Real Cathode and Anode of Internal DC Electric Circuit in FL Lamp

FL lamps are operated with the coexistence of disparate external and internal electric circuits. FL lamps light up with the internal electric circuit, in which cathode and anode are separately, but simultaneously, formed by volume of glow or corona light in Ar gas space at both ends of FL lamps, under the electric field from electrodes of the external electric circuit. The developed coil-EEFL lamps light up under AC and DC external driving circuits. Under the AC driving circuit, only Cphos involve in the WAC that is less than one tenth of the WAC of the HCFL lamps. Under the DC driving circuit, WDC = 0. The feature of FL lamps is the superconductive vacuum at above room temperatures, giving rise to astronomical quantum efficiency [ηq = 1013 visible photons (m3, s)-1 per one moving electron]. Each FL lamp is operated with 1012 electrons per second. Consequently, the coilEEFL lamps steadily emit the 1025 visible photons (m3, s-1). The LED lamp has only ηq < 1.0. All components of the coil-EEFL lamps reserve in the operation, resulting in the life > 106 hours. The developed coil-EEFL lamps surely contribute to the COP project of UN with the reduction of the electric power > 30 % on the world.
