a u201c pope 39 s hat u201d the solid angle zone of the light served by surfaces 51 and 70 takes the energy from the primary directed beam of the led 39 s u2018 curb u2019 side and redirects it toward the u2018 street u2019 side optional surface 53 is a blended contour between surfaces 52 and 58 surface 57 is mirrored across intersection 54 in fig2 and is lofted in the embodiment shown to redirect the centerline energy of the led down the u2018 curb u2019 direction surface 57 allows for very high efficiency for the lens 21 in both the street and the curb side of its light pattern in fig2 surface 52 is depicted as an azimuthally symmetric surfaced defined through an azimuthal angle of about 185 degrees while this is desirable for some applications it is well within the scope of the invention that surface 52 and its adjacent surfaces may be azimuthally asymmetric surface 59 is an optional feature to redirect the centerline energy of the led surface 59 can take of many different forms to allow the designer freedom to shape the beam in the embodiment of fig2 26 the shape of surface 59 is utilized to allow for a continuation of the light spreading effect of surface 52 but constrained to keep the thickness of the device 10 within manufacturing capabilities in fig2 interface 62 between dome 19 and lens 21 is utilized if the lens 21 is a molded optic separate from the led if the lens 21 of the.
