Introduction to Infrared 850 LED Lamp

What is an Infrared 850 LED Lamp?

An Infrared 850 LED lamp is a specialized type of light emitting diode (LED) that emits infrared radiation at a wavelength of approximately 850 nanometers. Unlike visible light, infrared radiation is not detectable by the human eye, making it ideal for applications where stealth or covert lighting is required. These lamps are widely used in various industries, including medical, automotive, security, and industrial settings.

How Does an Infrared 850 LED Lamp Work?

Infrared 850 LED lamps operate 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 lamps is typically gallium arsenide (GaAs) or indium gallium arsenide (InGaAs), which are capable of emitting infrared radiation at the desired wavelength. When the current flows through the semiconductor, it excites the electrons, causing them to recombine with electron holes, releasing energy in the form of photons. The key components of an Infrared 850 LED lamp include the LED chip, a lens or reflector to focus the light, and a heat sink to dissipate the heat generated during operation. The LED chip is mounted on a substrate, which is then attached to the heat sink. The lens or reflector is designed to direct the infrared radiation in a specific direction, maximizing the efficiency of the lamp.
