Abstract: in this paper, we try to use the concept of the illumination design to calculate the illumination of arbitrary plane when a number of white-light LEDs have been assigned.
Reasonably to carry on the illumination design and construction is the essential condition to building safeguards.
In perspective of "green illumination", this article makes an analysis of prevailing trend of lamps with a brief discussion about green illumination design in sitting room, the bedroom and bathroom.
