Embodiment Construction

[0074] refer to figure 1 Explain the basic structure of headlight 1:

[0075] 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. A reflector 7 , in particular an associated reflector 7 , is arranged in the light emission direction of the light source 4 . 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 outwards to the viewing position P as a reflected light beam LR. . The light bea...

Abstract

The invention relates to a vehicle lamp (1') with at least one reflector (7') associated with at least one first light source (4), wherein the emitted light beam of the at least one first light source (4) The direction of the reflector (7') can be deflected in a certain direction away from the viewing position (P) of the vehicle light (1') in such a way that at least one first light function (LF1) can be perceived here, And with at least one further light source (12), from which a light beam can be emitted, through which at least one second light function (LF2) can be perceived in the viewing position (P). It is proposed according to the invention that there is at least one further light source (12) on the side of the reflector (7') facing away from the viewing position (P), and that at least one further light source (12) is connected to the reflector (7') At least one further light deflecting member (15') is arranged in between, which is connected to the reflector (7') in such a way that the light beam emitted by the at least one further light source (12) can pass through the at least one further light source (12). The light-deflecting component (15') can also be separated from the light-deflecting component (15' on the side of the reflector (7') facing the viewing position (P) for at least one second light function (LF2) ). As a result, a vehicle light can be provided with which a plurality of light functions can be superimposed in a simple manner and which is of compact design.

Description

technical field [0001] The invention relates to a vehicle lamp. It also relates to a method for providing a light function by means of a vehicle light. Background technique [0002] Document US 6,857,769 B2 describes a vehicle lamp of this type. In the case of this vehicle light, the two light sources are separated from each other by a semi-transparent, specularly reflective strip. The first light source is associated with the light function of the dipped beam, and the second light source is associated with the light function of the parking light. The light beams of the first light source pass through the semi-transparent, specularly reflected strip, while the light beams of the second light source are specularly reflected on the strip and are thus deflected in the direction of travel. In this way, it should be possible to realize a plurality of light functions in a relatively small housing. [0003] Likewise, WO 2010 / 120251 A1 discloses a vehicle light in which two refl...
