Knowledge fuels change - Support energypedia!
For over 10 years, energypedia has been connecting energy experts around the world — helping them share knowledge, learn from each other, and accelerate the global energy transition.
Today, we ask for your support to keep this platform free and accessible to all.
Even a small contribution makes a big difference! If just 10–20% of our 60,000+ monthly visitors donated the equivalent of a cup of coffee — €5 — Energypedia would be fully funded for a whole year.
Is the knowledge you’ve gained through Energypedia this year worth €5 or more?
Your donation keeps the platform running, helps us create new knowledge products, and contributes directly to achieving SDG 7.
Thank you for your support, your donation, big or small, truly matters!
Light Emitting Diode (LED)
Overview
"A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. Introduced as a practical electronic component in 1962, early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet and infrared wavelengths, with very high brightness."[1]
