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.
