A lamp using solid-state light emitting sources is configured to be used in a conventional socket. The lamp includes a flexible substrate on which are mounted a plurality of light emitting sources, such as light emitting diodes (LEDs) in spaced-apart array. In one embodiment, a flexible substrate configured as a generally rectangular panel formed into a cylindrical shape includes a plurality of conductive traces to which the LEDs are connected both mechanically and electrically. The flexible substrate is then enclosed within a light transmissive translucent cover that is attached to a base in which is disposed a power supply. The base is shaped and configured to be threaded into a conventional incandescent light socket and includes a center terminal through which AC line power is supplied to the power supply. The power supply provides an appropriate voltage and current to energize the light sources so that they produce a white light that is emitted radially outward around a longitudinal axis of the lamp. In a different embodiment, the light sources are mounted on a flexible substrate formed as a strand or thread that is wound in a helix around a cylindrical support. The light sources are also provided on a flap that covers the end of the cylinder so that light is emitted through the top or end of the cover. Also included is a solid-state lamp adapted to work in a conventional three-way socket.
