Latest Patents

Orr's latest patents include the "RF driven sulfur lamp having driving electrodes which face each other" and the "RF driven sulfur lamp having driving electrodes arranged to cool the lamp." Both patents describe a high intensity discharge lamp that radiates a spectrum almost entirely in the visible range. These lamps utilize a signal source to generate an excitation signal that is coupled to the exterior surface of the lamp's envelope, which contains a sulfur-containing substance. Various embodiments of the lamp feature electrodes shaped to complement the envelope's exterior, with designs that include spherical and cylindrical shapes. To minimize filamentary discharges, the envelope may include an elongated stem that allows for rotation. Additionally, the envelope can have a Dewar configuration with electrodes positioned strategically to enhance performance. The use of an inert gas backfill at specific pressures further optimizes the lamp's output and spectrum.
