Abstract:
1. A light device comprising: (a) a printed circuit board on which a plurality of light emitting diodes (LEDs) are mounted, a light intensity distribution output from the LEDs having 50% intensity values at about +/−60 degrees; (b) a master reflector including a plurality of individual reflectors, one of said plurality of individual reflectors configured to surround at least one of the plurality of LEDs, each individual reflector including an opening through which a respective at least one of the plurality of LEDs can pass, and including reflective surfaces as sidewalls of the opening surrounding the respective at least one of the plurality of LEDs; and wherein one of the LEDs is placed in a center of a respective individual reflector at a position such that light output from the one LED beyond +/−50 degrees impinges on the reflective sidewalls to be reflected, and each individual reflector modifies a light intensity portion of the respective surrounded LED to provide a light output in which an intensity value near 0 degrees is about one-half intensity peaks beyond 20 degrees and beyond −20 degrees.
