Fabrication of LED flood light from recycle material with high quality

Light-emitting diode (LED) is the light source that is incorporated in computer monitors! and screens, althoughl it can also be used as both amindoor and outdoor lighting source. In this paper, it is present the fabrication of flood light LED by currentl source control to get the best quality power. And, how can it produce from recycle material from old engine! and old computers? The main point how to produce it from recycles material to minimize cost, and high efficiency. Practically it done in Egyptl in electronic research institute and still! work from a long time till now.
