Claim 17:
18. A method for providing illumination, the method comprising:
emitting first light from a plurality of first light-emitting areas of a first light-emitting diode (LED) array, the first light-emitting areas being separated by first boundaries;
collimating the first light to form first illumination;
illuminating a scene with the first illumination, the first light-emitting areas forming corresponding first illumination regions in the first illumination at the scene, the first boundaries forming first dark bands in the first illumination at the scene;
emitting second light from a plurality of second light-emitting areas of a second LED array, the second light-emitting areas being separated by second boundaries that correspond in a one-to-one correspondence to the first boundaries;
collimating the second light to form second illumination; and
illuminating the scene with the second illumination, the second light-emitting areas forming corresponding second illumination regions in the second illumination at the scene, each second illumination region at least partially overlapping with a corresponding first illumination region at the scene, the second boundaries forming second dark bands in the second illumination at the scene, the second dark bands being offset from the corresponding first dark bands at the scene.
