Abstract
An LED module for a luminaire has a downwardly directed heat sink comprising cooling fins that extend rearward from the module'"'"'s front end and downward from its top wall, which has a top face that abuts the underside of a luminaire carrier plate. A circuit board carrying at least one LED is mounted on the front face, and a prism is mounted to the heat sink over the LED(s). The front (light-emitting) face of the catadioptric prism has several prominent side-by-side sections which emit beam patterns that diverge laterally and overlap in a central region. A prominent full-width upper section on the front face emits a primarily downwardly directed beam pattern to help fill in dark spots.

13. A catadioptric prism for shaping and directing light emitted by an even number of aligned, laterally spaced LEDs having a transparent body with a fore-and-aft medial vertical plane and comprising:
-
a rear light-receiving face; a front light-emitting face; a top face; a bottom face; and two side faces, said front face including; a prominent lower section on each side of said medial vertical plane, each lower section having a substantially vertical front and substantially vertical curved sides and that merge with said front; a prominent middle section above each lower section, the width of each middle section being greater than its height, each middle section having a substantially horizontal rounded face and rounded ends that merge with said rounded face; and a prominent upper section above both of said middle sections, said upper section having a downwardly and forwardly slanted surface, and said rear face including a convex cradle section on each side of said medial vertical plane, each cradle section having at least one pocket behind said middle section of said front face for cradling an LED, said pockets being symmetrically disposed on opposite sides of said medial vertical plane. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
