Abstract

This paper presents an energy-efficient solution for the smart light-emitting diode (LED) lighting system, which simultaneously provides minimal energy consumption and satisfies users’ illuminance requirements. Typical office space is illuminated by artificial light received from dimmable LED lamps, as well as daylight coming from external sources, i.e., the sunlight. Besides the possibility to dim LED lamps resulting in reduced LED output power, total illumination intensity at users’ location can be managed by reducing overall daylight. The idea to decrease daylight intensity is realized by option to dim the windows in order to properly exploit external lighting. Simulation results show that the proposed algorithm provides greater level of users’ satisfaction related to illuminance requirements.
