What is meaning of LED ?

.This whole configuration is encased in epoxy which also serves the purpose of a lens. LEDs have very high thermal resistance with upwards of 200K per Watt.

Early LEDs produced only red light

LEDs can produce several different colors

LEDs are highly monochromatic, only emitting a single pure color in a narrow frequency range

LEDs are commonly used for indicator lights

The color emitted from an LED is identified by peak wavelength

They also have several other applications, including electronic signs

clock displays

which is measured in nanometers (nm).

Since LEDs are energy efficient and have a long lifespan

. The peak wavelength is a function of the material that is used in the manufacturing of the semiconductor

they have begun to replace traditional light bulbs in several areas.

Most LEDs are produced using gallium-based crystals

Some examples include street lights, the red lights on cars

that differ in one or more additional materials such as phosphorous to produce distinct colors

various types of decorative lighting

You can typically identify LEDs by a series of small lights that make up a larger display

Different LED chip technologies

enable manufacturers to produce LEDs that emit

you look closely at a street light, you can tell it is an LED light if each circle is comprised of a series of dots.

The energy efficient nature of LEDs allows them to produce brighter light than other types of bulbs while using less energy

light in a specific region of the visible light spectrum and replicate different intensity levels. Thus, one would vary the material used

For this reason, traditional flat screen LCD displays have started to be replaced by LED displays, which use LEDs for the backlight.
