Looking in the history of electric light, it was around 70,000 BC that the first lamp invented . It was made of a hollow rock or shell, filled with moss or similar material, soaked with animal fat and ignited. Wickers wren added much later on to control the lighting. The Greeks were the first to make terra cotta lamps in the 7th century BC. Read on to learn more on the history of electric light.
Early flues used for lighting fuels were beeswax, olive oil, nut oil, sesame oil etc. If we look back in the history of electric lights, it was in 180, that Humphrey Davy of England invented the first electric carbon arc lamp. Here, two carbon rods were hooked on to a source of electricity to make light. It was in1857, that A.E. Becquerel of France formulated the theory of low pressure arc lights, giving rise to the neon signs and fluorescent lights.
The first electric incandescent lamps were invented by Sir Joseph Swann and Thomas Edison during the 1870s. In these, the electricity was made to flows through the filament inside the bulb, that was resistant to the electricity. It heated up and glowed, thus radiating light.
A major turning point in the history of electric light was, when Edison created the first lamp that became the first commercially successful incandescent lamp. He also received the U.S. Patent 223,898 for his lamp in 1880a and his lamps are still used all over the world in households today.
Thomas Alva Edison did not however, create the first electric light bulb. He just improved upon a 50-year-old idea. Funding was not a problem for him as he had support of syndicate of industrial interests who had $50,000 to invest, which was a great amount at that time. Edison used smaller current, an improved vacuum inside the globe and a small carbonized filament.
He demonstrated the light bulb in 1879 and, as they say, the rest is history. This was a very important phase in the history of electric lights
