A multi-LED array (10) comprising plurality of spaced apart LED light emitters (12), wherein at least two of the plurality of LED light emitters (12) have a different rotational orientation with respect to one another. The LED light emitters (12) comprise discrete LED dies disposed on a substrate (14), or LED elements formed in a single LED die, having different rotational orientations with respect to one another. The array produces relatively rotated overlapping beams with an overall circular or elliptical illumination pattern. |
