I want to desing a optic guide for en LED.
It is possible to simulated this with povray?
I can not see where I can change specification of material to define the 
guide.
I am play with led source but not manage to make a led with 10degres angle.
Best regard
Thierry

Could you be more precise on what you want to achieve?
What is a LED optic guide?

I don't think that fibre optics (if that is what you mean) can be done in
Pov-Ray, not without faking it.

I might be wrong but using ior and rising the max_trace_level in the 
global settings should do the trick.
But only if the border angle where the refraction turns into reflection 
is used in POVRAY, which I don't know (yet).
It should be easy to write a test code ...

There is a test render at p.b.images
I think it works but don't ask me how good it is for real optics 
applications ...

To answer to Marc.
I am design a panel unit with 7 switch/ key. custormer will at when the key 
is activ, the key ligthing.
I have place 2 light source ( LED ) between the switch and want desing a 
knopp to active the switch and guide the light of LED to the top.
I will try differente form of knopp to have the best light on the top.

I have read the manuel with ligth source, try som but have not some result.
I am not a prof with povray, I am using Povray with the CAD software eagle 
to show som 3D pictures of my board.
I will try all tips you write.

I think you won't get accurate simulation of that guide.
Usually it is try and error process to get what we want.
But maybe you could try a pigment with filter 1
like :

pigment {color rgb 1 filter 1}

or shorter
pigment {color rgbf 1}

It is hard to give code without knowing exactly what you want :-)

ok thanks marc.
It is do not what I espect.
I understand at it is perhaps not povray SW to do this simulation.

Hi Thierry,

did have a look at

?

Is that what you want ...

Do you mean one of those clear plastic prisms that brings light from the LED
up to the front of a piece of consumer-electronics?  You might try enabling
photons and setting the optic guide as a "target."

http://www.povray.org/documentation/view/3.6.1/425/

Also see the insert-menu item "Photons scene" under "scene templates" (if
you're using Windows)for a good demonstrations of using photons.

I haven't tried it, but I have a feeling you may also need a
double-illuminated surface for the photons to hit after going through the
prism.  Again, I'm not sure if this is what you are looking for, and I
haven't tried what I am suggesting.

Charles
