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 17):
An optical apparatus comprising:\n a) a photonic component having a planar component surface that defines a component plane; b) a lens having a first lens surface for conveying light between the planar component surface that lies along the component plane and the lens, the first lens surface having a curvature that, considered in a cross section through an optical axis, is:\n (i) concave on a first optical path defined for light that is conveyed between a first point on the planar component surface and a first point on the first lens surface, wherein the first optical path is at a normal to the component plane, and \n (ii) convex on a second optical path defined for light conveyed between the first point on the planar component surface and a second point on the first lens surface, wherein the second optical path is at an oblique angle of more than 75 degrees relative to the optical axis, \n wherein the instantaneous angle for the slope of the first lens surface at the second point on the lens, relative to the component plane, has absolute value of less than 15 degrees, wherein, for a maximum distance dimension L measured between edges of the planar component surface, the second point on the first lens surface is within 0.1 L from the component plane in a direction parallel to the optical axis, wherein, in a direction orthogonal to the optical axis, the second incident point lies within 2 L from the optical axis; and, the lens further having a second lens surface, wherein at least a portion of the second lens surface that lies about the optical axis is convex.
