colour.colorimetry.sd_single_led_Ohno2005

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

Generate a single LED spectral distribution with the specified spectral shape at specified peak wavelength and half spectral width \(\Delta\lambda_{0.5}\) using Ohno (2005) method.

Parameters:

• peak_wavelength (float) – Wavelength at which the single LED spectral distribution peaks.

• half_spectral_width (float) – Half spectral width \(\Delta\lambda_{0.5}\).

• shape (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 specified by colour.SPECTRAL_SHAPE_DEFAULT attribute.
