Method for controlling color accuracy in a light-emitting semiconductor-based device and process for producing a light-emitting semiconductor-based device with controlled color accuracy

Abstract

A method for controlling color accuracy of a light-emitting semiconductor-based device, and a process for producing a light-emitting semiconductor-based device with desired color accuracy is disclosed. The color accuracy is controlled by defining a desired color accuracy of a light produced by mixing colors emitted by at least two light sources over a first range of operating conditions; determining characteristics of the light as a function of operating conditions; and establishing desired light characteristics of the at least two light sources over a second range of operating condition in accordance with the step of defining and the step of determining.
