Abstract:
1. An optical illumination system for mixing light and providing mixed light to a target location comprising: a multi-wavelength light source; and a first concave reflective optical element having a curved light receiving face having a first concave dish-like curvature, disposed to receive light from the light source, wherein the first concave reflective optical element is formed from an array of smaller side-by-side concave curved reflective dish-like elements disposed in a dish-like configuration following the first concave curvature and having their centers lying along the first concave dish-like curvature such that the first concave reflective optical element serves to focus or collimate light incident thereon received from the radiation source, wherein the two dimensional array of smaller concave reflective optical elements are arranged to direct sub-beams from the light incident thereon received from the radiation source toward the target location, wherein at least one of the smaller concave curved reflective dish-like elements are in a side-by-side relationship with at least three other of the smaller concave curved reflective dish-like elements.
