What is an Infrared LED SMD?

An infrared LED SMD is a type of light-emitting diode (LED) that emits infrared radiation. Unlike visible light, infrared radiation is not visible to the naked eye. It falls within the electromagnetic spectrum, with wavelengths longer than those of visible light but shorter than those of microwave radiation. Infrared LEDs are commonly used in various applications, including remote controls, security systems, medical devices, and consumer electronics.

How Does an Infrared LED SMD Work?

An infrared LED SMD operates based on the principle of the PN junction. When an electric current is applied to the diode, electrons and holes recombine, releasing energy in the form of photons. In the case of infrared LEDs, these photons have longer wavelengths, resulting in the emission of infrared radiation. The process of converting electrical energy into infrared light is highly efficient, making infrared LED SMDs a preferred choice for various applications.
