摘要： A system for generating infrared light includes a sealed housing and a noble gas filling the housing. A window disposed in a wall of the housing is transparent to infrared radiation. Two electrodes, disposed in the housing, are aligned along a common longitudinal axis adapted to be approximately perpendicular to a local force of gravity. A gap is defined between the electrodes along the longitudinal axis. Obstruction(s), disposed in the housing adjacent to the gap between the electrodes, extend along the length of the gap. The obstruction(s) define a convection space between the electrodes. The convection space has a dimension, measured perpendicular to the longitudinal axis, in the range of 2 to 10 times the length of the gap. An electric current source is coupled to the electrodes.
