Demonstration

Many of the emerging light sources used for exterior lighting, namely light-emitting diode (LED) and advanced ceramic metal halide (CMH) lamps, provide full-range dimming. Occupancy sensors have provided adaptive lighting controls in exterior parking and area lighting applications, but some applications are not compatible with sensor coverage patterns. In these scenarios, combining dimmable sources with a controller that dims based on time of day can achieve comparable energy savings to utilizing occupancy sensors.

Energy savings can be achieved in corridors and other secondary spaces with an occupancy-based adaptive lighting system. The adaptive lighting system installed at the Latham Square office building is based on Lutron's Energi TriPak solution, a stand-alone platform for adaptive lighting that employs cost-effective wireless control devices and programmable dimming ballasts. 

LD+A – The University of California, Davis, unveiled one of the most advanced outdoor lighting systems in the country this past June. Dubbed the Adaptive Campus Control System, it integrates over 1,600 individually addressed, dimmable LED luminaires with various applications – streetlights, wall packs, area lights, and post tops – into an advanced, wireless lighting controls network.

LD+A ​– California Lighting Technology Center (CLTC) has continued research over the past year to develop and commercialize a next-generation daylight harvesting system with automatic commissioning and increased reliability through the use of two photo sensors. CLTC is working with Wal-Mart to demonstrate the product protytype in a retail store and with Watt Stopper/Legrand to commercialize the system.
