Abstract: The reflector lamp has a reflector body (1) having a neck-shaped portion (4) with an end face (5). An electric lamp (10) having a lamp vessel (11) with elongate end portions (12,13) and in which an electric element (14) is present, is mounted inside the reflector body (1), its first end portion (12) being fixed in the neck-shaped portion (4) and its electric element (14) being aligned with respect to the optical axis (3) of the reflector body (1). The lamp (10) is fixed by means of a first (30) and a second clamping member (40), which are initially movable with respect to the lamp (10) and one to the other, and which are rigidly secured one to the other after alignment of the electric element (14). The first clamping member (30) is kept positioned against the end face (5).

Abstract: The illumination device has a capped electric lamp (1), a reflector (10) and retention means (20) for keeping the lamp (1) fixed to the reflector (10), an electric element (4) of the lamp (1) being aligned with respect to the reflector (10). The cap (5) of the lamp (1) has sphere discs and/or V-shaped grooves as reference means (7) around an axis (3) of its lamp vessel (2), with respect to which the electric element (4) is aligned. The reflector (10) has about an opening (12) for inserting the lamp (1) V-shaped grooves and/or spherical discs as the alignment means (13), cooperating with the reference means of the lamp cap (5). The reference means (7) and the alignment means (13) allow for an easy, fast and reliable mounting of the lamp (1) in the reflector (10), the electric element (4) occupying a predetermined position therein.

Abstract: The high-pressure discharge lamp has a discharge vessel (1) with seals (2) on each of which a metal clamping plate (20) is present. The discharge vessel is accommodated in an outer bulb (10) which has cylindrical portions (12). The clamping plates (20) have transversely flanged rims (24, 25) from which elastic tongues (23) extend towards the outer bulb in tangential direction and press against a cylindrical portion (12) of the outer bulb with clamping force. The clamping plates (20) render it possible to suspend the discharge vessel (1) in the outer bulb (10), keeping the discharge vessel centered and forming a buffer in the case of shocks.

Abstract: The capped electric lamp has a lamp cap with a central cavity which provides access to a first contact member, a first portion of the lamp vessel being fixed in this cavity. A second conductor is connected to a second contact member separate opening. The first contact member is centrally positioned, the second contact member is positioned on a concentric cylinder. The lamp cap has projections for fixation of a connector. A connector for the lamp has a central first contact and a second contact on a cylinder concentric therewith, as well as a fixing device for cooperating with the lamp cap for the purpose of fixation. The connector may be coupled to the lamp cap in several relative rotational positions.

Abstract: The HID lamp, suitable for use as a vehicle headlamp, includes a lamp cap having a first, central recess, a second, annular recess surrounding the central recess, and a third recess separated from the first and second recesses. The recesses accommodate a first end of the discharge vessel and a first current supply conductor, a fixation member, and second current supply conductor, respectively. The fixation member is frictionally fixed in the annular recess by resilient tongues and is welded to a clamping member holding a sealed end of the discharge vessel. The lamp construction allows for adjustably mounting the discharge vessel to the lamp cap and avoids harmful and disadvantageous electrical high-voltage and high-frequency effects through electrical isolation of the clamping and fixation members.

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: A motor vehicle headlamp has a light source (4) with an axis (5) and is mounted in an accurately defined position relative to reference tabs (15) of a positioning member (14). To this end, the lamp has at its base a holder body (10) which includes a retaining member (12) which is adjustably fastened to the lamp vessel (1), a coupling member (16) which is telescopically aligned with and fastened to the retaining member (12), and a positioning member (14) fastened to the coupling member. The coupling member (16), before being fixed in position, can be shifted in two mutually perpendicular directions over a surface (19) of the positioning member (14). A reflector body for the headlamp has an opening having a boundary wherein a pressure member is provided and which bears against a flanged tongue (41) of the positioning member (14) when the headlamp is placed in the reflector body, thereby maintaining the headlamp in position.

Abstract: The low-pressure discharge lamp has a tubular lamp vessel provided at its both ends with a lamp cap having a pair of contact pins. Each lamp cap is fixed in an adapter having one central contact pin electrically connected to at least one of the pair of contact pins of the lamp cap. A lamp of ordinary construction when provided with the adaptor is thus suitable for use in a space containing explosive gas.

Abstract: The assembly comprises a light housing (1) provided with a resilient holding device (7, 7', 8) for an electric lamp (31). The holding device has a first holding member (7, 7') which is bipartite (7, 7'), is rigidly connected to the light housing (1) and has contact regions (9) formed on the limbs of a V. The electric lamp (31) has two lamp caps (40, 41), which have a cylindrically curved surface (42), which is pressed against the contact regions (9) by a second resilient holding member (8). The light source (36) of the lamp (31) is held in a predetermined position in the light housing (1).

Abstract: The tubular electric incandescent lamp has at its ends metal hoods, to which current supply conductors are secured. The metal hoods are accommodated in an insulator housing provided with an opening, through which a contact member extends to the exterior. The contact member is a metal strap with resilient tongues, which engage a metal hood behind a collar. The insulator housing has a tapering slot with a widened part, in which free end portions of the metal strap are enclosed. The unit of contact member and housing thus obtained is undetachably connected to the lamp in that it is axially slipped around the metal hood.

Abstract: The capped electric lamp has a metal clamping member which surrounds a longitudinal part of the lamp vessel with a clamping fit and is secured to a metal bushing. The lamp cap has a metal sleeve secured therein which receives the metal bushing with telescoping fit to allow alignment of the lamp vessel with the lamp cap. After alignment, the metal bushing is fixed to the sleeve, for example, by welding. A dimming hood is secured in the aligned state to the bushing. A current-supply conductor extends through a tubular part inside of the lamp cap to a contact member of the lamp cap.
