摘　　要：国家和社会对资源节约和环境保护提出了新的要求,发光二极管(LED)照明作为新兴节能光源逐渐应用到路灯上,并以其优良的性能和广阔的发展前景渐渐体现出取代被誉为第三代路灯照明光源——高压钠灯的趋势。因此,发光二极管道路照明技术的研究对照明节能设计具有重要的现实意义,本文将结合CAT4101芯片特点和应用实际对发光二极管道路照明电路设计及相关特性进行浅析。The state and society and resource conservation and environmental protection requirements, the light-emitting diode （LED） lighting as an emerging energy-saving light source is gradually applied to the street lights, and its excellent performance and broad prospects for development gradually reflects replaced by reputationthe third generation of street lighting - the trend of high-pressure sodium lamp. Therefore, the study of light-emitting diode road lighting technology, lighting, energy efficient design has important practical significance, this paper will combine the CAT4101 chip characteristics and the actual light-emitting diode road lighting circuit design and related features analysis.
