Infrared 850nm lamps are a specialized type of lighting technology that emit light at a specific wavelength of 850 nanometers. These lamps have found wide applications in various industries due to their unique properties and advantages. This article aims to provide an in-depth introduction to the infrared 850nm lamp industry, covering its history, technology, applications, and future prospects.

History of Infrared 850nm Lamps

The concept of infrared lighting dates back to the early 20th century when scientists began to explore the properties of infrared radiation. Infrared 850nm lamps, however, became more prominent in the late 20th century as advancements in semiconductor technology made it possible to produce light-emitting diodes (LEDs) that could emit light at this specific wavelength. The first infrared 850nm lamps were developed for military and aerospace applications, where the ability to detect and track objects in the dark was crucial. Over time, the technology has evolved, and the lamps have found their way into various commercial and industrial sectors.

Technology Behind Infrared 850nm Lamps

Infrared 850nm lamps are typically made using infrared LEDs, which are semiconductor devices that emit light when an electric current passes through them. The key to producing light at 850nm lies in the semiconductor material used in the LED, which must have the right energy bandgap to emit light at this specific wavelength. The semiconductor material commonly used for infrared 850nm LEDs is aluminum gallium arsenide (AlGaAs). When an electric current is applied, electrons and holes recombine within the material, releasing energy in the form of photons at 850nm. The efficiency and lifespan of the lamp depend on the quality of the semiconductor material and the design of the LED.
