Semiconductor UVC LED UV sterilization technology
Technical working principle
Understand the core working mechanism of semiconductor UVC LED light source sterilization technology, from light source excitation to microbial inactivation throughout the entire process
Light source excitation
When current passes through the semiconductor chip of solid-state UVC LED, the electrons and holes in the chip recombine, releasing energy and exciting the generation of ultraviolet light in the UVC band
ultraviolet radiation
The generated UVC ultraviolet radiation radiates into the surrounding space or water flow, with its wavelength precisely focused on the range with the strongest killing effect on microorganisms. It can penetrate the cell membrane of microorganisms and directly reach their internal genetic material
Destruction of genetic material
After being absorbed by microorganisms, UVC ultraviolet rays can damage the molecular structure of their DNA and RNA, preventing microorganisms from reproducing and achieving bactericidal effects
Sterilization completed
Under the continuous action of UVC LED light source, bacteria, viruses, fungi and other microorganisms in water, air or object surfaces quickly lose their activity, achieving the purpose of sterilization and disinfection
Working principle diagram
The semiconductor UVC LED light source sterilization technology uses precisely controlled semiconductor luminescence to generate specific wavelengths of ultraviolet light, efficiently killing various microorganisms. The entire process does not require chemical reagents, there is no secondary pollution, and it is a green and environmentally friendly disinfection and sterilization method
Advantages of semiconductor UVC LED light source sterilization technology
Compared to traditional ultraviolet sterilization technology, semiconductor UVC LED light source sterilization technology has outstanding advantages in multiple aspects
Efficient and fast
UVC LED light source can instantly reach the rated sterilization power without preheating, and can achieve efficient sterilization in a short period of time, which has significant advantages for scenes that require rapid processing
Safe and reliable
It does not contain harmful substances such as mercury, avoiding environmental pollution and safety hazards caused by the breakage of traditional mercury lamps. At the same time, its emitted ultraviolet light has a concentrated wavelength and is less likely to produce secondary pollutants such as ozone
Energy saving and durable
The energy consumption is only a part of traditional mercury lamps, which can effectively reduce energy consumption. Moreover, its service life can reach tens of thousands of hours, far longer than traditional mercury lamps, reducing replacement frequency and maintenance costs
Compact and flexible
The solid-state structure makes it compact in size, lightweight, and easy to integrate into various devices such as small water purifiers, portable sterilizers, air conditioning vents, etc., making it more suitable for a wider range of scenarios
Strong controllability
The output power and working time can be precisely controlled through circuit design, and adjusted according to different sterilization requirements to achieve precise sterilization and avoid energy waste
