Abstract

Provides the methods of measurement for light source colour for general lighting service by the XYZ colorimetric system based on 2-degree field of view (hereafter referred to as XYZ colorimetric system), and the X[10]Y[10]Z[10] colorimetric system based on 10-degree field of view (hereafter referred to as X[10]Y[10]Z[10] colorimetric systems).
