the second light, the second optical element being configured to influence the second light in such that it is emitted diffusely from the LED lighting module in a solid angle around the direction R, wherein the second optical element forms a U-shaped cross section channel extending adjacent to and around a periphery of a central region, the second optical element arranged inlaid in the first optical element. ### Claim 2 (depends on 1) The LED lighting module as claimed in claim 1, wherein the first LEDs and the at least one second LED are arranged in such a way that as observed counter to the direction R, the first LEDs are arranged in the central region and the at least one second LED is arranged in an outer region. ### Claim 3 (depends on 2) The LED lighting module as claimed in claim 2, wherein a plurality of second LEDs are at least two of the second LEDs being arranged on two opposite sides of the central region. ### Claim 4 (depends on 1) The LED lighting module as claimed in claim 1, wherein the at least one second LED comprises at least four second LEDs spaced around the central region. ### Claim 5 (depends on 1) The LED lighting module as claimed in claim 1, wherein the first LEDs and/or the at least one second LED are arranged in a matrix on the printed circuit board. ### Claim 6 (depends on 1) The LED lighting module as claimed in claim 1, wherein the first optical element comprises a plurality of lens elements and configured so that precisely one of the plurality of lens elements is assigned to each of the plurality of first LEDs. ### Claim 7 (depends on 1) The LED lighting module as claimed in claim 1, wherein the first optical element forms a first housing part of the LED lighting module. ### Claim 8 (depends on 1) The LED lighting module as claimed in claim 1, wherein the first optical element is configured to influence the first light so that it is emitted without glare from the LED lighting module. ### Claim 9 (depends on 1)
