As we all know, incandescent is an important invention of Edison, which helps us say goodbye to darkness and usher in light. However, incandescent is famous for power consumption. It’s estimated that only 10% energy is able to be converted into light energy while the rest are converted into heat energy to waste in vain. Therefore, in the past years, people are searching for new light source to substitute incandescent. Compact fluorescent(CFL) lamp emerges at the right moment. With the advantage of simple production and low price, CFL has been widely used in many fields and gradually taken the place of incandescent.
Even though CFL can save energy, its tube contains mercury. The reason why CFL gives out light, mercury is an element to be reckoned with. In other words, CFL can’t glow without mercury. Thus it can be seen that CFL replacing incandescent is only a temporary expedient but not the best ideal light source. With the widely used of CFL, the majority people begin to focus on its defect. CFL has mercury pollution during production and discard, which not only damages healthy but also pollutes environment. Besides, as a glass product, it is easy to broken and very hard to transport and install. As for power consumption, it still wastes a lot of energy. Moreover, its longevity is so short that it can save a little energy but waste money.
At this moment, LED technology has had great progress. The luminous efficiency has astonished breakthrough while the price has gradually decreased. Energy saving and longevity is now synonymous of LED. It is able to work normally in high speed condition. What’s more, LED Light is solid-state encapsulation and cold light source. It is convenient to transport and install. Believe it or not, LED time has come over unannounced and rapidly developed. It’s believed that LED Light would totally replace CFL and become the new generation of light source. See, led high bay is an omen.
