Abstract
The invention relates to a vehicle headlamp (1) for producing a main light distribution and an auxiliary light distribution, wherein the vehicle headlamp (1) comprises two or more LED light modules (10), wherein each of the LED light modules (10) comprises one or more primary LED light sources (11), wherein a primary LED light source (11′) comprises at least one light-emitting diode, comprises two or more secondary LED light sources (12, 12a), wherein a secondary LED light source (12, 12a) comprises at least one light-emitting diode (12′), and comprises a lens (13), wherein the light emitted by the at least one primary LED light source (11) is radiated directly onto the lens (13) and projected by the lens into the exterior space, wherein the light emitted by the primary LED light sources (11) of a all LED modules (10) forms the main light distribution, and wherein the light emitted by the secondary LED light sources (12, 12a) of an LED modules (10) is radiated onto the lens (13) of the LED module (10) by means of an optical waveguide (14), which lens (13) projects the light into the exterior space, and wherein the light emitted by the secondary LED light sources (12, 12a) of all LE…
