Description

Properties
Illuminance is the total luminous flux incident on a surface, per unit area. It is a measure of the intensity of the incident light, wavelength-weighted by the luminosity function to correlate with human brightness perception.
$$E_v = \frac{d\Phi}{dA}$$, where $$d\Phi$$ is the luminous flux incident on an element of the surface with area $$dA$$.
