Optimized IR LED Source: The Ultimate Guide

IR LED source, short for Infrared Light Emitting Diode source, has become an indispensable component in various industries due to its excellent performance and wide application. This article will introduce the industry of IR LED sources, including their basic concepts, types, applications, and future development trends.

Basic Concepts of IR LED Source

Infrared Light Emitting Diode, or IR LED, is a semiconductor device that emits infrared light when an electric current passes through it. The wavelength of the emitted light ranges from 700 nm to 3000 nm, which is beyond the visible light range of the human eye. IR LED sources are widely used in various fields due to their low power consumption, high efficiency, and excellent heat dissipation performance.

Types of IR LED Sources

IR LED sources can be divided into several types according to their materials, structures, and applications.

Material-based Classification

1. Infrared emitting diodes with gallium arsenide (GaAs) as the main material: These diodes have excellent performance in terms of brightness, lifespan, and stability, and are widely used in industrial applications.

2. Infrared emitting diodes with gallium nitride (GaN) as the main material: GaN-based IR LED sources have higher luminous efficiency and wider spectral range than GaAs-based sources, and are suitable for applications such as automotive, medical, and consumer electronics.

3. Infrared emitting diodes with carbon-based materials: Carbon-based IR LED sources have excellent biocompatibility and can be used in medical and health fields.

Structure-based Classification

1. Planar structure: This structure has simple manufacturing processes and low cost, but the luminous efficiency is relatively low.

2. Collimating structure: This structure can improve the luminous efficiency and uniformity of the IR LED source, but the manufacturing process is more complex.

3. Micro-structured structure: This structure can optimize the light distribution and improve the luminous efficiency of the IR LED source, but the cost is higher.
