Application 

Illuminance (Luminosity) of an object is the luminous flux per unit time is within the acceptable face to face, using accepted flux per unit area is represented, expressed in units of lux (Lux, lx), namely lm/m². 1 lux is equal to one lumen (lumen, lm) luminous flux uniformly distributed on the light intensity 1m² area.
