(1) in the application of surface sterilization, UV surface sterilization device is widely used in food, electronics, semiconductor, liquid crystal display, plasma TV, crystal vibration child, precision devices, chemical, medicine, health care, biology, beverage, agriculture and other fields. UV light source irradiation of food, materials and other surfaces, with fast, efficient, pollution-free sterilization effect, so as to maintain the high quality of products. Compared with the traditional sterilization method, surface sterilization has the characteristics of fast sterilization speed, continuous processing and batch processing, simple operation, environmental protection and no secondary pollution.

(2) Application in water treatment. The use of ultraviolet sterilization lamp for water treatment there are two methods of immersion and flow, directly put the ultraviolet lamp into the water, known as immersion; The ultraviolet lamp is used in the casing and is called the over-current. At present, the main method is through flow. The operating principle of the overflow equipment is that the flow of water at a certain velocity of pressure generated by the pump flows through the quartz sleeve which can penetrate ultraviolet light, and the ultraviolet light is generated to disinfect and sterilize the water. Its characteristic is that the flow rate of water is very fast, generally in the quartz jacket flow through the ask is not more than 1s, so the ultraviolet intensity of the sterilization lamp is very high.

(3) Application in medical and environmental hygiene. The use of ultraviolet disinfection lamps for air sterilization in hospitals has been decades of history, there are static air direct illumination method and flow air disinfection method. Static air direct illumination method uses ultraviolet disinfection lamp direct irradiation, its disadvantage is that the irradiation can not be disinfected, disinfected people can not be present. Mobile air disinfection method using dynamic air disinfection machine, this disinfection machine just can make up for the above two defects. The working principle of the mobile air disinfection machine is to sterilize the air in the disinfection machine through indoor air circulation, so as to achieve the purpose of disinfection of the whole indoor air. The structure of this kind of disinfection machine mostly uses the housing of the indoor unit of the household air conditioner. Mobile air disinfection machine, has now developed into a variety of disinfection equipment, including sterilization air conditioning, air purifier. The use of products that used to be used only in hospitals now finds their way into homes, offices and bulletin boards. Functions are also diversified. Products used only for sterilization can now be used for health care and prevention, and become health-related products [1].

(4) Sanitation and aseptic disinfection are the necessary requirements for the production, processing, filling and packaging of food. Using ultraviolet lamps for disinfection is a cost-effective and environmentally friendly alternative to the frequent use of chemical processes.

1. Surface disinfection of packaging materials: In a filling plant, bacteria on the surface are killed by exposing them to short-wave UV-C radiation. The degree of packaging material purity is used to determine whether the packaging material is unqualified packaging.

For example, UV disinfection is used in the filling machines of commodities and beverages, in the refrigeration of LIDS, cups, covered and foil-wrapped beverages, and in dairy products and other foods. Heraeus UV lamps can extend the shelf life of food products because they use UV disinfection technology.

2. On the conveyor belt: for the transport of meat, fish, potato products, fruits and vegetables. To further improve the economic effect, it is necessary to further strengthen the hygienic process in the food processing process.

3. Food surface disinfection: such as fruit and vegetable products and hard cheese surface disinfection.
