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.

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.

Abstract: A lamp (10) is described comprising a burner (14) fixed to a lamp base (12). The lamp base (12) comprises a metal housing part (40). The metal housing part (40) comprises a contact sheet element (82) made out of a different metal material. Electrical contacts are provided within the base (12), including an electrical ground contact (70). A contact spring (76) is provided for contacting the electrical ground contact (70) to the metal housing part (40). The contact spring (76) is arranged to press against the contact sheet element (82) to provide electrical ground connection to the metal housing part (40).

Abstract: A description is given of a gas-discharge lamp base (11) with a housing comprising an upper part (10) and a cover (40), a support (16) accommodated in the housing for receiving the components, with a transformer, with inductances connected in series with the lamp (1) and a capacitance connected in parallel with the lamp (1), the transformer comprising a bar transformer (23). This construction permits particularly efficient production, because the support can be constructed as a simple leadframe which permits automatic component fitting.

Abstract: A gas discharge lamp base (1) with a starting device has a carrier part (16) for electronic components (23 through 30) of the starting device. The carrier part (16) has a top side and a bottom side. Only high voltage-carrying components (23 through 26) of the starting device are arranged on the one side of the carrier part (16), and only low voltage-carrying components (27 through 30) of the starting device are arranged on the other side (low voltage side) of the carrier part (16).
