Precautions:
In the choice of desk lamp, it is also very important, that is, the lampshade of desk lamp. Don't underestimate the lampshade of a desk lamp. If the shading degree is not high, children will study for a little longer under the irradiation of desk lamps, and the intensity of light will directly lead to serious fatigue of children's strength. Over time, it will seriously affect children's vision.
Therefore, when choosing a desk lamp for your child, please pay attention to the shading degree of the lampshade to prevent the direct light source from damaging your child's vision.
Children should keep a certain humidity indoors, so many parents will use humidifiers on their children's study desks, so that children will not cause a series of breathing problems because the air is too dry during study.
Never put the humidifier near the desk lamp, keep a certain distance, or even tell children not to put the humidifier and the desk lamp together, which will not only affect the service life of the desk lamp, but also lead to dangerous leakage of the desk lamp.
