Introduction to IR LED Module

What is an IR LED Module?

An IR LED module, short for Infrared Light Emitting Diode module, is a compact electronic device that emits infrared light. It consists of an infrared LED chip, a lens, and a housing. IR LED modules are widely used in various applications, including remote controls, security systems, communication systems, and more. They offer several advantages, such as compact size, low power consumption, and high efficiency.

How Does an IR LED Module Work?

An IR LED module works on the principle of electroluminescence. When an electric current passes through the LED chip, it emits infrared light. The lens focuses the light into a narrow beam, making it easier to detect and control. The infrared light emitted by the module is in the invisible spectrum, which means it cannot be seen by the naked eye. However, it can be detected by IR sensors and cameras.
