Abstract：With the widely application of LED in city, complains from light pollution incidents had gradually increased, and there still had no quantitative monitoring and evaluating of it.For these reasons, the studies of monitoring light pollution of LED need to be established urgently.Six representative regions of LED in Shenyang were chose to be monitored.By measuring the light pollution of LED screen, the main factors affecting the night light pollution were analyzed.The results showed that, distance, ambient lighting, angle, LED screen area and illumination had direct impact on light pollution of LED.Based on monitoring and analyzing, evaluation system of LED ’ s light pollution was established.The light pollution was ranked according to human senses into 5 scales:More serious, serious, general, mild, no effect.At last, the extent and scope of LED’s light pollution in Shenyang residential areas were defined.It can provide a theoretical basis for quantitative evaluation of LED light pollution, as well as beneficial to the establishment of relevant laws and regulations.
