Is LED lighting safe?

Nowadays, we are not able to function without artificial lighting, so it is so important that the light source is healthy for our body, and at the same time energy-saving. The market is rich in various lighting products, and modern technology allows you to optimize their functions, depending on the purpose. When buying a bulb, we pay special attention to its technical side, but it is not the only factor that should decide on the choice of lighting.

A professionally active person spends most of his time in closed rooms that require lighting with artificial sources. This fact should force us to choose safe and healthy lighting, both when it comes to our work and study places, as well as houses or flats. Particular attention should also be paid to the time of day and year, in the autumn and winter period there is much less sunlight, so we are forced to use its artificial counterparts for a longer period.

From an early age, it is worth remembering choosing the right lighting. Our children spend about 200 days in schools and universities every year, for several hours a day. The impact of the quality of light sources on eye health is one issue that parents especially worry about. They are fully aware of how lighting affects school performance and the well-being of their children.

Saving money on the quality of light can have serious consequences. Just a few months after the purchase, our body may feel the first negative effects of harmful lighting - headaches, problems with concentration, nausea, fatigue and watery eyes. That is why it is so important to choose products that meet the photobiological safety standard.

Photobiological Safety Standard

The IEC 62471 standard, i.e. photobiological safety standard, requires manufacturers of lighting to control the intensity of electromagnetic radiation and adapt it to the applicable regulations. It is worth mentioning a few risks to both the eyes and the skin that can occur if these requirements are not met:

  1. Eye and skin hazard from UV actinic radiation
  2. Eye hazard from UV-A radiation
  3. Blue light eye hazard
  4. Infrared (IR) eye hazard
  5. Thermal skin hazard
  6. Thermal hazard of the retina.

It is worth knowing that on the bulbs' packaging we will not find information about photobiological standards, because it is not required - we have to look for the data directly from the manufacturer.

Factors influencing the quality of lighting

Adequate lighting is not only a matter of improving visibility, but also a stimulant to action and regulating the circadian rhythm of our body's functioning .

That is why it is so important to choose the right lighting, its quality completely affects our well-being, health and work efficiency. So it's worth paying attention to several factors:

  1. The color of light - warm - helps us relax and calm down, it is recommended to use such lighting in the bedroom, living room or relaxation area; neutral - it has a stimulating effect, so it is worth using it in offices; cold - strongly stimulates, is used in industrial and commercial spaces.
  2. The color rendering index - Ra, is expressed in the range from 0 to 100. The higher this index is, the better the colors are rendered and the illuminated objects look more natural; in the rest area, the Ra level should reach 60-80, in the work area or bathroom, above 80.
  3. Luminous intensity - the luminous flux (Im) depends on its practical application - when resting and relaxing, it is worth using softer lighting, in the kitchen or at the desk it is better to install a stronger light.

Why choose LED technology?

When arranging lighting, lighting manufacturers recommend the use of LED technology. Among the many advantages, it is worth mentioning, among others LEDs have a longer lifetime compared to traditional light bulbs, the heating up is significantly smaller during use and the product is more energy-efficient. In addition, the voltage does not change the color of the lighting, which emits light similar to natural. Thanks to these features, LED technology is widely used, from heavy industry to home decoration.

LED technology allows for the emission of a variety of colors, with the help of which you can create a space corresponding to a specific need. In the office space, it is worth using red, blue and yellow colors - they allow you to stimulate the body and mind and affect the efficiency of work. In rest areas, our houses and apartments, it is best to install lamps that emit light similar to sunlight. The environment can be enriched with green lights, which, according to psychologists, have a positive effect on the human nervous system.

Due to its functionality and safety, LED technology has become the best alternative to traditional light sources.
