Working Principle of Photodiode LED

Photodiode LED is a device that combines the photoelectric effect of photodiodes and the light-emitting effect of LEDs. It consists of a photodiode and an LED, which are encapsulated together in a single package. When light enters the photodiode, it generates an electric current, which can be used to detect the light intensity. At the same time, the LED emits light, which can be used for various applications such as optical communication, sensing, and display. The working principle of Photodiode LED can be described as follows: 1. Light enters the photodiode and generates an electric current. 2. The electric current is amplified and processed by the circuit. 3. The processed signal is transmitted to the LED, which emits light with a certain intensity. 4. The emitted light can be used for various applications.
