LED LIGHTING: MYTHS AND REALITIES

MYTHS AND REALITIES OF LED LIGHTING

Every time comes a new technology being developed and implemented at high speed as LED lighting emerge staunch detractors and unconditional followers. The LED lighting meets all the requirements to become one of those technologies that look like one or several rivals: android or iPhone; diesel or gasoline; Windows or Mac; LED, fluorescent or sodium vapor.

And the question occurs in most cases, the answer "what is better?" Is not unique. Depending on the use you're going to give, hours of use or the place, we agree to go for one or the other technology.

Here we review some of the myths (or realities) over repeated around the LED technology. True or false?

THE LED LAMPS ARE EXPENSIVE: FALSE

Require more than other types of lamps initial investment, but this investment is beginning to recover from the first bill, so very short term are much cheaper. Of course, no hard to acquire indispensable peseta and the lamps manufacturers, importers or distributors official and recognized, to give us all product warranties just purchased.

AN LED INSTALLATION IS NOT ALWAYS THE MOST CONVENIENT: TRUE

It is essential to conduct a thorough study of the lighting requirements of each installation. Sometimes, LED technology may not be the most appropriate because, for example, hours of use. An installation requires a significant investment, which in most cases recover quickly. However, we must carefully consider the lighting needs to choose the best option. The professionals will tell us what kind of lighting for us. In fact, sometimes we need to pursue a different type of lighting for every room.

THE LIGHT FROM THE LED LAMP PRODUCES MORE LIGHT POLLUTION: FALSE

An LED lamp whose light output is properly directed not generate more light pollution than other lamp. In fact the unidirectional light output of the LED makes it easier to control it and direct it to the desired location. It is true that, by their nature, the light emitted by an LED lamp is more easily spread through the atmosphere, but this is easily avoidable with proper installation that conforms to the rules governing such facilities.

THE LED LIGHT IS HARMFUL HEALTH: FALSE

LED lamps do not emit infrared or ultraviolet radiation and contain no mercury, so they have less potential to be harmful in every way to health.

It is said that white light generated by LED lamps (which is achieved by applying phosphor coatings to the original blue light emitting chip) inhibits secretion of the hormone melatonin in humans, which occurs only in the dark, and it is essential to regulate the biorhythms of the human body (including the so-called circadian rhythms ). This is true half.

Any light radiation affects the production of melatonin (the sunlight and artificial, either a fluorescent or LED lamp). For example, if you work in an office for eight or nine hours straight, inadequate lighting (either LED, fluorescent or sodium vapor) can affect our body causing "mismatches" or discomfort: sleepiness, fatigue or dizziness or pain head (especially in the case of defective or poor quality fluorescent).
