What is an LED Light Bulb?

Not too many people think long and hard about the light bulbs they use in their home, vehicle, and office, and probably even less about those lighting up streets and road signs. LED light bulbs are becoming a popular choice in many of these applications, and have environmental environmental advantages over the traditional incandescent bulb. But what is an LED light bulb, and why is it so much better than the other light bulbs on the market?

The term LED stands for light-emitting diode, and the diode is actually a type of semiconductor that, through a chemical process, is able to emit light. Because of this, LED light bulbs do not have a filament inside that burns to create light, as do incandescent bulbs, and this makes them much longer lying. It also prevails them from heating up and getting got to the touch. LED light bulbs are typically very small, usually no bigger than a pencil eraser, and are put together in large numbers to create light over a larger surface area.

Because LED light bulbs are much more energy efficient and also last much longer than other types of light bulbs, they are increasingly found in commercial uses, such as traffic lights and road signs. However, new technology is making them more convenient and affordable for personal use as well, and many people are choosing to make the initial investment in LED light bulbs in order to save on energy costs and also lower their environmental footprint. An LED light bulb can last ten times as long as an incandescent bulb, which also amounts to less materials in our landfills. Overall, LED light bulbs are becoming a very popular choice for people who care about the environment and also want to save a little bit of their pocket money in the process.
