Abstract
A light source for stage, theatrical and architectural lighting that includes a plurality of separate flat and rigid panels for mounting a plurality of light emitting diodes that emit light beams to a common focus area, each separate panel having grouped diodes of the plurality of diodes, and having inner and outer panel portions. A housing for the panels has a center base portion and an aperture/plane rim transverse to an axis aligned with the center base portion. A first connection flexibly secures each outer panel portion to the rim. A screw positions the panels at selected positions wherein each is oriented at a selected angle relative to the axis and the diodes emit light beams transverse to each separate panel. A second connection flexibly secures each inner panel portion to the screw. The panels hold the diodes and include circuit boards for powering the diodes. The screw is elongated and rotatably aligned with the axis of and threaded to a nut at its outer end portion, and its inner end portion being rotatably mounted to the center base portion.
