Intelligent Lighting System Design With Fuzzy Logic

This paper describes a design of an intelligent energy efficient lighting system based on fuzzy logic controller that uses white LEDs to produce light at the required luminance level in a typical room space. The lighting system incorporates automatic control of a room’s window shade opening, conveniently harvesting daylight. The study contains the simulation of the design in a MATLAB software environment using Fuzzy Logic Toolbox and Simulink blocks. The model test results demonstrate that the LEDs’ output average power automatically reduces as daylight entering the room increases. The designed lighting system intelligently optimizes on the high efficacy LEDs and the natural daylight in illuminating a room to required levels.Electrical energy for lighting the room is used only when the room is occupied and the artificial lighting is required.
