Eye health is essential for a child's learning as they grow up, and a good lighting environment has a profound impact on vision development.
Nowadays, children's "world" is very much, and in addition to spending time on school homework every day, there are many extracurricular homework to complete. Without a good eye protection lamp, vision will only increase year by year. Therefore, for the sake of children's eye health, eye protection lamps have become one of the essential tools for learning.
There are quite a lot of learning lamps on the market, although many of them are also in the name of eye protection, but not all of them are suitable for children. So how to choose an eye protection lamp?
When we enter the product page, we will face various professional terms and parameters such as color temperature, color rendering index, blue light, illuminance, etc., which is really head-catching, and then the first idea is to choose a big brand without a brain, although this practice will not step on the big pit, but you will be able to choose a cost-effective product.
Here I recommend focusing on illuminance, color rendering index, color temperature, and safety lighting.
Illuminance and color rendering index
Whether it is bright enough should be the key to our daily evaluation of the usefulness of this lamp. This brightness usually refers to the brightness of the light source, which refers to the degree to which the light emitted or reflected by an object is perceived by the human eye, so the brightness will also vary from person to person. But the lamp doesn't say how bright it is, but the word illumination.
Illuminance is the abbreviation of light intensity, which refers to the luminous flux of visible light received per unit area, and is measured in lux (Lux or Lx). It can be seen that illuminance is not equal to brightness.
Judging from the standard value of educational building lighting specified in GB/T50034-2024 "Architectural Lighting Design Standard", the illumination standard of the classroom and reading room should reach 300lx, and the unified glare value UGR should not be greater than 19, while the desktop of the art classroom should reach 500lx, which shows that the requirements for illumination will be higher when painting creation.
Although the art classroom desktop requires that the color rendering index Ra should not be lower than 90, it is recommended to give preference to products with a Ra value of 97 or more. As the value approaches 100, the object under the light will take on its original color. In this way, the child's ability to distinguish colors can be improved, and the eyesight can be better protected.
Color temperature and safety lighting
The lower the color temperature value, the warmer the light will be, and vice versa, the colder the light will be. Different color temperatures can give people different feelings, cold light is suitable for work, and warm light is suitable for reading.
For the human eye, between 3000K and 4000K is the most comfortable, there will be no obvious irritation and injury, and it is suitable for working or staying for a long time.
It is the basic requirement for lamps and lanterns to have no blue light hazards and no screen flicker hazards, and it will be more secure to choose products from regular manufacturers in this regard. Of course, if you want to talk about the specific parameters to pay attention to, then first look at whether there is TÜV SÜD certification testing, followed by UGR unified glare value.
Yeelight立式学习灯V8 Pro
In order to protect my child's eyesight, I have been using a children's eye-protecting desk lamp, but there are always unsatisfactory things. Later, after seeing the appearance of the vertical learning lamp, I found that this kind of lamp, also known as the "big street lamp", can actually meet all my requirements for the learning lamp.
After a comprehensive comparison, I started with Yeelight's V8 Pro. The main reason why I consider his home is that several ceiling lamps in the home are of this brand, and the lamps and lanterns are very cost-effective.
So after changing to Yeelight learning lamp V8 Pro, how much has it changed children's learning? Next, let's talk about the advantages and disadvantages of this lamp.
Provide adequate lighting
After lighting up the Yeelight V8 Pro, open the book with your hand. The picture under the light is clear and the colors are natural. Although there will still be some reflective phenomena on coated paper, the visual sense is not strong, and it is not used to find the angle of reading.
The handwriting of the practice notebook is also very clear, there is no paragraph difference between the top and the end of the text, the light range is wide, the brightness is uniform, and the reading experience is very easy for the eyes.
Yeelight learning light V8 Pro adopts the upper and lower light-emitting surface design, with a total luminous flux of 13000lm, an irradiation area of 20m², an average illumination of ≥ 2109 lux in the central area, and an average illumination of 2045 lux in the total area, with very high parameter values.
So maybe you want to say that the official data is for reference only, is there an actual lighting value for users?
First of all, we choose a handheld optical spectrum detector, and then slowly approach the Yeelight learning lamp, and stop when we find a close illuminance of 2200 lux, and measure the distance between the current position and the lower light panel by about 120cm. When we move to a distance of about 100 cm, the illuminance rises to 4200 lux, and when we get closer to only 10 cm, the illuminance has exceeded 20000 lux.
Considering that I am not using professional equipment, I also need to consider environmental factors, so numerical deviations are inevitable, and the above is for reference only. However, judging from the measured spectral data, the blue light peak of Yeelight learning lamp V8 Pro is low, and the display index (Ra) has also reached more than 98.4, which can restore the real color of the object to the greatest extent.
Next, we measure the distance from the ceiling light to the desktop, which is about 160cm, and then mark 30 points in the 100x80cm area of the desktop, and finally record the current illuminance value with a spectrometer.
In terms of numerical values, the current maximum value is 767lux, the color temperature reaches more than 6200, the color rendering index (Ra) is only about 81, and the blue light is quite high, which is not very qualified for learning use.
Next, turn off the overhead light, move the Yeelight V8 Pro next to the edge of the desk, and rotate the brightness to the maximum. Because the height of the learning lamp is not adjustable, it is fixed at 205.5cm, so the distance from the lamp board to the desktop is 125cm.
Judging from the values fed back by Yeelight learning lamp V8 Pro, under the premise of 120cm distance, the illuminance in the center reaches 1956lux, and the corresponding illuminance values on both sides are also close, which shows that its advantages of uniform illumination are obvious.
If you draw a range with 5 times the national classroom lighting standard of 300lux, then the illumination area contained in Yeelight learning lamp V8 Pro reaches a radius of 40cm, and even the far end has an illumination of 1277lux, which still meets the requirements of national AA level.
When tutoring homework, it can meet the needs of two people to sit side by side, and keep the light and sufficient coverage, which can easily cope with the 120CM desktop.
At the same time, thanks to the joint action of the upper and lower light sources, and with the help of the diffuse reflection principle of the wall, the ambient light lighting is compensated and the hand shadow interference is reduced. For children's writing and reading environment, Yeelight Learning Lamp V8 Pro can provide an effect close to that of a shadowless lamp, and it will not be completely black under the wrist.
It should be noted that if the original lamp is not very good, then it is not recommended to turn it on together. For example, when I turn on the ceiling light and the Yeelight at the same time, although the illuminance rises to 2700, the color rendering index (Ra) decreases and the blue light also increases, which is why mixed lighting is not recommended.
The color display effect is excellent
Color temperature will affect mood, and the right color temperature has a "hint" on reading habits, work efficiency, and people's mental state. The color temperature of Yeelight learning lamp V8 Pro is a fixed value of 4000K, which is a color temperature value that is more suitable for long-term work and study.
Compared with the desk lamp that can be adjusted in multiple stages, the color temperature of the Yeelight learning lamp V8 Pro is indeed a bit "monotonous". But in terms of user experience, stability will be better than adjustable.
The 4000K color temperature is often referred to as natural light, which is between cool white light and warm white light, which will give people a soft feeling and will not cause excessive irritation to the human eyes. When children learn at this color temperature, their mood will be more stable and their learning efficiency will be higher.
In addition, the light environment quality of Yeelight learning lamp V8 Pro reaches 98, the display index is as high as Ra99, and the color quality and color reproduction of the light source are quite high, far exceeding most current desk lamps.
The intuitive feeling is that when reading picture books or albums, the contrast between dark black and dark blue is obvious, and there is no bias towards dark yellow or gray white, which can present the real color "world". And the lines of objects and people are clearly outlined, and they will not be blurred.
It has a great advantage in cultivating children's correct color discrimination ability and increasing interest. Coupled with RG0 anti-blue light hazard certification, no video flicker, unified glare value UGR<10, no need to worry about the burden on your eyes, just right for children in the growing stage.
Break the traditional placement structure
I believe that many people are like me, when they first see the structure of the large street lamp, they will have such a question, such a large volume, is it not a problem to place?
The Yeelight Learning Light V8 Pro looks tall, and the base size has reached 485.5x330mm, but the actual base is only 10mm thick.
The thin base makes it ideal for tucking into the bottom of tables or corners, such as the bottom of a sofa, without taking up the aisle or interfering with daily activities. And it has a 15° front and rear anti-tipping design, but the stability is very high, and the weight distribution is reasonable.
Compared with traditional lampstands, large street lamps have the advantage that they do not take up space on the desktop. We don't have to clean the table to make room for the table lamp, just place the Yeelight Learning Light V8 Pro on the side of the table and it will illuminate the entire table like a ceiling light.
In addition, the head of the Yeelight learning light V8 Pro can be rotated and adjusted by 90°, and the area coverage is more flexible, whether it is placed upright or sideways, we can find the angle to illuminate the entire desktop.
It is worth mentioning that the base is equipped with carrying wheels, when we need to move the Yeelight learning light V8 Pro, we only need to tilt it back about 40°, and then we can push it to move. The details are small, but they're functional.
Support a variety of adjustment methods
If you don't use the APP, the Yeelight learning light V8 Pro needs the touch keys on the light pole to cooperate with the wireless remote control, and then you can complete the switch on and off the lamp, adjust the brightness of the upper and lower light panels, turn on AI adaptive dimming and timing adjustment.
You may want to ask why there is no light brightness adjustment on the light pole? In fact, this is also out of consideration for children's "hyperactivity", and dimming must be in the hands of parents to feel at ease, so as not to change the light source when they get it.
Yeelight Learning Lamp V8 Pro also supports Mi Home APP access. The function includes all the adjustment functions on the remote control, and you can also use Xiao Ai for voice control. And it also adds a smart scene to share the control of the lights.
Through the linkage configuration of Mi Home, we can also achieve intelligent one-click opening. For example, after being linked with the human body sensor, it can achieve the function of turning on the lights when people come and turning off when people go.
Personally, it is recommended that you can adjust the "switch gradient duration" for a few more seconds in the settings, so that when the light is turned on and off, the light will present a process from dark to bright, from light to dark, giving the eyes an adaptation process and protecting their eyesight. In short, Yeelight learning lamp V8 Pro has a lot of gameplay, even the elderly and children can find their own control methods.
Not too obtrusive appearance
The packaging box of Yeelight learning light V8 Pro is relatively large, and the weight reaches 18kg, without the help of the courier brother, it is indeed difficult to move upstairs.
The protective measures inside the box are in place, not only with thick sponge filling, but also with tailor-made slots for each object.
The contents of the box look quite a lot, in addition to the lamp head, base, remote control and manual, the rest is the aluminum upper light pole, aluminum lower light pole, power cord, fixing screws and installation kit.
Among them, the remote control is stepless adjustment, the rotation friction resistance is small, and the feel is relatively smooth. The advantage of wireless is that it is easy to control and can be placed anywhere on the desktop. And because it has a white appearance, it looks quite textured.
The largest size inside is the lamp head, with a length and width of 600x380mm, a thickness of 30mm, and a double-sided luminous design with a total luminous flux of 13,000lm.
The lower and lower light source is a full-face light-emitting plate, which adopts a new generation of full-spectrum lamp beads, with a luminous flux of 4200lm, and uses a diamond-crystal soft light design to avoid direct light source into the eye.
The upper light source is a two-stage structure, and the overall light transmission is 8800lm, which is used to supplement the ambient light. The upper and lower light sources can be controlled independently by the remote control, for example, when only the upper light source is turned on, it can be used as a night light to accompany sleep.
The hinge part of the lamp head can support 90° rotation, and the coverage area is more flexible, which belongs to a more user-friendly design.
At the end of the crossbar is the terminal block, which uses a 6-pin structure. Because the cable is wrapped in rubber, it is not too soft after bending, so pay attention to the direction during subsequent installation.
The two aluminium poles are square in shape, with thick walls and yellow labels on the outside to distinguish between the top and bottom. Among them, the lower light pole will be equipped with a power switch, and the connecting terminal is a female port, and the two ends of the upper pole lamp each have a connecting terminal, which is 6 pins and 2 pins respectively, with anti-plugging design.
Because the Yeelight Learning Light V8 Pro is a split placement, it needs to be assembled by the user. The steps of installation are not difficult, and there is also a labor-saving structure "hidden" in the box.
First, take out the inner lining of the box, insert the side of the lamp head into the groove of the inner lining, and then connect the terminal of the lamp head crossbar and the upper light pole.
Raise the upper pole with the same pad that placed the accessories earlier, so that we can screw the 4 screws provided in the accessory bag and fasten the cover of the crossbar of the lamp head. Here pay attention to the direction of the light pole, the yellow label is on the back, and the touch button is on the front front.
Set aside the assembled lamp head and upper light pole and replace it with a base and stand in the groove at the other end of the inner lining. Again, the pads are used to raise the lower pole so that it aligns with the 4 screw holes in the base. Tighten the fixing screws in turn to complete the assembly of the base and the lower light pole. It should be noted that the lower light pole also has a front and back, and the power jack with a yellow label is the back.
Finally, connect the inner terminals of the upper and lower light poles, then plug the upper light pole with the lamp head into the lower light pole, and complete the screw hole lock at the connection, so as to complete the installation process of Yeelight learning light V8 Pro.
After all the installations are completed, the overall height of the Yeelight learning light V8 Pro reaches about 205cm, and the appearance is relatively simple. Although it is a large street lamp with a large base + square light pole, it does not feel too abrupt when it matches the interior decoration.
Because the lower position on the back of the light pole is the power interface and the main power on/off key, it is recommended not to lean too much against the wall when placing it, so as not to reach it when the power is turned off.
Is it worth starting
As a "big street lamp" style eye-protection lamp, the actual effect of Yeelight Vertical Learning Light V8 Pro has far exceeded my expectations. After getting started for a while, I found that this kind of eye-protecting street lamp with a vertical structure actually has incomparable advantages over table lamps.
The dual-luminous surface is equipped with AA illumination, which not only ensures the brightness of learning, but also makes up for the ambient light, and achieves an almost shadowless writing atmosphere. The high display index of Ra99, TÜV SÜD certification test, no video flicker, no blue light hazards, and passed the glare test, reading is not dazzling, and it is a good protection of children's vision health.
In addition, Yeelight Learning Light V8 Pro has an AI adaptive dimming eye protection system, which can compensate for ambient light through intelligent sensing to avoid the illumination of the desktop from flickering and dimming due to environmental changes, ensuring the stability of the illumination of the desktop and effectively alleviating visual fatigue.
In terms of appearance, the simple design and delicate paint technology make the Yeelight Vertical Learning Lamp V8 Pro easier to integrate into various home environments. If there is one point that can be improved, the overall height of the light pole is not adjustable, and there is still room for improvement in the compatibility of the home environment.
