Each small step is a big invention - Lighting our lives

A light bulb flashing over the head of a lone scientist is the universal symbol of invention.

Just imagine if there were no electric lamps, how life would have been after sunset or in darker places !! How life woud have been in Northern Europe during the winters, when the days are very short!! How would traffic run on roads with no lights!! Do you think, candles and lamps would have been enough for all this? No way...life would have been dull and boring without the electric lights.

Electric lamps have been one of the greatest inventions. They have made our lives comfortable in many ways. Many inventions have taken several centuries to develop into their modern forms. A light bulb is no exception. It is one of the best inventions.

Do you know Thomas Alva Edison didn't "invent" the light bulb. He actually improved upon a 50-year-old idea. In 1809, Humphry Davy, an English chemist, invented the first electric light. In 1878, Sir Joseph Wilson Swan, an English physicist, was the first person to invent a practical electic lightbulb (13.5 hours). In 1879, Thomas Alva Edison invented a carbon filament that burned for forty hours. Edison placed his filament in an oxygenless bulb. Edison continued to improved his lightbulb until it could last for over 1200 hours. In 1991, Philips invented a lightbulb that lasts 60,000 hours.

So you see, how this important invention, that has given light to our lives, has evolved over time. The modern day lamps, different colours, sizes, and types for different uses, all originate from the early inventions. Today, it is very difficult to imagine life without electric lamps.

Each invention may be just one small step on the road to the ultimate goal.
