Introduction to Infrared 850 LED Lamp

What is an Infrared 850 LED Lamp?

An infrared 850 LED lamp is a type of light-emitting diode (LED) that emits infrared radiation at a wavelength of 850 nanometers (nm). These lamps are widely used in various applications, including medical, industrial, and consumer electronics. Unlike visible light, infrared radiation is not visible to the human eye, making it an ideal choice for applications where light detection is required without the interference of visible light.

How Does an Infrared 850 LED Lamp Work?

An infrared 850 LED lamp works by converting electrical energy into infrared radiation through the process of electroluminescence. When an electric current passes through the semiconductor material within the LED, it generates heat, which excites the electrons in the material. As the electrons return to their ground state, they release energy in the form of photons, which are then emitted as infrared radiation. The key components of an infrared 850 LED lamp include: 1. Semiconductor material: The semiconductor material used in an infrared 850 LED lamp is typically gallium arsenide (GaAs) or indium gallium arsenide (InGaAs). These materials have a direct bandgap, which allows them to efficiently emit infrared radiation at a specific wavelength. 2. LED chip: The LED chip is the core component of the lamp, where the electroluminescence process takes place. It consists of a p-n junction, which is formed by doping the semiconductor material with impurities to create an electric field. 3. Lens: The lens is used to focus the emitted infrared radiation into a specific beam pattern. This helps to direct the light to the desired area and reduce wasted energy. 4. Heat sink: As infrared 850 LED lamps generate heat during operation, a heat sink is used to dissipate the excess heat and maintain the lamp's temperature within safe limits.
