IR LED 950nm, or Infrared Light Emitting Diode with a peak emission wavelength of 950nm, has become a significant component in various industries due to its unique properties and applications. This article aims to provide an in-depth introduction to the 950nm IR LED industry, covering its history, technology, applications, market trends, and future prospects.

History and Development

The concept of infrared light emitting diodes (IR LEDs) dates back to the early 20th century when the first semiconductor diodes were developed. However, it was not until the late 1950s that the first practical IR LED was invented by Nick Holonyak at General Electric. Since then, the technology has evolved significantly, with the peak emission wavelength of IR LEDs extending to 950nm.

As the technology matured, IR LEDs with 950nm emission became more popular due to their longer wavelength, which offers several advantages over shorter-wavelength IR LEDs. These advantages include better penetration through materials, reduced interference from ambient light, and lower power consumption.

Technology and Manufacturing

IR LED 950nm technology involves the use of semiconductor materials with specific bandgap energies to emit infrared light at 950nm. Common materials used in the manufacturing of 950nm IR LEDs include AlInGaAs (Aluminum Gallium Indium Arsenide) and InGaAsP (Indium Gallium Arsenide Phosphide).

The manufacturing process of 950nm IR LEDs involves several steps, including epitaxial growth, wafer fabrication, and device assembly. Epitaxial growth is the process of depositing a thin layer of semiconductor material on a substrate to create a desired structure. Wafer fabrication involves slicing the epitaxial wafer into individual chips and then dicing them into smaller pieces. Finally, device assembly involves mounting the chips onto a substrate and bonding them to a lead frame for electrical connection.

Applications

IR LED 950nm technology has found applications in various industries, including consumer electronics, automotive, medical, and industrial sectors.

In consumer electronics, 950nm IR LEDs are commonly used in remote controls, infrared sensors, and night vision devices. Their longer wavelength allows for better signal transmission and reception, resulting in improved performance.
