Revolutionizing Lighting Technology: Unveiling the Advancements of High Power Violet LED

High power violet LED, also known as high power ultraviolet LED, is a type of light-emitting diode that emits light at a shorter wavelength than blue and violet LEDs. As the technology continues to advance, high power violet LEDs have gained significant attention in various industries due to their unique properties and wide range of applications. This article aims to provide an in-depth introduction to the high power violet LED industry, covering its development history, technology, applications, and future prospects.

Development History of High Power Violet LED

High power violet LED technology has a relatively short development history. The first violet LED was developed in the 1970s by Nick Holonyak Jr., a professor at the University of Illinois. However, due to the high cost and limited applications, the market demand for violet LEDs was not high at that time.

In the 1990s, with the development of semiconductor technology and the increasing demand for violet LEDs in the optical storage industry, the market demand for high power violet LEDs began to rise. During this period, companies such as Nichia, Cree, and Osram began to invest in the research and development of high power violet LEDs.

In the early 21st century, the rapid development of solid-state lighting technology and the increasing demand for high-power, high-efficiency, and high-quality light sources have further driven the development of high power violet LEDs. Today, high power violet LEDs have become an important part of the LED industry.

Technology of High Power Violet LED

The core technology of high power violet LED is the semiconductor material system. Currently, the most commonly used semiconductor materials for high power violet LEDs are gallium nitride (GaN), aluminum gallium nitride (AlGaN), and aluminum indium gallium nitride (AlInGaN).

The growth of semiconductor materials is a key step in the production of high power violet LEDs. The most commonly used method is the metal-organic chemical vapor deposition (MOCVD) method. This method can achieve high-quality and high-purity semiconductor materials, which is conducive to the improvement of LED performance.

In addition to the semiconductor material system, the structure design of the LED chip is also an important factor affecting the performance of high power violet LEDs. The commonly used structure design includes the multi-layer structure, the vertical structure, and the lateral structure. Among them, the multi-layer structure has higher efficiency and better thermal performance.
