Abstract
A diode light source system for stage, theatrical and architectural lighting has numerous separate flat, rigid panels for mounting light emitting diodes that emit diode light beams to a common focal area. Each panel is mounted with a group of these diodes, and each has an outer and an inner panel. A screw arrangement selectively positions the panels, with each panel oriented at a selected angle relative to an axis, and with each group of diodes emitting diode light beams transverse to each separate panel. Each inner panel portion is flexibly secured to the screw arrangement. The panels function hold the diodes and act as electrical circuit boards to transmit direct electrical current to the diodes on the panels. The screw arrangement includes an elongated, externally threaded cylinder, with opposed inner and outer ends, rotatably aligned with the axis and mounted on a corresponding internally cylindrical threaded nut.
