What to save, electricity or eyesight of the child?

 


An article on the negative impact of energy-saving lamps on child health. Proper lighting of the workplace of the student.

Solving the problems of organizing a student’s workplace is of paramount importance because schoolchildren, especially elementary school students, spend a lot of time at their workplace. After all, they not only prepare lessons, but also fill their leisure time with drawing, coloring and other entertainments.

The main element of the student’s workplace, ensuring its convenience and practicality, of course, should be recognized as general and desktop lighting. There are a lot of options for such lighting now, and advertising and cunning managers are especially persistent in using it as such energy-saving lamps.

Praising the advantages of energy-saving lamps, both manufacturers and distributors of these products, mainly, if we ignore various marketing tricks, dwell on two points that attract us.

The first is a small consumption of electricity for work, guaranteeing a reduction in the cost of lighting the entire home. The second is the long life of the energy-saving lamp. In general, compared to conventional incandescent lamp, to which the older generation has long been accustomed, an energy-saving lamp, is simply a wonderful achievement of modern science and technology.

The question that interests us concerns the rationality of such savings. And the rationality of saving should, first of all, imply an objective understanding of the question of what, besides benefit, will bring us using this or that thing. Energy-saving lamps in this case also should not be an exception.

The first thing that parents of a first grader will encounter and what parents of schoolchildren already know is the significant burden created by the study on the child’s eyesight. The process of teaching children is inextricably linked with reading, drawing, cutting, etc. actions that are necessarily carried out at the desktop using lighting.

Constant tension of the eye muscles of the child leads to circulatory disorders in the organs of vision and premature fatigue. In order to smooth out this negative effect, and not to strengthen it, it is necessary to properly organize the lighting of the student’s workplace.

Specialists in the field of occupational health and safety noted that the energy-saving lamp provides bright white lighting, which for a person’s vision is not only an additional burden, but also has a negative effect on the eyes, significantly bringing the eye muscle fatigue closer. This influence is especially pronounced when exposed to the organs of vision of a primary school student.

Since Soviet times, it is recommended to use, along with general room lighting, desktop lighting of a child's workplace with yellow light medium brightness, which is designed to provide a standard incandescent lamp with a power of 60-100 watts.

In addition, the energy-saving lamp flickers constantly during operation. Such flickering, although invisible to the human eye, has a negative effect on vision, estimated by modern ophthalmologists, as a factor that gradually impairs vision.

Specialists in skin diseases, as a result of research, also found a connection between the risk of developing such diseases and the emission of bright white light that comes from an energy-saving lamp. Does not honor the energy-saving lamp and the fact that it contains elements of mercury that ensure its operation as light source.

Thus, do not rush to chase the fashion and popularity of energy-saving lamps when choosing a source of illumination for the workplace of children of primary school age, do not save energy and reduce the cost of acquiring several ordinary bulbs instead of one energy-saving one during the school year, since the health of your child may be the price for such savings.

    in the text of the article, by energy-saving light bulbs you mean CFLs, and yet, for example, halogen bulbs are also energy-saving

    Energy-saving luminescent for E27, E14 and classic with electronic ballasts "flicker" at a frequency of kilohertz. The eye is not distinguishable. The girl probably talks about some old lamps, with chokes.

    The "elements of mercury" sounds quite funny in itself. Mercury in the energy saving unit of a milligram, while the medical thermometer - 2 ... 4 grams of mercury. Naturally small content does not negate the fact that they should not be broken up and must be disposed of correctly. Mercury in a lamp is safe for health. Mercury vapors that have fallen into the environment when a single lamp is damaged are practically safe, just ventilate.
     
    "Radiation of bright white light" - the girl does not seem to know that the spectrum of fluorescent lamps is, as it were, different. That bought, and shines.

    The main harm of fluorescent lamps (LL) is not in flickering, because electronic ballasts operate at dozens of kilohertz, which makes no sense to flicker.
    The spectrum is harmful - in fluorescent lamps it is ruled, and in the good old incandescent lamps (LF) continuous to what our eyes are designed - such a spectrum is in the Sun! Not in vain in SNiP 23-05 "natural and artificial lighting" the lighting standards for fluorescent lamps are one step higher than for incandescent lamps.

    In most cases, desktop fluorescent lamps use compact fluorescent lamps with a two-pin base that do not have a built-in ballast. The presence or absence of flickering of the luminous flux depends on the lamp, or rather, on which ballast is used there - electromagnetic or electronic. By the way, electronic ballasts in table lamps are not such a common thing. You can see the catalogs on the Internet. Everywhere there, the presence of electronic ballasts in luminaires is indicated as an advantage of individual models. Therefore, Angelica in her article is completely right. Many luminaires with fluorescent lamps (especially cheap models) spoil the vision.

    Halogen lamps are not energy-saving, as they are close relatives of incandescent lamps in terms of their arrangement and physical processes of light generation. The luminous efficiency of halogen lamps is only 13 - 25 lm / W.

    According to SNiP 23-05 "natural and artificial lighting", the illumination standards for LLs are one step higher than for LLs, not because of differences in spectrum, but primarily because the incandescent lamps have a very low light output and provide the necessary (normalized) illumination at the same cost would be much more complicated, i.e. all because of the banal cost savings. This, by the way, is as an explanation in Knorring’s handbook.

    The main thing that is convenient is that it is easy to integrate a line of LEDs into the fixtures from an "energy-saving" table lamp. The new LEDs from Nicia, Kingbright and other equally well-known manufacturers give a fairly pleasant warm white (approx.2300K) light with power up to 3 W / module, and at a price they are becoming more affordable. For local lighting - this is it! (as opposed to general). My children already have such lamps of their own manufacture, one of the 11-watt “housekeepers” (a substantial alteration was required, a modified charger from a mobile phone in the current stabilizer mode was installed instead of a throttle), the second from a desk with a halogen (which is much easier: in the original The version had a 12 V transformer, it took only 3 LEDs of 1 W each and a driver, thanks to which it was possible to implement a dimmer at the same time). There is an idea to add a strip of RGB LEDs to the line to set the desired shade of light.

    About the "extreme high cost" of LED lamps - this is a marketing tale for amateurs. Komplektuha for these has long been quite "tough" to the average consumer. I easily riveted luminaires from the converted halogen ones, now I’m thinking about how to rationally use parts from dead and defective energy savers with standard (E14, E27) socles: they are often given to me in batches for free. But the finished products really "bite": at the mere mention of LED products, sellers roll their eyes and show price tags with a bunch of extra decimal places.

    Perhaps the only real drawback of LEDs today is a weak overall luminous flux. With directional glow, their brightness is even higher than traditional light sources. However, when scattered, it is too quickly lost. Hence the "high price": to replace, say, 18-W LDS, about 200 pcs of LEDs must be crammed into the same pipe!

    Conclusion: use halogens and LDS for general lighting (which is not always necessary every day), and for local (desks, night lights, spotlights, etc.) use LEDs. Safer for the eyes (especially for children!), And for the pockets!

    Energy-saving lamps are not really good, but continuous only harm. The light emitted by energy-saving lamps has a hard spectrum. Despite the fact that we are hung up with noodles that there are energy-saving lamps with a soft spectrum, there are more and more children with impaired vision and this is direct statistics of children's hospitals.

    AlenkaWhat is a "hard and soft spectrum"? Vision spoils not the spectrum, but the flicker of two-pin compact fluorescent lamps connected using an electromagnetic ballast. In order not to spoil the eyes of children, buy table lamps with pastrons for incandescent lamps, and use the usual compact fluorescent lamps (with built-in electronic ballasts in the base), preferably a warm white color (2700K).

    The main eye strainers are the intermittent "non-solar" spectrum and flicker. All these CFLs pay off for at least a year, if they do not burn out, but shine like the devil.
