Introduction to Infrared LED 8mm

What is an Infrared LED 8mm?

An Infrared LED 8mm, also known as an 8mm infrared light-emitting diode, is a type of semiconductor device that emits infrared light when an electric current is applied to it. These LEDs are commonly used in various applications due to their compact size, efficiency, and ability to emit light in the infrared spectrum. The "8mm" refers to the diameter of the LED's lens, which is typically 8 millimeters in size. This size is ideal for numerous applications where space is limited but functionality is crucial.

How Does an Infrared LED 8mm Work?

The operation of an Infrared LED 8mm is based on the principle of the PN junction. When an electric current is passed through the PN junction, electrons and holes are recombined, releasing energy in the form of photons. In the case of an infrared LED, these photons fall within the infrared spectrum, which is not visible to the human eye. The size of the LED's lens, such as the 8mm diameter, helps to focus the emitted light into a narrow beam, making it suitable for specific applications.
