Abstract
Lamp including an array of LEDs disposed at or near the focus of a reflecting optic having multiple segments with different aiming angles (i.e. the angle corresponding to a reflected beam output direction), and a driver circuit for discretely activating some of the LEDs in the array. The angular distribution of the output light beam (e.g., the beam divergence) is adjusted by selectively changing the currents supplied to the LEDs.
