Abstract
Principles of nonimaging optics, imaging optics, etendue matching, and the Constant Brightness Theorem are used to provide an ultra-efficient solid state lighting optical system for stage and theatrical profile spotlights. Used in combination, an array of high brightness light emitting diodes, a nonimaging optical transform element, and an image forming optical element enable the design of profile spotlights capable of high brightness, low electrical power consumption, sharp gobo imaging, adjustable beam intensity profiles, and use of current industry standard accessories and elements, such as gobos, blades and irises.
