Light Bulbs and Artificial Lighting
Artificial lighting has become standard in the homes and companies of most countries. It is used for concert effects, growing food, and reading a book in bed at night.

How do you fix a blown light bulb?
After worrying about being the butt of many light bulb jokes and sifting through all those who thought a pot light would help them grow their habit at home, I ended up calling a guy who has a business called "Mr. Potlight". In the end, changing the pot light was easy, once you know how.
Here's what you do:
1. Pull out the whole can that houses the light (the 'can' is the term used for the cylinder that surrounds the light). This is the hardest step because we are not used to taking out the whole light fixture when changing normal lights. Pulling this down takes a little bit of effort and most will be afraid of doing irreparable damage. Grab the outside circular frame and pull downwards away from the ceiling. It should come out fairly easily (don't worry about it falling because the wire attached to the bulb will keep it suspended).
2. Find the plug that attaches to the bulb and detach.
3. Attach the new bulb.
4. Push the entire housing/can back in the ceiling.
5. Turn on the switch. Voila!
When was electric light invented?
Thomas Edison invented the electric light bulb. The first successful test of his invention was in October of 1879, during which the light lasted for over 13 hours. He acquired the patent in 1880.
Why are sodium vapour lamps used as street lights instead of simple white tube lights?
Sodium lighting is more efficient to run than white lights, and it gives an even light with less glare.
What does the filament inside a light bulb do?
when the coil wire in the bulb has electricity passing through it the wire heats up to then create light.
What are the best brands of UV light bulbs?
The best UV light bulbs are made by Sylvania and Philips. The downside of the story is that UV light bulbs of those brands are among the most expensive on the market.
UV lamp, also called Black-light Lamp, device for producing electromagnetic radiations in the wavelengths between those of visible light and X-rays. The Sun's rays are rich in such radiation, sometimes referred to as black light because it is not visible to the unaided eye.
How did Edison solve light bulb problem?
Edison's problem was DC. You would need a generator every few miles. He didn't solve the problem Tesla solved it. AC was a better system.
Who was the first person to invent the light bulb?
The first incandescent electric light was made in 1800 by Humphry Davy, an English scientist. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. This is called an electric arc.
Much later, in 1860, the English physicist Sir Joseph Wilson Swan (1828-1914) was determined to devise a practical, long-lasting electric light. He found that a carbon paper filament worked well, but burned up quickly. In 1878, he demonstrated his new electric lamps in Newcastle, England.
The inventor Thomas Alva Edison (in the USA) experimented with thousands of different filaments to find just the right materials to glow well and be long-lasting. In 1879, Edison discovered that a carbon filament in an oxygen-free bulb glowed but did not burn up for 40 hours. Edison eventually produced a bulb that could glow for over 1500 hours.
Lewis Howard Latimer (1848-1928) improved the light bulb by inventing a carbon filament (patented in 1881); Latimer was a member of Edison's research team, which was called "Edison's Pioneers." In 1882, Latimer developed and patented a method of manufacturing his carbon filaments.
In 1903, Willis R. Whitney invented a treatment for the filament so that it wouldn't darken the inside of the bulb as it glowed. In 1910, William David Coolidge (1873-1975) invented a tungsten filament which lasted even longer than the older filaments. The incandescent bulb revolutionized the world.

What does the fluorescent light was the sun during the test mean?
it means there was an easy side to the test so basicly it was the highlight of the test
When was incandescent light invented?
The incandescent light bulb was developed in the late 19th century, with significant advancements made by Thomas Edison in 1879. Although several inventors, including Sir Humphry Davy and Joseph Swan, contributed to the technology earlier, Edison's version was the first to be practical for widespread use. His successful demonstration and subsequent commercialization in the 1880s marked the beginning of the era of electric lighting.
How did the light bulb impacted the world?
without it you wouldn't be able to turn on a light whenever you need it. You wouldn't have to use candles ,arc lamps,or deal with no light.
Who produced the first reliable long lasting light bulb?
Thomas Edison was the who pateneted the first light bulb
What are the three main parts of light bulb?
The three main parts of a light bulb are the filament (or light-emitting element), the bulb envelope, and the base. The filament, often made of tungsten, produces light when an electric current passes through it. The bulb envelope, typically made of glass, contains the filament and protects it, while also preventing oxygen from entering. The base connects the bulb to the light fixture and provides electrical contact.
light energy is made by pigs in a power plant and dogs in a air plane. light energy is also made by people living in a pumpkin!
What year did Lewis latimer invent a light bulbs?
Louis Howard Latimer, born in 1848, was an inventor and engineer. However, he did not invent the lightbulb he invented the carbon filament for the light bulb. A part that was patented in 1881.
