Abstract
A solid-state lighting array for illuminating a predefined area includes a support member. A plurality of solid-state light-emitting devices is supported on the support member so that each device projects an essentially circular pattern of illumination onto the predefined area. At least a portion of the plurality of light-emitting devices is disposed so as to project a beam of light onto the predefined area at an oblique angle. The portion of obliquely angled devices have an astigmatic lens associated therewith so that the pattern of illumination incident upon the surface of the predefined area is essentially circular.

20. A solid-state lighting array for illuminating a predefined area, the array comprising:
-
a support member;
a plurality of solid-state light-emitting devices supported on the support member and spaced apart relative to each other;
wherein each of the plurality of light-emitting devices is angularly disposed relative to the support member so as to project a beam of light onto a portion of the predefined area, the plurality of devices having an adjustment device associated therewith for adjusting the beam of light so that the pattern of illumination incident upon the surface of the predefined area is essentially circular regardless of the angle of the plurality of lighting devices relative to the predetermined area.
