Abstract
Not to decrease luminance of short-arc discharge lamp by preventing deposition of blackening contaminate on the light-emitting inner surface of the bulb of the lamp whose two electrodes are kept up and down while lighting. A groove 12 is formed on the bulb-end side edge-surface of the anode 4 placed at the upper side of the lamp. The cross section of the groove 12 is square-concaved, U-shaped, knife-shaped or V-shaped. The groove 12 steers the descending current from the upper end of the bulb 1 returning to the upper end of the bulb 1. The updraft along the side surface of the anode 4 goes toward the upper end of the bulb 1. The confluent gas of the descending current and the updraft strikes the inner surface near the upper end of the bulb 1. The gas current with blackening contaminate strikes the inner surface far off the light-emitting area of the bulb 1. Therefore, the blackening of the light-emitting area can be prevented.
