  • 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.

    • Thanks

    • Yes video link: ilaward.info/the/wyd-w/0H6ilWiKtIDJgJw

    • Da fuk is a phosphor 😂

    • Do you think he missed something? Hahaha jokes this was a great educational class

  • 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.

    • @MrRedstone I believe someone had a misconception of how CRTs work.

    • @imightdoyoutube That's definitely doable. I've seen some interesting stuff done with LEDs as a power source.

    • @Debarka Damn, this is an old chain. What happened here? Looks like the comments were deleted.

    • @Abu Bakar yes

    • Am I the only one who read diode as Dildo?

  • 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.

    • @Central Intelligence Agency For revenue, 1.2 + million views, be it ad rev and or patreon's. More than likely as A patreon member he gives much more detailed info to these projects.

    • @Central Intelligence Agency alot of affiliate links will give the person money even if they don't buy the item that the link was for, but buy something else from the site in a certain amount of time after you click the link

    • @Alacritous the good part about it is that there are some manufacters and can make you specific parts that you need and is the same quality.

    • @Central Intelligence Agency because he can!

    • @Blind Pilot if he doesn't need it, why does he do it?

  • "Have you ever wondered how LEDs work and wished you knew more about them?" YESSS! YES I have and so have I wished.

    • @Alex H. oh wow i didn't even realise my comment had 1k likes! Thank you everyone.

    • I’m your 1k like! Enjoy

    • 😂

    • An LED is a type of p-n junction diode which emits electrons in the form of light when it comes under forward biased connection.

  • I am an electrician but never saw such a clear and thorough explanation of how LED works. Awesome video, thank you!

  • This is a great video, love the way you explain every detail. I prefer slightly underdriving the LED's. IE, if an LED is rated for 60mA, I would run them at 50mA . LED's are a lot more efficient if slightly underdriven and will last a lot longer also, without losing much of the maximum brightness. Your channel has inspired a lot of projects, and a lot of thinking. Thank you :)

  • Excellent video with a lot of good info crammed in and as you say, just an intro to the intriguing subject. Helpful to now understand how they achieve the various white balances. I've been buying a few torches recently, been years since I bought one so I was well out of date with the tech and there is so much choice so it's a whole subject area that I had to spend a lot of time looking at before even deciding just what to pick to try out. Anyhow I ended up buying 6 different torches in a week and they are all very good in their own way. I guess I thought just get the collection out of the way and have it done and hopefully no more for a long while. I had initially just wanted a simple wind up LED torch for around the house with no batteries to worry about but was ensnared once I started looking. I believe there are a lot of people with rather larger collections but in my bunch I found one I like and think is most suitable for me and it uses a usb rechargeable 14500 (AA size) lithium battery (battery has inbuilt charging circuitry so just plugs via a lead into usb directly) which was something else new to me and works very well with no need for a separate lithium battery charger. Means the torch can also use standard AA but at lower voltage than the lithium. Still nice as I remember torches of long ago and they were lets just say. not nearly as good as now. That's a nice lamp you made btw.

  • 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.

  • 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?

  • 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".

  • Hi! Really helpful tips! Loved it! I'm trying to do a studio LED light of 50w using a COB led... I'm using a proper driver and heatsink and everything is working fine (thanks to your tips) but I really would love to have a way of dimmering it without introducing flickering... I really could use your help haha

  • Imagine this being your teacher, that would be perfect.

    • Seriously, I never understood a thing back in school. This channel has opened doors for me.

    • @Wilson I have an IQ of over 9000.

    • 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.

    • @hallobre lmao

    • Don’t underestimate my laziness

  • 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.

  • Could we get a DIY build using the 1500W COB in an Aputure 600D type form factor? With Bowens mount included and everything? Even if water-cooled with a computer AIO in order to reduce size compared to air, would be a very cool build. I know you've made some setups with it that technically work, but a proper super well designed sleek build would make for a great video.

    • Would love to see it go up against an Arri M18 HMI

  • I've only just discovered this channel and am very impressed indeed by the projects. Unfortunately, I don't know much about electronics, but am wondering if the voltage regulator demonstrated in this video to power the COB LED, could be used to power a laptop from a 12V DC supply?

  • 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 :)

  • Thanks Matt, clear and easy to understand. I'd love to see your take on electroluminescent lighting and the possibilities. They look really cool

  • 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 !

  • I'd be interested to hear your thoughts on blink stick - effectively a controller board for this kind of project, which has some pretty cool sounding possibilities due to the APIs available in python, node, ruby and a bunch of others. I'd personally love to see a bash implementation but I don't think that's likely to happen as bash on windows is... Meh at best. Anyway, it'd be cool to see projects based on this/just your opinion on it :)

  • Dude got everything The looks The charistma The brain The funding The time My goal is to become these things

  • Hey @DIY Perks, I've been looking around the internet for a wireless charger that can charge through a good bit of wood but haven't found very many with good reviews or that promise a decent charge. It seems like it would be possible to make one that can transmit longer distances than having to have your phone in contact directly with the pad. Might be a good video if interested!

  • 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?

  • 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.

  • 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!

  • You've inspired most of my LED projects, thank you so much for these types of videos!!!

  • 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!

  • 13:38 Those strips of leds should be in parallel if they are longer and your use case allows. The reasoning behind that is voltage drop. The longer the led strip the more voltage drop you get and the leds will become dimmer the further they are from the power source. The setup pictured by no means requires that, but it's good to know.

  • Hi Matt, big fan of your channel!! You have inspired me to do lots of small projects during the pandemic time. I have one question and request, would it be possible to build a lightweight portable powered LED light with velcro straps on to my helmet while skating safely at night? Would love to see a tutorial video on this. Cheers, and stay safe.

  • 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.

  • 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!

  • This is the man who inspired me to buy a soldering iron. And I must say, it's really worth it, the amount of fun and useful projects you can build with junk electronics and parts is insane!

  • Great video! I was experimenting about month ago to build my own rgb cw ww light for photography and video that could be powered from power bank. I bought aluminum profile 4cm wide for led strip with white milky cover for it. I was able to stick inside 3-1m long led strips where was 60 led ‘s per 1m. Controler was instaled also inside of this profile and i solder each strip together. From one side I have cable going out from that profile with usb A on the end where I can connect power bank. This light support all spectrums of white and also all colours from rgb.I was able to run this light from power bank for about 20 min and then I could use only some colours or it did not work properly. After testing I find out that there is only few colours I can create from rgb and it is bit limited and light is not as bright as I would wish. Could you please build some RGB stick light that can be powered from battery and it will have also white cold and warm and it will be bright enough that could be used for video and photography? there is lots of lights that can be purchased for about £100 with remote controller and battery but I would like to build something custom that can be long as 1m and can be used in many different situations.I have done some search but I haven’t found anyone who done this before only with white light and they are changing colour films to change colour which is not the best option. I’m sure there is too many videographers and photographers who would love to have this kind of light in their arsenal :)

  • As a videographer who would be wildly interested in designing my own LED lights, and wondering if you can drastically reduce cost that lighting companies like Aputure, or Arri charge for their professional lights. I am curious if the price difference is enough to make it worth it to try and make something you could use on set. I am also curious if you could make them bi-color and switch between the temperatures, dimmable, and how one might go about making a controller to access all of the RGB colors. If you made a course for this I would pay for it, absolutely. Thanks for this info! What was your cost breakdown for this light you made?

  • 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!!

  • Fabulous, really easily understood explanations. I now understand about 'constant current' for the first time!! Keep these coming please. Good work.

  • Bardzo dobrze wyjaśniony proces pracy LED. Super lampka.

  • More videos like this please! Great explanations for beginners and fun to listen to for someone more advanced too.

  • Thanks for all the useful information. I’m trying to put together a solar powered LED to mount into my old gas lamp post, and would love to hear your take on how to make this work with a solar panel and rechargeable battery.

  • Thank you for making this video. So easy to understand the leds. Can't wait to make my own with your instructions.

  • Since I saw the fake window lights I've been considering to make some myself. It's a brilliant thing for basements. But it's quite a scary project to start on. Without any knowledge about LED and currents. This helped allot with the understanding around LED's and made the idea I have for my basement not that scary to set to life. Thanks allot for these informative videos.

  • This was absurdly amazing. Seriously, this is one of the very best channels on YT

  • Matt, I appreciate your clarity in explaining this build. Could you pls tell us how long that LED light can be powered from a 20k mAh bank at full charge, and the costs. Thanks in advance

  • Great video as always! The explanatory content about LEDs is just fantastic.

  • Excellent video! This covered all of the information I was looking for and some that I didn’t even know I needed. Thank you!

  • 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

  • If my physics teacher cared even 30% as much you do, i'd be a damn scientist by now.

    • @TheGalacticWest They never teach you the cool stuff in school, you have to find the ILaward geeks to have the real fun!

    • @TheGalacticWest I’m a kid and I think they’re cool.

    • They dont ever teach you the cool stuff. Then again i didn't think LED's were cool until i was an adult.

  • I just love your videos. They are quite professional and you explain things really well and accurately. Thanks for sharing! 😀

  • Thank you for this video Matt!! I start to understand the LED lighting better. I want more videos like this! Thanks!

  • 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

  • Hey Matt, I just re-watched this. Great video. I would love to see a video the explores optics and how to get a great throw out of an led light. Thanks. :D

  • Your videos are simply amazing and I've learned so much from them - and even more importantly, they inspire me to do more. Thanks a bunch! Well, that's my take. My wife hates you. We now have multiple gadgets and I have commandeered multiple tables for these.

  • There are also COB modules that include driver chips that enables the module to be powered directly from mains AC power.

  • It's actually fairly easy to calculate the minimum level of cooling needed, from the watt to be dissipated, the max temperature the LED tolerates and the thermal resistance in each part - then it doesn't have to be trial and error. I know this is DIY but a bit of math never hurts anyone.

  • Hey Mat, nice deep dive on the electro-chemistry of LEDs! -Ken

  • Great video. all your videos are very well thought off and structured for easy comprehension. If you can, please start a tutorial series on electronics. Great work by the way!

  • I would like to see you and great Scott to have a collaboration together it would be great to see your creativity and well throughout designs and ideas and his extensive knowledge of electronics put together

  • Please do a video explaining different methods of controlling addressable RGB LED strips. You always explain things so well!

  • Hello, you have made great work on this video! My question is if I can create a little headlight and put it inside my PC case for directed lighting... I concerned about the temperature of leds, so if you have the solutions it would be very helpful to listen your propose... Thank you!

  • 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.

    • Seems like MacGaver with extra steps

    • 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.

    • MattGyver.

    • You mean MacGyver?

  • 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

  • This is an incredible modular type tutorial, more please!

  • Wonderful ! I need to add LED grow lights to a preexistent system but I didn't want to buy a complex and industrially made lamp. As I've been watching your videos for a long time I knew I could do better (and cheaper !) than that. I think it's time I buy a soldering iron ! :D

  • 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

  • "A big long standing project i have planned is mimicking the sun" Say no more *few weeks later* New Video: How to harness the power of your DIY sun

    • Well the Chinese are really have built an artificial sun... in a few decades there would be DYI and light that dark corner of the galaxy you are living on... yeah I know too much Mass Effect ;)

    • And then: Making a DIY Dyson Sphere for my DIY sun.

    • Being able to accurately mimic the sun's output would make it possible to have near perfect health even in doors, underground, or in absolute dark night conditions.

    • May be how to power the diy sun with itself 😂👍

    • Well.. you weren't wrong

  • Very good introduction into LED tech. Note however there might be laws in place in some countries concerning attaching such lights to your bike and participation in traffic (for your safety and that of others).

  • Well! You just gave me enough information to turn me into an infrared blasting monster! My huge backyard is pitch black at night as it will stay because of camera-shy neighbors. Now they can stay shy while I can see my whole domain without them seeing a thing. I figure I'll be needing several hundred watts. I'm gonna have fun fun fun until daddy takes the soldering iron away . . . Thanks again and again and again DIY Perks!

  • 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.

  • I will watch anything that this guy uploads. Such a calming and intruiging vibe this man creates. Great video as usual!

  • Every single video here ,not even one fail to remind me this channel is totally worth the subscribe and notification.

  • Matt, would you consider making a video about how you work with aluminium? I'd happily see some summary of your experience, especially since I recently saw the aluminium case for PC. I even laughed a bit when you said in the video, that you liked working with aluminium and planned more projects with it. I'd like to build something like a "server" case for my old laptop motherboard (which has fired integrated GPU anyway) with passive cooling. Unfortunately, I lack both experiences with the material and space to do it so I am looking for a cheap, home methods I could use in flat in the city. I think the same can go for pretty much any material, as working with wood would be as interesting (although maybe less useful for my server-laptop) use case

  • 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!

  • This is great, thank you for making it - going to try this over the winter myself 👌

  • Brilliant as ALWAYS = I'm always inspired to build something after watching your videos. Maybe one day I actually WILL!! Thanks as always for sharing.

  • 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.

    • I think he's referring to the color rendering index rather than the parallel ness of the light beams there.

    • duffahtolla I actually tried linking to another video of it in my first comment but the Coelux (Italian?) company had a nice looking light back in 2014 that had these various angles for latitudes.

    • 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/

    • @Justin Janes Carbon Nanotubes :)

    • Take it up a notch - lets consider condensed gas with ratios similar to atmos into a gel coating that mimics blues.

  • Hi Matt, I know you're most likely working on a load of exciting other projects right now, but I came here looking for a COB LED for video and was sure I saw you had made one in the past (was I mistaken?) , Suffice to say, I love your panel designs but would love to see a decent COB for video light project! If anyone else reading can point me in that direction I'd love to see it! Many thanks!

  • hi matt. glad to have followed your videos for a while now. I have made 9 3d printed lamps with 5w, 9v led's and supplied it with a 24v 30W zigbee (IKEA) power supply connecting 3 led's in series. each LED gets 8 volts. but the light is too low, and all 9 volts sadly melt the 3d print. I found the sweet spot is 8,5v. so now I am on the hunt for somehow to get 8,5v 17v 25,5v 34v I like the fact that the power supply is zigbee controlled so I can control the light with my hue setup. I have tried to add a PWM to the setup but it seems the zigbee power supply doesn't support the PWM. Do you have any recommendations on how to achive 8,5v with still supporting zigbee ? I am honestly a bit lost. I have put many hours into building and designing it and I would be sad to just see it become a "mood light" in a corner. - I was hoping for a dinning table lamp. keep up the great work love seeing your builds!

  • I didn’t understand much of it, yet was certain it was being explained perfectly. This isn’t even an area of interest for me yet I loved the video, just goes to show how fantastic this guy is.

  • Please keep creating more projects if you are free. Your projects inspire many people like us and keeps entertained during these times. Thank you!❤️

  • Perkz: Just look at all that light (points light to me) Me: 😵😵😵

    • @Ichan Komo why have led eyes when you can ghost in the shell camera eyes?

    • Now u'll need led eyes

    • lol

  • Thank you, Matt, I thoroughly enjoyed this. I have always been a fan of LED'S and use the LED strip lights for making signs. You gave an interesting picture of the capabilities for uses of LED'S. Thanks for sharing and teaching. Felix
