Abstract
A lighting fixture is disclosed which utilizes liquid cooling to remove heat generated by the lighting devices mounted in the fixture. The lighting fixture is removably attachable to a previously installed cooling pipe by a wedge or cam rod which engages the surface of the cooling pipe and the walls of a groove in the fixture in which the cooling pipe is disposed. The reactors and other necessary equipment for the lighting devices are mounted in a channel shaped structure which is in heat transfer relationship with the cooling pipe so as to remove heat therefrom.
Claims5
A box or channel-shaped lighting fixture, having an internal cooling body for heat conducting contact with a straight liquid carrying cooling tube arranged in parallel with and between two lighting tubes or rows of lighting tubes, comprising;
- two metal plate channels (I, II) forming the lighting fixture (1) surrounding both lighting tubes (2), said channels being formed at their junction in the upper portion thereof with an upwardly open groove (18) for engaging the cooling tube directly below the roof (1') of the fixture;
- a downwardly extending, double partition wall (5) located between the lighting tubes, and contacting said channels to transfer heat thereto, said double separating wall (5) forming a downwardly open channel which is located below said groove (18) and wherein reactors of the lighting tubes (2) are mounted, which reactors are fixed in heat conducting manner within the channel.
