What are the facts about a light bulb?
- A light bulb is a device used to create light (illumination).
- A light bulb is also known as an incandescent light bulb, incandescent lamp or an incandescent light globe.
- A light bulb uses electricity to heat a wire filament in an enclosed glass case to produce light.
- The incandescent light bulb contains a base, glass enclosure and a filament.
Apr 11, 2018 · The British experimented with electric light beginning in 1835 by creating the arc lamp, but it would be another 45 years before Edison patented the first incandescent light bulb in 1880 after much trial and error. Along with electricity, the light bulb paved the way for cleaner and safer ways to use artificial light in darkened homes at night.
Lewis Latimer was an inventor and a scientist who helped develop the electric light bulb. He was also an artist and an expert on the laws that cover inventions . Lewis Howard Latimer was born on September 4, 1848, in Chelsea, Massachusetts, to freedom seekers who had found a home in Massachusetts.

A Brief History
The electric light bulb is one of the everyday objects that we rarely pay attention to, even though it has a complex history. It is thought that Thomas Edison invented the first light bulb in 1879, though scientists and inventors had been exploring how to invent incandescent light bulbs for several decades before Edison.
What is Incandescent Light?
The first light bulbs were all "incandescent" light bulbs, meaning they were created using a glass bulb or lamp which had all the air sucked out of it to create a vacuum (a space with very little or no air) and in this glass bulb there has to be a very thin piece of metal (also known as a filament) held by an electrical circuit. The wire is heated up and starts to glow to create light. Connect your History lessons and your Science lessons by matching resources like our Sources of Light PowerP...
As far back as 1802, a scientist named Humphry Davy from Englandinvented a simple electric light. He experimented with electricity and created a circuit with a small battery. When he connected wires to his battery with a piece of carbon between the wires, the carbon glowed. This circuit became known as the Electric Arc Lamp, but it burned too brigh...
In the several decades that followed Davy's attempt at creating the first light bulb, other inventors also had a go at creating light bulbs, but unfortunately none of their designs were able to overcome all the problems that Humphry Davy first noticed. These attempts sometimes muddy the water when answering the question of “who invented the first l...
One of the major problems hindering the progress of the invention of the light bulb was the cost. The early light bulbs were expensive to make, and therefore not practical for commercial use. Joseph Swan took it upon himself to tackle this issue of cost. The English chemist did so by using carbonised paper filaments instead of platinum filaments in...
So, what is it that gave Edison the edge over his competitors in becoming the first person to invent the light bulb? The key was in the practicality of his design. Edison had managed to invent a light bulb that was inexpensive and practical, making it ideal for commercial use. This didn’t come to him immediately, however, as Edison is reported to h...
1845 - John W. Starr patents incandescent light bulb with carbon filaments.1850- Joseph Swan begins work on light bulb.1860- Swan patents a partial vacuum, carbon filament incandescent lamp.1872- Alexander Lodygin patents an incandescent light bulb with tungsten filaments.Unfortunately, incandescent light bulbs are very inefficient - only about 10% of the electricity is turned into light, the rest is lost to heat. Though, because they are easy and cheap to manufacture, incandescent bulbs are still widely used today. Although, with the advent of the first LED light bulbs, there has been more legislation from world go...
The electric light bulb is often credited as being the most important invention since man discovered fire! It completely transformed society. People were able to stay up longer, the work day was extended, socialising in the cities after dark became more popular, and homes became safer as they no longer relied on fire for light. The light bulb also ...
Nov 22, 2013 · In the 19th century, two Germans -- glassblower Heinrich Geissler and physician Julius Plücker -- discovered that they could produce light by removing almost all of the air from a long glass tube and passing an electrical current through it, an invention that became known as the Geissler tube.
