ABSTRACT:
Lighting fixtures and lighting system and method for illuminating optical fibers and surrounding environment incorporate light sources into separate weather-resistant housings that provide improved air flow for cooling the internal light source, and include provisions for illuminating lengths of optical fibers by separate spaced light sources with synchronized sequences of interposed color filters to promote uniform color illumination of lengths of optical fibers by the separate fixtures. Spurious light flux from the light source within the housing that is not focused on ends of optical fibers emanates from a weather-resistant globe on the fixture through a baffle that controls the intensity and distribution of illuminating flux through the globe, and that confines the flow of cooling air within the housing for more efficient cooling of the light source within the housing.
