Introduction to Infrared LED Lamp Beads

What are Infrared LED Lamp Beads?

Infrared LED lamp beads, also known as infrared LEDs, are a type of light-emitting diode that emits infrared light. Unlike visible light, infrared light is not visible to the human eye. These lamp beads are widely used in various applications due to their unique properties and benefits. In this article, we will explore the uses, advantages, and future trends of infrared LED lamp beads in the industry.

How Do Infrared LED Lamp Beads Work?

Infrared LED lamp beads work on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The semiconductor material used in these lamp beads is typically made of gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). When an electric current is applied, the electrons and holes in the semiconductor recombine, releasing energy in the form of infrared light. The color of the infrared light emitted by these lamp beads can vary depending on the material composition and manufacturing process. Common colors include near-infrared (NIR), mid-infrared (MIR), and far-infrared (FIR). Near-infrared light has a wavelength range of 700 to 1400 nanometers, mid-infrared light ranges from 1400 to 3000 nanometers, and far-infrared light extends beyond 3000 nanometers.
