“Smart” luminaires use integrated sensors to adapt light levels based on available daylight and/or occupancy patterns; “ultra-smart” luminaires function similarly, but they are also capable of communicating with one another through wireless radio frequency (RF) connections. This RF networking allows the luminaires to operate as a larger system. Different luminaire types can be incorporated into the network, including wall packs, post-tops, parking lot luminaires, and streetlights.
Wall packs offer an effective means of illuminating building perimeters, bolstering security and aiding wayfinding, but many are limited in terms of their efficiency, with minimal or nonexistent cutoff. Moreover, because wall packs typically operate in areas with low occupancy rates, they often waste energy fully illuminating vacant spaces for hours at a time every night.
