LED light source mimicking a filamented lamp

摘要

A solid-state light source ( 10 ) that is compatible with the existing sockets normally reserved for filamented lamps ( 100 ). The solid-state light source ( 10 ) comprises a hollow base ( 12 ) formed to mechanically and electrically adapt to an existing socket normally reserved for lamps ( 100 ). A sub-assembly ( 14 ) is adapted to cooperate with and fit into the hollow base ( 12 ). The sub-assembly ( 14 ) comprises a circuit board ( 16 ) with a plurality of solid-state light sources ( 18 ) mechanically and electrically connected to one side ( 20 ) of the circuit board. Two electrical contacts ( 22, 24 ) are positioned on the other side ( 26 ) of the circuit board for connection to an electrical circuit. A light pipe ( 28 ) covers the plurality of light sources ( 18 ) and extends away therefrom to a terminal end ( 30 ). A light radiator ( 34 ) is affixed to the terminal end ( 30 ) and a light-opaque shroud ( 33 ) surrounds the light pipe ( 32 ) to keep all of the light generated by the solid-state light source within the light pipe ( 32 ) to exit out of the light radiator ( 34 ).
