Embodiment Construction
[0072] refer to figure 1 Explain the basic structure of the car light 1:
[0073] The vehicle light 1 is accommodated in a housing 2 which is closed by a transparent outer disc 3 in the direction of light radiation of the vehicle light 1 . The vehicle light 1 comprises at least three light sources 4 which are arranged on a printed circuit board 5 and which are actuated or controllable by means of a control unit 6 . The light sources 4 are arranged at various positions, as will be explained in more detail below. The light source 4 is in particular a light emitting diode. An optical element 7 is arranged in the light emission direction of the light source 4 . In the present embodiment, the optical element 7 is a reflector 7 , especially an associated reflector 7 . This reflector 7 has a reflector surface 8 which faces the light source 4, so that the light beam emitted by the light source 4 falls on the reflector surface 8 and can pass through the outer optical disk 3 outward...

The invention relates to a vehicle lamp (V) with at least one optical element (7') comprising a plurality of facets (9), wherein the optical element (7') can be changed via the facets (9). ) in the direction of the beam emitted in the direction of the beam. According to the invention it is proposed that an optical element (7') is associated with a plurality of light sources (4), wherein the light sources (4) can be manipulated and arranged relative to the position and / or orientation of the facet (9) such that the light sources (4) (4) The emitted light beam is reflected (LR) at the optical element (7') and the flicker effect can be perceived from a certain observation position (P), wherein the optical element (7') is constructed to be transparent and in the optical On the side of the element (7') facing away from the viewing position (P) there is at least one further light source (12) through which a light beam can be emitted which passes through the optical element (7') in the direction of the viewing position (P) (LT). As a result, a vehicle light can be provided with which a plurality of light functions can be generated in a simple manner and which has a particularly unique imaging pattern during operation.
Description
technical field [0001] The invention relates to a vehicle light with at least one optical element comprising a plurality of facets, wherein the direction of a light beam which can be emitted in the direction of the optical element can be changed by means of the facets. The invention also relates to a method for providing a light function by means of a vehicle light. Background technique [0002] Such a vehicle light is known from DE 10 2012 005 826 A1. Specifically, the optical element has a light coupling-in surface for coupling-in the light radiation of the light source and a decoupling structure, in which the direction of the coupled-in light beam is changed in such a way that an illumination characteristic is produced which is similar to the light radiation of the light source of the vehicle lamp The radiation characteristics are different. The decoupling structure includes a plurality of facets in which the light beams are decoupled at an illumination angle that is re...
