摘要
LED路灯作为道路照明的发展趋势已经得到普遍认同,但产品研发过程中却忽略了在寒地应用环境下的特殊技术要求。文章讨论了冷热冲击的温度变化可能引起LED器件的失效问题和LED驱动装置低温运行的可靠性保障,并依据大量实验和应用数据,总结了LED道路照明装置在低温运行环境推广应用的特殊技术要求和设计指导意见,并提供了详细的指导性规范准则。
LED street lamp used for roadway lighting is commonly recognized,but the technical requirements of application in cold area are neglected in product research.This paper discusses the devices failure of LED caused by the temperature change due to hot and cold impact and the reliability guarantee of the cold operation of LED driving devices.Meanwhile,the special technical requirements for cold operation of LED roadway lighting devices were summarized and guides for LED design were also given.This study provides the detailed guidance standards for cold application of LED roadway lighting.
