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 specific wavelength of 850 nanometers. These lamps are designed to provide a focused and concentrated beam of infrared light, which is invisible to the human eye. The 850 nm wavelength falls within the near-infrared spectrum, making it ideal for various applications where invisible light is required, such as in medical, industrial, and security sectors.

How Does an Infrared 850 LED Lamp Work?

Infrared 850 LED lamps operate on the principle of the光电效应, where an electrical current passes through a semiconductor material, causing electrons to be excited and emit photons. In the case of an infrared 850 LED, these photons are in the form of infrared radiation. The LED chip used in these lamps is made of materials like gallium arsenide (GaAs) or indium gallium arsenide (InGaAs), which are highly efficient at emitting infrared light at the desired wavelength. The LED lamp consists of several key components: 1. LED Chip: The core of the lamp, which emits the infrared light. 2. Lens: A lens is used to focus the emitted light into a narrow beam, ensuring that the infrared radiation is directed where it is needed. 3. Driver: An electrical driver supplies the appropriate current and voltage to the LED chip, ensuring optimal performance and longevity. 4. Heat Sink: To dissipate the heat generated by the LED chip, a heat sink is often integrated into the lamp design.
