What is the definition of LED and what are it's uses?
What are LEDs and what are they used for?
A LED or a Light Emitting Diodes are a distinctive type of diodes. Diode is a electric element that lets the electricity go by through it from a single route only. What is good on LED is that they glow or produce lights when connected to a correct electric line which is similar to a light bulb. When LEDs are settled side by side, it can produce pictures such as those moving red LED signs that we see on different areas.

Hy
LED means Light Emitting Diodes. It is one kind of lighting technology. And it can give an actual picture dimension. It can save the energy and battery life. The LED lighting quality is better than LCD or CRT. Most of the people like now LED monitor in their computer. LED cannot show negative picture in the rotation view. On the other hand LCD monitor give negative picture in the rotation view. So 180 degree is the actual rotation view for LCT, which is very disgusting.
LED lighting technology can save the electric power and which can save a lot of energy.
What are LEDs and what are they used for?
There is not much to say about LED. LED stands for Light-Emitting Diode. A diode is something that has somewhat two parts; one is that it allows electric current to pass in one direction while the other part blocks the electric current from the opposite side As we can see the meaning says “light-emitting” as sources say they emit light but not that intense. They are semiconductors of light. In the past LED only emitted low-intensity red light. LED on modern times is now used in our televisions. There are also infrared LEDs; these can be found in remote controls. I attached a photo of an example of a LED TV.
What are LEDs and what are they used for?
The full meaning of LED is Light Emitting Diode. LED is a semi-conductor device that gives light when electricity passes through it. In late 1920’s a Russian scientist created the first LED. LED is used to denote different status of electronic gadgets. It is also being used as a substitution of incandescent and NEON lights. Since LED is more efficient than those mentioned, it became ever popular within a short time.
Use of LED includes, but not limited to, indoor or outdoor lights, flashlights, security lights etc different lights, electronic signs, clock displays, car lighting and different decorative lightings. One of the most common thing that uses LED is the remote control of your television set.
What are LEDs and what are they used for?
Definition:
LED or Light Emitting Diodes are, as the name implies, diodes that glows when electric current is applied. (Diodes are electronic components that allow electricity to pass from only one direction). If you organize several LEDs alongside, they can form pictures. Such pictures you see everywhere by means of scrolling red LED signs.
Uses:
LEDs are applied in a lot of things. As lights they are used in Night lighting, Porch or outdoor lighting and art lighting. Several electronic equipments like computer, TV, DVD and MP3 players use LED.
A special type of LED lamps is used instead of regular light and night fixtures. But such bulbs are expensive. LEDs ability to be directed easily makes it very popular to use in newer flashlights.
Also, LEDs are being used in traffic lights and outdoor signs.
Even the headlights of automobiles are being replaced by LEDs now a days.
