Claim of US Patent No. 10,330,293

1. An automated luminaire comprising:a light-emitting diode (LED) source comprising multiple LEDs;
an elongated light integrator, the LED source positioned to emit light into the elongated light integrator, the elongated light integrator configured to internally reflect the light to homogenize the light;
a gobo carrier configured to receive homogenized light from the elongated light integrator, the gobo carrier comprising a set of gobo patterns; and
lenses positioned to receive light passed through the gobo carrier, a first lens coupled to a first light-spill reducing element extending from the first lens toward the LED source, a second lens coupled to a second light-spill reducing element extending from the second lens toward the LED source,
the first light-spill reducing element is positioned within the second light-spill reducing element, and
a distance between each lens and the LED source is adjustable, and each light-spill reducing element is configured to move with the associated lens.
