A solid state lamp includes a connector and a bulb portion with multiple strips.

A lamp includes an extended planar light source, and an optical element arranged with the light source, wherein the optical element comprises an outer surface having an indented cusp substantially over the light source. A lamp includes an extended planar light source, and an optical element arranged with the light source, wherein the optical element comprises an outer surface having a portion at a peripheral edge comprising a curvature configured to redirect light emitted from the light source by total internal reflection.

A lighting apparatus is provided having one or more light emitting diodes arranged in a row. The light emitting diodes may be supported by an elongated body. The elongated body may comprise an optical element formed from an at least partially optically transmissive material. The lighting apparatus has two ends and may have electrical connectors at the ends.
