单项选择题

阅读下面的现代文，完成第7～10题。
走进北京科技大学，谈起新建的学校体育馆，人们总是把体育馆内采用的光导照明系统作为科技奥运理念的一大亮点向你介绍。
光导照明系统由采光装置、导光装置、漫射装置组成，它通过采光罩高效采集自然光线导入系统内重新分配，再经过特殊制作的光导管传输和强化后，由系统底部的漫射装置把自然光均匀高效地照射到任何需要光线的地方，得到由自然光带来的特殊照明效果。从黎明到黄昏，哪怕是雨天和阴天，光导照明系统导入室内的光线依然很充足，每天至少可提供十小时的自然光照明，从而打破了场馆室内必须依靠电力照明的传统观念。是一种只需一次性投资，无需维护的节能、环保、安全健康和时尚的新型照明装置。
新建的北京科技大学体育馆共安装了148个直径为550mm的折射率为99.7%光导管，是目前所有奥运场馆中在比赛场地中央唯一安置光导照明系统的。经实测，在室外临界照度值为20000Lx时指定场地地面的室内临界照度能达到150Lx，采光均匀度≥0.7。白天，它采集的光线能满足体育训练的要求。晚上，则可以将室内的灯光通过屋顶的采光罩传出，起到美化夜景的效果。此外，当场馆不需要光线时，还可通过该系统中唯一使用电力的配套设备电动日光调节器，任意调节光线的明暗，以保证奥运比赛时龟视转播的需求。

下列有关光导照明系统的说法，不正确的一项是( )

A．光导照明系统分别由采光装置、导光装置、漫射装置组成。

B．采光装置可以高效采集自然光线导入光导照明系统内对自然光线进行重新分配。

C．导光装置将采光装置采集的自然光线用光导管进行特殊的传输和强化。

D．漫射装置可以将自然光投射到体育馆的任何地方。
