Abstract: In a LED lamp having an optically transmissive enclosure and a base connected to the enclosure a plurality of LEDs are operable to emit light when energized through an electrical path from the base. A reflector has an enclosed wall shape and is disposed such that LEDs are mounted inside of and outside of the reflector. The reflector includes a reflective outer surface where in cross-section the reflective outer surface is disposed at an angle relative to the longitudinal axis of the lamp such that the reflective outer surface diverges away from the longitudinal axis as it extends away from the base. The reflective outer surface may be disposed at an angle of between approximately 83 and 89 degrees relative to the plane of the LEDs.
