Luminous Intensity

Physical Sciences

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 cited article states that the SI unit of luminous intensity is the candela, an SI base unit. It is the quantity that describes how bright a source appears in a given direction, as distinct from the total light the source emits in all directions. Units such as the candela are grouped under this quantity.
