Abstract
Methods and apparatus for computer-based control of light sources and other devices in a networked lighting system. Conventional light sources may be controlled in combination with LED-based (e.g., variable color) light sources to provide enhanced lighting effects for a variety of space-illumination applications (e.g., residential, office/workplace, retail, commercial, industrial, and outdoor environments). Individual light sources or groups of light sources may be controlled independently of one another based on data transported throughout the network. In one example, one or more other controllable devices (e.g., various actuators, such as relays, switches, motors, etc.) and/or sensors (e.g., heat, light, sound/pressure, or motion sensors) also may be coupled to the network to facilitate automated lighting applications based on a variety of feedback stimuli.
