What is a UV Lamp
Ultraviolet lamp is a kind of lamp product that can emit ultraviolet rays. It is also an essential tool for observing samples in the field of biochemistry. It is also used for indoor disinfection and the most important physical method to reduce the generation of bacteria. Ultraviolet lamps can emit wavelengths within 10-400nm, and are also used in the production of various functional lamps, such as strong ultraviolet high-pressure mercury lamps, capillary ultra-high pressure mercury lamps, ultraviolet iron lamps, excimer discharge lamps, etc.
UV Lamp Features
1. The light radiated by ultraviolet rays will change the genetic structure of microorganisms and damage the DNA, so that the microorganisms lose their reproductive and repair functions, and finally achieve the inhibitory effect of bacteria. In addition, the use of ultraviolet light for sterilization work, without worrying about the generation of odor, and no harmful chemical components will remain. Due to its colorless properties, it has been gradually used in many modern water treatment and has been put into treatment in many countries.
2. Ultraviolet lamps actually use mercury lamps to emit ultraviolet rays, and the released amount is relatively large. If certain protective measures are not taken, it is easy to cause great damage to the human body. If the skin is exposed to ultraviolet light, the degree of itching, redness, peeling and other problems will occur to a certain extent. If the degree is serious, it will cause skin diseases. In addition, such lamps also have a great impact on the human eye. Staying in the radiation space for a long time is easy to cause inflammation of the corner of the eye, and even suffer from cataracts.
3. Ultraviolet lamps are also widely used in automotive applications, and these lamps have a variety of styles, which not only play a good role in disinfection and sterilization, but also have a certain decorative effect. After the car is treated with ultraviolet light, the air inside is fresh, the odor is completely removed, and it will not cause harm to the human body.
4. Ultraviolet lamps have a significant effect on indoor disinfection, will not affect the environment, and reduce the generation of pollution. However, when using it, care should be taken to avoid direct contact with the skin and eyes of the lamp to reduce the impact of radiation.
The last thing I need to mention is that the anti-mosquito UV lamps used in restaurants and milk tea shops are different from the UV lamps introduced above. Therefore, consumers do not need to worry about radiation problems and can use them with confidence." "Everyday exposure to ultraviolet light, from turning it on to leaving the disinfection room, will be in contact for a few seconds every day. Will it be harmful to the human body in the long run?
If the time is very short, the harm is not great. Be careful not to expose your eyes and bare skin to the radiation range of UV-C. Pay special attention not to look directly at the lamp tube, and it is best to wear glasses (or goggles) in the disinfection room.
Our UV manufacturers, employees and technicians have to assemble and test UV lamps every day, and use cardboard to block the light of the UV lamps. For 20 years, my skin and eyes are fine." "UV disinfection lamp for day or night use
Ultraviolet disinfection lamps can be used during the day and at night, but be careful to avoid light when using them. Because some bacteria in the air rely on the ""photoreactivation enzyme"" in the body to obtain energy, that is, repair damaged DNA through light, if the ultraviolet disinfection lamp is not protected from light, the damaged cells will restore normal vitality under visible light, called photoresurrection. Therefore, try to choose to use ultraviolet disinfection lamps at night. If it is during the day, you can draw the curtains to keep the light dim.
How to use UV disinfection lamp:
1. Air disinfection: When using, the doors and windows should be closed, and the room should be kept dry, and then the disinfection lamp should be turned on. The disinfection distance should not exceed 2 meters, and the disinfection time should be 30-40 minutes each time. If the light needs to be turned on again after turning off, it should be turned on again after 3-4 minutes. When the ultraviolet disinfection lamp is irradiated, it is strictly forbidden for personnel to enter the room, and the window should be opened for ventilation after the disinfection lamp is used.
2. Disinfection of the surface of items: spread out or hang the items to make them fully exposed to direct irradiation. When in use, the irradiation time of ultraviolet rays should not be less than 30 minutes, and the high-intensity, low-ozone ultraviolet germicidal lamps The irradiation time is preferably 30 to 60 minutes.
Precautions for UV disinfection lamps:
1. Ultraviolet rays have certain damage to human skin and mucous membranes. When using ultraviolet germicidal lamps, you should pay attention to protection. You must never look directly at the ultraviolet light source, otherwise your eyes will be hurt.
2. Ensure that the disinfection method is correct. When used for air disinfection, the disinfection distance should not exceed 2 meters, and each disinfection time is 30-40 minutes. When used for disinfection of articles, the irradiation time shall not be less than 30 minutes.
3. The surface of the ultraviolet germicidal lamp tube should be kept clean and free of dust, wiped with a 95% ethanol cotton ball once a week, and it is best to keep a record.
4. When disinfecting articles with ultraviolet rays, the irradiated surface should be directly irradiated with ultraviolet rays, and a sufficient irradiation dose should be achieved. When irradiating the air, all cabinet doors and drawers should be opened to ensure that all spaces are irradiated with ultraviolet rays, and disinfection should be as free as possible.
5. Because the service life of the ordinary ultraviolet germicidal lamp is 1000-3000 hours, it is necessary to make a record every time the ultraviolet germicidal lamp is used. In addition, the ultraviolet intensity of the ultraviolet germicidal lamp should be checked regularly with the ultraviolet intensity command card.
However, the UV lamps produced by Ningbo Youwei Optoelectronics have a lifespan of 8,000-10,000 hours, so there is no need to worry about their lifespan, and they can basically be used for more than 10 years at home. The light decay rate is also very low, almost negligible.
Choosing a high-quality UV lamp is equal to a lot less trouble. One choice, accompany for 10 years
