Abstract: The lamp/reflector unit has a reflector body (1) provided with a neck-shaped portion (4) with relief (6). An electric lamp (7) provided with contact pins (8) is mounted in the reflector body (1). The neck-shaped portion (4) has a separate first part (9), which extends from the free end (5) of the neck-shaped portion (4) to beyond the relief (6), and a second part (10), which is integral with the reflector body (1) and which lies at least in part within the first part (9). The unit has a simple and rigid construction.

Abstract: The assembly of a headlight and a connector has in the headlight an electric discharge lamp with a lamp cap and contacts at this lamp cap, which cap is attached by a fixing member to a reflector. The headlight has beside the lamp cap a contact member. The connector has main contacts for the lamp and additional contacts adapted to cooperate with the contact member. It is not until the contact member interconnects the additional contacts that a high voltage is applied across the main contacts of the connector.

Abstract: The capped vehicle headlight lamp has a solid lamp cap with integral current supply conductors. The first ends of the current-supply conductors form lamp contacts. The current-supply conductors extend parallel to the lamp cap center line and have portions at right angles to the center line and at right angles to each other. The lamp vessel has current lead-through conductors, which are arranged diametrically opposite to each other and extend at least substantially along the center line of the lamp cap. The lamp may comprise a dipping cap, which is connected without a seam to the lamp cap and in whose wall a current supply conductor is included. The invention renders it possible to firmly secure the lamp vessel and the lamp cap to each other in an aligned position, while the construction of the lamp is nevertheless simple and reliable. Furthermore, a conductor not conveying current can be included in the dipping cap.

Abstract: An electrical lamp having a cap of synthetic material. A lamp vessel with a pinch seal is fixedly secured in a metal plate which is welded to a metal sleeve. The sleeve is rigidly secured in a two-part cup-shaped lamp cap which has a mounting flange and a groove for a sealing ring. The lamp cap is formed of first and second bodies of synthetic material which are rigidly connected to each other, the metal sleeve being locked to the first body, and the groove walls being formed by respective parts of each of the bodies.

Abstract: A lamp, such as a replaceable halogen unit for an automotive head lamp, has a transparent vessel pinch seal gripped in a clamping plate which has a circular cylindrical flange. The lamp cap is cup-shaped, and made of synthetic material having electrical contacts passing through the bottom of the cap. The lap vessel is connected to the cap by a metal cup-shaped sleeve, whose bottom is mechanically secured to the lamp cap, preferably by a rivet which also secures a contact in place.

Abstract: In a lamp according to the invention the use of cement for connecting the lamp cap (4) has been avoided by using a split metal ring (8). The neck-shaped lamp envelope portion (2) has recesses (13) in which projecting parts (12) of the ring (8) engage. The ring (8) has lugs (14) which at least initially press against the lower edge (3) of the neck-shaped lamp envelope portion (2). The ring (8) is secured to the lamp cap (4). During assembly of the lamp cap (4) the lugs (14) are deformed. A resilient force thereby induced in said lugs pulls the ring (8) in a direction opposite to the direction in which the lamp cap (4) was moved. As soon as the ring (9) is secured to the lamp cap (4), the resilience in the lugs (14) is of no further significance.

Abstract: A capless electric incandescent lamp comprises a lamp envelope having a flat pinch. A first wide side face of this flat pinch has current supply wires bent backwards along the extent thereof. A second wide side face of this pinch has means to suitably cooperate with a fixing member in a lampholder.
