Illumination control network
View Patent ↗The present invention addresses the problem of providing illumination in a manner that is energy efficient and intelligent. In particular, the present invention uses distributed processing across a network of illuminators to control the illumination for a given environment. The network controls the illumination level and pattern in response to light, sound, and motion. The network may also be trained according to uploaded software behavior modules, and subsets of the network may be organized into groups for illumination control and maintenance reporting.
