Introduction to Infrared LED High Power

1. Definition and Overview

Infrared LED high power refers to a type of LED that emits infrared light with high luminous intensity. It is widely used in various fields such as security, medical, automotive, and industrial applications. Compared with traditional infrared devices, infrared LED high power has the advantages of high efficiency, long life, and small size, which makes it more suitable for modern technology development.

2. Working Principle

The working principle of infrared LED high power is based on the semiconductor materials. When the forward voltage is applied to the semiconductor material, electrons and holes are generated, and the recombination of electrons and holes emits infrared light. The luminous intensity of the infrared LED high power is determined by the material properties, structure design, and manufacturing process.
