Abstract: A method of operating cold cathode in discharge lamps, including discharge lamps operating with a dielectrically hindered discharge that include two electroconducive electrodes facing each other between which a ferro-electric material is sandwiched. At least one of the electrodes presents one or more openings. When the cathode is operating, a voltage of quickly alternating polarity is applied to both electrodes, thereby freeing electrons on the surface of the ferro-electric material. The working voltage of the discharge lamp causes an acceleration of said electrons, which pass through the openings towards the anode and are used for igniting the discharge lamp and keeping it in an operating mode.

Abstract: A cold-cathode, plasma discharge modulator switch is disclosed. A crossed-field discharge plasma supplied charge carriers for the switch. A dc magnetic field is employed to provide a highly localized cusp magnetic field near the cathode, so that gas ionization occurs primarily in the cathode-source grid gap. The region between the cathode and anode is filled with a relatively low pressure gas. A highly transparent control grid with small apertures is closely spaced from the anode. The switch is closed through application of positive potential (relative to the plasma) to the control grid, and opened through application of negative potential relative to the plasma to the control grid. The application of negative potential to the control grid creates an ion sheath around the control grid which permits plasma cut-off to the anode region provided the sheath size is larger than the control grid aperture radius. Upon plasma cut-off, the switch current is interrupted as the remaining plasma in the control grid-anode gap decays. Low pressure operation insures that ionization cannot sustain the plasma in the narrow, isolated control grid-anode gap.

The mixture is especially beneficial for use in a color phosphor gas discharge display/memory device because the mixture substantially lowers peak gas discharge currents while providing phosphor stimulation. The xenon-based composition consists essentially of about 95 to 100 percent atoms of xenon and about 5 to 0 percent atoms of another component, particularly one or more selected from neon, krypton, nitrogen, helium, and mercury.

Abstract: A discharge lamp lighting device includes a lamp current control portion that generates, in synchronization with an input video signal, a control signal for controlling polarity reversal of an AC current with a steady-state lighting frequency and an AC current with a low frequency, and a lamp driving portion that drives the discharge lamp based on the control signal that is output by the lamp current control portion. The lamp current control portion generates a control signal for a brightness reduction waveform with timing corresponding to polarity reversal of the AC current with the steady-state lighting frequency, and the lamp driving portion inserts a current reduction waveform into the AC current with the low frequency by decreasing a voltage applied to the discharge lamp based on the control signal for the brightness reduction waveform. It is possible to reduce flicker that could be perceived due to insertion of a period without a reduction of the projection light amount (a period without a polarity reversal at the low frequency) during repeated reductions of the projection light amount occurring at intervals of polarity reversal of the steady-state lighting frequency.
