Who Invented The Light Bulb?

In 2018 the LED lighting market was worth almost $52 billion and is expected to reach over $112 billion by 2024. But 200 years before LEDs were a multibillion-dollar industry, and decades before Edison showed up, light bulbs were an idea just starting to enter the minds of curious scientists.
They may look the same, but the lights of today are almost nothing like those of yesterday. Watch the video to find out more about the transformation of the light bulb.

[@ZoNy718]

did we forget my old friend the black light? "William H. Byler is credited with inventing the black light in 1935, and according to the University of Central Missouri, Byler graduated there in 1927 with a major in chemistry and physics. A black light works by producing UVA light, or ultraviolet light, that we cannot see."

[@jjw238]

More importantly, if the lightbulb was not invented yet, what appeared on top of Edison’s head when he had an idea?

I remember when my grandfather started to build kits to convert early blue LED's to regular light bulb sockets in clusters. He finished the first prototype in 2008 and he still uses that bulb. He wasn't a very smart business man so he mainly did this for his own personal usage.

Instead of trying to steal history try and promote something that black skinned people actually did invent, like Lonnie Johnson who invented the super soaker water pistol.

Joseph Swan was using carbon filaments back in 1850, with a patent granted back in 1860 using such a filament in a partial vacuum. He had a work, demonstrated carbon filament lamp in February 1879 to an audience of 700 and obtained a patent for that in 1880. In 1880, he gave a lecture illuminated by his electric light, be first public room to do so. Swann's house, Underhill, was the first domestic building to be illuminated by incandescent light. In short, whilst the competition was close, Swann go there first.

Go Newcastle, except he was from Sunderland and lived in Gateshead where he did his most of his experimentation on the light bulb. Although he was a partner at a chemical company in Newcastle.

[@dragonskunkstudio7582]

13:33 Incorrect statement Painting is different that lighting, painting is a subscrative process, meaning from white you apply color to take away hues, combining cyan, yellow, magenta, etc. where lighting is additive combining colors to make a hue using red green and blue.

[@joesterling4299]

I thought he was going to say like television; but he went for painting instead. Oh well. The meaning is still clear.

[@stevebarlow1341]

You’re correct. The typical white LED

[@stevebarlow1341]

Typical white LED for indoor lighting uses a blue pump and then red and green phosphor to create different white color temperatures. The green has some yellow primary spectrum.

The Next Step..., How do we come to the realization that some level of darkness at nighttime is required for the health & well-being of human beings as well as wildlife ?? The LAST thing that we need outdoors at night is ARTIFICIAL Blue Light Wavelengths. It messes with our Natural Night Vision as well as our Circadian Rhythms. We need to be mindful of how Over-Illumination could negatively impact the natural world that we depend so much on. We need to Shield our Outdoor lighting to avoid causing Light Trespass, Light Spillage & Light Pollution..., Shield it so that you don't see the light source, only the light produced. We need to use "warmer" color temperatures(Kelvin/CCT/SPD) of never more than 2700K. We need to use ONLY the intensity of light that we need Not, overdo it. And when no one's around to need the light, we need to shut it off. We must also realize that excessive lighting does absolutely Nothing to deter crime. If that were the case then, there would be nearly Zero crime during daylight hours and gas stations would be amongst the Safest places on earth(and we all know from watching the news that, that Isn't the case).

[@AverytheCubanAmerican]

I’ve been to Edison’s lab in West Orange as well as Menlo Park (now Edison, NJ). It was cool to walk on Christie Street, the first street in the world to be lit by incandescent light bulbs

[@thetreehousestudi0]

With all due respect to those who put this together. You should also add in Edison partner Lewis Howard Latimer who not only improved Edison invention but he was the one who actually helped him patan the carbon filament. He came up with the idea to add a carbon filament to the light bulb to last more then 4 days. It is important that all fellow contractors to the evolution of light be high lighed. Lewis Latimer helped a lot of people back improving inventions and his own as well as helping people patan their ideas. He should be recognized. GE wouldn't be what it is today with out his investment. Highlight Lewis Howard Latimer! @cnbc

I wish they would have talked about halogen light bulbs; a close cousin to incandescent bulbs but that's it's own type of light bulb with it's own characteristics and qualities. For many they are also seen as the best of both worlds consuming a little bit less energy than classic incandescents for the same amount of light yet having all the qualities we like of incandescent bulbs and none of the disadvantages that comes with fluorecents and LED and producing one of the most pleasant colour temperature for artificial lighting only slightly whiter than incandescents.

[@DaEmperah]

No mention of Lewis Howard Latimer , shame on CNBC

[@wildman8200]

Just like the telephone and a few others, the light bulb was invented in Canada. The telephone was invented and built in Canada but the patent was filed in the United States. The light bulb had many first iterations, but the light bulb we know today came from the designs of Canadians Henry Woodward and Matthew Evans. They sold their design to Edison who then used his expertise to create a functioning model.

[@StarFleet_Tech1701]

wild man Those products were built in America by Canadian people. Basketball and the Telephone were conceived in USA. The people who did it were born in Canada. Credit of product creation begins in location it was done not where the person was born. By your logic, all Apple iPhones, iPads and other i-Products were built in Syria. This is because Steve Jobs was born in Syria. However, that is not true. Mr. Jobs created those concepts and products in the USA so those products are credited as being initially products of the USA.

[@wildman8200]

@@StarFleet_Tech1701i fixed my statement regarding basketball, always thought it was invented here but it was in Springfield Mass. On another point Bell himself said the telephone was invented in Canada during his time off for summer vacation. He lived in Boston during the school year and Ontario during the winter and summer. The invention came to fruition in the Summer of 1874 in Ontario, he would later file for patents and make the product in America. www.collectionscanada.gc.ca/innovations/023020-3020-e.html www.google.com/amp/s/culturemagazin.com/the-telephone-an-invention-in-canada-that-changed-the-world/amp/

[@darkshadowsx5949]

right? green isn't even a primary color. it works with light but not paint.

[@1N73RC3P7OR]

@@darkshadowsx5949 I hate to tell you this but cyan and magenta also aren't primary colours.

[@TheEulerID]

@@darkshadowsx5949 Green is a primary colour as it's one of the three colour receptors in the human eye (the other being red and blue). That's why screens are described as RGB. What painters might call primary colours are no such thing. That's because paint is subtractive, not additive. It can only filter out a colour, it can't create them. Hence the colours in a simple inkjet printer are cyan, magenta and yellow. Cyan ink filters out the red leaving green & blue, magenta filters out green leaving red & blue and yellow filters out blue leaving red & green. Hence mix yellow and magenta and only green remains. In real life, it's not so simple in that the eye's colour receptors are not tuned to one wavelength of light. Instead the three have overlapping curves of sensitivity against wavelengths. Also, pigments are not pure either. However, in the big picture that's the way it works. Paints/pigments are subtractive and they do not have true primaries.

The thing is... the LED lighting elements _themselves_ are designed to last a long time... but in many bulbs, the electronics in the base will die first. Same thing with CFLs-I don't think I ever had one last more than about two years, regardless of brand, before the electronic ballast in the bulb's base failed, not because the tube itself wore out or otherwise failed.

Lewis Howard Latimer In 1882, he received a patent for inventing improvements to the Process of Manufacturing Carbons 252386 for light bulbs. His idea was to protect the filaments in a cardboard envelope preventing the carbon from breaking or changing shape during the intense lighting process. The significance of these improvements allowed for a reduction in time to produce and an increase in quality, his process set the standard for over 20 years. In 2006, he was inducted into the National Inventors Hall of Fame for his Process of Manufacturing Carbons. Mr. Latimer was issued 7 U.S. patents.
