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 light (1') with at least one reflector (7'), to which at least a first light source (4) is assigned, wherein the direction of emitted light beams of the at least onefirst light source (4) can be deflected by the reflector (7') in the direction of a specific observation position (P) at a distance from the vehicle light (1') in such a way that at least a first light function (LF1) can be perceived in said observation position (P) and can be emitted with at least one further light source (12) by the light beams by means of which the at least one second lightingfunction (LF2) can be perceived in the observation position (P). According to the invention, it is proposed that the at least one further light source (12) be present on a side of the reflector (7')facing away from the observation position (P), and at least one further, light-deflecting component (15') be arranged between the at least one further light source (12) and the reflector (7'), which component (15') is connected to the reflector (7') in such a way that light beams emitted by the at least one further light source (12) pass through the at least one further, light-deflecting component(15') and can exit the light-deflecting component (15') again in order to implement at least the one second light function (LF2) on a side of the reflector (7') facing the observation position (P). As a result, it is possible to make available a vehicle light with which a plurality of light functions can be easily superimposed and which is of compact design.

Description

technical field [0001] The invention relates to a vehicle lamp with the features of the preamble of claim 1 . 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, document WO 201...
