AERODYNAMIC LED FLOODLIGHT FIXTURE Abstract An LED floodlight fixture (10) having two major principal axes in a fixture plane (42), the dimensions parallel to the fixtures third principal axis being substantially smaller than the largest dimensions parallel to the fixture plane (42). The fixture (10) is characterized by a first outer surface (18) which has a first central portion (20) and a first edge-adjacent portion (22), an opposite second outer surface (24) which has a second central portion (44) substantially aligned with the first central portion (20) and encompassing a light-emitting region (26) and a second edge-adjacent portion (28) having a boundary (46) with the second central portion (44) such boundary (46) defining a reference plane (34), the first and second edge-adjacent portions (22, 28) meet at a perimetrical edge (30). The first and second central portions (20, 44) each extend across at least 25% of the area within the perimetrical edge (30). The first and second edge adjacent portions (22, 28) form aerodynamic-drag-reducing cross-sectional profiles (32) transverse to the fixture plane (42) and extend in substantially all in-fixture plane (42) directions, the greatest dimension between the first central portion (20) and the reference plane (34) is no more than 50% greater than the smallest dimension therebetween. |
