The present disclosure relates to a lighting fixture that includes a driver module and at least one other module that provides a lighting fixture function, such as a sensor function, lighting network communication function, gateway function, and the like. The driver module communicates with the other modules in a master/slave scheme over a communication bus. The driver module is configured as a slave communication device, and the other modules are configured as master communication devices. As such, the other modules may initiate communications with the driver to send information to or retrieve information from the driver module.

A lighting system and method for generating an output light beam representative of a target natural light are provided. The lighting system includes a plurality of solid-state light emitters each emitting a light sub-beam having an individual spectrum. The individual spectra of the solid-state light emitters collectively cover a visible portion of the natural light spectral profile and exclude infrared and ultraviolet components. The lighting system further includes a combining assembly combining the light sub-beams into the output light beam. A control module controls an intensity of the light sub-beam from each of the solid-state light emitters such that the resulting combined spectral profile of the output light beam is representative of a natural light spectral profile of the target natural light over its visible portion.

Solid state light fixtures include a plurality of blue-shifted-yellow/green light emitting diode (“LED”) packages and a plurality of blue-shifted-red LED packages, where the solid state light fixture emits light having a correlated color temperature of between 1800 K and 5500 K, a CRI value of between 80 and 99, a CRI R9 value of between 15 and 75, and a Qg value of between 90 and 110 when the blue-shifted-yellow/green LED packages and the blue-shifted-red LED packages are operating at steady-state operating temperatures of at least 80° C.

An LED luminaire comprising a housing, a chamber with an internal cavity formed by a wall, a plurality of LED lamps mounted around at least a portion of the inner wall surface, and a plurality of heat sink elements mounted around at least a portion of the outer wall surface.
