Introduction to LED Diodes

LEDs, or Light Emitting Diodes, are semiconductor devices that emit light when an electric current passes through them. They are composed of a p-n junction, where electrons and holes recombine, releasing energy in the form of photons. This process is highly efficient, as it converts electrical energy into light with minimal heat generation. The development of LED technology has been driven by the need for energy-efficient lighting solutions, and it has expanded into various applications, including displays, medical devices, and now, university research.
