Abstract
A lighting device includes one or more LED modules, each of which includes a group of LED sets positioned on a substrate. Each LED set includes two or more sections, optionally under a single lens. The sections are individually controlled by a controller of the lighting device or an external controller. The beam spread, beam shape, or both of the light emitted by the device may be controlled by selectively activating the sections of each LED set.
