Abstract: An approach is described for manufacturing wavelength conversion components for lighting devices which employ in-line process controls to minimize the amount of perceptible variation in the amount of photo-luminescent material that is deposited in the wavelength conversion components. Weight measurements are utilized in the manufacturing process to control and minimize the amount of the variations. In this approach, the weight of the product during manufacturing is used as a surrogate to a measure of the amount of photo-luminescent material in the component, and hence a surrogate for the expected color properties of the manufactured product. By measuring and checking for weight variations for the component, one can quickly determine with reasonable confidence whether there are any variations in the amount of photo-luminescent in the component.
