Abstract:
A motor vehicle headlight element is specified which has at least one light-emitting diode and at least one control apparatus. The control apparatus is suitable for processing a signal which is dependent on a measurement variable and for applying a current corresponding to the signal, to the light-emitting diode. The control apparatus and the light-emitting diode are arranged on a common mount.

Abstract:
A motor vehicle headlight module having at least two lighting units (1) is specified. Here, each lighting unit (1) comprises at least one light-emitting diode chip (2). Different lighting units (1) are provided here for different lighting functions. Furthermore, the motor vehicle headlight module has a common heat sink (6) for the lighting units, to which heat sink the lighting units are thermally connected, and a common current-stabilizing electronic system (8) for supplying voltage to the lighting units.
Abstract:
A luminaire for installing in the cover cap of an exterior rearview mirror for motor vehicles, has a luminaire housing and an electrical lamp arranged therein. The housing is entirely or partly of transparent design, such that in the installed state light exit surfaces of the housing are arranged both on the front side and on the rear side of the exterior rearview mirror. The lamp has a tubular, sealed lamp vessel, at least a portion of the lateral surface of the lamp vessel and an end face of the lamp vessel being of transparent design. Light directing elements for focusing the light emerging from the lateral surface and for deflecting the light emerging from the end face are provided such that the light emerging from the end face is directed toward a light exit surface arranged opposing the light emerging from the lateral surface.
Abstract:
The invention relates to a light-emitting diode module for a vehicle headlamp, which has a carrier for a number of light-emitting diodes and which carrier has a lateral surface of axially symmetrical design relative to a longitudinal axis, a number of light-emitting diodes being arranged on the lateral surface of the carrier, and the carrier being provided with at least one light directing means in order to direct in directions transverse to the longitudinal axis of the carrier the light emitted by the light-emitting diodes.

Abstract:
A solid-state light source (10) comprising a plurality of LED units (12) arrayed to emit light generally about an axis (14). Each of the LED units (12) can comprise a number of LEDs, for example, up to five. They may all emit in a single color or multiple colors can be combined for a specific effect. A light transmissive light guide (16) is associated with the LED units (12) and has a plurality of input widows (18). Each LED unit (12) faces a respective input window (18) and each window (18) transversely intercepts the axis (14) and receives light from the LED units (12). The input windows (18) lead to a common output window (20) that is axially aligned with the input windows (18). The light guide (16) has smooth sidewalls (22) that extend between the input windows (18) and the output window (20).
Abstract:
A retaining frame (2) having at least one optical element (3) secured thereto by injection molding, with the at least one optical element (3) being embodied for beam shaping at least by means of total internal reflection and/or diffraction.
Abstract:
A lighting apparatus may include an electrically conductive housing, in whose interior at least one light source and at least one electromagnetic radiation-emitting circuit component configured to operate the at least one light source are arranged; and an electrically conductive cover configured to cover the at least one circuit component; wherein the cover and the housing are electrically connected to one another.
