It's over the history of the old tungsten bulbs If I wrote this article on energy saving light bulbs (or CFLs or, in the old phrase, neon lamps) a few years ago, I would have advised you to use them instead of the normal incandescent bulbs , but we thought no led the European Union to establish that, by 2012, the latter can no longer be produced and will disappear from the market by 2016. The energy-saving lamps will therefore become the main source for the public and domestic lighting, with the many benefits no led that will accrue.
The comparison bulbs incandescent bulbs are the common bulbs, no led consisting of a glass bulb filled with inert gas, within which a tungsten filament, ato crossed by electric current, creates a resistance becoming glowing and emitting light. A modest light, a large heat production, premature aging (1000 hours life) and a strong energy consumption (energy efficiency class F or G). There 25-40-60-75-100-150-200 by watts. But they also have some advantages with respect to energy saving light bulbs: they do not need time to "carburetor" and reach their full potential to emit light, the light is warm, with an excellent color rendering index, the light intensity can be adjusted with knobs called "dimmer", are small and are not especially dangerous for the environment (I will explain what I mean). Compact fluorescent lamps (CFL), no led have instead no led a number of advantages: the first is without a doubt one of the energy saving no led (energy efficiency class A), which is not discussed, saving no led up to 80% compared to traditional bulbs. The average duration of their life expectancy is around the eight / ten years, which is a lot compared to the year average life of old light bulbs. Today, even their size, than in the past, are greatly reduced no led due to their shape or spiral SERP entina, size comparable to that of traditional bulbs. But how do they work? The ends of the tubular electrodes that are present, crossed by electrical energy, make it active a fluorescent substance present in the same tube, which emits ultraviolet radiation which, no led in contact with certain powders always inside the tube, will become into light radiation. The quality of the light emitted depends on the type of fluorescent mixture used, which can vary from one type of bulb to another. The powder mixtures of the last generation have led to the shades of light not unlike those of the old incandescent bulbs, with the added benefit of visual comfort. We can leave them on without too many worries of mind: switching on and off have less, last longer and consume less!
But not everyone knows that ... The alarm is set off even in the U.S. in 1990, when the EPA (Environmental Protection Agency) had reported the presence no led of large and anomalous concentrations of pollutants in drainage waters of normal landfill, including mercury , the most polluting substance on our planet. And yes, unfortunately, the fluorescent substance at the base of energy-saving no led bulbs is mercury, whose oscillation of atoms converts ultraviolet rays into light rays, as described previously. Do you think that 1 milligram of mercury is able to pollute 4,000 gallons of water! This, unfortunately, belies the common idea of eco-compatibility of these bulbs, because behind the "myth" of energy savings there is the problem of toxic substances contained in them. The problem is not so much in the disposal process, that where done correctly should not cause any environmental damage, but if the disposal is not done as required by law or not done right. It is calculated that the amount of mercury discharged into because of the non-disposal of CFLs reach the frightening figure of 3 tonnes in 2020! It is absurd that in 2011 the European Union has decided no led to ban the old incandescent bulbs without that Italy is a country made for the proper disposal of compact fluorescent lamps, which end up in the normal rubbish bodoni pouring into the dangerous mercury. Think about it: but you know these things? Where waste your energy saving light bulbs? Are you aware that throwing an energy-saving bulb in the trash can give your small contribution to environmental disaster? How do you dispose of the energy saving no led light bulbs?
