Patent-Anspruch:Patent claim:Ein Lichtsignal, insbesondere für den Nachtdienst auf Eisenbahnen, bei welchem das Signal
als leuchtendes Band oder Streifen erscheint, erzeugt durch einen Refleclor C, welcher einen
Längsabschnitt eines Paraboloids darstellt, um die Achse dieses Paraboloids drehbar ist und
die Lichtstrahlen einer im Brennpunkte dieses Paraboloids angeordneten Quelle zurückwirft.A light signal, especially for night duty on railways, for which the signal
appears as a luminous band or stripe, produced by a reflector C, which has a
Represents longitudinal section of a paraboloid, about the axis of this paraboloid is rotatable and
reflects the light rays from a source arranged at the focal point of this paraboloid.

LASER OPTICAL SYSTEM FOR A VEHICLE HEADLIGHT IN WHICH A BEAM LENS FOCUSING A LASER BEAM IS IN DIRECT CONTACT WITH A LUMINOUS BODY EXCITED BY THE LASER BEAM
Day driving light, especially for motor vehicles, has light source with at least one LED and reflector for focusing light from source; LED(s) is built into optical system based on Cassegrain principle
Laser optical system for a vehicle headlight with a housing having a circuit board with laser light sources, reflectors, a heat sink and a white light generating light emitting section
Lighting device e.g. head light for vehicle e.g. motor car, has auxiliary light source provided in housing such that light emission is provided to interior of housing and emitted light beams are not directly emitted on light cover lens
Headlamp module for motor vehicle, has iris diaphragm arranged relative to luminous ring, where interior of luminous ring is closed by cover plates and is open when iris diaphragm is closed and opened, respectively
