Abstract

A lamp (10) is described comprising a burner (14) fixed to a lamp base (12). The lamp base (12) includes a top wall oriented towards the burner (14). Within the top wall, an opening (28) is provided. The lamp base (12) further comprises an insulation chamber (42) where an electrical component, e. g. a transformer (54), is embedded within an insulation compound (43). In order to prevent possibly spilled insulation compound from leaking through the opening (28), a raised retention wall (46) is provided around the opening.
