Introduction to High Power Infrared LED Diodes

High power infrared LED diodes are semiconductor devices that emit infrared light at a high intensity. They are designed to produce a greater amount of light than standard infrared LEDs, making them ideal for applications that require significant light output. These diodes are typically made using gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs) materials and are available in various wavelengths, from near-infrared to mid-infrared.

How High Power Infrared LED Diodes Work

The operation of high power infrared LED diodes is based on the principle of the electroluminescent effect. When an electric current passes through the semiconductor material, it excites electrons, which then recombine with holes, emitting photons in the process. The energy of these photons determines the color and wavelength of the light emitted. In the case of infrared LEDs, the photons have wavelengths beyond the visible spectrum, making them invisible to the human eye.

The efficiency of high power infrared LED diodes is crucial for their applications. These diodes are designed to have high luminous efficacy, which is the ratio of the emitted light to the electrical power consumed. Modern high power infrared LED diodes can achieve luminous efficacies of up to 100 lumens per watt, making them highly efficient compared to traditional lighting sources.
