The harmful Led lamp for man

LED lamps have a firm grip contemporary lighting market and is almost universally replaced the other types of lamps. But, despite such total dominance, still do not cease talking about the dangers of Led bulbs to human health. So let this article will try to understand what kind of damage can cause Led lamps and how it can be eliminated. So, let's begin.

Pros and cons of LED lamps

And we will start with you with a brief summarization of the positive and negative aspects of LED lamps and start with the pros.

pros

1. The most "fat" plus LED bulbs is their efficiency. If we compare this figure with conventional lamps, the lamps Led economical several times (3-5 times). And since the cost of a kilowatt-hour is growing, the economy is growing.

2. The duration of the work. The average duration of the alleged operation of LEDs is about 30,000 hours, which is significantly more work incandescent bulbs (1,000 hours).

3. Security. The design Led lamp does not use toxic components, and the bulb is made of plastic, so even if the lamp falls and broken, the plastic bulb glass is much safer because it does not leave sharp shards and get hurt just impossible.

So, let us now proceed to consider the negative aspects of using LED lamps:

Minuses

1. Adverse effects on the eye. If the production technology is broken, then the source of UV - radiation, which is used in the lamp may have a negative impact on a person's vision. Of course, modern technology virtually eliminates even the probability of this defect, but to We are still manufacturers that use outdated technology, which allows a defect.

2. Increased ripple of light. Since the driver is integrated in each lamp transforms the AC component into a constant, then inevitably the formation of light pulsations at a certain frequency. But since human vision has inertia, we just do not notice it flicker.

But if the production of a dishonest manufacturer of components used extremely poor quality and inappropriate denomination the ripple of the allowable range pass away in an invalid, which will inevitably have an impact on the psycho - physical condition body.

The impact on the human body

Vision

Note. Observed white light, which emits working Led lamp, is obtained as follows: a diode emits a light wave length of 470 nm (blue light). Damage on top of the phosphor transforms the radiation into the light that we see as white.

Before you purchase Led lamp, pay special attention to such parameter as the color temperature. After all, the higher the value, the greater the intensity of radiation in the blue spectrum.

The retina of the human eye particularly sensitive to blue light and if the long and high frequency expose it to such radiation, it may cause degradation. Particularly sensitive to such light children's eyes, which are in the formative stage.

Therefore, to minimize the negative effects of blue light is recommended to use a LED light bulb with a color transmission 2700 - 3200 K.

Effects on the nervous system

The flickering light source with a frequency of 8 - 300 Hz have a depressing effect on the human nervous system. Health Standards for the house is better to use light bulbs with a ripple factor of 10%. Such indicators can achieve light bulbs, which use quality drivers. And since quality components may not be cheap, and the price of such light bulbs can not be minimized.

Suppression of melatonin secretion

Have you ever noticed for a such a long time that if you work long hours and under a bright LED light, then going to bed quite difficult to get to sleep? So due to the fact that the bright light from the LED acts as a backstop production of this important hormone.

Therefore, when it is dark it is best to avoid bright light, especially in the common rooms and bedrooms.

How to minimize damage

Analyzing all the above it can be concluded that high-quality and properly fitted Led lamps have a minimal adverse effect on the human body. Therefore, when choosing an LED lamp focuses not only on the price tag, but also on the quality of the product and place them where they will be most effectively used.

Remember the most important thing on their own health is not worth saving, it is better to buy quality and sleeping lamp strong and healthy sleep.
