Home decoration, will buy a variety of lamps and lanterns, because every room needs lights. There are many friends in the selection of lights, just look good, bright or not, but ignore the other. In fact, there are healthy and unhealthy lamps and lanterns. For example, strobe lamps, UV radiation, electromagnetic radiation, heat radiation and dazzling light and other kinds of light pollution, is affecting the health of the body, called unhealthy lamps.
So what is a healthy light fixture? How can we get healthy lamps? Some of this is to give you the answer in this article. The so-called healthy lamps and lanterns, is no harm to the human body lamps and lanterns. The industry's judgment of it, generally from the four elements to measure: high apparent finger (Ra> 90), no video flash, anti-glare (UGR < 19), no blue light hazard. Specific general can pass the following five aspects, basically you can buy healthy lamps and lanterns.
(A) no video flash can appear
We are judging whether the first point of health of the lamps and lanterns, is to focus on whether the lamps and lanterns we have chosen stroboscopic source of light. The light source of our household lamps and lanterns, luminous flux generally changes periodically with the AC voltage, there may be light and dark intensity and other stroboscopic phenomenon. And this strobe phenomenon, indeed, and may be harmful to human health and the human visual system.
In the purchase of lamps and lanterns, the first point should pay attention to the stroboscopic phenomenon that can not be visible. Otherwise, it is unhealthy lamps and lanterns.
①, such as common incandescent lamps, fluorescent lamps or energy-saving lamps, are 50 ~ 60 Hz AC, most of the existence of different frequencies of strobe.
②, where the strobe of fluorescent lamps is a high-frequency flicker. Walking around under the light, there will be the phenomenon of ghosting. It may give people the illusion and cause problems.
③, stroboscopic phenomenon may lead to eye fatigue or damage to vision. Especially if there are children at home, the harm of this phenomenon is still relatively large.
(B) no ultraviolet radiation
Many traditional lamps and lanterns, more or less have varying degrees of ultraviolet radiation. For example, the more common incandescent lamps, fluorescent lamps or trichromatic fluorescent lamps, there are energy-saving lamps and so on. If you work or study under this kind of UV radiation light source for a long time, then there is bound to be a certain amount of UV radiation is absorbed. According to research, in a day of work and study under a light source of ultraviolet radiation, roughly equivalent to an hour in the sun.
Such lamps and lanterns generally also cause the following problems.
①, ultraviolet radiation will damage the human immune system if it exists for a long time. It may kill white blood cells and cause many diseases.
②, in fact, another very obvious point is that often in the light of ultraviolet radiation, it will make the skin dull and less white.
(C) no electromagnetic radiation appears
When we buy lamps and lanterns, we also have to pay attention to another point, that is, whether this lamp will appear electromagnetic radiation. Just like the fluorescent lamps, trichromatic fluorescent lamps or energy-saving lamps introduced above, because they are working in a high-frequency, high-voltage state, in this state, it is inevitable that there are different degrees of electromagnetic radiation. If we want to avoid electromagnetic radiation from lamps and lanterns, then try to avoid buying such high-frequency and high-voltage state of work lamps and lanterns.
Electromagnetic radiation of the lamps and lanterns, generally will also bring to trigger the following problems.
①, electromagnetic radiation may lead to palpitations, and may lead to insomnia, white blood cell reduction, etc.. In addition, it will lead to memory loss.
②, electromagnetic radiation will also damage the new Xie system, the heart and blood system, the nervous system and so on. It can cause damage to these systems. And these electromagnetic radiation damage, is the long-term accumulation.
(D) no glare hazards
There is a fourth hazard of the luminaire, which is the glare hazard. Many friends may not understand what is glare. In fact, it is very simple, is the uneven distribution of brightness, or is not appropriate. The presence of very extreme brightness contrast can lead to damage to human vision. To put it simply, the light from the lamps and lanterns are strong and weak, and the contrast is relatively obvious.
If the lamp has glare, it will generally cause the following problems.
①, our home lamps and lanterns long-term glare, it will make people look at objects can not see clearly, and will affect vision.
②, if we have children at home, glare lamps and lanterns will affect the development of children's eyesight. Because the glare in the environment will damage the retinal tissue of children.
③, for the elderly, glare may cause irreversible some damage, leading to a decline in visual function.
(E) blue light hazards
The last point to say to you is the existence of blue light hazards of lamps and lanterns. Now the home is basically LED lamps and lanterns, most of them have blue light.
And long-term blue light hazards, caused by the problem or a lot of:
①, will lead to visual fatigue. Not much time has passed, the eyes feel particularly tired, which is the blue light hazard.
②, serious will also lead to poor sleep. It can also damage the structure of the retina. These are some of the hazards caused to the human body.
Family shopping for lamps and lanterns, we should pay more attention to the health of the lamps and lanterns in addition to the style. In this article, home miscellaneous forum to introduce you to a few lamps and lanterns in the existence of problems. If these problems exist, it is unhealthy lamps and lanterns. So, when buying lamps and lanterns, ask these questions clearly. Try to choose to look good and healthy lamps and lanterns.
