Abstract
LED lampincludes a housing, a mounting base, a light engine (LE), light-transmissive covercircumscribing the LE, and reflector. The LE comprises a plurality of top-emitting LED packages (TE-LED packages) mounted on planar upper surfaceof PC board, each configured to emit light having an angular distribution centered around a principal light-emitting direction (PLED) normal to an emission face. A first setof TE-LEDs is mounted with its PLED perpendicular to PCBand a second setof TE-LEDs is mounted to the PCB with its PLED orthogonal to that of the first setof TE-LEDs and parallel to upper surface. Reflectordisposed below LEreflects light towards cover. A polar light distribution of light emitted from LED lampis omnidirectional and is Energy Star compliant.
