1、光控智能开关的设计及实现摘要随着社会的进步,人们越来越倾向节能、环保、智能。传统的照明灯,在一些场合,比如楼道、卫生间、小巷等,往往造成资源的浪费。用声光控开关代替住房楼道上的开关,天黑以后,当有人走过楼梯通道,发出脚步声或其它声音时,楼道灯会自动点亮,提供照明,当人们进入家门或走出公寓,楼道灯会自动熄灭。在白天,即使有声音,楼道灯也不会亮,可以达到节能的目的。声光控开关不仅适用于住宅区的楼道,而且也适用于工厂、办公楼、教学楼等公共场所,它具有体积小、外形美观、制作容易、工作可靠等优点,适合于各种楼房走廊的照明设备。降低能耗、节约能源、注重环保是当今世界的主潮流
2、,高能耗且会加剧温室效应的白炽灯越来越不受欢迎。声光控电路是声音和光控制电路工作的电子开关。它将声音(如脚步)和光转化为电信号,经放大、整形,输出一个开关信号去控制各种电器的工作,在自动控制工业电器和家用电器方面有着广泛的用途。由于,本电路广泛应用于人们的日常生活中,所以,有重要的现实作用。 关键词:光敏电阻,驻极体传声器,声光控,节能,电阻,电容20INTELLIGENTLIGHTCONTROLSWITCHDESIGNANDIMPLEMENTATIONABSTRACTAlongwiththeprogressofthesociety,peoplearemore
