It was covered in the video but might have been explained better. A diode will not conduct until a small voltage (the forward voltage) is applied. Once the diode has been 'switched on' by this voltage it will conduct and a current will flow. In a LED it is the current flowing, not the voltage, that controls the light emitted. In addition diodes are not 'ohmic' loads, and are not self regulating, the current can rise to such an extent that the diode is destroyed (the graph at about 14:23 shows this well). This is why a current limiting resistor is required in the circuit.
LED's are basically amazing stuff. When I was little I only saw LED in red or green, and they were very dim, only useful for indicator lights on various machines. Then someone invented blue LED and now LED has basically replaced light bulbs.
Best video i have seen so far informing us about LEDs. Thanks very much for high quality content and the effort put into it. I really appreciate you supported your theoretical background together with circuit diagraghms and also making it on breadboards just to let us see how it looks. It definitely would tale a lot of effort and time. That is very much appreciated.
This is one of the best videos I've ever seen. Easy to digest for any level of familiarity of sciences, with amazing infographics. Keep up the great work.
Seriously? The pacing is almost rabid and the content should be able to do the work without the needless whoosh-zippy distracting stuff. Definitely made for the ADHDTV generation.
Another LED type that I learned about a few weeks ago is called an addressable LED. It’s a bit beyond this video, but worth noting for the advanced users as it allows multiple LEDs to be controlled at different colors each using only one signal pin on a microcontroller. It is a LED with an internal microcontroller that can be gotten as either RGB or RGBW and is controlled by a high low signal. The LEDs are chained in sequential order by their signal pins. To control them, a signal is sent containing the information for all the LEDs in the chain. The first LED removes its instructions and then sends the remaining signal to the next LED. These LEDs can be bought individually or in LED strips.
void of free electrons and holes, is crucial to how a diode-and therefore an LED-operates. It forms an electric field that controls how electrons flow, allowing them to move in one direction only. When an electron from the N-doped side moves across the depletion zone into the P-doped side, it releases a specific amount of energy, which is emitted as light.
Excellent video. Being an old TV, RADIO. Repairman in the 70’s I have a steep learning curve ahead of me. MOSFET was the cutting edge of the cutting edge when I started Medical School. Now at age 70, I am still seeing patients but am getting back into electronics. In my life as a physician, I met many veterans from WW2 and into the early 1950’s. Learned a lot once their NDA’s expired. Amazing what they were able to do with vacuum tubes! Now, something I would appreciate your expert opinion. I learned physics in undergrad, Kozarev’s theories, which he proved to a certain pin extent, were fully validated in the Mid to late 80’s and 90’s. The physics of his Spiral mirror are amazing but well beyond my math level. I found out last year of a recent experiment in the last 10 years, they were able to SEE the Pleiades where they currently are both with light telescope and radio-telescope when using the Kosarev spiral mirror in conjunction. The Pleiades are 1200 light years away. This would indicate that Kozarev’s mirror is able to receive tachyons or other similar particles. There is a documentary on UA-cam about the experiments that were tried in an area of low magnetic field near the North pole. Please let me know what your thoughts are on this scientifically proven but quire mysterious device. My name is Sergio AKA Dr. T🖖🏼
I knew nothing about how diodes work until i watched this. The amount of research that went into diode development must be astonishing. Well done you electronic brainiacs. 👏 👏
Truly thank you for this ..I have wounded my hole life the science behind the led but every time I researched I got the basics of power gose hear and light ...not a single person on this planet in 30 years bothered to actually go deeper... So truly thank you 💖
For a long time, LEDs could only be produced in the colors infrared, red, orange, yellow and green. It was not until 1990 that blue LEDs and thus also white LEDs could be developed. I know that back then cars used blue bulbs instead of LEDs for high beam indicators.
It was so hard, in fact, that the three Japanese men that discovered how to make one, Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura, won a Nobel Prize in physics!
I was pleased that your animation showed the correct electron flow direction from negative to positive. In electronics college our instructor demonstrated this with a piece of graphite and a piece of paper. With high DC voltage and the negative connected to the graphite the arc produced carried graphite particles to the paper as the arc continued through the paper to the positive electrode on the other side.
You are correct in that the electrons originate from the negative terminal and go towards the positive terminal But the electric field originates at the positive terminal and ends at the negative terminal. The direction of the electric field is opposite to the direction of the electron flow.
I like that too, practically it doesn't matter when thinking about circuits, but I would have loved if that was what I learned in school to begin with.
You should do a video on "Toasters explained - How toasters work...and why you shouldn't put silverware into the slots" from an electrical engineering perspective. The electrical engineering behind the average toaster is both fascinating and horrifying. The toaster is probably the single most dangerous standalone appliance in the average home. While microwave transformers are far more dangerous/lethal and the large capacitors found in A/C units can also deliver a lethal charge, you have to disassemble those appliances to enter danger territory. The toaster, on the other hand, can deliver a lethal charge without any disassembly and can also short itself out and even cause electrical fires. The toaster also has plenty to cover on the electrical engineering front despite just being a bunch of metal and wires.
excellent video! Just a couple notes. at 8:35, unlike what's mentioned, most monitors would not use LEDs directly in the subpixels, more commonly just as a backlight, although the color mixing mechanism is the same. second is that the white LEDs used in light bulbs don't mix colors like that, as implied at the end. they're simply blue LEDs with a phosphor coating. exceptions exist of course. these are really nitpicks though, and I'm sure they've been pointed out before. i hope you keep up the great work!
After 16:25, a few queries. Is the Silicon Semi conductor still doped with Al and P? With the GaAs and GaP semi conductors, is there still Si in the material? So there is Ga in the P type junction and a mixture of As & P in the N type junction? The ratio of 3:2 As:P gives you 1.7584eV?
As a person born with astigmatism and nystagmus, I despise LED's nowadays. They are practically blinding, burn images in my eyesight that lingers for a long time, and have horribly opaque halos around their source, which makes it impossible to see. One could say "lol don't look at them", which is nearly impossible since nearly everything have them installed anymore, so much of which don't have a method of diffusing or masking/shading the diodes. This includes streetlights, billboard displays, headlights/taillights, screens, stoplights, ceiling light strips, industrial work lights, spot lights, etc. How can one avoid looking at them when they're everywhere?
I have absolutely no reason whatsoever to learn about how LEDs work but your video was so good and so entertaining that I did it anyway and I don't regret it.
Thanks for this incredible video! I used your video to make a physics presentation, and it was insanely useful! I will recommend them your channel, and I properly marked your video as a source. Thanks for making such a quality content!

8:35 No, unless your monitor is OLED (and very few are), you will not see LEDs there, rather LCD pixels. Even if it is a so-called LED monitor, that just means it's LED backlit. OLED is used on TVs and 'phones but rarely on monitors because of screen burn issues.
If someone plonks a mug of coffee with "Watts up?" written on the side, onto your working tray, the tray will always tip to one side. but the led won't roll off - that's what the flat bit is for.
Great description! 👍🙏 Could you make a video about oscillators? I'm curious to learn more about them. Also, what is a photon? I can see the light from my remote control with my naked eye, does that mean I can see infrared light?
Humans can see infrared light under certain conditions. Infrared light has longer wavelengths and lower energy than visible light. The human eye is made of water, which absorbs infrared light at wavelengths just slightly longer than the deepest red color that humans can perceive. However, if infrared light is bright enough, and of short enough wavelength, then humans can perceive it as red. edit: that was bard, I am no that smart
I have been struggling understanding this since my untermediate school from now on i can explain to my brother. Thanks for your excellent expalantion. i was amazed.
3:46 That bulb has a step-down converter, never seen that before. The LED Edison style house bulbs that I seen have been chains of LEDS banks in series and parallel with almost no electronics aside from LEDS. I have cut the tracings on the PCB and re-configured the bulb to run off 12 or 24VDC instead of mains power. After I finish I can re-glue the dome back on and have an RV light.

There ate some LEDs out there where the larger plate (the anvil) is the anode. The flat spot is the only reliable method on through-hole LEDs to determine polarity.

Super in depth, while not talking over our heads.
It was too redundant -- it felt like 4 or 5 shorts edited together. How many times do we have to be told about the flat side of a diode?
@@christosvoskresye As many you need to learn
It was covered in the video but might have been explained better.
A diode will not conduct until a small voltage (the forward voltage) is applied. Once the diode has been 'switched on' by this voltage it will conduct and a current will flow. In a LED it is the current flowing, not the voltage, that controls the light emitted.
In addition diodes are not 'ohmic' loads, and are not self regulating, the current can rise to such an extent that the diode is destroyed (the graph at about 14:23 shows this well). This is why a current limiting resistor is required in the circuit.
I got here referenced from Derek's ( Veritassium ) video "Why It Was Almost Impossible to Make the Blue LED". So cool.
