Compared to traditional lighting sources, LEDs are more energy efficient. For instance, an average sodium vapor street light produces 1,000 watts, while an LED light can produce up to 85% less.
In addition to being energy efficient, LED lights are also very durable. They have a lifespan of 20,000 hours or more. This makes them ideal for use in a variety of locations.
Unlike incandescent light bulbs, LEDs don't get hot when in use. This makes them a good choice for outdoor settings. They are also able to withstand higher levels of vibration. They are also extremely portable. They can be plugged into a standard Edison outlet and can even be battery-run.
LEDs are also environmentally friendly. Many people are moving toward more eco-friendly options, which can help reduce the impact of global warming.
The first LEDs were invented by a young scientist at General Electric. In the early 1960s, he discovered that when an electrical current passed through a semiconductor material, the result was a bright light.
These light-emitting diodes were first used to display indicators on circuit boards. The technology later paved the way for the creation of solid-state transistors. Then, researchers started experimenting with different chemical substrates to create LEDs.
LEDs are currently used as backlights for televisions, smartphones, and other devices. They are also replacing incandescent and halogen lights. In fact, the Department of Energy estimated that by 2027, switching to LED lighting could save businesses about $30 billion.
