Abstract
Most installed lighting systems are outdated and have poor energy efficiency. Therefore, there is an urgent need for smart LED lighting systems that are energy efficient, easy to install, and inexpensive. In this article, a leader-follower smart office lighting control system based on Internet of Things (IoT) technology is proposed to satisfy the goal of saving energy through the coordinated operation of a system counter and an infrared (IR) human movement sensor (passive infrared (PIR) sensor). When no one is present in the space, all indoor LED lights are turned to low-light mode. Otherwise, all indoor LED lights are turned to high-light mode together. In addition to change the brightness of LED lights in the same area at the same time to save energy, the parameters of the LED lights can be set directly through microcontrollers via the IoT and the internet. If a general 15 W T8 LED tube (noninduction light) is replaced with the proposed leader-follower office lighting system (assuming that the office is occupied for 10 hours a day and that the hourly low-light mode is 20 minutes), then the power-saving rate is as high as 28.13%.
Highlights
The respondent thinks that this office lighting system can operate in low-light mode when there is no one in the office space and does not allow the office space to become totally dark during working hours
The Internet of Things (IoT). 5) If a general 15 W T8 LED tube is replaced with the proposed office lighting system, the power-saving rate is as high as 28.13%
This article proposes an energy-saving, easy-to-install, wireless, low-cost IoT-based leader-follower smart office lighting control system that is very suitable for installation in the office of a large company or factory
Summary
The rapid industrial and economic development of various countries has irreparably damaged the Earth’s environment. Research has found that simple lighting control using motion sensors can effectively reduce energy consumption in buildings. This article proposes a low-cost, easy-to-renovate intelligent lighting control system suitable for office environments that can retain the original lamp holders without the need for wiring, server setup, and leading to energy savings. RELATED WORK LED lighting is environmentally friendly but is still not popular, mainly because its installation cost remains higher than that of existing lighting devices. The lighting field’s energy efficiency and control research results have been fruitful, and the various technologies and solutions that have been proposed [14]-[29] can mainly be divided into two methods: wired and wireless systems. Combining advanced WSN control with DC-powered LED lighting systems should achieve greater energy savings in green smart buildings [16]. Depending on the surrounding environment of the streetlight, the brightness of the LED is adjusted
