Sharp LEDs emit light over a 180 degree range, with 50% of the power radiating between +/- 60 degrees. When you want to bring that light to bear in a different pattern, you will need to consider developing a lens, or purchasing one.
There are several sources for lenses and reflectors designed for the SHARP Mini Zenigata, Petite Zenigata, and Double Dome LEDs.
