Abstract: A lighting system that includes a lamp and a control circuit configured to apply signals to the lamp in pulsed mode operation. The lamp may employ ferroelectric ceramic cathodes to enhance life of the lamp when used with the pulsed mode drive circuitry. The drive circuitry applies signals within a desired frequency range to lower input power while providing enhance output within a desired wavelength band, such as 365 nm to make use of an afterglow regime from an emissive medium within the lamp.

Abstract: A hybrid emitter exploits the electric field created by a rapidly depoled ferroelectric material. Combining the emission properties of a planar thin film diamond emitter with a ferroelectric alleviates the present technological problems associated with both types of emitters and provides a robust, extremely long life, high current density cathode of the type required by emerging microwave power generation, accelerator technology and display applications. This new hybrid emitter is easy to fabricate and not susceptible to the same failures which plague microstructure field emitter technology. Local electrode geometries and electric field are determined independently from those for optimum transport and brightness preservation. Due to the large amount of surface charge created on the ferroelectric, the emitted electrons have significant energy, thus eliminating the requirement for specialized phosphors in emissive flat-panel displays.

Abstract: A high intensity discharge lamp system includes an AC supply for a chamber within which a plasma conductor is created to generate light. In order to confine charged particles within the chamber and to inhibit migration and loss thereof, a DC circuit taps power from the AC supply and produces a DC potential which is applied to relatively large-surface components in the vicinity of the plasma chamber. Properly polarized, the large-surface components, such as a reflector and a conductive housing, refractor or door, produces electric fields which inhibit migration of the charged particles. The result is improved color and light output as well as increased lamp life.

Abstract: Disclosed is an electrical driving and recovery system for a high frequency environment. The recovery system can be applied to drive present day direct-current or alternating-current loads for better efficiency. It has a low-voltage source coupled to a vibrator, a transformer and a bridge-type rectifier to provide a high voltage pulsating signal to a first capacitor. Where a high-voltage source is otherwise available, it may be coupled directly to a bridge-type rectifier, causing a pulsating signal to the first capacitor. The first capacitor in turn is coupled to a high voltage anode of an electrical conversion switching element tube. The switching element tube also includes a low voltage anode which is connected to a voltage source by a commutator and a switching element tube. Mounted around the high voltage anode is a charge receiving plate which is coupled to an inductive load to transmit a high voltage discharge from the switching element tube to the load. Also coupled to the load is a second capacitor for storing the back EMF created by the collapsing electrical field of the load when the current to the load is blocked. The second capacitor is coupled to the voltage source. When adapted to present day direct-current or alternating-current devices the load could be a battery or capacitor to enhance the productivity of electrical energy.

Abstract: A high-pressure sodium lamp is connected to a d.c. power supply through a ballast, to operate it with a current containing a d.c. component. The relation between the ratio l/d of the inter-electrode distance l (mm) to the inner diameter d (mm) of the arc tube of the high-pressure sodium lamp and the sodium vapor pressure P.sub.Na (kPa) in the arc tube is maintained at P.sub.Na .gtoreq.6.0 (l/d-5.8), thus making it possible to operate the high-pressure sodium lamp with a current containing a d.c. component without causing a significant color separation which otherwise might be the result of cataphoresis.

Abstract: A high-coulomb transfer switch useful for high current pulse power supplies employs an inverse-pinch mechanism to sweep the arc current sheet over the electrodes. The inverse pinch currents are formed by a special electrode configuration wherein the inner electrode has the shape of a mushroom with the "cap" surrounding the "stem" so that the currents flowing in the electrode enclose the magnetic induction around the "stem". This results in repulsive forces on the outer currents in the "cap" causing the arc current sheet to rapidly move from the lip at the "cap" where the arc is initiated upward to the crown of the "cap" where occurs the final decay of the current. In the disclosed preferred embodiment, the inner, outer and return electrodes are generally cylindrical and placed coaxially. The switch can be operated under a vacuum or under a high pressure gas.

Abstract: High energy switching device utilizing a gas discharge tube with input and output electrodes connected electrically in series with a source and a load. A control element is connected to the input electrode, and a trigger signal is applied to the control element to initiate firing of the tube to pass energy from the source to the load. An electrostatic shield is disposed about the output electrode to prevent the tube from self firing in the absence of a trigger signal when the potential between the electrodes is below a predetermined level.
