Abstract
Presented is a multiparameter automated luminaire comprised of a plurality of light engine modules, a plurality of which by design homogenize light emitted by its light sources more fully than at least one of the light engine modules, which is intentionally designed to noticeably not fully homogenize the light emitted by its light sources. In the preferred embodiment, the non homogenizing light engine module also includes light modulators optionally engagable to more fully homogenize the light output from that light engine module.
Claims20
An automated luminaire comprising:
- a light emitting diode (LED) array source configured to emit a plurality of colored light beams;
- a light guide optically coupled to the LED array source and configured to receive the plurality of colored light beams emitted by the LED array source and to emit a partially homogenized light beam that includes at least some visible separation of the received plurality of colored light beams;
- and
- a lens optically coupled to the light guide and configured to receive the partially homogenized light beam and to move along an optical axis of the light guide, the lens being configured to project a pattern of the visibly separated colored light beams in the partially homogenized light beam, the pattern spreading and contracting as the lens moves along the optical axis of the light guide.

An automated luminaire, comprising:
- a first light engine module comprising:
- a first light emitting diode (LED) array source configured to emit a first plurality of colored light beams;
- a first light guide optically coupled to the first LED array source and configured to receive the first plurality of colored light beams emitted by the first LED array source and emit a first homogenized light beam, the first homogenized light beam including visible separation of at least some of the received first plurality of colored light beams;
- and
- a first lens optically coupled to the first light guide and configured to receive the first homogenized light beam and to move along an optical axis of the first light guide, the first lens being configured to project a pattern of the visibly separated colored light beams in the first homogenized light beam, the pattern changing size as the first lens moves along the optical axis of the first light guide;
- and
- a plurality of second light engine modules, each second light engine module comprising:
- a second LED array source configured to emit a second plurality of colored light beams;
- a second light guide optically coupled to the second LED array source and configured to receive the second plurality of colored light beams emitted by the second LED array source and emit a second homogenized light beam, wherein the second homogenized light beam includes less visible separation of the received second plurality of colored light beams than the visible separation of the first homogenized light beam;
- and
- a second lens optically coupled to the second light guide and configured to receive the second homogenized light beam and to move along an optical axis of the second light guide, wherein the second lens projects a light beam having a beam angle determined by a distance of the second lens from the second light guide.
