Abstract
A solid-state light source () that is compatible with the existing sockets normally reserved for filamented lamps (). The solid-state light source () includes a hollow base () formed to mechanically and electrically adapt to an existing socket normally reserved for lamps (). A sub-assembly () is adapted to cooperate with and fit into the hollow base (). The sub-assembly () includes a circuit board () with a plurality of solid-state light sources () mechanically and electrically connected to one side () of the circuit board. Two electrical contacts () are positioned on the other side () of the circuit board for connection to an electrical circuit. A light pipe () covers the plurality of light sources () and extends away therefrom to a terminal end (). A light radiator () is affixed to the terminal end () and a light-opaque shroud () surrounds the light pipe () to keep all of the light generated by the solid-state light source within the light pipe () to exit out of the light radiator ().
