What is the appropriate brightness of the desk lamp?
With the continuous advancement of science and technology, the lamp bulbs on the market are roughly divided into five types: incandescent lamps, energy-saving lamps, fluorescent lamps, eye protection lamps, and led lamps. Due to the huge work and study pressure of people, the usage of table lamps in daily life is increasing, so how many watts of light bulbs are suitable for table lamps? If the desk lamp is used improperly, it is easy to cause damage to eyesight. Studying and working under too strong or dimmed light will have a great impact on the eyesight. The room lighting in the family is generally 40 watts or 60 watts fluorescent lamps, but the use of fluorescent lamps to study and work will have a very bad effect on eyesight. How many watt bulbs are suitable for table lamps? I believe that most people don't know much about this problem. Lighting applications also play an important role in the use of table lamps. Not only do you need to use table lamps during study and work, but you also need to turn on other lights in the room. This can effectively reduce the damage to the eyes caused by the difference in brightness and darkness in the lighting project. The fluorescent lamp emits a cold fluorescent with a gray-blue tone. The light will make the text pattern lack a sharp sense of contour, which makes the eyes prone to fatigue. The color temperature of the lamp directly determines the softness of the light to a great extent. The color temperature is best 4500K-5200K between.
The table lamp has a great influence on people's vision health during use, and to a certain extent directly determines the deepening and slowing down of vision. Children must pay attention to prevent the damage of bright light to their eyesight when using their eyes, and prevent them from studying and reading under too strong light in time. So how many watt bulbs are suitable for desk lamps? At present, most desk lamp bulbs on the market use 40-watt or 20-watt fluorescent lamps, which can effectively ensure the lighting effect of 400-700 lux. Children's desk lamps mostly use energy-saving lamps of about 30 watts or 12 watts, and the color temperature is between 4000K-4500K.

Correct use method of desk lamp:
First of all, the brightness must be appropriate: if the brightness is too low, the light on the book will be dim, and it will be difficult for us to see the writing clearly. This will cause visual fatigue, and over time will lead to myopia. If the brightness is too high, the excessively strong light will be reflected into our eyes through the white paper surface, causing glare, causing the pupils to shrink continuously, causing eye pain and headaches. Generally speaking, a soft and uniform white lamp brightness is the most suitable.
Secondly, the placement of the desk lamp also has a great impact on vision: because most people write with their right hand, the desk lamp should be placed on the left front of the body, so that the hand will not form a shadow on the paper when writing, and it will shine on the paper. The light will not reflect into our eyes and cause glare.
Finally, the height of the desk lamp is also very important: usually, when your eyes are 30 cm away from the book, you can see the handwriting clearly without being overly fatigued. Based on this calculation, the height of the desk lamp is 40-50 cm away from the written text, so as to ensure sufficient Reading lighting, the surrounding environment also has a certain brightness.
If the desk lamp is too high, the light will directly hit our eyes, causing glare; at the same time, the short-distance strong light will also cause light retention on the retina, which will tighten the eye muscles and accelerate the decline of vision.
If the desk lamp is too low, it will make the light shine in a too small area, and the surroundings will be completely dark. The loss of a reference for far-sightedness will cause the eye adjustment systems to be in a tight and compressed state of looking only close, which is easy to make the eyes tired and accumulate quickly, resulting in "light source myopia".
