Disclosed are a welding aid for a spiral-wound filament of a lamp and a lamp comprising such a welding aid. The spiral-wound filament has a spiral-wound filament body and at least one spiral-wound filament tail. The welding aid is arranged at a distance d from the spiral-wound filament body and is designed to connect the at least one spiral-wound filament tail to a current-conducting support, the distance d being defined in accordance with a power P at which the lamp is operated.

The invention relates to a halogen bulb comprising two filaments that are located (21, 22) in a lamp body (10), a first filament (21) being designed for operation at a higher electrical output than the second filament (22). To fulfil a daylight driving function, the second filament (22) is designed to produce an electrical output that is lower by a factor of 2.5 to 4 than the electrical output of the first filament (21) when operating with a standard operating voltage and is designed in such a way that it can be operated with an operating voltage that is lower than the standard operating voltage in order to produce a dimmed position light function.

Disclosed is a lamp, particularly for a vehicle headlight, comprising two spiral-wound filaments which are retained by three feeders within a bulb that is inserted into a base. The feeders are arranged on top of one another when the lamp is adequately oriented. A tail of the first spiral-wound filament is connected to a dimming cap, said tail being located at a distance from the base, while a tail of the second spiral-wound filament is connected to the central feeder, said tail being close to the base. The second filament tail that faces away and is located at a distance from the base is connected to the upper feeder. According to the invention, the lower feeder is connected to the dimming cap by means of an end, some sections of which are angled away from a longitudinal axis of the lamp.
摘要:
A lighting device includes at least one light-emitting diode (3) and a cooling aggregate (1) for cooling the at least one light-emitting diode (3), wherein the cooling aggregate (1) is provided with locking elements (17, 18, 19) adapted to form a bayonet catch with a fixing device (30) holding the lighting device. Preferably, at least one of the lighting devices is mounted as the light source in a vehicle headlight.

The invention relates to a lamp base for a high-pressure discharge lamp and to a high-pressure discharge lamp having a mounting plate for electronic modules and having a plug socket for connecting a voltage source to the lamp base, the plug socket being in the form of a surface-mounted module on the mounting plate.
摘要:
An electric lamp, in particular a motor vehicle auxiliary light lamp, and a method for producing such a lam. The base of the lamp comprises an annular metal part (5) or resilient design for holding the lamp vessel (1), and a plastic part (6) provided with at least one hollow contact pin (7, 8). A supply lead (3, 4) projecting from the lamp vessel (1) is threaded into the hollow contact pin (7, 8) and welded to the latter such that the metal part (5) is under mechanical stress. In this way, backlash-free plug-and-socket connections are produced between the lamp vessel (1) and the metal part (5) or between the metal part (5) and the plastic part (6).
摘要:
The invention concerns an electric lamp, particularly a high-pressure disrge lamp or halogen bulb with a base on one side for a motor-vehicle headlight. The base of the lamp of the invention has a base sleeve (110) comprised of an electrically insulating material and a mounting element (111) also comprised of an electrically insulating material, which bears lamp bulb (116) and which is joined with base sleeve (110). According to the invention, a metal part (121) is anchored in mounting element (111) and a metal ring (122) is anchored in base sleeve (110), whereby metal ring (122) is equipped with several shaped spring-type weld lugs (122), which are welded with metal part (121) anchored in mounting element (111).

To permit insertion of a lamp-socket combination into a fixture which includes a plate-like portion (P), for example a printed circuit board, a plastic socket (2) is provided which is formed with a recess (6), preferably a through-bore, into which two separating walls (8) extend, which are resiliently outwardly deflectable and have inwardly extending locating ridges (9) which can, after deflection radially outwardly upon insertion of the lamp (1), snap back against the base (4) of the lamp to engage over locating projections (5) formed on the base of the lamp. Terminal strips (7) are inserted in the base at the opposite sides of the separating walls (8), which defines chords of the cylindrical opening (6), the opening providing access for weld-connection of the electrical terminal leads (3) from the lamp to the terminal strips (7).
