Abstract
A luminaire includes a housing, a heat sink, and a light assembly. The housing includes a pair of elongated, parallel legs and a cross-member extending between the legs. The cross-member defines a first surface and a second surface opposite the first surface, and the first surface includes an opening. The heat sink is coupled to the housing proximate the second surface of the cross-member. The heat sink is positioned between the legs and the heat sink includes a plate and a fin array. The plate defines a first surface and a second surface opposite the first surface, and the fin array including a plurality of fins protruding from the first surface. The light assembly is coupled to the second surface of the heat sink and includes at least one light-emitting element (e.g., a light-emitting diode or LED).
Claims29
A luminaire comprising:
- a housing including a pair of elongated, parallel legs and a cross-member extending between the legs, the cross-member defining a first surface and a second surface spaced apart from the first surface, the first surface including an opening, each leg including an inner surface and a lower extent and at least one groove extending between the inner surface and the lower extent;
- a heat sink coupled to the housing and positioned proximate the second surface of the cross-member, the heat sink positioned between the inner surface of the legs, the heat sink including a plate and a fin array, the plate defining a first surface and a second surface opposite the first surface, the fin array including a plurality of fins protruding from the first surface, and the fin array defining at least one air flow channel having an inlet and an outlet;
- and
- a light assembly coupled to the second surface of the heat sink, the light assembly including at least one light-emitting element,
- wherein the groove directs air flow from below the housing toward the at least one air flow channel, and
- wherein each leg includes an outer surface facing away from the other leg, at least one of the outer surfaces includes an opening to permit access to an internal compartment of the housing.

A luminaire comprising:
- a housing including a first portion and a second portion, the first portion having a first surface and a second surface spaced apart from the first surface, the first portion defining a first axis extending between the first surface and the second surface, the first surface including an opening configured to receive an electrical conduit in electrical communication with a power source, the first surface defining an uppermost portion of the housing;
- a heat sink supported by the housing and positioned proximate the second surface, the heat sink including a plate and a fin array protruding from a surface of the plate, the plate having a first end, a second end, a first edge extending between the first end and the second end, and a second edge extending between the first end and the second end, the fin array defining at least one air flow channel having an inlet positioned proximate the first edge of the plate and an outlet positioned proximate one of the first end and the second end of the plate;
- a light assembly including at least one light-emitting element and a lens, the light assembly coupled to a surface of the plate opposite the fin array,
- wherein the first portion of the housing includes a first side wall and a second side wall, the first side wall and the second side wall extending between the first surface and the second surface,
- wherein the heat sink defines a heat sink axis extending between the first end of the plate and the second end of the plate, and
- wherein the first end of the heat sink extends beyond the first side wall of the housing and the second end of the heat sink plate extends beyond the second side wall of the housing.
