Abstract
An optical cup which mixes multiple channels of light to form a blended output, the device having discreet zones or channels including a plurality of reflective cavities each having a remote light converting appliance covering a cluster of LEDs providing a channel of light which is reflected upward. The predetermined blends of luminescence materials provide a predetermined range of illumination wavelengths in the output. The remote light converting appliances may be provided as frustoconical elements directly adjacent to the LEDs within frustoconical reflective cavities. An index matching compound can be disposed between the light converting appliances and the associated LEDs.
