we provide customers with application support, design and documentation on using UVC LEDs in disinfection applications.

With the increasing improvement of people's living standards, the awareness of healthy water is also increasing. Since water is an indispensable resource for life, it is necessary to have good sterilization and purification methods to ensure drinking healthy drinking water. From the past to the present, people have also used many methods, mainly divided into physical methods and chemical methods. For example, physical methods include high-temperature boiling, burning, high-pressure steam and other methods, and chemical methods include chlorine, ozone and other methods.

At present, there are two major technical products in UV sterilization technology to form an obvious contrast: low pressure UV sterilization mercury lamp products and deep UV LED products.

Recently, we often mention the ultraviolet sterilization bands of 254nm, 275nm, 222nm and 405nm. In order to let friends know these bands better, let's talk about this topic today.

LED is a very sensitive electronic component, so we must be very careful during storage and use, otherwise it will cause led moisture, device breakdown or failure, and many problems in the use of LED.

Deep ultraviolet light emitting diode Deep ultraviolet light emitting diode (duv-led) has many advantages such as environmental protection, mercury free, long service life, low power consumption, fast response, light structure and so on. In recent years, deep ultraviolet LED technology has made rapid development, mainly reflected in the continuous improvement of light efficiency and reliability. On the one hand, it is due to the progress of nitride material epitaxy and doping technology in the process of chip manufacturing, on the other hand, it is due to It is applicable to the development of deep UV LED packaging technology.
