Beschreibung
Zusammenfassung:	An LED light fixture including a heat-conductive overstructure having upper and lower surfaces and a plurality of upwardly-protruding elongate fins which extend along the upper surface adjacent to at least one opening through the fixture permitting air flow from beneath the lower surface to above the upper surface. An LED light source is secured with respect to the lower surface. The fins have heights which gradually increase toward fin-ends proximal to the at least one opening.
