light-emitting diode
Noun: A light-emitting diode is a semiconductor device that emits light when an electric current passes through it. The light produced is directly proportional to the electrical current applied, and the color of the light depends on the specific materials used in the semiconductor's construction.
A light-emitting diode is used as a highly efficient, durable, and long-lasting source of light in a vast array of electronic devices and lighting applications. - It functions as the subject of a sentence: "The light-emitting diode provides bright illumination with very little heat." - It functions as the object of a sentence: "Modern televisions use a light-emitting diode for their backlighting."
- In technical specifications: The term is used to describe a component's type.
- In comparative contexts: Used to highlight advantages over other technologies.
- LED: The universal acronym for light-emitting diode.
- OLED (Organic Light-Emitting Diode): A type of LED in which the emissive layer is a film of organic compound.
- Micro-LED: A technology involving very small, individual light-emitting diodes.
- Diode: A broader category of two-terminal electronic components that allow current to flow primarily in one direction, which includes the light-emitting diode.
- LED (This is the direct and most common synonym, being an acronym for the full term).
- Solid-state lamp/lighting (This describes the technology category to which LEDs belong).
- LED screen/display: A screen whose pixels are illuminated by light-emitting diodes.
- LED bulb: A light bulb that uses one or more light-emitting diodes as its light source.
- LED driver: The power supply unit required to operate a light-emitting diode.
-
diode such that light emitted at a p-n junction is proportional to the bias current; color depends on the material used
