Abstract
PURPOSE: To improve the water proof performance of a lighting equipment consisting of a cylinder, which contains heat radiating components and has an opening water-tightly covered with a cover, and a reflector, both cylinder and reflector being extruded to mould a unit body; and to suppress a temperature rise of light controller parts by using a reflector plate as a heat radiating fin.
