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 lighting device includes a substrate, a light emitting diode (LED) array mounted on a first surface of the substrate, and circuit components mounted on the first surface of the substrate and coupled to the LED array wherein the circuit components are adapted to control electrical power applied to the LED array. A heat exchanger is mounted on a second surface of the substrate and a reflector is disposed about the LED array wherein the reflector has a reflection surface that is convex on a first side of an inflection locus and concave on a second side of the inflection locus, and wherein the first side of the inflection locus is proximate the LED array. A diffuser is adjacent the second side of the inflection locus of the reflector.

Abstract: An LED light fixture including a plurality of upwardly-protruding elongate fins extending therealong from distal fin-ends to proximal fin-ends adjacent to upward-flow openings through the fixture, the fins defining horizontal between-fin channels open at the distal fin-ends, and a plurality of flow-interrupters between adjacent fins changing air flow along the channels. The flow-interrupters may be less than half the heights of their respective between-fin channels and may be mounting bosses to serve the further purpose of facilitating assembly of the fixture.

Abstract: A mounting assembly for securing a light fixture to a static structure. The mounting assembly includes a bar and a securing member which has a bar-gripping portion and an arm portion extending from the bar-gripping portion and attachable to the static structure. The bar is secured with respect to a main body portion of the light fixture. The bar has an axis. The arm portion has an arm axis which is substantially orthogonal to the bar axis. In another aspect of this invention, the mounting assembly includes a fixture-holding portion and an arm portion secured to the fixture-holding portion. The fixture-holding portion is secured with respect to the light fixture. The arm portion configured for selective attachment to a substantially cylindrical static structure and a substantially planar surface.
