Abstract
The discharge lamp is held axially in an outer bulb. That end of the outer bulb which is remote from the cap is configured in such a way that it avoids the standard radially symmetrical convex shape. This substantially prevents reflection back onto the discharge vessel.

A high-pressure discharge lamp having a discharge vessel which is arranged axially in an outer bulb, has two seals and is equipped with an outer bulb, which is capped on one side, wherein that end of the outer bulb which is remote from the cap is configured in such a way that it reflects less radiation, in particular at least 50% less radiation, onto the discharge vessel, in particular onto the seal remote from the cap, compared to a convex, domed-shaped end of the outer bulb remote from the cap.
