以太网供电（PoE）在照明中的应用

摘要

After introducing PoE standards including IEEE 802. 3af and IEEE 802. 3at and development of LED lighting technology, this paper discusses an emerging unique technological advantage that PoE application in conventional network equipment shifts to its application in lighting system, and puts forward the problems in subsequent use.%介绍以太网供电标准 IEEE 802.3af、IEEE 802.3at，结合LED照明技术的发展，阐述PoE供电由常规的应用于网络设备过渡到照明系统这一新兴技术独特的技术优势，提出需要在后续使用中注意的相关问题。
