It is a problem in the field of light transmission systems to use unbreakable heat sensitive light guides such as plastic optical fibers, with a high thermal output light source. The heat sensitive light guide is damaged by the thermal output of the light source when placed in close proximity thereto. The improved light transmission apparatus uses heat sensitive plastic optical fibers as the primary light guide and uses a heat resistant interface to couple the plastic optical fibers to the light source. In the preferred embodiment, this interface is an optically conductive media that has high thermal attenuation and is interposed between the high thermal output light source and the heat sensitive plastic optical fibers. This interface can be a short length of glass optical fiber light guide as is used in the prior art.
