IR LED 950nm, also known as infrared LED with a peak emission wavelength of 950 nanometers, has become a significant player in the field of infrared technology. These LEDs are designed to emit infrared light at a specific wavelength, making them ideal for a wide range of applications, from industrial automation to consumer electronics. This article delves into the world of 950nm IR LEDs, exploring their technology, applications, and the industry trends that are shaping their future.

Introduction to IR LED 950nm

IR LED 950nm refers to a type of light-emitting diode (LED) that emits infrared radiation at a wavelength of approximately 950 nanometers. This falls within the near-infrared spectrum, which is just beyond the visible light range. The 950nm wavelength is particularly useful for applications that require long-range detection or communication, as it can penetrate certain materials and be detected over greater distances.

Working Principle of IR LED 950nm

Like other LEDs, IR LED 950nm operates on the principle of electroluminescence. When an electric current passes through a semiconductor material, it excites electrons, causing them to move from the valence band to the conduction band. As these electrons recombine with holes in the valence band, they release energy in the form of photons. In the case of 950nm IR LEDs, these photons are in the infrared part of the electromagnetic spectrum.

The semiconductor material used in 950nm IR LEDs is typically made of gallium arsenide (GaAs) or a similar compound, which has the ability to emit infrared light at the desired wavelength. The quality of the semiconductor material and the design of the LED structure play a crucial role in determining the efficiency and performance of the LED.
