Mainly know some knowledge of student supplies, you can have a deeper understanding The difference between the two is that it is best for students to use an eye-protection lamp when studying, so that they can protect their eyesight well.
When an ordinary desk lamp is working normally under a 50 Hz alternating current state, it will flicker about 100 times per second. Such a high flicker frequency is invisible to the human eye. Therefore, a long time under the desk lamp, coupled with the careless eye hygiene, is extremely prone to myopia. The principle of most eye protection lamps is to increase the electrical frequency of 50 Hz to 40,000 to 55,000 Hz, and the flicker frequency of the corresponding table lamp per second will be greatly reduced, and some can even be reduced to zero. The function of protecting eyesight.
Features of eye protection lamp
(1) White light similar to natural light, stable brightness, no flicker, and will not cause eye fatigue.
(2) The light-emitting area is large, and it is not easy to produce glare and large-area shadows harmful to eyesight.
(3) Instantaneous bright spot, quiet and no noise after lighting.
(4) Compared with ordinary incandescent lamps, it can save 80% of electricity, and the average lamp life can reach more than 6000 hours.

There are many brands of eye protection lamps on the market, and the price difference is also large. When choosing an eye protection lamp, pay attention to its practical functions. In general, you can choose 15W-18W energy-saving lamps, high-frequency lamps with higher frequency, and electronic circuits that eliminate electromagnetic radiation. Don't be affected by products that unilaterally promote brightness. Misleading.
