基于Android的智能可调光LED灯节能控制

摘要

In order to solve the problem of energy consumption of household LED lamps, an energy-saving control method using an intelligent dimmer is proposed. The method takes the Android operating system as a platform, an intelli-gent mobile phone as a client, and uses the Buck LM3409HV adaptive feedback control mechanism to realize the remote wireless adjustable light energy-saving of LED lights, and low power lighting control through a WiFi net-work. The system constructed with the method uses the renewable green solar energy to supply smart grids, and ad-justs the brightness of LED lights through the photosensitive sensor and pulse width modulation ( PWM) technology and the combination of the outdoor light intensity. Running in the universal input voltage, the system can achieve the high efficiency, high power factor dimming. Compared with traditional mechanical switch LED lighting lamps, this intelligent dimming system’ s design of hardware and software is more flexible and convenient, with the lower cost, less power consumption, as well as the general, accurate interface and functions. It has the wide application prospect.%针对家庭LED灯能源耗电问题，提出了一种智能调光节能控制方法。该方法以安卓操作系统为平台，智能手机作为客户端，利用LM3409 HV降压自适应反馈控制机制，通过WiFi网络实现无线远程可调光节能LED灯的低功率照明。该系统采用太阳能绿色可再生能源为智能电网供电，结合室外光强，通过光敏传感器和脉宽调制( PWM )技术调节LED灯亮度。在通用输入电压下，可实现高效率、高功率因数调光。与传统的机械式开关LED照明电灯相比，智能调光系统设计的软硬件更为灵活和方便、成本更低、功耗更小，界面和功能都具有良好的通用性、准确性，具有广泛的应用前景。
