Table lamp is a kind of household appliance used for lighting in people's lives. The bulbs used in general desk lamps are incandescent lamps and energy-saving bulbs. The desk lamp is not only for reading and decoration. The latest technology is like a robot, which can move, dance, automatically adjust the light, play music, clock, video, touch and other functions, especially the ceramic desk lamp has the value of collection.

Because of the diversity of table lamps, the size, style and material of the table lamps are slightly different for different places of use. For example, the table lamp used in hotels is much larger than the table lamp used for home decoration, especially the table lamp used in hotel lobby, which is larger, heavier and more luxurious.

1, the degree of light bulb should be appropriate. If the degree is too low and the light on the book is dim, it will be difficult for us to read the handwriting clearly, which will cause visual fatigue and myopia after a long time. At that time, treating myopia will become a must every day.

2. The height of the desk lamp is also very important. Usually, when the eyes are 30 cm away from the book, you can see the handwriting clearly and you won't be too tired. Based on this calculation, the height of the desk lamp is 40-50 cm away from the writing, which not only ensures sufficient reading illumination, but also has a certain brightness in the surrounding environment.

3. Use a white light bulb. Scientific research has confirmed that our eyesight is the best under white light, so we choose incandescent or frosted lamps that can emit soft and uniform white light instead of colored bulbs.
