| Abstract: | As outdoor lighting products,on-site measurement of the whole LED street lights device is a very important for the evaluation of their reliability and other properties. While the long-term testing process and method have a great impact on measuring credibility. In this paper,we discussed various factors which may produce errors on the measurement of LED street light’ s photometric parameters and its on-site luminous degradation. These factors include the characteristics of LED,the measuring method and the measuring equipment etc. |
