Abstract

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