Introduction to High Power Infrared LED Technology

High power infrared LEDs are specialized semiconductor devices that emit infrared radiation at wavelengths between 780 nm and 3000 nm. They are designed to produce a higher intensity of light compared to conventional infrared LEDs, making them suitable for applications that require significant light output. These LEDs are based on the same principles as visible light LEDs but operate at a higher power level, which allows them to generate more heat and emit more light. The working principle of high power infrared LEDs involves the injection of electrical current into a semiconductor material, which generates heat and excites the electrons within the material. When the electrons recombine with the lattice of the semiconductor, they emit photons, which are then emitted as infrared radiation. The intensity of the emitted light is determined by the current flowing through the LED and the material's characteristics.
