Simplified Daylight Harvesting

Technology Application

The CLTC is looking for OEM companies interested in collaboration towards the commercialization of the new simplified daylighting control technology, for wide implementation in multiple fixture types and lighting applications

Detailed Technology Description

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.
