Introduction to Infrared LED 8mm

What is an Infrared LED 8mm?

An infrared LED 8mm is a type of light-emitting diode (LED) that emits infrared light at a wavelength of 8mm. These LEDs are commonly used in various applications, including remote controls, security systems, and medical devices. The 8mm refers to the diameter of the LED, which is a standard size for many infrared applications.

How Does an Infrared LED 8mm Work?

Infrared LEDs work by converting electrical energy into light energy. When an electric current passes through the LED, it excites the electrons within the semiconductor material, causing them to emit photons. In the case of an infrared LED 8mm, these photons are emitted at a wavelength of 8mm, which is outside the visible spectrum. The key components of an infrared LED 8mm include the semiconductor material, a metal contact, and a lens. The semiconductor material is typically made of gallium arsenide (GaAs) or indium gallium arsenide (InGaAs), which allows for efficient emission of infrared light. The metal contact provides a path for the electric current to flow, while the lens helps to focus the emitted light into a narrow beam.
