In the first reference, the author explains how LEDs actually produce light. As it states, on the contrary to other light sources, LED lighting is of kind “cold”, meaning that the light that is produced is not actually a result of heat but rather through the movement of current which results in the movement of electrons (from the layer that has excessive electrons ) toward holes (layer which lacks electrons) that cancel one another, and generate light in the end. The important concept though, is that it states “The wavelength of the light and hence its color is based on the materials used.”
