As an electrical engineer, it's not often you can watch a youtube video about electronics without being misinformed - but this one isn't one of those, it's very well explained and accurate. Well done.
Are there any channels that rarely do this?
As an Archaeologist, I like this video for its accuracy.
@@theflamethrower867 Rarely misinform?
ElectroBOOM is really fun and he knows his craft very well.
@@MCMaterac he's difficult to follow, even if he knows what he's talking about
@@johannsmith5697 Haha, well... his videos are a bit uneasy, if that's what You mean ;) Also, if he goes technical, he rarely explains the stuff in detail. So Yeah, I think You're right. Still, his content is pretty entertaining and not w/o educational value. I enjoy.
Fun fact: all diodes of all sizes and types emit infrared light when current passes through them. LEDs are just specifically designed for emitting light. The process also works in the other direction. If you expose a diode to enough light radiation, the photons knock some of the lower energy electrons to a higher energy state, which induces a current in the diode. Solar panels are diodes, and if you apply a current to them, they will actually emit infrared light as well. And yes, this means that all types of LEDs do also produce a voltage when you shine a light on them. It's a very small voltage, but it's there.
Edit: I should add that LEDs are the only type of diode that can emit other wavelengths of light in addition to infrared. "Regular" diodes and those used to make solar panels produce infrared light. Infrared is not used to produce other colors in LEDs.
Steve Mould made a video on this. Here's the link: th-cam.com/video/6WGKz2sUa0w/w-d-xo.html
Photoelectric effect right?
They emit not ifrared, but ultraviolet light
Im very pleased to see MrRedstone teaching us real life redstone.
It's just like fluorescence: everything fluroesces at all wavelengths. It's just that unless you're looking at a specific type of material, you won't be able to detect the emission :)
I am an electrician but never saw such a clear and thorough explanation of how LED works.
Awesome video, thank you!
I wish you were a professor at my school. The best cut to point explanation, with progressive well-organized narration. Thank you so much for you work!
Matt, I suggest you include your " item search titles " for the listed items to purchase. Occasionally they go out of stock and finding replacement from other online sources become challenging at best. Excellent work as usual this is and thank you for sharing.
But he'd be losing on that affiliate revenue. There's no incentive for him to give you an option to buy shit from a place he doesn't get money from
@@centralintelligenceagency8811 Then you don't know Matt. FYI, he doesn't need dime or dollar generated from affiliate sales.
I know I prefer to shop for electronics on aliexpress. It's much much cheaper than Amazon and many of the items are the exact same just without the sucker overhead.
@@Alacritous I too like to try to order experimental electronics from Aliexpress (things I would like to play around with but don't need right now). Amazon is much better for getting things right now although I do not like Amazon and try to limit purchases from them.
@@blindpilot9403 if he doesn't need it, why does he do it?
As an artist I find it really hard to learn new knowledge or processes without understanding them first, so when I was trying to learn to replace the lightbulb in my drawing light box with LEDs I found it hard to follow along with the tutorials. Thankyou for this! You have helped me understand much more :)
I love how you take a more instructional approach in this video actually showing the electrical principle behind and how to solder... and is explained so well... wow
Without a doubt, this is the best, most perfectly concise explanation of how to work with LEDs that I've ever seen. Thanks so much!
This was absurdly amazing.
Seriously, this is one of the very best channels on YT
I was searching instructions for a project I wanted to build and lost about 3 days in time searching worthless DIY youtubers. Sir, someone mentioned you in a forum as a great instructor for DIY. The project has already ended with some more additions to the initial plan. I finished my daughters UFO treehouse Thanks to you. We even hang out with my wife when our daughter is at camp for the summer. With your instructions we created a replica of the part of the galaxy we have above our house. And its solar powered. Again Sir, you are the real deal and thank you :) Cheers.
P.S. Sorry for any mistakes in syntax or grammar. English isn't my native language.
That's such a cool concept for a tree house!
Please keep creating more projects if you are free. Your projects inspire many people like us and keeps entertained during these times. Thank you!❤️
Thank you! This video is the first one that straight on explains why there is a need for current limiting. Its the led itself that draws the current in amounts that could be way beyond its handling capabilities. Nothing really to do with the device powering it up. Rarely people say more that it just needs current limiting so it doesnt burn out, not the reason behind it.
If my physics teacher cared even 30% as much you do, i'd be a damn scientist by now.
They dont ever teach you the cool stuff. Then again i didn't think LED's were cool until i was an adult.
@@TheGalacticWest I’m a kid and I think they’re cool.
@@TheGalacticWest They never teach you the cool stuff in school, you have to find the TH-cam geeks to have the real fun!
the only thing more vibrant than high powered LEDs is Matt's personality :D really it's at least half the reason I watch these videos for
I began working with LEDs in 2009. I was the most knowledgeable guy for many miles around but life took me in a different direction. I still do some art with them but there's been so many improvements, new designs and people getting involved with them-like yourself and I'm sort o fin the dark (pun intended) these days. However you have shined some new light (yep-another pun) on the subject. Bravo. Good job and Thanks
I have been wanting for a video like this from Matt Perks and now I must say I'm impressed by the quality of what he's produced. Matt kept it quite simple yet he was able to correctly relay all the fundamental principles of LED lighting.
I'm a picky electronic engineer who's been designing LED-based light sources and I couldn't fault anything in this video. Yes, I would have been even more explicit in the proportionality between current an light emitted (and how one's priority should be controlling the current rather than the voltage) but the concept was clearly mentioned.
Now I'm eager to see a few examples of affordable controlled current sources. It seems that there are far fewer of this kind of modules available for DIY.
One last thing: how can I get hold of decent lenses from up-cycle stuff?
Awesome videos you have! I might point out however, that using a voltage regulator circuit with a current limit mode is kind of topsy turvy, it's better to have a circuit configured as an adjustable current regulator which can put out enough voltage at the LED's rated current, because these are current-sensitive devices, and therefore you will not need two modes of operation, nor will it "run away".
You've inspired most of my LED projects, thank you so much for these types of videos!!!
Thanks Matt, clear and easy to understand. I'd love to see your take on electroluminescent lighting and the possibilities. They look really cool
I'm an RV contractor and this vid has inspired a new line of service for me; making 12V light fixtures. 1000 Thx!
Outstanding application
Matt's such a decent bloke, out of respect I leave my mouse alone and sit through his Blinkist ad. It seems the honourable thing to do.
Not that it benefits him at all as the ad is embedded to the video. I also tend to watch new ones like these as I find it curious how naturally/unnaturally each TH-cam can present the promoted product or service. But skipping them is no harm to the producer.
Imagine this being your teacher, that would be perfect.
Don’t underestimate my laziness
@@hallobre lmao
Yeah, depending from what his profession is, he really could be one for a while, there is another guy, Louis Scully from the channel Scullcom Hobby Electronics, he did it and he is a dream of a teacher, I mean I never was his student but how he explains everything is just amazing, I have an IQ of 138 but never got a high school grade because I can't learn what I can't bring in to practice immediately, my brain just refuses to save informations then, but man if I had such teachers I would have loved school instead of seeing it as a massive waste of my unique lifetime and the place where they mainly just want to make me to obey and not to question what I am told to do.
@@Wilson84KS I have an IQ of over 9000.
Seriously, I never understood a thing back in school. This channel has opened doors for me.
Mr. DIY perks no matter how hard the project is and never doing anything i absolutely love your video not only entertaining but has actual good information.
For that thank and may your channel become ever more stronger.
💐🙏
Fabulous, really easily understood explanations. I now understand about 'constant current' for the first time!! Keep these coming please. Good work.
"A big long standing project i have planned is mimicking the sun"
Say no more

Next video DIY Perks video: DIY light a Black Hole in your favourite Galaxy.
Hey guys, today I'm going to show you how to build a cheap, working fusion reactor using nothing but parts you can buy from your local hardware store. It even can be mounted to any traditional tripod mount!
@@graysonsmith7031 amazing, conventional fusion reactors you can buy online never have the tripod feature.
So he will invent unlimited power from LED...
Rough draft
"Sun" LED > diy solar panel > diy battery bank
He's playing God now, what an absolute madman.
The next step is working on reverse LED lights that mimick black holes and absorb all light around them.
It is remarkable to see how the LED has evolved from replacements for incandescent and neon indicator lamps, to serious lighting. I never expected to see LED used as replacements of strobes and incandescent beacons on emergency vehicles.
i think you did hate led? are you love old incandescent? i know incandescent is very poor hot and 1,000 hours and cant saving battery, led is can color cri 85 and 90 and saving battery, 25,000 hours, led is can optin soft white and warm white of eyes good, i was see russia train 2010s of led to 10 years later age old today led is still power working lasting than incandescent, wow! incandescent is cant power battery phone! why are you didnt know? incandescent and halogen is very poor, i didnt like cfl, led is can is the future more last.
This is weird, I came to the channel because I was looking at making my own floodlight setup yesterday. Didn't find what I was looking for then you release this the next day. Magic.
Please do a video explaining different methods of controlling addressable RGB LED strips. You always explain things so well!
The subject (lumens per watt) made me research how WWII air raid spotlights of 70 years ago worked and how they compared in brightness/cost to our modern LEDs. Not on-topic for your channel, but worth a google for anyone who would like to know how 'they' achieved long throw light beams (miles), and at what $ cost, so long ago, and how it still leaves our modern LEDs standing !
Every single video here ,not even one fail to remind me this channel is totally worth the subscribe and notification.
Watching your videos encourages me to do diy projects of my own. Thank you
I just love your videos. They are quite professional and you explain things really well and accurately. Thanks for sharing! 😀
Perkz: Just look at all that light (points light to me)
Me: 😵😵😵
lol
Now u'll need led eyes
@@ichankomo8767 why have led eyes when you can ghost in the shell camera eyes?
I love it when he says 'we'll look at X later' when the video is only 15 mins long 😁
I will watch anything that this guy uploads. Such a calming and intruiging vibe this man creates. Great video as usual!
You make a perfect teacher. You already have the best of the best qualities
Great video, and thanks for making this @DIYperks. However and although a bright LED is a lot a fun for cyclists, because of the powerful directional nature of the LED semiconductor, LED headlights for cyclists are a complete menace to both motorists as well as pedestrians, especially when they flash. I've noticed that when driving (I also cycle, and think it is important always to have some form of lighting on a bike after dark for reasons of safety), there is very much a tendency to keep focussing on the bright light of a cyclist rather than paying attention to the actual road, or what may be in it. I really wish more cyclists would consider this more when choosing lights for their bikes, as we all hate drivers who have the same power on their headlights. So why should cyclists be an exception to this rule?
Would you be able to continue your led adventures? Circuitry is quite far removed from my skillset, but I would love to be able to make custom grow lights for my plant wall. Makes retrofitting a much easier task
I second this request for the same reason. Indoor vegetable growing does not have a lot of educational resources that I have found online and none as well put together as your videos are.
I highly recommend a pair of 3x glasses
also a circuit board is like a long string you just
need to tie the right knots
Thanks for the simplification, that was the absolute best 'For Dummies' video I've ever seen!
Great video as always! The explanatory content about LEDs is just fantastic.
bro at this rate this man is going to teach us how to make a nuclear warhead in just 3 months
forget nuclear, making your own viruses with a CRISPR kit is the way to go in 2020
Hey Mat, nice deep dive on the electro-chemistry of LEDs!
-Ken
I've often wondered how you can test the brightness of powerful LED's at home without expensive equipment.
Thank you for demonstrating the simplicity of this complex vexation by simply blasting the light into your ocular receptors.
Hi Matt, I like the way you are presenting your projects - not too complex but also not boring, keep doing it please! Subscribed. Speaking of powering the LED I'm missing some information about using PWM for lowering the current consumption and thus heat flux reduction. Would you maybe extend your topic therewith? Cheers
Your shirt is doing crazy Moire Patterns on my screen lol.
So I was just watching his video whole day and he just uploaded a new video 🤣
Perfect timing
Thank you for this video Matt!! I start to understand the LED lighting better. I want more videos like this! Thanks!
Thank you for making this video. So easy to understand the leds. Can't wait to make my own with your instructions.
I won't mind a Netflix series of this guy where he is a detective/superhero/person who uses surrounding parts to make a tool for fighting evil.
You mean MacGyver?
MattGyver.
We could take bets on when one of the big productioncompanies finds out about this guy. The question is not if. It is when and who.
Seems like MacGaver with extra steps
Elon: "Gonna plant some chips in peoples heads..."
Matt: "Hold my beer, we're gonna mimic the sun."
G2V Optics already has
Thanks for showing us all on TH-cam the ins and outs of LEDs.
Excellent video! This covered all of the information I was looking for and some that I didn’t even know I needed. Thank you!
TIL that "warm white" is lower on the temperature scale than "cold white".
because "cold white" light emission requires much higher temperature in the old filament. The hotter the wire, the brighter it glows and therefore the "whiter" the light becomes.
14:00 you mention wanting to make an LED mimic the "distance" of the sun (the fancy pants way of saying that is collimated as I'm sure you know but didn't want to explain for time). While I'm sure you've found a way to do this part already, a really cheap and simple way I would imagine doing this is getting a bunch of those coffee straws together and putting those in front of the LED. This technically just blocks the unparallel beams and is less efficient than lenses or whatever you are doing. But I think this would be a good quick-change filter for a light source and would be good for maybe 40% of use cases.
He's probably gonna use a Fresnel lense like he already did
@@Deus_Almighty yeah, those aren't very expensive and block less light. But hear me out... c o f f e e s t r a w s.
Take it up a notch - lets consider condensed gas with ratios similar to atmos into a gel coating that mimics blues.
@@justinjanes3431 Carbon Nanotubes :)
I remember reading/seeing a simulated sky light. You could put it in a basement if you wanted and you really couldn't tell it was simulated. Only issue was that the sun's angle wouldn't change. You had to pick what permanent angle you wanted ahead of time for it's construction. It really looked just like the sun streaming through a skylight. Shadows were sharp like you would expect as well. What made it special was that it also simulated the blue sky effect. I tried to get one of them but they were super pricey. I think/hope that's what he's going to DIY. I think it was innerscene.com/
LED's are the best invention in the 21's😂 Love your videos! They're so informative and nice to watch. The quality is on such a high level❤
Greetings from Germany
Thank you so much man. Always learning something new from you and be able to work on something new. Been working on laptop to home pc setup lately. Love to get inspirations from you
as someone from the Netherlands, do NOT mount these on your bicycle. You'll blind any oncomming traffic and risk car drivers crashing into you.
I think it's best to adjust the brightness for bicycle use. This should save battery & not blind others.
Aim them downward or ensure the top half is covered by an appropriate guard. Don't know how the Netherlands is relevant, bikes and cars exist most places...
I think wherever you live putting one of those in a bike is very unsafe
That’s already a concern with pretty much any handle bar mounted light already available on the market. The handlebar headlight I have now is brighter than any flashlight I’ve ever owned. My dads is about half as bright but still quite bright when seen head-on. It’s all about mounting it at the proper angle, same as the headlights on cars.

After a long time i watched a complete video without skipping even a single second... Thanks for all the info👍
This is an incredible modular type tutorial, more please!
This dude has carried my DT gcse bro
i like how i can learn more in the internet than in my actual classes XD
The background story to Kelvin values was fascinating. I can't believe how I haven't heard it before even while being very conscious of the different values the last 25 years!
I can't tell whether I love your voice more or your videos. Both are incredible.
as the date of this post: "You did it, you crazy sun of LEDS, you did it."
That is the most beautifully pronounced "custom" I've ever heard.
Where from you are brother?
Bardzo dobrze wyjaśniony proces pracy LED. Super lampka.
So much information about LED in one single video. I have wondered about and searched online for a lot of this info about LED. Thank you so much.
This guy is Mumbo Jumbo in real life!
Star war's I love it
He's no Hermit, but he does like his craft

While this is a cool tutorial, PLEASE don't recommend using such high power LEDs with quite a lot of stray light to be used as bike lights. If such a thing comes into your sight at night, while you are using maybe a good ol' 10W bulb or a small LED light yourself, you're pretty much screwed as you can't see anything. Please only use lights with a sharp stray pattern at the top, so it doesn't blind anyone more than 20m away or so.
Otherwhise, well done, always enjoying your videos :)
Hey, your videos are amazing. You really provide detailed information and it helps in understanding the underlying concepts of the DIY things you make/device/invent. I have one request if you can do a video on how to make DIY freshwater aquarium LED light with a full-spectrum of light for freshwater plant growth. thank you!!
Your videos are amazing, the first one I watched was the invisible pc desk and I immediately subbed because it blew my mind, keep up the amazing work I’m excited to see future projects.
Maths fact: With a ~26000mAh power bank and a 10W led, You can get between 7 and 8 hours of light.
It depends on the Voltage. At about 3.2 V you are right. Double the Voltage and the time doubles b because the product of Ah * V = Wh doubles
And you are assuming not only 100% efficiency but also that the mAh rating is in reference to the 5V output and accurate.
5 V would be the nominal voltage of a USB connection, but fast charging protocols allow up to 20V. And some docks produce almost 100 W over USB-C.
26,000 mAh and the math fact claim are so disjoint that the word silly springs to mind. Another factor in the 7 to 8 hours is if the battery is drained in one continuous draw or not.
I hate that manufactures etc often advertise amp hours. That only makes sense if you know the voltage it is calculated with. for example if usb battery using it's internal cell voltage or its output voltage of 5V (and there are different usb output voltages too nowadays). Anyway i think that even when you know that, Ah still doesn't tell how much power you can actually use. I hope that at least in EU, (someday) there will be some law forcing manufacturers announce those figures as Wh (watt hours).
You are forgetting the double conversion you're doing: from 3.7V of the LiPo cells to 5/9/12 and then to the LED's voltage. Here you are losing about 30% energy.
This led man !!!! Look at his room full of led
Fascinating video - I have been an Electronics engineer for years, and I have learnt something.
Wao this guy has it all.Talent,the perfect type of voice for his videos,creativity and great personality.
Why did the name change from "An introductory Guide to LEDs" to "Building DIY LED lights"?
Idk, keywords maybe, a lil bit catchier
I've never been this early 🤣
I have been always early
me too
Never have I ever.
Hi! all your videos are awesome and we learn a lot from them! I made some projects with LED, getting inspired from some of your videos and one think that I think that's very important, specialy for making lights for video it's about flicker. I had to try with diferent kinds of regulators to find one without flicker.
We got a little indoor herb garden for a gift. I figured it would have one of those big incandescent grow bulbs inside, but it's just tiny little LED bulbs. I was unaware such a thing was even possible. Thanks for the informative video.
I have made a 60W LED but its flickering how come i fix it?
For the first time got notification this quick
Sooo much knowledge in single short video. Awesome job
Explaining what you work with in detail like this is a great idea considering that your other videos seem more like "preffesional production behind the scnenes" than DIY, cool Video.

Superb, I'm starting to set up a TH-cam studio on a very tight budget. Have the camera and software. This helped me to work out what I am going to do about lighting.

You are not just a youtuber also you are a good teacher as an electronics student your vedios are very much helpful and it is so simple to learn. Thanks bro I love you channel ❤️🥰😍
Dude, u didn't make a single LED.........
considering its so simple...
Whoever you work for isnt paying you enough matt
i love the content keep it up
thank you
Bright and brilliant presentation.
The light you built is very similar to how new car headlights are made, really fascinating love it!
Thanks for the knowledge on the meaning on Kelvin color temperature
Thanks Matt...enjoy your presentations
I did a deep dive on diy led walls made from led tape! I was surprised to see the limited options, 1 get a decoder and use dmx or use Arduino to control one strip. Thought of your channel and that you might find it interesting! I have a feeling you would have a much more creative way to accomplish an led wall with a wide variety of functionality! Anyway thanks for the inspiration!
The mimicking the sun project idea would be a great video. Also, a COB-based grow light would be a great video. Videos with the Edison style LED filaments would be great, too. Love your work!
As a hobby gardener breeding chilis and bell peppers (and therefore needing an isolated area devoid of unwanted pollen) they work great, 20-50 Watts per m² is plentiful and the LED(s) should have a CRI of 85 at the very least since pretty much every bit of the spectrum is somewhat necessary for a plant to metabolise/convert specific nutrients or cell behaviour.
Make sure to utilise a reflection cone and it would be best to include reflective walls in your indoor area (most white stuff is better than silver-ish stuff, reflects more of the spectrum) to get the stray light down to the lower leaves. If you construct it like a wardrobe/cabinet make sure to plan for some way of ventilation - those cobbs can warm up any small-ish enclosed space rather quickly and moisture will build up in such a warm environment fast
