Latest Patents

One of Holger Claus's latest patents is a method for arc attachment stabilization. This method involves creating an arc between electrode tips during the start-up phase of a high-pressure arc discharge lamp. The process includes initially supplying power to the lamp for a specified period, transitioning the arc to attach itself between the tips of the electrodes, and then resupplying power after a second period. The timing for these power adjustments is based on elapsed time, measured operating lamp voltage, or lamp pressure. This technique ensures that the arc remains stabilized during the operation of the discharge lamp.

Another significant patent is for a non-oxidizing electrode arrangement for excimer lamps. This innovation involves coating the lamp's electrode with a protective layer that prevents oxidation. The protective layer is transparent and has low permeability for oxygen, utilizing materials such as silicon oxide, magnesium fluoride, or calcium fluoride. The excimer lamp is evacuated to a pressure lower than the surrounding environment during the electrode formation process, which helps prevent fracturing.
