But also said that due to no ultraviolet and infrared spectrum, so there's no heat, no radiation, will not bring burden to the human eye, long time reading or working there will be no eyes ache bloated phenomenon (
This is the use of LED lighting'

That is led lighting, lighting is a solid light-emitting semiconductor devices.

, don't look at the LED?

actually should say so, all the artificial light'
The object giving out light itself can call light source, light source can be divided into natural light and man-made light.

Such as improper use will certainly affect vision, specific to the LED lights, is responsible for factory production of products, in the artificial light safety'
Safety value as a kind of objective existence, in theory should be measurable, and measure the concept of security can be referred to as the degree of safety.

A batch of relative is the highest, is not responsible for factory production sold by weight or TB 2 piece of wallet mail, to the degree of safety is the lowest in the artificial light.
I said look at everyone's in blue light damage, blue light damage is there must be first, there are a lot of factory laboratory instrument light need aging test, of which most blue 450 nm, before my wife doesn't myopia, eyesight is very good, but occasionally into the lab to see the aging situation, 2 years time, eyes began to rise the pain and see the wind tears.
As for the other friends, customers to buy some high colour temperature bargains, home after install, the worst I've ever seen a 3 mouth can't turn on the light at night, because as long as a turn on the light, all dizzy eyes ache.
Later I help him changed RA95 warm white LED lamp, the problem was done not have.
Blue light damage vary from person to person, for some people who are sensitive, high color temperature blue paint with glare, serious immediately, and for some people may only be a little inappropriate, accustomed to spend paragraph of time also is not much feeling.
But the damage is certainly exist.
of all the artificial light, according to index of more than 80 LED, warm white belongs to one of the lowest proportion of blue light, are white blue belongs to a middle-class, that is to say, if according to index above 80, LED blue light damage will not higher than energy-saving lamps.
Was in accordance with the standard LED lights display index is more than in 80, but now many of the LED lights are around 70, 60 more extreme, there is.
in the end is not responsible for, and now all leds measure, the vast majority of people throughout the only standard is enough bright &;
。
Taobao see light source products, many of them are baby good reviews, very bright.
Now that you have all the brightness as the only standard, manufacturer is happy, of course, because the same chip, do show index 70 lights, brightness of at least 10% higher than show that index 80, lower cost and low index, such as 2835 lamp bead, you are not required to display index, 3, 4 cents a 60, 26, 7 lumens brightness.
Requirements according to index, more than 80, should be in basic 7 8 points a, 24, 5 lumens brightness.
If do according to index of more than 90, mostly to in 1 5 MAO even higher, 21, 2 lumens brightness.
So show index is higher, the cost of the more expensive and it is doubled, brightness is declining, the last is really good, the price is expensive, brightness haven't others the same power of a bargain.
Sell motionless, manufacturers are not willing to do, anyway, we all see the brightness, then do good throughout & high brightness;
