Abstract

Reliability of high-power LED streetlight is researched in this paper. A accelerated life test is carried out to acquire the lifetime prediction of high-power LED streetlight and drive-power analysis. The test shows that reliability of high-power LED streetlight is much influenced by junction temperature of LED lamp and drive-power of the streetlight. Some suggestions on improving the design of streetlight will be given according to the research. It can be operated remotely from another station connected to the server via the World Wide Web.

大功率LED路灯可靠性分析
本文对大功率LED路灯的可靠性进行了研究。为了获得大功率LED路灯的寿命预测和驱动功率分析,进行了加速寿命试验。试验表明,大功率LED路灯的可靠性受LED灯的结温和路灯的驱动功率的影响较大。根据研究结果,提出了改进路灯设计的建议。它可以从另一个站通过万维网连接到服务器远程操作。
