Abstract
It has been shown that interesting new possibilities for lighting with fluorescent lamps appear when a tenuous glass-wool recombination structure is introduced into the discharge space. Now, the technological feasibility of the structure concept for application in fluorescent lamps is demonstrated by 1) the possibility of mechanical and reproducible filling of lamps with a wool structure, and 2) the manufacture, and the investigation of the effects, of two alternative structures. Moreover, the structure-inherent effects in low-pressure sodium lamps are discussed.
