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 phosphor light converting appliance covering a cluster of LEDs providing a channel of light which is reflected upward. The predetermined blends of phosphors provide a predetermined range of illumination wavelengths in the output.
Claims15
A method of blending multiple light channels to produce a preselected illumination spectrum, the method comprising:
- providing a common housing with an open top and openings at the bottom, each bottom opening placed over an LED illumination source;
- placing a domed lumo converting appliance (DLCA) over the each bottom opening and over each LED illumination source;
- altering the illumination produced by a first LED illumination source by passing it through a first domed lumo converting appliance (DLCA) associated with the common housing to produce a blue channel preselected spectral output;
- altering the illumination produced by a second LED illumination source by passing it through a second DLCA associated with the common housing to produce a red channel preselected spectral output;
- altering the illumination produced by a third LED illumination source by passing it through a third DLCA associated with the common housing to produce a yellow/green channel preselected spectral output;
- altering the illumination produced by a fourth LED illumination source by passing it through a fourth DLCA associated with the common housing to produce a cyan channel preselected spectral output;
- blending the blue, red, yellow/green, and cyan spectral outputs as they exit the common housing;
- wherein the first, second, and third LED illumination sources are blue LEDs and the fourth LED illumination is cyan LEDs;
- wherein the blue LEDs have a substantially 440-475 nms output and the cyan LEDs have a substantially 490-515 nms output;
- and,
- wherein each DLCA provides at least one of Phosphors A-F.
A method of blending multiple light channels to produce a preselected illumination spectrum, the method comprising:
- providing a common housing having an open top, a plurality of reflective cavities with open bottoms, and each cavity having an open top, each open bottom placed over an LED illumination source;
- placing a lumo converting device over each cavity's open top;
- altering the illumination produced by a first LED illumination source by passing it through a first lumo converting appliance (LCA) to produce a blue channel preselected spectral output;
- altering the illumination produced by a second LED illumination source by passing it through a second LCA to produce a red channel preselected spectral output;
- altering the illumination produced by a third LED illumination source by passing it through a third LCA to produce a yellow/green channel preselected spectral output;
- altering the illumination produced by a fourth LED illumination source by passing it through a fourth LCA to produce a cyan channel preselected spectral output;
- blending the blue, red, yellow/green and cyan spectral outputs as they exit the common housing;
- wherein the first, second, and third LED illumination sources are blue LEDs and the fourth LED illumination is cyan LEDs;
- wherein the blue LEDs have a substantially 440-475 nms output and the cyan LEDs have a substantially 490-515 nms output;
- and,
- wherein each LCA provides at least one of Phosphors A-F.
