If you really want to help save the planet, a good start is to change your lifestyle. There are many ways to do this – to eat moderately food, save water or to reduce the amount of electricity you spend. Even current of NPP is cheap, other sources compensate both the price and the levels of pollution that cause. But if you are really set themselves the task to reduce the amount of energy you use and save not less money for the family budget, LED bulbs are a good start in the right direction. Besides being more durable and up to 5 times more economical LED lighting offers you a huge variety in arrangement and design of the interior of your home. But back to the main topic – how LED bulbs in your home helping nature? Let’s see why LED lighting is a better choice for you and your home: Using LED bulbs reduce harmful emissions into the environment. The so-called “green energy” is too expensive, and not yet developed such technology. On the other hand still much of the electricity produced comes from power plants that use coal or other types of ground fuel. And this leads to the release of a huge amount of carbon in the atmosphere. But that may change if you use bulbs with LED technology. They consume less energy and are several times more efficient. So just will not need to produce as much electricity. Consequently harmful emissions will be reduced. LED lights are not wasting unnecessary energy. Incandescent bulbs are destroyer of electricity. 98% of their energy is released as heat and only 2% – for lighting. Click here to see how does LED lighting work. Better warm with air conditioning or heater. With bulbs costly. And their purpose is to shine, right? LED products do not contain harmful elements. Mercury and lead are among the most severe and toxic metals in nature. A flurostsentnite and halogen lamps work thanks to these two elements. Very often the old lamps are izvharlyani directly to the dumpster, not special places. Hence harmful metals soaked soil, and hence there are many ways in which to reach out to the human body. LED bulbs you save money every second when working Pessimists will say that, compared with other types of lighting, LED bulbs are more expensive. Yes it is, but they do not take into contingencies that higher initial investment is returned many times over the life of the bulb. In addition, as already mentioned LED bulbs are times effective, they provide much brighter light and last several years longer than flurostsentnite lamps.

Žarulje Struja je jedno od najvećih otkrića u povijesti čovječanstva, te se nerijetko kaže da je Nikola Tesla čovjek koji je izmislio 21. stoljeće. Nakon otkrića struje, ljudi su stvarali mnoge stvari koje rade preko struje, te je Thomas Edison izmislio žarulju. Žarulje su glavna stvar kod umjetnog izvora svjetlosti, te one električnu energiju pretvaraju u svjetlost.Postoje razne vrste žarulja, a najpoznatije su naravno žarulje sa žarnom niti koje vjerojatno i vi koristite u svojem stanu. U novije vrijeme sve veću popularnost stekle su i LED žarulje, a razlikujemo još i druge vrste žarulja poput halogenih ili štednih. Prva žarulja s žarnom niti pojavljuje se početkom 20. stoljeća, točnije 1906. godine, a napravio ju je Thomas Edison. U njoj se je nalazila karbonizirana bambusova nit, te je žarulja mogla svijetliti preko 1000 sati odjednom, bez paljenja i gašenja. Nažalost vijek trajanja žarulja nije se puno promjenio, jer paljenje i gašenje mnogo utječe na vijek trajanja žarulja i ukoliko se češće pale i gase veća je mogućnost da pregore. Iako su najpoznatije (i ujedno najstarije), žarulje s žarnom niti nisu najbolji odabir za osvjetljenje prostorija. LED žarulje u zadnjih nekoliko godina stekle su veliku popularnost, a glavni razlog tome je upravo to što traju puno dulje nego žarulje s žarnom niti, te troše manje električne energije. Žarulje s žarnom niti 95% energije koju koriste pretvaraju u toplinu, te samo 5% u svjetlost. Glavni razlog tomu je što se žarna nit žari, te na taj način proizvode svjetlost. Naravno, žarulje s žarnom niti jeftinije su od LED žarulja, ali ukoliko pogledate to da LED žarulje traju znatno duže, njihova kupnja se isplati. U nekim zemljama žarulje s žarnom niti već su zabranjene zbog uštede električne energije, te ukoliko razmišljate o tome za koji način osvjetljenja se oprijedjeliti, LED žarulje su puno bolji izbor. Ostale vrste žarulja su manje popularne iz razloga što imaju dosta više nedostataka. Primjerice u štednoj žarulji nalazi se živa koja je kancerogena i otrovna. Ukoliko vam se štedna žarulja razbije, ta živa odlazi u zrak i šteti ljudima i životinjama. Stoga, ukoliko vam se je u nekoj prostoriji razbila štedna žarulja, otvorite prozore i napustite prostoriju dok se ona ne prozrači.
