Everyone knows LEDs and knows how to use them, but ... how does an LED or light emitting diode work?

This is probably the best breakdown explanation of how diodes and LEDs work i have seen. Looking forward to using it to help electrical apprentices understand the internal workings of LED's. Thanks

same here. It always frustrated me when my trainers told me: "you don't need to know this" when I asked questions like that. I was always like: "How about you stop discourageing your trainees and let me decide how deep I want to delve into the matter". Today I had a Trainee myself and I taught him everything about AC and DC Motors that I could think of, encouraged him to ask questions and told him to never stop being courious and he was verry thankfull for that (I didn't have to do this but I always call that damage controll). Electro engineering is awesome and I hate how trainees get dummed down nowadays.

I was a project manager at EMI Research (UK) in the 1970s. One of my engineers had used one of the new green LEDs to indicate that his system had passed all fault checks. My boss, an assistant director, was appalled at the extravagance of using a green LED.

Transistors are very different, but do use two junctions, the main ones I used were n-p-n junctions so worked easier with +V supply voltages on the Collector. . . . Transistors are Current amplifiers, not Voltage amplifiers like Valves ( Tubes ) were, although modern FET Transistors are Voltage amplifiers.. . . The simple principle of using a normal BJT transistor, the most common type. . . Is that you put + Voltage onto the Anode or Collector and due to the junctions, no current ( electrons ) flows between the Emitter to Collector.. . But If you put some +V on to the Base, then that easily causes Current to flow between the Emitter and Base, which then opens up the path for good Emitter to Collector current flow. . . . Very typically you could get about 100 times as much Current flowing between Emitter to Collector, as the Current you made between Emitter to Base.. . We call that a current Gain or Hfe

I was fortunate to be a technician on a research vessel and was tasked to illuminate evenly split hard rock core samples. The area to be illuminated was only 40 mm in-depth but in order to achieve the depth of field which was specified by the design criteria, the intensity if the illumination required the light source to be very close. 100 mm. As light dissipates to the square of the distance, the very bottom illumination would have “fallen off” enough to be visually detected. As the intensity of LED’s can be increased and decreased without change in color temperatures, I was able to make an array of lights and varied the voltage to paint evenly from top to bottom. This would have been impossible with halogen, fluorescence or other types of illumination. LED lighting was key, however we had to match color temperatures of all of the lights in the array because of the lack of consistency in manufacturing. Also LED lights are extremely heat sensitive and will change color temperature over time. It is a newer technology and has its share of growing pains if accuracy and consistency is needed.

This is seriously good science at a level and with language that I can understand. color temperature was an early problem with LED light sources. the temp was "cold" and ugly. Quite quickly, manufacturers figured out how to add contaminants to give a warmer light.

Now that is getting far more into electronics.. .. Yes, VeriCaps. . . Going even further, we made Parametric Amplifiers for Microwave Receivers, using that principle.. . . A parametric amplifier principle is that you feed the signal in, when the Capacitor value is high, then you effectively pull the plates apart, reducing the capacitance value, which from ½C.V² will now have to increase the Voltage across that capacitor. . . So now you have a Voltage amplifier for very small, low level signals. . :-)
