Daylighting systems are being developed to use sunlight for energy and reduce greenhouse gas emissions. A new control system was designed to manage fluctuations in sunlight intensity in enclosed spaces without direct sunlight access. The system uses solar luminaires, mirrors, and a control algorithm with a microcontroller. Tests in the lab showed that the system works well, with dimming profiles that are perceived correctly and efficient solar luminaire results ranging from 71.60% to 76.44%.
