What is the working principle of mini eye protection desk lamp?
1, the working principle of most eye protection lamps:
Low frequency flash is improved to high frequency flash. This kind of eye protection lamp adopts frequency conversion electronic ballast, and the electrical frequency is increased from 50Hz to 5500Hz, reducing stroboscopic effect. The tricolor phosphor is used to reduce the glare effect, so that the light is soft and not harsh, so that the human eye will not feel stroboscopic discomfort, thus reducing visual fatigue. Stroboscopic effect is a test index of all fluorescent tubes: the less stroboscopic, the better the lighting effect.
2. There are very few working principles of eye protection lamps:
When alternating current turns into direct current, lighting with direct current will not flash at all, thus realizing true stroboscopic. Moreover, when in use, the light is close to natural light, which is bright, but not dazzling at all, which is gentle and greatly relieves visual fatigue. Moreover, compared with other kinds of eye protection lamps, electromagnetic radiation has no radiation. The related technology of DC eye protection lamp has passed the patent certification granted by China National Intellectual Property Administration, and of course the price should not be low.
How about LED eye protection desk lamp?
LED eye protection desk lamps are generally used in office or study lighting places such as reading, writing, design and marking. For people who do desktop learning, ensuring a good visual environment in the work area is of great benefit to improving the quality of study and office work, improving work efficiency and protecting health. Only by fully understanding the characteristics of lighting and choosing suitable lamps can we make our study and work more relaxed and comfortable, be healthier, live more colorful and work more enjoyable.
Where LED desk lamps are used, if the illumination and color rendering of the lights are not enough, readers will overuse their eyesight, which will lead to eye fatigue, and long-term stroboscopic or glare of the lights will bring serious damage to people's visual nervous system, so we should pay special attention to the quality of lighting. From the point of view of satisfying the comfort and health of human body lighting and considering energy saving, LED eye protection desk lamp should meet several conditions:
1, desktop lighting should have enough illumination.
At present, the lighting design standards commonly used in schools, office buildings and other lighting places in China were formulated in the 1980s, among which the desk illumination standard for office and study is only 1/2, the international standard is 300-500 lux, and the Chinese standard is about 150 lux. Too low or too high illumination will cause reading difficulties, easily lead to reading fatigue, and affect reading and work efficiency.
2, the light should be stable
If the light is bright enough, but it keeps flashing and the light is not stable enough, we say it has "stroboscopic". When the stroboscopic frequency exceeds a certain range, visual fatigue will occur. Long-term visual fatigue will damage people's visual system. Especially in today's increasingly popular computer, many people use computers under the light. Usually, the stroboscopic flash of fluorescent lamp with inductive ballast and the frame flash of fluorescent screen overlap (50- 100 times per second), which leads to light vibration and is more harmful to human visual system. Reading or working in this light environment for a long time will cause damage to the eyes, and there will be discomfort symptoms such as eye edema and headache, and usually no reason can be found.
Today, Bian Xiao has introduced so many mini eye protection lamps. I believe everyone has a certain understanding of the mini eye protection desk lamp. When choosing a mini eye protection desk lamp, you might as well consider these methods introduced by Bian Xiao. Many people will choose to use desk lamps. First, it won't be so easy for others. Second, it can create an atmosphere. In fact, the mini eye protection desk lamp is very good for our eyesight. I hope my introduction will be helpful to readers.
