EFFECT OF LED LIGHTING IN ELECTRICITY CONSUMPTION OF NORWAY

This paper discusses advantages and drawbacks of having two supply systems in a household, one conventional and one with low voltage that feeds LED lighting and information flow systems. The technical and economical aspects are discussed. A separate 36 V system can be used for DC distribution. The two systems can be connected via a converter to secure power quality. Merely exchanging incandescent bulbs with LED will not be feasible for such a system. However, it will be easier to integrate local alternative energy sources and trade energy to get a better economy. The advantages of energy trading are not studied in this paper.
