Abstract
A lighting system aperture mechanism formed by a movable carriage including a frame with openings for mechanically formed or electronic pattern apertures. The frame is moved to position a selected opening around a beam of light and the pattern aperture disposed within the selected opening may be rotated as desired to produce special effect patterns in the beam of light.
Claims23
A selectable aperture apparatus for use in a stage lighting system or the like, comprising:
- base means;
- means for movably supporting said base means and having formed therein a first opening and a second opening;
- an electronic pattern aperture means disposed within said first opening in said supporting means for selectively forming a plurality of opaque patterns for modifying a beam of light travelling along an optical axis passed through said electronic pattern aperture means, said second opening being capable of allowing the transmission of a beam of light at substantially full intensity, with no significant attenuation therein;
- and
- drive means for controllably moving said supporting means in such a manner so that said first and second openings are selectively intersected by said optical axis.
