住宅小区路灯线路光时控制器设计

Design of Light-Time Controller for Residential District Road Lighting Line

根据城镇住宅小区路灯照明的特点,设计了一种新颖的路灯线路光时控制器。光控电路由CMOS同相缓冲器组成的施密特触发器以及光敏电阻等元件组成,时控电路采用CMOS同相缓冲器组成的电容充电式延时电路。对电路组成、工作原理、参数设计进行了介绍,并通过电路仿真证明了其可行性。该控制器电路简单,实用性强,成本低,使用方便,实际使用效果良好。

According to the characteristic of residential district road illumination, a kind of novel road line light-time controller was designed. The light controlling electric circuit was composed of the Schmitt trigger which was composed of the CMOS synchronism buffer and the light/electricity converts electric circuit. The time controlling electric circuit was made up of capacitor charge delay electric circuit. The electric circuit composition, the work principle and the parameter design were introduced. The feasibility was proved through the circuit simulation. The controller had simple electric circuit, good practicability, low cost, easy operation and good effect.
