Fuzzy Logic for Lighting System in Eco Airport Passenger Waiting Room

Abstract

The lighting system is one of the great considerations in the eco airport buildings concept. The buildings are usually designed applying transparent-material-covered walls to get the advantages of natural and artificial lighting combinations to optimize and save the consumed energy. This research proposes the use of a fuzzy logic method to control the artificial lighting in the airport passenger waiting room to obtain effective and efficient lighting energy consumption. Using LEDs as lighting devices, the lighting areas are divided into several rectangle zones to simplify the adjustment. For every zone, LEDs are divided into 4 groups, 2 groups are on the upper side and the others are on the lower side. Each group consists of 2 sets of light lamps and placed between the diagonal-adjacent sensors line. Light sensors are placed on each side of the zone to obtain the optimal control result. The LEDs group will be only affected by the two adjacent sensors that flank them diagonally. The result showed that the LEDs current supply controlled by fuzzy that applied to one zone can give sufficient illumination as the IATA's requirement which is between 200 - 300 lux on the floor level.
