Various light sources were evaluated for use in a fiber optic lighting system for mining machines. It was determined that a metal halide arc lamp was best because of its resistance to damage from shock and vibration and the high luminance of the arc. The new lighting concept offers signi ficant advantages over convent; onal systems i n the areas o f both safety and 1 ong- term mai ntenance costs. Fiber optic technology is centered around the transmission of information as light pulses through strands of glass or plastic fibers. The state, throughput, and identification of an optical fiber can be easily checked with fiber testers by coupling highly visible laser light into the optical fiber.
