At present, the myopia rate in society is getting higher and higher, and protecting eyesight is the most concerned issue for many parents. Compared with traditional table lamps, eye-protecting table lamps generally do not have blue light and strobe hazards, and use high-quality light sources to minimize eye fatigue, prevent myopia, and eye protection ability has been affirmed by ophthalmology experts. If you study or work under incandescent light for a long time Xi it will cause vision loss and even dizziness. I'm sure most of you have experienced this feeling. The eye-protecting desk lamp avoids this problem, not only protects eyesight, but also improves concentration. Moreover, the illumination is more uniform with the eye protection table light, and the lighting blind spot can be easily solved for some office Xi with a large area.
However, I found that the bigger the eye protection desk lamp market, there are many brands without professional technology precipitation to make eye protection table lamps and want to eat this wave of dividends, which can easily lead to everyone buying unsuitable eye protection table lamps, either the light is not soft, or there is a risk of eye damage.
Today, I will tell you how to buy a good-to-use eye-protecting desk lamp, and answer a few frequently asked questions.
1. Does the eye protection lamp have an eye protection effect?
The eye-protecting desk lamp has an eye protection function, and an electronic ballast is installed inside to turn the alternating current into direct current, increase the frequency to 30-50kHz, and achieve invisible strobe in the process of use.
And the table lamp applies three primary color phosphors to soften the brightness of the light, its light is close to natural light, the brightness can be adjusted, will not cause eye fatigue, so that the light range is larger, which is conducive to protecting the child's eyesight.
Second, what are the advantages and disadvantages of the eye-protecting table lamp?
Pros:
The luminous frequency of the eye-protecting table lamp is different from that of the traditional table lamp, which is low-frequency flickering, which will make people feel visual fatigue for a long time, while the eye-protecting table lamp improves the speed of the flash frequency of the table lamp, making it exceed the nerve induction speed of the human eye, so as to achieve the effect of reducing visual fatigue.
The eye-protecting table lamp is made of the best quality LED lamp beads, and is equipped with the latest technology and purple light excitation, which fundamentally eliminates the harm of blue light to the human body.
The color rendering index of high-quality eye-protection table lamps generally reaches more than RA90, which can restore the color of items well, and the color temperature does not exceed 4000K, which is closer to natural light.
The light guide plate of the eye-protecting table lamp can also effectively block the extension of glare, which can protect the child's eyes from direct light.
Cons:
Compared with ordinary table lamps, eye protection lamps are usually higher, which may discourage some consumers. Basically, this is also the main "shortcoming" of eye protection lamps. There are many brands of eye protection lamps, and the quality of the products is uneven. Some low-quality products may have problems such as unstable light and inaccurate color temperature. Therefore, when choosing an eye protection lamp, you should choose a reliable brand and product.
3. Purchase skills for eye-protecting table lamps
1. Illumination and uniformity
Illuminance refers to the amount of energy per unit area that can receive visible light, and the unit is lx or lux. In layman's terms, it is the brightness of the lighting within a fixed range!
The national standard GB T 9473-2017 "Performance Requirements for Desk Lamps for Reading and Writing Operations" divides the desk lamps for reading and writing operations into two grades: "A" and "AA" according to the illumination and uniformity of the lamp, and the "AA" grade has higher requirements than the "A" grade in terms of illumination and uniformity. Therefore, when we choose an eye-protecting table lamp, we need to pay attention to whether the illumination reaches "A" level or above.
Illuminance uniformity refers to the ratio of minimum illuminance to average illumination on illumination, the more uniform the light distribution, the better the illumination, and the illumination uniformity is also the requirement index of the "Performance Requirements for Reading and Writing Desk Lamps". Uniformity of a 120° sector area of 300mm 3;The illumination uniformity of the 120° sector area of 300mm and 500mm is also 3, which meets the national standard AA standard, and the closer the uniformity is to 1, the better.
2. Color rendering index
The color rendering index is used to reflect the quality of the color rendering of the light source, which is the degree of presentation of the real color of the object. If the color of an object under natural light is defined as Ra100, the closer the color rendering index is to Ra100, the better the true reproduction of the object;The lower the color rendering index, the worse the true reproduction of the object.
Color rendering index 》90, the better the color rendering If the color rendering of the artificial lighting source is poor, the comfort of the human eye will also be reduced, thus increasing fatigue. It is recommended to choose an eye-friendly table lamp with a color rendering index of RA95 or above.
3. Blue light and no flicker
If you shoot your phone lens at the lamp, if you notice obvious fluctuating streaks or obvious flickering, it means that the lamp has a severe flicker.
Blue light is not unfamiliar with eye damage, and long-term exposure to blue light can cause irreversible damage to the eyes. When choosing an eye-friendly table lamp, you must choose one that is free of blue light hazards and no strobes!
4. Color temperature
The so-called color temperature comes from a physical theory called "blackbody theory", which simply means that when an absolute blackbody is heated, it emits a certain amount of light, and as the temperature increases, the color of the light will also change.
The warm and cold range of light is suitable in the range of 3000k and 4000k, and reading and learning Xi at this color temperature is peaceful, and the learning efficiency Xi is also high.
Fourth, the eye protection table lamp is recommended
