Recently, I found that when my child was reading at night, he squinted his eyes, and after investigation, I found that it was the lighting problem of the old desk lamp, which caused the child's eyesight to deteriorate, so I urgently needed to buy a new desk lamp to save the child's eyesight. Overview of the table lamp market, to meet the requirements of a lot of really a lot, but considering the brand, quality and after-sales and other factors, it is difficult for everyone to choose, and finally I spent a month to evaluate the current popular eye protection table lamp, and finally sorted out into a strategy to share with you.
Key points for the purchase of eye-protecting table lamps
Point 1
Blue light of table lamp]: Blue light is actually a part of visible light, which has the characteristics of short wavelength and high energy. Blue light with a wavelength of 380-450nm is harmful blue light, which will cause certain damage to retinal photoreceptor cells and nerve cells, and will cause myopia and so on after long-term use.
According to the degree of injury, it is classified as exempt RC0), low risk (RG1), intermediate risk (RG2) and high risk (RG3). Choose a table lamp with an anti-blue light level of RG0 without blue light hazards to protect your eyesight.
Point 2
Illuminance of table lamp]: Illuminance usually refers to the luminous flux received per unit area, and the unit is generally expressed in lux.
The light intensity refers to the fact that the center of the light source has a standard brightness value within a specified range, and it cannot be less. According to the national standard GB T 9473-2017 "Performance Requirements for Reading and Writing Desk Lamps".
The illumination of the eye-protecting table lamp needs to meet at least the national A-level standard, and the best national Aa-level.
Class A illumination: the illumination of the ** area is required to reach at least 300lx, and the edge reaches 150lx;
Class AA illuminance: At least 500lx is required in the ** area and 250lx at the edge.
Therefore, it is better to give preference to AA illumination. Uniformity, on the other hand, requires both A-level and Aa-level illumination, and the value is closer to 1, the better.
Point 3
Stroboscopic of table lamp]: Strobe is actually a phenomenon that exists in many lamps and lanterns, display screens, etc., and the longer the use time, the more obvious this phenomenon will be. Refers to the light emitted by a light source that changes rapidly and repeatedly over time, making the light source bouncing and unstable. If the strobe is not up to standard, long-term use can lead to visual fatigue, migraines, vision loss, and so on.
The national strobe requirement for qualified light source products is 3125Hz, so we pay attention to whether the anti-strobe of the table lamp meets the standard of "no flicker" when selecting.
Point 4
Color rendering of the table lamp]: Color rendering refers to the color effect of the object under the illumination of the light, and the higher the color rendering index, the better the restoration effect of the table lamp on the color of the object, and the more realistic the color of the object.
Table lamps with high color rendering value are not only beneficial to children's perception of color, but also reduce the impact of color difference on vision.
The standard color rendering index (RA) value of the eye-friendly table lamp needs to be above 80, usually we only need to choose more than 90.
Point 5
Color temperature of table lamp]: Color temperature is a physical quantity unit used to define the color of the light source in illumination optics, which is generally expressed in Kelvin (k).
The visual impact of different color temperature values will be different, the lower the color temperature value, the more "warm" the light color, although it can make people feel warm, but it is easy to make people tired and sleepy after a long time. The higher the color temperature value, the "colder" the light color, although it can make people concentrate, but it is easy to cause eye fatigue after using it for a long time.
Therefore, generally we try not to choose too high or too low color temperature value when choosing, the best color temperature value is 4000k warm white light, the light will be closer to natural light, and it is relatively mild and comfortable, not easy to cause eye fatigue.
Point 6
Lighting range of table lamp]: When we choose table lamp, we must pay attention to choosing a wide enough lighting range, if the lighting range is too small, there is a more obvious difference in light and shade in the process of use, and it is easier to form shadows, and long-term use will aggravate eye fatigue.
Therefore, it is recommended to choose a table lamp with a large luminous surface and a wide lighting range when choosing, the light will be more sufficient and uniform, and it can better protect eyesight.
An eye-protecting table lamp suitable for children
(1) Scholar eye protection desk lamp L1 Pro
Word-of-mouth rating:
Recommended reason: The current industry benchmark products achieve eye protection and are more eye-catching, subverting the traditional concept of eye protection table lamp
As a professional optical eye care brand in China, Suker Shuke exceeds the national standard AA level by 110% in terms of basic optical performance. It has not only passed the certification inspection of the European Union, Japan, the United States and other countries, but also pioneered the brand of red light gain, and introduced RRT red light eye care technology to achieve a more eye-catching eye protection effect. This revolutionary technology provides users with a new eye-care experience and at the same time brings innovation to the field of eye-care table lamps.
Suker's RRT red light eye-catching technology and the design of 168 Sunbeam-like solar lamp beads greatly weaken the blue light peak, supplement the beneficial red light, and deliver "nutrients" to the eyes, including protecting retinal pigments, improving the activity of epithelial cells, and promoting blood circulation. Helps reduce the risk of myopia by 92% and alleviate eye fatigue by 83%.
In order to improve the user's sense of security, Suker Shuke has adopted a medical-grade product line, and has carried out four major quality tests on each batch of table lamps. This practice is designed to ensure the quality and safety of the product and provide users with a more reliable eye-friendly table lamp. Medical-grade product lines often require higher manufacturing standards to ensure that the product will not adversely affect the user's health during use. Quality inspections help identify and address potential safety issues, ensuring that each batch meets high quality standards.
In order to provide comfortable lighting and use, the ghost-free backlight technology is used to eliminate shadows and reduce dark areas, ensuring uniform illumination. In addition, the table lamp is also equipped with functions such as automatic light on/off and regular breaks, which makes it more convenient for users to use it. Especially for parents, these features also allow children to use the lamp independently without a parent nearby.
