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. Each section is configured to emit light of different luminescent properties, such as different colors or different color temperatures. The color, color temperature or other characteristics of light emitted by the device is controlled by selectively activating the sections of each LED set.
