Unlike traditional IR LEDs, high power IR LEDs can produce significantly more light output, which is crucial for applications requiring strong infrared radiation.

What is a High Power IR LED?

A high power IR LED is a semiconductor device that emits infrared light at high intensities. It consists of a p-n junction, where electrons recombine with electron holes, releasing energy in the form of light. The term "high power" refers to the ability of the LED to produce a higher intensity of light compared to standard IR LEDs. This increased intensity is achieved through the use of advanced semiconductor materials and efficient heat dissipation techniques.
