What is a light emmitting diode lead in
0:02
physics? Definition: A lightemitting
0:04
diode lead is a special type of diode
0:07
that produces light when electric
0:09
current flows through it in the forward
0:12
direction. Explanation inside and lead
0:15
electrons move across a semiconductor
0:18
junction P and junction. When these
0:20
electrons recombine with holes, they
0:23
release energy in the form of light, a
0:25
process called electroluminance.
0:28
Unlike ordinary bulbs, leads don't use
0:30
heat to make light, making them energy
0:33
efficient and long-asting. Types of
0:35
leads. One, visible leads produce
0:38
colored lights, red, green, blue, etc.
0:42
Two, infrared leads used in remote
0:45
controls and sensors. Three white leads
0:48
used in bulbs, torches, and phone
