A lighting designer is using a lighting measurement tool to determine if the external lighting for a project is compliant with Light Pollution Reduction. Which of the following would be considered compliant?
照明设计师想确认室外照明是否可以符合降低光污染的要求，以下哪项需要被考虑
A: 照明灯具开启时的照度不比关闭时照度高20%
B: 照明灯具平均照度不超过2500流明
C: 在场地边界照度低20%
D: 照明灯具开启时的照度不比关闭时照度高500流明

参考答案: A

本题解释:
选择A，本题解释Once the measurements have been taken, compare the illumination measurements with lights off versus the lights on at each measurement point along the boundary. The illumination with the lights on must be no more than 20% above the level of the illumination with the lights off. This requirement must be met at all measurement points. You cannot take an average across the project boundary.
