Abstract: Automotive headlight lamps of different kinds have identical burners and upper base parts, but lower base parts of different structures. The upper base part has reference elements, for example, a securing ring, for positioning the lamp at a headlight. The lower base parts vary from one kind of lamp to another, having, for example, different connection devices for electrical contacts. In the lamp manufacturing process, a burner is inserted into an upper base part and, preferably, after having been oriented with respect to a reference element, is fixed in position. Lower base parts including the electrical connection device and having a desired shape are connected with the upper base parts. A two-piece embodiment of the lower base part is also possible, enabling electrical contact elements to be readily accommodated.

Abstract: A lamp includes a burner configured to generate light and a base having a first part connectable to a second part. The first part is configured to hold the burner in a fixed position, and the second part is configured to allow electrical connection to the burner. The first and second base parts are made of different plastic materials, where the material of the first base part has a higher temperature stability and/or resistance to UV radiation then the material of the second base part. The first and second base parts are connected together by welding and/or bonding using an adhesive.

Abstract: A lamp (24), a series of lamps as well as a method of manufacturing lamps, in particular lamps for automotive headlights, are described. Said lamps (24) comprise a burner (26) for generating light, which burner is held in position in an upper base part (12). Said upper part (12) of the base also comprises reference elements, for example a securing ring (16), for positioning the lamp at a headlight. In addition, a lower base part (14) comprising a connection device for electrical contacts is provided. The lower base (14) part and the upper base part (12) are at least partly made of plastics and are connected together by means of welding or bonding using an adhesive. In a series of lamps, all lamps of said series comprise identical burners (26) and identical upper base parts (12), while different types of lower base parts (14) are available.
