In a recent article published by EC&M Magazine, Evergreen Consulting Group’s Tony Adams talks about the evolution of lighting control toward dimming, color tuning, discrete zoning, and application of multiple control strategies in the same space, focusing on luminaire-level lighting controls.
How has the development and introduction of LLLC progressed to date? The lighting industry has successfully managed the evolution from legacy to LED sources over a little more than a dozen years. This transition has brought with it a myriad of control opportunities that were not possible in lighting applications using fluorescent or HID lamps. Solid-state technologies allow us to continuously dim, tune color spectrum, and add numerous control strategies to lighting systems through controllers and sensors. One such lighting system option is luminaire level lighting controls (LLLCs). LLLC technology is a subset of networked lighting control (NLC) systems that includes factory-integrated sensors in each luminaire. These sensors provide occupancy and daylight sensing and wireless, two-way digital communication with (at a minimum) other luminaires in the space, or (at the maximum) broader connectivity via a gateway and the internet, to unite remote spaces such as those found on an educational campus.
