In this article, we will delve into the world of Through hole Multi-Color LED diodes, exploring their features, applications, and the technological advancements that have made them a popular choice in the industry.

Introduction to Through Hole Multi-Color LED Diodes

Through hole Multi-Color LED diodes are electronic components that emit light when an electric current passes through them. They are named "through hole" because their leads are inserted into holes in a printed circuit board (PCB) and then soldered in place. The "Multi-Color" aspect refers to their ability to emit light in various colors, typically red, green, blue, and yellow, by using different semiconductor materials.

Working Principle

The working principle of a Through hole Multi-Color LED diode is based on the photoelectric effect. When an electric current is applied to the diode, electrons and holes recombine in the semiconductor material, releasing energy in the form of photons. The color of the light emitted depends on the energy band gap of the semiconductor material used. For instance, red LEDs typically use aluminum gallium arsenide (AlGaAs), green LEDs use gallium nitride (GaN), blue LEDs use indium gallium nitride (InGaN), and yellow LEDs use a combination of these materials.
