There is no doubt that LED is the trend of lighting applications in the further. With minimum impact on the environment and high efficiency, LED lights are becoming more and more popular. Though LED potential can be traced back about one hundred years ago, the practical applications are just developed in past years.
To fully understanding why the LED has the great advantages compared with some traditional lighting sources, you may need the background of optoelectronic knowledge. This is not the things we are going to discuss here. Just as a common consumer, what we really care about are their practical advantages we can benefit from in our daily lives. Here I list the five main advantages of LED lights as blow:
The biggest reason people choose LED light to replace the traditional light is that LED can save a lot of energy. It means that with LED applications, less resources will be consume, less money the consumers need to pay on their electrical bills. It is simple to explain: we used to use 60 watt incandescent bulb for household use, but now, to achieve the same lighting effect (same lumens), we just only need 7 watt LED light bulb as a replacement. It sounds a little incredible, but that is the true. In the lab, the efficiency of LED can reach to 200lumens/watt, ten higher than the incandescent can achieve. This is the biggest selling points for LED manufactures to promote their products.
LED lights are Friendly to the environment. As we have mentioned above, LED consume less powers to produce the same lumen light, less powers means less resources will be taken to generate electricity. In addition, the pollutions caused by LED lights are negligible especially comparing with the fluorescent lights, which contain the mercury contents. We all know the mercury significantly pollute our water. To protect the environment from such pollution, eco-friendly LED lighting is the solution to this issue.
Long lifespan is another attractive point. In general, the incandescent own a life cycle ranging from 1,200 hours to 2,500 hours. The fluorescent lights may be celebrated to announce have a capacity of working about 12,000 hours. Don’t be stunning about this figure too early, as the LED lights prolong it to 50,000 hours. You might need to replace one or two incandescent bulbs every single year, but when use LED lights, forget it, since they can last for decades.
While we are talking about its high-efficiency, eco-friendly, long lifespan, all right, they are good, but what is the cost? Years ago, the LED lights are too expensive to purchase for the householder. Only some up-scale hotels and shopping malls can bear high prices. But as the rapid development of LED industry, the costs are now significantly reduced. that is why we are now often see the news reports that government slash the cost of municipal projects by introducing LED lighting applications. So in a word, for a long run, the LED lights are less expensive than traditional light sources.
