一种简易光控照明电路的设计

随着光控电路的发展,光能在智能化设计电路中得到了广泛应用,本文设计了一种既实用又便于制作的光控照明电路,首先为确保电路能正常工作设计了一个稳压电路,然后利用光敏元件随光照强度的变化而阻抗发生变化的特点去控制电信号的强弱,再由传感器将变化的电信号传递给触发器,只要电信号强度达到一定程度就可触发触发器使其导通工作,这样就能实现当外界光照强度降低到一定程度时,使照明电路导通工作,从而就可实现光对照明电路的亮与暗的控制.

A Kind of Simple Design of the Light-Controlled Illumination Circuit

With the development of the light-controlled circuit,the energy of light has widely been applied in the intellectualization designed circuit.A kind of light-controlled illumination circuit which is both practical and conveniently made is designed in the article.At first,a voltage-stabilizer circuit is designed to guarantee the electrical circuit to work normally.Then the inpedance changes with the changing of the intensity of illumination,the light activated element uses this characteristic to control the s...
