Definition

Daylight simulator is a “device that provides spectral irradiance approximating that of a CIE standard daylight illuminant or CIE daylight illuminant, for visual appraisal or measurement of colours” [1].

Development of the CIE Methods of Assessing Daylight Simulators

Although for decades after the acceptance of the CIE system (1931), Illuminant C was accepted and widely used in colorimetry, the practical implementation of Source C was limited to special laboratory use. In 1963, the Colorimetry Committee of the CIE decided to supplement the then existing CIE illuminants A, B, and C by new illuminants more adequately representing phases of natural daylight. These new illuminants (D55, D65, and D75) were defined by a new approach suggested by Judd et al. [2] based on Simonds’ [3] method of reducing experimental data to characteristic vectors (eigenvectors) and calculating the relative spectral power distribution of daylight of any desired correlated color temperature.
