Mini IR LED, or Mini Infrared Light Emitting Diode, has emerged as a significant technology in the field of optoelectronics. As the name suggests, these tiny LEDs emit infrared light, which has a wide range of applications across various industries. This article aims to provide an in-depth introduction to the mini IR LED industry, covering its technology, applications, market trends, and future prospects.

Technology of Mini IR LED

Mini IR LED technology is based on the principle of semiconductor physics. When a current is applied to a semiconductor material, it emits light. In the case of IR LEDs, the emitted light is in the infrared spectrum, which is not visible to the human eye. The size of a mini IR LED is typically less than 1mm in diameter, making it much smaller than traditional IR LEDs.

The mini IR LED is made of a semiconductor material, usually gallium nitride (GaN), which has excellent electrical and optical properties. The key to the mini IR LED's performance lies in its thin-film structure. The thin-film structure allows for a higher light output and a longer lifespan compared to traditional IR LEDs.
