Introduction to Infrared LED Light Technology

What is Infrared LED Light?

Infrared LED light, also known as infrared diode, is a type of light emitting diode (LED) that emits light in the infrared spectrum. Unlike visible light, infrared light is not visible to the naked eye, but it is detectable by special sensors and devices. Infrared LED light has a wide range of applications in various industries, including consumer electronics, medical devices, automotive, and industrial automation.

How Does Infrared LED Light Work?

Infrared LED light operates on the principle of electroluminescence, where an electric current is passed through a semiconductor material, causing it to emit light. The semiconductor material used in infrared LEDs is typically gallium arsenide (GaAs) or gallium nitride (GaN), which have high efficiency and emit light in the infrared range. The emitted light can be focused into a narrow beam or spread over a wider area, depending on the design of the LED.
