Which is better, led desk lamp or eye protection lamp?
Why are there so few lamps in our daily life and learning? There are many people who use LED desk lamps and eye protection lamps, but I don't know which is better. The following eye protection lamp manufacturers will help you. For comparison, please read carefully.
Which is better, led desk lamp or eye protection lamp? Let's introduce them separately;
The led desk lamp has good directionality and can be illuminated on demand. It is suitable as an emergency desk lamp. The led desk lamp adopts DC power supply, no stroboscopic, no electromagnetic radiation, green environmental protection, high efficiency and energy saving. In addition, the LED lamp beads have a longer lifespan. In addition, the longer the LED desk lamp is lit, the faster the phosphor in the light source decays, and as a result, the light in the blue light band that the human eye contacts will become stronger and stronger, thereby causing damage to the human eye. Therefore, when the eyes look at the LED light source for a long time, it is easy to make people feel dizzy and uncomfortable, and even cause eye damage, which will increase the probability of eye disease. Reminder, do not let your eyes stare at the bright LED light source for a long time to avoid eye damage.
Let's talk about the eye protection lamp. The eye protection lamp uses a variable frequency electronic ballast to increase the electrical frequency from 50Hz to 30-50kHz, and the change in the brightness of the light becomes very small due to the afterglow effect of the phosphor, so the human eye There is basically no stroboscopic feeling, and the light uses tri-color phosphors to make the light soft, so as to reduce visual fatigue. The eye protection lamp first converts alternating current into direct current, and uses direct current to light the lamp, which also achieves basically no stroboscopic, which can avoid visual fatigue and has no electromagnetic interference.
The above is a detailed summary of the LED table lamp and the eye protection lamp made by the eye protection lamp manufacturer. As for which one is better, everyone has the answer. However, the editor recommends that you use eye protection lamps for the reasons mentioned above. Now students are under a lot of pressure to study. Parents can only help their children buy an eye protection lamp. If you want to know how to choose a student eye protection lamp, the editor will give you a detailed introduction in the next lecture on student supplies. Please pay attention.
