Light Emitting Diodes, or LEDs as they are commonly referred to, use a different technology than traditional, incandescent light bulbs. LEDs, as their name would suggest, emit light. But instead of this happening through the heating of a lighting element such as Tungsten that occurs in an incandescent light, LEDs emit light through the movement of electrons and the resulting release of photons. To learn more, see this Wikipedia entry. What is important about this is that it occurs at an atomic level and requires much less energy for the light to be emitted.
As referenced earlier, another key characteristic of LEDs that contributes to their reduced energy usage is the fact that they do not radiate heat in the same way that incandescent light bulbs do. This not only is more efficient in the production of light, but also, the lack of heat being generated in producing the light means that very little or no energy needs to be consumed to cool the light or the surrounding area when the light is being used. This calculation is typically not included when overall energy savings achieved by an LED is considered, but could be significant if many lights that produce a lot of heat are replaced by LEDs producing relatively very little heat.
Increasingly, LEDs are also being referred to as Solid State Lights or Solid State Lighting, which refers to the type of computer technology that is used to drive the lights. Also, it alludes to the durable nature of the technologies used in these lights.
