Abstract
Automatic light control system for a Luminaire with a light source and beam forming light collector with and intense hotspot. The Luminaire automatically selects a large aperture when a gobo is selected. When no gobo is selected then a medium aperture is automatically selected. In some embodiments these selections can be overridden. In some embodiments the large and medium aperture are on a non-glass gobo wheel. In further embodiments, when blackout is selected, this wheel automatically advances ½ position or 1 and ½ position so as to support a blackout state of the fixture until a non-blackout condition is selected.
Claims11
An automated multiparameter luminaire comprising:
- a light source generating a light beam with a hotspot;
- a gobo wheel with a plurality of selectable gobos and an no-gobo open position;
- a control system that automatically selects a medium size aperture when the gobo wheel is in the open position and
- automatically selects a large aperture when a gobo is selected.
The automated multiparameter luminaire of claim 3 where some of the gobos are made of a glass.
An automated multiparameter luminaire comprising:
- a light source generating a light beam with a hotspot;
- a gobo wheel with a plurality of selectable gobos and an no-gobo open position;
- an electrical and/or mechanical dimmer;
- and
- when the dim level selected is zero or near zero the control system automatically shifts to a position between gobos positions, whereby the gobo wheel blocks the light beam.
