Infrared LED patch, also known as an infrared emitting diode patch, is a compact and efficient light-emitting device widely used in various applications. With the rapid development of technology, infrared LED patches have become an indispensable part of modern life. This article will introduce the basic concepts, applications, and future trends of infrared LED patches.

Basic Concepts of Infrared LED Patch

Infrared LED patch is a type of light-emitting diode (LED) that emits infrared light. It is composed of a semiconductor material, usually gallium arsenide (GaAs) or gallium phosphide (GaP), which has a direct bandgap. When an electric current is applied to the semiconductor material, electrons and holes recombine, releasing energy in the form of infrared light.

Infrared LED patches have several advantages over traditional light sources. Firstly, they have a high efficiency, converting more than 80% of the electrical energy into light. Secondly, they have a long lifespan, typically more than 50,000 hours. Thirdly, they have a compact size, making them suitable for various applications where space is limited.

Applications of Infrared LED Patch

Infrared LED patches have a wide range of applications in various industries. The following are some of the most common applications:
