Latest Patents
One of Holcomb's latest patents is for a fill for high-temperature tungsten-halogen lamps. This innovation allows for satisfactory operation at temperatures exceeding 250°C. The design includes a high-temperature glass or quartz envelope that encloses a tungsten filament and molybdenum, with a fill comprising a mixture of noble gas, hydrogen, phosphorus, chlorine, and bromine. In a preferred embodiment, the chlorine and bromine are supplied by a single carbon atom hydrocarbon compound containing both halogens, such as CHClBr and CHBrCl.
Another significant patent is for an iodine lamp with molybdenum parts. This long-life tungsten halogen lamp features a fused silica envelope containing a coiled tungsten filament. The filament is connected across inleads sealed within the envelope, which include inner portions of molybdenum wire. The molybdenum wire has been treated to enhance its ductility and reduce surface impurities. The fill gas operates at a room temperature total pressure of at least 2,000 torr and comprises nitrogen, an inert gas, and an iodine-bearing component that provides from 3.1 × 10⁻⁷ to 9.6 × 10⁻⁷ gram atoms of iodine per cubic centimeter of envelope volume.
