摘要 |
A fluorescent lamp (10) includes a tubular member or envelope (12) having an arc generating and sustaining medium (15) therein. As known, the tubular envelope (12) is constructed of a suitable glass, for example lime glass. An electrode (14) is provided in each end of the tubular member (12) and a phosphor coating (16) is applied to the interior surface (18) of the tubular member (12). A mercury dispenser (20) is situated within the tubular member (12). The mercury dispenser (20) includes a body (21) composed of a material selected from the group consisting of glass and ceramic materials. The body (21) is provided with a bore (22). A first material (24) capable of wetting mercury coats the bore. In a preferred embodiment the first material (24) is silver having a thickness between 0.1 µ and 8 p. A quantity of mercury (26) is deposited in the bore (22) in contact with the first material (24).
