a first light-emitting diode, LED, array being arranged on a substrate and having a first perimeter, said first LED array comprising a plurality of first LEDs configured to emit first light;

a second LED array being arranged on the substrate and having a second perimeter smaller than said first perimeter, said second LED array comprising a plurality of second LEDs configured to emit second light; and

a controller configured to individually control the first LED array and the second LED array,

wherein the second LED array is arranged off-center within said first LED array and,

wherein said first perimeter encloses a first surface area and said second perimeter encloses a second surface area, and wherein at least 70% of the second surface area is arranged in one half of the first surface area wherein an optical structure is arranged along the second perimeter to redirect said first light and said second light toward the substrate and/or toward a housing in which the substrate is arranged.
