Evolution of the Light Bulb

  1. 1. Evolution of the Light Bulb The history of something as revolutionary as the light bulb I would have to say is probably not common knowledge to the average person walking the planet. When we think of the history of the light bulb, where does your mind take you? I would be willing to bet you immediately go to Thomas Edison, the man who invented the basic incandescent light bulb that we know and “used to” love. This invention is already over 140 years old, and actually the first concept and working incandescent light was created over 75 years before Edison even filed his patent. It was in 1802 when Humphry Davy (ever heard of him?) passed a current through a piece of platinum, basically making the first filament and incandescent light.
  2. 2. Take a look at the graphic for more details and information on the history of the light bulb. You may learn something…I know I did. I always thought that Heinrich Gobel was full of bologna, thanks to research published in 2007 we now know the real truth. Hold on to your hats…the first practical LED was created in 1962! 60 years ago! For a lot of us this is new technology, and is now being used in just about every industry you can think of and it shows no sign of slowing down. In the last year we have created two new LED display lights for the trade show industry that are cutting edge. The next step, which is a big one for those of us in the trade show industry, is the halogen lamp, invented in 1959. This was/is still an extremely common way to cast a lot of light with a relatively small lamp. I would say the next big step in the evolution of lighting would be to fluorescent in 1934. Another form of lighting that is over 75 years old that is still widely used today. In fact maybe today more so than ever, especially in the household. In the trade show industry it is still common practice to use them for backlighting in light boxes and other signage.
