Abstract
The invention relates to an LED light-source module (M, M1-M4) 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 (LED1, LED2), and wherein the light-emitting diodes (LED1, LED2) of each LED light source (LEQ) couple light into an associated primary optical element (P1-P4), wherein the incoupled light exits, at least partially, through a light exit surface (L1-L4) of the primary optical element (P1-P4), and wherein the light exit surfaces (L1-L4) of the primary optical elements (P1-P4) 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 (P1-P4) can enter the light-permeable material and can then exit this material through a light exit surface (LF1, LF2) of the light-permeable material.
