Abstract
A solid state lighting device includes a relatively rigid, thermal dissipation plate with opposite sides, a printed circuit in intimate thermal contact with one side of the plate, at least one LED positioned against and electrically connected to the printed circuit and a shell having a rim secured to the one side of the plate so that the shell substantially covers the LED whereby when the LED is energized, light therefrom radiates into the shell and heat from the LED is conducted away by the plate.
