Abstract

A luminaire having a plurality of power sockets arranged over its housing is disclosed. In some embodiments, the luminaire includes a driver operatively coupled with all (or some sub-set) of the power sockets and configured to control the light output of a modular solid-state light source operatively interfaced therewith. In some such embodiments, the luminaire also includes a power-line communication (PLC) module configured to output a PLC signal utilized by the driver in controlling the modular light source'"'"'s output. In some other embodiments, the modular light source includes the driver, which may utilize a PLC signal, a command signal received from a remote source, or both, in controlling light output. In some cases, the modular solid-state light sources may allow the luminaire to produce a target light beam distribution utilizing a minimal or otherwise reduced quantity of such light sources, reducing cost and difficulty of installation and commissioning.
