Introduction to Infrared LED 4mm

What is an Infrared LED 4mm?

An infrared LED 4mm, also known as an infrared emitting diode, is a type of semiconductor device that emits infrared light when an electric current is applied to it. The "4mm" refers to the diameter of the LED, which is 4 millimeters. These LEDs are widely used in various applications due to their compact size, low power consumption, and efficient infrared emission. Infrared LEDs work on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The emitted light is in the infrared spectrum, which is not visible to the human eye. However, it can be detected by various sensors and devices, making it useful in numerous applications.

Applications of Infrared LED 4mm

Infrared LED 4mm find extensive use in various industries and applications. Some of the common applications include: 1.
