摘要:
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 LED modules (10) forms the auxiliary light distribution, wherein preferably at least one of the secondary LED light sources (12a) shines directly through the optical waveguide (14) in order to achieve a homogeneous light distribution contribution to the auxiliary light distribution, and wherein light is coupled by at least one of the secondary LED light sources (12) into the optical waveguide (14) via at least one light incoupling point (140) and exits directed substantially parallel via at least one light decoupling point (141) in order to produce a maximum contribution to the auxiliary light distribution.
