16W 12V DC Led Cob Strip Light Source Bulb On Board Red

It is generally believed that the electric light bulb was invented by the American Thomas Alva Edison. But if you do serious research, another American, Heinrich Go, invented the same principle and material and reliable light bulb decades before Edison, and many others before Edison also invented the light bulb. made many contributions. In 1801, British chemist Davy energized platinum wire to emit light. He also invented the electric candle in 1810, using an electric arc between two carbon rods for lighting. In 1854, Henri Goebbels used a carbonized bamboo thread, which was energized and glowed under a vacuum glass bottle. His invention today appears to be the first practical incandescent lamp. The light bulb he tested at that time could last for 400 hours, but he did not apply for a design patent in time. In 1850, the Englishman Joseph Wilson Swan began to study the electric light. In 1878, he obtained a British patent for a light bulb powered by carbon filaments in a vacuum, and began to establish a company in the United Kingdom to install electric lights in each home.
