High power infrared LED, or High Power Infrared Light Emitting Diode, has emerged as a crucial technology in various industries due to its ability to emit intense infrared light. These LEDs are designed to provide high luminous intensity and efficiency, making them ideal for applications requiring long-range detection, communication, and illumination. This article delves into the world of high power infrared LEDs, exploring their technology, applications, market trends, and future prospects.

Introduction to High Power Infrared LEDs

High power infrared LEDs are semiconductor devices that emit light in the infrared spectrum, typically between 700 nm and 3000 nm. Unlike visible light LEDs, which emit light that is visible to the human eye, infrared LEDs emit light that is not visible. This invisible light is widely used in applications where visibility is not required, but the detection or transmission of signals is crucial.

Working Principle

The working principle of high power infrared LEDs is based on the semiconductor junction. When a forward voltage is applied to the junction, electrons and holes are injected into the active region. These charge carriers recombine, releasing energy in the form of photons. The longer the wavelength, the lower the energy of the photons, which is why infrared LEDs emit light at a lower intensity than visible light LEDs.
