Method and system for lighting control and monitoring
First Claim
1. A lighting-control system comprising:
- two or more lighting fixtures, each containing one or more light-emitting-diode-based lighting elements;
two or more lighting-fixture management units, each of the lighting fixtures including a lighting-fixture management unit, each lighting-fixture management unit including a light-emitting-diode-based-luminaire driver and storing control information and status information and controlling the intensity of light emitted by the light-emitting-diode-based lighting elements, over a range of intensities, within the lighting-fixture that contains the lighting-fixture management unit according to the stored control information; and
a router that provides a user interface for creation and modification of operational schedules for automated control of the light-emitting-diode-based lighting elements within the lighting fixtures and that communicates with lighting-fixture management units, using a first communications medium between the router and at least one lighting-fixture management unit and additionally by an inter-lighting-fixture-management-unit communications medium, in order to transmit control information to the lighting-fixture management units and receive status information from the lighting-fixture management units;
wherein lighting-fixture management units include bridge lighting-fixture management units and end-point lighting-fixture management units;
wherein each end-point lighting-fixture management unit controls intensity of light emission from light-emitting-diode-based lighting elements within the lighting fixture that contains the end-point lighting-fixture management unit, according to an operational schedule and additional control directives stored within the end-point lighting-fixture management unit;
wherein each end-point lighting-fixture management unit monitors input from one or more sensors and generates events, based on sensor input; and
wherein each end-point lighting-fixture management unit collects and stores status information related to operation of components within the lighting fixture that contains the end-point lighting-fixture management unit.

Abstract
Embodiments of the present invention are directed to control of lighting systems at individual-light-fixture, local, regional, and larger-geographical-area levels. One embodiment of the present invention comprises a hierarchical lighting-control system including an automated network-control center that may control up to many millions of individual lighting fixtures and lighting elements, regional routers interconnected to the network-control center or network-control centers by public communications networks, each of which controls hundreds to thousands of individual light fixtures, and light-management units, interconnected to regional routers by radio-frequency communications and/or power-line communications, each of which controls components within a lighting fixture, including lighting elements, LED-luminaire drivers, sensors, and other devices.
