Abstract (en)

An optical assembly and a luminaire with extreme cutoff beam control optics. The optical assembly includes a base, a plurality of lenses, a plurality of light emitting diodes (LED) positioned to emit light into the lenses, and a reflector having a reflective surface disposed adjacent at least one of the plurality of LEDs. The optical axis of one or more of the LEDs may be offset from a central axis of the respective lens in which it emits light. The reflective surface of the reflector may extend from the base over the one or more of the LEDs and beyond the optical axis of the one or more LEDs to direct light in a desired direction or toward a selected area (e.g., a street) and cut off light directed in an undesirable direction or area (e.g., a house).
