Introduction to Infrared LED Lamp Beads

1. Definition and Basic Concept

Infrared LED lamp beads, also known as infrared diode lamps, are a type of semiconductor light-emitting device. They emit infrared light through a diode. The infrared light is invisible to the human eye, but can be detected by special sensors or devices. These lamp beads have wide application in various fields, such as remote control, night vision, and infrared communication.

2. Working Principle

The working principle of infrared LED lamp beads is based on the photoelectric effect. When the forward voltage is applied to the diode, electrons and holes are recombined, releasing energy in the form of photons. These photons are emitted in the infrared spectrum, which is invisible to the human eye. The intensity of the emitted light is determined by the material and structure of the diode.

3. Types of Infrared LED Lamp Beads

According to the emission spectrum, infrared LED lamp beads can be divided into three types: near-infrared, mid-infrared, and far-infrared. Near-infrared LED lamp beads have a shorter wavelength and higher intensity, which are commonly used in remote control and communication. Mid-infrared LED lamp beads have a longer wavelength and lower intensity, suitable for night vision and thermal imaging. Far-infrared LED lamp beads have the longest wavelength and lowest intensity, mainly used in infrared heating.

4. Materials and Structure

The main materials of infrared LED lamp beads include gallium arsenide (GaAs), gallium phosphide (GaP), and indium antimonide (InSb). These materials have good optical and electrical properties, which can effectively emit infrared light. The structure of infrared LED lamp beads generally includes a p-n junction, a package, and an optical lens. The p-n junction is the core part of the diode, which emits infrared light. The package is used to protect the diode and improve its heat dissipation performance. The optical lens can focus the emitted light, improve the light intensity, and increase the distance of the light transmission.
