Thomas Edison invented the incandescent light bulb- if that's what your asking, although people have been burning candles, gas, wood, other things to make fire to see by for a long time.
my Friend this is not small question, its very very big question,
-----GOD IS MY ANSWER----
he took many years. The main hurdle was to find a material (tungsten) that could channel electricity through itself without melting after a few minutes.
The first lamp was invented around 70,000 BC. A hollow rock, shell or other natural found object was filled with moss or a similar material that was soaked with animal fat and ignited. Humans began imitating the natural shapes with manmade pottery, alabaster, and metal lamps. Wicks were later added to control the rate of burning. Around the 7th century BC, the Greeks began making terra cotta lamps to replace handheld torches. The word lamp is derived from the Greek word lampas, meaning torch.
In the 18th century, the central burner was invented, a major improvement in lamp design. The fuel source was now tightly enclosed in metal, and a adjustable metal tube was used to control the intensity of the fuel burning and intensity of the light. Around the same time, small glass chimneys were added to lamps to both protect the flame and control the flow of air to the flame. Ami Argand, a Swiss chemist is credited with first developing the principal of using an oil lamp with a hollow circular wick surrounded by a glass chimney in 1783.
In 1792, the first commercial use of gas lighting began when William Murdoch used coal gas for lighting his house in Redruth, Cornwall. German inventor Freidrich Winzer (Winsor) was the first person to patent coal gas lighting in 1804 and a "thermolampe" using gas distilled from wood was patented in 1799. David Melville received the first U.S. gas light patent in 1810.
Early in the 19th century, most cities in the United States and Europe had streets that were gaslight. Gas lighting for streets gave way to low pressure sodium and high pressure mercury lighting in the 1930s and the development of the electric lighting at the turn of the 19th century replaced gas lighting in homes.
Sir Humphrey Davy of England invented the first electric carbon arc lamp in 1801. A carbon arc lamp works by hooking two carbon rods to a source of electricity. With the other ends of the rods spaced at the right distance, electrical current will flow through an "arc" of vaporizing carbon creating an intense white light. All arc lamps use current running through different kinds of gas plasma.
A.E. Becquerel of France theorized about the fluorescent lamp in 1857. Low pressure arc lights use a big tube of low pressure gas plasma and include: fluorescent lights and neon signs.
Sir Joseph Swann of England and Thomas Edison both invented the first electric incandescent lamps around the 1870s. Incandescent lightbulbs work in this way: electricity flows through the filament that is inside the bulb; the filament has resistance to the electricity; the resistance makes the filament heat to a high temperature; the heated filament then radiates light. All incandescent lamps work by using a physical filament.
Thomas A. Edison of the United States invented the first commercially successful incandescent lamp around 1879. Incandescent lamps are what we regularly use in our homes.
Charles F. Brush of the United States invented the carbon arc street lamp in 1879.
American, Peter Cooper Hewitt patented the mercury vapor lamp in 1901. This was an arc lamp that used mercury vapor enclosed in glass bulb. Mercury vapor lamps are the forerunners to fluorescent lamps. High pressure arc lights use a small bulb of high pressure gas and include: mercury vapor lamps, high pressure sodium arc lamps, and metal halide arc lamps.[
Georges Claude of France invented the neon lamp in 1911.
American, Irving Langmuir invented the electric gas-filled incandescent lamp in 1915.
Friedrich Meyer, Hans Spanner, and Edmund Germer patented a fluorescent lamp in 1927. One difference between mercury vapor and fluorescent lamps is that fluorescent bulbs are coated on the inside to increase efficiency. At first beryllium was used as a coating however, beryllium was too toxic and was replaced with safer florescent chemicals.
In 1962, General Electric patented an arc lamp called a "Multi Vapor Metal Halide" lamp.
