1. A light emitting device comprising:
an array of multiple LEDs arranged so as to emit array output light, the LEDs of the array being separated from one another by trenches filled with non-transparent material or by non-transparent walls;
one or more optical elements arranged so as to direct at least a portion of the array output light to form an image of the array; and
one or more light diffusing structures positioned in a light path between two or more light emitting elements of the array and one or more of the optical elements, the one or more light diffusing structures being arranged so as to reduce or eliminate, in the image of the array, appearance of the trenches or walls.
