As we say at The Frugal One, every penny counts, and we really mean that. If you want to save a large sum of money every week, the little things you change are what will add up into pounds saved.
Save money lighting your home
A great example of this is saving on the cost of lighting your home. Recent studies have shown that the average UK family can save around £240 a year on their electric bills simply by switching to LED light bulbs.
How LED Bulbs Work
The principal behind LEDs is deceptively simple. An electrical current is passed through a material that reacts with the current and glows. This produces a usable light. They do not produce light in the same way as incandescent light bulbs the light in these bulbs is a by-product of heating an element. With LEDs, electrical excitement generates the light, rather than heat.
How LEDs Were Developed
LED lights have been around for far longer than many people realise. The science behind Light Emitting Diodes has been around since 1907. Around that time, HJ Round, who worked for Marconi, experimented with passing a small electrical current through a range of materials.
He and his team were surprised to find that some of these materials provided a viable light source. They were the pioneers of electro luminesense. However, at the time, there was no practical use for their invention, so it was shelved. In 1927, Oleg Vladimirovich Losev created the first proper LED, but there was still no use for it. In 1955, Rubin Braunstein produced light by passing electric through gallium arsenide. There was interest from the scientific world, but not the commercial world.
Nick Holonyak Jr. Developed a Light Emitting Diode that produced a light that was bright and could be produced consistently in 1962. George Craford improved the quality of red and orange LED lights and developed yellow LEDs.
The first commercial use of LED light was in digital displays. In the mid 70s, they were used in calculators, digital watches and technical instruments. However, they were red, so no good for use as a light source. Blue LEDs had to be developed to allow that. The Shuji Nakamura of Nichia Corporation were both instrumental in this development, but it took until the late 90s to achieve this.
The Structure of Modern LED Bulbs
Most lighting LEDs give off blue light. The diode is made up of very thin layers of crystalline that act as a semi-conductor. One layer has an excess of electrons and the next a deficient. When electricity is passed through the diode, the neutrons pass between each layer repeatedly. The energy involved in this process manifests itself as light.
Save Money Make the Switch to LED Lighting
We hope that now you know a bit more about what LEDs are, how they were developed and how they work, you will feel confident about buying them and using them in your home. Over the course of a year, you can save a significant amount of money.
