Introduction to Super Bright IR LEDs

Super bright IR LEDs are semiconductor devices that emit infrared light when an electric current passes through them. Unlike visible light LEDs, which produce light in the visible spectrum, IR LEDs emit light in the infrared region, which is beyond the range of human vision. The key advantages of super bright IR LEDs include their high brightness, low power consumption, and compact size. The working principle of an IR LED is based on the quantum mechanical effect. When an electric current is applied to the LED, electrons and holes are injected into the semiconductor material. As these electrons and holes recombine, they release energy in the form of photons. In the case of IR LEDs, the energy released corresponds to the infrared region of the electromagnetic spectrum.
