Infrared LED 5mm has become an integral part of the electronics industry, widely used in various applications. This article aims to provide an in-depth introduction to the infrared LED 5mm, covering its basic principles, applications, advantages, and future trends.

Basic Principles of Infrared LED 5mm

The infrared LED 5mm is a type of light-emitting diode (LED) that emits infrared light with a wavelength of approximately 850nm. Unlike visible light, infrared light is not visible to the human eye. The 5mm refers to the diameter of the LED's lens, which is 5mm in size. The infrared LED 5mm works on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The infrared LED 5mm consists of a semiconductor material, typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs), which emits infrared light when an electric current is applied. The semiconductor material is encapsulated in a transparent or translucent lens to focus the emitted light. The lens also helps to protect the LED from external factors such as moisture and dust.
