Introduction to Infrared LED 8mm

What is an Infrared LED 8mm?

An infrared LED 8mm, often referred to as an 8mm infrared LED, is a type of light-emitting diode (LED) that emits infrared light at a wavelength of approximately 8mm. These LEDs are widely used in various applications due to their compact size, efficient energy conversion, and the ability to transmit signals or data without visible light interference. The 8mm size refers to the diameter of the LED, which is a standard dimension in the LED industry.

How Does an Infrared LED 8mm Work?

Infrared LEDs work on the principle of the semiconductor junction. When an electric current is applied to the diode, electrons and holes recombine at the junction, 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 of the LED is designed to optimize the light output and the overall performance of the device.
