The invention relates to a shield device for a headlamp, said device having a reflector with an opening that has a diameter of less than 38.2 mm and two luminous bodies. The shield device is designed in such a way that at least one boundary of the sector shielded by the shield device on the reflector in the vicinity of the opening, said sector lying on a straight line between the reflector opening and a circle around the reflector opening with a diameter of 38.2 mm, when viewed on a plane running parallel to the reflector opening.
摘要:
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.
摘要:
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.
摘要:
A lamp base has a plastic base part and a sprung metal ring, which is fixed to the plastic base part by webs integrally formed on the metal ring, the webs being designed such that there is a clamping fit between the webs and the plastic base part. The lamp base is preferably part of a vehicle headlamp.
摘要:
The invention relates to a lamp base having a color coding, the coding being formed by a plastic part, which is made from a colored plastic material. In addition, the invention relates to a lamp, preferably a vehicle lamp, having such a lamp base.
摘要:
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:
To ensure reliable electric contact, a discharge lamp has a tubular lamp vessel (1), a lamp base (4) and lamp electrodes (2, 3) which are applied to the wall of the lamp vessel (1) and in each case have an electrode section (20, 30) which is arranged outside the interior (11) of the lamp vessel (1) and serves as supply lead. The electric base contacts (5, 6) are connected in each case to an electrically conductive spring element (8, 9), each spring element (8, 9) bearing against the wall of the at least one tubular lamp vessel (1) and making an electric contact between in each case one electrode section (20, 30), arranged outside the lamp vessel (1), and a base contact (5, 6).
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:
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).
