LUMINAIRE WITH THERMALLY-INSULATING FIN GUARDS AND ASSOCIATED METHODS

摘要

A luminaire comprising a base, an optic attached to the base, a heat sink integrally molded within the base, and a heat-generating element comprising a light source in thermal communication with the heat sink. The light source may be positioned such that light is emitted thereby into an optical chamber defined by the first housing. A second housing may comprise channels formed by opposing pairs of fin guards. The heat sink may comprise fin assemblies connected along a perimeter of a heat-generating element contacting portion of the heat sink. An enclosable region may be formed between fin guards that has a knurled portion on an outer surface thereof. A proximal edge of each fin assembly may be positioned adjacent to an outer surface of the first housing, and a distal edge thereof may be positioned coextensive with a respective channel and substantially exposed to the environment external to the luminaire.

主权项

1. A luminaire comprising:
a base comprising a first housing and a second housing, the first housing having an inner surface and an outer surface, and the second housing comprising a head that includes an aperture and a plurality of fin guards that include
a first two of the plurality of fin guards, defined as a spaced pair, characterized by an enclosable region formed therebetween, anda second two of the plurality of fin guards, defined as an opposing pair, characterized by a channel formed therebetween; a heat sink comprising a heat-generating element contacting portion and a plurality of fin assemblies connected to a perimeter of the heat-generating element contacting portion; and a heat-generating element positioned in thermal communication with the heat-generating element contacting portion of the heat sink; and wherein the outer surface of the enclosable region located between the plurality of fin guards has a knurled portion configured as a luminaire grip. wherein an inner surface of the heat sink is positioned adjacent to the outer surface of the first housing; and wherein at least one of the plurality of fin assemblies of the heat sink is configured to project through the aperture in the head and into the channel in the second housing so that a distal edge of the at least one fin assembly is exposed to the environment external to the luminaire.
