Patent Images
1. A light bulb comprising:
- an elongated structure having at least one longitudinal side;
a plurality of light emitting diodes secured to said at least one longitudinal side, said light emitting diodes arranged in a generally linear configuration;
a tubular shell having a wall surrounding an interior void, said elongated structure positioned at least partially in said interior void;
an endcap covering an end of said tubular shell, said endcap having a support member adapted to engage a recessed double contact light bulb socket, said endcap having a pair of electrical conductors extending into a socket formed in said endcap, said socket adapted to receive a power supply plug; and
a pair of electrical leads coupled to said pair of electrical conductors, and said light emitting diodes having wiring coupled to at least one of said electrical leads.
