Deep ultraviolet light emitting diode Deep ultraviolet light emitting diode (duv-led) has many advantages such as environmental protection, mercury free, long service life, low power consumption, fast response, light structure and so on. In recent years, deep ultraviolet LED technology has made rapid development, mainly reflected in the continuous improvement of light efficiency and reliability. On the one hand, it is due to the progress of nitride material epitaxy and doping technology in the process of chip manufacturing, on the other hand, it is due to It is applicable to the development of deep UV LED packaging technology.

With the advantages of small volume, fast opening speed and low power consumption, deep UV LED has opened up a new application scenario in the deep UV sterilization market, and formed a trend substitution for UV mercury lamp, from air-conditioning and air purification for air sterilization; In the scenes of water sterilization, such as water tank bacteriostasis, direct drinking water, humidifier to surface sterilization, intelligent toilet and toothbrush disinfection, deep UV uvc-led began to show great application value and potential. Today, let's talk about UVC led.

Ozone sterilization principle: UVD ultraviolet light with a wavelength of 185nm irradiates the air, which can decompose oxygen molecules in the air, generate O atoms, and then combine with oxygen to produce ozone. Ozone has strong oxidation, can destroy and decompose the cell wall, penetrate into the cell, oxidize and decompose and destroy glucose oxidase, RNA / DNA, protein, lipid and polysaccharide macromolecular polymers, so as to destroy the metabolism and reproduction process of bacteria and die, so as to achieve the effect of sterilization and disinfection.

Under the catalysis of the epidemic, with the surge of consumer demand for sterilization and disinfection, the UV LED industry is developing rapidly. Mankind needs effective disinfection and sterilization means to safeguard life safety!

Pure water and tap water show good transmission characteristics to light with wavelength between 250 ~ 800 nm. The transmittance of 5mm thickness is more than 80%. When the wavelength is shorter than 250 nm, the optical absorptivity increases rapidly. Especially tap water has stronger light absorption of < 250 nm. 2.4cm attenuation to 70%; 8.5cm attenuation to 30%; 16.3cm attenuation to 10%.

The light of deep UV LED lamp beads is often used in disinfection and deodorization because of its good sterilization effect. It is widely used in the industry. What problems should be paid attention to in the use of deep UV LED lamp beads?
