The underlying process involves the recombination of electrons and holes in the material. Check out this video for a quick summary and visualization. An LED is a diode, or a PN junction.

LED lights are one of the most commonly used devices in the modern world. Recycling is indeed possible, but it's a little ...

1 shows a white-light LED in action). It is possible to generate light in semiconductor materials (such as GaN or AlInGaP) by injecting electrons into the conduction band of the material and ...

You can help prevent these issues by looking for LED bulbs that have weighty aluminum heat-sink materials, but ultimately LED bulbs won't perform the same in high heat conditions. In electrical ...
