Light emitting diodes are used to emit light! They can be used in flashlights, car headlights and traffic signals. Originally they were used for digital displays on clocks and calculators. There are many used for simple indicators such as on flash drives and under status lights in computer equipment. If you have a CAPS lock key light on your keyboard, it is an LED.
------------------------------------------------------
The use of LEDs is to save a electricity, they consume less power than a light bulb, and last longer.
------------------------------------------------------
LED's or `light emitting diodes' are solid state lights, meaning that they have no filament, which generate their light as power is applied to a junction which could be made up of many different materials such as gallium arsenide. Depending on the materials used, the light can be several different colors ranging from red to white and all colors between.
Many times in the epoxy shell in which the electronic junction is encapsulated, they'll add an additional `doping' compound to assist in the light producing a different or enhanced color. For instance a white LED is usually a blue LED which is `doped' to produce a white light. Over a period of time, the white LED will start to get bluish as it ages and the doping `wears out'.

1] to display a condition on a panel
2] In great quantity it can be used as a lamp or light illumination
And there many types of the same family that give out infrared. ultraviolet and many other colors just by shifting to a low or hi in the color spectrum range.
What else can I help you with?
Are colored Christmas tree leds the same as the leds used in grow lights?
No.
What can leds be used for?
lighting stuff?
Where LEDs commonly used today?
In torches,
What type of LEDs used in Xbox360 called?
LED's
What are the different types of LEDs?
There are several types of LEDs, including standard (through-hole and surface mount) LEDs, which are commonly used for indicators and displays; high-power LEDs, designed for applications like lighting; and RGB LEDs, which can emit multiple colors by combining red, green, and blue light. Additionally, there are specialized LEDs such as organic LEDs (OLEDs) for displays, and ultraviolet (UV) LEDs for applications like sterilization and curing. Each type has unique properties suited to specific applications in electronics, lighting, and displays.
Why do green leds on modern stop lights fail before leds of other colors?
Maybe it's used more? I don't Know.
Which is a more powerful light - 95 leds or 128 leds?
If your compairing apples to apples like 3 watt leds to 3w leds then 128. The more leds the higher the power.
What lights were used in car headlights before LEDs?
Halogen Bulbs
Are LEDs dimmable?
Yes, LEDs are dimmable.
Make a list of the uses for leds?
LEDs are used in traffic lights, on computer lights, car lights and indicators. You can also purchase LED flashlights and torches. Can be used in small devices for a variety of uses.
When to connect LEDs in parallel?
Basically, when LEDs are connected in parallel, the LEDs with the lowest resistance will be the brightest, the other LEDs will be dimly lit or not lit at all. Therefore, use LEDs with the same model number and colour.
What color LEDs in Gallium used to make?
Gallium nitride (GaN) LEDs are commonly used to create blue LEDs. By combining a blue LED with a yellow phosphor coating or a green and red LED, white light can be produced. Additionally, different additives can be incorporated to create other colors such as red, green, and yellow LEDs.
