Reflectors and reflector orientation feature to prevent non-qualified trim

摘要

The luminaire includes a light emitting diode (LED) module that includes a heat sink with an outer wall defining a top cavity and a bottom cavity and a mounting flange generally positioned along the bottom of the outer wall. A LED light source is positioned within the bottom cavity and in thermal communication with the heat sink. The bottom surface of the mounting flange includes one or more alignment features or keys extending out from the bottom surface. A trim having a corresponding alignment aperture is matingly engaged by positioning all or a portion of the alignment feature into the alignment aperture to ensure proper orientation of the trim with the LED module and to provide sufficient surface area for good thermal transfer between the heat sink and the trim.

主权项

1. A luminaire comprising:
a light source; a heat sink coupled to the light source, the heat sink comprising:
a top surface and a bottom surface that is opposite to the top surface; and
an alignment feature integral with the heat sink and protruding from the bottom surface of the heat sink; and a trim removably coupled to the heat sink, wherein the trim comprises:
a first aperture configured to receive light from the light source, a second aperture opposite to the first aperture, and a wall disposed between the first and second aperture, wherein an inner surface of the wall defines a light passageway for the light emitted by the light source; and
a top flange extending laterally outward from an upper end of the wall and surrounding the first aperture, the top flange comprising one or more alignment apertures positioned on the top flange and extending through at least a portion of a thickness of the top flange to matingly engage the alignment feature of the heat sink, the alignment aperture corresponding to a size and shape of the alignment feature of the heat sink,
wherein the heat sink is removably coupled to and abuts the trim when the alignment feature of the heat sink matingly engages at least one of the one or more alignment apertures of the trim.
