Low pressure gas discharge lamp.

摘要

A low pressure gas discharge lamp is made up of a light-emitting tubular bulb (2) whose elongated discharge space (3) contains a discharge gas including at least a xenon gas, an internal electrode (4) sealed within the bulb and located at one end of the bulb, a band-like external electrode (7) formed on the outer surface of the bulb and extending up to the other end of the bulb in the axial direction of the bulb, and a fluorescent material (6) coated on the inner surface of the bulb. The xenon gas contained in the discharge space has a partial pressure within the range of 5 to 40 Torr.
