A semiconductor diode which emits incoherent light when a current is passed through it. Used as a light source in fiber optic transmission.
An electronic device that gives off light when an electric current is passed through it. Most indicator lights, such as the one that comes on when you switch on your PC use an LED.
A diode, or two-state device, that emits light in one state ("on") and does not emit light in the other ("off"). LEDs are used to indicate problems or diagnostic codes.
A small diode device which passes current in one direction and lights whenever a voltage above a certain level is fed to it.
A semiconductor device that emits incoherent optical radiation when biased in the forward direction.
A type of light source that when stimulated by electricity generates an infrared frequency
a semi conducting device that emits light when an electric current runs through it
a semiconductor device that emits incoherent light when a current is passed through it
A gallium-arsenide diode that emits energy as light. Often used on automotive indicators.
A solid that directly converts electrical impulses into light. Some LED's today incorporate fluorescent materials to change the color characteristics of the emitted light.
A semiconductor device used to transmit light into a fiber in response to an electrical signal. It typically has a broad spectral width.
A light emitting diode (LED) is a semiconductor device that emits light when voltage is applied between its terminals.
A device that converts applied voltage to light. LEDs appear as colored lights that indicate operating conditions.
A semiconducting diode that emits light when forward biased
A solid-state, light-emitting device that is used in some imaging systems.
a semiconductor device composed of a P-N junction designed such that electrons emit visible light during their migration across the junction.
A type of semiconductor device that conducts current in one direction only and emits light.
A device used in a transmitter to convert information from electrical to optical form. It typically has a large spectralwidth.
A semiconductor device that emits incoherent light formed by the P-N junction. The light intensity is roughly proportional to electrical current flow. See Photo
This piece of electronics emits light when a current is passed through it. It does not work the same way as a light bulb, so it does not have the problem...
A diode that lights up when a voltage is applied to it. This diode is made of a substance that illuminates when electricity passes through it.
LED; A solid state light source component that emits light or invisible infrared radiation.
A diode emitting light when operated in a forward direction. Diodes have nearly zero forward resistance, therefore must a series current limiting resistor is required.
Special diodes that emit light when connected in a circuit. The LED consists of two wires that have been encapsulated in a small amount of plastic. Between these two wires are two pieces of semi-conductor. When electricity is applied through one of the pieces of wire, it travels up the wire through the one piece of semi-conductor and “jumps” to the other side. When it “jumps”, it emits a tiny photon of light. Different semi-conductors produce different colors.
a diode junction formed by compound semiconductors that emits light when forward biased.
(light emitting diode): An efficient source of electrical lighting, typically lasting 50,000 to 100,000 hours.
(LED): A diode constructed in such a way as to generate a source when biased in a forward direction.
A special diode which emits light when connected to a circuit. They are frequently used as a source of light in electronic appliances and signs.
A diode is a semiconductor device through which current can go in only one direction. As a side effect, light-emitting diodes produce either visible or infrared light and require very little power.
A fiber-optic light source.
A semiconductor device which emits incoherent light from a p-n junction (when biased with an electrical current). Light may exit from the junction strip edge or from its surface (depending on the device's structure).
