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