Simplified Daylight Harvesting

With support from the Public Interest Energy Research (PIER) program of the California Energy Commission (CEC) the California Lighting Technology Center (CLTC) has developed the foundations for a simplified on/off and stepped dimming control system for bi-level lighting applications. The new simplified daylighting control system is composed of a microcontroller a photo sensor an optional occupancy sensor and optional user controls. These components can be integrated into single product/units or be combined through wired and/or wireless communications for a variety of products and systems. The new technology offers auto- and continuous calibration along with user adjustable on/off set points for light switching. California utility members of the CLTC Advisory Council (PG&E SCE SDGE and SMUD) have reviewed the new technology and have expressed strong interest in supporting demonstrations of emerging technologies. Applications: Multiple fixture types and lighting applications.
