Infrared 940nm lamp, as a type of infrared radiation source, has been widely used in various fields due to its excellent performance and wide range of applications. This article will introduce the basic concepts, working principles, application fields, and future development trends of infrared 940nm lamps, aiming to provide readers with a comprehensive understanding of this product.

Basic Concepts of Infrared 940nm Lamp

The infrared 940nm lamp is a kind of infrared light-emitting device that emits infrared radiation with a wavelength of 940nm. It belongs to the near-infrared spectrum, which is close to the red light in the visible spectrum. The light emitted by the infrared 940nm lamp is invisible to the naked eye, so it is often used in fields that require invisible light. Infrared 940nm lamps are usually made of semiconductor materials, such as gallium arsenide (GaAs), indium gallium arsenide (InGaAs), and indium gallium phosphide (InGaP), which can efficiently convert electrical energy into light energy.

Working Principle of Infrared 940nm Lamp

The working principle of the infrared 940nm lamp is based on the photoelectric effect. When the semiconductor material is excited by an external electric field, electrons and holes are generated, and then recombine. During the recombination process, a certain amount of energy is released, which is converted into light energy. The specific process is as follows: 1. When the voltage is applied to the semiconductor material, electrons are injected into the conduction band, and holes are generated in the valence band. 2. The electrons and holes move towards the p-n junction and recombine. 3. The recombination process releases energy, which is converted into light energy with a wavelength of 940nm.
