Introduction to Infrared LED 3mm

What is an Infrared LED 3mm?

An infrared LED 3mm is a type of light-emitting diode (LED) that emits infrared light with a diameter of 3 millimeters. It is commonly used in various applications due to its compact size, low power consumption, and efficient light emission. Unlike visible light LEDs, infrared LEDs emit light that is not visible to the human eye, making them suitable for applications that require invisible signaling or remote control.

How Does an Infrared LED 3mm Work?

An infrared LED 3mm operates based on the principle of electroluminescence. When an electric current passes through the LED, it excites the electrons within the semiconductor material, causing them to recombine and release energy in the form of light. In the case of an infrared LED, this energy is emitted as infrared light, which has a wavelength outside the visible spectrum. The 3mm size of the LED is determined by the physical dimensions of the semiconductor material and the encapsulation used. The small size makes it highly suitable for compact electronic devices, such as remote controls, wireless communication modules, and sensor applications.
