Briefing the term LED LED's are the diodes that emit light when biased properly. LED's are available in a variety of colors, such as red, yellow, and green. Some, such as infrared LED's, emit light that is not visible to the naked eye. The color emitted by a given LED depends on the combination of elements used to produce the component. LED's are generally produced using gallium (Ga) and one or more of the following elements: arsenic (As), aluminium (Al), indium (In), phosphorus (P), and nitrogen (N). Some common element combinations are identified in data given below. Most LED's have a forward current (I)Forward limit of 100 mA or less. Compound Color Emitted GaAs Infrared (inv...
