Abstract
A method for determining a mixture composition of a plurality of fluorescent materials includes steps of calculating a first function, calculating a second function and determining a secondary mixture composition of the plurality of fluorescent materials. The first function is calculated by comparing an objective spectrum of an objective light with a reference spectrum of a reference light. The second function is calculated by comparing a primary spectrum of the plurality of fluorescent materials mixed at a primary mixture with the reference spectrum composition. The secondary mixture composition is determined on the basis of the result of comparison between the first function and the second function.
