This article delves into the world of infrared LED lamps, exploring their technology, applications, market trends, and future prospects.

Introduction to Infrared LED Lamps

Infrared LED lamps are a type of light-emitting diode (LED) that emits light in the infrared (IR) spectrum. Unlike visible light, infrared light is not visible to the human eye but can be detected by sensors and cameras. The primary advantage of infrared LED lamps is their ability to convert electrical energy into infrared light with high efficiency, making them a popular choice for various applications.

How Infrared LED Lamps Work

Infrared LED lamps work on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The semiconductor material used in these lamps is typically made of gallium arsenide (GaAs) or gallium nitride (GaN), which can emit infrared light when an electric current is applied. The process involves the recombination of electrons and holes within the semiconductor, resulting in the emission of photons in the infrared range.
