How LED lights work
LED lights are a popular technology that is being developed and researched further so it can replace light bulbs of the past such as incandescent light bulbs and CFL bulbs. There are a few things that you should know before the technical parts are explained.
First of all, LED stands for light emitting diode. It is a type of solid-state lighting also called an SSL. An SSL gives
light from a solid object or piece of matter. Generally, the semi-conductor is what most LEDs use to give off light. Without getting too technical, light is given off when there are electrons moving around inside of its semiconductor. Now, there are some more technical details involved.
The semiconductor in LEDs is made from a piece that is negatively and positively charged. The positive layer of the component has holes for electrons to travel through. The negative part of the component has electrons inside of it. When the semiconductor is hit by an electric charge, electrons begin to move from the negative to the positive part of the semiconductor. The light is given off when the electrons move into the positive section of the semiconductor through the holes that were made.
In the past, there was a problem with LED lights being used for home lighting. A large portion of the light that was being given off from the LED was getting stuck inside the light. As a result, people generally wanted a brighter light. Though through more recent discoveries, LEDs are now able to emit just as much light as other lights. What makes LED lights so special is the amount of light that it generates in relation to the amount of power they use.
The easiest way to explain how an LED light is more efficient than other light bulbs is with a real example. An incandescent bulb can produce 60 watts of light with 60 watts of power. However, an LED light can produce the same 60 watts with only 7.5 watts of power. To put it plainly, LED lights are able to generate the same amount of power as other lights but require much less electricity to do so. This makes it a much more energy efficient light bulb. LED lights also beat other lights in terms of their life span. An LED light can produce light for around 50,000 hours. This means that not only does it require less electricity to function, but it also last longer than other light bulbs. LED lights are one of the best light technologies available because of its efficiency and long life.
