Abstract
Disclosed is an LED light source automated luminaire with a multi-sided elongated light collimator/mixer/integrator with receiving lens and output lens both with spill shields and where the receiving spill shield is nesting in the output spill shield. The elongated integrator has a square input cross-section and a hexagon or octagon output cross section and is tapered so that the input cross section is smaller than the output cross section.
Claims19
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.
