Lanthanide oxide as an oxygen dispenser in a metal halide lamp |
摘要 |
A lamp includes a discharge vessel. Tungsten electrodes extend into the discharge vessel. An ionizable fill is sealed within the vessel. The fill includes a buffer gas and a halide component that includes a rare earth halide. A source of oxygen which includes a lanthanide oxide is present in the discharge vessel. The source of oxygen provides oxygen for a regenerative cycle which reduces blackening of the lamp walls by tungsten from the electrodes.
