# colour.sd_single_led¶

colour.sd_single_led(peak_wavelength, fwhm, shape=SpectralShape(360, 780, 1), method='Ohno 2005')[source]

Returns a single LED spectral distribution of given spectral shape at given peak wavelength and full width at half maximum according to given method.

Parameters: peak_wavelength (numeric) – Wavelength the single LED spectral distribution will peak at. fwhm (numeric) – Full width at half maximum, i.e. width of the underlying gaussian spectral distribution measured between those points on the y axis which are half the maximum amplitude. shape (SpectralShape, optional) – Spectral shape used to create the spectral distribution. method (unicode, optional) – {‘Ohno 2005’}, Computation method. Single LED spectral distribution. SpectralDistribution
