Problems solved by technology

[0003] It has proven to be disadvantageous in this prior art to provide a reflector for the dipped beam, since on the one hand the reflector is relatively complex in construction and on the other hand it has relatively large dimensions

Embodiment Construction

[0036] In the figures, identical and functionally identical components are provided with the same reference symbols.

[0037] The illustrated embodiment of the headlight according to the invention includes a circuit board, not shown, on which a plurality of light sources in the form of light-emitting diodes (LEDs) are arranged. In this case, both a plurality of first light sources designed as light-emitting diodes for the high beam and a plurality of second light sources designed as light-emitting diodes for the low beam are arranged on the printed circuit board.

[0038] There is the possibility of using other light sources instead of light emitting diodes. For example, semiconductor lasers can also be provided as light sources.

[0039] Each light source can be controlled individually to switch between low beam and high beam. There is also the possibility to implement other functions of the adaptive headlight system (for example city lights, country lights or highway light...

Abstract

The present invention relates to a headlight, in particular a headlight of a motor vehicle. The headlight comprises at least one first light source for a main beam, which light source emits light during the operation of the headlight, and a first light directing means (1, 1a, 1b) which has at least one light input face (3, 3a, 3) for the light emitted by the at least one first light source, and atleast one light exit face (5, 5a, 5b), and also comprising at least a second light source for a dipped headlight (11) which emits light during the operation of the headlight, and a second light directing means (2) which has at least one light input face (4) for the light which is emitted by the at least one second light source, and at least one light exit face (6).

Description

technical field [0001] The invention relates to a headlight, in particular a headlight of a motor vehicle, according to the preamble of claim 1 . Background technique [0002] A headlight of the type mentioned is known from DE 10 2010 041 096 A1. The headlight described here includes a common circuit board for a plurality of light-emitting diodes (LEDs) for generating high and low beams. Light is emitted upwards from these LEDs. In this case, a light guide is provided for the high beam, into which light from a part of the light-emitting diodes is coupled in and deflected forward. Furthermore, a reflector arranged above the light guide means is provided, which reflects the light of the part of the light-emitting diodes which is used to form the dipped beam forwards. Not only the light reflected by the reflector, but also the light exiting the light guide passes through a common lens and exits the headlight forward. [0003] It has proven to be disadvantageous in this prio...
