Revolutionizing Infrared Detection: The Emerging Role of IR Black LED Technology

Introduction to IR Black LED

What is an IR Black LED?

An IR Black LED, short for Infrared Black Light Emitting Diode, is a type of LED that emits infrared light at a specific wavelength. Unlike traditional LEDs that emit visible light, IR Black LEDs are designed to emit light in the infrared spectrum, which is not visible to the human eye. These LEDs are widely used in various applications, including security systems, remote controls, and medical devices.

Working Principle of IR Black LED

The working principle of an IR Black LED is based on the semiconductor material, typically gallium arsenide (GaAs), which emits infrared light when an electric current passes through it. The infrared light emitted by the LED is in the range of 780 to 1000 nanometers, which is beyond the visible spectrum. The black color of the LED is achieved by coating the semiconductor material with a black phosphorus layer, which absorbs visible light and reflects infrared light.
