“…Finally, for time constant values above (19 ms), the signal is completely diminished (Fig. 9e) due to the fact that the capacitor will never reach DIAC breakover voltage [22,23]. Figure (10) shows the dependence of voltage, current , power and power factor of the system output on firing angle.…”

“…Figure (10) shows the dependence of voltage, current , power and power factor of the system output on firing angle. For the four paramaters, their values are shown to be a function of the firing angle values [23]. -81-Figure (11) presents the effect of firing angle on the intensity of illumination, percent of power consumption (ρ%) and power saving ratio (δ %).…”

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.
