摘要： A mercury supplying method capable of always supplying a constant amount of mercury into a chamber part easily by executing measurement and ejection of the mercury at the same time. A small diameter pipe as a mercury supply path, is inserted through a glass tube elongating from a chamber part of an arc tube from above so as to have the tip part thereof substantially reaching into the chamber part, and connecting the upstream side of the sealed mercury supply path (mercury barrel) with a gas pressure adjuster. The gas pressure adjuster keeps the inside of the mercury supply path (mercury barrel) at a predetermined pressure so as to maintain the inside of the small diameter pipe in the state filled with mercury as well as applying a predetermined pressure to the mercury in the small diameter pipe for a predetermined time and thus ejecting a predetermined amount of mercury from the small diameter pipe tip part so as to be dropped and supplied to the chamber part. Measurement and ejection of the mercury can be executed at the same time with the small diameter pipe inserted through the glass tube of the arc tube from above. A predetermined amount of mercury can always be supplied into the chamber part in a short time.

摘要： A mercury-free arc tube for a discharge-lamp device having a sealed glass chamber with at least metallic halide for main light emission and rare gas. Both end openings of a glass tube are pinch-sealed and electrode bars are provided so as to oppose to each other. Each electrode bar has such a concentric stepped shape that a tip side region is thicker than a base side region, the volume V of an electrode embedded region is from 0.25 to 0.42 mm3 and the total volume of the electrode bar is from 0.4 to 0.6 mm3.

摘要： The arc tube is provided with a mercury-free arc tube main body that has a discharge light-emitting portion (closed glass sphere), and a cylindrical shroud glass tube that is airtightly integrated with the arc tube main body. In the mercury-free arc tube in which an inert gas is sealed in the shroud glass tube that surrounds the closed glass sphere, in the shroud glass tube, the adjustment is made so as to satisfy the light flux and the life span with respect to the pressure X (atmospheric pressure) of a rare gas sealed in the closed glass sphere, and an amount M (mg/ml) of sealed metal halide.
