1. The principle of most eye protection lamps is to increase the electric frequency of 50 Hz to 40,000 to 55,000 Hz, and the flashing frequency of the corresponding desk lamp will decrease greatly every second, and some can even drop to zero. To the function of protecting vision. The principle of a small part of the eye-protection lamp is to convert the alternating current into direct current, and use the direct current to light, and there is no stroboscopic or radiation. However, the technology content is higher and the cost is higher, so the price is relatively higher. For the time being, it is not close to ordinary users.
2, most of the eye protection lamp works: the low frequency flash is raised to high frequency flash, this eye protection lamp uses frequency conversion electronic ballast, the electric frequency is increased from 50Hz to 5500Hz to reduce stroboscopic, using three primary color phosphor , reducing the glare effect, making the light soft and not glaring, so that the human eye can not feel the stroboscopic discomfort, in order to reduce visual fatigue.

3. Although the light emitted by the fluorescent lamp is white, since it is directly illuminated by the alternating current of 50 Hz, the brightness will change continuously at a frequency of 100 times per second, which is the stroboscopic phenomenon. When the ordinary desk lamp works normally under the AC state of 50 Hz, it will flash about 100 times per second. Such a high blinking frequency cannot be seen by the human eye. Therefore, under the desk lamp for a long time, coupled with the lack of attention to eye hygiene, it is extremely prone to myopia.
Second, the student special eye protection table lamp precautions
1, color temperature selection
The color temperature of the student-specific eye protection table lamp is simply the light color emitted by the lamp tube. 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 light color is slightly white and slightly blue. It should be noted that the color temperature of 6400K and 2700K is not suitable for reading and writing environment.

2, nature
As the current myopia rate of students continues to rise, the protection of vision has become a topic of increasing concern to most parents. In the use of student-specific eye protection desk lamps, it is not the price issue, but its eye protection function. It is common to divide the student-specific eye-protection table lamp into high-frequency flash and no-strobe flash. The eyes are developed and grown under natural light. The reading light source for people is natural light around 10 am, and the special eye-protecting table lamp for students. The working principle is to raise the low frequency flash to high frequency flash.
