Centralized high frequency supply system for lighting systems

Abstract

The cost of power generation is continuously increasing everywhere in the world. In Sri Lankan context this has an added effect as the low cost hydropower resources have been exhausted while the demand is continuously increasing at a rate of around 8%. however this effect can be diluted to some extent if proper Demand Side Management options arc utilized. One such option commonly and effectively used is the replacement of incandescent lamps through fluorescent lamps. For industrial and commercial lighting. the standard linear fluorescent tubes give the best efficacy at low cost. However for domestic applications and also for some commercial applications linear fluorescent tubes arc not aesthetically pleasing and thus compact fluorescent lamps arc widely used for such applications.
