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!
Beautiful video, thank you!!!
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. 😭
That's one of the clearest descriptions of anything I've ever seen.
Very educational and clear. I'm really happy to know how these work now!
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
Or 640K of RAM@@Splits-man
thank you for the clear explanation
Nice clear explanation. Thanks for all the effort you put into these. And those graphics!
Thank you for a detailed yet easily understandable explanation.
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 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.
This was excellent! I had watched other tutorials before but this opened my understanding! Thank you!
Excellent video! I've known diodes and studied them. This is gold. 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.
Cant believe how good explained that was. I had it played fast forward on 2x and understood every single bit. Love it
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.
Okay this was so clear.. I had to subscribe. Amazing examples and explanation. My compliments.
that's the best description i've ever seen. Bravo
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?
This is a cool channel that my brain just absorbs every minute of the content.
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.
Beautifully explained. Thanks.
Former engineering student here... this was very nice work.
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
Best explanation i've had in this regard so far
One of the best explanation ever, thanks a lot
Great and much more in depth than most!
Nice information with very greatly explaining ability. Great work.
Thx for the brief explanation
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😅🌟
Brilliant. This channel has a bright future.
great visual description!
Very good illustration and explained
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.
Good work. Great animations. I understand LEDs now :)
Thank you! This was perfect!
i have been searching for this information forever. thanks for answering in such a simple video.
Any questions. ?
extremely aesthetically pleasing animations
I forgot everything after I graduated since my current job does not require any electronic knowledge. It is a very nice recap for me.
Thanks for the video. I enjoyed it.
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.
Sir,
Good demostration
Thank
tank you. excellent video dude.
Entirely superb! Thank-you!
To me LED is an amazing

Nicely presented.
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
Simply excelent explanation
White light LEDs are a type of "Flourescent" light. They work the exact same way that flourescent tube lights work!
YES, that is correct, so technically they are not LED lights, but Flourescent Lights. . . . Actually the phosphor is translucent, and allows some Blue light through, so they are a combination of Blue LED's and Red/Green Flourescent lights. 🙂
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.
very interesting videos , thank you
Fascinating!
It helped me alot
