What is a High Power Infrared LED Diode?

A high power infrared LED diode is a semiconductor device that emits infrared light when an electric current is applied. Unlike traditional light-emitting diodes (LEDs), which emit visible light, infrared LEDs emit light in the infrared spectrum, which is not visible to the human eye. High power infrared LED diodes are designed to emit a higher intensity of light, making them suitable for applications that require long-range detection and illumination.

Working Principle

The working principle of a high power infrared LED diode is based on the semiconductor junction. When an electric current is applied to the diode, electrons and holes are injected into the junction. As these charge carriers recombine, they release energy in the form of photons. In the case of infrared LEDs, the photons emitted fall within the infrared spectrum, which has a wavelength range of 700 to 1,000 nanometers. The key to achieving high power output in infrared LED diodes lies in the design and material composition of the semiconductor. High-quality materials, such as gallium arsenide (GaAs) and indium gallium arsenide (InGaAs), are used to create the active region of the diode. These materials have a direct bandgap, which allows for efficient light emission. Additionally, the use of advanced epitaxial growth techniques and packaging technologies contributes to the high power output of these diodes.
