LED lamps are very popular. And it's understandable, they have many advantages. But there are several important disadvantages, which are not customary to talk about. One of them is harm to health. Let's talk about this in more detail.
First about the pros of LED lamps:
Economy. LED bulbs save energy. Using them is about 10 times more profitable than conventional incandescent bulbs. And with our ever-increasing light prices, the desire to save money is paramount. Manufacturers of LED lamps assure that their lamps can last about 30 thousand hours, which cannot be said about incandescent bulbs. They last only 1 thousand hours. Design Safety. LED bulbs have plastic diffusers, not glass.
Now comes to the important thing - the disadvantages
The main disadvantage that many people do not even realize is the harm to health. LED lights have a negative impact on people's vision.
The main reason is the manufacturers' failure to comply with production technology. Because of this LED lamps have violations:
-increased pulsation.
-incomplete frequency converter.
Some lamps have a bridge rectifier with a pulsation of 100 Hz. This frequency is very bad for the eyes, so the vision begins to sit down. In addition, such a frequency affects the psycho-emotional health of people.
The negative impact of LED lamps on health can be reduced by choosing lamps correctly.
What to look for when choosing LED bulbs
1. Color temperature. It is worth buying lamps with light that is close to natural. The coefficient should be in the range of 2600-3400K. This figure reflects the intensity of LED - blue spectrum radiation.
Sight very quickly begins to fall if a person spends a lot of time in the room with an increased coefficient of blue light.
In children's rooms LED lighting should be avoided. Children's retina is very sensitive. We need to take care of it. So give preference to halogen or incandescent lamps.
2. Flicker frequency. This indicator should NOT be in the range of 7-350 Hz. Otherwise, such lighting will have a negative effect on the nervous system.
According to the norms for living spaces, the lamp ripple factor is considered safe - up to 12%. It is worth adhering to it.
As a rule, indicators that meet the standards, and safe for health, there are only good expensive LED lamps. When buying pay attention to the above coefficients. And buy the lamps from trusted stores.
