1. A light emitting device comprising:
a carrier comprising:
a first plurality of LEDs arranged in a matrix arrangement, the matrix arrangement having a plurality of LED columns and a plurality of LED rows, wherein LED columns of the plurality of LED columns are spaced apart from each other with a first spacing and LED rows of the plurality of LED rows are spaced apart from each other with a second spacing, and
a second plurality of LEDs arranged in a linear arrangement, the linear arrangement having a length larger than a width, wherein LEDs of the second plurality of LEDs are spaced apart from each other with a third spacing, the third spacing being smaller than the first and the second spacings and wherein the second plurality of LEDs are arranged in between LEDs of the first plurality of LEDs and within the first and the second spacings,
wherein a ratio between a number of LEDs of the second plurality of LEDs arranged along the length and a number of LEDs of the second plurality of LEDs arranged along the width is at least 10, or the length of the second plurality of LEDs is at least twice a length of an LED column of the plurality of LED columns and/or is twice a length of an LED row of the plurality of LED rows of the first plurality of LEDs.
