BRIEF INTRODUCTION:
Today, energy conservation has become an important issue. The potential for energy saving is by using automatic dimming of electric lighting in order to take advantage of the daylight which was already investigated in the seventies.. Enough experimental data is available to indicate that energy savings associated with lighting can be made, by use of controls alternative to the wall-mounted switch panel. This project is to update the research in this field by presenting some new results of a methodology to design a mathematical model and a software simulator for the lighting system of a 2-zone room. The simulator is then used as a platform to develop the real-life microcontroller-based system to regulate the light amount in a room at a constant level, irrespective of the disturbances from outside. A LCS consists of three main elements: (i) a decision-making element (controller), (ii) sensors to supply light-level information to the controller, and (iii) switches or variable controls to the luminaries.
