Claim of US Patent No. 10,408,402

1. An automated multiparameter luminaire, comprising:a multi-die light-emitting diode (LED) light source configured to emit a first light beam;
an elongated total internal reflection (TIR) homogenizer having parallel sides, optically coupled to the multi-die LED light source and configured to receive the first light beam and emit a second light beam;
a zoom lens system, configured to receive the second light beam without passing through any intervening lenses and to emit a third light beam, the zoom lens system further configured to alter one or more of a focus, beam angle, or zoom of the third light beam; and
an optical effect system positioned between the elongated TIR homogenizer and the zoom lens system, the optical effect system comprising a prism configured (i) to be moved to a first position in the second light beam and to a second position out of the second light beam, and (ii) to rotate within the second light beam while in the first position.
