LED : Light Emitting Diodes

In general you must know the term LED. If not Don't worry i am not going to teach you the lesson on it. We all have our super guru/master/mentor Mr. Google with us.

Briefing the term LED

LED's are the diodes that emit light when biased properly. LED's are available in a variety of colors, such as red, yellow, and green. Some, such as infrared LED's, emit light that is not visible to the naked eye.

The color emitted by a given LED depends on the combination of elements used to produce the component. LED's are generally produced using gallium (Ga) and one or more of the following elements: arsenic (As), aluminium (Al), indium (In), phosphorus (P), and nitrogen (N). Some common element combinations are identified in data given below. Most LED's have a forward current (I)Forward limit of 100 mA or less.


Compound        Color Emitted

GaAs                   Infrared (invisible)
AlGaAs                Red
GaP                    Green
AlGaInP               Amber (yellow)
AlGaInN              Blue

Application of LED

There is a wide range of applications in which LED's are to be used. Starting from lightning technology, automobile industry, home application, signaling/signage application and a long range of its product. 

Do you know that LED light can damage your eyes?

In a study it was found that exposure to Light-emitting diode (LED) Lights can cause irreparable harm to the retina of the human eye.

According to Dr. Celia Sanchez Ramos, investigator at Madrid's Complutense University, once the retina cells are destroyed by prolonged and continuous exposure to LED rays, they cannot be replaced and will not regrow. This is caused by the high levels of radiation in the 'blue band', and is likely to become a global epidemic in the medium terms given that computer, mobiles and TV screens, and even traffic and street lights, have been gradually replaced with LED.

LED lights are made up of rainbow longitude waves, and it is the blue part, which causes the problem. LED is fantastic if there is adequate protection. Experts are calling for the lights to have built-in filters to cut out the blue glare.

Humans have their eyes open for around 6000 hours a year, and most of this time they are exposed to artificial light for which reason the best way to prevent damage is to close ones eyes often to soften the impact. Using good sunglasses with UV filter rays, and a healthy and varied diet rich in Vitamin A found in spinach and peppers-will protect the eyes.

In addition to these reduce the screen time as much as possible. Eat healthy green vegetable, leafy vegetables. protect your eyes from harmful lights.

Sanskrit is a language which people dead to be about 7-
