摘　　要：目前,无线开关通常采用电池供电,针对该类开关存在频繁更换电池的弊端,提出了一种基于弱光充电的低功耗无线触摸开关。系统采用弱光型太阳能电池。该电池模块在室内光的情况下即可实现对电容充电。由于电容的电压高于电池电压,因此白天情况下,整个无线发射系统由电容供电,大大增加了电池的待机时间。经实际测试,本系统较好地解决了无线开关频繁更换电池的弊端。At present,wireless switches are usually powered by batteries. In view of the drawbacks of frequent battery changes in such switches,a low-power wireless touch switch based on low-light charging is proposed. The system USES a low-light solar cell,which can charge the capacitor in indoor light. Since the capacitor voltage is higher than the battery voltage,the whole wireless transmission system is powered by the capacitor during the day,which greatly increases the battery standby time. Through the actual test,this system has solved the malpractice of changing the battery frequently.
