High Power IR LED: Revolutionizing the Future of Lighting and Sensing Technologies

Introduction to High Power IR LED

The high power IR LED (Infrared Light Emitting Diode) has emerged as a game-changer in the lighting and sensing technologies industry. These diodes are designed to emit intense infrared light, which has a wide range of applications across various sectors. The term "high power" refers to the ability of these LEDs to produce a higher intensity of light compared to traditional IR LEDs, making them more efficient and effective in their applications.

How High Power IR LEDs Work

High power IR LEDs work on the principle of semiconductor physics. When a forward bias is applied to the diode, electrons and holes recombine at the junction, releasing energy in the form of photons. In the case of IR LEDs, these photons are in the infrared spectrum, which is not visible to the human eye. The high power IR LEDs are engineered to maximize the number of photons emitted, thus providing a brighter and more intense infrared light.
