Abstract
In a mercury-containing arc discharge device for converting electrical energy into resonance radiation, the isotopic distribution of the mercury in the device is altered from that of natural mercury so as to reduce imprisonment time of resonance radiation and thereby increase the efficiency of conversion of electrical energy into resonance radiation.
Claims7
A mercury-containing arc discharge device for converting electrical energy into resonance radiation, the Hg.sup.196 content of the mercury within the device being greater than that in natural mercury in order to increase the efficiency of converting said electrical energy into said resonance radiation.
A mercury-containing arc discharge device for converting electrical energy into resonance radiation, the isotopic distribution of the mercury being altered from that of natural mercury so as to reduce imprisonment time of resonance radiation, thereby increasing the efficiency of converting electrical energy into resonance radiation.
In a fluorescent lamp of the type comprising an envelope having an electrode at each end, a phosphor coating on the envelope, and containing a fill including mercury and an inert gas, the improvement comprising the isotopic distribution of the mercury being altered from that of naturally-occurring mercury so as to improve lamp efficiency.
