A light-emitting diode (LED) is a two-lead semiconductor light source. It is a p–n junction diode, which emits light when activated. When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor.
An LED is often small in area (less than 1 mm2) and integrated optical components may be used to shape its radiation pattern.
Appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared light. Infrared LEDs are still frequently used as transmitting elements in remote-control circuits, such as those in remote controls for a wide variety of consumer electronics. The first visible-light LEDs were also of low intensity, and limited to red. Modern LEDs are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness.

It is time to learn the Essentials with Karen and Ben this week, Karen has a project that requires a bit of intelligence and discrete electronics can provide just that. To make the laser cut Star Wars BB8 art light reactive, Ben helps to explain and design a circuit using active and passive components, from resistors, capacitors and inductors to diodes and transistors. These components make the basis of smart electronics we experience today, from video cameras to smart phones. Watch now to find out how you can make your project light reactive with a photoresistor and discrete logic! Let us know what art work you have been creating, or how you would want add that bit more control on the element14 Community.

I did the coolest Nerf War Nerf Gun thing ever! #NERF I Light up my Nerf War Nerf Gun with LED lights... So easy and fun! (Be the leader of any Nerf War Master!) Previous Nerf Video (Hydro Dipping Nerf Gun): https://youtu.be/0Xh5OkqVJ1Q This VLOG is really cool and we show you a lot of awesome NERF, Nerf War, and Nerf War Master Ultimate (and other) inventions that we are doing. In the upcoming vlogs, these inventions should hopefully all work!!! I hope you all enjoy!!! #NERF Nerf War Master Ultimate features an Epic Nerf Needler Gun Mod in 4K! We've given you the Nerf Rough Cut Mod, and so this new Nerf war continues with yet another epic, deadly new Nerf Gun mod... GunVsGun style! Better believe its time for another nerf war gun game between brother vs brother, Gun vs Gun, Nerf vs Nerf....

I'm not sure of the seller of this LED mislead me by telling me it was for UK 240V electric, but when I tigged on the solders it banged really loud. I do not recommend bying LEDs from bad people becauise they go boom and may scare you. And for those who actually read down to this level... The actual result of hooking a (really crappy) 100W LED directly across 240V was so boringly controlled that I had to beef it up a bit for a second take with hidden resistors underneath for some sparks and pops. See if you can spot them as I completely lose control of the LED at least twice during the video. No good quality LEDs were harmed in the making of this video. Mainly because I can't get any.
call it a day, nothing to say
maybe it's easy that way
i don't know - you never did
i don't know - let it go
nothing to say, but it's ok
maybe you want it this way
haven't you led me long enough to throw me a bone?
haven't you bled me long enough to live on your own?
call it a day, lust made us grey
i'll always see you that way
send me away, 'cause i wouldn't stay
never lived here anyway
haven't you led me long enough to throw me a bone?
