| Title: |
LED Light Source Mimicking a Filamented Lamp |
| 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) includes 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) includes 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).
