Background

Along with the improvement of living standard, people also have higher and higher requirements on sanitary conditions, and the consumer is increasingly in demand for household sterilization, wherein, the miniaturization of UVC LED chip and module makes the components and parts that disinfect have wider design space, and its small and exquisite size makes it implant in multiple domestic appliance, can implant in refrigerator, air conditioner and the washing machine, can also depend on various household utensils, lets the user carry on with oneself, for example can all depend on article such as drinking cup, lunch-box and toothbrush. The sterilization principle of the UVC LED is as follows: the purpose of effectively inhibiting the propagation of bacteria is achieved by destroying or stopping the DNA replication process of bacteria, spores and viruses through the irradiation of ultraviolet rays, and in an ultraviolet band, the ultraviolet rays are divided into three ultraviolet rays of UVA, UVB and UVC, wherein the wavelength range of the UVA is 315nm to 400nm, the wavelength range of the UVB is 280nm to 315nm, and the wavelength range of the UVC is 200nm to 280nm, wherein the UVC band can penetrate through microorganisms and human cells to damage DNA, and the ultraviolet output with 265nm as a central band can be rapidly absorbed by the bacteria, so that the ultraviolet sterilization device is an effective sterilization means, and the UVC LED sterilization is combined with a faucet to instantly start sterilization and realize the overflow sterilization.

The appearance of the UVC LED enables a plurality of sterilization dead corners in the past to be covered, and people with specific requirements on sanitary conditions are met, the convenience is realized by not only the miniaturization of the UVC LED, but also the strong sterilization efficiency of the UVC LED, and in view of the current power and photoelectric conversion efficiency, the sterilization duration of the UVC LED is basically controlled within the order of seconds, so that the operation is very convenient. The occurrence of the UVC LED eliminates the concern of the consumer about toxicity, and the advantage of no toxic risk enables the deep ultraviolet sterilization part to be directly placed inside the water purifier and the water dispenser, so that the consumer can not be scared even if the deep ultraviolet sterilization part is in each corner of the home. When the Water guarantee convention comes into effect, the UVC LED will replace the mercury lamp by the characteristics of no toxicity and no pollution.
