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!
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.
Underrated Content. Your clear and cogent explanation deserves more views, man. 😭
Very educational and clear. I'm really happy to know how these work now!
Nice clear explanation. Thanks for all the effort you put into these. And those graphics!
That's one of the clearest descriptions of anything I've ever seen.
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
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

Thank you for a detailed yet easily understandable explanation.
Excellent video! I've known diodes and studied them. This is gold. Thank you.
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.
This was excellent! I had watched other tutorials before but this opened my understanding! Thank you!
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.
Definitely the person who explained is a best visualiser....my god ...just blown away😅🌟
Best Explanation I've ever heard about any kinda diode. Hats off man
Cant believe how good explained that was. I had it played fast forward on 2x and understood every single bit. Love it
I had never imagined coming across such beautiful explanation. Your effort in producing such videos can never be less than the excellence of nobility 👏👏👏
That was an enlightening video on LED’s and Diodes. Thank you for sharing.
pun intended?
Excellent and to the point! I'll save this video as a handy reference.
Beautifully explained. Thanks.
This is a cool channel that my brain just absorbs every minute of the content.
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.
One of the best explanation ever, thanks a lot
Former engineering student here... this was very nice work.
Great and much more in depth than most!
Best explanation i've had in this regard so far
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
Nice information with very greatly explaining ability. Great work.
Very nice. It answered my question more than i expected!
That is great 😁
that's the best description i've ever seen. Bravo
This video is exactly what I wanted to watch.
Very neat explanation,thank you so much.
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
Thanks for the well animated explanation
thank you for the clear explanation
Very good illustration and explained
Brilliant. This channel has a bright future.
To me LED is an amazing
Electronics miracle,
the way explained
enabled me to understand the badics
so easily !
Keep it up, please.
Beautiful video, thank you!!!
Thx for the brief explanation
Good work. Great animations. I understand LEDs now :)
extremely aesthetically pleasing animations
i have been searching for this information forever. thanks for answering in such a simple video.
Any questions. ?
great visual description!
Well done, nice video.
Sir,
Good demostration
Thank
Amazing explanation
Nice video, thanks for sharing :)
Thank you! This was perfect!
Loved it... Thank you
Amazing video! 👍👍
Good animation, but the diode surface is not covered in PHOSPHORUS, it is covered in PHOSPHOR which is a completely different thing
Yes and No. . . . Correct, Basic LED's do not have any Phosphor. . . They radiate which ever colour their doping makes them work at. . . We only cover the LED with Phosphor for White light. . . The phosphor allows some Blue light through and converts some blue light to produce Red and Green light, so our eyes think it is White light.
Thanks for the video. I enjoyed it.
Nicely presented.
tank you. excellent video dude.
Very good video. Thanks.
It was verrry nice and helpful. thank you
Wow! Very interesting. Thanks!

Very well done!
Great animation and explanation well done
You are such a great orator
Very well explained, thanks.
Outstanding !
Nice video.
EXCELLENT DEMONSTRATION OF LED LIGHT . Thanks .
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.
Amazing video, Thank you
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
Very good explanation . Encouragement for those who in this field.👍
I forgot everything after I graduated since my current job does not require any electronic knowledge. It is a very nice recap for me.
This is very helpful
as simple as it looks but details of how it actually works is complicated, salute to those great minds who invented this "everyday use" tech.
great work
thank you
You deserve more subscribers man....
hats off
Subscription owned. Great video, thanks :)
Very good keep it up. ❤
Thank you very much for your wonderful simple explanation 🤩🌹💯
Thanks a lot sir

Awesome video , you got a subscriber ;)
Simply excelent explanation
It helped me alot
Maann!!! That's super awesome...........Good work.....💝💝💖❣❣
I am in high school and to be honest we haven't learned anything about diodes yet but I wanna learn more. And this is the only video I have found that explains what leds are in more detail.
Others just assume you know what a diode is
Thanks
Do you have any questions you would like to ask me, about Diodes or Transistors. ?
Real bright..Tks
