Lighting device led module with effects for beam spread tuning and beam shaping

摘要

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 LED sections of each LED set. Optionally, the sections may be configured to emit light of different luminescent properties, such as different colors or different color temperatures. In such embodiments, the color, color temperature or other characteristics of light emitted by the device also may be controlled by selectively activating the LED sections of each LED set.
