Full-cutoff LED luminaire with front-pivot power door and heat sink with refractor mounting
First Claim
1. A full cutoff luminaire, comprising:
- a housing comprising an open side and a mounting end, wherein the mounting end is configured to mount the full cutoff luminaire to a mounting surface;
a power door disposed on the open side of the housing and pivotally coupled to the housing such that the power door swings away from the housing and mounting surface when the power door is released;
a heat sink coupled the power door,wherein the heat sink includes a top surface, a bottom surface opposite to the top surface, a heat sink body extending between the top surface and the bottom surface, and a plurality of heat sink fins extending radially outward from the heat sink body,wherein at least one heat sink fin of the plurality of heat sink fins has a hooked portion,wherein the hooked portion of the at least one heat sink fin is configured to engage a latching mechanism of a refractor or a reflector to couple the refractor or the reflector to the heat sink via the latching mechanism, andwherein the top surface of the heat sink is coupled to the power door; and
at least one light source that is coupled to the bottom surface of the heat sink.

Abstract
The present disclosure provides an LED luminaire capable of providing full cutoff illumination in a base configuration, without the addition of reflectors or refractors. The LED luminaire is also interchangeably couplable to one or more different reflectors and refractors. In certain example embodiments, the present disclosure provides a dusk to dawn luminaire operable as a full cutoff luminaire in a base configuration and which is also compatible with an American Nation Standards Institute (ANSI) dusk to dawn reflector/refractor assembly. In an example embodiment, the LED luminaire also includes a housing with a front pivoting door configured to swing away from a mounting structure when opened.
