LED violet lamp, also known as violet LED, is a type of light-emitting diode that emits light at a shorter wavelength than blue LEDs, which is around 380-450 nanometers. As the shortest wavelength in the visible spectrum, violet light has attracted considerable attention in various fields, such as display, medical, and security. This article aims to introduce the industry of LED violet lamps, covering their history, applications, technology, and market trends.

History of LED Violet Lamp

LED violet lamp technology has a relatively short history. In the 1960s, scientists discovered that certain materials could emit violet light when electrically excited. However, due to the limitations of materials and manufacturing technology at that time, the development of violet LED lamps was slow. It was not until the 1990s that the development of violet LED lamps gained momentum, mainly driven by the demand for high-definition displays and laser applications. In the early 2000s, the research and development of violet LED lamps continued to advance, with the introduction of new materials and manufacturing technologies. In 2001, Nichia Corporation, a Japanese company, successfully developed the world's first commercial violet LED lamp, which marked the beginning of the commercialization of violet LED lamps.

Applications of LED Violet Lamp

LED violet lamps have a wide range of applications due to their unique optical properties. The following are some typical applications: 1. Display: Violet LED lamps are used in high-definition displays, such as liquid crystal displays (LCDs) and organic light-emitting diodes (OLEDs). The short wavelength of violet light enables the production of high-resolution and high-contrast displays. 2. Medical: Violet light has strong杀菌 (bactericidal) properties. LED violet lamps are used in medical fields, such as sterilization and wound healing. In addition, violet light can also be used to treat skin diseases and promote hair growth. 3. Security: Violet LED lamps are used in security systems, such as barcode scanners and holographic cards. The short wavelength of violet light makes it difficult to forge, ensuring the security of the system. 4. Optical communication: Violet LED lamps can be used in optical communication systems, such as fiber optic communication. The high frequency of violet light allows for higher data transmission rates. 5. Laser applications: Violet LED lamps can be used as laser sources in various applications, such as laser engraving and laser cutting.

Technology of LED Violet Lamp

The technology of LED violet lamp mainly includes the following aspects: 1. Material: The key to the development of violet LED lamps is the selection of suitable materials. Currently, gallium nitride (GaN) is the most commonly used material for violet LED lamps. By adjusting the composition and structure of GaN, it is possible to achieve the desired emission wavelength. 2. Structure: The structure of the LED violet lamp is also crucial for its performance. Typically, a multi-layer structure is used to improve the efficiency and stability of the lamp. The structure usually includes a p-type layer, an n-type layer, and an active layer. 3. Manufacturing process: The manufacturing process of LED violet lamps includes epitaxial growth, chip fabrication, and packaging. The epitaxial growth process is used to grow high-quality GaN films on a substrate. The chip fabrication process includes doping, etching, and slicing. The packaging process involves encapsulating the chip with materials such as epoxy or glass.
