Most individuals think that the LED light bulb is a comparatively new innovation. But it may come as huge surprise to discover that in fact these types of lights were actually developed more than a century ago.

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

Around 1907 in the laboratories of Marconi experiments were being carried out using semiconductors to see what they were capable of doing. During only one such experiment being performed by Henry J Round it was revealed that the junction of semiconductor had the capability to emit light. But during his experiments he used silicon carbide and since the light emitted was so dim they thought using semiconductors in this way was futile. In turn this resulted in them thinking that further researches would not be needed.

There was an era when the solar panel price was extremely high that it excluded the most of people from using solar panels. This has changed for a number of reasons.

At about the same time however several similar experiments were being conducted in Germany and Russia. Then in 1920, Oleg Vladimirovich Losev efficiently produced the first light emitting diode. However because his work didn't get the international acclaim he thought it would what he had invented went virtually unnoticed.

When it comes to household fans, there are numerous distinct styles to choose from. On the list of most popular of course is the ceiling fan, which could be bought along with a bunch of distinct options.

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

This unique phenomenon was then subjected to a lot of research and more experiments during the later part of the 20th Century. Then in the 1950's that British Scientists developed the first infrared LED light bulb. In the experiments used to create such the semi conductor known as Gallium Arsenide was used. Development of this sort of LED light bulb was in its initial stages and in order to emit light at room temperature a lot of effort was necessary. Furthermore all the LED bulbs designed during this time would have to be immersed in liquid nitrogen when being operated.

We have been learning quite a lot on the web about magnet generators and their capacity to generate free energy. The idea that we could produce our own energy by simply constructing a device using affordable magnets is absolutely amazing.

Further experimentation took place and then in 1962 a research expert 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 very first visible spectrum light. It was this invention that helped to change the way LEDs were considered. It was his experiments that helped him to then become known as the father of LEDs. But it wasn't only him but additionally one of his students (M George Craford) who was laboring on such. M George Craford first developed an LED light bulb that produced yellow light before then in 1972 coming up with models that were able to emit light in red and red/orange colors.

I've a friend who is complaining of too much home heating (and cooling) expenses, so I asked her - "do you have a 7 day programmable thermostat?" She looked at me funny and said "Huh?"

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