摘　　要：进入21世纪以来,我国的城市建设取得了飞速的发展。作为一个城市地标的商务区,其照明备受关注。LED显示屏已经成为了城市商务区商业照明不可或缺的一部分,由于大屏幕显示屏的使用时间和使用范围的扩大,环境问题也逐渐暴露出来,如亮度过高所带来的能源浪费、眩光和光污染问题等。本文将通过对徐家汇商业区LED显示屏三年来的研究结果的分析,从亮度和亮度对比度的角度思考LED显示屏的合理使用。In 21 century,China 's urban construction has achieved rapid development. Urban business district( UBD),is a city 's landmark,thus its nightscape lighting attracts much attention. LED display panels have became a integral part of UBD,but the environmental issues have exposed with the widespread use of large- screen display,such as brightness causes excessive energy waste,glare and light pollution and so on. This paper compares three years' research luminance data on XuJiahui's UBD,and discusses brightness and brightness contrast from the perspective of the rational use of the LED display.

关 键 词：城市商务区 LED显示屏 亮度 亮度对比度 光污染
