A light-emitting diode (LED) is a semiconductor device that emits incoherent narrow-spectrum light when electrically biased in the forward direction. This effect is a form of electroluminescence. The color of the emitted light depends on the chemical composition of the semiconducting material used, and can be near-ultraviolet, visible or infrared.
LED technology has made a big impact on both interior & architectural lighting and, more recently, on fashion and street culture. Check out the innovative Night Writer and “Throwies” from Graffiti Research Lab.
Blinking rings and scrolling belt buckles have been around for a while, but have you seen LED license plates, backpacks, shirts yet. Check out tbuckles.com.
