Abstract:
A method of disposing a phosphor material on an LED such that the LED emits white light and adjusting the quantity of phosphor material such that the white light meets a color target. A formulated procedure is used to determine the adjustment required, and includes a correlation between a change in position of a color of an LED on a CIE diagram and a known quantity of phosphor material added to the LED.
