Abstract: A T-LED light engine that provides up-light and down light. The T-LED has a top lens that emits a “bat-wing” light pattern and a bottom lens that emits a Lambertion light pattern. The T-LED light engine has an internal or on-board driver unit and/or on-board control unit. End caps of the T-LED light engine can be removed to service or replace internal components. The end caps have two-pin contact configurations that mate with tombstone style sockets or connectors and/or have bridge connector for connecting multiple T-LED light engines in series.

Abstract: A street light includes a pole and a head attached to the pole. The head includes a light emitting element comprising a plurality of solid state light emitting devices, an optical element, and a reflector configured to reflect light emitted by the solid state light emitting devices to the optical element to produce a light distribution pattern from the head. The light emitted from the solid state emitting devices may be Lambertian patterned light. The Lambertian patterned light may be used to illuminate the reflector. The reflector may be used to transform the Lambertian patterned light to collimated light and direct the collimated light towards the optical element. The optical element may be configured to produce the light distribution pattern from the collimated light.
