Led luminance

NettetRoyal Blue is typically around 450nm. The bandwidth of a Royal Blue stretches out to around 400nm near UVA and hitting the limit of human advisably (about 400nm). Blue does get as close so it is still considered Luminous. Blue is visible so measured in Luminous units typically lumens. Some of Royal Blue wavelength spectrum is not … In photometry, luminous intensity is a measure of the wavelength-weighted power emitted by a light source in a particular direction per unit solid angle, based on the luminosity function, a standardized model of the sensitivity of the human eye. The SI unit of luminous intensity is the candela (cd), an SI base unit.
