What is an IR LED SMD?

An IR LED SMD is a type of light-emitting diode that emits infrared light. Unlike visible light LEDs, which emit light in the visible spectrum, IR LEDs produce light in the infrared spectrum, which is beyond the range of human vision. These LEDs are characterized by their small size, high efficiency, and long lifespan, making them ideal for a variety of applications.

How Does an IR LED SMD Work?

An IR LED SMD operates based on the principle of electroluminescence. When an electric current is applied to the diode, it excites the electrons within the semiconductor material, causing them to recombine with electron holes. This recombination releases energy in the form of photons, which are emitted as infrared light. The specific wavelength of the emitted light depends on the composition of the semiconductor material used in the LED.
