Abstract

A luminaire and LED light engine are provided. The luminaire includes the LED light engine and an optical device. The LED light engine includes an LED array and a partial diffuser. The partial diffuser diffuses light that is emitted by LEDs of a selected first subset of LEDs in the LED array and leaves undiffused light that is emitted by LEDs of a second subset of LEDs in the LED array. At least some LEDs are selected for inclusion in the first subset as emitting light that produces poorly blended colors in a light beam emitted by the LED array. The optical device is configured to receive a light beam emitted from the LED light engine and emit a modified light beam.
