All You Need to Know About LEDs

Quote:
An Light Emitting Diode is an electronic device that emits light when current is passed through it. LEDs are small, extremely efficient, bright, cheap, electronic components. People think that LEDs are just common light emitting components & tend to overlook the Interesting Facts & Features of LEDs. In this instructable I will teach you 'All You Need to Know About LEDs' which includes their Working, Voltage, Current and Power Ratings, Builds, Types, Resistor Calculator for LEDs, Uses, Testing & a Simple LED circuit.

    In addition to these features ,LED can also produce voltage when light falls on the junction.
    I had done some experiments on that and found that
    crystall(transparent) LEDs produce maximum voltage when compared to others

    #-Link-Snipped-# : You should think about why the LED is doing what you claim it is doing. 😉

    I would have a doubt on the current produced by incidence of light though, LEDs and photodiodes have different optimisation parameters.

    If it makes the importance of LEDs stand out any better, consider this: This year's Nobel Prize winners in Physics have won it for invention of Blue LEDs (in early 1990s), source: BBC.
