However, it was not until the early 2000s that high power infrared LED technology started to gain traction in various industries. The development of high power infrared LED technology was driven by the need for more efficient and powerful infrared light sources. In the early stages, these devices were limited by their low efficiency and short lifespan. However, advancements in materials science and semiconductor technology have led to significant improvements in the performance of high power infrared LEDs.

Technology of High Power Infrared LED

High power infrared LED technology involves the use of semiconductor materials that emit infrared light when an electric current is applied. The most commonly used materials for high power infrared LEDs are gallium arsenide (GaAs), gallium nitride (GaN), and indium gallium arsenide (InGaAs). The manufacturing process of high power infrared LEDs involves several steps, including epitaxial growth, wafer fabrication, and device assembly. Epitaxial growth is the process of depositing a thin layer of semiconductor material onto a substrate to create a single crystal structure. Wafer fabrication involves slicing the epitaxial layer into thin wafers, which are then processed to create the LED devices. Finally, device assembly involves mounting the LED chips onto a substrate and encapsulating them with a protective material. One of the key advantages of high power infrared LED technology is its ability to emit light at a specific wavelength, which allows for better control over the beam characteristics. High power infrared LEDs are available in various wavelengths, ranging from 780 nm to 3,000 nm, depending on the application.
