Hi there, I'm new to POV-Ray and am trying to model some Luxeon emitters.
I'd like to model the radiation patterns they produce. The technical
documents give some typical spatial radiation patterns :

I was hoping I could enter this information into the settings for a light
source somehow, but can't see a way to go about it. Could anyone suggest a
way to achieve this?

My best guess would be to somehow use either emitting media w/radiosity, 
or a small area light with the appropriate areas shadowed.

One thing my may be interested in, becuase you can define light by 
wavelength and color temp:
