Brief analysis of UVC LED application

Deep-ultraviolet LEDs have gradually been 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.

1. Deep UV LED Market

Deep UV LEDs have been recognized by the market for their performance advantages such as safety, environmental protection, compactness, high efficiency, and low consumption. They have already seen clues in the fields of water purifiers, maternal and child products, air conditioners, refrigerators and other high-end consumer products. The principle of deep ultraviolet sterilization and disinfection is that deep ultraviolet rays can destroy the genetic material DNA or RNA molecular structure in microorganisms, causing bacteria to be unable to reproduce or even inactivate, thereby achieving the purpose of sterilization and disinfection. According to BIS Research Analysis data, by 2023, the market scale of UVC will be It will be close to 500 million US dollars in 2023, with an average annual growth rate of 41.9%. The main parameter to measure the sterilization efficiency is the radiation dose received by the bacteria (radiation dose (mJ/cm2) = radiation time (s) * deep ultraviolet radiation intensity (mW/cm2)). The greater the radiation dose, the higher the sterilization efficiency . UV radiometer is used to test the uv irradiation intensity.

Second, the advantages of deep ultraviolet LED sterilization

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

Efficient sterilization, the UVC segment ultraviolet light emitted by the deep ultraviolet LED generally kills bacteria and viruses within a few seconds. The traditional water sterilization methods such as chloride and ozone generally take 20 minutes to 1 hour;

Wide range of bactericidal properties, because bacteria, virus antigens and other microorganisms are not resistant to ultraviolet light, deep ultraviolet light can kill almost all bacteria and viruses with high efficiency, 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, bloodworms, paramecium, etc.;

Safe and environmentally friendly (without mercury), the most obvious advantage of deep-ultraviolet LED devices over the mercury-excited UV lamps currently on the market is that the germicidal light source does not contain mercury. Mercury is a heavy metal substance, commonly known as mercury, which can be used at room temperature. Evaporation, mercury vapor and mercury compounds are highly toxic (chronic). In the sterilization process of traditional ultraviolet mercury lamp germicidal lamps, once the lamp tube breaks, it will cause serious water pollution. Deep ultraviolet LED devices are a safe and reliable device. Does not contain heavy metals, simple operation, safe and reliable operation;

Energy saving, long life, low maintenance costs, deep ultraviolet LED sterilizers are gradually replacing the common mercury lamp ultraviolet sterilizers on the market. One of the important reasons is that ultraviolet LEDs have low power consumption and are very energy-saving. The power of deep ultraviolet LEDs is about mercury lamps. One tenth, this ratio greatly saves costs;

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