Five ways to choose eye protection table lamps, so that children's eyes will not hurt.
Choose LED light source
The closer to the natural light is the good reading light, and the eye protection lamp uses natural light as the light source. The choice of light source should be free from stroboscopic, glare, and ultraviolet rays. LED light source is identified as the artificial light source closest to natural light, with pure light, long service life, no radiation and no stroboscopic.
Nowadays, many good LED desk lamps use a special filter or diffuser, which not only reduces high-frequency blue light, but also avoids glare, so that the damage to the eyes will be less.
Choose color temperature around 4000K
When choosing an eye protection desk lamp, the color temperature is also very important. According to research, the sunlight around 10 am is the most comfortable light for human eyes, and the average color temperature is 4000~4200K. Therefore, if the comfort of the human eye is consistent with the feeling of sunlight, a color temperature of about 4000k should be selected.
The standard color temperature is around 4000k, the light is soft, and the use is comfortable and not dazzling. If the color temperature is too low, the lighting environment will be dim, you will not be able to see things clearly and you will feel sleepy. On the contrary, too high color temperature will make people highly nervous under the light, and the eyes will be very tired.
Choose a color rendering index above 80
The color rendering index is an important indicator used to measure the color rendering, and the range of this value is 1 to 100. The higher the color rendering index, the more true the color of the object can be reproduced. The color rendering is poor, and the eyes will be more tired when looking at things. It is recommended to choose a color rendering index above 80 to restore the true color. If you often paint and have high color requirements, you can choose more than 90. The color rendering of desk lamps below 80 is relatively poor, so it is recommended not to buy.
Optional adjustable brightness
Speaking of brightness, many people have different perceptions of light. The choice of the brightness of the desk lamp depends on the light and darkness of the environment and the acceptance of the eyes, not everyone can use the same brightness. At the same time, the range of brightness is also related to age, children are different from adults and the elderly.
In addition, it should be noted that the brightness of the desk lamp is not as high as possible. If the brightness is too bright, we will feel dazzling. If the brightness is too dark, it will be difficult to see things. Therefore, it is necessary to choose an LED desk lamp with adjustable brightness to meet the needs of children in different learning environments.
Use ring light head
The use of desk lamps is for reading or learning. Therefore, the illumination range of the light should be large enough to avoid the formation of blind spots and shadows. Generally speaking, the ring-shaped lampshade of the eye protection lamp can make the distributed light evenly illuminate the table, which can give the child enough lighting space. And many desk lamps are designed to adjust the rotation angle, so you can take photos wherever you want, and you can use them more freely.
The ring-shaped double light source has a larger illumination range. The ring-shaped light-emitting surface has 44 lamp beads, the irradiation area is larger, and there is no lighting dead angle. Using the principle of diffused light, the side lighting and refraction are scattered, which is close to the most comfortable natural light reading conditions. Under its light source, the book is clearer and more natural. Built-in LED blue light reduction chip, no flicker, more assured to use.
