[Radiance-general] Modellling light pipes / light tubes

[Beeson, Brett]

Hi  all,

 

I'll like to model the effect of light pipes in a two storey building.
These pipes would enter through the roof via a half-dome of glass.  A
highly reflective pipe (approximately 400mm diameter) runs from this
roof to the ground floor's ceiling where it strikes a diffuser and
lights the space below.

 

The obvious way to model this would be a vertical cylinder with a highly
reflective surface inside.  Probably the top surface (where the light
comes in) should be an illum surface.  I'm not sure, however, that this
method would be very efficient or accurate.

 

What's the best way to model these light pipes?  Has anyone done a
similar thing?

 

Cheers,

 

Brett
