940nm infrared lamps, also known as near-infrared lamps, have gained significant attention in various industries due to their unique properties and applications. These lamps emit light at a wavelength of 940 nanometers, which falls within the near-infrared spectrum. This article aims to provide a comprehensive introduction to the 940nm infrared lamp industry, covering its technology, applications, market trends, and future prospects.

Technology of 940nm Infrared Lamps

The technology behind 940nm infrared lamps revolves around the use of semiconductor materials that can emit light at this specific wavelength. These lamps are typically made using gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs) as the active layer. The process involves growing these materials in a crystal structure, such as a gallium arsenide crystal, and then fabricating a diode structure that can generate light when an electric current is applied. The key to producing 940nm infrared lamps lies in the bandgap of the semiconductor material. The bandgap determines the color of the light emitted, with a smaller bandgap corresponding to a longer wavelength. By carefully selecting and engineering the semiconductor material, it is possible to achieve the desired 940nm wavelength for infrared light.
