Claim of US Patent No. 10,133,080

1. A luminaire comprising:a head;
a positioning mechanism, coupled to the head and configured to rotate the head in at least one axis; and
a light source, coupled to the head and configured to emit a beam of light,
wherein the light source comprises:
a first array of light emitting diodes (LEDs), the first array comprising a first plurality of sets of LEDs, each set of the first plurality of sets of LEDs having a different associated peak wavelength;
a second array of LEDs, the second array comprising a second plurality of sets of LEDs, each set of the second plurality of sets of LEDs having a different associated peak wavelength; and
a dichroic filter configured to combine light from the first array of LEDs with light from the second array of LEDs to produce the emitted beam of light, wherein filter characteristics of the dichroic filter are selected to maximize transmission of the light from the first plurality of sets of LEDs and to maximize reflection of the light from the second plurality of sets of LEDs.
