In this article, we’ll delve into the fascinating world of miniature LEDs and explore their applications, benefits, and the technology behind them.
What are LEDs?
Before we dive into the smallest LED light, let’s first understand what LEDs are. LEDs are semiconductor devices that emit light when an electric current passes through them. They consist of two types of materials, p-type (positive) and n-type (negative), which are combined to form a p-n junction. When a voltage is applied to the p-n junction, electrons flow from the n-type material to the p-type material, releasing energy in the form of light.
How are LEDs Made?
LEDs are made using a process called epitaxy, where layers of semiconductor material are deposited onto a substrate. The substrate is typically made of silicon carbide or sapphire, and the semiconductor material is usually gallium nitride (GaN) or silicon carbide (SiC). The layers are carefully controlled to create the desired p-n junction, which determines the color and efficiency of the LED.
