The Research of LED Street Lamp Illuminance Maintenance rate Testing in The Outdoor Environment
Li Benliang
Abstract：With the popularization and application of LED street lamp , the lighting output descent of lamp was paid close attention to by its users .The author of this paper installed two batch of LED street lamps in the outdoor, carried out illumination maintenance rate tracking test , analyzed LED street lamp lighting output descent and fault conditions .Test results showed that the first batch of LED street lamp installed in 2010 has descended greatly and the product failure rate is high ; whereas, the overall descent rate is relatively small and the overall product failure rate is low for the second batch of LED streetlights installed in 2012.The comparison of test results showed that with improvement and upgrading of LED street lamp technology for the past two years, the attenuation problem obtained a better solution , life performance of products has been greatly improved , and the failure rate descended slightly .
