Light Bulb, Invention and Purpose

In 1880, Thomas Alva Edison invented an incandescent bulb and applied for a patent. This is an invention that has existed since the 1800s. The invention makes a big impact on society by making the world comfortable and creative.

Safe environment. Edison proposed a 16 watt bulb that lasts more than 1,500 hours. Edison's light bulb needs improvement, and these improvements are bulbs that we have today. the reason

Light bulbs were invented using low current electricity, small carbonized filaments, and worldwide improved vacuum; this is not the first invention of Edison, but Edison 's invention of 50 years ago.

Edison's bulb design has a vertex, but it looks like a bulb you see today. The socket is on the base just like the light bulb used today. The lamp has a thin carbonized cotton filament sealed in a fragile glass vacuum tube. The bulb works through the filament through direct current

Edison experimented with more than 6,000 filaments and chose a perfect filament that glows and lasts longer. He also experimented with many different materials and studied the efficiency of different filament diameters, structures and shapes.

He looked at unconditional clues left behind. He tried the oval and horseshoe shaped filaments. He also decided to remove air from the tube using a vacuum pump or to burn filaments until the filament was oxygen free. Edison can produce reliable, lasting light sources. The concept of electric lighting is not new, and many people are studying and further developing the form of electric lighting. If it is not Thomas Edison, we will use candles, oil lamps and gas lamps as light sources.

Today, bulbs are used for lamps, ceilings, car headlights, street lights, Christmas lights, and so on. Light bulbs are evolving to colored lights, compact fluorescent lights (CFL), and various other types.

In the case of electric lighting, the influence of Edison's innovative products is historically important. His work helped future future inventors show its direction. Vacuum tubes are still in use today, which captures the improvements of the present invention used by Edison. It provides the industry with a foundation for efficient lighting systems

Edison's representative invention is a light bulb. When the oatmeal cartoon said, "Edison did not invent the bulbs," he quickly pointed out this he improved the idea of ​​the other 22 people who made the light bulb. Edison figured out how to sell a light bulb just before him. "However, oatmeal is incorrect First of all, I think that the invention of engineering and science is almost the improvement of the invention of the previous, for example, improvement of exchanges of Tesla This is innovation, this is a society to happen "Social process in the background As Robert Hainline once said," You can make a railroad when the train's time comes, but it was not possible in the past, in other words, Was conducted in the context of scientific and engineering understanding.

Thomas Edison is known for inventing light bulbs. Contrary to the general belief, Edison did not invent a light bulb; it had been for many years. However, the lighting at that time was low in reliability, expensive and short-lived. When Edison participated in the light bulb invention competition, other inventors all over the world had already made over 20 different efforts. By finding the vacuum inside the bulb, finding a suitable filament to use, and applying a lower voltage through the light bulb, Edison can achieve a bulb that lasts hours. This is a substantial improvement and brings further improvements to make the light bulb practical and economical.
