A system and method is disclosed for determining the proper mixture of
substances (e.g. phosphors) or sources (e.g. of light) to obtain a
required or desired property, such as color or chromaticity. Steps may
include mixing the substances or sources, preparing a prototype, measuring
the property (such as chromaticity) of the prototype, and calculating any
required adjustment in the quantities of substances or sources. This
process may be repeated until the desired property is achieved, after
which the mix of substances or sources may be used to manufacture
products. A computer spreadsheet is also disclosed, as an exemplary
embodiment, which calculates any required adjustments in the quantities of
substances or sources. The spreadsheet provided is specifically configured
to calculate adjustments in phosphor quantities required for manufacturing
lamps for backlighting in AMLCD avionics applications.
