colour.colorimetry.sd_single_led_Ohno2005#

colour.colorimetry.sd_single_led_Ohno2005(peak_wavelength: float, half_spectral_width: float, shape: colour.colorimetry.spectrum.SpectralShape = SPECTRAL_SHAPE_DEFAULT, **kwargs: Any) → colour.colorimetry.spectrum.SpectralDistribution[source]#

Return a single LED spectral distribution of given spectral shape at given peak wavelength and half spectral width \(\Delta\lambda_{0.5}\) according to Ohno (2005) method.

Parameters

peak_wavelength (float) – Wavelength the single LED spectral distribution will peak at.
half_spectral_width (float) – Half spectral width \(\Delta\lambda_{0.5}\).
shape (colour.colorimetry.spectrum.SpectralShape) – Spectral shape used to create the spectral distribution.
kwargs (Any) – {colour.SpectralDistribution}, See the documentation of the previously listed class.

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.
