I mean it lowers the life span of the bulb but since it was already broken it isn't that bad. The missing led in the circuit will make the other leds shine brighter and it will lower their life span.
Graphite has high electrical resistance, meaning it heats up when an electric current is applied to it. I've made mechanical pencil leads glow red hot from 12V batteries, and you're dealing with actual grid power here.

Sorry but any insurance will not cover self-made stupidity. Naturally one could be silent when something happens but that would be an insurance fraud. If a led has already failed this most likely means these leds are driven to their limits. Taking one out with graphite resistance does not give much hope for the rest of those leds.

1. most LEDs have some kind of tolerance so they won't instantly burn out if you remove one. unless it is one of those vintage lightbulbs where are like 4 diodes, you will be fine. 2. if they, as you say, burn out, the power will be instantly cut, due to circuit disconnecting and no it won't set your carpet on fire, because there is this plastic casing that covers it (unless you are lazy and don't put it back) so don't worry, your lightbulb won't instantly explode if you remove one diode from it.

If one led opens circuit and the rest folliow, that means it is ‘series’ connected (not parallel). If you jump that, the rest will work again but NOW become overvoltaged and therefore overloaded.

@@liboy9844Good point :-) LEDs will burn out, but not in the way you might think, they won't just randomly catch on fire or explode, they will burn from the INSIDE, so by the time they would start overheating, they would already be burnt out and the circuit disconnected so it would just stopped working (again). ultimately you should just solder in some other LED or Resistor using a soldering iron and NOT A FUCKING PENCIL, (Or you could buy a new lightbulb, but cool engineers don't do that, am I right?)
@@Tyvototuo Yep, good point there. However, let’s not forget that the risk is not only in the bulb or appliance per se but also on the wiring and contact surfaces (eg plugs receptacles and switches) suporting the equipment.

Learned this from actual experience that’s why I’m extra careful these days at risk of not being a ‘cool’ engr. anymore. Cheers bro 😃.
It won't last long. Because the electric power generated by the components will remain the same. While the electric power received by the lamp will increase because there is one lamp that does not consume electricity as it should. And other lights will experience an increase in temperature making it easier to get damaged.
Not necessarily! The pencil carbon graphite has a small resistance to it. I've never measured that small of a line but it should be enough to Limit the current through it.
It depends on the type of power supply. If it is a current source then the current will remain constant if LEDs are removed from the circuit. If it's a voltage source, then the voltage remains constant across the entire string of series connected LEDs, and if an LED is removed, then the voltage across each of the the remaining LED's will increase, causing the current through the LED to increase which might exceed the maximum current permitted for the individual LED, leading to a reduced life or instant burn-out. The correct way to drive an LED is with a current source. However, voltage sources are also used.
@@samueladitya1729 That's true only if a current source is used. We don't know in this case. It could be a simple voltage source with a series resistor to set the current.

You're confusing the old type of LED which contained a voltage converter, to the new filament LEDs which only contain a rectifier and some capacitors and probabbly a linear regulator
Great job. This only works when all bulbs are connect in series ( where each bulb depends on each other) so when one has a fault they all can't light. That's why he used jumping cable on every bulb and when he reached the faulty one , the blocked current jumped through the cable to complete the circuit so that's what made all the rest bulbs to light when the cable was on the faulty bulb.

@@Maks905 Да, вы правы. Я что-то затупил. Диоды же питаются от источника тока, а не напряжения, благодаря драйверу (даже примитивному). Хотя можно встретить крайне примитивные драйвера, которые не стабилизируют ток (по сути являются источником напряжения), тогда остальные диоды начинают светить немного ярче, но недолго.
if you were paying attention in your physics class, you would know that once an LED "breaks" it instantly cuts the circuit, thus eliminating the chance of a fire.
How safe is this? Like genuinely. I know people on here saying how cheap it is to buy a new one or this being a fire hazard. But I mean if you can safely re-use/fix the led bulbs you already have then that’s awesome.
It shows that the LED’s are serially connected. When it’s serial connection one fused will not let current pass. Then to let it pass graphite power from pencil which is a conductor is used. Smart idea.
People talking about fire hazard, which not true, first those circuits have a current limited regulator to not damage the LEDs. The issue here is it's a waist of time and efforts, all LEDs at end of life phase, they will not finish all at once, but they gonna start falling one by one, in matters of days, then what you gonna keep fixing like this everytime? The only solution is to replace all LEDs which will cost more than that bulb(time and money), so just buy a new one.

Individually yes but…….they are floating at the mains voltage!!! And graphite is a fabulous resistor!!
Bad idea
@@brendancooney9401 No they are not the LEDs are powered by a power supply which supplies a lower Voltage. Only Filament LEDs are directly powered by mains.
@@jjjannes no, most LED bulbs are floating at mains voltages. Individually they see only low voltage but they are floating at mains voltage above ground. A very efficient and most importantly very cheap way of manufacturing them.
@@brendancooney9401 Not this type of LED Lamp, there are about 16 LEDs, over each LED there is a voltage drop of about 3,3V. This means that the voltage connected to the LEDs in series must be about 50V not 110V.
You're confusing the old type of LED which contained a voltage converter, to the new filament LEDs which only contain a rectifier and some capacitors and probabbly a linear regulator
Better to replace the damage smd led
Another amazing tip for saving you a little penny.... Don't do this, just buy a new god dang lightbulb
man I love wait do y’all smell something burning
Great job. This only works when all bulbs are connect in series ( where each bulb depends on each other) so when one has a fault they all can't light. That's why he used jumping cable on every bulb and when he reached the faulty one , the blocked current jumped through the cable to complete the circuit so that's what made all the rest bulbs to light when the cable was on the faulty bulb.
If you want to fix a lamp like that, at least use a soldered bridge
It wont Light long, the other LEDs get to much power and will burn quick.
Проще паяльником снять светодиод и запаять контакты.
А ещё проще не мучать себя и лампочку, выкинуть её и купить новую
火事になる可能性が高くなりましたよ！
ничего не загорать, нечему в лампочке гореть...

Только от карандаша, гореть не будет, нужно удалить сгоревшей диод и спать два контакта, если прочно.
А так можно приклеить фольгу скотчем.

А ели есть деньги - просто покупаешь новую лампочку и маешься дурью с перегоревшими диодами.
How to cause a fire 101
Coming from someone that doesnt know anything himslef
@@creativetech215 lol what
@@BenCos2018 is that gonna cause fire?
@@creativetech215 yes.....
mains combined with failing leds
also it means the other leds have to deal with extra voltage so the circuit is running higher than the voltage they are designed for
It's a bad idea also considering a new bulb is max about 6 euro
Lots of spoiled people making stupid comments. That’s actually pretty clever and will solve the problem in many 3rd world countries that can’t afford to throw away and buy new stuff so they do it out necessity.

Q: how to fix a burnt out lightbulb
A: don’t
wow 😲 creativity idea 💡
It's usually NOT the LED that's bad. It's in the circuit board underneath.
Yep but it worked
Раньше гирлянды были с лампочками накаливания. И вот соседка-одноклассница посмотрела по телевизору лайфхак, что если гирлянда не горит, то нужно сгоревшую лампочку завернуть обернув сначало в фольгу. Она чинила так, пока чуть-ли не половину ламп так не закоротила. Как у них ёлка не загорелась😂
Only people with no clue about electricity or those who are in these light bulbs who are posting negative comments.
Some people are telling it unsafe, but it is safe, being an electronics engineer, pencil tip is made of lead, which is conductive material, using pencil will solve the problem around 70%, as it is bad conductor, but bulb will glow and can work in low light, so don't try to be a non informative scientist, and know the technicality.
nice bridge... take a thermal video of it and then deside if you wanna burn down the house!
Good Video man, next Time one of my LED bulbs goes, I’m gonna take it apart and try to fix it and save a fiver, Thanks for sharing 😁👊
watch your house burn down from doing it too 😭
Just in case you're not joking. don't do this.
Back in my day you just unscrewed the old and screwed in a new one
still do. this is just one of those nobody knows this is bullshit so theyll all think its clever type videos.
I’d prefer my continuity tester and a soldering iron
Use a bridge to verify the dead diode, but use your captain obvious peepers to find the dead diode by the massive escaped smoke stain around it.
That’s just where the magic came out
😅
После такого ремонта повышается ток на остальных диодах, следующий перегорит очень скоро, а следующий уже, возможно, через несколько минут.
Если установлен драйвер, все будет норм, он понизит ток . Но все же его нужно подрегулировать чтоб не сгорали больше диоды .
@@everythingabout6066 не понизит, он знать не знает сколько диодов работают. Регулировка в таких лампочках не предусмотрена, только перепайка.
ток не повышается, а перегорит скоро это да, ведь остальные светодиоды тоже деградировали уже
@@Maks905 Да, вы правы. Я что-то затупил. Диоды же питаются от источника тока, а не напряжения, благодаря драйверу (даже примитивному). Хотя можно встретить крайне примитивные драйвера, которые не стабилизируют ток (по сути являются источником напряжения), тогда остальные диоды начинают светить немного ярче, но недолго.
Графит от карандаша гасит ток
Убрав один светодиод для остальных ток будет повышенный что приведет к сгоранию следующего светодиода
Если стоит хороший драйвер, то ток останется прежним. Но всё равно много диодов нельзя закорачивать)
Thank you RUclips . Today my daughter told me that bathroom bulb is not working . And in response you send me this video .

Never take risk, nor do this.. just buy or replace for a new one, it's more safety!!
🤩👍
If you want a light as dim as you are. Then buy it that way from the start.
Apparently this went right over your head.
@@JosephQPublic So what you buy things then break them so they do something other then what you bought them for? Okay you have fun with that.

Alternative tittle: how to set your house on fire
Bro you are not good at electronics
if you were paying attention in your physics class, you would know that once an LED "breaks" it instantly cuts the circuit, thus eliminating the chance of a fire.
👍
How safe is this? Like genuinely. I know people on here saying how cheap it is to buy a new one or this being a fire hazard. But I mean if you can safely re-use/fix the led bulbs you already have then that’s awesome.
It shows that the LED’s are serially connected. When it’s serial connection one fused will not let current pass. Then to let it pass graphite power from pencil which is a conductor is used. Smart idea.
新 品 買 え

Tokone wis tutup...😂
What resistor should one place when by passing one led, if it's not done the others will be brighter and burn faster
It works but unfortunately brightness is only 10% so better is to remove the yellow led
life hack how to lose 90 percent of the brightness of a light bulb
Better than the other „how to fix“ videos in which the LEDs were bridged with tin foil. At least by this they will not burn out faster.
Maybe he sells it or takes it back .. Mine is loose and falling apart . Hmm
This is why housefires is a thing
People talking about fire hazard, which not true, first those circuits have a current limited regulator to not damage the LEDs.
The issue here is it's a waist of time and efforts, all LEDs at end of life phase, they will not finish all at once, but they gonna start falling one by one, in matters of days, then what you gonna keep fixing like this everytime? The only solution is to replace all LEDs which will cost more than that bulb(time and money), so just buy a new one.
Why is everyone saying it'll be on fire?? I see this a a way to actually save money!.

Végre valaki leírta, hogy a LED-eket áramgenerátorosan hajtják meg. Ha egyet rövidre zársz, attól még nem nő meg az átfolyó áram.
Ну его же и так видно было :)
Графит хороший проводник, но:
- при прохождении тока он начнет нагреваться;
- оставшиеся светодиоды начнут греться больше нормы для них из-за увеличения проходящего тока и как минимум, проработают недолго;
- такой ремонт может закончиться и пожаром.
If I remove the broken led and replace it with a new one, will it work normally?
It should , unless the buck is crazy
Before doing this Job call to fire station 😂😂😂😂
no resistors added?
Тогда уж лучше выпаять светодиод, и вместо него припаять резистор со схожим сопротивлением

I used to think its worth less.. Now i can use pencil wisely
Graphite is good conductor of electricity
