1, ultraviolet germicidal lamp
The ultraviolet germicidal lamp is actually a kind of low-pressure mercury lamp, which uses low mercury vapor pressure to strengthen and emit ultraviolet rays to sterilize and purify the air. The light that ultraviolet germicidal lamp can kill germs must be strong, and UVC light can penetrate ultraviolet timely glass to maximize the germicidal effect. But it must also be noted that it is best to use it when your family is away.
So as not to destroy human cells, but also to avoid corneal burns caused by direct vision. 2. mosquito killer
Mosquito trap lamp, as its name implies, is mainly used to catch people. The mosquito trap lamp uses the phototaxis of mosquitoes to attract mosquitoes with blue-purple light, and then shocks mosquitoes with the power grid. It is hot in summer and mosquitoes are frequent. Some people will install a mosquito trap lamp to prevent mosquitoes.
However, the blue-purple lamp that traps mosquitoes is the source of ultraviolet rays. The light emitted by the lamp tube of mosquito trap lamp belongs to UVA in ultraviolet light. If the distance is too close or exposed for a long time, it may accelerate skin relaxation, even produce dark spots, and may also cause eye diseases. 3. Halogen lamps
Ordinary halogen lamp, also called halogen bulb, is a variant of incandescent lamp.
Halogen lamps add some halogen gases, such as iodine and bromine, to the bulb. When the bulb is turned on, the filament is heated, and the sublimated tungsten will combine with halogen. After cooling, tungsten will solidify on the tungsten wire. Halogen lamps have high color temperature and good effect, and are often used as accent lighting. But because of its high temperature, it is not feasible to cover the shell with ordinary glass only! In order to prevent the lampshade from softening, most halogen lamps use timely glass, but there are advantages and disadvantages. Compared with ordinary glass, timely glass is more likely to penetrate ultraviolet rays, so it is more likely to cause ultraviolet rays. However, there is no need to worry too much. Generally, halogen glass on the market has a layer of anti-ultraviolet coating outside, which will not have much impact on the skin. 4. Fluorescent lamps or energy-saving bulbs
The most common fluorescent tubes and bulbs at home will inevitably have ultraviolet problems, but there is no need to be overly nervous. The ordinary glass outside the fluorescent tube has actually blocked most ultraviolet rays; As for saving the light bulb, if you are really afraid of ultraviolet rays, you can also install a lampshade to avoid direct exposure to the light bulb.
5, LED lights
Energy-saving multi-color LED lamps are also common elements in recent home improvement, and their lighting colors are mainly related to the amount of ultraviolet rays. For example, the ultraviolet ray of yellow light is very small, and the ultraviolet ray of ordinary white light is not large either. It should be noted that the general brightness of blue light will not cause much problem to human body, unless it is extremely strong blue light, you need to be careful.
Tips:
Because the light of the above lamps contains certain ultraviolet rays, the principle of "avoiding long-term direct irradiation" should be followed when using. In addition, be careful not to be too close to the light source. If you feel hot and red, rinse with cold water and call a doctor as appropriate!
