Discovery And Evolution Of LED Light Bulb


Most individuals believe that the LED light bulb is a relatively new innovation. But it may come as big surprise to discover that in reality these kinds of lights were actually invented more than a century ago.

The first models of light emitting diode (LED) bulbs made were only able to emit a very dim yellow light. They weren't actually able to emit the kind of bright light that the models available today can.

Around 1907 in the laboratories of Marconi experiments were being undertaken using semiconductors to observe what they were capable of doing. During just one such experiment being done by Henry J Round it was revealed that the junction of semiconductor had the ability to produce light. But during his experiments he used silicon carbide and since the light emitted was so dim they thought using semiconductors in this method was useless. In turn this resulted in them deciding that further experiments would not be needed.

Probably the most current introductions into the renewable energy market certainly is the zero point energy generators. This particular system has been confirmed to handle the power loads to supply electricity to homes and enterprises.

At about the same time however a number of similar experiments were being carried out in Germany and Russia. Then in 1920, Oleg Vladimirovich Losev efficiently developed the first light emitting diode. But because his work didn't get the international recognition he thought it would what he had created went virtually unnoticed.

Then in 1936 a breakthrough took place when a paper written by George Destriau on experiments with Zinc Sulphide powder was published. His concept of electroluminescence gained acclaim all over the world after he detected light when an electric energy was passed through the zinc sulphur powder during an investigate.

This particular phenomenon was then subjected to a lot of research and more experiments during the latter part of the 20th Century. It was then in the 1950's that British Scientists made the first infrared LED light bulb. In the experiments used to build such the semi conductor termed as Gallium Arsenide was used. Development of this type of LED light bulb was in its initial stages and in order to emit light at room temperature a great deal of effort was needed. Furthermore all the LED bulbs designed during this time would have to be immersed in liquid nitrogen while being operated.

Electric powered wall sconces have been used as porch lamps for as long as I can recall, however for many people that is as far as it goes.

Further research took place and then in 1962 a research specialist for GEC (General Electric Company) on the name of Nick Holonyak Jr was able to create a red light that turned out to be the first visible spectrum light. It was this discovery that helped to change the way LEDs were considered. It was his experiments that helped him to then become recognized as the father of LEDs. However it wasn't only him but also one of his students (M George Craford) who was laboring on such. M George Craford first developed an LED light bulb that emitted yellow light before then in 1972 coming up with ones that were able to emit light in red and red/orange colors.

I sense I am drowning in electrical cost every month. Do you feel the same? You can certainly do something about this and you can easily start today. There are several basic steps that you may start taking immediately.

So really as you may notice from above the creation of the LED light bulb is something that should be taken lightly.
