This article aims to provide an in-depth introduction to the photodiode LED industry, covering its definition, working principle, applications, market trends, and future prospects.

Definition and Working Principle of Photodiode LED

Photodiode LED is a semiconductor device that combines the functions of a photodiode and an LED. A photodiode is a semiconductor device that converts light into electrical current, while an LED (Light Emitting Diode) emits light when an electric current passes through it. The combination of these two technologies allows photodiode LED to perform both light detection and emission functions. The working principle of a photodiode LED is based on the photoelectric effect. When light enters the photodiode LED, it is absorbed by the semiconductor material, generating electron-hole pairs. These electron-hole pairs are separated by the internal electric field, resulting in a current flow. This current flow can be measured to determine the intensity of the incident light.
