LED light source mimicking a filamented lamp
First Claim
1. A solid-state light source compatible with existing sockets normally reserved for filamented lamps comprising:
- a hollow base formed to mechanically and electrically adapt to a socket; and
a sub-assembly adapted to cooperate with and fit into said hollow base, said sub-assembly comprising;
a circuit board;
a plurality of solid-state light sources mechanically and electrically connected to one side of said circuit board;
two electrical contacts positioned on the other side of said circuit board for connection to an electrical circuit;
a light pipe covering said plurality of light sources and extending away therefrom to a terminal end;
a light radiator affixed to said terminal end; and
a light-opaque shroud surrounding said light pipe.

Abstract
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).

9. A solid-state light source compatible with an existing socket normally reserved for a known filamented lamp, comprising:
-
a base formed to mechanically and electrically adapt to a socket; and
a sub-assembly adapted to cooperate with and fit into said base, said sub-assembly comprising;
a plurality of solid-state light sources mechanically supported in the base;
two electrical contacts electrically connected to the solid-state light sources and extending to exterior electrical contacts as adapted to the socket;
a light pipe receiving input light from said plurality of light sources and extending away therefrom to a terminal end;
a light radiator affixed to said terminal end, the light radiator being shaped to radiate light that mimics the radiation of a filament; and
a light-opaque shroud substantially surrounding said light pipe between the light sources and the light radiator.
