Ultraviolet (UV) LEDs emit light with wavelengths ranging from 250 to 280 nm. This wavelength, known as ultraviolet C (UV-C) light, kills or inactivates microorganisms by damaging their DNA. UV-C light emitted by UV disinfection lamps is considered germicidal UV light. Germicidal lamps UVC LED sterilizers for tools and workspaces used in medical facilities and biological laboratories. Ultraviolet Germicidal Irradiation (UVGI) technology uses ultraviolet light to inactivate and break down infectious organisms such as bacteria and viruses. This technology is ideal for maintaining peak sterilization in the medical field.

UVC LED Sterilization:

UVC LED is the deep ultraviolet C-band LED lamp, which is a band with the shortest wavelength and the highest energy, and has a practical effect on sterilization and disinfection. Scientific research has shown that deep ultraviolet UVC in the 260-280nm band can quickly destroy the DNA or RNA molecular structure of microorganisms, promote bacterial death or fail to reproduce, so as to achieve the purpose of sterilization. Among all ultraviolet rays, UVC in this band has the strongest bactericidal effect. For example, GK's latest canpuri upper air sterilization LED disinfection equipment adopts 275nm band, which can be used in supermarkets, offices, hospitals, kitchens, living rooms, and other public places, and meets the US FDA certification standards.

UVC LED technology intelligent sterilization, belongs to pure physical sterilization, 0 ozone, 0 mercury, the whole sterilization process does not need to add any chemicals, truly achieve complete environmental protection.

As the performance of UVC LEDs (deep ultraviolet LEDs) improves, the use of this relatively new technology in disinfection, life sciences, and environmental monitoring instruments is growing rapidly. UVC LEDs can reduce footprint and power consumption, thereby increasing the cost of ownership for the end user.

There are countless bacteria and harmful microorganisms hidden in the air. Against highly infectious viruses, air purification is our first line of defense. UVC LED UV sterilization can be installed on most devices that require fresh, fresh air, such as air purifiers, refrigerators, etc. Under the influence of the epidemic, people pay special attention to the cleaning and disinfection of frequently contacted objects in life. Objects that directly contact the skin, such as masks and clothing, need to undergo a series of disinfection and sterilization treatments. UVC LED UV disinfection equipment can effectively remove organic residues from various surfaces. At present, the new coronavirus continues to spread around the world, sterilization and disinfection have gradually become a daily requirement, and the concept of health has been deeply rooted in the hearts of the people.

Deep UV LEDs have been gradually recognized by the market with many advantages such as safety, environmental protection, compactness, high efficiency and low consumption. They have been initially used in water treatment, air sterilization, food preservation and other fields.

Deep UV LED Market

Deep UV LED has been recognized by the market for its performance advantages such as safety, environmental protection, compactness, high efficiency and low consumption, and has been seen in the fields of water purifiers, maternal and child products, air conditioners, refrigerators and other high-end consumer goods. The principle of deep ultraviolet sterilization and disinfection is that deep ultraviolet rays can destroy the DNA or RNA molecular structure of genetic material in microorganisms, resulting in the inability of bacteria to reproduce or even inactivation, so as to achieve the purpose of sterilization and disinfection. According to BIS Research Analysis data, by 2023, the market size of UVC will be It will be close to US$500 million in 2023, with an average annual growth rate of 41.9%. The main parameter to measure the sterilization efficiency is the irradiation dose received by the bacteria (irradiation dose (mJ/cm2) = irradiation time (s) * deep ultraviolet irradiation intensity (mW/cm2)), the greater the irradiation dose, the higher the disinfection efficiency. .

Deep UV LED Sterilization Advantages

Compared with other sterilization methods such as chlorination, ozone and UV mercury lamp sterilization, deep ultraviolet LED sterilization has many advantages:

High-efficiency sterilization, the UVC segment ultraviolet light emitted by deep ultraviolet LEDs generally kills bacteria and viruses within a few seconds. Traditional water sterilization methods such as chloride and ozone generally take 20 minutes to 1 to achieve deep ultraviolet sterilization efficiency. Hour;

Extensive sterilization. Since microorganisms such as bacteria and virus antigens are not resistant to ultraviolet light, deep ultraviolet light can efficiently kill almost all bacteria and viruses, and deep ultraviolet LED sterilization technology can also be used to a certain extent. Inhibit the growth of some higher aquatic organisms, such as algae, red worms, paramecia, etc.;

Safe and environmentally friendly (without mercury), the most obvious advantage of deep UV LED devices compared to mercury-excited UV lamps on the market is that their sterilization light source does not contain mercury, and mercury is a heavy metal substance, commonly known as mercury, and mercury can be used at room temperature. Evaporation, mercury vapor and mercury compounds are highly toxic (chronic). In the sterilization process of traditional ultraviolet mercury lamps, once the lamp tube is broken, it will cause serious water pollution, and deep ultraviolet LED devices are a safe and reliable device. No heavy metals, simple operation, safe and reliable operation;

Energy saving, long life and low maintenance cost, deep ultraviolet LED sterilizer is gradually replacing the mercury lamp ultraviolet sterilizer commonly used in the market. One of the important reasons is that the power consumption of ultraviolet LED is low, which is very energy-saving. The power of deep ultraviolet LED is about the same as that of mercury lamp. 1 in 10, which is a significant cost savings;

Small size, flexible design, easy installation, deep ultraviolet LED devices, small size, flexible design of the sterilization device, can be used in small spaces where traditional mercury mercury lamps cannot be used.

Deep UV LED Applications

Deep ultraviolet LED products are gradually recognized in the market due to their many advantages, and have been initially used in water treatment, air sterilization, food preservation and other fields.
