Abstract

An LED module and luminaire are provided. The LED module includes an LED circuit board having an array of LEDs powered by an electrical connector. The array of LEDs includes two or more pluralities of LEDs. The LEDs of a first plurality are rotated relative to the LEDs of a second plurality. The rotation amount is not an integer multiple of 90°. The LEDs of the first plurality are not rotated relative to each other, and the LEDs of the second plurality are not rotated relative to each other. The LED module can be removed from an optical system of the luminaire by electrically uncoupling the LED circuit board and mechanically uncoupling the LED module from the luminaire without removing other elements of the optical system from the luminaire.
