Patent ID: 11232684

Abstract:
A smart luminaire system in which a primary luminaire controls and/or communicates with a set of one or more secondary luminaires may be disposed in a hazardous environment, such as an industrial process plant, manufacturing facility, oil refinery, etc. The primary luminaire may send driving commands to the set of secondary luminaires via an analog portion of a hybrid wired communication interface, and the driving commands may cause a driver of a second luminaire to energize on-board illumination source(s) at various intensities. The primary luminaire may send and/or receive administrative messages to/from the secondary luminaires via a digital portion of its hybrid wired communication interface. The smart luminaire system may be a stand-alone system, or may communicate with a controller or back-end system via a wireless communication interface of the primary luminaire, e.g., to receive control instructions and/or to send consolidated administrative messages on behalf of the smart luminaire system.
