Patent ID: 8087798

Claim:
A method of selecting individual lighting elements to be used in an array of lighting elements, comprising: selecting a parameter of the array of lighting elements to optimize; testing the individual lighting elements in a production batch available for a manufacture of the array of lighting elements to characterize a performance of the individual lighting elements for the selected parameter by a performance distribution curve for the selected parameter; establishing two or more sub-ranges for the performance of the individual lighting elements for the selected parameter, each sub-range being a subset of the performance distribution curve for the selected parameter; associating each of the individual lighting elements with one of said sub-ranges based on the performance of each individual lighting element for the selected parameter; and matching an individual lighting element from a first of said sub-ranges based on its performance for the selected parameter with a lighting element from a second of said sub-ranges based on its performance for the selected parameter, wherein the first of said sub-ranges is a first subset of the performance distribution curve for the selected parameter and the second of said sub-ranges is a second subset of the performance distribution curve for the selected parameter, and the second subset is substantially non-overlapping with the first subset; and manufacturing a light from the array of lighting elements using the matched individual lighting elements.
