| 摘要 |
The invention relates to a flash lamp (10) comprising a glass gas-filled discharge tube (11) and, on each end, a power electrode (14, 15) that is sealed by means of a glass solder (13). The flash lamp has a glass, which comprises one or more of the following UV transmission values Tw: at 180 nm: Tw > 5 %, preferably > 9 %; at 200 nm: Tw > 30 %, preferably > 45 %; at 254 nm: Tw > 60 %, preferably > 80 %. The inside diameter of the discharge tube (11) can be larger than 1.2 times the value of the diameter of the plasma channel. The starting electrode (16) can be a part of the reflector (30-33) or can be electrically connected to the same. The flash capacitor (42) can be rated for a charging voltage of greater than 370 volts, preferably greater than 400 volts. |
