LED infrarrojo, or infrared LED, has become an indispensable component in various industries due to its excellent performance and wide application prospects. This article will introduce the LED infrared industry, covering its definition, development history, market trends, and future prospects.

Definition and Working Principle of LED Infrared

LED infrared refers to an infrared light-emitting diode, which emits infrared light with a wavelength ranging from 780nm to 3000nm. It has the characteristics of high efficiency, low power consumption, and long service life. The working principle of LED infrared is based on the injection of electrons and holes into the semiconductor material under forward bias. When electrons and holes recombine, infrared photons are emitted.

Development History of LED Infrared

The development of LED infrared technology can be traced back to the 1960s when the first infrared LED was developed. At that time, the infrared LED was mainly used in military and industrial fields. With the continuous advancement of technology, the application range of LED infrared has been expanding, and it has gradually entered the civilian market. In the 1970s, the development of LED infrared technology was relatively slow, and its market was not yet formed. However, in the 1980s, with the rapid development of the semiconductor industry, the cost of LED infrared components decreased significantly, which promoted the popularization of its application in the civilian market. In the 1990s, the application of LED infrared technology in consumer electronics, such as remote controls, became more widespread. At the same time, the research and development of LED infrared technology were also accelerated, and new products and applications emerged one after another. In the 21st century, the development of LED infrared technology has been entering a new stage. With the continuous improvement of performance and the expansion of application fields, LED infrared has become an important part of the intelligent era.
