Last year I suggested to one of the Lumileds engineers that they use this to build multi-layer white output LEDs. The idea is to do without the 30% loss of output that results from using phosphor. They could also free themselves from all the other phosphor tyrannies.
By stacking the layers, the beam is more uniform.
The parts would be laser trimmed and then use active feedback to maintain their tint integrity over their lifetime.
He seemed interested and asked for the foveon website.
But I really think he thought I was nuts...
