Patent ID: 7985000

Claim:
A method for making a lighting apparatus, the method comprising: for an LED die of a plurality of LED dice configured to emit a first color, determining a target amount of a wavelength-shifting material capable of converting light of the first color to light of a second color, wherein the target amount is an amount that, when combined with light from the LED die, will result in light of a third color; disposing the plurality of LED dice on a substrate to form a lighting apparatus; depositing less than the target amount of the wavelength-shifting material over each of a first subset of the plurality of LED dice; depositing more than the target amount of the wavelength-shifting material over each of a second subset of the plurality of LED dice; coupling the first subset of the plurality of LED dice and the second subset of the plurality of LED dice to a power controller; and using the power controller to adjust relative brightness of the first subset and the second subset of the plurality of LED dice such that the lighting apparatus is configured to produce light of the third color.
