Design and Implementation of Electronic Illumination Control System

Abstract

Power saving todays is the most important requirement, specially lighting where it consumes a sizable portion of total electric energy. Therefore, controlling the brightness of the light is necessary to save electrical energy. For achieving this, an electronic illumination control system is essential. This paper aims to design and implement a simple and low-cost illumination control system with high efficiency, based on some power semiconductor devices such as triode alternating current (TRIAC) and diode alternating current (DIAC). In this concern, the performance of the electronic illumination control system, as well, the electrical parameters (break over voltage, latching current, holding current, on-state voltage and off-state leakage current) of the proposed power devices were investigated, where it is proved that the achieved power saving of the present electronic illumination control system in the order of 27% was obtained- while retaining more than 90% of the original light intensity. Therefore, the proposed system can be applied to saving power in our daily lives.
