Strong IR LED, or Infrared Light Emitting Diode, has become an indispensable component in various industries due to its unique properties and wide range of applications. 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

The concept of the LED was first introduced in the 1920s, but it was not until the 1960s that the first practical LED was developed. The early LEDs were primarily used for indicator lights and displays. However, with the advancement of technology, the infrared (IR) spectrum was discovered to have a wide range of applications, leading to the development of IR LEDs.

Strong IR LEDs, in particular, have seen significant growth in the past few decades. This growth can be attributed to the increasing demand for long-range communication, remote control, and security systems. The first strong IR LED was developed in the late 1970s, and since then, the technology has evolved rapidly, with improvements in efficiency, lifespan, and cost-effectiveness.

Technology of Strong IR LED

Strong IR LEDs are semiconductor devices that emit infrared light when an electric current is applied. The basic structure of a strong IR LED consists of a p-n junction, where the p-type material has an excess of positively charged carriers (holes), and the n-type material has an excess of negatively charged carriers (electrons).

When an electric current is applied, electrons from the n-type material are injected into the p-type material, and holes from the p-type material are injected into the n-type material. As these carriers recombine, they release energy in the form of photons, which are emitted as infrared light.

The efficiency of a strong IR LED is determined by the quality of the semiconductor material, the design of the p-n junction, and the manufacturing process. Advances in materials science and semiconductor technology have led to the development of high-efficiency, long-life strong IR LEDs.
