Aerodynamic LED Light Fixture

A pole-mounted light fixture comprising:

• two major principal axes in a fixture plane, the dimensions of the fixture in planes parallel to its third principal axis being substantially smaller than the largest dimensions parallel to the fixture plane;
• a first outer side comprising a first central portion and a first edge-adjacent portion;
• an opposite second outer side comprising (a) a second central portion substantially aligned with the first central portion and encompassing a light-emitting region, the light-emitting region including at least one LED-array module supported by an LED heat sink open for air/water-flow, and (b) a second edge-adjacent portion having a boundary with the second central portion, the boundary defining a reference plane;
• a pole-mounting assembly for attaching the fixture to a light pole;
• the first and second edge-adjacent portions converging toward each other at positions progressively closer to the perimetrical edge to form aerodynamic-drag-reducing cross-sectional profiles transverse to the fixture plane and extending in substantially all fixture-plane directions from the intersection of its two major principal axes, the first and second edge-adjacent portions together having aspect ratios of about 2 or less;
• and
• the greatest distance perpendicular to the fixture plane between the first central portion and the reference plane is no more than 50% greater than the smallest distance therebetween.
