Latest Patents
Ponsen's latest patents include innovative designs that enhance the operation of discharge lamps. One of his inventions is a discharge lamp operating circuit, which relates to a device for operating a low-pressure sodium vapor discharge lamp without a stabilizing ballast. This lamp features a discharge tube with first and second main electrodes opposing a third main electrode. An automatically operating change-over switch occasionally switches the lamp current to either the first or second electrodes. A reservoir of liquid sodium near the first electrode affects sodium vapor pressure in the discharge tube by the switching action.
Another significant patent is for a gaseous electric discharge tube featuring a coaxial, hollow cathode. In this design, the cathode is formed by a double-walled tube of tantalum or tungsten, with the inner tube being shorter. Under the influence of a discharge in the order of 100 A, the inner tube begins to glow. An auxiliary anode may also be present near the end of the cathode, enhancing the performance of the electric discharge tube.
