WebIn the spectral dimension of illumination, the most general view looks at the spectral density—the amount of radiation per unit wavelength interval. In terms of the four spatial quantities already considered, the spectral quantities are spectral flux, Φλ; spectral irradiance, Eλ; spectral intensity, Iλ; and spectral radiance, Lλ. WebNamely, the spectral range of irradiance from sunlight is from 300 up to 4000 nm, whereas the spectral distributions of artificial light are more narrow. For instance, artificial light emitted by incandescent lamps has a spectral range of 350 up to 2500 nm, by LEDs from 400 up to 800 nm, and by fluorescent lamps from 300 up to 750 nm [37] .
