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 through electroluminescence. Light is emitted when electrons and holes recombine in a material, most commonly a semiconductor. The spectrum, or color, of light emitted is determined primarily by the constituent materials of the semiconductor and by phosphors â chemicals used to coat the LED die.
