The invention relates to an LED light source module (M1 to M4, M1′ to M4′) for an LED motor vehicle headlight (SWl, SWr), in particular for an LED motor vehicle headlight (SWl, SWr) for generating a dynamic light distribution, wherein the LED light source module (M1 to M4, M1′ to M4′) comprises at least one LED light source (LEQ), wherein the at least one LED light source (LEQ) is composed of at least one light-emitting diode (LED1, LED2), wherein the at least one light-emitting diode (LED1, LED2) of the at least one LED light source (LEQ) couples light into an associated primary lens element (P1 to P4), wherein the in-coupled light at least partially exits a light exit area (L1 to L4) of the primary lens element (P1 to P4) again, wherein the LED light source module (M1 to M4, M1′ to M4′) comprises a secondary lens (S1, S2, S3, S4), which images the light exiting the at least one light exit area (L1 to L4) of the at least one primary lens element (P1 to P4)—when the headlight (SW) is installed in a vehicle—as a light pattern onto a region located in front of the vehicle, and wherein according to the invention a diaphragm assembly (BAO) is provided between the at least one light exit area (L1 to L4) of the at least one primary lens element (P1 to P4) and the secondary lens (S1 to S4), the diaphragm assembly (BAO) comprising at least one optically effective diaphragm edge (BK1, BK2), 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.
