Collimated effect luminaire
This specification describes an improved automated luminaire including a plurality of light emitting modules, each including a laser module and an optical module, which expands the width of the laser light beam emitted from the laser module.
1. An automated luminaire comprising:
a base; and
a head, rotatably connected to the base and configured for pan and tilt motion relative to the base, the head comprising a plurality of light emitting modules arranged in two concentric rings, each light emitting module comprising:
a laser module configured to generate a laser light beam; and
an optical module configured to widen an effective diameter of the laser light beam, the optical module comprising one or more moveable lenses that control the effective diameter of the laser light beam.
2. The automated luminaire of claim 1 , wherein each laser module is configured to generate the laser light beam of more than one primary color or a variety of colors based on combinations of the primary colors.
3. The automated luminaire of claim 2 , wherein the primary colors are: red and green, red and blue, green and blue, or red, green and blue.
4. The automated luminaire of claim 1 , wherein each optical module comprises a negative lens followed by a positive lens.
5. The automated luminaire of claim 1 , wherein at least one optical module comprises a holographic lens.
6. The automated luminaire of claim 1 , wherein at least one optical module comprises a gradient beam splitter configured to split the laser light beam into a plurality of individual laser beams.
7. The automated luminaire of claim 1 , wherein a pan and tilt yoke mechanism rotatably connects the head to the base.
8. The automated luminaire of claim 1 , wherein each optical module comprises a negative lens followed by two positive lenses.
9. The automated luminaire of claim 8 , wherein at least one of the two positive lenses of each optical module is configured for controllable motion along an optical axis of the optical module.
