摘要
作为户外照明产品的LED路灯,其可靠性必须进行现场的长程测试,而长程测试过程和方法对测量可信度会带来很大影响。本文针对LED的特性,讨论了LED路灯长程测试方法和测试过程中可能引入的误差以及改进的方法,包括被测光源特性、测试设备、测试环境等。
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.
