摘要:
To reliably and simply connect one end of a double-ended discharge vessel it (1) and a surrounding envelope (11) to a base (8), the base has a base sleeve (8a) which encloses a base holder portion (8b). The envelope (11) is melt-connected to the discharge vessel unit (1), for example just beyond pinch seals formed thereon, and is additionally formed with an extension (11a) which is, in turn, melt-connected to the holder portion (8b) of the base. Preferably, a metallic cuff is placed within the holder portion so that, by high-frequency inductive heating, a reception region (8d) of the holder portion can melt and tightly grip the extension (11a) of the envelope. To improve adhesion, the surface of the extension region (11a) may be ribbed, knurled or otherwise, slightly deformed.
摘要:
A discharge lamp (1) with a base (2), suitable for operation by means of a dielectrically impeded discharge, has a spacing between the base (2) and the outer wall of the discharge vessel (3). The overall efficiency of the generation of UV radiation is improved thereby.

Inserted into the cap of a high-pressure discharge lamp is a ceramic fleecehich prevents capping cement (17) from passing into the capillary (18) between the supply lead (9a) and pinch (5).
