LED lighting is Light-emitting diodes (LEDs). They are solid state semi conductor devices. Colour with LED is possible based on chemical composition of material being excited. It can produce white,deep blue, yellow,green,orange,red,bright red and deep red.

LED lighting differs from incandescent and fluorescent in several ways. When designed well, LED lighting is more efficient, versatile, and lasts longer. LEDs are “directional” light sources, which means they emit light in a specific direction, unlike incandescent and CFL, which emit light and heat in all directions.

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.

light-emitting. Is a type of device that emits visible light when an electrical current passes through it. An LED light is a type of light-emitting diode that emits visible light when an electrical current passes thought it.

A light emitting diode (LED) is a forward biased p-n junction diode That emits visible light when energized. LED work on the phenomenon of electroluminescence. The colour of light emitted depends on the semiconducting material used.

A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons.

Answer : A light emitting diode is formed by heavily doping both n and p regions of a junction diode. The entire structure is then placed in a transparent casing for the light to be emitted after recombination.

Then we can say that when operated in a forward biased direction Light Emitting Diodes are semiconductor devices that convert electrical energy into light energy. Generally, all LED’s are manufactured with two legs protruding from the bottom of the body.

What is another word for emitting light?

Light-emitting diode (LED) is a forward biased p-n junction diode which emits visible light when energized. The light energy is produced by the recombination of electrons and holes at the junction. Emit radiation in the infrared region. If light – emitting diode is reverse-biased, then no light would be emitted at all.

Light-emitting diode, usually called a LED, [1] is a semiconductor diode that emits. incoherent narrow-spectrum of light when electrically biased in the forward direction of the. p-n junction, as in the common LED circuit. This effect is a form of electroluminescence.

Light Emitting Diodes I-V Characteristics. In most cases LEDs are operated from a low voltage DC supply, with a series resistor, RS used to limit the forward current to a safe value from say 5mA for a simple LED indicator to 30mA or more where a high brightness light output is needed.

A light releasing diode is an electric component that emits light when the electric current flows through it. It is a light source based on semiconductors. When current passes through the LED, the electrons recombine with holes emitting light in the process.

When current passes through the LED, the electrons recombine with holes emitting light in the process. It is a specific type of diode having similar characteristics as the p-n junction diode. This means that an LED allows the flow of current in its forward direction while it blocks the flow in the reverse direction.

When the diode is forward biased, electrons from the semiconductors conduction band recombine with holes from the valence band releasing sufficient energy to produce photons which emit a monochromatic (single colour) of light.
