Features and Advantages of a Good Illumination Scheme
Illumination
When light falls on a surface, the surface is illuminated and the phenomenon is known as illumination. Mathematically, the illumination is defined as the luminous flux falling on a surface per unit area, i.e.,
$$\mathrm{\mathrm{Illumination,}\mathit{E}\:=\:\frac{\mathrm{Luminous \:flux}}{\mathrm{Area}}}$$
Good Illumination Scheme
A good illumination scheme is the one under the influence of which the eyes of a person, using the light, do not feel any strain.
For example, if the light is too dim, then one cannot observe the objects properly. On the other hand, if the light is too bright, then eyes start watering and are made to open forcibly.
