Dynamic Dimming Control Method Research on Tunnel LED Lighting Based on LED Controllability

By combining theoretical analysis and practical test, this paper present an dynamic dimming control method of highway tunnel LED lighting based on controllability of LED light, and undertook a comprehensive analysis of dynamic control method and Principle. And developed a highway tunnel LED lighting dynamic dimming control system. Through the demonstration analysis on tunnel LED lighting system of demonstration project, it indicated that the research results can significantly save the lighting electricity cost of highway tunnel lighting system under safety, on-demand lighting conditions. Which will provide a energy saving dynamic dimming control scheme for highway tunnel LED lighting system in our country.
