In this paper, the field detection method of LED road light decay is studied.
Based on the principle of relative droop, research is a kind of conform to the LED street light and other LED lighting lamps and lanterns of the droop test method, and corresponding test equipment development, solve the current lab droop life testing of lamps and lanterns are widespread and bigger difference of the actual application environment, the test time is too long and complex process, high cost and not easy to monitor droop lead to problems such as failure point in time, for improving the quality of LED lighting products as a whole and promote the healthy development of the LED industry has very important significance.
