Patent ID: 8657475

Claim:
A light source comprising: a monolithic emissive semiconductor device; and an array of lenslets, the lenslets being optically and mechanically coupled to the monolithic emissive semiconductor device; wherein the monolithic emissive semiconductor device comprises an array of localized light emission regions, each region corresponding to a given lenslet; wherein the lenslets have an apparent center of curvature (C a ), an apparent focal point (f a ), a radius of curvature (R) and a lenslet base diameter (D), the base diameter being the width of the lenslet at the intersection with the monolithic emissive semiconductor device; wherein the distance along the lenslet optic axis between the C a and the f a are normalized, such that C a is located at distance 0 and f a is located at point 1; wherein each localized light emission region is located at a point that is greater than 0, and less than ( - 3.6 · ( R D ) + 2.75 ) ; and wherein each light emission region has a diameter, the emission region diameter measuring one-third or less of a corresponding lenslet base diameter.
