LEDs are part of a family of lighting technologies called Solid-State lighting (SSL), and is most commonly seen in the form of Light Emitting Diodes (LEDs), when applied efficiently can revolutionize the efficiency, appearance, and quality of lighting as we know it.
What is Solid-State Lighting (SSL)?
Solid-State lighting refers commonly to light emitted by solid-state electroluminescence, as opposed to incandescent bulbs (which use thermal radiation) or fluorescent tubes. Compared to incandescent lighting, SSL creates visible light with reduced heat generation or parasitic energy dissipation. Most common "white" LEDs convert blue light from a solid-state device to white light spectrum using photoluminescence, the same principle used in conventional fluorescent tubes.
The U.S. Department of Energy (DOE) estimates that the rapid adoption of LED lighting in the U.S. over the next 20 years can:
