Research of Highway Tunnel Lighting System and Control Methods Based on the PV-LED

摘要:

针对阳光输送机的可靠性差等问题,设计了一种具有自动组合功能的PV-LED隧道直接照明系统及控制方法；该系统充分利用了阴雨天散射的太阳光,使增强照明部分可根据隧道外太阳光强弱自动变化,有效回避了阳光输送机本身存在的因为天气阴、晴变化导致太阳光时有时无工作稳定性差的先天性缺陷；从理论和实践结合的基础上实现了隧道的基本照明和增强照明系统,为太阳能推广应用开辟了一条新道路。

Abstract:

In view of the poor reliability of sunshine conveyor problem, we design a combined function with automatic features of PV - LED tunnel direct lighting system and control method. The system makes full use of the scattering of sunlight rainy days, so that the enhanced lighting parts change automatically according to the intensity of sunlight outside the tunnel .This system effectively avoid the sunshine conveyor itself exists because of the weather overcast or sunny changes in the sun and sometimes lead to poor working stability in congenital defect. To achieve the basic lighting and tunnel lighting system enhancements from the basic theory and practice on the promotion and application of solar energy has opened up a new path. 
