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.
Light Bulb Types. LED light bulbs or lamps utilize light-emitting diodes in order to produce light. LED is a âsolid-stateâ technology, which means that the materials used to generate the light are encased within a solid material. Practically, this translates into a lamp with a rated life much longer than those using non-solid-state technology (such as incandescent, halogen, and fluorescent).
