I have been using the desk lamp for many years, and I just replaced the five-year-old desk lamp, compared with the ordinary table lamp, the use experience of the eye-protecting table lamp definitely makes learning a kind of enjoyment! In order to reduce the precious time of friends, I collected five popular eye-protection lamps on the market, as well as netizens' questions about eye-protection lamps.
1. Does the eye-protecting table lamp have an eye-protecting effect?
In fact, the high-quality light environment can protect our eyes to a certain extent, and the eye protection desk lamp can provide suitable light, so it is useful, the principle of the eye protection table lamp is to use frequency conversion electronic ballast, the low frequency flicker is promoted to high frequency flash, when the number of flashes per second of the light increases to a certain extent, the frequency is controlled at 50kHz, reducing the damage of light strobe to the eyes, so that the naked eye can not detect, so as to reduce the fatigue of vision; The eye-protecting desk lamp also uses tri-color phosphors to soften the brightness of the light and make the light close to natural light, so the eye-protecting table lamp plays a role in protecting eyesight to a certain extent.
2. What is the purchase guide for eye protection table lamps?
The eye-protecting table lamp is not a blind selection, but a selection that suits you, so how to choose? In fact, there are only a few points to choose the parameters, and you can choose according to your own needs
1. Illumination and uniformity
Illuminance refers to the amount of light per unit area when the light hits the surface of the object, generally speaking, it is the brightness of the irradiated surface, the illumination is too low, the light is dark, not only will cause eye fatigue, but also easy to cause myopia; The illumination is too high, the pupils continue to shrink and expand, which will also lead to eye fatigue, and may also cause headaches, the most recommended is 500 750lux (lux), and the country has a clear division of illumination There are national AA and national AA level, and it is best to directly choose the national AA level.
Uniformity refers to the ratio of the vertical center illumination of the lamp to the illumination of the edge, the closer this value is to 1, the better, the national AA standard uniformity is within 3, but this range is wide, and now the uniformity of the eye-protecting desk lamp is about 2, which can achieve uniform distribution of light.
2. Color temperature
Color temperature is the scale of the light color of the light source, popularly speaking, it is usually warm light, cold light, cold color light with high color temperature will stimulate the eyes, warm color light with low color temperature because of insufficient light makes the eyes easy to sleepy, the healthiest color temperature should be the color temperature closest to natural light, for example: the light color temperature of a candle is about 2000K, the color temperature of an incandescent lamp is 2500-3000K, and the color temperature of sunlight at ten o'clock in the morning is 4000K, so the color temperature at 4000K is the most suitable for learning and reading.
3. Color rendering
Color rendering refers to the degree of color presentation of the light source to the object, that is, the degree of verisimilitude of the color, the light source with high color rendering has a better ability to present the color, and the color rendering also has an index, the full score is RA100, we need to choose the table lamp with a color rendering index of RA90 or above, if the child uses the table lamp for learning or the color rendering index of the person used for painting is relatively low, it will cause color distortion, resulting in visual fatigue, the closer the color rendering is to the value of 100, the better the color rendering effect of the light source.
4. Blu-ray
Blue light refers to a kind of visible light in the blue light source, first of all, blue light is not all harmful, the really harmful blue light 400-440 nanometers, it will increase the amount of toxins in the macula area of the eye, seriously threatening our fundus health, and 480-500 nanometers between blue light is a role in adjusting biological rhythms, and sleep, mood, memory, etc., are related to the human body, the international lighting will be retinal blue light danger divided into four levels, no danger class (rg0), Low hazard class (RG1), medium hazard class (RG2) and high hazard class (RG3), non-hazard class RG0 is the highest level of safety and can protect our eyes to the greatest extent.
