Abstract:
An illumination apparatus has a light source having a planar emission surface and a centroid, wherein the surface has a maximum distance L between opposite edges. A lens has an incident surface and an optical axis. In cross section along the optical axis, the incident surface, at a first incident point, is concave or flat to light emitted at a normal from the emissive surface. At a second incident point, the surface an instantaneous angle of curvature, relative to the emissive surface, with an absolute value of no more than 25 degrees to light emitted at an oblique angle greater than 75 degrees from the emissive surface normal. Considered in parallel to the optical axis, the second incident point is within a less than 0.2 L from the first plane. In an orthogonal direction to the optical axis, the second incident point lies within less than 2 L from the centroid.

Claim (Index 14):
An illumination apparatus comprising an array of light emitters, wherein each light emitter comprises:\n a) a solid-state light source having a planar emission surface that extends along a first plane and has a centroid, wherein the planar emission surface has a maximum distance dimension L measured as the length of a line through the centroid and extended along the first plane between furthest opposite edges of the planar emission surface; b) a lens that has an incident surface that is spaced apart from the planar emission surface and that has an optical axis normal to the emission surface, wherein, considered in a cross section along the optical axis, the incident surface curvature is:\n (i) concave or flat to light along a first optical path that extends from a first emissive point on the emissive surface to a first incident point on the incident surface, wherein the first optical path is at a normal with respect to the emissive surface of the light source; \n and \n (ii) concave to light along a second optical path that extends from a second emissive point to a second incident point on the incident surface, wherein the second optical path extends from the emissive surface at an oblique angle greater than 75 degrees from the emissive surface normal; wherein the instantaneous angle of the incident surface at the second incident point, relative to the first plane, has absolute value of no more than 15 degrees, \n wherein, in the direction parallel to the lens optical axis, the second incident point is within a first distance less than 0.1 L away from the first plane, and wherein, in a direction orthogonal to the lens optical axis, the second incident point lies within a second distance less than 2 L from the centroid and wherein, within the array, a distance between two adjacent light emitters is less than 3 L.
