Led lights are so bad。
I've introduced led lights in several previous articles, but almost every time i say it, someone says it! The led light is not as friendly to the eyes as the led light and the incandescent light, and i am right to say that -
'cause a lot of led lights, they really hurt。
But it turns out that not all led lamps are the same. As long as they are purchased with vigilance, they will not buy the six types of lamps below. Led lamps are even more eye-friendly than energy-efficient lamps and incandescent lamps。
. 01 do not buy full spectrum
The more sensitive the eyes are, the more they feel: looking under the light, the less light they feel
Not to mention the usual lights that we have installed in our house, but it's still not clear, even if it's a big-power camera in the studio. This, actually, has something to do with the light spectral. The visible light of the sun is part of the spectrum
And energy-efficient lights, led lights, the spectrum
Distinction is found: even though it's all white light, the light from the lamps is white light from simple combinations of colours, not complete spectroscopy like solar light. That leads to..
• it's blurry to see things under the light。
If you can't see it, you need to see it hard. So when you buy a led light, remember the word "all spectroscopy." it's like this
Don't buy short-wave blue light
Let's go over the spectrum of regular led lamps
The part above that draws the red circle is the "short wave blue light" that spreads through the led light. Glasses, cellular membranes, etc., promote their "blue-proof" function against "short-wave blue-light" that harms the eyes and only short-wave blue-lights, not all of them。
Short-wave blue light, caused by led structures. I couldn't handle it, but it wasn't
As shown above, this is the spectrum of short-wave blue light led lamps. As an ordinary person, we may not see the spectrum when we buy the light, but we can see its certification:
The rg0 exemption level certification proves that the lamp is free of short-wave blue light hazards。
We got video flashes at . 03
The lights in the room, they're on, they're okay. But if you turn it off for a while, it's painful. The flash, the fast switch..
Because of the speed of the flash, the naked eye may not see it, but it can be felt。
There's one way to help you see the flash:
• take a piece of paper (or other flat things) close to the lamps (10-20 cm). Open the camera on the phone and use it to film this paper so you can see the image below
Flash, it's got to do with led's starter. To eliminate flashes, you have to select a starter of excessive mass. In addition, the “no video flash” certification for lamps can be viewed。
. 04 mask too fancy
The mask of the light can be carved and drilled, but not too much! The blizzard mask inevitably affects the transmission of light and results in light spots. The light spots, they'll be blind
The light covers are as important as the light。
In addition to being simple, attention should be paid to the material of the lamps. At present, seven main types of materials are common on the market and are ranked according to their capacity:
Pmma5 scattered glass
. 05 brightness/finger/colour temperature too low to buy
Three basic parameters for lamps are brightness, high-fingerprinting and colour temperature。
The brightness should be sufficient and it is recommended that not less than 100 lm per square metre. The power for led lamps is not less than 3 w per square metre. In particular, mobile phones are now viewed more frequently, their screens are brighter, and if the environment does not keep up, the eyes are vulnerable to fatigue。
Color index, not less than 95, and the higher the better (sunlight is 100). The obvious determines whether colour is visible, and the mall will deliberately lower it so that you don't have to pretend because you're too hard to choose。
The color temperature should also indicate, in particular, the lower the light. The twilight light makes people sleepy, so it is best to have about 5000k in rooms such as living rooms and study rooms, and the bedroom is not suggesting that it is too low, and it is best to choose a colory light。
. 06 is not a level 1 energy efficiency
We're all interested in energy efficiency. However, the efficiency of lamps has been neglected by many, but the level of their efficiency is also very important。
The first-level energy efficiency lamps are not only more power-efficient:
Level 1 energy efficiency certificates can only be obtained after 3,000 hours of constant power, constant continuous switch testing power, optical colour index, colour temperature stabilization test。
So “first-level energy efficiency” is equivalent to endorsement of the quality of the lamps。
