LIGHT CONTROL SYSTEM FOR A LUMINAIRE UTILIZING A LAMP WITH AND INTENSE HOTSPOT
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.
1 . 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.
2 . The automated multiparameter luminaire luminaire of claim 1 where first gobo wheel has rotating gobos.
3 . The automated multiparameter luminaire of claim 3 where some of the gobos are made of a glass.
4 . The automated multiparameter luminaire luminaire of claim 1 where the medium aperture and large aperture are selectable positions on a second gobo wheel and the automatic selection of appertures only occurs if no gobo is selected on the second gobo wheel.
5 . The automated luminaire of claim 4 where the second gobo wheel is an etched metal.
6 . The automated luminaire of claim 4 which also comprises of an electronic and/or mechanical selectable variable dimmer and where when the dim level selected is zero or near zero the control system automatically shifts the second gobo wheel to a position between gobos positions, whereby the gobo wheel blocks the light beam.
7 . The automated luminaire of claim 6 where automatic shift is either ½ or 1½ position(s).
8 . The automated luminaire of claim 6 where when the dimmer level is raised from the zero or near zero, the second gobo wheel automatically returns to it last known full position.
9 . 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.
10 . The automated luminaire of claim 9 where automatic shift is either ½ or 1½ position(s).
11 . The automated luminaire of claim 9 where when the dimmer level is raised from the zero or near zero selection, the second gobo wheel automatically returns to it last known full position.
