Driving China, April 21, 2021 news: today, under great pressure, as adults, we bear the unbearable burden of life. Even the flowers born in the honeypot are obviously not easy. After a day of intense course study, there are endless homework waiting for children to go home at night. Excessive eye use leads to the growth of myopia, which is really not new. Of course, there are many parents in order to protect their children’s eyes, will also spend a lot of money to buy an eye lamp, but do you really buy qualified products?
According to relevant reports, in March this year, consumer report selected nine popular eye protection desk lamps for evaluation, including Panasonic , Liangliang, Midea, Philips, hashibao, Rex, haoyanjing, Foshan Lighting, OPP lighting, etc. all the products are labeled “AA level”. In this experiment, the illuminance, uniformity, color rendering index, color temperature and other indicators were tested.
The evaluation results show that the nominal trademarks of Panasonic HHL t0521, OPP lighting mt-hy03t-208 and Midea mtd12-m / k-02 eye protection lamp are not up to the standard, and the unqualified items are uniformity and color temperature.
It is understood that according to the national standard GB / T 9473-2017 performance requirements for reading and writing desk lamps, the uniformity of class A and AA desk lamps should be ≤ 3. However, according to the evaluation results, Panasonic HHL T0521, OPP lighting mt-hy03t-208 and Midea mtd12-m / k-02 eye protection desk lamps are substandard products because the uniformity of 30 ~ 50cm area does not reach the nominal “AA level”. The three kinds of eye protection desk lamps have false product standards.
In addition, according to the national standard GB / T 9473-2017 performance requirements for reading and writing desk lamps, if the upper limit of the nominal relevant color temperature range of LED lamps with adjustable color temperature exceeds 4000K, there should be a warning that the color temperature should be adjusted below 4000K at night. If the color temperature is not adjustable and the nominal relevant color temperature is higher than 4000K, there should be warning words including the following contents. This lamp is not suitable for night use.
According to the evaluation results, the maximum color temperature of the two eye protection table lamps of OPP lighting mt-hy03t-208 and Midea mtd12-m / k-02 are all above 4000K. When children read and write at night, if they continue to use lights with a color temperature of more than 4000K for a long time, it may cause damage to children’s vision. In fact, these two eye protection table lamps are not suitable for use at night.
What’s the point? Under the banner of eye protection desk lamp, it’s not eye protection. It’s just that the uniformity is not up to the standard. The key is that the eye protection desk lamps of famous brands such as Midea and OPP lighting are not suitable for use at night. As a result, it’s very embarrassing and totally betrays the trust of consumers.
