Definitions

  • An intermediate pressure gas are lamp comprising a tubular elongated envelope of sintered transparent high density polycrystalline alumina having a pair of electrodes sealed into opposite ends, an inert gas at a cold filing pressure of approximately 200 to 1250 millimeters sealed within said envelope and developing an operating pressure in the range of 1 to 10 atmospheres at volume loadings in the range of approximately 200 to 800 watts per cubic centimeter, the discharge space of said envelope having an eifective length several times its diameter and providing a cross section substantially filled by the discharge therethrough, the walls of said envelope about said discharge space operating at temperatures in the range of 1000 to 1600 C. and serving to stabilize said discharge throughout said range of volume loadings.
