Abstract:
1. An LED lamp comprising: a housing with an interior wall defining a cavity providing an opening facing a forward direction, said cavity having a back wall, said housing including a heat sink extending on an exterior side of said back wall; a circuit board mounted in said cavity adjacent said back wall in thermal communication therewith; an LED light source mounted on said back wall and surrounded by said circuit board and projecting light in said forward direction and sideways directions up to 90 degrees from said forward direction; a reflector including a paraboloidal reflective surface and having a forward opening and a rear opening therein, said reflector being positioned in said cavity, said LED light source positioned in said rear opening to face said reflective surface, said reflector directing intercepted light from said LED; a lens coupling with said housing to enclose said circuit board, LED light source and reflector, said lens having a first optical refractive element arranged around a peripheral edge and having a second optical refractive element centrally located on said lens; said first optical refractive element including a plurality of flute lenses and said second optical refractive element comprising a concavo-convex lens; and a plug coupling formed on said exterior of said housing for receipt of an electrical supply lead to couple electric power to said circuit board.
