Definition of LED

LED - A Light Emitting Diode (LED) is a solid-state semiconductor device that converts electrical energy directly into light.

On its most basic level, the semiconductor is comprised of two regions. The p-region contains positive electrical charges while the n-region contains negative electrical charges. When voltage is applied and current begins to flow, the electrons move across the n region into the p region. The process of an electron moving through the p-n junction releases energy. The dispersion of this energy produces photons with visible wavelengths.

Levels:Level 1 - The chip or die
Level 2 - The LED component
Level 3 - LED array; may include optics, heat sink and/or power supply
Level 4 - LED luminaire

The environmental implications - no UV Rays or gases are released into the atmosphere. The perfect solution to providing a low energy consumption option in landscape lighting.

Hope this helps,

Designs With Green in Mind

"Today LEDs are in the early stages of penetrating the lighting market. However, the technology is advancing quickly, and LEDs have begun to be used in a wide variety of lighting applications," as stated in Strategies in Light Magazine (www.strategiesinlight).

One such technological advance is in the field of LED landscape lighting. LED lights use 1/5th the energy of incandescent fixtures which is equal to 80% less energy. In addition, LEDs are environmentally friendly with no mercury gases released into the atmosphere.

Over the next few posts, I will spend some time explaining more about the benefits of LED and what role these exciting fixture will play in the next generation of Green, Affordable or Sustainable lighting.
