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;
a power door coupled to the open side of the housing via a hinge at a first end of the power door and a releasable coupling feature elsewhere on the power door;
a heat sink coupled to the first end of the power door opposite the housing,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 each heat sink fin extends from the top surface towards the bottom surface of the heat sink,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 attached to the power door; and
at least one light source mounted to the bottom surface of the heat sink opposite the power door via a circuit board disposed between the bottom surface of the heat sink and the at least one light source,wherein the power door swings away from the housing and mounting end, pivoting at the hinge, when the releasable coupling feature is released.

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.
