Discharge Lamp With a Cast Base

摘要

A discharge lamp with a cast base has two electrodes for feeding power into the discharge vessel, two current feeds for making contact with the electrodes from the outside and a lamp base with a recess for receiving one end of the discharge vessel. In this context, one end of the discharge vessel is introduced into the recess in the lamp base. Between the lamp base and the discharge vessel there is an intermediate space. The current feeds are located at least partially within the intermediate space. This intermediate space has been cast with a sealing compound so that the sealing compound fills at least part of the interspace and encloses the end of the discharge vessel in such a way that the current feeds of the discharge lamp are sealed off from the outside in so far as being located within the lamp base.
