Luminous intensity
Visible light per unit solid angle / From Wikipedia, the free encyclopedia
This article is about photometric light intensity. For other types of light intensity, see Light intensity (disambiguation).
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.
