公路隧道蓄能发光材料辅助照明技术全寿命周期成本对比分析

Comparative analysis of life cycle cost for energy-storing luminescent material auxiliary lighting technology in highway tunnels

“双碳”政策对公路隧道的建设运营提出了更加低碳、节能、环保的要求,利用蓄能发光多功能材料辅助隧道照明是公路隧道照明节能发展的新方向。基于隧道全寿命周期理念,从建设、运营阶段的成本方面对蓄能发光材料辅助照明方案和常规LED灯照明方案进行了分析,并结合工程实例对两种方案的全寿命周期成本进行了对比。结果表明,蓄能发光材料辅助照明方案更为安全舒适、绿色低碳,虽然建设成本略有增加,但因节能效果显著而使运营成本大幅减少,全寿命周期成本更低,更有利于“碳达峰”“碳中和”目标的实现。研究结果可为建设单位、管理单位、设计单位等在选择公路隧道照明方案时提供参考。

The“carbon peaking and carbon neutrality”policy puts forward more low-carbon,energy-saving and environmental protecting requirements for the construction and operation of highway tunnels.Using multifunctional energy-storing luminescent material to assist lighting is a new direction for the energy-saving development in highway tunnels.Based on the concept of tunnel life cycle,the costs of energy-storing luminescent material auxiliary lighting scheme and conventional LED lighting scheme in construction and operation stage are analyzed,and the life cycle costs of two schemes are compared with engineering examples.The results show that the auxiliary lighting scheme is safer,more comfortable,green and low carbon.Although the construction cost increases slightly,the operating cost is greatly reduced due to the significant energy-saving effect,and the life cycle cost is lower,which is more conducive to the realization of the carbon peaking and carbon neutrality goals.The research results can provide reference for construction units,management units and design units in choosing highway tunnel lighting schemes.
