Revolutionizing Heat Transfer: The Cutting-Edge Role of Infrared Emitter Tube in Modern Technology

Infrared emitter tube, also known as infrared LED, is a type of semiconductor device that emits infrared light. It is widely used in various fields such as consumer electronics, automotive, medical equipment, and industrial automation. This article will introduce the industry of infrared emitter tube, including its working principle, types, applications, market trends, and future development.

Working Principle of Infrared Emitter Tube

The infrared emitter tube is based on the principle of semiconductor physics. When a forward voltage is applied to the PN junction of the semiconductor material, electrons and holes are generated due to the injection of electrons from the N-type semiconductor to the P-type semiconductor. These electrons and holes recombine in the active layer of the semiconductor material, releasing energy in the form of infrared light.

Types of Infrared Emitter Tube

According to the wavelength of the emitted infrared light, infrared emitter tubes can be divided into three types: near-infrared, mid-infrared, and far-infrared. Near-infrared infrared emitter tubes have a wavelength range of 0.75-1.5μm, mid-infrared infrared emitter tubes have a wavelength range of 1.5-3μm, and far-infrared infrared emitter tubes have a wavelength range of 3-30μm. The materials used for infrared emitter tubes include gallium arsenide (GaAs), gallium phosphide (GaP), and indium antimonide (InSb), among others.
