Abstract:
The present invention provides a base socket that fits into incandescent fixtures and allows one or many "stick" type compact fluorescent lamps to be inserted. The fixture allows the user to insert as many CFL's as desired without changing or rearranging, in any way, the ballast. The ballast circuitry is designed for series or parallel electrical connections of the CFL's. When in series each socket has a bypassing microswitch that provides for electrical circuit continuity.
Abstract:
A glow discharge lamp includes a sealed lamp envelope containing a noble gas and mercury, a cathode and an anode disposed in the lamp envelope and an incandescent filament for emitting visible light for illumination immediately upon application of power and for emitting little or no visible light after a glow discharge is formed between the cathode and the anode. The filament, the cathode and the anode are electrically connected in series. The lamp envelope typically includes a phosphor coating for emission of visible light upon absorption of ultraviolet radiation from the glow discharge. An optional switch can be used for disconnecting the filament during steady state operation of the glow discharge lamp.
Abstract:
A low pressure discharge lamp, particularly a compact fluorescent lamp, having a plurality of constricting portions axially spaced apart and extending about the circular periphery of the envelope. The constricting portions, which include defined end segments projecting within the envelope, constrict the plasma discharge and spatially separate at least one of the discharge processes occurring within the plasma discharge and cause the separated process to take place in a different portion within the envelope so that the conditions for energy input and energy dissipation may be independently optimized.
Abstract:
A low pressure arc discharge tube having structural means located within the envelope for causing a positive shift in the volt-ampere characteristic curve of the arc discharge tube. The shift in the volt-ampere curve causes a decrease in the impedance necessary to stabilize and ballast the discharge.
Abstract:
A fluorescent lamp wherein magnetic field generating means (e.g., permanent magnets) are utilized to generate a static magnetic field across the respective electrode structures of the lamp such that maximum field strength is located at the electrode's filament. An increase in efficacy during operation has been observed.
Abstract:
A simple photoionization technique for enriching a particular isotope of mercury in a naturally-occurring mixture employing an isotopically pure radiation source separately optimized for 253.7 nm. and 404.7 nm. emission, respectively. A vessel is provided for containing the naturally occurring mercury. This vessel may be part of either a flow or closed system. The radiation source brings the isotope from the 6.sup.1 S.sub.0 ground state to the 6.sup.3 P.sub.1 state wherein the nitrogen gas deactivates the isotope to bring the isotope to the long-lived 6.sup.3 P.sub.0 state. Thereafter, the source optimized at 404.7 nm. brings the isotope to the 7.sup.3 S.sub.1 state. At this level the atom may be easily photoionized either by a laser or a powerful visible incoherent radiation source.
