  • High pressure metal halide lamp with electron collector
    Patent number: 3995928
    Abstract: A high pressure metal halide lamp comprises an outer envelope and an inner fused silica arc tube whose fill includes sodium iodide. Notwithstanding the use of a divided mount side-rod-less construction, the arc tube is subject to loss of sodium by electrolysis through the walls. The sodium loss is reduced by means of a collector wire within the outer envelope having a control potential thereon which shadows the current carrying lead wire in order to collect electrons that otherwise drift to the arc tube and promote electrolysis.
