中文介绍了所研制的基于积分球的光亮度标准，该装置的亮度示值误差小于１％，其相对光谱功率分布近于Ａ光源，０°～±５０°方向内光亮度偏差小于２．５％。
In this paper, the standard of integrating sphere based brightness is introduced in this paper. The device shows less than 1% brightness error, and its relative spectral power distribution is close to that of A light source. The deviation of brightness within 0 ° ~ ± 50 ° is less than 2.5 %.
