Energy -saving cannot be at the cost of vision decline.

Now myopia is getting younger and younger, and some of the second and third grades wear a thick wine bottle bottom. On the one hand, because there are more mobile phones and play computers, there is a more important reason. The table lamp. The cheap so -called energy -saving LED, glanced at the eyes for a long time, and slowly adapted to adaptation. In fact, the eyesight of the eyes has fallen. It’s just light pollution. So how do you choose a table lamp and how much do you know?

A eye -protection table lamp, key indicators sorting: spectral continuity, color rendering index, brightness, flashing, color temperature

Why the flashing is behind, because a good table lamp can ignore the flashing problem at all!

Color temperature is not an essential indicator for eye protection, not to say that the yellow light of low color temperature looks eye protection, but if the yellow light with poor light sources in the table lamp itself hurts the eyes. For example, the current 3000K color temperature ordinary energy -saving lamp is used for table lamps. On the contrary, the key reason is that the color rendering index is poor. Like high-level fluorescent platform lights, it is generally between 4000K-5000K and it is also very comfortable.

The following classification will list their respective advantages and disadvantages:

节能并不能以视力下降作为代价,最适合眼睛的台灯应该怎么选

(1) Hot hair light

Advantages:

The showers are all 99. The color closest to the sun. The spectrum is the most comfortable as the sunlight. The color temperature is about 2500k-3000K. The yellow light lamp is the most comfortable in the incandescent lamp halogen lamp, because the show is high, soft and comfortable. The hot light is flickering, which is the same as the rhythm of AC power, but there is a cooling effect of hot hair light, so the human eye basically does not feel the flashing. This does not need to consider.

Say disadvantages:

The heat is large and the light efficiency is not high. In summer, the head always feels the heat. The brightness of the brightness of about 40W is about 40W. Energy consumption (40W is actually drizzle than air conditioners). The color temperature is not high, and the high color temperature is at least 100W. This heat is not controlled by civilian use.

Speaking:

Because the light effect is too low, it is not recommended. You have to read at least 60W incandescent lamps, and the color temperature is low. Recommended halogen lamps, Osram’s 33W starts, 33W of Osrand Berlin platform lamps, 40W of ordinary G9 halogen, E27 snail mouth ordinary Foshan lighting 43W. Osram 46W Several options.

Sense of light

: This kind of platform is most suitable for reading in desk, reading and writing, and not tired of eyes for a long time. You can also be used as a computer environment platform. The disadvantage is that the brightness is not enough.

(2) The fluorescent platform lights:

The three-base color fluorescence tubes stimulated by ultraviolet rays are very easy to reach 6,000k, but the color temperature value suitable for reading is generally 4000K-5000K, which is too high to be blue. The brightness is easy to achieve. Lighting, the color rendering index is about 85 % or more, and there is no blue light problem with the spectrals (why the blue light problem is not mentioned earlier because the hot light does not exist in this problem).

Flashing problem, now the manufacturer can mainly solve the high frequency rectifier, that is, to increase the frequency to about 5,000 high -frequency flashing, making people feel unable to feel (many web texts say that the pupils of the human eyes will shrink with flashing, which is purely purely a purely belonging to the eyes, which is purely purely a purely belonging to the eyes. Dog blood guess, if people’s eyes have long been hung up), in addition, fluorescent powder has an after more effect, which can also reduce the flashing feeling. Generally speaking The flashing feeling obviously felt.

UV radiation, because this inspiration is used, but ordinary glass generally isolate 90 % of ultraviolet rays, which can be understood that there is not much problem. The electromagnetic radiation problem brought by the high -frequency rectifier will exceed the safety value of the low -frequency low -frequency electromagnetic radiation exceeding 0.20UT. After leaving the human body 30cm, it is basically within 0.20UT safety value. I used the low -frequency instrument. Environmental protection issues, mercury pollution after abandoned.

It is recommended to choose a high -level fluorescent lamp tube. Do not choose the energy -saving lamp, because the energy -saving lamp is a shrinking version of the fluorescent lamp. The rectifier elements are far less than the fluorescent lamp type. The boss of the fluorescent lamp is Panasonic, and Panasonic’s fluorescent platform lamp is definitely the best lamp. In fact, the SQC957 is the top professional drawing light, which can reach 950 lumens. Secondly, 3M fluorescent platform lights. A optical filter film, the filter is softer, the top lamp of 3M is TL-1000. Domestic recommendations are the best fluorescence lamps, the best domestic fluorescent lamp, and MT001Y is cheap.

In summary, the fluorescent platform lights are the most widely used. Because of the brilliant, high color temperature, reading work is adapted, and long -term fatigue strategy is a bit more comfortable as halogen lamps, but this is the best choice class in the current folding, light, light, light, light, light, light, light, light, light, light, light, light, light, light, light, light. It is worse than the LED light, the following is a detailed description.

(3) LED table lamps

In terms of eye protection, the LED lights are actually not except for energy saving. Non -PWM lights are not flickering. I can’t think of how much advantages. In fact, these are not important at all. Flashing is just a concept that LED lamps are used for hype. Those so -called flashing senses are estimated to be taken only by camera mobile cameras. It is very difficult for human eyes to distinguish the flashing of high -grade fluorescent lamps.

Ordinary LED lamps are blue lights that are mixed with yellow powder in blue light. This spectrum has obvious problems. In the three -color light, there are significantly blue light, and there are fewer red and green spectra. The continuity is poor. Only the top RGB three-color LED can reach the level of the three-based fluorescent lamp spectrum, but the cost is relatively high, the heat is large, and the civil table lamp basically does not have RGB-LED. The color rendering is also relatively poor. Generally, the display of LED lights is less than 75 %, and the explicitness of the high -grade LED lamp beads can reach more than 90 %, but the cost is very high, and the civil table lamp is rarely used.

Advanced LEDs mainly filter the light and other lights such as blue light through the filter board, and increase the comfort. Individuals generally do not recommend LED table lamps. Please choose Panasonic, 3M, Philips, Osram and other large brands such as LED table lamps above 80 Essence I personally think that in addition to the RGB-LED table lamp, ordinary LED lights are only suitable for flashlights, making small night lamps, not suitable for reading.

I stayed under this light for a long time, dizzy and uncomfortable. In short, I used the halogen lamp and Panasonic fluorescent platform lights. I was not used to the LED light.

Now the mainstream eye protection lights are LED lights, such as Philips, Panasonic, Op, Xiao Erlang, Dr. Edward, etc. Compared with ordinary LEDs, they have stricter control of color and warm phase spectra. When choosing, cautious, comprehensive and practical, which kind of watching you want, and recommended
