How Do LED Lights Work?

It’s really simple actually, and very cheap to produce, which is why there was so much excitement when LED lights were first invented!The Technical Details: LEDs are composed of two types of semiconducting material (a p-type and an n-type). Both the p-type and n-type materials, also called astringent materials, have been doped (dipped into a substance called a “doping agent”) so as to slightly alter their electrical properties from their pure, unaltered, or “intrinsic” form (i-type).The p-type and n-type materials are created...

How LEDs are Different

LED lighting is very different from other lighting types such as incandescent and CFL. Key differences include:Light Source: LEDs are the size of a fleck of pepper, and can emit light in a range of colors. A mix of red, green, and blue LEDs is sometimes used to make white light.Direction: LEDs emit light in a specific direction, reducing the need for reflectors and diffusers that can trap light. This feature makes LEDs more efficient for many uses such as recessed downlights and...

Energy Savings

LED is a highly energy-efficient lighting technology, and has the potential to fundamentally change the future of lighting in the United States.  Residential LEDs -- especially ENERGY STAR rated products -- use at least 75% less energy, and last up to 25 times longer, than incandescent lighting.Widespread use of LED lighting has a large potential impact on energy savings in the United States. By 2035, the majority of lighting installations are anticipated to use LED technology, and energy savings...
