Essay about Advantages Of The Electric Light Bulb
A short glance back over the history of the light bulb: Most people think that Edison invented the electric light bulb, but that is not true. The first light bulb was created in 1835. Edison would patent his bulb 44 years later in 1879. Scientist from around the world would spend the next 31 years trying to build a filament that would have a long life and be cost effective. It wasn’t until 1910 when William Coolidge invented the tungsten filament that is still used today. The tungsten filament outlasted all other types of filaments and Coolidge made the costs practical, but could not make the bub efficient.
LED vs. Incandescent
While electrical technology has dramatically changed over the years the electric light bulb has not evolved in 104 years. In today’s electrical field one of the most important factors is energy conservation. By today’s energy standards the incandescent light bulb is one of the most inefficient inventions ever created. The modern LED light is the most efficient light on the market today.…
