Abstract
A light fixture (50), comprising: an electronics housing (51); first and second heat sink structures (52, 54, 56, 58, 60, 62) coupled to the electronics housing, wherein each heat sink structure of the first and second heat sink structures is defined at least in part by a heat sink outer arc (64) having first and second end points (72, 74), and wherein each heat sink structure is further defined at least in part by two heat sink radii (66, 68) extending from the first and second end points, respectively, to a center point (P) of the light fixture; first and second light sources (53); at least two lenses (106, 108, 110, 112, 114, 116) comprising a first lens attached to the first heat sink structure and covering the first light source and a second lens attached to the second heat sink structure and covering the second light source, wherein each lens of the first and second lenses is defined at least in part by a lens outer arc (120) having first and second end points (128, 130), wherein each lens is further defined at least in part by two lens radii (122, 124) extending from the first and second end points, respectively, to a point (PI) that is different than the center point of the…
