Introduction to High Power IR LED 940nm

High power IR LED 940nm refers to an infrared light-emitting diode that operates at a wavelength of 940 nanometers. Unlike visible light, which is within the range of 380 to 780 nanometers, infrared light is beyond the visible spectrum and is not detectable by the human eye. However, it plays a significant role in numerous technologies, including remote controls, surveillance systems, medical devices, and automotive applications.

How High Power IR LED 940nm Works

High power IR LED 940nm operates on the principle of the semiconductor diode. When an electric current is applied to the diode, electrons recombine with electron holes, releasing energy in the form of photons. In the case of IR LEDs, these photons have a wavelength of 940nm, making them infrared light.

The high power aspect of these LEDs refers to their ability to emit a significant amount of light at the 940nm wavelength. This is achieved by using advanced semiconductor materials and optimizing the design of the LED to enhance its light output. High power IR LED 940nm devices can produce up to 100 milliwatts or more, which is several times more than standard IR LEDs.
