Introduction

The term "strong IR LED" refers to an infrared light-emitting diode that emits intense infrared radiation. These devices have found wide applications in various industries, including consumer electronics, automotive, medical, and industrial automation. This article aims to provide a comprehensive introduction to the strong IR LED industry, covering its history, technology, applications, market trends, and future prospects.

History of Strong IR LED

Infrared light-emitting diodes (IR LEDs) have been in existence since the 1960s. However, it was not until the late 1970s that strong IR LEDs began to gain popularity. The development of these devices was driven by the increasing demand for infrared sensors and remote controls in consumer electronics. In the early 1980s, strong IR LEDs started to be used in automotive applications, such as reverse sensors and tire pressure monitoring systems. Since then, the industry has continued to grow, with new applications and technologies being developed regularly.

Technology of Strong IR LED

Strong IR LEDs are made of semiconductor materials, such as gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs). These materials have the ability to emit infrared radiation when an electric current is applied. The key factors that determine the performance of a strong IR LED include its wavelength, intensity, and efficiency. The wavelength of an IR LED determines the color of the infrared radiation it emits. Strong IR LEDs typically emit radiation in the near-infrared range, with wavelengths ranging from 780 nm to 1,100 nm. The intensity of an IR LED is measured in milliwatts (mW) and is a critical factor in its performance. High-intensity IR LEDs are essential for applications that require long-range detection, such as security systems and remote controls. Efficiency is another important factor in the performance of strong IR LEDs. The efficiency of an IR LED is measured in lumens per watt (LPW) and represents the amount of light emitted per unit of electrical power consumed. High-efficiency IR LEDs are desirable for applications that require long battery life or energy conservation.
