Running LEDs from an AC supply
WEBMay 2, 2006 · To run an LED-based fixture from a mains supply (e.g. 120 V AC) requires electronics between the supply and the devices themselves to provide a DC voltage (e.g. 12 V DC) capable of driving several LEDs. A new approach is to develop AC-LEDs, which can operate directly from an AC power supply. This provides several advantages, as …

Terminology: LED efficiency - LEDs Magazine
WEBApr 1, 2005 · LEDs are semiconductor devices that emit light via the recombination of electrons and holes within the active region (a sequence of specially designed layers) of the device. Most of these recombination events are termed “radiative” because they result in the production of a photon of light. The wavelength of the emitted light is determined ...
What is an LED? - LEDs Magazine
WEBSep 1, 2004 · In the simplest terms, a light-emitting diode (LED) is a semiconductor device that emits light when an electric current is passed through it. Light is produced when the particles that carry the current (known as electrons and holes) combine together within the semiconductor material. Since light is generated within the solid semiconductor ...
