The invention relates to an LED light-source module (M, M-M) for an LED motor vehicle headlight (SW), in particular for an LED motor vehicle headlight (SW) for producing a dynamic light distribution, wherein the LED light-source module (M) comprises two or more LED light sources (LEQ), wherein one LED light source (LEQ) in each case comprises at least one light-emitting diode (LED, LED), and wherein the light-emitting diodes (LED, LED) of each LED light source (LEQ) couple light into an associated primary optical element (P-P), wherein the incoupled light exits, at least partially, through a light exit surface (L-L) of the primary optical element (P-P), and wherein the light exit surfaces (L-L) of the primary optical elements (P-P) of an LED light-source module (M) are connected to one another by means of a light-permeable material such that light coupled into the primary optical elements (P-P) can enter the light-permeable material and can then exit this material through a light exit surface (LF, LF) of the light-permeable material.

LED light-source module for a vehicle headlight

The invention relates to a vehicle headlamp () for producing a main light distribution and an auxiliary light distribution, wherein the vehicle headlamp () comprises two or more LED light modules (), wherein each of the LED light modules () comprises one or more primary LED light sources (), wherein a primary LED light source (') comprises at least one light-emitting diode, comprises two or more secondary LED light sources (), wherein a secondary LED light source () comprises at least one light-emitting diode (&#x2032;), and comprises a lens (), wherein the light emitted by the at least one primary LED light source () is radiated directly onto the lens () and projected by the lens into the exterior space, wherein the light emitted by the primary LED light sources () of a all LED modules () forms the main light distribution, and wherein the light emitted by the secondary LED light sources () of an LED modules () is radiated onto the lens () of the LED module () by means of an optical waveguide (), which lens () projects the light into the exterior space, and wherein the light emitted by the secondary LED light sources () of all LED modules () forms the auxiliary light distribution, wherein preferably at least one of the secondary LED light sources () shines directly through the optical waveguide () 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 () into the optical waveguide () via at least one light incoupling point () and exits directed substantially parallel via at least one light decoupling point () in order to produce a maximum contribution to the auxiliary light distribution.

LED light module

An LED light source module for an LED motor vehicle headlight is disclosed. The module comprises at least one LED light source composed of at least one light-emitting diode, which couples light into an associated primary lens wherein the in-coupled light at least partially exits a light exit area of the primary lens. The module also comprises a secondary lens, which images the light exiting the exit area&#x2014;when the headlight is installed in a vehicle&#x2014;as a light pattern onto a region located in front of the vehicle. A diaphragm assembly is provided between the light exit area and the secondary lens. The diaphragm assembly comprising at least one optically effective diaphragm edge, which is arranged and/or extends such that undesired distortions occurring in an upper and/or lower region of the light pattern are at least partially suppressed in the light pattern.
