Real Energy Saving Fluorescent Lamps

Abstract

Real energy savers are lamps with an essentially higher luminous efficacy than existing light sources used for domestic and commercial applications. An ideal lamp should combine the advantages of incandescent and fluorescent lamps. By appropriate design, based on low pressure sodium vapor discharge with a recombination structure and the use of narrow band phosphors of outstanding quality, it is possible to make an efficient small fluorescent lamp-ballast unit with good color rendering properties. In the commercial lighting area new lamps with efficacies of 90 to 100 lumens per watt and good color rendering properties will become available by using these narrow band phosphors together with a change in lamp design. Compared with the present standard lamps one can now maintain the illumination level with lower annual costs and lower energy consumption.
