Abstract:
A lamp bulb having an output adjusted for a desired application, the lamp bulb comprising:a) an envelope for containing a fill material under pressure, said envelope is transparent to ultraviolet radiation;b) a fill material, said fill material contained within said envelope and comprising individual constituents capable of forming at least two dissimilar excimer species, at least one of said individual constituents having a partial pressure ratio greater than the other of said individual constituents in an amount at least greater than about 0.05 to about 25 to provide a total fill pressure within said envelope no less than about 750 Torr at room temperature whereby upon energizing of said fill containing envelope in an amount sufficient to cause formation of said at least two dissimilar excimer species, the intensity of the radiation resultant therefrom is increased, the increase in radiation intensity is a function of the partial pressure ratio of said at least one of said individual constituents.
