hello!各位宝爸宝妈们,大家新年好!
My baby is in the first grade of primary school this year, and has finally become a primary school student! Compared with the "edutainment" in kindergarten, I have begun to have some introductory homework tasks, such as: homework assigned by school, practice writing, doing various exercises and exercise books, etc......
In order to "all-round development", in addition to the daily cultural class learning, this year also enrolled in the art class in the Children's Palace, every time after returning home from the art class, the baby will also take the initiative to practice the painting skills taught by the teacher!
In addition to these tasks of writing, drawing, and drawing, "reading" should not be left behind! In addition to the various picture books and children's books at home, this year I also subscribed to several sets of extracurricular reading materials, such as "Mi Xiaoquan" and "Naturalist" magazine, to enrich the extracurricular reading every month.
Now the child's life is more colorful than when we were in primary school, and of course, it is more "busy"! It is precisely because after going to school, there are so many learning tasks, so the child's desktop space is used more and more frequently! In order to let the child better complete the learning task, we decided to create an efficient desktop learning space for her!
If you want to create a powerful desktop environment, consider tasks such as writing and doing homework!
A powerful table lamp can not only provide sufficient light, protect children's eyesight, make children feel comfortable when reading and writing, so as to improve learning efficiency!
With the development of science and technology, today's table lamps are different from the old-fashioned table lamps that we used to change the bulbs frequently when we were children, and their service life is very long!
Therefore, starting with a high-quality eye-protecting table lamp, it can often be used for more than ten years and is not bad! It can accompany children from the first grade of primary school to the third year of high school! Therefore, the investment in high-quality table lamps is still very worthwhile!
However, it is precisely because it takes many years to start at a time, so it is necessary to keep your eyes open in the process of purchasing!
"If you want to do a good job, you must first sharpen your tools", today, Brother 4 will come to smooth out the development process of the table lamp for you, as well as evaluate several hot-selling table lamps on the market, to see which one is the most suitable for your needs.
What are the problems of traditional table lamps on the market?
The development of table lamps has gone through the 1.0 (lighting only) stage, the 2.0 (eye protection, color temperature adjustment) stage and the 3.0 (AI intelligence) stage.
The traditional 1.0 stage table lamp only provides the lighting function, but does not have the function of adjusting the color temperature and eye protection. Sometimes it may be accompanied by problems such as flickering and uneven brightness. Long-term use can easily cause visual fatigue.
The table lamp in the 2.0 stage pays more attention to the eye protection ability of the table lamp. Added a variety of anti-glare, low blue light and low flicker eye protection functions. It can reduce visual fatigue and reduce damage to vision.
At present, the latest generation of 3.0 smart desk lamp not only has excellent eye protection ability, but also becomes more intelligent, which can protect children's eyesight, concentrate and provide learning data reports. Below I will choose three very representative styles, let you make a comparison!
From Table Lamp 2.0 to Table Lamp 3.0, what kind of table lamp do you need?
Today I am here to bring you three types of eye-care learning lamps, which represent the three different stages of the current development of table lamps from 2.0 to 3.0. Let's talk about this one first, Philips A5 eye protection lamp, this is an eye protection lamp that can only adjust brightness and color temperature, and does not have an intelligent detection function, it is a standard 2.0 eye protection lamp.
BenQ MindDuo2 Plus is an eye protection lamp equipped with an ultrasonic sensor that can intelligently detect sitting posture and has the function of automatically turning off the lights when leaving, which is a half-generation product between non-smart eye protection lamps and fully intelligent eye protection lights.
The Yuan Radish Light Wing Lamp is a table lamp 3.0 product launched by the home robot brand "Yuan Radish" of the famous artificial intelligence company SenseTime. It is equipped with an AI detection camera, which can provide comprehensive AI functions such as "AI dimming", "automatic shutdown when leaving the seat", "statistical analysis of learning concentration", "AI rest reminder", "sitting posture reminder", and "AI spotlight tracking" through AI visual analysis.
With the matching "Yuan Radish Light Wing Lamp" APP, it is easy to make AI adjustment and setting of the lamp, and in the digital report, you can easily get the statistical report of learning. Learn scientifically, be more efficient!
The professional attention research book "Deliberate Concentration" mentions a famous "attention flashlight" theory. In other words, human attention is like a flashlight, and you need to focus your main energy on the more important parts of the moment, so as to ignore the secondary problems. It can achieve a more efficient "flow" state.
Of course, in order to achieve concentration and concentration. There are a number of complementary techniques that can be employed. For example, use lighting or physical partitions to block out the interference of the outside environment. In the "focus mode", the AI vision is used to direct the spotlight to move, which can achieve the effect of "light moving with the book"!
As can be seen from the above comparison, with the great development of artificial intelligence technology, the ability of intelligent learning lamps equipped with advanced AI functions to assist learning has been greatly improved. It plays a greater role in the child's sitting posture and concentration.
Of course, as an eye-protecting table lamp, first of all, its own light ability needs to be excellent. So what is the actual lighting performance of these three lamps?
Comparison of Yuanradish Light Wing Light, BenQ MindDuo2 Plus, and Philips A5 Lighting/Eye Protection Capabilities
1. Comparison of appearance style and height adjustment
In terms of appearance, the Yuan Radish Light Wing Light adopts a "wing" shaped design that can be folded. It can be expanded to expand the lighting area. It can also be shrunk to increase the brightness of the core area. There are a total of 4 metal hinges in the body, so you can easily deform!
The overall shape is like a space plane that appears in a science fiction movie. The appearance is very good!
There is a tracking light in the middle of the light wing, and the base is designed with rounded touch buttons. You can adjust the switch, brightness, color temperature, switch between focus mode/regular lighting mode, switch prompt sound, etc.
Let's take a look at the look and styling of the BenQ MindDuo2 Plus. This table lamp adopts the shape design of 3 pivots + 1 ball shaft body. The main control buttons are located in the area in front of the lamp head, which is different from ordinary table lamps, this lamp has two big black eyes! In fact, these are two ultrasonic sensors, which can intelligently sense the distance of the human body, so as to remind children to maintain a good sitting posture.
Then let's take a look at the appearance and structure of the Philips A5. It has a linkage-style exterior with 5 hinges. The main control area is also located in the lamp head section. You can adjust the switch, brightness, and color temperature.
In terms of the measured adjustable height (subject to the headlight can be parallel downward), the adjustment range of the Yuan Radish Light Wing Light is 26-54cm, BenQ's MindDuo2 Plus is 26-70cm, and Philips A5 is 8-47cm.
2. Illuminance actual test + illuminance uniformity test
Next, let's test the degree of control, according to the current national AA standard of table lamp, it is necessary to achieve more than 500lx in a 500X300mm rectangular inner illumination, and the illumination uniformity is less than or equal to 3.
It needs to be within a 700X500mm rectangle, with an illumination of more than 250lx and a light uniformity of less than or equal to 7. So let's draw these two rectangles and see how the lighting actually works. The reference diagram is as follows:
2.1.1 Yuan radish light wing lamp 30cmX50cm range light test:
Center point = 1638Lux, left and right upper corner = 1274Lux, left and right lower corner = 1008Lux. Illumination uniformity = 1638/1008 = 1.625. Significantly more than the national AA standard!
2.1.2 50cmX70cm range light test of Yuan radish light wing lamp:
This time, the height of the lamp head was raised for a larger light range. The measured center point = 852 Lux, the left and right upper corners = 824 Lux, and the left and right lower corners = 499 Lux. Illumination uniformity = 852/499 = 1.71. Significantly more than the national AA standard!
2.2.1 BenQ MindDuo2 Plus 30cmX50cm range light test:
The measured center point = 1307 Lux, the left and right upper corners = 943 Lux, and the left and right lower corners = 970 Lux. Illumination uniformity = 1307/943 = 1.39. Significantly more than the national AA standard!
2.2.2 BenQ MindDuo2 Plus 50cmX70cm Range Light Test:
The measured center point = 1287 Lux, the left and right upper corners = 747 Lux, and the left and right lower corners = 599 Lux. Illumination uniformity = 1287/599 = 2.14. Significantly more than the national AA standard!
2.3.1 Philips A5 30cmX50cm range light test:
The measured center point = 627 Lux, the left and right upper corners = 340 Lux, and the left and right lower corners = 529 Lux. Illumination uniformity = 627/340 = 2.14.
2.3.2 Philips A5 50cmX70cm range light test:
The measured center point = 701 Lux, the left and right upper corners = 266 Lux, and the left and right lower corners = 415 Lux. Light uniformity = 701/266 = 2.63. Exceeds the national AA standard!
After the above tests, the following data table was obtained. In terms of maximum light intensity and light uniformity. Yuan radish and BenQ are relatively good, significantly exceeding the national standard AA standard. The Philips A5 slightly exceeds the national standard AA standard. In this link, it is recommended to start with the Yuan Radish Light Wing Light and BenQ MindDuo2 Plus.
3. Comparison of color temperature adjustment functions
Generally speaking, natural white light around 4000K is more suitable for daily reading for a long time. The warm white light around 3000K-3300 is the softest, which is suitable for bedtime. The light of about 5000-5300K (positive white color temperature is about 6500K) is relatively cold, which can remind people to stay awake, suitable for short-term concentration, and not suitable for long-term reading.
From the perspective of reading and writing comfort, the table lamp with a large color temperature adjustment function can get a better experience during use.
Among these three table lamps. The color temperature of the Yuan Radish Light Wing Light can be adjusted from 3000-5000K, the color temperature of BenQ MindDuo2 Plus can be adjusted from 3300-5300K, and the color temperature of Philips' A5 can be adjusted from 3000-5000K. Both can provide a color temperature range from white to warm yellow light.
From the point of view of adjustment method, Yuan Radish is the base slide to adjust the color temperature + APP adjustment is more convenient; BenQ is adjusted by the physical knob of the lamp head;Philips is the touch adjustment of the lamp head。
4. Comparison of anti-glare capabilities
The so-called glare is the bright light that is too prominent in some areas emitted from the lamp, in order to prevent the occurrence of glare, it is necessary to use an anti-glare plate or a matte lampshade to cut the light, cut into countless uniform lights, so as to avoid the appearance of glare.
Let's first compare the design of the anti-glare panels of the three table lamps. These images were taken with ND1500's filtering filter. It simulates an effect similar to "glass + ink to watch a partial solar eclipse". On the whole, the anti-glare effect of Yuan Radish and Philips is better, the entire luminous area has been connected, and all areas are emitted evenly, and the specific number of lamp beads can no longer be seen. BenQ's, on the other hand, clearly shows the structure of the 14 lamp beads inside, and the light is not sufficiently cut and dispersed.
Let's take a look at the microstructure comparison of anti-glare panels. From the microscopic structure, the effect is clear at a glance. Yuan Radish and Philips use anti-glare plates that are common on high-end eye protection lamps, using the principle of prism to cut the light into uniform small streams of light. BenQ, on the other hand, uses a matte lampshade similar to ground glass, which does not have the effect of cutting all the light evenly.
In this regard, the performance of the hexagoprism structure is relatively better.
Let's take a look at the difference between the glare of these three desk lamps when they actually read a book. Generally speaking, mimeographed picture books and color books are more likely to see glare, but it does not mean that books made of other materials will not produce glare.
If the light is not uniform enough and the glare is strong, watching for a long time will cause visual fatigue. You can see it. Compared with ordinary table lamps, the anti-glare ability of these three models is relatively good. When viewing the picture books of Yuan Radish and Philips, the light is more evenly distributed. Under BenQ lighting, there will be a slight over-brightness area.
5. Comparison of color rendering index and color rendering ability
Color is the visual feedback that light hits an object and reflects back into the eye. So, even if it's the same item, its color will be affected by the light. Lighting with a high color rendering index can make colors richer and restore more realistic colors.
In my daily photography work, I am exposed to more lights, and I use several 300W headlights in my daily shooting work, which is a light with more than 95% color rendering, which is more than twice as expensive as the low color rendering light of the same wattage!
In the same way, whether it is a child painting or reading a color picture book, the light with a high color rendering index can make the details of the picture more vivid and the color more restored!
Judging from the parameters, the nominal parameters of these models are above 95. It belongs to the high color rendering light. In terms of the actual shooting effect, the difference is not big, the colors of Yuan radish and BenQ are more distinct with the naked eye, and the boundary between the color cards is clearer, while the boundary between Philips relative color cards is not so clear.
Judging by the effect in terms of drawing. These three are relatively in place for the color of the color pencil and the color presentation of the picture.
6. Comparison of anti-blue light functions
Harmful blue light can reach the retina, causing retinal cells to shrink or even die, which can easily cause macular degeneration. Therefore, when you start the eye-protection desk lamp, you must pay attention to the blue light protection effect of the table lamp.
There is a special coating on the anti-blue light glasses, and the harmful blue light (harmful blue light with a wavelength of 415~455nm) and a part of the blue light cannot pass through the lens, so the reflected light of the lens will appear blue.
The picture above shows the effect of placing gaming glasses on a ceiling lamp without any eye protection function, and the reflection of the coating. It can be seen that in addition to the light blue light, there are many blue-violet rays on the edges that have a certain effect on the eyes.
These three are RG0 exempt anti-blue light eye protection lights, let's take a look at the actual anti-blue light effect.
After actual viewing and comparison, these three models show light blue light, and there is no particularly obvious blue-violet light reflection like ordinary ceiling lights. It performs well on blue light protection.
Summary:
After the above comparison, I have put together this table for you. You can refer to this table to make a purchase. Among these models,Yuan radish belongs to the AI visual blessing of the table lamp3.0Generation product,Since it can realize a variety of reminder functions,It can also generate learning reports with APP,It can also support the effect of light moving with the book。 BenQ belongs to the 2.5 generation of table lamps with ultrasonic sensor intelligent reminders, and Philips A5 is a standard 2.0 generation eye care product.
In terms of price, the Philips A5 has the best price, but it is relatively weak. From the perspective of comprehensive strength, the Yuan radish light wing lamp is more cost-effective. In terms of lighting capabilities and uniformity, both the Yuan Radish Light Wing Light and the BenQ MindDuo2 Plus are strong enough. In terms of anti-glare, the structure of Yuan Radish and Philips is better. In terms of height adjustment, the BenQ range is larger.
Overall, I recommend you to get this Yuan Radish Light Wing Lamp. Not only is the lighting better, but it's also smarter. It can better help children to devote themselves to learning, concentrate, maintain a good sitting posture, is a very futuristic product, if you are also buying a children's eye protection table lamp recently, you can buy it!!
