Abstract

A lamp 10 is described comprising a burner 14 fixed to a lamp base 12. An operating circuit 50 is arranged within the lamp base 12 for supplying electrical power to the burner 14. The operating circuit 50 is electrically connected to at least one elongate contact path element 70 extending within the base. The contact path element 70 is supported within the base 12 and comprises a first portion 70a fixed within the base and a second portion 70b slidably received within the base 12. The contact path element 70 is fixed to the operating circuit 50 at a position arranged in longitudinal direction from the second portion 70b. This allows a manufacturing method, where the contact path element is fixed to the operating circuit 50 at a position arranged in longitudinal direction from the second portion, so that a longitudinal movement of the second portion is possible to compensate for manufacturing tolerances.
