IOT 區域化LED 控制系統

An Internet of Things (IOT)-Based Regionalized Intelligent Led-Light-Controlling System

近年來，減少住宅與工業用電一直是各國政府努力的目標，在總能耗中照明佔了很大一部分，不幸的是，這種能源被大量的浪費了。但由於大部分安裝的照明系統已過時且能源效率不佳，因此許多廠商將光控系統(Light Control Systems)引入當前市場，但由於成本高、安裝困難、維護不易，現有的光控系統並未成功應用於大樓、街道和工業建築。本研究提出了一種低成本、無線、易於安裝的智慧LED照明系統--IOT區域化LED控制系統，其最大的改進為可同時改變同一區域的LED燈亮度以節省能源，並可透過物聯網(IOT)的微控制器(Microcontrollers)和Internet來直接對LED燈進行參數設定，將所蒐集的資料上傳至雲端。以一般15W T8 LED燈管（非感應燈）為例，若將其替換為本智慧LED照明系統，且所裝設的地方是鮮少人經過的，則其省電率將高達90%，若是假設每小時有12人次經過，其省電率也還有81%，故其最大優點是既可保留原燈座、不需佈線、不用架設伺服器，便可達到智慧LED照明系統的節能目的。

Reducing residential and industrial electricity consumption has been agoal of governments around the world. Lighting sources account for alarge partition of the whole energy /power consumption. Unfortunately, most of the existing installed lighting systems are ancient and have poor energy efficiency. Today, many manufacturers have introduced light-controlling systems into the current market. However, existing light controlling systems may not be successfully applied to buildings, streets, and industrial buildings due to high costs and difficult installation and maintenance. To combat this issue, this article presents an easy-to-install, low-cost, master–slave intelligent LED light-controlling system based on Internet of Things (IOT) techniques. The benefit of using the proposed system is that the brightness of the LED lights in the same zone can be changed simultaneously to save energy consumption. Furthermore, the parameters of the LED lights can be directly set. Moreover, the related data are collected and uploaded to acloud platform. In this article, we use 15 WT8 LED tubes (non-induction lamps) as acase study. When the proposed system is installed in azone with few people, the power-saving rate is as high as 90%. Furthermore, when 12 people pass by azone within one hour, its power-saving rate can reach 81%. Therefore, the advantages of using the proposed system include: 1) the original lamp holder can be retained; 2) no wiring is required; 3) no server is set up. Moreover, the goal of energy saving can also be achieved.
