First of all, there must be a reliable and safe light source. The doctor suggested that it is best to use natural light as the light source, specifically the sunlight scattered at ten o'clock in the morning, which is the most comfortable for human eyes. The following data, after pro-testing, perfectly match the sunshine index, which can be said to restore natural light to the greatest extent:
(7) Illuminance, reaching the national CQCP visual work desk lamp A standard, reaching 350~500lux, fully meeting the lighting needs of children's healthy writing. At present, it is estimated that there are no more than 9 table lamp brands certified by CQCP in China.
(8) The color temperature is 4000K.
(9) The color rendering index exceeds 97, and CREE (American listed company) LED chip is adopted.
(10) No strongpoint, 12V low-voltage DC is used, and the lighting is soft.
(1 1) adopts direct light emission and imported light guiding film diffusion technology to suppress blue light to the maximum extent. According to EU EN6247 1 Photobiological Safety Certification, the hazards of blue light and electromagnetic radiation are RG0 harmless standards, and the blue light index is lower than that in sunlight.
(12) Use a diffuser without glare.
It is worth mentioning that in addition to the first-class light source, one-person E-lamp also has a patented technology that far exceeds all eye-protection desk lamps, that is, "integrated sitting posture reminder". This redefines the "eye protection desk lamp". Even if the light source meets the standard, it will stop at the desk lamp, and the sitting posture reminding function of one-person E-lamp truly achieves the greatest degree of "eye protection". This patented technology uses ultrasonic and pyroelectric infrared sensors to detect children's sitting posture and ambient brightness. For example, when a child unconsciously bends or bows his head during study, resulting in the eyes being too close to writing or the sitting posture being deviated, one person's E light immediately sends out a voice reminder to remind the child to correct the sitting posture in time.
In addition, a very useful function is introduced. One-person electronic lamp is equipped with a player, which is a HIFI-class speaker and has no harm to children's eardrums. You can insert a USB flash drive and play English listening, children's stories, children's songs and so on. It's very convenient. You don't need to buy another listening device.
After a long time, I bought this one-person electronic eye protection desk lamp in JD.COM. Although the brand is not big, this company is indeed a professional company that makes LED table lamps, and many big brands in the market are looking for outsourcing companies to pursue the popularity of "eye protection table lamps", and many qualifications are not available. When you buy, you must look for qualified brands that have passed at least 3C certification! The quality of cheap goods is really terrible. Single electronic lamp certification includes:
China 3C Certification (No.:201601kloc-0/001862225)
China CQCP Visual Work Table Lamp Performance Certification (No.:CQC16010143444),
EU EN6247 1 Photobiological Safety Certification (No.:WPL-6247 1A-0 1A).
Patent number:
Bluetooth speaker lamp with recording function (serial number: ZL 20 14 2 0760823. X) bluetooth smart lamp with infrared remote control (serial number: ZL 20 14 2 0469807.5) smart desk lamp with sitting position adjustment detection and light automatic sensing function (serial number: ZL 20152 039929.7): ZL 20152 03388/kloc-.
Finally, under the premise of reasonable use of eyes, avoiding extreme light environment and ensuring scientific beauty, it is obviously more reliable to install several low-power lamps in each area of the same space than a high-power lamp in the middle.
