Abstract
A modular lighting system for lighting a work area is disclosed. The system includes a power supply with power outlets for powering LED fixtures. The power supply preferably operates at or below a fixed power output level, such as to illuminate the work area using less than 0.2 Watts per square foot of energy. The lighting system also includes an occupancy sensor and/or a light level sensor for controlling lighting levels in the work area in response to detection of a person, ambient light levels and/or a combination thereof. The lighting system can also include computer unit with a micro-processor and a memory unit for running software or firmware the executes lighting programs, stores light usage histories and/or provides system reports to a remote computer by a wireless means and/or over a computer network.
