LED infrarrojo, or infrared LED, is a type of light-emitting diode that emits infrared light. As technology advances, the applications of infrared LED have expanded significantly in various fields, such as consumer electronics, automotive, medical, and industrial sectors. This article will provide an overview of the infrared LED industry, covering its development history, technology, market trends, and future prospects.

Development History of Infrared LED

The development of infrared LED technology dates back to the early 1960s when the first infrared LED was created. Initially, these devices were used in simple applications such as remote controls and security systems. Over the years, advancements in semiconductor materials and manufacturing processes have led to the development of high-efficiency, high-brightness infrared LEDs.

During the 1980s, the infrared LED market began to grow rapidly, driven by the increasing demand for consumer electronics, such as remote controls, mobile phones, and digital cameras. The introduction of surface mount technology (SMT) in the 1990s further facilitated the integration of infrared LEDs into various electronic devices.

In the early 2000s, the infrared LED industry continued to evolve with the development of new materials and processes. The introduction of AlInGaAs (Aluminum Gallium Indium Arsenide) and InGaAsP (Indium Gallium Arsenide Phosphide) as active layers improved the performance of infrared LEDs, enabling them to be used in more sophisticated applications, such as optical communication and infrared sensors.

Technology of Infrared LED

Infrared LED technology involves the use of semiconductor materials to create aPN junction, which emits infrared light when an electric current is applied. The key parameters that determine the performance of an infrared LED include wavelength, intensity, and viewing angle.

Wavelength: Infrared LEDs are categorized based on their emission wavelengths, which range from 780nm to 3000nm. Short-wavelength infrared LEDs (780nm-1000nm) are commonly used in consumer electronics, while long-wavelength infrared LEDs (1000nm-3000nm) are preferred for industrial applications.

Intensity: The intensity of an infrared LED is determined by the amount of light emitted per unit area. High-intensity infrared LEDs are essential for applications requiring long-distance transmission, such as optical communication and remote sensing.

Viewing Angle: The viewing angle of an infrared LED refers to the range of angles from which the light can be detected. A narrow viewing angle is suitable for applications requiring focused illumination, while a wide viewing angle is more appropriate for applications requiring broader coverage.
