacing from one another by means of spacers 3. The clamping pieces 9, 10 further embrace a ball 11 which is split into two halves 16, 17 by an insulating disc (washer) 18. Each of the halves 16, 17 bears a contact piece, e.g. a bore (hole) 21, 22 for connecting a low- voltage lamp 23. By loosening the screwed connection 4, 5; 6, 7; 8, the lamp holder can be displaced longitudinally on the busbar, and the rotary position of the ball 11 can simultaneously be adjusted between the clamping pieces 9, 10. <IMAGE></p> |
