In today's fast-paced life, we pay more and more attention to eye health, and eye protection table lamps have gradually entered thousands of households. At this time, an important question is placed in front of us, that is: do you need to buy expensive eye protection table lamps?
At present, the eye-protecting table lamps on the market are cheap for only a dozen yuan, and expensive ones are thousands or even tens of thousands. What is the reason for such a large price gap? Is it true that a high-priced product necessarily has the most advanced technology and the best eye protection performance?
In fact, whether an eye-protecting table lamp is good or bad cannot be judged simply by the price. Affordable products, as long as the quality is good and the data is up to standard, can also have a good lighting effect; Among the expensive products, there are also many people who fish in troubled waters, which can be said to be imaginary.
However, this does not mean that we can just buy some products that are too cheap. Like those more than a dozen eye-protecting table lamps, it is okay to use them when they are placed at the head of the bed at night, but it is absolutely impossible to use them for children to learn to use, because there are many problems.
First, the problem of cheap table lamps
1. Safety is worrying
Too cheap products, may not even be willing to use the shell well, either easy to break, or will produce toxic gases at high temperatures, or will leak electricity, which is no longer a problem of hurting the eyes, but directly harming personal safety.
Some products have acceptable shell quality, but they will produce strong reflections when used, which will cause damage to children's eyes.
As for the safety of the light source, not to mention, blue light, strobe and other problems, each of which is a major factor that hurts the eyes.
2. The data is not up to standard
Many cheap table lamps are directly unqualified, or only part of the data is qualified, and then deliberately do not mark those unqualified items, which will make some consumers who do not understand to buy.
There are also some products that "seem" to be qualified, but in fact, there are some false standards, or data erases, but they are qualified under certain conditions.
3. It is inconvenient to use
For example, some products do not support the adjustment of the angle of the lamp body, or the adjustment angle is too small, and it cannot be used normally in some scenarios. In addition, some brightness cannot be adjusted, and it is difficult to ensure that the brightness is appropriate when used.
Second, what is the good thing about a good eye-protection table lamp?
1. The quality of the light source
We know that the quality of the light source of the traditional LED table lamp is not good, the spectrum is not continuous enough, there is too much blue light, and the color rendering is low.
If the product wants to be qualified, it must suppress blue light, so manufacturers have thought of a lot of ways.
The least expensive method is to filter blue light with a membrane, which is not very effective and does not improve the spectrum; A good product will switch to a better lamp bead, which will achieve a better spectrum and also reduce blue light.
There are many brands of lamp beads, and the effect is also different, not only lamp beads that use blue light excitation like traditional table lamps, but also lamp beads that are better based on violet light excitation. The better the lamp beads, the better the quality of the light source.
Nowadays, good eye-protecting table lamps basically have a full spectrum, and they also strive to keep up with the sunlight spectrum. Not only can they easily achieve RG0 level without blue light hazards, but also the color rendering is getting higher and higher, and they can basically achieve Ra and R9 greater than 90.
2. Lighting capacity
Good eye protection desk lamp lighting ability is excellent. They use a larger light-emitting surface, use more light-emitting chips, and also apply technologies such as side illumination, diffuse reflection, etc., to achieve brighter, more uniform, wider illumination, and also reduce glare and shadows.
The national standard AA illuminance standard is just the bottom line for them, and they can do better.
3. Safety
Now it meets the AA standard of eye protection table lamp, which basically overcomes the hazards of blue light and strobe.
3. What is the price of a good product at least?
In fact, as long as you choose well, a few hundred yuan of products is enough, there will be no obvious shortcomings in all aspects, those more expensive products will have more intimate functions, we can buy on demand. Products below 200 should be purchased with caution.
Fourth, how to choose good products
Note the following six points:
(1) Meet the national standard AA illumination standard;
(2) The color rendering Ra and R9 should be higher than 90 as much as possible;
(3) The color temperature is fixed not more than 4000K, or can be adjusted to below 4000K;
(4) There is a certain shading design;
(5) No blue light and strobe hazards.
Finally, I would like to recommend a few good products to you.
1. Babyview OP36
The illumination of the central area of this product is 1470lx, and the uniformity is 1.68, which is significantly better than the AA standard. It uses a full-spectrum chip with high native color rendering, Ra of 97.2, and good light shading.

2, Comic Book Rain K1
This product is based on violet excitation technology, the light source is more reductive to sunlight, and the effect of suppressing blue light is better. It also adds a red light gain function, which can improve the red light spectrum above 670nm, which has a certain effect on children's eye health. The products far exceed AA standards, Ra>98, R9>92.
3. Midea's ultra-domain light PLUS
This product has a 47cm long luminous lamp head, with a wide irradiation area and a coverage area of 1.3m*1.2m, which meets the requirements of AA illumination. It has a decent full spectrum with high color rendering, Ra of 98 and R9 of 96.
Above, I hope it will be helpful to everyone.
