Mini IR LED, also known as Mini Infrared LED, has become an essential component in the field of optoelectronics. As a type of infrared emitting diode, it is widely used in various applications such as consumer electronics, automotive, and industrial fields. This article aims to provide an in-depth introduction to the mini IR LED industry, covering its definition, working principle, market trends, and future prospects.

Definition and Working Principle of Mini IR LED

Mini IR LED is a compact and high-efficiency infrared emitting diode with a small size and low power consumption. It emits infrared light with a wavelength between 700nm to 1000nm, which is invisible to the human eye. The working principle of mini IR LED is based on the photoelectric effect, where electrons are injected into the conduction band when the diode is forward biased, resulting in the emission of infrared light.

Mini IR LED is typically made of gallium arsenide (GaAs) or its alloys, which have excellent optoelectronic properties. The size of the LED can range from a few millimeters to a few tens of micrometers, depending on the application requirements. The key advantages of mini IR LED include high brightness, long lifespan, and low cost.
