A light directing, load bearing, thermally protective coupling for connecting a light conduit, such as a light pipe, to a light source includes a body member having a first end connected with the light source and a second end connected with the light pipe. The body member contains a longitudinal channel which extends from the first end to the second end and includes an inner surface defining the channel which directs light from the light source, through the coupling, to the light pipe. To reduce light loss, the inner surface is provided with a highly reflective finish. The coupling is formed of a thermally conductive metal which dissipates heat from the light source and has a length sufficient to produce a temperature drop which allows the light pipe to be connected with the coupling without damaging the light pipe. The first end of the coupling includes a lip portion which is connected with a gasket provided on a light source reflector cone, and the second end of the coupling can include a collar which interlocks with a mating collar provided on an adjacent light pipe. |
