directional diffuser
I have fitted a rigid sunpipe (300mm) in the roof of my extension to
brighten a dark corner, which it is doing, but the diffuser that fits on the end of the tube is multi-directional - as you'd expect from a diffuser. The diffuser is polycarbonate with random angled facets to spread the light in all directions. Now, a diffuser is needed to protect the eyes when the sun is reflected directly in the tube (and to seal the bottom of the tube), but I'd like something that sends all the light in one broad direction, i.e. towards a 45 degree sector of the sphere, so no light is being sent back towards the windows and being "wasted". Anyone come across such a thing, such as on some fancy light fitting ? I could seal the end of the tube and have some mirror type arrangement below, but that would be inefficient and look ugly. Cheers, Simon. |
