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.
