Many parents want to choose a table lamp for their children to use for Xi, but they don't know much about it, and don't know what is the difference between table lamp A grade and AA grade?
In fact, the A-level and AA-level mentioned here are the illuminance level of the table lamp, with the point of the lamp's luminous surface vertically projected to the desktop as the center of the circle, less than 300mm of the 120 ° sector area, the A-level illumination should be greater than 300LX, and the AA-level should be greater than 500LX; in the 120-° fan-shaped ring with illuminance greater than 300mm and less than or equal to 500mm, the A-level illumination should be greater than 150LX, and the AA-level should be greater than 250LX; and the uniformity should be less than or equal to 3.
It can be seen that the table lamp with AA illumination will be better than the table lamp with A-level illumination, but it is not enough to want a table lamp that can protect the eyes, and you should pay attention to the following points:
1. Adjustability
If the light is too bright or too dark will cause eye fatigue, it is recommended to choose a table lamp with brightness adjustment ability, which can adjust the most suitable brightness in the face of different light environments and personal needs to avoid the impact of light on the eyes.
2. Anti-harmful blue light
Blue light is a kind of visible light with short wavelength and high energy, which can easily penetrate the lens and directly damage the retina, resulting in myopia and other conditions. Therefore, we should pay attention to whether the anti-blue light of the desk lamp reaches the RG0 level of no blue light hazard.
3. Color rendering ability
The color rendering ability of a table lamp refers to the ability of light to restore the true color of an object. The higher the color rendering index, the more realistic the color of the object will be, which can reduce the adverse effects of color aberration. It is recommended to choose a table lamp with a color rendering value of more than 90, which is more friendly to the eyes.
The above are some of the key points for choosing a table lamp, and then I recommend some AA level eye protection table lamps that are most suitable for students to use!
