Lighting Enabled Systems and Applications: A Vision Way Beyond Seeing

LESA: A Vision Way Beyond Seeing, an article which appeared in the May 17, 2016 online edition of West Coast Lighting Insider, highlights the work of the ERC.  In the future, personalized lighting will interact with our presence, our environment and our activities. Lighting will change color, brightness and directionality, all the while transmitting data to our cellphones and wearable tech, networked with the Internet of Things (IoT). Implementing this vision is the purpose of the Smart Lighting Engineering Research Center, newly rebranded as the Lighting Enabled Systems & Applications Engineering Research Center (LESA ERC).
