Patent ID: 8449159

Claim:
A light module ( 1 ), comprising: an LED array ( 2 ) centered around a horizontal longitudinal axis ( 9 ), the LED array ( 2 ) emitting light in an angular distribution centered around the longitudinal axis ( 9 ); a lens ( 4 ) disposed longitudinally adjacent to the LED array ( 2 ) for receiving light emitted by the LED array ( 2 ), the lens ( 4 ) having a thickness that is a maximum at the longitudinal axis ( 9 ) and decreases monotonically away from the longitudinal axis ( 9 ); and a reflecting surface ( 6 ) extending generally from the LED array ( 2 ) toward the lens ( 4 ); wherein proximate the LED array ( 2 ) the reflecting surface ( 6 ) has a lateral diameter generally equal to a lateral outer diameter of the lens ( 4 ); wherein the reflecting surface ( 6 ) has a base curvature ( 8 ) that is a paraboloid centered about the longitudinal axis ( 9 ) and having a focus disposed at a center of the LED array ( 2 ); wherein the reflecting surface ( 6 ) includes a plurality of facets superimposed on the base curvature ( 8 ); wherein the facets reflect light into a distribution proximate the longitudinal axis ( 9 ) and includes light that is directed farther away from the longitudinal axis ( 9 ) in both lateral directions and downward; wherein the lens ( 4 ) is supported by a generally transparent cover ( 3 ); wherein the cover ( 3 ) includes a peripheral portion ( 5 ) that laterally circumferentially surrounds the lens ( 4 ) and has a generally constant thickness throughout; and wherein the peripheral portion ( 5 ) and the lens ( 4 ) are both integral to the cover ( 3 ).
