Introduction to LED IR 940nm

LED IR 940nm refers to an infrared LED (Light Emitting Diode) that emits light at a wavelength of 940 nanometers. This type of LED is designed to emit infrared radiation, which is invisible to the human eye. The 940nm wavelength falls within the near-infrared spectrum, making it ideal for various applications where invisible light detection is required.

How LED IR 940nm Works

LED IR 940nm operates on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The semiconductor material used in these LEDs is typically made of gallium arsenide (GaAs) or similar compounds. When an electric current is applied, electrons and holes recombine in the semiconductor, releasing energy in the form of photons at the 940nm wavelength.

The LED IR 940nm emits a continuous wave of infrared light, which can be detected by various sensors and cameras designed to capture near-infrared radiation. This makes it a versatile tool for applications that require invisible light detection, such as night vision devices, thermal imaging cameras, and motion sensors.
