Harm of uv lamp to human body. Many times, what we use is harmful to our body in some ways, so we should pay special attention to protection when using it. Let me take you to understand the harm of uv lamp to human body, hoping to help you.

Harm of ultraviolet lamp to human body 1 1. Harm to human genes:

Long-term exposure to ultraviolet light can cause gene mutation and skin cancer. Just like summer, it is also true that you can't bask in the sun for a long time in the cool sun. Because there are ultraviolet rays in the sun, quilts are usually disinfected in the sun. However, if the ultraviolet lamp is exposed to the sun for a long time, it will do some harm to the body. Ultraviolet lamp will cause some harm to human body more or less, so take protective measures when using it.

Second, the harm to human skin:

Ultraviolet lamp uses the ultraviolet light released by mercury lamp to complete the sterilization function, and it emits a lot of ultraviolet energy. If there is no protection method, it is easy to cause infinite harm to the human body. Under the irradiation of ultraviolet rays, it is very easy to cause great damage to the skin. If the exposed skin is exposed to this ultraviolet radiation, it will appear redness, swelling, itching, desquamation and other phenomena, which may lead to cancer and skin tumors and endanger life. Not only that, it will also hurt the eyes, and long-term radiation may lead to cataracts. However, its disinfection and sterilization effect is conducive to the establishment of a sterile environment in hospitals, but protective measures should be taken when using it.

Third, the harm to the central nervous system:

Ultraviolet rays act on the central nervous system, which may lead to headache, dizziness and elevated body temperature. When it acts on the eyes, it can cause conjunctivitis and keratitis, called actinic ophthalmia, and it may also induce cataracts. The ultraviolet rays generated in the welding process will make the welder suffer from electro-optic ophthalmia (curable). It is the "invisible killer" of both eyes, which will cause inflammation of conjunctiva and cornea, and long-term illumination may cause cataracts. As for the small UV lamps used by some restaurants and families to kill mosquitoes, the lighting principle is different, so consumers don't have to worry. Experts suggest that when using UV lamps, there should be no people indoors, and the disinfection time should be 30 minutes to 1 hour. Prevent looking directly at the light source; Family members must wear protective glasses or sunglasses when operating disinfection lights.

Harm of ultraviolet lamp to human body 2 What are the hazards of ultraviolet disinfection lamp to human body?

Core Tip: Ultraviolet lamp can use ultraviolet rays to achieve sterilization and disinfection. It emits a lot of ultraviolet energy, which will do great harm to human body if there are no protective measures. Therefore, in daily life, when using ultraviolet disinfection lamps, try not to have anyone indoors. After use, do a good job of window opening and ventilation in time, and do not enter until it is ventilated for more than one hour.

Ultraviolet disinfection lamp is used to kill bacterial propagules, fungi, coronavirus and so on. All surfaces, water and air polluted by these viruses can be disinfected by ultraviolet rays. Ultraviolet disinfection lamps are mainly divided into high voltage, medium voltage and low voltage, and generally low voltage is used. Ultraviolet sterilization technology has been widely used in more and more fields, especially in air sterilization and surface sterilization. So, what harm does ultraviolet disinfection lamp do to human body?

First of all, ultraviolet disinfection lamps do great harm to the skin. The skin exposed to the disinfection lamp will have symptoms such as redness, pain and desquamation, and diffuse erythema, itching or burning sensation, and tender and smooth skin will form blisters or edema. If you are exposed to ultraviolet disinfection lamp for a long time, it may cause general discomfort, and skin cancer and skin tumor may occur seriously.

Secondly, the damage to the eyes is also very great. Ultraviolet disinfection lamp can cause conjunctivitis and keratitis, and the eyes will be red, swollen, painful and tearful. Long-term exposure will cause corneal deformation, resulting in impaired vision, easy to induce cataracts and even blindness.

The odor released by the ultraviolet disinfection lamp will also strongly stimulate people's respiratory tract, causing sore throat, chest tightness, cough, bronchitis and emphysema. If pregnant women smell it, it will also cause pregnant women to have deformed children. In addition, long-term ultraviolet radiation may lead to gene mutation with carcinogenic tendency.

In a word, it is recommended not to stay in the environment of ultraviolet radiation for a long time when using ultraviolet lamp for disinfection. Proper irradiation with ultraviolet disinfection lamp will be beneficial to human body, but excessive irradiation will do great harm to human health. In daily life, when using ultraviolet disinfection lamp, people are forbidden to enter the room. When you need to enter, you should first turn off the ultraviolet disinfection lamp and open the window for ventilation in time to avoid inhaling too much ultraviolet rays.

Harm of uv lamp to human body Does LED lamp have ultraviolet ray?

Ultraviolet led generally refers to an LED with a luminous center wavelength below 400nm, but sometimes it is called near ultraviolet LED when the luminous wavelength is greater than 380nm, and it is called deep ultraviolet LED when it is less than 300nm. Due to the high sterilization effect of short-wavelength light, ultraviolet LED is often used to sterilize and deodorize refrigerators and household appliances. In terms of products, Niya Chemical Industry listed the varieties with emission center wavelength of 365nm-385nm, and NitrideSemiconductor listed the varieties with emission center wavelength of 355nm-375nm. The development of deep ultraviolet LED with wavelength less than 300nm is also very active.

Uv LED application

Ultraviolet rays are mainly used in biomedicine, anti-counterfeiting identification and purification (water, air, etc.). ), computer data storage and military. Moreover, with the development of technology, new applications will appear constantly, replacing the original technology and products, and ultraviolet LED has broad market application prospects. For example, the ultraviolet LED phototherapy instrument is a very popular medical device in the future.

But at present, the technology is still in the growth stage. Semiconductor deep ultraviolet light source has great application value in lighting, sterilization, medical treatment, printing, biochemical detection, high-density information storage and secure communication.

Does the led light have ultraviolet rays? Yes, that's true. At this time, led lights are very important. They are usually used on the operating table to play a role in sterilization and disinfection, giving people a sterile operating environment and reducing the concentration of bacteria in the air, thus better reducing infection for patients. The lamp not only has the function of illumination, but also has the function of sterilization.
