colour.sd_single_led#

colour.sd_single_led(peak_wavelength: float, 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 single LED spectral distribution of given spectral shape at given peak wavelength according to given method.

Parameters

peak_wavelength (float) – Wavelength the single LED spectral distribution will peak at.
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_single_led_Ohno2005()}, See the documentation of the previously listed definition.

Returns

Single LED spectral distribution.

Return type

colour.SpectralDistribution

Notes

By default, the spectral distribution will use the shape given by colour.SPECTRAL_SHAPE_DEFAULT attribute.
