Light Illumination Converter
Light illumination is the amount of light illuminating a point on a surface.
Illuminating sources can be natural (daylight) or from lamps, lighter, etc.
The definition of Light Illumination determines the amount of light that covers a surface. If Ø is the luminous flux and S is the area of the given surface then the illuminance E is determined by E = ∅/S.
I is the luminous intensity and S is the area of the source surface perpendicular to the given direction.
