Short wave UVC LED, with wavelengths of 200~275 nanometers, also known as short wave sterilizing ultraviolet rays. It has the weakest penetration and can't penetrate most of the transparent glass and plastic. The short - wave ultraviolet rays contained in the sun are absorbed almost completely by the ozone layer and are absorbed by the ozone layer before reaching the ground.

The degree of damage to human body: UVC LED in nature is absorbed by the ozone layer because it has not reached the ground, and its influence on the skin can be ignored. In fact, the damage of short wave ultraviolet to human body is very large, and it can not directly irradiate the human body. If direct exposure, short time exposure can burn the skin, long-term or high intensity radiation can cause skin cancer.

Field of application: the ultraviolet bactericidal lamp is the UVC LED short wave ultraviolet ray. Short wave ultraviolet light is widely used in hospitals, air conditioning system, disinfection cabinet, water dispenser, water treatment equipment, sewage treatment plant, swimming pool, food and beverage processing and packaging equipment, food factory, cosmetics factory, dairy factory, brewery, beverage factory, bakery and freezer etc..

The advantages and disadvantages of ultraviolet radiation

Advantages of ultraviolet: 1) disinfection and sterilization; 2) promoting bone development; 3) being beneficial to blood; 4) occasionally treating certain skin diseases; 5) promoting mineral metabolism and vitamin D formation in vivo.

The disadvantages of UV: 1) wrinkle skin aging; 2) produce spots; 3) cause dermatitis; 4) cause skin cancer.
