COVID-19's wreak havoc has given UVC LED opportunities for development. In many public places, we can often see the UVC LED bactericidal products. Even in the daily life of families and individuals, the popularity of such products is becoming higher and higher.
At present, the types of UVC led sterilization products on the market are blooming everywhere. For consumers, they have more choices in terms of price and function. Different products are selected for different application scenarios. So how to choose more suitable and practical UVC led sterilization products? Let's share some dry goods.
1. Is there a test report
UVC LED market is mixed, and products with test report shall be given priority in selection.
2. Identify wavelength
At present, the wavelength that can really play a better bactericidal effect is UVC led260-285nm. Consumers should note that because the UVC led band is "invisible light", it is difficult for users to feel its working state. Some non mainstream manufacturers may make up the number with 320-405nm. For example, all UVA LEDs are called UVC LEDs, or 30% UVC LEDs are doped with 70% UVA LEDs. In this case, the manufacturer will not tell the truth, which is difficult to distinguish. Consumers can identify from two aspects:
1) If it is found that the price is too cheap year-on-year, it should be carefully considered;
2) Select products with test reports;
3) Identify brand chip light source manufacturers;
3. Consider radiated power
Theoretically, under the same light power of a single lamp bead, the more the number, the greater the power, the higher the sterilization efficiency and the larger the sterilization range. The number of lamp beads used in products under different application scenarios is naturally different. If 9 lamp beads are used in the disinfection package, it can achieve pure physical and powerful sterilization for 3 minutes. The deep ultraviolet LED disinfection vehicle is 96 lamp beads, which can complete the air disinfection and replacement of more than 20 ㎡ within 1 hour. Of course, the more light beads of similar products, the better sterilization effect and higher price.
4. Distinguish the type of light source
At present, the mainstream light sources are divided into ultraviolet mercury lamp and ultraviolet LED. The difference between the two is that 185nm mercury lamp contains ozone and mercury, and 254nm mercury lamp does not contain ozone but mercury, which is harmful to human body and the environment. Ultraviolet LED is an energy-saving and environment-friendly light source, but the electro-optic conversion efficiency of ultraviolet LED is only 10% of that of ultraviolet mercury lamp. At present, the use of UV mercury lamps has not been forcibly prohibited, but according to the trend of mercury prohibition in the global Minamata convention, it is inevitable to eliminate UV LED lamps in the future when their performance and price can be comparable to that of UV mercury lamps.
5. Whether there is protection design
UVC LED can not only kill bacteria, but also cause certain damage to organisms. For example, direct exposure for a short time will burn eyes, and long-term and high-intensity irradiation will damage skin. Therefore, when selecting products, try to select products with protective functions, such as sterilization bag can not work when opening the flip, hand-held sterilization stick can not work when the lamp bead is upward, and the deep UV LED disinfection vehicle is equipped with radar sensing module. When people come, the light is off and when people walk, the light is on; The air killing lamp uses the fan for convection to kill the bacteria in the space inside the killing lamp, so as to avoid direct illumination killing. The elevator cannot work when organisms are detected by infrared and other auxiliary technologies, and the ultraviolet light of the air purifier is limited to the interior of the product.
6. Consider your own killing needs
If you only need to disinfect small objects in life, such as pet products, mother and baby products, underwear, masks, cosmetics, office supplies, glasses, mobile phones, you can choose to buy disinfection bags, which are small and portable and can easily realize aseptic storage; If it is for desktop, door handle, etc., hand-held sterilization stick can be considered for more flexible use; If there is a need to kill the kitchen and bathroom, you can buy targeted tools, such as UVC led knife holder, chopsticks disinfection bucket, etc; If it is necessary to kill synchronously during cleaning, UVC led sweeping robot can be considered; The home room is sterilized. The UVC led fresh air conditioner can continuously circulate the indoor air to the UVC ultraviolet sterilization place for sterilization, so as to ensure the health and cleanliness of the air in the indoor space; Disinfection vehicles are a good choice for killing in public places. The killing range is wider and can be moved to realize no dead corner sterilization
Qingdao fluorescent Innovation Technology Co., Ltd. has a professional postdoctoral team, focusing on the research of ultraviolet sterilization application. After years of deep cultivation in the ultraviolet industry, the company has obtained a number of national invention and utility model patents. At present, a number of sterilization module products have been put into the market.
