NECESSITY is the mother of all INVENTIONS. What we reap is what we have sown in the past. However, maintaining and managing the seeds and crop is even crucial step. Experiencing illuminated moments with LEDs and advance lighting devices are the outcomes of some wonderful innovations. The series of inventions generated during various stages actually changed the way of our living style and thinking pattern. One of the examples of such changes is witnessed in energy sector too, where we have seen many breakthroughs from power plants and electric transmission lines to home appliances and electric motors. The invention of Light bulb made it a symbol of innovation. Light bulb is included in the list of greatest invention of the century.

As generally believed, Thomas Alva Edison did not “invent” the first light bulb. The true light bulb was first invented in 1854 by Henricg Globel, a German watchmaker. He used a carbonized bamboo filament placed inside a glass bulb. Two patents were granted to Henry Goebel in 1882 for an improvement of the Geissler-System of vacuum pumps and a solution to connect carbon-filaments and metal-wires in a light bulb. In 1875, Herman Sprengel invented the mercury vacuum pump making it possible to develop a practical electric light bulb. in 1875, Henry Woodward and Matthew Evans patented a light bulb.

Before ‘inventing’ famous Light Bulb, Thomas Edison with Sir Joseph Swann invented the first electric incandescent lamps during the 1870s. Edison’s lamp became the first commercially successful incandescent lamp. Edison received U.S. Patent 223,898 for his incandescent lamp in 1880. Incandescent lamps are still in regular use in our homes.
