Introduction

The infrared emitter tube LED, also known as an infrared LED, is a semiconductor device that emits infrared radiation when an electric current is applied. It has become an indispensable component in various fields, such as remote control, communication, and security systems. This article will provide an in-depth introduction to the infrared emitter tube LED, covering its working principle, types, applications, and market trends.

Working Principle of Infrared Emitter Tube LED

The infrared emitter tube LED is based on the photoelectric effect of semiconductor materials. When an electric current is applied to the semiconductor material, electrons and holes are generated, and when they recombine, infrared radiation is emitted. The wavelength of the emitted infrared radiation is determined by the energy band gap of the semiconductor material. The longer the wavelength, the lower the energy band gap, and vice versa. The typical semiconductor materials used in infrared emitter tube LEDs include gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs). These materials have a suitable energy band gap to emit infrared radiation within the 700nm to 1400nm range, which is widely used in various applications.

Types of Infrared Emitter Tube LED

Infrared emitter tube LEDs can be classified into several types based on their structure, packaging, and application requirements. 1. Structure: In terms of structure, infrared emitter tube LEDs can be divided into single-element, double-element, and array-type. Single-element infrared emitter tube LEDs have a simple structure and are suitable for low-power applications. Double-element infrared emitter tube LEDs have a more complex structure and can achieve higher output power. Array-type infrared emitter tube LEDs have multiple elements in a matrix arrangement, which can provide a wider beam angle and higher output power. 2. Packaging: In terms of packaging, infrared emitter tube LEDs can be divided into through-hole and surface mount types. Through-hole infrared emitter tube LEDs are suitable for high-power applications, while surface mount infrared emitter tube LEDs are more suitable for low-power applications due to their compact size. 3. Application requirements: According to the application requirements, infrared emitter tube LEDs can be divided into general-purpose, high-power, and high-speed types. General-purpose infrared emitter tube LEDs are suitable for general applications, while high-power and high-speed types are used in high-power and high-speed applications, respectively.
