Light bulb filament

[PayWithGore]

When into the light bulb placed a vacum the metal would subliment slowly on the glass , that how (in germen we call that edelgas) gas are used, like xenon in car bulbs, right?

[SuperJuero]

Bro... I heard you like coils -Insert Xzibit face-

[poopmyyoutuification]

I thought he used cardboard as the filament

[BroadcastSandwich1]

lets all stop fighting about who invented what and end up with the true answer of the guy who invented everything, Tesla.

[Tanjo3]

On your list of inventors of the lightbulb, you forgot the important Canadian contributor Henry Woodward. Don't ignore Canada!

[XeroK]

This man is awesome.

[theguy51094]

It's the engineer from TF2!

[TheStolenBike]

spy sapping mah lghtbulb

[TheAnimefanatic96]

wow wow wow wow did i read that correctly? 3407 degrees C????? holy cow

[akkudakkupl]

Iridescents have iritating light characteristic. First they dont have the spectrum of incandescents, and they blink at 50Hz (or 60Hz). It kills my eyes and i almost cant see in that type of lighting. 3 phase lighting helps, but still i just like to be stocked on incandescents :-)

[iamchaoticevil]

How come just because Edison patented the light bulb they assume he was the one to invent it. It was Tesla who was working for Edison at the time who really invented it. He was the one that got it working, and even made a different version of it later on as proof he was the one who made it.

[megaexplosions]

tungsten smoke. dont breathe this.

[Choomanama]

wow.....it all makes sense now!!!! thanks!

[Chocobloomsful]

why fill it with argon gas and not any other gas?

[97malthe]

tungsten = heavy stone

[HedgehogStudios1]

hey you are awesome!!! this is why i LOVE science

[cabooses1fan]

yo dawg i heard you like coils...so we put a coil in your coil so you can light while you light.

[TheLEDMusic]

Coilception

[vvhosRoger]

So we saw what happens when tungsten comes into contact with oxygen gas, but what about other gasses? Would the results be any different if you replaced the oxygen gas with helium? Thanks!

[Chnamanjx]

Edison, the Carlos Mencia of inventors.

[commentguy100]

I thought this guy was from team fortress 2

[MrStaxxy]

WE NEED TO GO DEEPER

[irishbboy]

How did they vacuum air out of the bulb back in the days?

[engineerguyvideo]

@irishbboy They had vacuum pumps: Its a pretty old technology .... the hard part, if I recall!, was holding the vacuum in the bulb. Modern materials make this a little easier now.

[irishbboy]

@engineerguyvideo It's just that I've always wondered how they made those noiseless bulbs with the bell inside to demonstrate that sound couldn't travel through void. I mean, sucking air out of a glass bulb would make the difference of pressures massive. I don't know how it doesn't collapse.

[Chileandude18]

@irishbboy it's a sphere of glass...

pressure OUTSIDE the buld pushes inward.... the force is evenly distributed around the sphere...

like a chicken over the egg!

[irishbboy]

@Chileandude18 pressure turns stress forces in the shell into compression forces due to spherical shape, I get you ;) . But still I'm wondering how they vacuum that air out old fashion haha

[engineerguyvideo]

@irishbboy The pressure isn't massive: It is only 1 atm. (Normal atmosphere is 1 atm inside the bulb is essentially zero ... thus a pressure difference of 1 atm.) I used to do work up to 150,000 atms! (Water freezes, for example, at room temperature and about 12,000 atm).

[claude7777]

@engineerguyvideo Is this because the water molecules are getting closer to one another? And does the water expand once it's frozen?

[MrLinuxfanatik]

Whoever you think discovered this principle the fact is, is that it was Sir. Joseph Wilson Swan of Gateshead, Tyne & Wear, England who discovered and developed the Incandescent Light-bulb, not Edison, though after experimenting with what Swan had discovered developed the light bulb further and, in 1883, Edison and Swan joined forces and became the lighting company Ediswan. linuxfanatik

[dkash0121]

@irishbboy how do they do it now?

[DonCramon]

Edison stole the idea from Nikola Tesla. Tesla developed and used florescent bulbs in his lab some 40 years before industry "invented" them. At the World's Fair, Tesla took glass tubes and bent them into famous scientists' names- the first neon signs. + many other inventions such as: radio, X-rays, vacuum tube amp, florescent bulb, neon lights, speedometer, auto ignition system, and the basics behind radar, the electron microscope, and the microwave oven... just to name a few. Look it up..

[WOGI5M]

I always wanted to know a lightbulb works! thanks man, your videos are awesome!

[humbabaa]

we need to coil deeper!



[Kulopto]

I was told that Edison created a better filament. Someone else created the lightbulb.

[DonCramon]

@Kulopto Yes Nikola Tesla did. Search in google: "Tesla versus Edison" or "Nikola Tesla light bulb"... Tesla is the man behind the most amazing inventions.. People just stole from him. And Edison was the worst of them..

[CraigMerton]

I didn't know that producing the filament would be such a complicated process. There is one type of bulb that I find particularly interesting and it is the halogen bulb. I used to wonder what it is that makes it brighter and whiter than the regular bulb. What I found is that the halogen gas in the bulb makes it possible for the filament to endure a higher temperature without evaporating.

[CraigMerton]

@CraigMerton The gas in a halogen bulb reacts with the evaporated metal as soon as it leaves the filament. When the metal-halogen gas touches the glowing filament, the heat from it breaks the molecule and deposits the metal back on the filament.

[CraigMerton]

@CraigMerton The gas pressure and the glow temperature is carefully calibrated so that this halogen cycle of depositing metal on the filament is at its peak efficiency. If you feed the bulb with too high a voltage, the gas will not be able to receive all evaporated metal. If you feed it too low, the cycle will not be complete. That's why it is good to periodically run dimmed halogen lights at nominal voltage so that the halogen cycle can fully deposit metal back on the filament.

[CraigMerton]

@CraigMerton

Also note that low voltage (12V) halogen bulbs have a considerably thicker filament than high voltage bulbs and they glow at a higher temperature which is why they have a whiter light than high voltage halogen bulbs that have come to the market recently.

[CraigMerton]

@CraigMerton I also heard that if you touch the bulb so that grease or dirt is left on the glass. The light will heat it and the heat will make the glass crystallize. When the glass crystallizes it will no longer be able to seal the gas since the crystal form is not gas tight which the amorph glass is.

[CraigMerton]

@CraigMerton Lighting technology is interesting and I've learned quite a bit about fluorescent lights. I used to wonder why they use noble gases in incandescent tubes. It turned out that this gas is uesd because it doesn't react with the electrodes even though electricity is flowing through it.

[CraigMerton]

A rather new invention is the sulphur lamp or daylight lamp which is an incandescent lamp. What's remarkable about this lamp is that its light spectrum is very close to the black-body spectrum of sunlight. It is said that this is due to the diatomic nature of the gas (S_2).

[CraigMerton]

The sulphur is sealed inside a quartz crystal and there are no electrodes as the sulphur would corrode them in no time. Instead the sulphur is heated by a magnetron that heats the sulphur inside the ball using microwaves, very much like a microwave oven. When the sulphur is turned into a gas (or plasma) the microwaves excites the molecules and make them glow.

a coil within a coil??thats coilception!

[thejollycheezcompany]

IM BRITISH IAND I BELIVE EDISON INVENTED THE LIGHTBULB

[engineerguyvideo]

@thejollycheezcompany Assigning the invention of something is more difficult that most people think. We're working on a companion volume that will include the topics in this video, and I'll discuss there who exactly invented the light bulb. As you can guess there isn't a completely clear answer. Who commercialized most successfully? Well .. Edison and Swan!

[limeroundup]

A coil within a coil? We need to go deeper!

[KellytheeAwesome]

what happens if theres a crack in the lightbulb and oxygen gets in?

[engineerguyvideo]

@KellytheeAwesome It flames out about like what you saw when I turned to bulb on without the glass enclosure. In the first bulbs one of the trickiest aspect was getting a good metal-glass seal.

So the guy that invented the coiled coil of tungsten reach to its final design by pure empirical knowledge?

[engineerguyvideo]

@CamiloSanchez1979 Kind of ...he had observed how other metals behaved .... crunch gear linked to the original paper ... it makes interesting reading.

[Chasetherat2000]

oh no he did not just steal from Bill Nye the science guy by calling himself the engineer guy!

[engineerguyvideo]

@Chasetherat2000 I think Bill Nye actually was trained as a mechanical engineer!
