Abstract
A lamp assembly adapted to cast shadow-free illumination over an area. Typically, a lamp assembly includes a plurality of light modules that are disposed in a spaced apart relationship over an area. Desirably, the lamp assembly is arranged to aim the light output of each module for overlapping summation on a target footprint. Modules generally each include a LED light source, a parabolic reflecting mirror arranged to direct light from the LED, a TIR collimating lens disposed at a distal end of the mirror, and a stray light tube disposed between the LED and a dispersing lens element.
