- 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
I have very similar views so there is no need for a duplicate comment!
@@yousafzaiaa7453 Me too!
Me too
Same
No
I casually have seen many many videos of diodes and semi conductors, but this video is explicit and straight to the chase and I've finally understood
This is the best explanation of semiconductors and LEDs I've ever seen. Exceptionally well done.
Thanks!
Very educational and clear. I'm really happy to know how these work now!
You tube is awesome lol. As an industrial electrician, I don’t normally need to know how components work at this depth. But, I now I can’t stop learning more and more 😂👍
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.
Nice clear explanation. Thanks for all the effort you put into these. And those graphics!
As a physics teacher I say: Grand way of explaining the basics of this phenomenon! Thank you for your great animation/ rendering! Michael B. Butter
After reading about diodes for over 50 years, I finally get it. One has to truly understand what happens at the subatomic level. What a brilliant presentation. So very well done, thank you.
That's one of the clearest descriptions of anything I've ever seen.
Excellent video! I've known diodes and studied them. This is gold. Thank you.
Cant believe how good explained that was. I had it played fast forward on 2x and understood every single bit. Love it
Beautiful video, thank you!!!
Underrated Content. Your clear and cogent explanation deserves more views, man. 😭
thank you for the clear explanation
This was excellent! I had watched other tutorials before but this opened my understanding! Thank you!
Thank you for a detailed yet easily understandable explanation.
Best Explanation I've ever heard about any kinda diode. Hats off man
Excellent and to the point! I'll save this video as a handy reference.
Thx for the brief explanation
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.
Beautifully explained. Thanks.
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.
How you are still alive
@@noobda597 Don't smoke, ride a bicycle daily, inherited the right DNA. Plus I was younger than most of my engineers at EMI.
And some extremely important scientist back decades ago sad he couldn’t see the need for any more than 3 computers. 😉
ok
Or 640K of RAM@@Splits-man
I had never imagined coming across such beautiful explanation. Your effort in producing such videos can never be less than the excellence of nobility 👏👏👏
Thank you! This was perfect!
That was an enlightening video on LED’s and Diodes. Thank you for sharing.
pun intended?
Okay this was so clear.. I had to subscribe. Amazing examples and explanation. My compliments.
That's the explanation we all wanted. Thank you so much bro
This video is exactly what I wanted to watch.
Very neat explanation,thank you so much.
Great and much more in depth than most!
great visual description!
Best explanation i've had in this regard so far
One of the best explanation ever, thanks a lot
that's the best description i've ever seen. Bravo
Entirely superb! Thank-you!
To me LED is an amazing
Electronics miracle,
the way explained
enabled me to understand the badics
so easily !
Keep it up, please.
Very nice. It answered my question more than i expected!
That is great 😁
Definitely the person who explained is a best visualiser....my god ...just blown away😅🌟
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.
ledI make LEDs.
i have been searching for this information forever. thanks for answering in such a simple video.
Any questions. ?
Thanks for the well animated explanation
Thanks for the video. I enjoyed it.
extremely aesthetically pleasing animations
Amazing video, Thank you
Great video...Thank you! I didn't realize how much we knew about LEDs back in the 60's. Or 70s - recent, actually. Technology was mostly there, it seems... but not quite.
This is a cool channel that my brain just absorbs every minute of the content.
Nice information with very greatly explaining ability. Great work.
great work
thank you
Fantastic Video! thank you SO much!
Fantastically explained
Brilliant. This channel has a bright future.
Excellent explanation in order to all parameter considered
Nice video, thanks for sharing :)
Good work. Great animations. I understand LEDs now :)
Very good illustration and explained
Great video, thanks👍
Super explanation!
Subscription owned. Great video, thanks :)
Hello, thanks a lot for this brilliant explanation! I finally grasped, how diodes, transistors and LEDs are working. Really excellent, this video. Greetings from France, Manfred
I make led lamp beads.
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
Very well done!
tank you. excellent video dude.
Very well conected topic with Animation to get to the point more compehensive ...
Very well explained, thanks.
Fascinating!
Wow! Very interesting. Thanks!
Loved it... Thank you
Great stuff. Subscribed.
Nice. Didn't learn anything I didn't ALREADY know...lol. seriously though, nice breakdown. Very informative.
Thank you for these explanations and this superb animation, I think I have more or less understood, let's say that from here a dozen times it will be better. Ricco, from France
It was verrry nice and helpful. thank you
