Abstract

Lighting fixture including a light-transmitting lighting tube in which a plurality of series-connected miniature light bulbs are disposed and whose ends are provided with current connections in the form of female connectors which have an interior, centrally located, electrically conductive plug-in contact, so as to contact, when the lighting fixture is mounted, male connectors disposed in a holding head and connected with an electrical lead, the fixture further including a profiled connecting member which has a cross section in the shape of a circle segment and which, in the mounted state of the lighting fixture, is arranged so as to be rotatable about the lighting tube. The holding heads (2a, 2b) can be inserted into the ends of the profiled connecting member (3) and can be connected in a form-locking manner with the profiled connecting member (3) by rotating the profiled connecting member (3) and/or the holding heads (2a, 2b).

Claims10

Dependent claims

A lighting fixture comprising:

(a) two opposing holding heads;
(b) a female electrical connector disposed in the interior of each of the holding heads, the holding heads being positioned such that said female connectors face one another;
(c) a rigid lighting tube containing a plurality of series-connected miniature light bulbs, said lighting tube being disposed between said respective holding heads;
(d) a male electrical connector disposed on respective terminal ends of said lighting tube, each of said male connectors being electrically connected to one of said female connectors;
and
(e) a profiled connecting member having an arc-shaped cross-section and a gap, said profiled connecting member being disposed on each of said respective holding heads in a form-locking manner coaxially on the lighting tube, the profiled connecting member being rotatable about said lighting tube relative to said holding heads, whereby light only emits from the lighting fixture through the gap in the profiled connection member and the rotation of the profiled connection member controls the angle of illumination from the lighting fixture.
