  • Fluorescent light source based on a phosphor excited by a molecular discharge
    Patent number: 4937503
    Abstract: A fluorescent light source based on a phosphor excited by a molecular discharge is described. The fluorescent light source comprises a capacitively coupled compact fluorescent lamp coated with a manganese doped magnesium aluminate phosphor on the inside surface of the lamp envelope. The compact fluorscent lamp produces a plasma which emits 206 nm radiation from the molecular discharge of the iodine containing molecular vapors and inert gas fill which in turn excites the phosphor to emit visible light.
