In an embodiment a reflector optical system includes a reflector body having a rotational symmetry about a longitudinal axis and including a first reflector optic portion having a substantially concave shape and a second reflector optic portion extending along the longitudinal axis, the first reflector optic portion facing the second reflector optic portion, wherein the first reflector optic portion includes a plurality of first reflective surfaces and the second reflector optic portion includes a plurality of second reflective surfaces in spaced light-receiving relation to the plurality of first reflective surfaces.

Reflector optics for a vehicle retrofit headlamp

An automotive solid-state headlamp includes a lamp body extending in a longitudinal direction, the lamp body having a rear base portion and a front portion and including a support member and a light-transmissive housing, a plurality of solid-state light sources arranged on the support member at the rear base portion of the lamp body, a drive circuitry electrically coupled to the light sources and arranged at the rear base portion of the lamp body and configured to operate the plurality of light sources when energized and reflector optics arranged at the front portion, wherein the solid-state light sources are configured to emit light towards the reflector optics, the reflector optics including a first reflector optic portion and a second reflector optic portion and wherein each of a plurality of first reflective surfaces disposed on the first reflector optic portion extend in an annular region around the longitudinal direction from the plurality of solid-state light sources towards the first reflector optic portion.

Vehicle retrofit headlamp having reflector optic portions facing each other

In an embodiment an automotive solid-state headlamp includes a lamp body extending in a longitudinal direction, the lamp body having a rear base portion and a front portion and including a support member disposed in a light-transmissive housing, a plurality of solid-state light sources arranged on the support member at the rear base portion of the lamp body, and a drive circuitry electrically coupled to the light sources and arranged at the rear base portion of the lamp body and configured to operate the plurality of light sources when energized, wherein the plurality of light sources, when energized, are configured to cause the solid-state lamp to emit, through the light-transmissive housing (a) a luminous flux of at least 1500 lumens +/&#x2212;10% when energized with a 13.2 Volt test voltage, or of at least 1750 lumens +/&#x2212;10% when energized with a 28 Volt test voltage, or (b) a luminous flux of at least 1350 lumens +/&#x2212;10% when energized with a 13.2 Volt test voltage, or of at least 1600 lumens +/&#x2212;10% when energized with a 28 Volt test voltage.

Vehicle lamp

An incandescent halogen lamp for vehicle headlights may include a lamp base which defines a reference plane for orienting the incandescent halogen lamp in the vehicle headlight and includes a holder part having a substantially rotationally symmetrical external contour for holding a translucent lamp vessel, with the holder part having a first holder-part section connected to a component of the lamp base and a second holder-part section from which the translucent lamp vessel projects, wherein the second holder-part section has a smaller external diameter than the first holder-part section and wherein the height of the lamp base above the reference plane is in the 11.5-to-16.6-mm range.

Halogen incandescent lamp for a vehicle headlight

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.

Welding aid for a spiral-wound filament

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.

Two-filament lamp

The invention relates to a dipping cap comprising a filament for a dual-filament lamp. The dimension between an outlet of an outgoing section of the filament, on the side of the base, and the point on the outgoing section of the filament, arranged opposite the outgoing section of the filament on the side of the base and welded to the dipping cap, measures more than approximately 5.2 mm and less than 9.7 mm, and the dimension between the outlet of the outgoing section of the filament, on the side of the base, and the front surface of the dipping cap, which is adjacent to the outgoing section of the filament, welded to the dipping cap, measures more than approximately 5.9 mm and less than 11.9 mm.

Anti-dazzle device with a filament

Disclosed is a lamp, particularly a halogen incandescent lamp, comprising a bulb that is provided with a pinch seal which is inserted into a base by means of an attachment ring. The attachment ring has a receiving section within which the pinch seal is clampingly fastened by means of attachment ring brackets that are supported on support surfaces. According to the invention, the support surfaces are placed at an angle from the longitudinal axis of the lamp.

Lamp featuring an improved pinch geometry

The invention relates to a halogen bulb comprising two filaments that are located () in a lamp body (), a first filament () being designed for operation at a higher electrical output than the second filament (). To fulfil a daylight driving function, the second filament () 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 () 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.
