What is an eye protection table lamp? Is it useful to protect the eye lamp?

Eye-protecting desk lamp, mainly when using the desk lamp, let people's eyes work and study under the lamp for a long time, the eyes are not easy to get tired, the use of optical principle data design, so that the light emitted by the lamp is more suitable for the eyes to work and study under the lamp The highest comfort;

Its principle: 1. The light color of the light is soft, and the desktop illumination of the light is set to about 215lx; 2. The light source is set to "no strobe", because our mains power is AC220V 50Hz The frequency of electricity will generally have the light according to the frequency of electricity "strobe", traditional incandescent lamps, energy-saving fluorescent lamps, all have this aspect of the strobe problem (now we can generally use a digital camera or mobile phone to shoot against the light source, there is a "strobe" phenomenon on the screen, it can be judged that there is a "strobe"), these problems generally do not affect the use, but, when working and studying under this light for a long time, Eyes are more prone to fatigue, and by solving this strobe problem, the eyes are less tired under light.

Note: Even if it is "eye protection", we do not recommend working and studying under the light for a long time, if it is really necessary, then it is recommended to let the eyes get rest or do eye exercises after a certain period of time, so that it is the real eye protection.

A real eye protection table lamp is useful because the eye protection table lamp itself has a lower strobe and a softer brightness because you. When you get home, you will definitely have to do your homework, and if you study on your own at school, you may have to study quietly for a while at homeEspecially on days like the third year of junior high school and the third year of high school, it is inevitable that you can't do without the desk lamp. <>

The choice of eye protection desk lamp is actually quite simple, your mobile phone has the function of taking pictures, turn on the camera of the mobile phone and remember that it is the original camera, and then aim at this desk lamp, if you find that the light source of this desk lamp is very stable, there is no kind of action at all, then this table lamp is basically not much of a problem in terms of strobe. If it is said that after illumination, this table lamp flashes wildly, but there is almost no difference with the naked eye, then this table lamp is not an eye-protecting table lamp. Because even if you can't see it with your naked eye, it doesn't mean that your eyes can't feel it.

And you have to know that you get what you pay for, whether the ** eye protection desk lamp will be 1 2 times higher than the ordinary table lamp**, and even more than an ordinary table lamp, maybe twenty or thirty yuan that eye protection table lamp, if you choose a little brand, we have done this kind of brand in the lighting field for a long time, and the eye protection table he made is basically no problem in terms of quality, but ** will be more expensive, maybe to seventy or eighty, and even one or two hundred The effect is undoubted, but it is really expensive,You don't want to be cheap, someone told you that you can buy an eye-protecting table lamp for 20 yuan, the risk is too high, not that it is completely impossible, but that the possibility is very small. <>

When things are done, try not to stay up in Taiwan at night, because even if the eye protection lamp has been for a long time, the intensity of its light is too high, it will also affect your eyes, and the intensity is not enough It will also affect your eyesight, so control the use as much as possible, uhThen rest your eyes to maintain long-lasting clear vision. This is crucial for everyone, because once the eye is nearsighted, it is almost irreversible except for surgery.

The eye-protecting table lamp has a certain usefulness, because the light of the eye-protecting table lamp is softer.

It is still very useful, and it can make your eyesight better and better, and you can protect your eyes. The effect is obvious.

Of course, it is useful, the eye protection table lamp can protect our eyes, and the effect is very large, the quality is also excellent, there are many families will buy eye protection table lamps for their children.

The eye-protecting table lamp is the real eye protection, no flicker - long-lasting reading, comfortable eyes; No glare - can be seen directly, without hurting the eyes; No radiation - protect eyes and brain, improve performance; No ultraviolet rays - not easy to fatigue, improve efficiency ·· Buy more domestic brands to come back to experience, the survival of the fittest for the child to really choose an eye-protecting desk lamp, such as @Guanjin @ can still be used as the first choice, it has been specialized in foreign countries before, and the technology may be relatively mature.

The working principle of a "eye protection lamp": increase the low frequency flash to the high frequency flash, this eye protection lamp adopts a frequency conversion electronic ballast, and the current frequency is increased from LED eye protection table lamp 50Hz to 30-50KHZ to make the human eye not feel the strobe, and the use of three primary color phosphors makes the light soft, so as to reduce visual fatigue. The strobe effect is an indicator of all fluorescent tubes:

The less noticeable the strobe, the better the lighting.

The working principle of another "eye protection lamp": turn the alternating current into direct current first, and use the direct current to light the lamp, so as to achieve basically no flicker and relieve visual fatigue. There is also no electromagnetic radiation. Typical DC lamps are LED lights and DC fluorescent lamps.

The table lamp that can protect the eyes.

I bought an Angel one for my son last year, and it feels very good, the light is very soft and eye-friendly.

A table lamp that can protect your eyes.

The Angels I bought for my son last year has been used for more than half a year and is very good.

It has some benefits for the eyes.

The eye-protecting desk lamp is a table lamp that has no sparkle, uses blue light, ultraviolet isolation technology, and uses a color rendering index of more than 94, and the eye-protecting table lamp can optimize the light source through LED panel technology.

Advantages of eye-protecting table lamp: the brightness of the decong is stable and flicker-free; The light is soft; The light is relatively uniform, and it is not a small point light source; Luminaires The lampshade is well designed and there is no glare (a bright spot visible to the eye).

Eye-protecting table lamp"It is mainly composed of two parts: the light source and the lamp. The lamp head is usually composed of a light source with good light quality, a lamp shade that can improve the uniformity of light distribution, and can reduce or reduce glare, and a driving circuit that provides current to the light source. In order to improve the angle and ghosting of the light source, the light source can be optimized through OLED panel technology.

The main types of eye-protecting table lamps are:

1. OLED table lamp: OLED lighting adopts low-voltage DC power supply, so there is basically no flicker, and there is no blue light ultraviolet damage, and it can be manufactured in a large area of OLED panels, which is a key research plan in China.

2. Electric heating lamp: The spectrum of ordinary incandescent lamps and halogen lamps (halogenlamp) is continuous, which is closest to the natural spectrum, so it is actually a kind of spectrum"Quietly jujube eye protection lamp"。

3. High-frequency lamp: The alternating current of China's power grid is 50Hz, and its voltage waveform changes 50 times per second, and the frequency of voltage amplitude changes twice the frequency of voltage waveform change, that is, 100 times a second.

4. LED lights: using adapters, lighting is mainly used in large-scale landscape lighting, and occasions with low requirements for light quality, low energy consumption, not suitable for high-eye environments, because the proportion of blue light components is too strong, and the eyes are easily damaged.

Whether the lamp is eye-friendly or not is related to many factors, such as the illumination of the lamp, the uniformity of illumination, blue light, strobe, glare treatment, whether the lampshade is transparent to the punch light, whether the angle of the lamp is adjustable, the angle of the user, and so on.

The main influence of long and circular table lamps may be the illuminance as well as the uniformity and glare of the illumination. The uniformity of illuminance and illuminance is judged to be off by the lamp, and glare is not only related to the lamp, but also may have a certain relationship with the user.

The illumination of the table lamp is generally required to be 300-500lx, with anti-glare process or setting. It is not possible to accurately understand the illuminance and uniformity of the lamp through the long strip or ring, which requires professional measuring equipment. And if you look at glare, you use a normal sitting position, you will not see the light source directly, and you do not feel uncomfortable, then the anti-glare of the lamp is okay, of course, accurate measurement also requires instruments and tools.

We can see whether the lamp has the relevant certification to understand whether it is eye protection, generally up to the national AA level to explain the illumination of the lamp, the uniformity of illumination is good, printed in line with the GB series standards is also a good reference, some desk lamps also provide in line with the visual work desk lamp standards, indicating the illumination of the lamp, the uniformity of illumination, anti-blue light, security, etc. meet the requirements, you can rest assured that the world uses.
