Introduction to IR LED Power

What is IR LED Power?

In the realm of lighting technology, IR LED power has emerged as a significant and innovative solution. IR LED power refers to the use of infrared light-emitting diodes (LEDs) to generate and transmit infrared radiation. These LEDs are designed to emit light in the infrared spectrum, which is not visible to the human eye. The applications of IR LED power are vast, ranging from consumer electronics to industrial automation and medical devices.

How IR LEDs Work

Infrared LEDs operate on the principle of semiconductor physics. They are made of materials such as gallium arsenide (GaAs), gallium nitride (GaN), or aluminum gallium arsenide (AlGaAs), which have a direct bandgap. When an electric current is applied to these materials, electrons are excited and move from the valence band to the conduction band. As they recombine, they release energy in the form of photons, which are infrared light. The key to the efficiency of IR LEDs lies in their ability to convert electrical energy into light with minimal heat generation. This makes them ideal for applications where heat dissipation is a concern. The infrared spectrum spans from 700 nanometers to 1 millimeter, with different types of IR LEDs emitting at various wavelengths within this range.
