High output IR LED, or Infrared Light Emitting Diode, has emerged as a crucial component in various industries due to its ability to emit intense infrared light. This article aims to provide an in-depth introduction to the high output IR LED industry, covering its history, technology, applications, market trends, and future prospects.

History of High Output IR LED

The concept of the infrared LED dates back to the early 20th century. In 1908, Henry Joseph Round, an English physicist, discovered that certain materials could emit infrared radiation when an electric current was applied to them. This discovery laid the foundation for the development of infrared LEDs. Over the years, the technology has evolved significantly, and high output IR LEDs have become more efficient and reliable.

Technology of High Output IR LED

High output IR LEDs are made of semiconductor materials, typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). These materials have a direct bandgap, which allows them to emit infrared light efficiently. The key to achieving high output lies in the design and fabrication of the LED chip. Several factors contribute to the high output of these LEDs, including:
