Patent number: 8632213Abstract: A lighting fixture including a housing having an inner surface and open first and second ends formed by closed-perimeter first and second edges, respectively, and defining an elongate top-to-bottom open space. The first end forms a light opening. A light-emitting arrangement is positioned in the open space. The arrangement includes (a) at least one light emitter positioned for directing light toward the light opening and (b) a heat sink connected to the light emitter(s). The heat sink preferably has a plurality of heat-dissipation surfaces extending away from the light opening. The heat sink is configured and positioned in the open space to facilitate fluid-flow therealong and through the open space.Type: GrantFiled: May 5, 2011Date of Patent: January 21, 2014Assignee: Cree, Inc.Inventors: Steven Patkus, Bernd Sieberth, Brian Kinnune
