Prismatic LED module for luminaire

摘要

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.
