What kind of light is used to protect your eyes when reading at night?

What are the best lamps to choose for study? Which can protect the eyes

? A correct choice of lamps, can give us a good atmosphere for learning, but also to protect our eyes from harm, in the study we first is to choose the right lamps, then the study to choose what lamps good? Which can protect the eyes?

From the book we can find answers to the unknown, see nature can also appreciate the beauty of the mountains and rivers, to take us to see these must need a lamp, so what kind of lamps in the study is good?

Study lamps and lanterns selection, should be to adapt to the nature of the work and learning needs position. More suitable for the selection of a reflector with the lower part of the opening of the direct-type desk lamp, desk lamp light source is more commonly used incandescent lamps and fluorescent lamps. Incandescent color rendering index is relatively high, fluorescent lamps are more efficient, they have their own advantages, according to their own preferences to choose to use the lamps.

The height and brightness of the lighting in the study are very important. Desk lamps using incandescent better, wattage selection is about 60W, if too dark damage to eye health, too bright and harsh on the eyes is not good.

Additionally, the writing desk and table top size and height are more important, the size of the table top can be based on the hand range of motion and work needs to decide. Therefore, in the purchase of study lamps and lanterns should not only consider the effect of decoration, but also consider the function and rationality of the light.

Incandescent desk lamps used on the desk, the light can not be too strong, the location of the desk lamp is best placed in front of the left, so that you can avoid glare, to achieve the effect of vision protection. Secondly, is the location of the lampshade, also need to be adjusted to the most appropriate position, the distance between the human eye and the lamp should be about 40cm, from the light level distance of about 60cm, and can not see the inside of the lampshade, lampshade of the lower part of the best and eyes flush or lower than the eye, do not let the light directly or reflected to the human eye.

See the choice of lamps in the study, we can not only for the sake of aesthetics, but also from the standpoint of eye protection to make a choice,

So what is good for the eyes?

From the point of view of eye protection considerations, the study of the large area of lighting can be used ordinary fluorescent lamps, because the efficiency of fluorescent lamps than incandescent lamps to be high, that is to say, the same power, fluorescent lamps than incandescent lamps to be much brighter;

As for the desk and the computer table for local illumination that is to read and write with the lamps, it is recommended to use the electronic ballast type of compact fluorescent lamps or energy-saving lamps, because with electronic ballasts lamps or energy-saving lamps, the lamps are not only for aesthetic purposes, but also to protect the eyes from the position to choose. Because the electronic ballast lamps (the actual working principle and fluorescent lamps is similar) or energy-saving lamps work at a higher frequency than the ordinary 220V AC frequency is much higher, with such a high frequency of current lighting lamps, it eliminates the human eye on the visual 50Hz AC "strobe effect", to protect the eyes have the benefit of.

Generally speaking, the desk lamp, with small fluorescent lamps or energy-saving lamps, its power has 13W-20W between the words, it is enough to be very energy-saving, if you use ordinary incandescent light bulbs,

40W of power and its brightness does not feel comfortable. The color issue of course should be the best white, because only pure white will not change the environment and the object's own color.
