The effect of LED lamps on human health

 

The effect of LED lamps on human healthThe whole civilized world is gradually, but with more and more decisive, switching to LED lighting, and this is not at all surprising, since LEDs open a new era in the technology of light production itself, so this highly effective technology claims to be the main one of its kind in 21 century. But how will the use of LEDs affect human health? We will try to figure it out now.

Let's start with the environmental aspect associated with the content or absence of heavy metals in LED lamps. Were very popular recently energy saving fluorescent lampscontaining mercury vapor in the flask, and this is a fact that causes unreasonable fears. In the event of a malfunction, the disposal of such lamps should be carried out in a special way, they cannot simply be taken and thrown into the bin, and, as a result, in many countries the distribution of these lamps is on the verge of being prohibited.

LED lamp

LED lamps, in turn, are devoid of this drawback. Moreover, in their design there is no more heavy metals than in electronic wrist watches or a cell phone. Therefore, LED lamps, unlike fluorescent lamps, are safe for both humans and the environment, they do not contain potentially hazardous substances.

LED lightening

Now about the light itself. LED lamps are characterized by the complete absence of ultraviolet radiation in their spectrum over the entire range of color temperatures used for lighting - from 3000K to 6500K.

This means that even when using powerful LED light sources, you can not be afraid of harmful ultraviolet exposure to the eyes or skin. It is worth remembering that not only the sun emits ultraviolet in its spectrum, but also incandescent lamps have it.

In addition, ordinary incandescent and fluorescent lamps flicker with a frequency of 100 Hz, which causes fatigue, harms vision, as well as the nervous system of a person as a whole.

High-quality LED flicker lamps do not have this, they have a built-in special electronic driver that makes the light of the LED lamp even and comfortable for both our eyes and the nervous system. However, you can’t look directly at the working powerful LED, you can damage the retina.

LED lamp heating

Recall about heating. When working with LED lamps, an important feature related to heat generation, which manufacturers always take into account, is noteworthy. Since several small LEDs are placed in the lamp housing over a small area, it is required to remove heat from their substrates with the help of an additional radiator, the role of which is sometimes played by the lamp housing itself.


Thus, it is not allowed to heat the product above, in the worst case, about 90 degrees Celsius, depending, of course, on the power of the LED lamp itself - for low-power lamps, the maximum body temperature is much lower. This is not near with incandescent lamps, which are capable of causing severe skin burns when accidentally touched, even a few minutes after turning off. High-quality LED lamps will not cause burns.

Incandescent lamp and its analogue

Finally, LED bulb bulbs are made from durable, shatterproof, materials such as plastic or polycarbonate. For this reason, there is no danger of getting a cut (even if you manage to break the diffuser), which can not be said about incandescent lamps, nor about fluorescent lamps, which, when broken, produce numerous sharp fragments that can cause cuts.

The medical effects of light on humans

In conclusion, it will not be amiss to say that the latest studies of the effects of LED light on humans have shown that the soft light of LED lamps not only helps normalize the emotional state of people, but also helps maintain mental health, reducing stress in the work teams of office workers.

German scientists recently discovered the rejuvenating effect of LED light on skin cells, and medical research in recent years has generally shown that LED light accelerates the regeneration of damaged tissues and even neurons, these studies are ongoing, and medicine will probably soon receive another effective healing tool in its arsenal.

As you can see, LED lamps are not only safe for human health, but even useful!

    Yuri Mironov, incandescent lamps also flicker, and it is with a frequency of 100 Hz. The human eye is inertial, so we do not see these 100 Hz. If you put in the lamp circuit a diode that will cut one half wave, then the brightness fluctuation (flicker) of the incandescent lamp is very well felt. True, in fluorescent lamps with electromagnetic ballasts, flicker is more pronounced.

    The flickering of an incandescent lamp is slightly noticeable due to the thermal inertia of the filament.

    The flickering of fluorescent lamps leads to a stroboscopic effect, so they are usually used in pairs, including one of the lamps through a phase-shifting capacitor.

    If the mains frequency is 50 Hz, then the flicker frequency of the lamps should be 50 Hz. Where did 100 Hz come from?

    F.M, with a frequency of 100 Hz, the thermal energy oscillates, which is released on the spiral of an incandescent lamp (the lamp shines from the generated heat, which is proportional to the square I ^ 2 * R). And in the square of the current, the fundamental harmonic has a frequency of 100 Hz.

    LED lighting actually has one main drawback - like incandescent lamps, they heat up. But unlike incandescent lamps, they cannot work normally with strong heating. As a result, heat has to be removed from the LED light sources, and the more powerful they are, the more difficult it is to do it - the volume and weight increase. If there weren’t such a drawback, LED lighting would have replaced any other thing long ago). Although the lack of ultraviolet radiation in the spectrum is not always good. The fact that LED lamps are still more expensive will soon change - the economy always finds the opportunity to reduce the price of what is most needed and convenient to use.

    It is good to put energy-savers (mount) the base in the bottom. I got a 20-watt lamp - it doesn’t light up. Hanging a bulb, as usual, down. I disassembled it, and the zener diode already melted. I would show a photo, but I write here with a smartphone. There is simply no computer.

    It’s great that LED lamps provide soft light: my work schedule sometimes shifts to evening hours and it is imperative that my eyes do not get tired.
