Abstract

A lamp (10) for an automotive headlamp and a method for manufacturing such kind of a lamp (10) is provided, wherein the lamp (10) comprises a burner (12) for emitting light, a metal holder (20) connected to the burner (12) for supporting the burner (12), a first socket part (32) made from a heat-resistant plastic material, which is connected to the burner (12), and a second socket part (34), through which a part of the burner (12), which is connected to a first electrical pole (14), is led for connecting the burner (12) to a voltage source, wherein the second socket part (34) is arranged adjacent to the first socket part (32) such, that at least one insulating gap (42) for providing voltage resistance in mainly radial and/or axial direction is provided. Due to the first socket part (32) it is possible to receive the hot burner (12) by the socket without impairing the heat resistance, wherein the second socket part (34) may be made from a cheaper material. This leads to a reduction of production costs without impairing the heat resistance or the voltage resistance provided by the insulating gap (42) between the first socket part (32) and the second socket part (34).
