ABSTRACT
Reexamining the classical notion: In the classical concept, rst, the source is localized at a small region. Second, the light is abundant in the neighborhood of the source and goes down as one recedes away from it. More light is provided at locations that appear likely during inceptive design to be spaces for performing precision tasks requiring meticulous attention and exactitude. Once allocated, these locations cannot be changed. erefore, in order to meet the wide-ranging, indeed endless, user requirements, it is evident that the light sources must intrinsically oer enormous design exibilities. e above notion of light source must therefore be reinspected after the availability of ingenious light sources.
