用管子来代替平板使的从不同的方向捕捉阳光(包括漫射光)—即使是从屋顶反射过来的光，成为可能。

Using tubes instead of flat panels makes it possible to capture sunlight, including diffuse light, from any direction-even if it is reflected up from a roof.

漫射光色反射从一个方向来的光，因此对于径直照射的表面来说就比仅是光线斜射过的表面更为明亮。

Diffuse color reflects light that comes from one direction, so it's brighter if it comes squarely down on a surface that if it barely glances off the surface.

为了达到这个要求，在这些房间里面设计了可以向北打开的天窗，允许漫射光进入室内，而不打扰或影响日常工作。

In order to achieve this objective, North-oriented skylights have been opened in these rooms, allowing the entrance of diffuse light without bothering or interfering with the daily work.
