光控照明电路的原理与设计

Design and principle on the light-controlled illumination circuit

对采用光敏电阻和照明控制继电器为基本元件组成的照明光控制电路进行了研究。这种照明光控制电路的特点是可以根据光线的亮度自动控制照明,与人工操作比较,开关及时,具有好的节能效果。介绍了其电路组成、工作原理和参数设计。

The illumination light-controlled circuit composed of the photoresistance and illumination-controlled relay as the pri- mary element has been studied. Its characteristic is controlling the illumination automatically according to the extent of the opti- cal fiber brightness. Compared with the manual control, it switches promptly and has a good energy-saving effect. The electri- cal circuit compositon, the work principle and the parameter design are introduced.
