colour.sd_multi_leds#
- colour.sd_multi_leds(peak_wavelengths: ArrayLike, shape: colour.colorimetry.spectrum.SpectralShape = SPECTRAL_SHAPE_DEFAULT, method: Union[Literal['Ohno 2005'], str] = 'Ohno 2005', **kwargs: Any) colour.colorimetry.spectrum.SpectralDistribution [source]#
Return a multi LED spectral distribution of given spectral shape at given peak wavelengths.
- Parameters
peak_wavelengths (ArrayLike) – Wavelengths the multi LED spectral distribution will peak at, i.e. the peaks for each generated single LED spectral distributions.
shape (colour.colorimetry.spectrum.SpectralShape) – Spectral shape used to create the spectral distribution.
method (Union[Literal['Ohno 2005'], str]) – Computation method.
kwargs (Any) – {
colour.colorimetry.sd_multi_leds_Ohno2005()
}, See the documentation of the previously listed definition.
- Returns
Multi LED spectral distribution.
- Return type
Notes
By default, the spectral distribution will use the shape given by
colour.SPECTRAL_SHAPE_DEFAULT
attribute.
