Bacterial diaper rash may be caused by several different organisms. The most common are Staphylococcus aureus (Staph), which also causes impetigo, and Group AStreptococcus (Strep), which usually is seen as strep throat.
A light-emitting diode (LED) is a semiconductor device that creates light using solid-state electronics. A diode is composed of a layer of electron rich material separated by a layer of electron deficient material which forms a junction.
LEDs create light by electroluminescence in a semiconductor material. Electroluminescence is the phenomenon of a material emitting light when electric current or an electric field is passed through it-this happens when electrons are sent through the material and fill electron holes.
