Simulation of Dimmer Circuit for Daylight Harvesting

AbstractIn this paper a fuzzy based dimmer circuit model for daylight harvesting is proposed. The model incorporates the variable daylight intensity and number of occupants in a room. The dimmer circuit controls the switching ON and OFF of LEDs (light emitting diode) in a room corresponding the daylight intensity and occupants while the required level of illumination is maintained. The uncertainty in input variables is incorporated in the model with the fuzzy logic. The developed model is simulated in MATLAB and LABVIEW environment. The developed model is tested for different situations
