Abstract

A low voltage lighting assembly which comprises a lamp holder, a pair of rigid electrically conductive arms, each arm having a lower end that passes through opposingly disposed apertures in the lamp holder in a manner so as to maintain electrical contact with a lamp socket disposed within the lamp holder, while said lamp holder is pivotable about the axis of the lower arms, each arm having an upper end with means to permit independent movement of an arm along one of a pair of spaced apart elongate electrical conductors and to be fixed in place to form electrical contact therewith. The conductors have means to connect to a suitable source of electric current, at a voltage of no more than about 24V. By pivoting the lamp holder about the axis of the lower arm ends, and moving each of the upper arm ends along the conductors, a lamp mounted in the holder may be positioned transversely with respect to the axis lying through the lower ends and longitudinally with respect to the conductors.

Claims

1. A lighting assembly for operation at no more than about 24 volts comprising a lamp holder, a pair of rigid electrically conductive arms, each arm having a lower end and an upper end, said lower ends being opposingly mounted on the lamp holder in electrical contact with a lamp socket disposed within the holder, in a manner such that the lamp mounted in said holder may be positioned axially about thereof, each upper end having means to permit independent movement along one of a pair of spaced apart elongate electrical conductors and to be fixed in place to form electrical contact therewith, each said conductor having means to connect to a source of electric current, and wherein movement of said amrms along said conductors permits a lamp mounted in said holder to be positioned transversely with respect to the axis lying through the lower ends and longitudinally with respect to the conductors.

2. A lighting assembly as in claim 1, wherein the conductors are rods disposed in parallel array between two opposing walls.

3. A lighting assembly as in claim 2, wherein each of the upper ends has disposed thereon a U shaped member, the opening of which is adapted to co-operate with the conductor and wherein a threaded portion of the U shaped member accepts a nut to secure said upper end on each conductor.

4. A lighting assembly as in claim 3, wherein the U shaped member is affixed to an upper end by a thread formed on a portion thereof and an internally threaded portion in said member.

5. A lighting assembly as in claim 4, wherein electrical contact is maintained between the socket and the lower end by disposing said lower end in a slot formed between the body of the lamp holder and the socket, and wherein a screw passed through said body acts to force the lower end into electrical contact with the socket and retain said lower end therein.

6. A lighting assembly as in claim 5, wherein the conductors are aluminium or brass rods.
