Let's explore how LEDs - light-emitting diodes - work and their advantages over traditional light bulbs.

Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere. We offer quizzes, questions, instructional videos, and articles on a range of academic subjects, including math, biology, chemistry, physics, history, economics, finance, grammar, preschool learning, and more. We provide teachers with tools and data so they can help their students develop the skills, habits, and mindsets for success in school and beyond. Khan Academy has been translated into dozens of languages, and 15 million people around the globe learn on Khan Academy every month. As a 501(c)(3) nonprofit organization, we would love your help!

Very, Very well done.(Wish you could pre-write the words to lessen my anxiety level.) I think that there will Always be heat generation, even in recombination, albeit sooo tiny.
And a pn junction is not a diode (and vice-versa) it only contains it as do transistors, scr, jfets, ect...
Enough of my criticism. Do leds use a specific substrate instead of silicon?

You said electrons falling from conduction band to valence band..is that from n type conduction band to p type valence band??

Great video series.Many thanks for all your effort.Can you do some videos on the workings of a thyristor, triac and diac and their applications?
