Abstract

A method of matching a color of a light to the color of an object is presented which results in custom colored light emitting diodes.

Claims (21)

1. A method comprising:

detecting a color of a material;

converting the color to an RGB/CMYK value; and

matching the color comprising;

mixing at least one population of a quantum dot into a matrix material; and

placing the mixture on a light emitting diode to convert a light output of the light emitting diode to a color matching the color of the material.

2. The method of claim 1 , wherein at least one of the mixing and placing of the mixture uses an automated process.

3. The method of claim 1 , further comprising converting the RGB/CMYK value to a CIE value.

4. The method of claim 1 , further comprising making a display of at least two light emitting diodes.

5. The method of claim 4 , wherein making a display utilizes a mapping software for a placement of the light emitting diodes.

6. The method of claim 1 , wherein the matrix material is selected from a group consisting of: thermally-curable matrix materials and ultraviolet (UV)-curable matrix materials.

7. The method of claim 1 , wherein the matrix material includes at least one matrix material selected from a group consisting of: urethane acrylate, polyacrylate, acrylated silicone, urethane acrylate epoxy mixture, and combinations thereof.

8. The method of claim 1 , wherein the matrix material includes a silicon matrix material.

9. A system comprising:

a system for detecting a color of a material;

a system for converting the color to an RGB/CMYK value; and

a system for matching the color comprising;

a device for mixing at least one population of a quantum dot into a matrix material; and

a device for placing the mixture on a light emitting diode to convert a light output of the light emitting diode to a color matching the color of the material.

10. The system of claim 9 , wherein the device for mixing includes an automated device.

11. The system of claim 9 , wherein the device for placing includes an automated device.
