Multizone mixing cup
A zoned 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 domed light converting appliance (DLCA) covering a cluster of LEDs providing a channel of light which is reflected upward by the cavities and mixed by angles walls and structures above the open top of the cavities in the common body of the cup.
1. A method of using a zoned light system to emit emitted light, the system comprising a unitary body comprising a first reflective cavity, a second reflective cavity, a third reflective cavity and a fourth reflective cavity; a first LED package situated in the first reflective cavity and adapted to emit light through a first luminophoric medium comprised of one or more luminescent materials and matrix in a first ratio; a second LED package situated in the second reflective cavity and adapted to emit light through a second luminophoric medium comprised of one or more luminescent materials and matrix in a second ratio; a third LED package situated in the third reflective cavity and adapted to emit light through third luminophoric medium comprised of one or more luminescent materials and matrix in a third ratio; a fourth LED package situated in the fourth reflective cavity adapted to emit light; said method comprising:
emitting a first combined light from the first LED package and through the first luminophopric medium, the first combined light being in a blue color range on 1931 CIE diagram;
emitting a second combined light from the second LED package and through the second luminophopric medium, the second combined light being in a red color range on 1931 CIE diagram;
emitting a third combined light from the third LED package and through the third luminophopric medium, the third combined light being in a yellow/green color range on 1931 CIE diagram;
emitting a fourth combined light from the fourth LED package, the fourth combined light being in a cyan color range on 1931 CIE diagram; and,
mixing the first, second, third, and fourth combined light together to form the emitted light.
2. The method of claim 1 , wherein each of first LED package, the second LED package and third LED package comprise at least one blue LED.
3. The method of claim 1 , wherein the fourth LED package comprises at least one cyan LED.
4. The method of claim 3 , wherein the fourth LED package comprises a fourth luminophoric medium comprised of one or more luminescent materials and matrix.
5. The method of claim 1 , wherein at least one of the first luminophoric medium, the second luminophoric medium and the third luminophoric medium comprises a plurality of quantum dots.
6. A zoned light mixing cup comprising:
a unitary body comprising a first reflective cavity, a second reflective cavity, a third reflective cavity and a fourth reflective cavity;
a first LED package situated in the first-reflective cavity and adapted to emit light through a first luminophoric medium comprised of one or more luminescent materials and matrix in a first ratio for a first combined light in a blue color range on 1931 CIE diagram, the first luminophoric medium positioned over the first LED package in a non-contact manner;
a second LED package situated in the second reflective cavity and adapted to emit light through a second luminophoric medium comprised of one or more luminescent materials and matrix in a second ratio for a second combined light in a red color range on 1931 CIE diagram, the second luminophoric medium positioned over the second LED package in a non-contact manner;
a third LED package situated in the second reflective cavity and adapted to emit light through third luminophoric medium comprised of one or more luminescent materials and matrix in a third ratio for a third combined light in a yellow/green color range on 1931 CIE diagram, the third luminophoric medium positioned over the third LED package in a non-contact manner;
a fourth LED package situated in the fourth reflective cavity adapted to emit light; and,
wherein the unitary body is adapted to combine the first, second, third, and fourth combined light together and wherein the fourth LED package comprises at least one cyan LED.
7. The mixing cup of claim 6 , wherein each of first LED package, the second LED package and third LED package comprise at least one blue LED.
8. The mixing cup of claim 6 , wherein the fourth LED package comprises a fourth luminophoric medium comprised of one or more luminescent materials and matrix in a fourth ratio.
9. The mixing cup of claim 6 , wherein at least one of the first luminophoric medium, the second luminophoric medium and the third luminophoric medium comprises a plurality of quantum dots.
