In summer, before people go out, they basically do a good job of sun protection, especially girls, putting sunscreen on their faces, putting on sun-blocking shirts, putting on umbrellas, and wishing to pack their own bags. In fact, this is correct. When the ultraviolet rays in the sun shine on the skin, it is easy for the skin to have erythema, blisters, and edema. It has a detrimental effect on the human body. Go out to do a good job of UV protection. Then, Is it safe to be at home? Not necessarily, sometimes, there is a certain amount of ultraviolet light in the light, long-term exposure will also harm the human body! So, what light contains ultraviolet light ? We now take a look at what the lights contain UV !
1, ultraviolet germicidal lamp
UV germicidal lamps, in fact, is a low-pressure mercury lamp, which emits UV light to sterilize and sterilize the air by using a lower mercury vapor pressure. Ultraviolet germicidal lamps must be able to kill germs. The light must be strong, and UVC rays can be combined with quartz glass that can pass ultraviolet rays to maximize the sterilizing effect. However, it must also be noted that it is best to use it when your family members are not using it, so as not to damage the cells of the human body and to avoid eye burns caused by direct vision.
2, mosquito lamp
The mosquito catcher, as the name implies, is mainly used to capture texts. Mosquito traps use the phototaxis of mosquitoes, lure mosquitoes with blue-violet light, and then use the grid to electrocute mosquitoes. In summer, the mosquitoes appear frequently, and some people use a mosquito lamp to prevent mosquitoes. However, the blue and purple lamps that trap mosquitoes are sources of ultraviolet light. The light emitted by the lamp of the mosquito lamp is UVA. If the distance is too close or it may be prolonged exposure, it may accelerate the relaxation of the skin and even cause dark spots, which may also cause the eye to produce lesions.
3, halogen lamp
Halogen halogen lamp, also known as halogen bulb, is a variant of incandescent lamp. Halogen halogen lamp has added some halogen element gases such as iodine and bromine gas into the bulb. After the bulb is bright, the filament is heated and the tungsten is sublimated. It combines with the halogen element, and after cooling, the tungsten element solidifies on the tungsten wire. Halogen lamps have a high color temperature and good effect, so they are often used as a key illumination. However, because of its high temperature, it would not be feasible for the enclosure to only cover it with ordinary glass! In order to prevent the lampshades from softening, most halogen lamps use quartz glass, but they have both advantages and disadvantages. Quartz glass is easier to pass through ultraviolet rays than ordinary glass, so it is also more likely to cause problems with ultraviolet light penetration. However, there is no need to worry too much about the general commercial halogen lamp glass, which has a UV-resistant coating, which will not cause too much effect on the skin.
4, fluorescent or provincial light bulb
The most common fluorescent tubes and energy-saving light bulbs in the home will inevitably cause UV problems, but they do not need to be over-stressed. The ordinary glass outside the fluorescent lamp tube has actually blocked most of the ultraviolet rays; as for the energy-saving light bulb, if it is really afraid of ultraviolet rays, it can be installed with lamp shade protection to avoid being directly exposed to light.
5, LED lights
Energy-saving and multi-colored LED lights are also common elements in recent home decorating, and their light color is mainly related to the amount of ultraviolet light. The amount of ultraviolet light like a yellow light is very small, and the amount of common white light is not large. It should be noted that the blue light, basically the general brightness will not cause too much problem to the human body, unless it is a very strong blue light need to be careful.
Tips:
Since the lights of the above lamps and lanterns contain certain ultraviolet rays, the principle of “preventing direct exposure for long periods of time†must be followed when using them. Also, be careful not to get too close to the light source. If you feel the skin warming and turning red, rush to cool water, and see your doctor as appropriate!
With regard to the related content of the light containing ultraviolet light , Xiao Bian introduced it here for everyone, and hopes to help everyone! In fact, for the ultraviolet rays in the lamps and lanterns, we don't need everybody. Basically, the lamps and lanterns that are qualified for daily use are strictly tested. When we use them, just pay attention to some of them! For more information, please follow this site!Fluorescent lamp with ultraviolet light lamp lamp lamp chandeliers
