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 electronic component that emits infrared light. These LEDs are widely used in various applications due to their compact size, low power consumption, and ability to transmit signals without the need for line-of-sight communication. The 8mm refers to the diameter of the LED, which is a standard size for many optical devices.

How Does an Infrared LED 8mm Work?

Infrared LEDs work on the principle of semiconductor physics. When a current is applied to the diode, electrons and holes are recombined, releasing energy in the form of photons. In the case of an infrared LED, these photons are in the infrared spectrum, which is beyond the visible range of human eyes. The 8mm size is a result of the manufacturing process, which allows for efficient packaging and heat dissipation.
