應用於病房以及居家照護的智慧照明系統

Abstract

發光二極體被廣泛用來製作照明設備，其特色是擁有較好的能源效能以及較長的生命週期。然而，發光二極體在超過特定溫度區間後，亮度會下降以及減少生命週期。因此，如何使發光二極體在照明設備上維持高效能以及高省電將會是一項非常重要的議題。近年來，發光二極體的照明設備被廣泛地利用在路燈以及室內照明。在室內照明的部分，應用於醫療的照明設備，除了須具備高效能和高省電外，還必須考量到使用在病人和護理人員上所帶來的效果。本篇論文的主軸在於實作出應用於醫療以及室內用的照明設備，並且改善設備的效能使其更為省電，並搭配三種調控模式，使燈具可以更為適合醫療用的環境。為了達到此目的，我們透過微控制器調變模組調控發光二極體，並搭配環境光源感測器以及照度感測器去做亮度的回饋調整，並且搭上從此研究中所提出的控制方法，將使智慧照明設備可以自動隨著環境變化去做自身的調控，達到發光二極體的高效能、高省電及智能化，以便在未來迎接一個醫院物聯網的時代。

Light emitting diode (LED) has been widely used because of its energy-efficient illumination and long lifetime. High temperature induced by power density will decrease the lifetime and decrease illumination of LED. To improve power efficiency, a system-level approach is proposed in this work. In recent years, LED lighting devices are widely using in the street and indoor lighting. In indoor lighting, lighting used in medical not only has high efficiency and high energy saving, but also is considered the result which come from the patients and caregivers. This thesis focuses on using in medical and indoor lighting, and improves the efficiency and low power consumption. In addition, lighting with three control mode can make it more suitable for medical and indoor environment. To achieve this goal, we regulated LED through modulation microcontroller module, with ambient light sensor and the illuminance sensors do brightness adjustment feedback and combine the control method. It will make the lighting can automatically and achieve high efficiency, high power and more smart so as to usher an era of Internet of Thing.
