Real-Time Control Algorithm of Intelligent Energy-Saving Lights based on IoT

Abstract

The world is currently facing a very serious energy crisis, how to save energy and improve energy utilization is an important issue to all countries. Lighting power consumption occupies a large proportion of people's electricity consumption, and most of the existing lighting control strategies are based on the activities of people or time scenes, ignoring the influence of natural light. In this paper, in order to make full use of natural light, we propose a real-time control algorithm of intelligent energy-saving lights. When natural light exists, the strategy calculates the level of light brightness at that moment through an algorithm and adjusts the brightness level of luminaire. This method saves energy by reducing the luminaire brightness level while meeting people's needs for work surface illumination. The simulation results indicated that our real-time lighting control algorithm has better energy saving effect compared with the traditional lighting control strategy.
