The lifetime of a fluorescent lamp mainly depends on the loss of Ba atoms from its electrode, i.e. the rate of Ba atoms loss controls the lifetime of the lamp. The mechanism of the loss has not been clarified yet sufficiently. We have investigated relationship between electrode temperature distributions and characteristics of Ba atom emission in a fluorescent lamp which are measured by using bl...
The prevalence of electric discharge illumination has led us to consider ways to use discharge lamps for communication. This paper describes an optical transceiver system which transmits by modulating the lamp arc. The prototype power electronic lamp ballast uses a pulse frequency modulation scheme which ensures no perceptible flicker.
Full-spectrum fluorescent lighting (FSFL) has been credited with causing dramatic improvements in vision, perception and cognitive performance as compared with other fluorescent lamp types. These effects are hypothesized to occur because of similarity between FSFL emissions and daylight, which is said to have evolutionary superiority over other light sources. This review, covering 1945-98, crit...
BACKGROUND Full-spectrum fluorescent lighting (FSFL) has been credited with causing dramatic beneficial effects on a wide variety of behaviours, mental health outcomes and physical health effects, as compared to other fluorescent lamp types. These effects are hypothesized to occur because of similarity between FSFL emissions and daylight, which is said to have evolutionary superiority over othe...
