3 Terms and Definitions
GB/T 5698 and established the following terms and definitions apply to this standard.
3.1
CIE defined by the incident on the object of a specific relative spectral power distribution. Including CIE standard illuminant A and the CIE standard
Quasi illuminant D65.
3.2
In the three-color system, and the amount of test color stimuli color stimuli reach three reference color matching required. In CIE1931 standard colorimetric system
In with X, Y, Z represent the tristimulus values; in CIE1964 standard colorimetric system with X10, Y10, Z10 represents tristimulus values.
3.3
Tristimulus values with each of them and the ratio.
In CIE1931 standard colorimetric system by the tristimulus values X, Y, Z coordinates to calculate outstanding x, y, z;
In CIE1964 standard colorimetric system by the tristimulus values X10, Y10, Z10 calculate outstanding coordinates x0 10, y 10, z 10.
3.4
Matching energy spectrum of each wavelength required reference color stimuli [X], [Y], [Z] (or [X10], [Y10], [Z10]) of a single set of normalized
Color radiation tristimulus values.
CIE1931 standard colorimetric system color matching function () lambda, y () lambda, z () lambda represented by x0;
CIE1964 standard colorimetric system with color matching functions x0 10 () lambda, y 10 () lambda, z 10 () lambda represents.
3.5
The color of the light emitted by the light source.
