sd_single_led_Ohno2005
(peak_wavelength, fwhm, shape=SpectralShape(360, 780, 1))[source]¶ Returns a single LED spectral distribution of given spectral shape at given peak wavelength and full width at half maximum according to Ohno (2005) 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.
- Returns
Single LED spectral distribution.
- Return type
Notes
By default, the spectral distribution will use the shape given by
colour.DEFAULT_SPECTRAL_SHAPE
attribute.
