colour.colorimetry.dataset.lefs Module¶

Luminous Efficiency Functions Spectral Power Distributions¶

Defines various luminous efficiency functions involved in spectral computations.

The luminous efficiency data is in the form of a dict of colour.colorimetry.spectrum.SpectralPowerDistribution classes as follows:

{'name': SpectralPowerDistribution, ..., 'name': SpectralPowerDistribution}

The following luminous efficiency functions are available:

CIE 1924 Photopic Standard Observer [1]
Judd Modified CIE 1951 Photopic Standard Observer [1]
Judd-Vos Modified CIE 1978 Photopic Standard Observer [1]
CIE 1964 Photopic 10 Degree Standard Observer [2]
CIE 2008 2 Degree Physiologically Relevant LEF [1]
CIE 2008 10 Degree Physiologically Relevant LEF [1]
CIE 1951 Scotopic Standard Observer [1]

Notes

The luminous efficiency functions are provided at 1 nm interval.
The mesopic luminous efficiency function is calculated using the CIE 1924 Photopic Standard Observer and CIE 1951 Scotopic Standard Observer luminous efficiency functions with the colour.colorimetry.lefs.mesopic_luminous_efficiency_function() definition and the data from colour.colorimetry.dataset.lefs.MESOPIC_X_DATA attribute that defines weighting factors dependent on the photopic luminance \(L_p\).
