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). Unlike visible light, infrared radiation is not visible to the human eye, making it ideal for applications where light detection or heating is required without the need for visible illumination. These lamps are widely used in various industries, including medical, automotive, security, and consumer electronics.

How Does an Infrared 850 LED Lamp Work?

An Infrared 850 LED lamp operates on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. In the case of an Infrared 850 LED lamp, the semiconductor material is typically made of gallium arsenide (GaAs) or indium gallium arsenide (InGaAs). When an electric current is applied, the electrons and holes in the semiconductor recombine, releasing energy in the form of infrared radiation. The key components of an Infrared 850 LED lamp include the LED chip, a phosphor coating, and a lens. The LED chip is the semiconductor material that emits the infrared radiation. The phosphor coating is applied to the LED chip to convert a portion of the infrared radiation into visible light, which can be useful in certain applications. The lens is used to focus the emitted light into a specific beam pattern.

Applications of Infrared 850 LED Lamps

Infrared 850 LED lamps have a wide range of applications due to their ability to emit infrared radiation without visible light. Some of the most common applications include: 1.
