LED lamps can damage eyesight. Blue Light Hazard is influencing your health.

LED lamps myths that are repeated, first and foremost those skeptical geared to such lighting. Meanwhile LED light like any other source of light, it is safe spectrum for vision and provided certain technical requirements. Unquestionable advantage LED lighting is energy efficiency and long life. Unlike traditional bulbs, such light sources consumes 10 times less power and is more resistant to damage. In addition it can be a great decorative element, emphasizing the character of the Interior. Consequently, more and more people choose to purchase this type of lighting, it is often not reflecting on whether or not it has an effect on our health.

How does LED lighting works?

The intensity and the colour of artificial light can affect mood, concentration or mental state of man. Excessive contact with this type of lighting should be avoided primarily children and those affected by the Afakia (demage lens in eye) or wearing artificial lenses. Too blue light emitted by the led lights affect the retina and according to researchers may consequently result in degeneration of his the most light-sensitive parts. We are talking of course about the so-called “blue light hazard”, or the risk of damage to the retina with blue light. This is the most popular bogey associated with modern LED light sources. Let us remember, however, that this is a myth, because these observations are carried out exclusively on experimental models and are not supported by other evidence. In addition, radiation is part of the blue spectrum in both daylight and artificial light produced.

Of course, in the case of low quality LED lighting may appear more or less noticeable flicker effect. Can often be the cause of many unpleasant diseases, causing burning and itching eyes, problems with concentration of attention, pain and dizziness, and even hyperactivity. Therefore, you might want to choose a better quality lighting, offered by the best producers.

The crux of the matter

Let us remember that the LED lamps do not threaten our eyes, if they are made in accordance with technical standards, including those relating to the safety of foto-biology. Conformity of lamps with these requirements to protect our sight before high brightness (luminance) and excessive exposure to blue light. The law imposes the obligation on the producer to meet the standards. Before the introduction of the lamps on the market, the manufacturer carries out laboratory testing to confirm that they are safe for the user. This fact takes note of the Declaration of conformity (manufacturer’s declaration). Wholesale vendors and retailers should require the presentation of the Declaration of conformity and the results of laboratory tests. All this to ensure safety and the declared quality lamps.

The reality of consumer

Unfortunately, the reality of the market is not conducive to consumers. In the shops there is a lot of LED-lamps of unknown origin. The predominant brand, which are not identified with the manufacturer, which usually means that under the brand name conceals the lamp from a variety of manufacturers and of varying quality. When you buy LED lamps must be exactly watch and ask the seller to change several different lamps. This can help in identifying which lamps high brightness due to the poor design of the optical system, and often with the lack thereof. In this type of solutions to individual LEDs are directly visible. The light that blinds, lamps, and long-term exposure leads to damage sight. An excessive quantity of blue light emitted by the LED lamps can also result from the use of poor quality (low) pitch. Manufacture of light hues of white LED by takes place on the basis of the conversion of luminance, which in simple terms means mixing blue light LEDs with yellow light emitted by the phosphor. This effect creates the impression of white light. The use of cheap (low performance) phosphor causes that too large a part of the blue light goes out from the led. Good quality phosphor is a large share of the cost of manufacture of the LED lamps and affect the price at which the Doe buys the lamp.

What can you handle?

The quality and safety of optical illumination are important for our health, well-being and productivity. It is worth to purchased by us LED lamps were of good quality, at least at the level provided by the applicable law. How to choose a lamp LED, since its compliance with the requirements can be checked only by using special measuring equipment? In this situation, the essence of choice becomes a confidence in the experience and reliability of the manufacturer. It should also seek distributors, using tools that allow them to check the quality of the product as sold. The consumer should also benefit from the right to claim and the right to the market surveillance authorities and consumer protection the suspicion as to the quality or safety of bought the lamp.
