Introduction to High-Power Infrared Lamp Beads

1. Definition and Overview

High-power infrared 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 fields, such as medical equipment, industrial automation, and home appliances. The main feature of high-power infrared lamp beads is their high luminous efficiency and long service life. In this article, we will introduce the basic knowledge, application fields, and development trends of high-power infrared lamp beads.

2. Working Principle

The working principle of high-power infrared lamp beads is based on the photoelectric effect of semiconductor materials. When the forward voltage is applied to the diode, electrons and holes are injected into the depletion region, and then recombine to emit photons. These photons are infrared light with a wavelength of 780nm to 3000nm. The high-power infrared lamp beads can emit more light than ordinary infrared lamps, which is mainly due to their high light-emitting efficiency and high power.
