摘要: | 发光二极体被广泛用来制作照明设备,其特色是拥有较好的能源效能以及较长的生命周期。然而,发光二极体在超过特定温度区间后,亮度会下降以及减少生命周期。因此,如何使发光二极体在照明设备上维持高效能以及高省电将会是一项非常重要的议题。近年来,发光二极体的照明设备被广泛地利用在路灯以及室内照明。在室内照明的部分,应用于医疗的照明设备,除了须具备高效能和高省电外,还必须考量到使用在病人和护理人员上所带来的效果。本篇论文的主轴在于实作出应用于医疗以及室内用的照明设备,并且改善设备的效能使其更为省电,并搭配三种调控模式,使灯具可以更为适合医疗用的环境。为了达到此目的,我们透过微控制器调变模组调控发光二极体,并搭配环境光源感测器以及照度感测器去做亮度的回馈调整,并且搭上从此研究中所提出的控制方法,将使智慧照明设备可以自动随着环境变化去做自身的调控,达到发光二极体的高效能、高省电及智能化,以便在未来迎接一个医院物联网的时代。 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. |
