An L.E.D. light emitting assembly (20) includes an aluminum heat sink (22) presenting a mounting surface (24) with light emitting diodes (26) disposed thereon. A thermoplastic housing (28) is disposed over the heat sink (22) and presents a top surface (30) facing outwardly. An electronics enclosure (32) is disposed on the top surface (30). A solar shield (34) extends over and spaced from the electronics enclosure (32). The solar shield (34) includes a closed solar top wall (102) and solar side walls (104). The solar shield (34) defines an air inlet (114) adjacent a lower edge (112) of each of the solar side walls (104) and an air outlet (116) above the air inlet (114) at open solar ends (108) thereof for creating a chimney effect to move ambient air into the air inlet (114) and through an air flow space (111) to exit the air outlet (116).
