An LED lamp is a solid-state lamp that uses light-emitting diodes (LEDs) as the source of light. The term LED lightbulb is also colloquially used. LED lamp may in general refer to conventional semiconductor light-emitting diodes, to organic LEDs (OLED), or polymer light-emitting diodes (PLED) devices, although OLED and PLED technologies are not commercially available in 2010.
