ABSTRACT:
A technique for collimating light from a Light Emitting Diode (LED) device involves emitting light from an LED die, collimating the light with a parabolic reflector, and further collimating the light with a lens. A device constructed according to the technique includes an LED die, a lens for collimating light, and a parabolic reflector for collimating light from the LED die toward the lens.
