Abstract
An LED (light emitting diode) illumination device that can generate a non-circular light output illumination intensity pattern. The illumination source including a reflector with a conic or conic-like shape. Further, an LED is positioned at approximately 90° with respect to a central axis of the reflector.
Claims22
An illumination source comprising:
- a reflector having at least first and second portions of a reflecting surface, said first portion having a first conic or conic-like shape, and said second portion having a second conic or conic-like shape that differs from the first conic or conic-like shape of said first pattern;
- and
- a light-emitting diode LED positioned at approximately 90° with respect to a central axis of the reflector.
An illumination source comprising:
- means for reflecting a reflector having at least first and second portions of a reflecting surface, said first portion having a first conic or conic-like shape, and said second portion having a second conic or conic-like shape that differs from the first conic or conic-like shape of said first portion;
- and
- a light-emitting diode LED positioned at approximately 90° with respect to a central axis of the means for reflecting.
