UV purple LED lamp, also known as ultraviolet purple LED lamp, has become an essential lighting solution in various industries due to its unique characteristics and applications. This article aims to provide an in-depth introduction to the UV purple LED lamp industry, covering its definition, technology, applications, market trends, and future prospects.

Definition and Characteristics

UV purple LED lamp refers to an LED lamp that emits purple light with a peak wavelength of around 405nm. It belongs to the category of ultraviolet light, which is invisible to the human eye. The purple light emitted by the lamp has a shorter wavelength than blue light, which allows it to penetrate deeper into the surface of objects. This characteristic makes it widely used in various fields such as curing, disinfection, and detection.

Technology and Production

The production of UV purple LED lamps involves several key technologies. Firstly, the selection of raw materials is crucial. High-quality gallium nitride (GaN) substrates are required to ensure the lamp's stability and lifespan. Secondly, the epitaxial growth process is essential for forming the LED chips with purple light-emitting layers. The structure and composition of the LED chips directly affect the lamp's performance. Lastly, the packaging and heat dissipation technology are also critical to ensure the lamp's long-term stability and reliability.

Currently, the mainstream production methods of UV purple LED lamps include chip-on-board (COB) technology and surface mount technology (SMT). COB technology can achieve higher light output and better heat dissipation performance, while SMT technology is more suitable for mass production and cost control.
