LED luminaire with light sensor configurations for optical feedback

An LED luminaire comprising;

• an array of LEDs comprising at least one LED in each of a plurality of colors,
• a condenser lens positioned to direct the combined light output of the array of LEDs to a target light guide, and
• an array of light sensors, each light sensor associated with an LED or a partial array of LEDs, each light sensor positioned to intercept and measure at least a portion of the light output of its associated LED or partial array of LEDs, at least first and second ones of the light sensors being adapted to intercept and measure light output from mutually-exclusive subsets of the LEDs.
