Abstract: In a vehicle lamp, in particular a side marking lamp for a motor vehicle, comprising at least one light source and at least one optical system (6a, 6b) arranged in the beam path of the light source, the substantially conical light beam issuing from the light source impinges directly on the optical system (6a, 6b) and shines therethrough, wherein the optical system (6a, 6b) is such that it produces therefrom a cruciform light distribution (3).

Abstract: A lamp, in particular a motor vehicle lamp, comprises a light distribution device (14, 14?) into which the light of at least one light source (6) is fed in such a way as to produce a light flux which is firstly propagated through the light distribution device substantially parallel to a light exit surface defined thereby. Components are deflected out of the light flux by means of coupling-out structures (16, 16?) for delivery through the light exit surface.

Abstract: A vehicle side-flashing lamp includes: a cup-shaped housing; a light exit opening opposite the housing bottom; and a light exit cover which covers the light exit opening. At least one light-emitting diode emits light outwardly at least partially at an angle which is large with respect to the main axis of the housing. A prismatic element, defined by first, second and third boundary surfaces, is arranged in front of the light-emitting diode in such a way that an emitted light beam passes through the first boundary surface into the prismatic element and is at least partially reflected at the second boundary surface, which is inclined with respect to the central axis of the light beam, in such a way that the reflected part issues from the prismatic element through the third boundary surface.

Abstract: In an electroluminescence light arrangement comprising a carrier substrate (1) of an electrically insulating material on which there is an electrically conductive layer from which there are formed at least two conductor track regions which are electrically insulated from each other and which form a first electrode (3) and a second electrode (5) and are covered over by a pigment layer (14) whose doped pigments light when an ac voltage is applied to the two electrodes, to increase the light brightness it is provided that at least in a portion of its surface the pigment layer (14) is covered over by a thin transparent electrically conductive cover layer (16) to which in operation no additional voltage is applied from the exterior.

Abstract: A plate such as a motor vehicle licence plate comprises a casing which includes a flat rear wall surrounded by a forwardly projecting edge defining a light transmission opening, through which a flat symbol carrier extending parallel to the rear wall of the casing is visible. The symbol carrier has regions of differing transparency to represent symbols thereon. An electrically activatable light film between the rear wall and the symbol carrier shines light through the symbol carrier from the rear. To provide retroreflective properties, arranged in front of the light film and parallel thereto is a film which extends at least over considerable parts of the area of the light transmission opening and which is at least partially transparent for the light from the rear and which is retroreflective for light impinging thereon from the exterior. A light cover which is transparent at least in region-wise manner closes the light transmission opening.

Abstract: A side flashing lamp for fitting into a cover cap of a motor vehicle external rear view mirror includes a lamp housing with a light exit opening and a translucent cover which closes the opening. The translucent cover is curved in such a way that it extends from the outward side, that is remote from the vehicle, in a continuous transition into the front side of the cover cap, which faces approximately in the direction of forward travel of the vehicle. The lamp has at least one light source in the lamp housing and at least one reflector for focusing the light of the light source in a main radiation direction which faces substantially in the direction of forward travel of the vehicle. The lamp includes at least one further light source with a reflector which focuses the light thereof transversely with respect to the main radiation direction.
