This article aims to provide a comprehensive introduction to the power LED SMD industry, covering its history, technology, applications, and future prospects.

History of Power LED SMD

The concept of using LEDs for lighting dates back to the early 20th century. However, it was not until the late 1990s that power LED SMDs started gaining popularity. Initially, these devices were used in niche applications such as indicator lights and automotive lighting. As technology advanced, the efficiency and brightness of power LED SMDs improved, making them suitable for a wide range of lighting applications.

Technology of Power LED SMD

Power LED SMDs are made using a combination of semiconductor materials, primarily gallium nitride (GaN), silicon carbide (SiC), and aluminum nitride (AlN). These materials are chosen for their ability to emit light efficiently and withstand high temperatures. The manufacturing process involves epitaxial growth, wafer slicing, and die bonding. The epitaxial growth process involves depositing a thin layer of semiconductor material on a substrate. This layer is then sliced into individual dice, which are mounted on a substrate using die bonding techniques. The substrate is typically made of metal, ceramic, or plastic, depending on the application requirements.
