随着照明系统智能化及LED照明技术的迅猛发展，传统的路灯照明交流供电系统在可靠性、效率、控制灵活性的不足日益显现。文章聚焦直流供电技术在路灯照明系统中的应用，探究了路灯照明直流供电系统的优势，设计了采用直流供电的路灯照明系统构架，且借助具体的工程实例对其可行性进行验证。与传统交流系统对比，直流供电系统展现出更高的能源效率和更好的系统兼容性，可有效削减运行成本，提升运行可靠性。

With the rapid development of intelligent lighting systems and LED lighting technology, the limitations of traditional AC power supply systems for streetlight—in terms of reliability, efficiency, and control flexibility are becoming increasingly apparent. This study focuses on the application of DC power supply technology for road lighting. It explores the advantages of DC power supply technology, designs a DC-based road lighting system architecture, and validates its feasibility through a practical engineering case. Compared with traditional AC systems, this particular DC power supply system demonstrates more higher energy efficiency, and better system compatibility. Thus it can effectively reduce operational costs and enhance operational reliability.
