Paul,

It's a non-imaging concentrator. The "compound parabolic concentrator" form
(cone like) is supposed to give performance that approaches the theoretical
(thermodynamic) limit.

The most prolific author in the field may be Roland Winston. The research
field was pretty active 30 years ago. I expect that it's more of a niche
field now, but there are enough real applications that it's not dead.

Thank you. Given the name of the design, I was able to find an easy to
understand explanation:

I have pursued this further downthread.
