    Abstract: An LED light fixture including at least one LED light source thermally coupled to a heat-conductive structure. The heat-conductive structure having an LED-supporting region and heat-dissipating surfaces extending away therefrom. The at least one LED light source is thermally coupled to the LED-supporting region. The heat-conductive structure defines venting apertures bordering the at least one LED light source to facilitate ambient fluid flow to and from the heat-dissipating surfaces. In some embodiments, the LED light fixture includes a protrusion extending into a corresponding one of the venting apertures and oriented to direct air flow. In certain embodiments, the heat-conductive structure defines a plurality of venting apertures adjacent the at least one LED light source, the heat-dissipating surfaces include fins increasing in height at positions adjacent to the at least one of the venting apertures.

    Abstract: A direct troffer-style fixture for solid state light sources and pan structures for use in these fixtures. The fixture comprises a door frame assembly that is attached to the pan. The pan housing is defined by a base and two angled side walls. End caps are attached to the side walls. End reflectors extend at an angle away from the end caps and attach to the base. The end caps, the end reflectors, and the base define compartments at both ends of the housing in which components can be housed. A light board is attached to the base using alignment holes in the base and cutout portions of the end reflectors. The multifunctional end reflectors retain elements within the compartments, provide added structural stability to the pan, aid in aligning a light board, and they reflect light that impinges on them toward the open end of the fixture.
