Abstract
A solid-state light sourcecompatible with existing sockets normally reserved for filamented lamps may be formed with a hollow baseformed to mechanically and electrically adapt to a socket. A sub-assemblyadapted to cooperate with and fit into the hollow basecomprises a metal corehaving a bulbous bodyand a narrow, depending foot. A circuit boardsubstantially surrounds the metal coreon two sides. The boardis preferably formed from a flexible printed circuit board material capable of sustaining a bend radius of at least 0.25 inches (6 mm). Solid-state light sources, for example, light emitting diodes (LEDs) are mechanically and electrically connected to one side of the circuit board by suitable electrically conductive traces. A glass domecovers the sub-assemblyafter it is inserted into the hollow baseand is sealed thereto.
