Introduction to Infrared LED Lamp Beads

What are Infrared LED Lamp Beads?

Infrared LED lamp beads, also known as infrared LED beads, are a type of semiconductor light-emitting diode (LED) that emits infrared light. They are widely used in various applications, including remote controls, surveillance systems, medical devices, and automotive lighting. Unlike visible light LEDs, infrared LED lamp beads emit light in the infrared spectrum, which is not visible to the human eye. Infrared LED lamp beads are typically made of gallium arsenide (GaAs) or gallium nitride (GaN) as the semiconductor material. These materials have high efficiency and can emit infrared light with a specific wavelength, which can range from 780nm to 950nm. The choice of material and wavelength depends on the specific application and the desired performance of the infrared LED lamp bead.

Working Principle of Infrared LED Lamp Beads

The working principle of infrared LED lamp beads is based on the semiconductor junction. When a forward voltage is applied to the diode, electrons and holes are injected into the junction. Due to the recombination of electrons and holes, energy is released in the form of light. In the case of infrared LED lamp beads, this energy is released in the infrared spectrum. The semiconductor material used in infrared LED lamp beads has a direct bandgap, which allows for efficient light emission in the infrared region. The bandgap of GaAs is around 1.42eV, corresponding to a wavelength of approximately 880nm, while the bandgap of GaN is around 3.4eV, corresponding to a wavelength of approximately 365nm. By adjusting the composition and structure of the semiconductor material, the wavelength of the emitted light can be tuned to meet the requirements of different applications.
