Introduction to IR LED SMD

What is an IR LED SMD?

An IR LED SMD, or Infrared Light Emitting Diode Surface Mount Device, is a compact and efficient component used in various electronic devices for the detection and transmission of infrared radiation. These LEDs emit light in the infrared spectrum, which is not visible to the human eye but can be detected by specialized sensors. The SMD (Surface Mount Device) aspect refers to the way the LED is mounted onto a printed circuit board (PCB) using surface mount technology, which allows for smaller, more compact designs.

Working Principle of IR LED SMD

The operation of an IR LED SMD is based on the semiconductor properties of the material used, typically Gallium Arsenide (GaAs). When an electric current is applied to the LED, it excites electrons within the semiconductor material, causing them to recombine with electron holes. This recombination process releases energy in the form of photons, which are emitted as infrared light. The wavelength of the emitted light typically ranges from 780 nm to 1000 nm, depending on the specific material composition and design of the LED.
