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.

Lamp comprising
- a burner fixed to a lamp base,
- where the lamp base comprises a housing element including a top wall element oriented towards said burner, where said top wall element comprises at least one opening,
- where said lamp base further comprises an insulation chamber, where an electrical component is embedded within an insulation compound,
- and where a raised retention wall is provided surrounding said opening, said raised retention wall extending from the top wall element into the housing element.
Method of manufacturing a lamp, the method comprising:
- providing a lamp base for a burner, said lamp base including a top wall oriented towards said burner, where said top wall comprises at least one opening,
- filling at least partially an insulation chamber within said lamp base with an insulation compound, thereby embedding an electrical component arranged within said insulation chamber, and
- providing a raised retention wall surrounding said opening, said raised retention wall extending from the top wall element into the housing element, thereby preventing said insulation compound spilled from said insulation chamber from leaking through said opening.
