What is an SMD IR LED?

An SMD IR LED is a type of light emitting diode that emits infrared radiation. Unlike traditional LEDs that emit visible light, SMD IR LEDs are designed to emit light in the infrared spectrum, which is not visible to the human eye. This makes them ideal for applications where invisible light is required, such as remote controls, security systems, and medical devices.

How Does an SMD IR LED Work?

The working principle of an SMD IR LED is based on the semiconductor material, typically gallium arsenide (GaAs), which emits light when an electric current is applied. When the current passes through the diode, electrons recombine with electron holes, releasing energy in the form of photons. In the case of an SMD IR LED, these photons fall within the infrared spectrum, producing invisible light.
