摘 要
本课题介绍的光控自动照明灯，电路简单，实用方便。通过光控照明电路，以达到节省能源的目的，该设计主要介绍的是光控的电路设计。光控是通过光敏电阻来实现的，当光敏电阻在有光的时候灯就会慢慢的熄灭。在较黑暗或完全没有光照的时候，灯就会亮起来，这样就达到了节电和节能的目的，延长了灯的寿命。在实际生活中节电节能能够实现更多的自动化。
在现代社会中，某些场所灯光已经不再满足于单纯的手动开关，而是向智能化和人性化方向发展，方便与节能已经是主题口号，所以各种光控灯应运而生，而且在光控基础上在发展成为更实用的声光控照明灯，所以研究光控的原理是非常有必要的。
整个电路由光敏电阻、发光二极管、运算放大器、若干电阻和电源构成。电源提供电压，光敏电阻对外界光进行测量，运算放大器对压差进行比较。从而实现有光时，发光二极管不亮；无光时，发光二极管自动点亮，光敏电阻在测试光照的情况下改变电阻，通过运算器为二极管提供电压，实现二极管发光的自动控制.
