What kind of light bulb is used for student desk lamps?

Nowadays, students need to spend an hour or two doing homework every day. At this time, you need a desk lamp as a help, but what kind of light bulb is used for the student desk lamp? The main reason here is to hope to achieve the effect of eye protection. For this reason, I recommend several light bulbs that are often used by student desk lamps for everyone to choose.

What kind of light bulb is used for student desk lamps:

1, student eye protection table lamp - color temperature selection

The color temperature of the student's special eye protection table lamp is simply the light color emitted by the lamp. It is most suitable for the 5000K color temperature used in reading and writing environments. The common color temperature in daily life is 6400K and 2700K, and the color temperature of 6400K is suitable for general public. The use of places, such as subway stations, public toilets, etc., the color of the light is slightly white and slightly blue, it is necessary to note that the color temperature of 6400K and 2700K is not suitable for reading and writing environment.

2, student eye protection table lamp - brightness

The light height refers to the distance between the lamp and the table. The distance specified by the state is greater than 40 cm. However, many people don't know much about this decision. I don't know why this standard is needed. This is because the student special eye lamp. Below 40 cm, the eye's line of sight is above the luminaire. Seeing a bright area and a dark area, the brightness changes are relatively large. Such a bright and light alternate lighting environment has a great impact on vision. Xiao Bian reminds everyone that Be sure to pay attention to the brightness when choosing.

3, student eye protection table lamp - principle

Under the AC state of 50 Hz, the ordinary table lamp will flash about 100 times per second. Such a high flicker frequency has a great influence on human vision, causing eye fatigue and reducing vision. The vast majority of student-specific eye protection lamps on the market work by raising the low-frequency flash to high-frequency flash, increasing the electrical frequency from 50Hz to 5500Hz to reduce stroboscopic light, reducing the glare effect and making the light more flexible. This will reduce the visual fatigue.

It is very important to remember the eyes by choosing which light bulbs are used by the student desk lamp. It is very important to remember that the eyes are not regretted.
