Photodiode LED, a combination of photodiode and LED technologies, has become a significant player in the field of optoelectronics. This article aims to provide an in-depth introduction to the photodiode LED industry, covering its working principle, applications, market trends, and future prospects.

Introduction to Photodiode LED

Photodiode LED is a device that integrates the functions of both photodiode and LED. A photodiode is a semiconductor device that converts light into electrical current, while an LED (Light Emitting Diode) emits light when current passes through it. The combination of these two technologies enables photodiode LED to perform dual functions, making it highly versatile in various applications.

Working Principle of Photodiode LED

The working principle of photodiode LED is based on the photoelectric effect. When light shines on the photodiode LED, it generates an electrical current. The intensity of the current is proportional to the intensity of the light. This property allows photodiode LED to be used as a light sensor. At the same time, when a voltage is applied to the photodiode LED, it emits light, making it a light source. The light emitted by the LED has a specific wavelength, which can be tuned by adjusting the composition of the semiconductor materials.
