高速公路可变情报板LED单灯组合方案的设计与工程应用

Design and Engineering Practice of LED Combinations Used in Changeable Message Sign of Expressway

本文从工程实践角度出发 ,结合高速公路监控系统中可变情报板用LED技术的最新进展 ,探讨了原“5红 3绿”LED单灯组合设计方案的历史背景与当前应用中的问题 ,提出了“5红 2绿”和“5红 2绿 1蓝”等新单灯组合配比方案 ,较好地满足了技术先进与造价合理的平衡性要求 ,该改进方案已在连霍国道主干线 (江苏省连徐段 )高速公路机电工程中成功应用 。

Based on the up-to-date development of LED engineering application and practice,this paper discusses the background and limitation of“5R+3G”design scheme,and brings forward some new combinations,such as“5R+2G”and“5R+2G+1B”,which meet the balance requirements of advanced technique and reasonable cost as well The innovative design mentioned in this paper has been successfully applied to Lianxu Expressway in Jiangsu Province,the section of Lianhuo National Trunk Highway The Jiangsu Expressway Construction Headquarters also adopted the design in the bidding documents for other expressways
