1608 UV LEDs, also known as 1608 ultraviolet light-emitting diodes, have become increasingly popular in various industries due to their compact size, high efficiency, and wide range of applications. This article aims to provide an in-depth introduction to the 1608 UV LED industry, covering its history, technology, applications, market trends, and future prospects.

History of 1608 UV LEDs

The development of UV LEDs dates back to the 1960s when the first UV LED was invented. However, it was not until the late 1990s that the technology gained significant attention, thanks to the advancement of semiconductor materials and manufacturing processes. The 1608 UV LED, with its small size and high performance, was introduced to the market in the early 2000s and has since become a staple in many applications.

Technology of 1608 UV LEDs

1608 UV LEDs are based on semiconductor materials that emit UV light when an electric current is applied. The most commonly used materials for UV LED chips are aluminum gallium indium phosphide (AlGaInP) and aluminum gallium indium arsenide (AlGaInAs). These materials can emit UV light in the range of 365 to 400 nm, which is suitable for various applications such as curing, disinfection, and fluorescence. The structure of a 1608 UV LED typically consists of a p-n junction, a sapphire substrate, and a metal reflector. The p-n junction is formed by diffusing the p-type and n-type materials into the sapphire substrate. The metal reflector is used to enhance the light extraction efficiency of the LED. The small size of the 1608 UV LED is achieved by using a micro-structured sapphire substrate, which allows for better light extraction and reduces the thermal resistance.
