The first two phases of this program developed a lighting system that improved the system efficacy from 46 lm/w to 58 lm/w. In addition, the a power factor of 90% was attained which reduced the supply current by 46% as well as reducing the harmonic content below 3%. This system is being demonstrated on board a ship for final acceptance, and is expected to be employed on newly constructed ships. Phase 3 of this program explores the development of a still more efficient lighting system, in which an efficacy of 80 lm/w is the target. The system is a centralized system in which the 115 volt a.c. is distributed to one or more site on board ship and converted to a d.c. voltage. The d.c. is distributed on to a large group of lamps. At each lamp there will be an oscillator that converts the d.c. to a high frequency a.c. voltage that drives the lamp. This report is an analysis of the rectifying circuit, its efficiency and an estimated cost. 1 fig., 5 tabs.
