An Improvement of Led Lighting System Accuracy with Voltage Control System

This paper proposes an effective LED lighting control system to increase the accuracy of electric power usage. The efficient use of electric power is a problem that needs to be pursued a solution. There are several previous works have been proposed to reduce electric power consumption. However, no one has focused on saving LED lights by using a voltage control system. In this paper, a LED lighting control system has been developed by adjusting environmental conditions using light intensity sensors and the presence of people. Some experiments have been carried out to prove the effectiveness of the system. The results show that the system has successfully adjusted the light intensity based on the presence of people in the room and room light intensity. So, the light intensity could adapt to the environment as the control system work. PWM control system has a high correlation, more than 99%, compare to room light intensity. It shows the effectiveness of the control system. Thus the goal of lighting efficiency has been achieved effectively.
